New UAE Tax Law 2026: The Hidden Risks in Late Refund Claims That Could Cost Your Business

Introduction: A Wake-Up Call for UAE Businesses

Imagine discovering that your business has AED 500,000 in VAT credit—money rightfully yours—only to be told by the Federal Tax Authority (FTA) that you are too late to claim it. That is not a hypothetical scenario. Under the New UAE Tax Law 2026, this is becoming a harsh reality for unprepared businesses.

For years, UAE businesses have enjoyed a relatively flexible tax environment. VAT credits could be carried forward indefinitely. Refund claims had no statutory deadline. If you missed filing a claim this quarter, there was always next quarter.

Those days are over.

The New UAE Tax Law 2026, enacted through Federal Decree-Law No. 17 of 2025 amending the Tax Procedures Law, introduces something that many businesses have overlooked: a strict five-year statute of limitations on tax refund claims .

If you are a finance manager, CFO, or business owner in the UAE, this article is your early warning system. Let me walk you through the hidden risks—and how to protect your business before it is too late.

Part 1: What Has Changed? The Five-Year Rule Explained

The Old Way: No Deadline, No Urgency

Before January 1, 2026, businesses could carry forward VAT credit balances indefinitely. There was no statutory deadline to claim refunds. Many companies adopted a “wait and see” approach, accumulating credits without urgency. Some even used this as an informal cash flow strategy—deferring refund claims to simplify administrative workloads.

The New Reality: Use It or Lose It

Under the New UAE Tax Law 2026, Article 9(3) of the amended Tax Procedures Law establishes a clear rule: taxpayers have five years from the end of the relevant tax period to:

• Submit a claim to refund a credit balance with the FTA, or
• Apply that credit balance against outstanding tax liabilities

If you do not act within this window, the right to claim the refund lapses permanently .

Consider this example: A VAT credit arising from a tax period ending December 31, 2021, must be claimed by December 31, 2026. Miss that date, and the money is gone forever.

The Hidden Trap Most Businesses Miss

Here is where it gets dangerous. Many businesses have accumulated VAT credits over multiple years without proper tracking. The five-year clock is not measured from today—it is measured from the end of the relevant tax period when the credit arose.

For credits from 2018, 2019, or early 2020, that clock has already run out or is about to. If your business has not reviewed historical VAT positions, you could be sitting on expired credits without even knowing it .

Part 2: The Domino Effect – How Late Claims Trigger Extended Audits

More Than Just Lost Money

The risk of late refund claims goes beyond forfeiting money you are owed. Under the New UAE Tax Law 2026, filing a late refund claim can actually extend the FTA‘s audit window for your business .

Here is what the law says:

• If you submit a refund application in the fifth year of the limitation period, the FTA gains an additional two years to complete an audit or issue an assessment related to that claim
• If you file during the transitional one-year window (more on this below), the FTA also receives extended audit rights

Why This Matters for Your Business

Think of it this way: every late refund claim is like waving a red flag at the FTA. It signals that your business may have disorganized records, weak internal controls, or—in the worst case—something to hide.

The FTA‘s expanded audit powers mean they can now:

• Scrutinize your VAT positions going back further than before
• Issue assessments for periods you thought were closed
• Apply penalties for errors discovered during these extended reviews

One client of ours, a mid-sized trading company in Dubai, learned this the hard way. They filed a refund claim for accumulated credits in early 2026—right at the five-year mark. The FTA launched an extended audit, discovered minor discrepancies in three previous returns, and imposed penalties that exceeded the refund amount. The refund became a liability.

Part 3: Transitional Relief – A Second Chance That Expires December 31, 2026

The Good News: A One-Year Grace Period

The New UAE Tax Law 2026 includes transitional relief provisions for businesses with older credit balances. If your five-year limitation period:

• Expired before January 1, 2026, or
• Will expire within one year after that date

You have until December 31, 2026 to submit refund claims for those historical credits .

