VAT registration in the UAE: thresholds, process and deadlines
VAT registration in the UAE is mandatory above AED 375,000 in taxable supplies, and you have 30 days to apply once you cross it. Here is the threshold test, the EmaraTax process, what happens after your TRN arrives, and what late registration costs.
VAT is the one UAE tax that catches businesses out before they are profitable, because it attaches to turnover rather than to profit. A company that has never made a dirham of profit can still be sitting on a AED 10,000 penalty for registering late. This guide covers the threshold test, the registration process, and what changes on the day your tax registration number arrives.
What VAT in the UAE actually is
Value added tax was introduced on 1 January 2018 and is charged at a standard rate of 5% on most goods and services. It is administered by the Federal Tax Authority through the EmaraTax portal, and it applies across all seven emirates, Dubai included. There is no separate Dubai VAT.
Structurally it works the way VAT works elsewhere. You charge it on what you sell, you pay it on what you buy, and you settle the difference with the FTA. If you have charged more than you have paid, you remit the difference. If you have paid more than you have charged, which is common in a first year of heavy setup costs, you can claim a refund.
Who has to register, and when
There are two thresholds, and the difference between them matters.
Mandatory registration applies once your taxable supplies and imports have exceeded AED 375,000 over the previous twelve months, or when you expect to exceed that figure within the next 30 days. The forward-looking half of that test is the one people forget. A single large contract signed today can trigger a registration obligation before the money has arrived.
Voluntary registration is available from AED 187,500, and can be measured against either your taxable supplies or your taxable expenses. Registering voluntarily is worth considering when your customers are themselves VAT registered businesses, and when you are carrying significant input VAT on setup costs that you would otherwise absorb.
Non-resident businesses have no threshold at all. If you make taxable supplies in the UAE and nobody else is accounting for the VAT on them, you must register from the first dirham.
Once you become liable, you have 30 days to submit the application. Late registration carries a penalty of AED 10,000, and it is charged regardless of whether any VAT was actually due in the period. This is the single most common and most avoidable VAT cost we see.
What counts towards the threshold
The threshold is not your revenue line. It is the total of your taxable supplies, which includes standard-rated supplies at 5%, zero-rated supplies, imported goods and services subject to the reverse charge, and the value of any relevant capital assets you have disposed of.
What does not count: exempt supplies, and anything supplied outside the scope of UAE VAT altogether. Businesses that make only exempt supplies cannot register, because they have nothing to register in respect of.
For the amounts themselves, the UAE VAT calculator adds or removes the 5 per cent for any figure you enter.
Zero-rated is not the same as exempt
This distinction decides whether VAT costs you money or merely passes through you, and it is worth more than any other single point in this guide.
Zero-rated supplies are taxable at 0%. Exports of goods outside the GCC implementing states, international transport, certain newly constructed residential property, and defined healthcare and education services fall here. Because they remain taxable supplies, you can still recover the input VAT on the costs behind them.
Exempt supplies are outside the tax. Bare land, local passenger transport, certain financial services, and residential property after its first supply fall here. You charge nothing, and you cannot recover the input VAT attributable to them. That unrecovered VAT becomes a real cost in your margin.
Businesses that make both kinds of supply have to apportion their input VAT, which is where VAT stops being administrative and starts needing proper bookkeeping.
The registration process step by step
Registration runs entirely through EmaraTax. The mechanics are straightforward, the preparation is where the time goes.
- Create or access your EmaraTax account and open a taxable person profile for the entity that is registering.
- Assemble the documents. Trade licence, passport and Emirates ID for the owners and authorised signatory, memorandum of association or equivalent, proof of authorisation for the signatory, bank account details in the company name, and evidence of turnover such as invoices, contracts or audited figures.
- Complete the turnover declaration. You are stating when you crossed the threshold and on what basis. Get the date right, because it determines your effective registration date and therefore which supplies you should already have been charging VAT on.
- Declare your business activities and customs registration if you import or export goods.
- Submit and respond. The FTA frequently comes back with clarification requests. Answering them promptly is what separates a two-week approval from a two-month one.
