UAE VAT in 2026: Registration Thresholds, Filing, and the Rules That Catch People Out
VAT has been around since 2018, but the mistakes haven’t gone away. Here’s the clean, current picture of when to register, how to file, and what changed for 2026.
VAT is the UAE’s oldest modern tax, and yet it still trips businesses up — usually around the same handful of issues: registering late, forgetting to file a nil return, or misunderstanding the reverse charge. With the penalty framework refreshed for 2026, it’s worth getting the fundamentals straight.
This guide gives you the current rules for registration thresholds, filing, and the changes that matter this year.
The two thresholds that decide everything
UAE VAT is charged at a standard rate of 5%, and whether you have to register depends entirely on your taxable turnover:
- Mandatory registration — once your taxable supplies and imports exceed AED 375,000 over a rolling 12-month period
- Voluntary registration — available once you pass AED 187,500, useful for smaller businesses that want to reclaim input VAT or look established to corporate clients
The mandatory line is AED 375,000 of taxable supplies. Cross it, and you have 30 days to register — miss that, and a fixed penalty follows.
Failing to register within 30 days of crossing the threshold attracts a fixed AED 10,000 penalty, plus retroactive VAT liability on the supplies you made after you should have registered.
How to register
Registration runs through the FTA’s EmaraTax portal:
- Create or log in to your EmaraTax account
- Submit your business details and financial information
- Upload the supporting documents
- Receive your Tax Registration Number (TRN)
A TRN is what lets you legally charge VAT and issue valid tax invoices — and increasingly, it’s what corporate customers expect to see before they’ll work with you.
Filing: the rhythm and the trap
VAT returns are filed for each assigned tax period — typically quarterly, though some businesses are assigned monthly periods — through EmaraTax. Each return reports the VAT you charged on sales (output tax) against the VAT you paid on purchases (input tax); the difference is what you owe or reclaim.
A return is due for every tax period — even one where you made no sales at all. “No activity” is not the same as “no filing.”
This is the single most common slip among voluntarily-registered businesses that go through a quiet patch: they assume silence means nothing to file. It doesn’t.
Two 2026 changes worth knowing
1. The penalty framework was updated. Cabinet Decision No. 129 of 2025 took effect on 14 April 2026, reshaping how VAT penalties are calculated and aligning them more closely with the corporate tax model. For current penalty amounts, always check the FTA portal rather than older guides.
2. Reverse-charge self-invoicing eased. From 1 January 2026, the requirement to issue a self-invoice for standard reverse-charge imports was removed under Federal Decree-Law No. 16 of 2025. The obligation to declare the VAT remains — only the self-invoice paperwork has gone.
Records: the five-year rule
VAT-registered businesses must keep accounting records, issued and received tax invoices, import/export documentation, and credit notes for at least five years. The FTA may request records in Arabic, and being unable to produce them carries its own separate penalty. (Note: corporate tax records are kept for seven years — don’t let the two retention periods confuse you.)
A quick compliance checklist
- Track your rolling 12-month turnover so you spot the AED 375,000 line before you cross it
- Register within 30 days of crossing the threshold — set a reminder, not a hope
- File every period, including nil returns during quiet months
- Account for reverse charge on imported services, even without a self-invoice
- Keep five years of records, organised and retrievable
What this means for you
VAT compliance isn’t complicated, but it’s unforgiving of small lapses. The businesses that stay clean watch their turnover, register on time, and file every period — it comes down to three things to act on:
Watch the AED 375,000 line and the 30-day clock
Mandatory registration triggers once rolling 12-month taxable supplies exceed AED 375,000. Register within 30 days or face a fixed AED 10,000 penalty plus retroactive VAT on supplies made after you should have registered.
File every period — even a quiet one
A return is due for every assigned tax period, including nil returns during slow months. “No activity” is never the same as “no filing”, and that slip catches voluntarily-registered businesses most.
Know the 2026 changes
Cabinet Decision 129 of 2025 reshaped penalties from 14 April 2026, and self-invoicing for standard reverse-charge imports was dropped from 1 January 2026 — though you still declare the VAT and keep five years of records.
Frequently asked questions
Do zero-rated sales count toward the AED 375,000 registration threshold?
Yes — zero-rated supplies are taxable supplies and count toward the threshold; only exempt and out-of-scope income is ignored. If everything you sell is zero-rated (for example, pure exports), you can apply to the FTA for an exception from registration instead.
Can I deregister from VAT if my turnover drops?
Yes. You may apply to deregister if your taxable turnover falls below the voluntary threshold of AED 187,500, and you must apply if you stop making taxable supplies entirely. Keep charging and filing VAT until the FTA approves the deregistration — stopping early is itself a violation.
What if I charge VAT without being registered?
Issuing tax invoices and collecting VAT without a TRN is unlawful: the amounts must be returned and administrative penalties apply. The same goes in reverse — once registered, you must charge VAT from your effective registration date even while the certificate is still being processed.
