The New UAE Tax Procedures Law: What Changed
Most UAE businesses treat compliance as a once-a-year task. Federal Decree-Law No. 17 of 2025 makes that posture risky. It rewrote the UAE Tax Procedures Law with effect from 1 January 2026, tightening deadlines, hardening the rules around tax credits, and extending how far back the Federal Tax Authority (FTA) can look. The headline change is that the FTA’s audit reach can now stretch to fifteen years.
This guide sets out what actually changed, what it means for how you keep records and manage deadlines, and the practical steps to take.
What changed in the UAE Tax Procedures Law?
Federal Decree-Law No. 17 of 2025 is the instrument that rewrote the Tax Procedures Law from 1 January 2026. Three threads run through it: tighter procedural deadlines, a hard five-year limit on recovering tax credits, and a longer audit reach.
The amended law keeps the core corporate tax filing deadline at nine months from the end of the financial year. For a business with a 31 December 2025 year-end, that means a 30 September 2026 filing and payment date. What changed is the surrounding discipline. Deadlines across the procedural framework are tighter and enforced more consistently. The era where a late filing was quietly absorbed is over.
The five-year limit on tax credits
The new law puts a hard five-year limit on recovering a credit balance. A refund request, or use of the balance to settle a liability, must happen within five years from the end of the relevant tax period. Miss that window and the balance is forfeited entirely.
This affects VAT credits most directly, and there is a transitional window closing on 31 December 2026 for older balances. We cover the detail in our piece on unclaimed VAT credits expiring in 2026. The principle to carry from here: a credit is no longer a number you can sit on indefinitely.
How far back can the FTA audit now?
This is the change that should reset how businesses think about records.
Previously, the statute of limitation for FTA audits and assessments was generally capped at five years. That gave businesses a clear window of exposure. Under Federal Decree-Law No. 17 of 2025, that period can be extended to up to fifteen years in specific circumstances, such as cases involving tax evasion or a failure to register for tax.
In practice, this means the FTA can reach much further back when something looks wrong. A business that cannot produce records from years ago is not in a strong position to defend an assessment. The five-year shredding habit no longer fits the law. The same logic applies when you are preparing for any corporate tax audit: records are the defence.
What longer reach means for record keeping
If the authority can look back fifteen years in the wrong circumstances, your records need to survive that long. That changes a few habits.
Keep your books, supporting documents, contracts and filings for the full retention period the law requires, and treat digital archives as the default rather than boxes that get cleared out. The cost of storage is trivial. The cost of an undefended assessment is not.
Clean, complete and retrievable records are the only real defence in an audit. The new reach simply raises the stakes on having them, which is the whole case for keeping clean books as a continuous habit.
What should UAE businesses do?
1. Map your filing calendar. List every corporate tax, VAT and procedural deadline that applies to you, and the penalty for missing each. Remove the guesswork.
2. Review your record retention. Confirm how long you keep books and supporting documents, and extend it to match the law. Move to durable digital archives.
3. Claim credits on a cycle. Do not let VAT or other credit balances age toward the five-year limit. Build a routine to claim or apply them.
4. Treat compliance as continuous. The shift in this law is from annual cleanup to ongoing discipline. Monthly bookkeeping and a live deadline calendar are now the baseline.
Frequently asked questions
What is Federal Decree-Law 17 of 2025?
The amendment that rewrote the UAE Tax Procedures Law from 1 January 2026, tightening deadlines, setting a five-year limit on tax credits, and extending the FTA’s audit reach.
How far back can the FTA audit a business now?
Generally five years, but extendable to up to fifteen years in specific cases such as tax evasion or failure to register.
How long must UAE businesses keep tax records?
Long enough to cover the audit reach. Keep books, documents, contracts and filings for the full required period and use durable digital archives rather than clearing records after five years.
What is the five-year limit on tax credits?
A refund or use of a credit balance must happen within five years of the end of the relevant tax period, or the balance is forfeited. A transitional window closes 31 December 2026.
When did the new Tax Procedures Law take effect?
On 1 January 2026. The nine-month corporate tax filing deadline stays, but procedural deadlines are tighter and enforced more consistently.
The new Tax Procedures Law does not change what an honest business owes. It changes how long it must be able to prove it, and how quickly a slip becomes a penalty. The businesses that keep clean, durable records and a live deadline calendar have nothing to fear from the longer reach.
