When practitioners ask “does RETT apply to my transaction?”, they are really asking two separate questions. First: is this a real estate transaction at all under the RETT Law? And second: is it exempt? This article answers the first question comprehensively. The exemptions are covered in Cluster 3.

RETT is imposed on any transaction that produces a legal effect resulting in the transfer of real estate ownership, possession for the purpose of ownership, or the right to benefit from real estate. That definition — drawn directly from the RETT Law (Royal Decree No. M/84) — is deliberately broad. The Saudi legislator was not trying to tax only arm’s length cash sales. The regime catches every form of real estate transfer, regardless of its commercial structure or the label the parties put on it.

ZATCA’s Detailed Guideline (Version 6, May 2026) makes this explicit: the transaction may arise either from the meeting of two wills (a bilateral agreement, such as a sale or barter) or from the unilateral act of the assignor alone (such as a will or bequest). The form of the transaction is irrelevant. What matters is the legal effect — did real estate ownership, possession-for-ownership, or the long-term right to benefit move from one person to another?

ZATCA’s Guideline identifies the following transaction types as taxable events under the RETT Law. This is not an exhaustive closed list — any transaction that meets the legal definition above can trigger RETT — but these are the categories most commonly encountered in practice.

The most common mistake in practice is assuming that RETT only applies to commercial arm’s length sales. It does not. A gift of real estate is a taxable event. A barter is a taxable event — and in a barter, both parties are assignors, meaning two separate RETT liabilities arise simultaneously.

The reason gifts create a taxable event is structural: the RETT Law defines the trigger as a transfer of ownership, not a sale. Ownership can transfer without cash changing hands. The law does then provide specific exemptions for certain gifts (to spouses and relatives up to the third degree, under prescribed conditions) — but the exemption must be actively established, not assumed. The starting position is always: this is a taxable event.

For wills and bequests: the transfer upon death pursuant to a documented legal will is a taxable event under the RETT Law. However — and this is important — the distribution of a deceased estate to heirs according to their legal shares under Islamic inheritance law is separately categorised and treated as exempt. These are different scenarios. A will that goes beyond legal shares, or that involves cash compensation between heirs, moves outside the exempt category.

RETT applies to real estate situated in the Kingdom of Saudi Arabia. The RETT Guideline defines real estate as any immovable property within the Kingdom, including land, everything built or constructed on it, and fixtures and equipment permanently attached to a building or structure that form a fixed part of it.

Critically, the Implementing Regulations extend this definition to include movable property placed by its owner within their own real estate if it is intended for the permanent service or exploitation of that real estate — even if it is not permanently affixed. This means that specialised industrial equipment, permanently installed production machinery, or other assets intended to permanently serve the real estate are treated as part of it for RETT purposes. The practical implication: when selling a factory or industrial facility, the RETT base may include more than just the land and building.

Permits, primary and secondary rights in rem, and other rights closely linked to the real estate (making them inseparable from it) are also included in the total value of the real estate for RETT purposes under Article 2 of the Implementing Regulations.

This is one of the most commercially significant — and most frequently misunderstood — aspects of the RETT regime. Under Article 2 of the Implementing Regulations, transferring shares or interests in a company, fund, or entity that qualifies as a “Real Estate Company” is treated as a real estate transaction and is subject to RETT.

A company qualifies as a Real Estate Company when: (a) it directly or indirectly owns real estate in the Kingdom for the purpose of generating revenue by selling or leasing it, and (b) the total fair market value of such real estate is not less than 50% of the total fair market value of the company’s assets — measured on the date of the interest transfer, or at any time in the 365 days preceding that date.

The 365-day lookback is deliberate. It prevents parties from temporarily restructuring a company’s asset mix to avoid the 50% threshold immediately before a planned share sale, then reverting to a real-estate-heavy position afterwards.

Not every share transfer in a Real Estate Company triggers RETT. The trigger requires that a person, or a group of persons acting in agreement, dispose of a total of 30% or more of the company’s interests through one or more related transactions within any three-year period, starting from or after the date on which the holding reaches 30% or more.

The capital increase exception is also worth noting: owning new shares resulting from a capital increase is not treated as a real estate transaction if existing shareholders’ proportions remain unchanged, or if new shareholders enter but existing shareholders hold their original shares for five years from the capital increase date.

Saudi real estate is heavily financed through Islamic structures — Murabaha, Ijara, and Finance Lease arrangements are the norm rather than the exception. The RETT Law addresses these directly, and the principle is straightforward: only one RETT event arises per real estate transaction, regardless of how many legal transfers occur within the financing chain.

In a standard Finance Lease or Murabaha structure, the financing entity (typically a bank) purchases the property from the seller — that first purchase is the taxable RETT event. The subsequent transfer of ownership from the financing entity to the customer (after installments have been paid) is not a second taxable event, provided: (a) both transactions are specified in the financing contracts issued by the entity, (b) the parties and the real estate description have not changed, and (c) the value stated in the financing contracts has not changed.

