Test 1 — The last 12 months
Add up your taxable supplies and imports over the previous 12 months. If the total exceeds AED 375,000, registration is mandatory. This is a rolling 12 months — not the calendar year, not your financial year.
VAT registration, demystified
VAT in the UAE is 5% — but the first question every business asks is simpler: do I even have to register? The answer sits in one number, AED 375,000, and two tests. This guide shows you exactly where you stand, how the 20-business-day clock works, and what it costs to get it wrong.
The trigger
You don't wait for a letter from the FTA. You run these two tests yourself, continuously — and the moment either one fires, the clock starts.
Add up your taxable supplies and imports over the previous 12 months. If the total exceeds AED 375,000, registration is mandatory. This is a rolling 12 months — not the calendar year, not your financial year.
If you expect to exceed AED 375,000 in the next 30 days alone — a signed contract, a confirmed order book — you must register now. You don't wait for the money to land.
We prepare workings, schedules and compliance-ready records. For regulated representation before the FTA we work with registered UAE tax partners.
What's counted
Not all revenue is equal in the FTA's eyes. Before you run the test, sort your income into the right buckets:
If your revenue mix includes zero-rated or exempt income, get the split right before you decide anything — our VAT services team does this assessment as a matter of routine.
Voluntary registration
Below AED 375,000 you can still register voluntarily once you pass AED 187,500 in taxable supplies, imports or taxable expenses. Sometimes that's the smart move.
Fit-out, equipment, initial stock — if your setup phase carries heavy 5% VAT, registering early lets you recover input VAT instead of absorbing it as a cost.
Selling B2B? Your clients reclaim the VAT you charge, so your 5% costs them nothing — and a TRN on your invoice signals you're a serious supplier.
Registration means quarterly returns, 5-year record keeping and invoice discipline. If your input VAT is tiny, the admin may outweigh the benefit — run the numbers first.
The clock
Cross the threshold and you have 20 business days — Sunday to Thursday in the UAE — to submit your application on EmaraTax. Here's how the maths works in practice.
(A hypothetical example to show the calculation.) Monthly taxable supplies: AED 30,000 for months 1–9 (AED 270,000), then AED 40,000 in month 10 (AED 310,000), AED 45,000 in month 11 (AED 355,000), and AED 50,000 in month 12 — taking the rolling 12-month total to AED 405,000.
The threshold was crossed during month 12, on the day the rolling total passed AED 375,000. The 20-business-day application window starts that day — not at month-end, not when the accountant notices.
Now the forward test: in month 6, the agency signs a AED 420,000 annual retainer starting the following month. Test 2 fires immediately — the application is due within 20 business days of signing, even though the previous 12 months only totalled AED 310,000.
The pattern we see most: businesses track revenue monthly but never run the rolling 12-month total — then discover they've been over the line for two quarters. Monthly reconciled books make this a five-minute check.
Avoid these
The test is a rolling 12 months. A business that crosses the line in March and waits for year-end is already late — and the penalty clock doesn't care about your financial year.
Goods you import count toward the threshold. E-commerce sellers and traders routinely cross AED 375,000 on imports alone, months before their sales suggest it.
The penalty is AED 10,000 — but the real sting is retroactive VAT. The FTA assesses VAT on your supplies from the date registration was due, and you never collected it from customers.
Free zone companies register under exactly the same rules. Location changes nothing about the threshold test.
Registering at AED 187,500 to look established, then discovering quarterly filings and invoice discipline eat more time than the recovered VAT is worth.
One big signed contract can trigger registration overnight. Sales teams celebrate the deal; nobody tells finance — until the FTA does.
Next steps
VAT registration is one piece of a bigger compliance picture. Once registered, you'll file quarterly returns — our VAT return filing guide walks through that process — and your corporate tax position runs on a separate track with its own deadlines.

VAT registration FAQs
No — registration becomes mandatory when your taxable supplies and imports exceed AED 375,000. At exactly 375,000 you're not over the line yet, but watch the number closely: the next dirham starts the 20-business-day application clock.
Yes. Zero-rated supplies — including exports — count toward the AED 375,000 threshold even though you charge 0% VAT on them. Exempt supplies, such as financial services or residential property rental, do not count.
Yes. Free zone companies follow the same VAT registration rules as mainland companies. Being in a free zone doesn't change the threshold test or the 20-business-day deadline.
Processing times vary with the FTA's review queue and whether your documents are complete. Apply as soon as the threshold is crossed rather than waiting — and check current timeframes on the EmaraTax portal.
You can apply for VAT deregistration once your taxable supplies stay below the voluntary threshold of AED 187,500 for 12 consecutive months, or if you stop making taxable supplies. Our VAT deregistration guide covers the full process.
No. You may only charge VAT once registered and holding a TRN. And if you registered late, the FTA can still assess VAT on your supplies from the date registration was due — VAT you never collected from customers. We can check your position free.