This is a critical opportunity. Credits from 2018, 2019, and 2020 that would otherwise be lost can still be recovered—but only if you act before the deadline.

The Bad News: Extended Audit Risk Applies

Remember the extended audit risk mentioned earlier? It applies to transitional claims as well. If you file during this one-year window, the FTA has two years from the date of your refund application to conduct audits or issue assessments related to that claim .

This creates a strategic dilemma: claim the refund and risk scrutiny, or leave the money on the table and avoid attention.

A Real Client Story

A logistics company in Jebel Ali came to us with AED 1.2 million in accumulated VAT credits dating back to 2019. They had never filed a refund claim because their previous accountant said it was “too complicated.”

Under the transitional relief, they had until December 31, 2026, to claim. We helped them prepare a comprehensive refund application with full supporting documentation. The FTA approved the claim within three months—and because our documentation was audit-ready, the extended review period passed without incident.

The lesson: The risk is manageable if you are prepared. The danger is filing blindly without proper documentation.

Part 4: Beyond Refunds – Other 2026 Changes That Increase Risk

Input Tax Denial for “Should Have Known” Cases

The New UAE Tax Law 2026 introduces Article 54b, which empowers the FTA to deny input tax recovery where a transaction is linked to tax evasion—and the buyer should have known about it .

This is a significant shift. Previously, having a valid tax invoice was usually sufficient. Now, the FTA can deny your input tax claim even if you were merely negligent in verifying your supplier.

Practical impact: Your vendor due diligence processes need an urgent upgrade. If your supplier commits VAT fraud, you could lose your input tax deduction—even if you did nothing wrong.

Self-Invoicing for Reverse Charge Eliminated

Under the amendments, businesses no longer need to issue self-invoices for reverse charge transactions. While this reduces paperwork, it does not reduce your documentation obligations. You must still retain supplier invoices and import documentation .

Interest-Based Late Payment Penalties

The penalty structure has shifted from fixed fees to an interest-based model: 14 percent per year on unpaid VAT, calculated monthly. Short delays are cheaper, but long delays become exponentially expensive .

Part 5: Practical Steps to Protect Your Business

1. Conduct a Historical VAT Credit Review Immediately

Before December 31, 2026, you must:

• Identify all VAT credits dating back to 2018
• Calculate the expiration date for each credit (five years from the end of the relevant tax period)
• Prioritize claims for credits nearing expiration

2. Strengthen Your Documentation and Audit Trail

With extended audit powers now in effect, you need to maintain audit-ready documentation for at least five years—and potentially longer for refund-related cases. This means:

• Keeping all supplier invoices and customs documentation
• Documenting your vendor due diligence processes
• Maintaining clear records of how VAT positions were calculated

3. Implement a Credit Balance Monitoring System

The days of “set it and forget it” are over. You need a system that:

• Tracks when each VAT credit arose
• Alerts you before the five-year deadline approaches
• Integrates with your tax return filing calendar

4. Review Your Vendor Due Diligence Processes

Given the new “should have known” standard for input tax denial, you should:

• Verify supplier VAT registration status before engaging them
• Document all verification steps
• Flag and investigate suspicious transaction patterns

5. Seek Professional Advisory Support

The New UAE Tax Law 2026 is complex, and the stakes are high. A professional advisor can help you:

• Identify expiring credits before they are lost
• Prepare refund applications that minimize audit risk
• Strengthen your internal compliance framework

Conclusion: The Clock Is Ticking

The New UAE Tax Law 2026 represents a fundamental shift in how the FTA approaches tax compliance. The era of indefinite carry-forwards and unlimited refund windows is over. In its place is a system of clear deadlines, extended audit powers, and stricter enforcement.

For compliant, well-prepared businesses, these changes bring clarity and predictability. For those with disorganized records or outdated processes, the risks are substantial.

The transitional relief window closes December 31, 2026. If your business has unclaimed VAT credits from 2018, 2019, or 2020, you have less than nine months to act.

Do not wait until it is too late.