The implicit profit margin (the bank’s markup) is excluded from the RETT base in licensed financing contracts. RETT is calculated on the original purchase price — the underlying real estate value — not the total amount the customer ultimately pays over the financing term.

This rule applies equally to Islamic Ijara ending in ownership, lease-to-own structures, and Murabaha contracts. The key is that both legs of the transaction must be documented within the same financing contracts. If the structure changes, or if parties change, or if the property description is altered, the protection falls away and a new taxable event arises.

Two less-obvious triggers deserve particular attention given their prevalence in large-scale Saudi infrastructure and Vision 2030 projects.

Long-term usufruct rights exceeding 50 years are treated as real estate transactions under the RETT Law. The tax due date is the date the right is granted. There is a 30-day cancellation safe harbour: if the usufruct grant is cancelled within 30 days of its creation, RETT does not arise. The tax base for usufruct rights is the present value of the fair market value of the right, or the present value of the total agreed consideration over the entire usufruct period — whichever is higher. This can produce a significant tax liability on long-term concession arrangements, and the calculation mechanics are more complex than a standard sale (for full details, see Article 2.7).

Build-Own-Operate-Transfer (BOOT) projects are a distinct category with a specific due date rule. RETT is not triggered when the BOOT contract is signed. It arises on the date of the actual transfer of ownership to the transferee — meaning the date on which all conditions required by the contract for the ownership transfer are met. This distinction matters significantly for project planning: the RETT liability can arise many years after the original contract date, and its quantum is based on the fair market value of the real estate at the actual transfer date (see Article 2.11).

Knowing what falls outside the scope of RETT is as important as knowing what falls inside it. The Implementing Regulations identify several situations that are explicitly not real estate transactions for RETT purposes.

• Subdivision of real estate by competent authorities: The subdivision of land according to official subdivision procedures is not a real estate transaction. This covers the administrative parcelling of a plot into multiple plots — the ownership does not transfer, only the land registry description changes.
• Partition of jointly-owned real estate meeting specific conditions: Where co-owners of real estate registered under a single title deed partition it into separate parcels in proportion to their existing recorded ownership interests, with no financial consideration between the parties, this is not a taxable event. All three conditions must be met: single title deed, proportional partition, no compensation between parties.
• Capital increases where ownership percentages are unchanged: A Real Estate Company increasing its capital where existing shareholders maintain their pro-rata percentages does not constitute a real estate transaction.
• Transfers of listed securities in a Real Estate Company on a licensed capital market: The purchase and sale of listed shares in a real estate company on a Saudi-licensed exchange is explicitly exempt. This includes public offerings, secondary market trading, and a listed company buying back its own shares in compliance with applicable rules.
• The second leg of a Finance Lease or Islamic finance structure: As discussed above — the ownership transfer from the financing entity to the customer under the same contract conditions is not a new taxable event.

Article 6 of the Implementing Regulations addresses a specific enforcement concern: arrangements where the parties create documents that give a different form to the real estate transaction, concealing the actual transaction or implementing arrangements that do not reflect the true rights and obligations.

The principle is simple: RETT is assessed on the real transaction, not the documented one. If two parties execute a nominal loan agreement over a property while one party actually takes beneficial ownership, ZATCA has the right — upon discovery — to treat the actual beneficial transfer as the taxable event and assess RETT accordingly. The 3-year reassessment window for disclosed transactions (and the longer period for undisclosed ones) applies from the date of ZATCA’s knowledge of the real transaction.

The penalties for evasion extend well beyond late-payment fines. The anti-evasion provisions under the RETT Law create liability for both parties where concealment is established. This is an area where ZATCA has broad investigative powers.

For any Saudi real estate transaction, run this sequence before proceeding:

1. Is real estate situated in Saudi Arabia involved? If no — RETT does not apply. If yes — continue.
2. Is there a transfer of ownership, possession for the purpose of ownership, or the right to benefit from the real estate? If no — RETT does not apply. If yes — continue.
3. If the transaction involves company shares or interests: Does the company qualify as a Real Estate Company (≥50% real estate by FMV on the transfer date or in the preceding 365 days)? If yes, does the transfer (including related prior transfers in the 3-year window) reach 30%? If both — RETT is triggered on the real estate component.
4. If the transaction involves a usufruct right: Does it exceed 50 years? If yes — RETT is triggered on the date the right is granted.
5. If the transaction is part of an Islamic finance structure: Is this the first transfer (financing entity purchases from seller) or the second (financing entity transfers to customer)? First — RETT applies. Second — check if the single-transaction conditions are met.
6. Is there an applicable exemption? Run the exemption analysis separately. See the complete exemptions guide.

