UAE VAT registration and returns

Who must register for UAE VAT

UAE VAT registration and returns are the process of registering a business with the Federal Tax Authority for Value Added Tax and then filing periodic returns that report output and input tax. Registration is mandatory once a business's taxable supplies and imports exceed AED 375,000 in the preceding 12 months, or are expected to exceed that figure in the next 30 days, and it matters because trading past that threshold without registering exposes the business to a fixed penalty on top of the tax itself.

VAT has applied in the UAE at a standard rate of 5% since 1 January 2018, under Federal Decree-Law No. 8 of 2017. A business below the mandatory threshold can still register voluntarily once its taxable supplies, imports or expenses reach AED 187,500, which lets it recover input VAT before it is legally required to charge output VAT on its own sales.

Non-resident businesses have no threshold at all

A non-resident business that makes supplies on which UAE VAT must be charged has to register regardless of the value of those supplies; the AED 375,000 mandatory threshold and the AED 187,500 voluntary threshold apply only to UAE residents. This catches, for example, an overseas supplier making taxable supplies in the UAE with no local place of establishment to fall back on.

Registering through EmaraTax, the Federal Tax Authority's digital tax platform, issues the business a Tax Registration Number, a 15-digit number structured as the first 3 digits identifying the Federal Tax Authority, the middle 9 identifying the business, and the final 3 as check digits, commonly displayed as 100-xxxx-xxxx-xxxx. The same Tax Registration Number is quoted on every VAT return, every tax invoice the business issues, and any correspondence with the Federal Tax Authority, so it is worth setting it up correctly in invoicing and accounting systems from day one rather than retrofitting it once the first return is due.

Tax periods and filing deadlines

The standard UAE VAT tax period is quarterly for businesses with annual turnover below AED 150,000,000. The Federal Tax Authority assigns monthly tax periods instead to businesses with turnover of AED 150,000,000 or more, and it can also assign a monthly period at its own discretion for other businesses. Whichever period applies, the VAT return and any payment due are both due within 28 days after the end of the tax period.

A business should treat the 28-day deadline as fixed to the calendar, not to when the bookkeeping happens to be finished: a quarter ending 30 September, for instance, gives a filing and payment deadline of 28 October, regardless of how long closing the books for that quarter actually took. Where the Federal Tax Authority assigns a monthly period instead of the standard quarterly one, the same 28-day rule still applies, it simply repeats twelve times a year rather than four, which raises the pace at which the books need to close cleanly each period.

Reverse charge on imports

For imports of goods and services from outside the UAE, VAT is generally accounted for under the reverse charge rather than being charged by the overseas supplier. The UAE-registered recipient self-assesses output VAT at 5% on the value of the import in its own return and, where the purchase relates to fully taxable activity, recovers the same amount as input VAT in the same return, so a fully taxable business typically sees a net nil cash effect from the mechanism itself.

The reverse charge still has to be reported correctly even though it nets to nil for a fully taxable business: both the output side and the input side belong in the return, and a business that only records the input recovery while missing the self-assessed output side understates its output tax for the period, which is exactly the kind of error a VAT audit looks for first. A partly exempt business, whose input recovery is restricted, will not see the same net nil effect, so it needs to apply its normal recovery ratio to the reverse-charge input side as well.

Late registration, late filing and late payment penalties

Late VAT registration carries a fixed penalty of AED 10,000, triggered where registration is not completed within 30 days of exceeding the mandatory threshold. Late filing of a return carries AED 1,000 for a first offence and AED 2,000 for a repeat offence within 24 months, and this applies even to a nil return with no tax due.

