When must you register for VAT in the UAE (and what late registration costs you)

A clear guide to UAE VAT registration thresholds in 2026: AED 375,000 mandatory, AED 187,500 voluntary, how the rolling 12 month calculation works, and the AED 10,000 penalty for registering late.

"Do I need to register for VAT?" is one of the most common questions we hear from business owners in the UAE. The answer is not complicated, but the arithmetic behind it catches people out. This article lays it out plainly.

The two numbers that matter

These thresholds are set by the Federal Tax Authority and remain unchanged for 2026:

AED 375,000, the mandatory registration threshold. If your taxable turnover exceeds this figure across any rolling 12 month period, registration is compulsory.
AED 187,500, the voluntary registration threshold. Once you pass this figure but have not yet reached AED 375,000, you may register voluntarily. This can be worthwhile when your costs carry recoverable input VAT.

What "rolling 12 months" actually means

It is not the calendar year from January to December. It means any consecutive 12 month window ending on today's date. For example, if today is June 2026, the period that counts is July 2025 to June 2026.

The practical consequence: you have to watch your turnover month by month. You cannot wait until the year end to discover you crossed the threshold several months ago without registering.

What counts toward taxable turnover

The total is built from:

Standard-rated and zero-rated supplies of goods and services.
The market value of supplies to related parties made at a non-market price.
Imported goods and services that fall under the reverse charge mechanism.

What does not count: VAT-exempt supplies (such as certain residential property rents and some financial services), and the sale of capital assets held for personal use.

What happens if you register late

The penalty for late registration is a fixed AED 10,000, applied immediately and regardless of any tax that may also be due.

If you have been charging for services without being registered, the FTA can require you to account for the VAT that should have been collected on past transactions from the date registration became mandatory, with additional late payment penalties accruing at 14% per annum.

The short version: being late costs more than registering early.

How to track this in practice

The simplest method: at the end of each month, total your taxable turnover for the trailing 12 months. If you are approaching AED 300,000, start preparing to register before you reach AED 375,000, rather than after.

At Lume we monitor this figure automatically for every client and alert them when they reach 80% of the threshold. A tax surprise is always harder to deal with than early preparation.

Frequently asked questions

Is voluntary registration worth it?

It is worthwhile when your operating purchases and expenses carry recoverable input VAT, particularly in the early stages of a business when setup costs are high. If your sales go mainly to individuals who cannot reclaim VAT, registering early may discourage purchases by adding 5% to your prices.

Does revenue from outside the UAE count toward the threshold?

Exports and the supply of services to non-residents outside the UAE are generally treated as zero-rated taxable supplies, so they are included in the registration threshold calculation. Specific cases should be reviewed with a tax adviser.

How is the threshold calculated for a newly formed company?

If you reasonably expect to exceed AED 375,000 within the next 30 days, you must register immediately. You can also register on the basis of expected turnover for the coming 12 months, even if you have not yet generated revenue.

What if revenue spikes seasonally above the threshold then falls back?

Registration remains mandatory even if the spike is seasonal. Once you exceed AED 375,000 across any rolling 12 month period, you must register. You can apply to deregister later if turnover stays consistently below the threshold for a reasonable period.