There is no paper filing system for RETT. No forms to post, no stamps to obtain manually, no queues at a government office. The entire RETT compliance process in Saudi Arabia runs through ZATCA’s electronic portal at zatca.gov.sa — and it runs there exclusively.

Under Article 11(a) of the Implementing Regulations, the transferor (or their representative) must register every real estate transaction — whether taxable or exempt — through the portal. This is a mandatory requirement. The act of registration constitutes an acknowledgment by the transferor of the accuracy of the information provided.

The portal is designed to be the gatekeeper for the entire RETT process: the transaction goes in, the system calculates the RETT due, generates a payment invoice, and once payment is confirmed, issues the clearance that the Notary Public needs before completing the title transfer. Without this clearance, the deed cannot be registered.

Saudi nationals purchasing their first home may be entitled to a government-funded RETT relief under the First Home programme. The mechanics work differently from a straightforward RETT filing:

1. The buyer (not the seller) initiates the process by obtaining a “First Home” certificate from the Ministry of Housing’s portal (wafi.housing.gov.sa), confirming eligibility for the government subsidy
2. The buyer presents the First Home certificate to the seller (transferor) prior to the RETT registration step
3. The seller incorporates the First Home certificate reference into the ZATCA portal registration
4. ZATCA processes the subsidy — the government effectively bears the RETT up to the applicable first home ceiling (SAR 1,000,000 from the original 2020 introduction), with any excess RETT on values above that ceiling borne by the seller in the normal way

The seller’s responsibility here is to ensure the buyer’s First Home certificate is valid and to process it correctly through the ZATCA portal. If a First Home certificate is fraudulently claimed or incorrectly applied, the RETT liability defaults to the transferor.

Errors happen. The Regulations provide a correction mechanism. Under Article 11(b), the transferor can submit a Correction Request through the ZATCA portal if the registered transaction data is incorrect. The rules:

• The correction request must be submitted within 30 days from the time the transferor becomes aware the registered data is incorrect, or upon the occurrence of any event that leads to a breach of exemption conditions
• If the correction results in additional RETT being due, that amount must be paid by the applicable payment deadline
• If the correction results in a reduction in RETT due, a refund can be claimed (subject to the refund process under Article 9 of the Regulations)
• When submitting a correction, the transferor is notified that ZATCA retains the right to re-evaluate the property

This correction mechanism is relevant not only for genuine errors but also for transactions where exemption conditions are later breached. For example, if a property was transferred using the group restructuring exemption and the required five-year holding period is subsequently violated, the transferor must submit a correction request and pay the RETT within 30 days of the breach.

RETT compliance does not end at payment. Article 11(f) of the Regulations specifies the documents that must be kept and the retention periods:

Records may be maintained in physical form or electronically — provided they are stored within the Kingdom (or accessible remotely with appropriate controls) and are protected against tampering. If ZATCA conducts an examination within the three-year assessment window, it can demand any of these records within the examination process.

For transactions that do not go through the Notary Public — principally share transfers in real estate companies, usufruct right grants, and BOOT project completions — there is no built-in enforcement mechanism to guarantee RETT compliance. The parties must proactively manage the 30-day payment window.

The filing process is the same (ZATCA portal registration and payment), but the sequencing is driven by the applicable due date under Article 4 of the Regulations, not by a notary appointment. Key points for non-notarized transactions:

• For share transfers in real estate companies: registration must be submitted by the payment due date (within 30 days of the trigger). Registration for publicly offered securities and listed securities trading is not required (Article 11(a)(6)).
• For usufruct rights exceeding 50 years: RETT registration and payment must be completed within 30 days of the date the right is granted
• For BOOT completions: within 30 days of the actual transfer date

Missing these deadlines triggers late payment fines under the RETT penalty framework — and without the notary as a procedural gatekeeper, it is easy for these deadlines to be overlooked, particularly in complex M&A transactions where real estate issues are one element of a larger deal.

Timing matters in RETT. Get it wrong and you are not just late on a payment — you are triggering fines, penalties, and potentially a ZATCA investigation. Understanding exactly when RETT becomes due is not a theoretical exercise; it is a compliance imperative for anyone involved in Saudi real estate transactions.

The default rule under Article 4(g) of the Implementing Regulations is straightforward: the RETT due date is the earlier of (a) the date an unconditional agreement is concluded in relation to the real estate disposal, or (b) the date ownership actually transfers.

The phrase “unconditional agreement” is significant. An agreement is unconditional when it binds both parties without any remaining conditions that could prevent the transfer from proceeding. A binding sale and purchase agreement (SPA) with no outstanding conditions precedent is an unconditional agreement — even if notarization has not yet occurred. When those parties sign that SPA, the RETT clock starts running.

Many parties assume RETT is due at notarization. That is a common and costly mistake. The notarization step is required to complete the title transfer, but the RETT obligation crystallises at the earlier of unconditional agreement or actual ownership transfer — whichever comes first.

