The UAE VAT Refund 5-Year Rule
A five-year limit now applies to reclaiming excess refundable VAT under the UAE's 2026 VAT-law amendments, measured from the end of the relevant tax period rather than from when you first noticed the credit. In practice this means excess VAT credits dating back to 2021 begin expiring during 2026 — if you have been carrying forward a refundable balance instead of actively claiming it, part of that money can be lost permanently. A transitional window allows older balances, including pre-2022 credits, to still be claimed until 31 December 2026; after that date, unclaimed excess input VAT is gone for good. Businesses carrying any credit balance should age it now, prioritise the oldest portions, and file before the transitional deadline rather than after.

How the limit is measured
The clock runs from the end of the tax period the credit relates to, not from the date you filed the return or the date you actually noticed the balance. This distinction matters because it means the countdown has already been running quietly in the background for years on older credits — a 2021 balance is not measured from 2026, it is measured from whenever that specific 2021 tax period ended, which is exactly why those amounts are the ones now approaching expiry. Older credits, including pre-2022 balances built up before the rule existed, are the most at risk precisely because they have had the least warning.
- Excess refundable tax must be reclaimed within five years.
- The window is measured from the end of the relevant tax period.
- The date you notice or file does not reset the clock.
- Older credits, including pre-2022 balances, are most at risk.
- A transitional route allows claims up to 31 December 2026.
- Each tax period's credit has its own five-year deadline.
Act on the oldest credits now
Carrying a balance forward indefinitely was always administratively convenient, but it is no longer safe under the five-year limit. The first step is establishing exactly how old each portion of your credit balance is, since a single lump-sum figure on EmaraTax can actually be made up of several tax periods with different expiry dates. From there, prioritise claiming 2021 and pre-2022 amounts first, keep documentation clean given the FTA's tighter scrutiny of input-tax claims, and set an internal reminder well ahead of 31 December 2026 rather than at the deadline itself, since claims filed at the last moment leave no time to fix a query.
- Identify how old each portion of your credit balance is.
- Prioritise claiming 2021 and pre-2022 amounts first.
- Keep documentation clean given tighter input-tax scrutiny.
- Set an internal reminder well ahead of 31 December 2026.
- Do not wait until the deadline month to file.
- Review the balance every filing period, not just once a year.
What is actually at risk
Take a zero-rated exporter with AED 2,000 in output VAT against AED 42,000 in recoverable input VAT for a 2021 tax period — a AED 40,000 refundable credit. If that business simply let the balance carry forward on EmaraTax without ever filing a refund request, the five-year clock on that specific AED 40,000 has been running since the end of the 2021 period, and it is exactly this kind of untouched, ageing balance that starts falling outside the window during 2026. The transitional deadline of 31 December 2026 is the last practical chance to claim it before it is lost.
- AED 40,000 refundable from a single 2021 period, in this example.
- The five-year clock started at the end of that 2021 period.
- Untouched, carried-forward balances are the ones most exposed.
- 31 December 2026 is the last transitional chance to claim older amounts.
Ageing your credit balance before it expires
Exiloz reviews your full VAT account history and breaks the total credit balance down by the tax period each portion originated from, so you know precisely which amounts are closest to falling outside the five-year window rather than relying on a single lump-sum figure. Where older, pre-2022 credits are involved, we prioritise those claims first and file them well ahead of the 31 December 2026 transitional deadline, while flagging any documentation gaps that could slow a claim down at the worst possible time.
- Full VAT account history reviewed and broken down by period.
- Oldest, most at-risk credits identified and prioritised.
- Claims filed with a safety margin before 31 December 2026.
- Documentation gaps flagged early, not discovered at the deadline.

Frequently Asked Questions
For businesses carrying forward a VAT credit balance and unsure how much of it is actually at risk.
When is the deadline to claim old VAT credits?
The transitional window closes on 31 December 2026 for older, pre-2022 balances; more generally, any excess refundable VAT must be claimed within five years of the end of the relevant tax period, whichever comes first for that specific portion.
What happens if I miss the deadline?
Unclaimed excess input VAT is lost permanently once the applicable window closes — it cannot be refunded, and in most cases it can no longer be used to offset future VAT either.
How is the five years counted?
From the end of the tax period the credit relates to, not from when you noticed it or from the date of a related return. This means the clock can already be well advanced before a business realises a balance exists.
Does the five-year rule apply to my whole credit balance at once?
No. A single balance on EmaraTax can be made up of several different tax periods, each with its own five-year deadline, so part of it can expire before the rest does.
Is the 31 December 2026 date the same for everyone?
It applies specifically as a transitional deadline for older, pre-2022 balances. Credits arising after the rule took effect are simply measured on the standard five-year basis from their own period end.
Should I claim now or wait?
If any portion of your balance is old enough to be near its five-year mark, claim it now rather than waiting — there is no benefit to delaying a claim you are already entitled to, and real downside if it expires.
Can Exiloz tell me what is at risk?
Yes. We age your credit balance by tax period, flag exactly which amounts must be claimed before they expire, and prioritise those claims ahead of the 31 December 2026 transitional deadline.
