UAE VAT Refund Deadline 2026: How the Five-Year Rule Affects Your Excess VAT Credits

August 2026 · Tax · VAT Compliance · Federal Tax Authority

For eight years, UAE businesses could treat excess input VAT as a permanent asset. If input tax exceeded output tax in a tax period, the surplus sat in the taxpayer account and could be carried forward indefinitely, offset whenever convenient or refunded whenever the business got around to it. That position ended on 1 January 2026.

Federal Decree-Law No. 16 of 2025 and Federal Decree-Law No. 17 of 2025, both issued by the Ministry of Finance on 25 November 2025, introduced a five-year statute of limitation on excess recoverable VAT and rewrote the procedural rules governing refunds, voluntary disclosures and audits. The immediate consequence for most businesses is a hard cut-off of 31 December 2026, after which historic credit balances are extinguished, not merely frozen. This article sets out what changed, which balances are at risk, how the claim is made, and the audit exposure that comes with filing late in the window.

1. What changed on 1 January 2026

Two instruments took effect on the same date and need to be read together:

• Federal Decree-Law No. 16 of 2025 amends Federal Decree-Law No. 8 of 2017 (the UAE VAT Law). It rewrites Article 74(3) on excess recoverable tax, adds three anti-evasion provisions to Article 54, simplifies Article 48(1) on the reverse charge mechanism, and repeals Article 79 bis.
• Federal Decree-Law No. 17 of 2025 amends Federal Decree-Law No. 28 of 2022 (the Tax Procedures Law). Its changes are the more extensive of the two, covering the determination of payable tax, voluntary disclosures, the refund application regime in Article 38, the statute of limitation in Article 46, and a new Article 54 bis on official FTA guidance.

Nothing in either instrument changes the VAT rate, the exemption and zero-rating categories, or the tax grouping rules. The standard rate remains 5 per cent. What has changed is the shelf life of a credit and the procedural framework the Federal Tax Authority (FTA) applies to it.

2. The five-year rule under Article 74(3)

Under the amended Article 74(3) of the VAT Law, excess recoverable input tax may be carried forward for a maximum of five years from the end of the tax period in which the excess arose. Within that window the taxpayer must do one of two things:

• use the excess to settle VAT liabilities in subsequent tax periods; or
• submit a formal request to recover it.

If neither happens before the five-year period closes, the right to claim the excess lapses. The practical significance of the wording is that the balance is not simply barred from cash refund – it can no longer be used to settle any VAT liability at all.

The clock runs per tax period, not per balance. The aggregate credit figure shown in EmaraTax is usually the sum of several vintages, each with its own expiry date. A single balance of AED 400,000 may contain 2019, 2021 and 2023 credits that lapse in three different years. Any review has to start with an aging analysis by originating tax period, not with the headline number.

Article 79 bis of the VAT Law, which previously housed VAT-specific limitation provisions, has been repealed. Limitation is now governed principally by the Tax Procedures Law, which is why the two decree-laws have to be read as a package.

3. The 31 December 2026 transitional window

The legislature recognised that businesses could not have planned around a rule that did not exist. Article 3 of Federal Decree-Law No. 17 of 2025 therefore contains transitional provisions. Under Article 3(1), a taxpayer entitled to a refund or credit balance whose five-year claim period had already expired at the effective date of the decree-law, or which expires within one year of that date, may still request a refund or apply the balance against tax due and administrative penalties – provided the request is submitted within one year of the effective date.

One year from 1 January 2026 gives a final date of 31 December 2026. Market commentary, including KPMG’s analysis of the amendments, reads this as giving businesses until 31 December 2026 to claim outstanding balances for the 2018 to 2020 tax years. There is no provision for an extension, and none has been announced as at August 2026.

A drafting point worth flagging on 2021 balances. On its wording, Article 3(1) also captures balances whose ordinary five-year window falls due during 2026 – which includes the 2021 tax periods. Commentary is divided: some advisers treat 2021 credits as protected until 31 December 2026, others treat them as lapsing on their ordinary rolling dates, and the FTA has not published a clarification. The prudent course is to treat the ordinary date as binding and file before it, relying on the transitional provision only as a fallback argument. A Q1 2021 credit should not be left until December on the assumption that relief applies.

Expiry map for a quarterly filer

Monthly filers follow the same logic period by period. A credit arising in the March 2021 return runs to 31 March 2026; April 2021 to 30 April 2026, and so on.

4. Making the claim: the amended Article 38

Article 38 of the Tax Procedures Law now sets out the refund application regime in detail, including what happens when a credit balance only comes into existence near or after the end of the limitation period.

In practice the request is filed through the FTA’s EmaraTax portal using the VAT refund form (VAT311). Two sequencing points matter more than they appear to:

• Errors in the underlying returns should be corrected before or alongside the refund request, not after it. A claim resting on returns the taxpayer subsequently amends is the most common cause of rejection and delay.
• Offsetting is a valid alternative to a cash refund. Applying an ageing credit against a current VAT liability also satisfies the Article 74(3) requirement and is frequently the lower-friction route where the amounts are modest.

5. Filing a claim opens an audit window

Article 46(1) of the Tax Procedures Law confirms five years as the default limitation period for tax audits and assessments, but the exceptions in clauses (4), (7) and (8) have been broadened. Two of them bear directly on refund claims:

• Article 46(4): where a taxpayer submits a refund claim in the fifth year following the end of the relevant tax period, the FTA may still audit or assess in relation to that claim. Any such audit or assessment must be completed within two years of the date the claim was submitted.
• Article 3(3) of the transitional provisions: the FTA may conduct an audit or issue an assessment in relation to a refund or credit balance application even where it falls outside the five-year limit, provided the audit or assessment is completed within two years of the application date.