Article 4 of the Implementing Regulations goes beyond the general rule to specify the RETT due date for categories of transaction where notarization does not occur (or occurs later than the transfer event). Each category has its own rule:

The due date of RETT and the payment deadline for RETT are related but distinct concepts. Under Article 5 of the Implementing Regulations, different payment deadlines apply depending on transaction type:

Standard Notarized Transactions

For the majority of property sales that proceed through the Notary Public, RETT must be paid on or before the date of notarization. The notary serves as the enforcement mechanism — no payment, no title transfer. This is a hard deadline with no grace period built into the system.

Share Transfers in Real Estate Companies

Where RETT is triggered by the transfer of 30% or more of shares in a real estate company, payment must be made no later than 30 days from the earlier of: the date shares transfer or the date of the unconditional agreement (Article 5(A)(1)). There is no notary backstop here — the parties must proactively manage this deadline.

Non-Notarized Transactions (General)

For non-notarized transactions (usufruct rights, BOOT completions, possession transfers for ownership purposes), RETT must be paid within 30 days from the RETT due date as determined under Article 4 (Article 5(B)).

Off-Plan Sales

As a specific exception, for off-plan property sales, RETT must be paid on or before the date of notarization (Article 5(C)). This aligns with the general notarized transaction rule — the notary will not complete the transfer without RETT confirmation.

Conditional Exemptions That Become Taxable

If a previously exempt transaction loses its exemption status due to a breach of conditions, RETT must be paid within 30 days from the date of the breach (Article 5(A)(2)). The transferor must also notify ZATCA via a correction request within 30 days of becoming aware the data is incorrect or the exemption condition is breached.

Off-plan transactions have a materially different RETT timing rule that is frequently misunderstood. When a buyer purchases a unit off-plan — before construction is complete and before a title deed exists — the RETT due date is the date of notarization with the Notary Public or Accredited Notary, not the date the off-plan purchase agreement is signed (Article 4(e)).

This means RETT is not due when the off-plan sale contract is executed. It is due when the completed unit is notarized — which could be one, two, or more years later. For developers managing large off-plan projects, this deferred RETT obligation must be built into financial planning. The RETT liability crystallises at completion, not at booking.

The same timing rule applies for resales of off-plan units before completion. If an off-plan buyer resells their unit before construction is complete, the RETT on that intermediate transfer is also due at notarization (once the property is completed and title is registered), not at the point of the intermediate assignment agreement.

Several RETT exemptions are granted on conditions that must continue to be met after the transaction date. These include:

• The gift exemption: the donee must not re-dispose of the gifted property to a non-qualifying person within three years
• The in-kind contribution exemption: the shares received in exchange must be held for at least five years
• The wholly-owned group transfer exemption: ownership must remain within the same group for five years
• The merger and acquisition exemptions: continuing share/unit ownership conditions apply for five years

If any of these conditions are violated after the original transaction was granted an exemption, RETT becomes immediately due — from the date of the original transaction, not from the date of the breach. The full RETT amount that would have been due on the original transaction is retrospectively triggered.

The transferor must submit a correction request to ZATCA within 30 days of becoming aware of the breach, and pay the RETT within 30 days of the breach date. Failing to do so adds penalty exposure on top of the principal RETT amount.

RETT is charged at 5% — but 5% of what, exactly? The answer matters more than it might appear, because the base for RETT calculation is not simply whatever number the parties write into their sale agreement.

Under Article 2(c) of the Implementing Regulations, the RETT base is the total value of the real estate transaction, defined as the value of any consideration — whether cash or in kind — agreed in connection with the transaction. This is the agreed price, whenever that is within the limits of fair market value.

That qualifier is the key. Fair market value (FMV) is a floor, not a ceiling. If the agreed price equals or exceeds FMV, the agreed price is the RETT base. If the agreed price is below FMV — or if there is no cash consideration at all, as in a gift or contribution in kind — ZATCA will assess the transaction at FMV.

FMV is defined in ZATCA’s Detailed Guideline as the value that would be agreed between unrelated, independent parties dealing at arm’s length in ordinary business conditions, taking into account the nature of the transaction and the actual ownership transfer date. This is a market-referenced, objective standard — not the book value of the property, not the historic acquisition cost, and not the parties’ subjective valuation.

