Input VAT Recovery in the UAE: The Time Limit You Can't Miss

Recovering input VAT — the VAT you pay on your business purchases — is one of the main benefits of being VAT-registered. But it is not open-ended: UAE rules tie recovery to specific conditions and to a defined window of tax periods. Businesses that assume they can reclaim old VAT "whenever they get around to it" can find the right has lapsed, turning recoverable tax into a real cost. This guide explains the conditions to recover input VAT, the time limit for claiming it, the six-month payment rule, what is blocked, and what to do if you miss the deadline.

What is input VAT recovery?

Input VAT is the 5% VAT you are charged on goods and services you buy for your business. When you file your VAT return, you offset the recoverable input VAT against the output VAT you charged on sales, and pay only the difference. Recovering input VAT correctly is what stops VAT from becoming a cost to your business — but you only get to recover it where the conditions are met, and within the time the rules allow.

The conditions to recover input VAT

Before timing even comes into play, a cost has to qualify. You can generally recover input VAT where:

• You are a taxable person — registered for VAT and recovering tax on your own business purchases.
• The purchase is used, or intended to be used, to make taxable supplies — not exempt activities or non-business use.
• You hold a valid tax invoice showing the VAT, in the form the rules require.
• You have paid the consideration, or intend to make payment, within six months of the agreed date of payment.
• The cost is not on the blocked list (covered below).

The time limit: which tax period?

This is where businesses slip. Input VAT is not recovered "any time after you paid it" — it belongs to a specific tax period. The rule is that input tax should be recovered in the first tax period in which both of these are true: you have received the tax invoice, and you have formed the intention to pay it within six months of the agreed payment date.

If you do not recover it in that first eligible period, the rules give you one more chance: you may recover it in the immediately following tax period. Together that gives you a two-period window to claim through the normal return.

The six-month payment rule

Recovery is linked to actually paying your supplier. You can recover input VAT based on an intention to pay within six months of the agreed payment date — but if that payment is not made within six months, you must reverse the input VAT you recovered. Once you do pay, you can recover it again. In practice this means unpaid supplier invoices need watching: input VAT claimed on them is not yours to keep until the bill is settled.

Input VAT that is blocked entirely

Some input VAT cannot be recovered at all, no matter how good your paperwork or timing. The main blocked categories are:

• Certain entertainment expenses — particularly hospitality provided to people who are not employees, such as customers or suppliers.
• Motor vehicles that are available for personal use — VAT on the purchase, lease, or running of a car that can be used privately is generally blocked.
• Goods and services bought for an employee's personal benefit, outside the limited exceptions allowed by the rules.

Because these are blocked at source, the timing rules never help — the VAT was never recoverable in the first place. Knowing the blocked list prevents you from claiming tax you are not entitled to, which is itself a source of penalties.

How to stay within the window

The practical answer is disciplined monthly bookkeeping. If purchase invoices are captured as they arrive, the VAT is recovered in the period it belongs to, and unpaid invoices are tracked against the six-month rule, the time limit looks after itself. The businesses that lose recovery are almost always the ones that let paperwork pile up and reconcile late — by which point the eligible periods may already have passed.

Input VAT recovery is valuable, but it is governed by conditions and a window that are easy to miss when records run behind. If you would like your input VAT recovered correctly and on time — and old periods cleaned up where needed — our team can take it on.

A second clock, and a new condition — both from 2026

Everything above concerns when a recoverable amount must be claimed in a return. Two changes taking effect in 2026 sit alongside it, and neither replaces what this page describes.

The first is a limit on the credit balance itself. Federal Decree-Law No. 16 of 2025, in force from 1 January 2026, introduces a five-year time limit for submitting a request to reclaim excess refundable tax after reconciliation. The Ministry of Finance's wording is that once the period elapses, the right to reclaim the tax expires. Article 74 previously carried an unclaimed excess forward to subsequent Tax Periods with no end date. A business sitting on a credit balance now has a dated position rather than an open one.

The second is a condition on the deduction. The same Decree-Law added Article 54 bis, which allows the Authority to deny an input tax deduction where the supply forms part of a tax-evasion arrangement. FTA Decision No. 13 of 2026 implements it from 1 October 2026 and sets out what a Taxable Person must do before deducting — verifying the supplier's identity, place of business and risk indicators, and verifying each supply — together with a documented policy naming who runs those checks.
