When do I need to register for VAT in the UAE? The two tests explained

The FTA says a business must register for VAT if the value of its taxable supplies and imports exceeded AED 375,000 over the previous 12 months, or if it expects them to exceed AED 375,000 within the next 30 days. That gives two tests: a look-back over any rolling 12 months and a look-ahead over the next 30 days.

Three words carry the weight. 'Taxable' means supplies taxed at 5% or 0%; exempt supplies do not count towards the threshold. 'Supplies' means sales value, not profit. 'Imports' means goods and services you import that would be taxable if supplied in the UAE.

Take a cleaning company in Abu Dhabi that started in January. Its monthly sales were AED 25,000 for the first six months, then AED 40,000 from July. By the end of September its cumulative taxable supplies are AED 150,000 plus AED 120,000, which is AED 270,000. By the end of November they are AED 350,000. In December they reach AED 390,000, crossing AED 375,000.

The look-back test is met at the end of December. The company should then apply within the time the FTA allows. It is a rolling test: at every month end, add the last twelve months of taxable supplies. A calendar-year view would have missed this until much later.

The second test catches businesses that cross the threshold in one jump. An interior fit-out company with AED 90,000 of sales to date signs a contract for AED 420,000, with the first stage invoice of AED 300,000 due in three weeks. Because it expects taxable supplies of more than AED 375,000 within the next 30 days, the obligation arises now, before that invoice is issued.

This matters because the first big invoice should carry VAT. Registering late means either absorbing the VAT from your own margin or going back to the client to ask for more money, neither of which is pleasant.

Under the administrative penalties as amended by Cabinet Decision No. 129 of 2025, effective 14 April 2026, published summaries list the penalty for failing to register on time at AED 10,000. That is on top of the VAT you should have charged from the date registration was required, which the FTA can assess even though you never collected it from customers.

In the fit-out example above, late registration could mean AED 15,000 of VAT on the AED 300,000 invoice, a AED 10,000 penalty, and late payment penalties on the unpaid tax. Watching the threshold costs far less.

These situations catch owners out more than the basic rule does.

• Counting only invoices paid, when the test uses the value of supplies made.
• Forgetting imported services, such as foreign software or consultants, which can count towards the threshold.
• Assuming a free zone licence removes the obligation; it usually does not.
• Splitting one business across two licences to stay under the threshold, which the FTA can look through.
• Leaving out zero-rated exports, which are taxable supplies and do count.

For businesses not yet registered, HelloBooks tracks rolling 12-month taxable supplies from the sales ledger and shows how close you are to AED 375,000. The AI flags when you are approaching it and when a large quote or contract could trigger the look-ahead test. The decision to apply, and the application on EmaraTax, are yours or your tax agent's.

Once you register, the same ledger switches to charging VAT from the effective date, and the VAT 201 draft builds from the first period.