The RETT base is broad. Article 2(d) of the Implementing Regulations confirms that the following are treated as part of the total real estate value:

• The real estate itself — land, buildings, structures permanently attached to land
• Primary real rights — ownership rights and similar primary rights in rem directly linked to the real estate
• Secondary (accessory) real rights — rights inseparable from the primary right, such as easements, access rights, and servitudes linked to the real estate
• Permits and licences inseparable from the real estate — where a permit is closely linked to and inseparable from the real estate, it forms part of the transaction value (e.g., a development permit for a specific plot)
• Movable property intended for permanent service of the real estate — under Article 2(b), movable property placed by the owner within their real estate, intended for the permanent service or exploitation of that real estate, is treated as real estate even if not physically affixed

The last point — movable property — deserves attention. Permanently installed machinery in a factory, built-in plant and equipment, fitted-out retail fixtures, and agricultural equipment integral to a farm property could all be captured in the RETT base if they were placed in the property by the owner for its permanent service. Whether a specific asset falls into this category depends on the facts, and ZATCA has the power to include such assets in its own value assessment.

The Regulations carve out one important exclusion: the implicit profit margin in Islamic finance transactions. Specifically, for Murabaha and Ijara contracts entered into for the purpose of ownership or finance leasing, the transaction is taxable only once (on the first transfer from the original owner to the licensed financing entity), and the profit margin built into the financing arrangement is not treated as additional RETT base (Article 2(l) of the Regulations).

This is a practical relief for Islamic finance. Without it, buyers financing property through Murabaha (where the bank buys the property then sells it to the buyer at a mark-up) would face RETT on the full Murabaha price including the bank’s profit. The Regulations treat the underlying property value — not the Murabaha gross consideration — as the taxable base, subject to meeting the conditions specified in Article 2(l).

Beyond this specific carve-out, the following items are generally not part of the RETT base:

• Movable property genuinely separate from the real estate — furniture, non-installed equipment, inventory, vehicles
• Service charges or ongoing contractual obligations (e.g., maintenance contracts) that are separate from the real estate transfer itself
• VAT charged on construction services — these are a separate tax base under a different regime

The key risk is where parties attempt to strip value out of the real estate component by allocating it to movable assets or non-real-estate elements. ZATCA has explicit authority under Article 8 of the Regulations to verify values and reapportion in cases where the allocation between real estate and other assets appears artificial or unsupported.

The Regulations set out specific valuation rules for transactions that do not follow the standard sale model:

Share Transfers in Real Estate Companies

Where the transaction involves the transfer of shares or interests in a real estate company (triggering RETT through the look-through rule), the RETT base is the fair market value of all real estate owned directly or indirectly by the company, multiplied by the percentage of the shares transferred — or the value agreed between the parties and allocated to the real estate, whichever is higher (Article 2(e) of the Regulations).

This means a buyer paying SAR 100 million for a 40% stake in a company whose real estate portfolio is worth SAR 200 million would face RETT on SAR 80 million (40% × SAR 200 million FMV) — not on the SAR 100 million deal price, unless the parties’ allocation to real estate is higher.

Long-Term Usufruct Rights (Over 50 Years)

Where RETT is triggered by the grant of a usufruct right exceeding 50 years, the RETT base is the higher of: (a) the present value of the FMV of the right to use on the disposal date, or (b) the present value of the total consideration agreed (Article 2(f) of the Regulations). If the consideration is amended after the disposal date, a correction request must be submitted if the recalculation results in a change to the tax due.

BOOT Projects

For Build-Own-Operate-Transfer projects, the RETT base is the FMV of the real estate on the date of actual transfer of ownership to the transferee — being the date on which all conditions for the transfer are met under the BOOT contract (Article 2(g) of the Regulations).

Commercial real estate deals frequently bundle real estate with other assets — operating businesses, equipment, goodwill, contracts, and licences. Getting the apportionment right is not just a tax issue; it determines the RETT base and therefore the amount due.

ZATCA’s approach is to apply RETT to the real estate component of any mixed transaction. The challenge lies in proving that the non-real estate allocation is genuine, supportable, and not a mechanism for deflating the RETT base. A well-documented apportionment — with independent valuations separating real estate from other assets — provides the best protection against a ZATCA reassessment.

Article 8 of the Implementing Regulations gives ZATCA explicit authority to verify and potentially reassess the transaction value in a range of circumstances. These include:

• Transactions between related persons — where parties may have motivation to artificially set the price
• Transactions where consideration is divided between real estate and other assets — the allocation between components is a common area of scrutiny
• Cases involving non-cash consideration — barter transactions, in-kind contributions, and similar arrangements
• Transactions with an unknown or unspecified value
• Real estate transactions that are not notarized or not disclosed to ZATCA
• Cases where ZATCA suspects manipulation of value for any purpose, including tax avoidance

When ZATCA exercises this verification power, it must first give the transferor (or transferee) the opportunity to submit an assessment by an accredited assessor. ZATCA can then accept or reject that assessment. If ZATCA concludes the value is below FMV, it may use approved real estate market indicators or engage its own accredited assessor.

ZATCA can demand the additional RETT due — on the gap between the declared value and the assessed value — within three years of the disclosed transaction date (or three years from the date ZATCA became aware of an undisclosed transaction).

