UAE VAT Deadlines and Penalties: Registration, Filing, Payment

A company in the UAE doesn't register on time after crossing the VAT threshold - that's the first penalty, but not the only one: it files a return late - a second penalty, pays the tax late - a third, growing every month. These are three separate violations, and they add up rather than cancel each other out.

A separate and more expensive mistake is to assume that an invoice to a foreign client is automatically exempt from VAT. It isn't, and here's why.

Step 1. Registration - threshold and fixed penalty

VAT registration is mandatory once a company's taxable supplies and imports exceed AED 375,000 over the last 12 months, or exceeding that amount in the next 30 days is expected. This threshold applies to businesses with a place of residence or establishment in the UAE (Article 13(1), Decree-Law 8/2017). If the business has no place of establishment in the UAE, there is no threshold at all: registration is mandatory from the first taxable supply in the UAE, unless the recipient is liable for the tax under the reverse charge mechanism (Article 13(2)). From the moment the threshold is exceeded, the business has 30 days to apply with the FTA through EmaraTax.

Filing the application late carries a fixed penalty of AED 10,000 (Cabinet Decision 40/2017, as amended, including by Cabinet Decision 129/2025), regardless of how late the filing is or the company's turnover. But the fine itself isn't the only risk: a business that registers late is liable to charge and pay VAT on all taxable supplies made during the entire period before actual registration (Article 7(7) of the Executive Regulation, Cabinet Decision 52/2017) - for turnover above average, that sum can end up bigger than the fine itself.

Voluntary registration is a separate, earlier threshold (AED 187,500 of taxable supplies, imports, or taxable expenses incurred in the UAE - Article 8(5) of the Executive Regulation, Cabinet Decision 52/2017), available to a business that conducts business in the UAE and intends to make taxable supplies (Article 8(6) of the same regulation). It's a right to register earlier, not an alternative to mandatory registration: it does not remove the obligation to apply once turnover reaches AED 375,000, and the late-registration penalty at that point applies on the usual grounds.

Step 2. Filing - the penalty grows on repeat

After registration, the company files a return for the tax period assigned by the FTA - monthly or quarterly, depending on turnover. Filing the return and paying the tax for that period are both due 28 days after it ends (Article 64 of the Executive Regulation, Cabinet Decision 52/2017): for example, if a period ends on 31 March, the deadline is 28 April.

The penalty for filing a return late is:

• AED 1,000 - for the first violation;
• AED 2,000 - for a repeat violation within 24 months.

The 24-month window matters on its own: a company that was late once by accident pays less than one with recurring delays - these are different-priced situations, and the second one is worth treating separately rather than as routine.

Step 3. Payment - a separate counter charged as a percentage

If the return is filed but the tax isn't paid within the same 28 days, a separate mechanism kicks in, distinct from the filing penalty: from 14 April 2026, the unpaid amount accrues 14% per annum, charged monthly (Cabinet Decision 129/2025) - this rate replaced the previous system of 2% immediately plus 4% per month plus daily accrual. Before 14 April 2026, the previous regime applied: when calculating older periods, check which regime was in force on the date of the delay rather than applying the current rate retroactively.

Exporting services to a foreign client - not automatically 0%

A separate and frequent trap - not about deadlines, but about the rate itself. Billing a company outside the UAE doesn't automatically mean the zero rate applies: zero-rating an exported service goes through a place-of-supply test (Article 31 of the Executive Regulation, clarified in Public Clarification VATP019/2020). The zero rate is possible if the recipient of the service has no place of residence in the UAE and is physically outside the UAE at the time the service is performed. A brief presence of the recipient in the UAE - under a month and unrelated to the service - does not by itself disqualify the supply from the zero rate. The address on the invoice is only one indicator of such presence, not sufficient grounds on its own to apply 0%.

Common mistakes

Assuming that without exceeding the threshold last year, registration isn't needed. The threshold is based not only on the actual figure for the past 12 months but also on the expectation of exceeding it in the next 30 days - missing that can mean missing the deadline. Solution: check both conditions, not just past actual turnover.

Confusing the return deadline with the company's registration date. The FTA assigns the filing period after registration, and the countdown runs from that assigned period (28 days after it ends), not from the date the company appeared in the UAE. Solution: track the actual tax period assigned by the FTA.

Delaying tax payment after the return has already been filed. The 14% per annum keeps accruing monthly even if the return itself was filed on time - both actions share the same 28-day deadline. Solution: pay the tax on the same deadline as filing the return.

Automatically zero-rating VAT on invoices to foreign clients. Without checking the place of supply, zero-rating can be wrong, and the extra 5% has to be paid out of pocket. Solution: run every such deal through the export-of-services test rather than judging by one address on an invoice.
