The RETT Tax Due Date: When Does RETT Become Payable?

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.