RETT liability in Saudi Arabia is clear on one thing: the transferor — the person disposing of the real estate — is primarily responsible for paying RETT to ZATCA. This is grounded in Article 7 of the RETT Law and the Implementing Regulations. There is no ambiguity in the statute, and ZATCA’s administrative practice reflects it consistently.

In a standard property sale, the transferor is the seller. In a gift, it is the donor. In a corporate restructuring, it is the entity or individual transferring the real estate. In a court-ordered disposal, it is the party whose asset is being transferred. The nature of the transaction does not change the fundamental rule: the person giving up the real estate bears the RETT obligation.

This has a practical implication that catches many parties off guard. RETT is a cost of disposal, not a cost of acquisition. Sellers — including corporate sellers and developers — must factor the 5% RETT cost into their transaction pricing from the outset. It comes off the proceeds, not from a cost the buyer separately settles with the government.

Under Article 11(a) of the Implementing Regulations, the transferor must also be the one to register the transaction on ZATCA’s electronic portal, generate the payment invoice, and settle it. The notarization process cannot proceed until this is done.

Commercial practice frequently results in the parties agreeing, in the sale and purchase agreement, that the buyer will bear the cost of RETT. This is entirely permissible as a contractual arrangement between them. In Saudi Arabia’s real estate market, especially in developer sales of residential units, passing RETT to the buyer is common.

Here is what that agreement does and does not achieve:

• What it does: Creates a contractual obligation on the buyer to reimburse or pay RETT as between the two parties. The seller can build the transaction price to reflect a “net of RETT” or a “RETT-inclusive” structure depending on the commercial agreement.
• What it does not do: Transfer the legal obligation to ZATCA. ZATCA looks to the transferor as the responsible party. The agreement between buyer and seller is invisible to ZATCA. If RETT is not paid, ZATCA will pursue the transferor — not the buyer — as the default obligated party.

This is a risk that sellers in particular must manage. If you sell a property, agree that the buyer bears RETT, the buyer fails to pay, and the deal completes — you have a contractual claim against the buyer, but ZATCA has a tax claim against you. Those are two different exposures on entirely different timelines and with different enforcement mechanisms.

The transferee is not completely off the hook. Under Article 7(B) of the Implementing Regulations, the transferee becomes jointly and severally liable with the transferor where ZATCA determines the transferee was the cause of the failure to pay RETT. This includes:

• Cases where the transferor and transferee made arrangements aimed at reducing the amount of RETT due or delaying payment
• Cases where the transferee committed any act that led to a violation of the exemption conditions, resulting in non-payment or underpayment of RETT

Joint liability is triggered by ZATCA’s finding of causal involvement — it is not automatic. ZATCA must notify both parties of the tax amount and payment date when it determines joint liability applies. The transferee who actually pays the tax (under joint liability) must notify ZATCA of that payment.

This provision is particularly relevant in structured transactions or corporate deals where the parties engineer an arrangement to minimise RETT exposure. If that structure is found to lack commercial substance or to be designed primarily to avoid RETT, both parties face exposure — not just the transferor.

Corporate and institutional real estate transactions involve additional considerations around who actually discharges the RETT obligation. The Regulations permit any person — not just the transferor — to make the RETT payment (Article 7(A)(1)). This means a holding entity can settle RETT on behalf of a subsidiary, or a transaction sponsor can fund the RETT obligation on behalf of the seller entity.

However, the legal responsibility remains with the transferor. Third-party payment does not change the identity of the primary obligor. If the third-party payment is later unwound or challenged, the RETT liability reverts to the transferor.

In M&A transactions involving real estate, the allocation of RETT in the SPA requires careful drafting. Common structures include:

• Seller-bears-RETT: The stated transaction price is a gross amount, and the seller settles RETT from proceeds. The buyer pays the full price regardless. Clean and simple.
• Buyer-bears-RETT: The stated price is “net of RETT.” The buyer pays the net price plus SAR X in RETT — but the seller must ensure RETT is actually settled before notarization can proceed.
• Escrow arrangement: RETT amount is escrowed at exchange and released to ZATCA at completion. Used in larger transactions where the parties want certainty that RETT will be settled before title passes.

In real estate company share deals — where RETT is triggered by the transfer of 30% or more of interests in a real estate-holding entity — the 30-day payment window from the transfer date (or unconditional agreement date, whichever is earlier) applies. The transferor of the shares is responsible for registering and paying RETT within that window.

Payment mechanics matter in practice. Under Article 7(A) of the Implementing Regulations:

1. The transferor (or their representative) registers the transaction on ZATCA’s electronic portal at zatca.gov.sa
2. The portal generates the RETT payment invoice with a unique transaction reference number and the calculated RETT amount
3. Payment is made to ZATCA’s designated bank account, referencing the unique transaction number
4. ZATCA confirms receipt and issues a registration confirmation notice
5. The confirmation notice is presented to the Notary Public, who will not proceed without it

For standard notarized property sales, the full sequence must be completed before the notary appointment. The notary serves as a gatekeeper: no RETT confirmation, no title transfer. This mechanism virtually eliminates the risk of RETT non-payment on notarized transactions.

