UAE VAT Changes 2026: What SMEs Need to Know

UAE VAT amendments from 1 January 2026: reverse charge without self-invoices, five-year refund limit, supplier due diligence and the 31 December 2026 deadline.

The UAE VAT Law was amended with effect from 1 January 2026 through Federal Decree-Law No. 16 of 2025. The changes are not a new tax, and the standard rate has not changed. They do, however, affect how businesses document reverse-charge purchases, how long they can wait before claiming a VAT refund and how carefully they need to check their suppliers. This guide explains the main points in plain language and turns them into a practical action list for finance teams.

1. Reverse charge no longer requires a self-invoice

When a UAE business imports services or certain goods and accounts for VAT under the reverse-charge mechanism, it previously had to issue a self-invoice. Under the amended law, that self-invoicing requirement has been removed. Instead, the business must keep the supplier's invoice and the relevant supporting documents, such as import or customs records.

What to do: Stop generating internal self-invoices for new reverse-charge transactions if your adviser confirms this for your case, and make sure the original supplier invoice is attached to the purchase record. In RQM Books you can record the supplier bill and keep the supporting document beside it using the Document Management System, so the evidence is available when the VAT return is prepared.

2. A five-year limit for VAT refund claims

The amendments introduce a five-year window to claim excess recoverable input tax. The period is counted from the end of the tax period in which the excess credit arose. If a business does not request a refund within that window, the credit may no longer be recoverable.

Businesses carrying older credits should pay attention to the transitional rule: widely reported guidance on the amendment gives taxpayers until 31 December 2026 to act on older accumulated credits that would otherwise fall outside the new limit. Check the exact position of your credits with the Federal Tax Authority's current guidance or your tax agent before that date.

What to do: Review your VAT return history now. Identify any excess credit that has been carried forward for several periods and decide, with your adviser, whether a refund request should be made before the deadline.

3. Input tax can be denied where a supply is linked to evasion

The Federal Tax Authority may deny input tax recovery where a supply formed part of a tax-evasion arrangement and the buyer knew, or should reasonably have known, about it. In practice, this raises the importance of supplier due diligence. Paying the VAT to a supplier is no longer enough on its own; you should be able to show that you took reasonable steps to confirm the supplier and the transaction were genuine.

What to do:

Verify the Tax Registration Number of new suppliers and keep evidence of the check.

Be cautious about unusual pricing, payment instructions to third parties or suppliers who cannot provide delivery evidence.

Match supplier bills to purchase orders and goods received before posting them.

RQM Books links purchase orders, supplier bills and payments made, which helps the team show a clear trail from order to payment for each supplier.

4. Audit time limits now sit in the Tax Procedures Law

Time limits for VAT audits and assessments have been aligned with the Tax Procedures Law. The general limitation period is five years, with longer periods possible in specific cases such as tax evasion. The practical message is unchanged: keep complete, organised records and do not dispose of support too early.

5. Penalties have been realigned

Alongside the law changes, the UAE has been harmonising administrative penalties across VAT, excise tax and corporate tax, including a late-payment penalty expressed as an annual rate charged monthly. Because penalty schedules are set by Cabinet Decision and can change, always check the latest table published by the Federal Tax Authority before estimating any exposure.

6. The changes prepare the ground for e-invoicing

The amendments also update VAT definitions to support the UAE's electronic invoicing system, which becomes mandatory in phases from 2027. If your business will be in scope, now is a good time to clean customer and supplier master data, standardise tax codes and tighten your credit-note process. Our UAE e-invoicing readiness guide covers this in detail.