Late payment penalties changed structure during 2026. Until 13 April 2026, under Cabinet Decision No. 40 of 2017 and No. 108 of 2021, the penalty was 2% of unpaid tax due immediately, a further 4% on the same unpaid amount if still unpaid after 7 days, then 1% per day on the remaining unpaid amount from one calendar month after the due date, capped at 300% of the unpaid tax. From 14 April 2026, Cabinet Decision No. 129 of 2025 replaced that structure with a flat 14% per annum, accrued monthly on the unpaid balance, across VAT, excise tax and corporate tax alike. As of September 2026, the flat 14%-per-annum structure is the one in force.

A worked quarterly VAT return

A UAE trading business has a tax period covering 1 July to 30 September 2026, due 28 October 2026. Its standard-rated sales for the quarter are AED 600,000, giving output VAT of AED 30,000 at 5%. It also has zero-rated export sales of AED 80,000, carrying no VAT. It imports consulting services worth AED 40,000 from an overseas supplier, self-assessing output VAT of AED 2,000 under the reverse charge and recovering the same AED 2,000 as input VAT, since the service relates to fully taxable activity.

On the purchase side, standard-rated domestic purchases total AED 220,000, giving recoverable input VAT of AED 11,000. Total output VAT for the quarter is AED 30,000 plus the AED 2,000 reverse-charge output, AED 32,000; total input VAT is AED 11,000 plus the AED 2,000 reverse-charge input, AED 13,000. Net VAT payable is AED 32,000 less AED 13,000, AED 19,000, due by 28 October 2026.

• Output VAT: AED 30,000 (standard-rated sales) + AED 2,000 (reverse charge) = AED 32,000
• Input VAT: AED 11,000 (standard-rated purchases) + AED 2,000 (reverse charge) = AED 13,000
• Net VAT payable: AED 32,000 - AED 13,000 = AED 19,000
• Filing and payment deadline: 28 October 2026 (28 days after the 30 September quarter end)

What a late payment on that return would cost

If the business above paid its AED 19,000 liability late under the flat penalty structure now in force, the charge accrues at 14% per annum on the unpaid balance, applied monthly. That works out to roughly AED 19,000 multiplied by 14%, divided by 12, close to AED 222 for each month the AED 19,000 stays unpaid, continuing to accrue on whatever balance remains outstanding until it is settled in full.

That is a materially different shape of penalty from the pre-14-April-2026 regime, which front-loaded a 2% hit immediately and a further 4% after just 7 days before daily accrual began; the current flat monthly rate rewards a business that pays even a few weeks late far less harshly for doing so within the first month, but it still keeps accruing for as long as the balance is outstanding, so there is no advantage in delaying payment once a shortfall is identified.

Records you keep after registering

VAT records, including invoices, returns and ledgers, must be retained for 5 years from the end of the relevant tax period, under Federal Decree-Law No. 8 of 2017. Two categories are kept for longer: records relating to capital assets must be retained for 10 years, and real-estate-related records for 15 years, so a business dealing in property or major fixed assets needs a longer retention policy for that slice of its records than for everyday sales and purchase invoices.

This VAT retention period is separate from, and shorter than, the 7-year retention period that applies to Corporate Tax records under the Tax Procedures Law, and separately again from the UAE Commercial Companies Law requirement to keep statutory books of account for a minimum of 5 years from the end of the fiscal year. A business's document retention policy should flag which regime, VAT, Corporate Tax or company law, applies to a given record, since assuming one retention period covers everything risks discarding something the Federal Tax Authority still expects to see.

Mapping the return to the ledger

A VAT return is only as reliable as the ledger behind it: standard-rated, zero-rated and exempt sales need to be distinguishable in the accounts, reverse-charge imports need both an output and an input line, and recoverable input VAT needs to be separated from VAT that is blocked from recovery. A business that can produce these groupings straight from its general ledger, rather than reconstructing them from invoices at filing time, files faster and with fewer corrections.

The same ledger data that supports the return is what an auditor or the Federal Tax Authority will ask to see if a return is queried, so keeping the VAT Input and VAT Output accounts reconciled to the return every period, not just at year end, is worth the discipline even for a small business.