For non-notarized transactions (share transfers in real estate companies, usufruct grants, BOOT project completions), the payment timeline is different — 30 days from the relevant trigger date — and requires proactive compliance without the notary enforcement backstop.

On 4 October 2020, Saudi Arabia made a significant structural shift in how it taxes real property. VAT — which had been applying at 5% to qualifying real estate disposals — was replaced entirely for transfer transactions by a dedicated regime: the Real Estate Transaction Tax, or RETT. The rate stayed at 5%. The regime, however, became something quite different.

RETT is not a tax on income. It is not a tax on profit. It is a tax on the act of transfer itself — imposed the moment real estate moves from one person to another, regardless of whether the transferor made any gain, whether the property is residential or commercial, and whether the transfer happens by sale, gift, court order, or corporate restructuring.

That distinction matters. A developer selling a completed villa at a loss still owes RETT at 5% of the transaction value. A family gifting property to a child may or may not be exempt — the rules are specific, and the exemption is not automatic. Getting this wrong has real financial consequences, and ZATCA has the authority to assess, investigate, and penalise non-compliance going back three years.

The regime was overhauled further when Royal Decree No. M/84 (the new RETT Law) entered force on 10 April 2025, accompanied by the Implementing Regulations issued under ZATCA Board Resolution No. 01-03-25 (24 March 2025). This article is based on the current regime as it stands under those instruments.

RETT is governed by two primary instruments:

• Royal Decree No. M/84 — the RETT Law, approved on 19 Rabi Al-Awwal 1446 H and effective from 12 Rabi Al-Thani 1446 H (10 April 2025). This is the foundational statute.
• ZATCA Board Resolution No. 01-03-25 — the Implementing Regulations, dated 24 Ramadan 1446 H (24 March 2025), which entered force simultaneously with the Law. These regulations flesh out the mechanics: how to calculate the tax, which exemptions apply and under what conditions, how and when to file, and what records must be kept.

ZATCA administers the regime under its mandate as the Kingdom’s tax and customs authority. It collects RETT, operates the electronic registration portal, conducts examinations of real estate transactions, and issues assessments where it determines the declared value understates the fair market value.

ZATCA also publishes a Detailed Guideline (currently Version 6, May 2026) that clarifies how the Law and Regulations apply to specific transaction types. Where the Guideline reflects a settled ZATCA position, it is authoritative in practice — though the Law and Regulations take precedence in any conflict.

The RETT Law applies to real estate situated in the Kingdom of Saudi Arabia. The definition is broad and includes:

• Land — any specific land area over which rights of ownership, possession, or other real rights may arise
• Everything built or constructed on land — buildings, engineering structures permanently erected on land
• Fixtures and equipment forming a fixed part of, or permanently attached to, a building or engineering structure
• Subdivided or undivided portions of real estate (an undivided interest in a jointly owned property is real estate for RETT purposes)
• Residential units, commercial units, and industrial properties
• Off-plan units — the fact that a building is not yet constructed does not remove it from the RETT scope

There is an important extension for movable property. Under Article 2(b) of the Implementing Regulations, movable property placed by its owner within real estate they own is treated as real estate if it is intended for the permanent service or exploitation of that real estate — even if it is not physically affixed. Think of permanently installed industrial machinery, built-in fixtures, or specialist agricultural equipment. These are included in the RETT base unless they can be genuinely separated from the real estate transaction.

Permits, primary and secondary rights in rem, and similar rights that are inseparable from the real estate are also treated as part of the real estate for RETT valuation purposes (Article 2(d) of the Regulations).

RETT applies to every person — individual or legal entity — who transfers real estate situated in the Kingdom. Nationality, residency, and domicile are irrelevant. A foreign company transferring Saudi real estate is subject to RETT on the same terms as a Saudi national.

The party primarily responsible for paying RETT is the transferor — the person making the disposal. This is the seller in a standard sale, the donor in a gift transaction, the distributing entity in a corporate restructuring. The obligation to pay sits with the person giving up the real estate.

The transferee (buyer or recipient) is not primarily liable — but can become jointly and severally liable if ZATCA determines the transferee was causally involved in the failure to pay. This matters in deals where the parties contractually agree that the buyer will bear RETT: that arrangement is valid between them, but it does not transfer the legal obligation to ZATCA.

