Capital Assets Adjustment: The Six-Year Scheme Explained

Capital assets are not consumed in a single period — they are used over years. Saudi VAT law recognises this and requires businesses to monitor how those assets are used throughout a defined adjustment period, making corrections if the use changes.

Article 52 of the VAT Implementing Regulations establishes the capital assets adjustment scheme. It is one of the most technically complex areas of Saudi VAT — but also one of the most commonly misunderstood. Businesses that buy machinery, fit out office space, or invest in significant equipment need to understand that the Input Tax position on those assets is not fixed at the point of purchase. It can change — and must be reported annually — for up to six years for most assets, and ten years for real estate.

Ordinary business costs — professional fees, utilities, consumables — are incurred and consumed within the same period or shortly after. The VAT position is settled when the invoice is processed. Capital assets are different: a machine purchased in 2024 might still be in active use in 2030 or beyond, serving whatever activity the business undertakes over that entire period.

If the business’s VAT position changes during the life of the asset — for example, it moves from fully taxable to partially exempt activities — the original Input Tax deduction may no longer reflect reality. The capital assets adjustment scheme corrects for this on an ongoing basis, ensuring that the Input Tax recovery across the life of the asset matches actual use, not just intended use at the point of purchase.

The adjustment period runs from the date of purchase of the capital asset. If the accounting life of the asset — as determined by the business’s depreciation policy — is shorter than the applicable adjustment period, the accounting life is used instead, with any partial year counting as a full year.

At the time of acquisition, Input Tax is initially deducted based on the intended use of the asset. This initial deduction sets the baseline. At the end of each 12-month period within the adjustment window, the business must compare its actual use of the asset against that original intended use and calculate whether an adjustment is required.

The annual adjustment is calculated using a fraction:

If there is no change in use from the initial intended use in a given year, no adjustment is required for that year. The obligation to adjust arises only when actual use differs from intended use.

Sale or Disposal

When a capital asset within its adjustment period is sold or permanently disposed of, the entire remaining adjustment period is settled in the VAT return for the period of disposal. The remaining Input Tax position (all future annual slices) is adjusted in that single return rather than spread across future years. This creates a one-off Input Tax adjustment at the point of sale.

No adjustment is needed if the asset is destroyed, stolen, or reaches the end of its useful life before the end of the adjustment period.

Asset No Longer Used for Taxable Activities

Where a capital asset is no longer used for taxable activities — but the business retains the asset rather than selling it — the treatment is different. No Input Tax adjustment is made for the remaining adjustment period. Instead, the business is treated as making a deemed supply of the asset, calculated using the formula involving remaining useful life and the initial recovery percentage. The result is output VAT becoming due on that deemed supply.

When a business incurs capital expenditure on an asset it already owns — for construction, enhancement, or improvement — that expenditure is treated as additional acquisition cost. A fresh adjustment period commences from the date of completion of the works.

This means a business that refurbishes a building in its 8th year of ownership triggers a new 10-year adjustment period on the refurbishment expenditure — separate from and running concurrently with whatever remains of the original building’s adjustment period. Both must be tracked independently.

• Failing to track capital assets within their adjustment period. The annual review obligation exists for every capital asset within its adjustment window. Businesses with large asset bases need a systematic tracking process — not ad hoc reviews.
• Missing the year-end adjustment in the final return. The adjustment is made in the final VAT return of the 12-month period. Filing it in the wrong period is a technical error that ZATCA can identify on audit.
• Not opening a new adjustment period after CAPEX. Enhancement or improvement expenditure on existing assets resets the clock on that CAPEX. Treating it as having no ongoing adjustment obligation is incorrect.
• Disposing of assets within the adjustment period without settling the remaining Input Tax. The disposal adjustment must be calculated and reported in the period of sale — it does not carry forward.