A transitional claim filed in December 2026 can therefore keep the underlying periods open to FTA scrutiny into late 2028. That is not a reason to forgo the claim – it is a reason to reconstruct the supporting documentation before filing rather than after the FTA asks for it. Businesses should assemble the audit file at the point of submission and assume the periods concerned remain live.

6. Voluntary disclosures under the new framework

The voluntary disclosure regime has been eased in one respect and tightened in another. Under the amended Article 10(5), a voluntary disclosure is no longer required for every error. The FTA specifies the cases in which one must be filed; all other errors may be corrected directly through the tax return. This is a meaningful simplification for routine corrections.

Article 46(6) reaffirms the five-year limit for voluntary disclosures, with an exception for refund-related disclosures awaiting an FTA decision. Article 3(2) of the transitional provisions builds on this: a taxpayer may submit a voluntary disclosure in relation to a refund application within two years of filing that refund application, even where the ordinary five-year period has expired. Critically, this option is not available once the FTA has already issued its decision on the refund.

The sequencing consequence is straightforward. If a legacy period needs correcting, the correction must be made while the refund application is still pending. Once the decision lands, that route closes.

7. Two further amendments that affect recovery

Input tax denial where a supply is connected to tax evasion

Article 54 of the VAT Law now contains three new provisions. The FTA will disallow an input tax deduction where the supply forms part of a supply or chain of supplies connected to tax evasion and the taxpayer was aware of that connection when claiming. It may disallow the deduction where, on the circumstances of the supply, the taxpayer ought to have been aware. And a taxpayer is treated as aware where it failed to verify the validity and integrity of the supplies received before claiming the input tax.

The practical effect is that supplier due diligence has moved from good practice to a condition of recovery. This matters for historic claims as much as current ones: a substantial legacy refund request invites scrutiny of the supply chains behind it, and the burden of showing that reasonable verification was carried out sits with the taxpayer.

Reverse charge self-invoicing removed

Under the amended Article 48(1), a taxable person importing concerned goods or services for business purposes is no longer required to issue a tax invoice to itself under the reverse charge mechanism. The obligation to account for the tax is unchanged; what disappears is the self-invoice. Supporting documentation – supplier invoices, contracts, import documentation and the other records specified by the Executive Regulation – must be retained instead.

A separate deadline that is often confused with this one. Foreign businesses with no establishment in the UAE recover VAT under the Foreign Business Refund Scheme, which operates on its own annual application window rather than the five-year carry-forward rule. It is a distinct regime with a distinct deadline and is not covered by the transitional relief discussed above. Businesses claiming under that scheme should confirm the current window directly with the FTA.

8. What businesses should do before 31 December 2026

• Extract the full credit history from EmaraTax by tax period. Do not work from the aggregate balance shown on the dashboard.
• Age every credit to its originating tax period and map the ordinary five-year date for each.
• Identify which balances fall within the transitional window and diarise 31 December 2026 as a firm internal deadline, working back at least eight weeks for preparation.
• Reconcile each credit to the filed return and to the underlying tax invoices and import documentation.
• Resolve prior-period errors first, by voluntary disclosure or return correction as the FTA framework requires, and before the refund application is decided.
• Review supplier due diligence exposure under the amended Article 54 for every period being claimed.
• Decide between offset and refund for each balance. Offsetting preserves the credit and avoids the refund review process entirely.
• Build the audit file at the point of filing, on the working assumption that the periods claimed stay open for a further two years.

Frequently asked questions

What is the deadline for claiming historic UAE VAT credits?

For balances within the transitional window under Article 3(1) of Federal Decree-Law No. 17 of 2025, the deadline is 31 December 2026. For all other balances, it is five years from the end of the tax period in which the excess arose.

What happens if the deadline is missed?

The right to claim the excess lapses. The balance cannot be refunded and cannot be used to settle any future VAT liability. The legislation contains no extension mechanism.

Can a credit be offset against future VAT instead of refunded?

Yes. Using the excess to settle a VAT liability within the five-year window satisfies Article 74(3) just as a refund request does, and avoids the refund review process.

Does the rule apply to free zone and designated zone businesses?

Yes. The rule operates by reference to VAT registration and the tax period in which the excess arose, not by reference to where the business is licensed. Mainland, free zone and designated zone registrants are all affected.

Does filing a refund claim trigger an FTA audit?

Filing does not automatically trigger an audit, but it preserves the FTA’s ability to audit or assess in relation to that claim for two years from the submission date, including where the claim falls outside the ordinary five-year limit.

Does the five-year limitation apply to taxes other than VAT?

The limitation provisions sit in the Tax Procedures Law, which governs federal taxes administered by the FTA, so the procedural framework is broadly aligned across tax types. The specific carry-forward rule in Article 74(3) is a VAT Law provision and applies to VAT.

How TME Legal Can Assist

The transitional window closes once. Preparing a defensible claim takes longer than most businesses expect, particularly where the credits date back to 2018 and the records sit with a former finance team or a previous accounting provider. We support clients with:

• aging analysis of excess input VAT balances by originating tax period and mapping of each applicable deadline;
• assessment of which balances qualify under the transitional relief in Article 3 of Federal Decree-Law No. 17 of 2025;
• preparation and submission of VAT refund requests through EmaraTax, including the supporting documentation pack;
• voluntary disclosure strategy and sequencing, so corrections are made before the FTA issues its refund decision;
• review of supplier due diligence and input tax recovery exposure under the amended Article 54 of the VAT Law;
• representation before the FTA in reviews, audits, reconsideration requests and proceedings before the Tax Disputes Resolution Committee.
