If you run a VAT-registered business in the UAE, three changes to the VAT law are already live and affecting how you file, claim refunds, and document transactions. Federal Decree-Law No. 16 of 2025 came into force on 1 January 2026, and the FTA expects compliance now - not once you get around to updating your processes.
TL;DR: UAE VAT law changed on 1 January 2026. Self-invoicing for reverse charge is gone - retain supplier documents instead. VAT refund claims now expire after five years. The FTA can deny input tax if your supplier is linked to evasion. Update your records and review old credits before December 2026.
What Are the Three Key Changes?
The amendments sit inside Federal Decree-Law No. 16 of 2025, which amends the original VAT legislation (Federal Decree-Law No. 8 of 2017, as previously amended by Decree-Law No. 28 of 2022). Three changes matter for day-to-day operations:
- The reverse charge self-invoice requirement is removed
- VAT refund claims have a hard five-year deadline
- The FTA gained authority to deny input tax linked to evasion
Each one affects different parts of your VAT workflow. In our experience, the refund deadline catches the most businesses off guard - particularly those sitting on unclaimed credits from 2018 or 2019.
How Does the Reverse Charge Mechanism Work Now?
You no longer need to generate self-invoices when applying the reverse charge. Instead, retain the supplier's invoice, the contract, and any import documentation as your evidence trail.
This applies to all reverse charge scenarios: imported services, purchases from unregistered suppliers, and domestic supplies of gold or scrap metal subject to the mechanism. The Ministry of Finance described the change as one that "enhances administrative efficiency and provides clear audit evidence."
What we see most often is businesses that automated self-invoice generation in their accounting software. Those workflows need switching off or redirecting. If your system still generates self-invoices, you are creating documents that no longer have legal standing under the amended law.
What to retain instead
For each reverse charge transaction, keep on file:
- The original supplier invoice or customs declaration
- The contract or purchase order
- Payment records showing the transaction amount
- Your VAT return showing the output and input tax declared
When Does a VAT Refund Claim Expire?
Five years from the end of the tax period in which the excess credit arose. After that window closes, the right to claim lapses entirely - no exceptions, no extensions.
For credits accumulated between 2018 and 2020, a transitional provision applies: you must submit your refund claim by 31 December 2026 or lose those credits permanently (ClearTax UAE, 2026).
This is a material deadline. Over 651,000 businesses registered for UAE tax in 2025 (Danix Consultancy, 2025), and many early registrants from 2018 still carry unclaimed input tax on their books. If you are still getting to grips with the broader UAE corporate tax framework, the refund clock is ticking regardless. The FTA processed over AED 3.2 billion in VAT refunds for UAE nationals in 2025 alone - the demand is real and the system functions, but only if you file on time.
Who is most at risk?
Businesses registered in 2018 that:
- Carried forward input tax credits rather than requesting refunds
- Changed their supply mix (moving from exempt to taxable supplies) and accumulated credits in the transition
- Operated under the tourist refund or new-build refund schemes without claiming promptly
One question clients always ask is whether carrying a credit forward on returns counts as "claiming" it. It does not. The five-year limit applies to refund requests specifically - the formal application through the FTA portal to get money back into your bank account.
Can the FTA Deny Your Input Tax Deduction?
Yes. The amendments give the FTA explicit authority to deny input VAT recovery where a supply is connected to tax evasion and the recipient "knew or should have known" about the evasion at the time of claiming.
This creates a practical due-diligence requirement. You need documentation proving you verified your supplier's legitimacy before claiming input tax on their supplies. The FTA's 2024 Annual Report recorded 93,000 inspection visits - a 135% increase on the previous year (FTA, 2025) - and that enforcement intensity is not slowing down.
How to protect your input tax claims
High-risk sectors (electronics, gold, scrap metal trading) face the most scrutiny. If you have been through (or are preparing for) an FTA tax audit, supplier documentation is now front and centre. Any business should:
- Verify suppliers hold valid VAT registration via the FTA TRN verification tool
- Keep copies of supplier tax registration certificates on file
- Flag transactions where the supplier's pricing seems inconsistent with standard market rates
- Document your due diligence at the point of purchase, not retrospectively during an audit
What Penalties Apply for Non-Compliance?
The penalty structure remains steep. Under Cabinet Decision No. 129 of 2025, effective 14 April 2026:
- Late filing: AED 1,000 for the first offence, AED 2,000 for repeat offences within 24 months
- Late payment: 2% immediately after the due date, plus 4% if unpaid after seven days, plus 4% monthly thereafter (capped at 300% of the original fine)
- Incorrect information: AED 3,000 first offence, AED 5,000 if repeated within 24 months
- Non-registration: AED 10,000
Voluntary disclosure of errors carries a 1% monthly penalty on the tax difference from the original return due date until submission (Hallmark International Auditors, 2026).
What Should You Do This Month?
If you have not updated your VAT processes since January, these steps are overdue:
- Disable self-invoice automation in your accounting software for reverse charge transactions
- Audit your VAT credit balance - identify any credits from tax periods before 2021 and submit refund applications before 31 December 2026
- Implement supplier due diligence - at minimum, verify TRN numbers for all active suppliers and file copies of their registration certificates
- Review your VAT return filing process to ensure documentation meets the new retention standards
- Check your FTA compliance calendar - e-invoicing goes live for B2B and B2G in July 2026, adding another layer
The VAT rate stays at 5%. Registration thresholds stay at AED 375,000 (mandatory) and AED 187,500 (voluntary). Businesses that recently reduced their FTA penalty exposure should treat these amendments as the next compliance checkpoint. The mechanics of filing quarterly returns through the FTA portal remain the same. These amendments change the documentation rules, the refund window, and the FTA's enforcement powers - not the core tax calculation.
Frequently Asked Questions
Do these changes affect my VAT rate or registration threshold?
No. The standard 5% VAT rate, the AED 375,000 mandatory registration threshold, and the AED 187,500 voluntary threshold all remain unchanged. The amendments affect process and documentation, not the rate or scope of VAT itself.
Can I still carry forward excess input tax on my VAT return?
Yes, carrying forward credits on your return remains available. The five-year limit applies specifically to requesting a cash refund from the FTA. If you offset credits against future output tax within the normal return cycle, that is not affected by the new deadline.
What happens to VAT credits from 2018 if I do not claim by December 2026?
They expire. The transitional provision gives businesses until 31 December 2026 to submit refund requests for credits from 2018-2020. After that date, those credits become non-recoverable regardless of their validity.
Does the anti-evasion rule mean the FTA will investigate every supplier I use?
No. The FTA applies this power where there is evidence of a supply chain connected to evasion and the buyer "knew or should have known." Routine commercial transactions with established suppliers carry minimal risk. The rule targets situations where pricing, supply patterns, or missing-trader indicators suggest fraud.
Is the reverse charge mechanism itself being removed?
No. The reverse charge mechanism still applies to imported services, purchases from unregistered suppliers, and designated domestic supplies. The change removes the administrative requirement to self-invoice - you still account for reverse charge VAT on your return as before, but the evidence you keep is different.