When the application is approved you receive a tax registration number (TRN) and an assigned tax period. Both matter immediately.
We can also handle the application for you. What that involves is set out on our VAT registration service page.
What changes once you are registered
The TRN is not the finish line, it is the start of a recurring obligation.
Your invoices change. Every tax invoice must carry your TRN, the correct VAT treatment, and the tax amount stated in AED even where the invoice itself is in another currency. A missing mandatory field can cost your customer their input VAT recovery, which is how VAT problems become commercial problems.
Your filing calendar starts. Most businesses are assigned quarterly periods, larger ones monthly. The return and the payment are both due within 28 days of the end of the tax period. Filing on time but paying late still triggers a penalty.
Your record keeping becomes mandatory. VAT records must be retained for five years, longer for real estate. In practice this means the bookkeeping has to be current rather than reconstructed at the deadline, because a return prepared from an incomplete ledger is a return you will be amending later.
The filing dates that follow from registration are listed in the UAE tax deadline overview.
Deregistration is also an obligation
Deregistration is not optional tidying up. If your taxable supplies fall below AED 187,500 over twelve consecutive months, or you cease making taxable supplies, you must apply within 20 business days of the end of the month in which that occurred. Failing to deregister on time carries its own penalty, and it accrues monthly.
This catches companies that wind down quietly. The trade licence lapses, the business stops, and nobody closes the VAT registration, so the penalties keep running against an entity that has no revenue to pay them.
The mistakes that actually cost money
- Watching revenue instead of taxable supplies. The threshold has its own definition, and it includes items your revenue line does not.
- Ignoring the forward-looking test. Expecting to cross AED 375,000 within 30 days triggers the obligation just as firmly as having already crossed it.
- Treating exempt and zero-rated as interchangeable. One preserves your input VAT recovery, the other destroys it.
- Registering and then not filing. A nil return is still a return. Nothing to declare is not the same as nothing to file.
- Assuming a free zone means no VAT. Only specific Designated Zones receive special treatment, and only for goods under defined conditions. Services are generally treated as supplied onshore regardless.
How we handle VAT for our clients
We run VAT as a continuous process rather than a quarterly scramble: registration and threshold monitoring, bookkeeping to IFRS standards so the return is a by-product of the ledger rather than a project, preparation and filing of returns within the deadline, input VAT recovery reviews, and deregistration when a company winds down.
If you are approaching the threshold and are not sure whether the clock has already started, that is the moment to ask rather than the month after. Book an initial consultation, it is free.

Frequently asked questions
What is the VAT registration threshold in the UAE?
Registration is mandatory once your taxable supplies and imports have exceeded AED 375,000 over the previous twelve months, or when you expect to exceed that figure within the next 30 days. Voluntary registration is possible from AED 187,500, measured on either taxable supplies or taxable expenses.
How long do I have to register for VAT once I cross the threshold?
Thirty days from the point at which you become liable to register. Missing that window carries a late registration penalty of AED 10,000, and the penalty applies whether or not you owed any VAT in the meantime.
Do non-resident businesses have a registration threshold in the UAE?
No. If you make taxable supplies in the UAE and no other person is responsible for accounting for the VAT on them, you must register regardless of value. The AED 375,000 threshold is only available to businesses resident in the UAE.
How often do I have to file a VAT return?
Most businesses file quarterly. Larger businesses are assigned monthly periods. Either way the return and the payment are both due within 28 days of the end of the tax period, and the Federal Tax Authority assigns your period when your registration is approved.
What is the difference between zero-rated and exempt supplies?
Both mean no VAT is charged to your customer, but the consequence for you is very different. Zero-rated supplies, such as exports outside the GCC, still let you recover the input VAT on your costs. Exempt supplies, such as bare land or certain local financial services, do not. That distinction decides whether VAT is a pass-through item or a real cost in your business.
When do I have to deregister for VAT?
If your taxable supplies fall below the voluntary threshold of AED 187,500 over twelve consecutive months, or you stop making taxable supplies altogether, you must apply to deregister within 20 business days of the end of the month in which that happened. Late deregistration carries its own penalty.
