VAT registration for a UAE online seller

The two thresholds

Registration is mandatory once your taxable supplies and imports exceed AED 375,000 over any rolling twelve-month period. It is voluntary from AED 187,500.

The word doing the work there is rolling. It is any twelve consecutive months, not your financial year — so a shop that has a strong Ramadan and a strong White Friday can cross the line in March even though its year ends in December.

Why anyone registers voluntarily

Registering lets you recover the VAT you pay your own suppliers. If you buy a lot from VAT-registered businesses in the UAE, that input tax is real money you are currently absorbing.

It also matters commercially: a business customer who cannot get a valid tax invoice from you cannot recover the tax they pay you, which effectively makes you 5% more expensive than a registered competitor. Why that matters for B2B →

What a TRN actually is

A Tax Registration Number is a fifteen-digit identifier issued by the Federal Tax Authority. It has to appear on every tax invoice you issue, and business customers will check it.

Applications go through EmaraTax, the FTA's portal. You will need your trade licence, the shareholder documents, your bank details and a reasonable estimate of turnover.

What changes on your store the day it arrives

Practically: you enter the TRN once in settings, and from that moment the store issues tax invoices instead of ordinary receipts.

What should not change is your shelf prices. UAE consumers see VAT-inclusive prices, so registering does not mean adding 5% to every label — it means the tax that was already inside the price starts being declared and shown separately on the invoice.

The arithmetic runs backwards from the shelf price: the VAT inside a VAT-inclusive amount is price × 5 ÷ 105, not price × 5%. The full explanation, with the invoice fields →

Filing, and what the store owes you

You file through EmaraTax, either yourself or through a tax agent. What the software owes you is a number you can defend: output tax by period, with credit notes deducted and zero-rated and exempt supplies separated.

The two places this goes wrong for e-commerce are refunds and Cash on Delivery. A refund has to reverse the tax proportionally, and a COD order that was never collected has to be cancelled properly — otherwise its tax sits in your return as output tax on money you never received.