RETT applies regardless of:

• The form of the transaction — sale, gift, barter, judicial order, inheritance distribution, or corporate transfer
• Whether the real estate is completed, under construction, or off-plan
• Whether the transaction is notarized or not
• Whether the real estate is residential, commercial, industrial, or undeveloped land
• Whether the transferor is a business or an individual

RETT is charged at 5% of the total value of the real estate transaction (Article 2(a) of the Implementing Regulations). That value is the consideration agreed between the parties, subject to a floor of the fair market value (FMV) at the date of the transaction.

If the agreed price is at or above FMV, the agreed price is the RETT base. If the agreed price is below FMV — or if there is no cash consideration (as in a gift) — ZATCA will assess the transaction at FMV. The concept of FMV for this purpose means the value that would be agreed between unrelated independent parties in ordinary business conditions, having regard to the nature of the transaction and the actual ownership transfer date.

The rate is flat. There is no progressive structure, no minimum de minimis threshold, and no distinction between residential and commercial property. Whether the transaction is SAR 500,000 or SAR 500 million, the rate is 5%.

One practical point worth noting: RETT is a transaction cost, not a capital gains tax. The SAR 140,000 is due whether Khalid made a profit on the sale or sold at a loss. The RETT obligation arises from the transfer event itself.

This is where many participants in Saudi real estate transactions go wrong. RETT and VAT are mutually exclusive on real estate transfers. A transaction that is subject to RETT is exempt from VAT. A transaction that falls outside the RETT scope — or is exempt from RETT — may attract VAT instead.

The key practical distinctions:

The most important rule is this: RETT applies to the disposal of real estate ownership. VAT applies to real estate services (leasing, construction, property management). When someone transfers ownership — regardless of whether it’s residential, commercial, or industrial — that is a RETT event, not a VAT event.

Developers in particular need to understand this boundary carefully. When a developer sells completed units to buyers, RETT applies to each sale. The developer’s construction costs, however, will include VAT charged by contractors — input VAT that the developer cannot recover against the RETT-exempt sale proceeds. This is a real cost issue that affects project economics.

The April 2025 Law replaced the original 2020 regime (which operated under Ministerial Resolution No. 712 of 15 Safar 1442H). The new Law and Implementing Regulations introduced several material changes:

• Expanded exemptions list: The new Law contains a significantly more detailed set of exemptions — including new provisions for off-plan developer acquisitions, endowment-owned entities, 90-day rescission of notarized transactions, and temporary guarantee arrangements under licensed financing.
• Clearer rules on Real Estate Companies: The new Regulations codify the look-through rule for transfers of interests in real estate-holding entities, with specific thresholds (50% asset test for company classification, 30% interest transfer threshold for triggering RETT) and a three-year aggregation window.
• Detailed due date rules: Article 4 of the Regulations specifies the RETT due date for each category of non-standard transaction — BOOT projects, usufruct rights, share transfers, off-plan sales — which the original regime handled less precisely.
• Expanded ZATCA enforcement powers: The new Law and Regulations strengthen ZATCA’s audit and assessment powers, including a three-year look-back window for assessments and broader provisions on deceptive transactions.
• Voluntary Disclosure mechanism: A formal voluntary disclosure framework is referenced, providing a pathway for taxpayers to correct past non-compliance with reduced penalty exposure.

RETT in Saudi Arabia is administered entirely through ZATCA’s electronic portal at zatca.gov.sa. There is no paper filing system. Every real estate transaction — whether taxable or exempt — must be registered through the portal by the transferor (or their representative) before the transaction can be completed.

The registration process captures:

• Details of the transferor and transferee (identity information)
• The deed or contract reference number
• Description and details of the real estate at the time of disposal
• Whether the transaction is taxable or exempt (and the applicable exemption basis, if exempt)
• The agreed transaction value

For taxable transactions, the portal generates a RETT payment invoice at 5% of the declared value. That invoice must be paid — via the bank account specified by ZATCA, using the unique transaction reference number — before the Notary Public or Accredited Notary will complete the title transfer. The notary will not proceed without confirmation of payment.

For exempt transactions, ZATCA issues a confirmation notice. That notice is the evidence of exemption registration and must be retained in the transferor’s records for at least five years from the transaction date (Article 11(f)(3) of the Regulations).

The transferor bears full responsibility for the accuracy of the registration. The act of registration constitutes an acknowledgment of the information provided.

RETT documentation — the Law, the Implementing Regulations, and ZATCA’s Detailed Guideline — uses precise legal and Islamic finance terminology that is not always immediately clear to practitioners working across multiple jurisdictions or disciplines. A misunderstood term can mean a misfiled transaction, an incorrectly applied exemption, or an unrecognised liability.

This glossary defines the key terms used in the RETT regime, sourced directly from Royal Decree M/84, ZATCA Board Resolution 01-03-25 (the Implementing Regulations), and ZATCA’s Detailed Guideline (Version 6, May 2026). Where a term has a specific statutory definition, that definition governs — and this glossary reflects it. Where a term is a general concept applied in the RETT context, a practical explanation is provided.
