VAT Registration & Deregistration in the UAE

Value Added Tax reaches almost every business that sells goods or services in the UAE, yet the question that decides your obligations is a threshold, not a business type. This guide explains when VAT registration in the UAE is mandatory, when it is voluntary, how to register on the EmaraTax portal, and when you can — or must — deregister. It sits inside the wider UAE corporate tax and compliance picture — VAT is only one regime a UAE business meets.

Direct answer. VAT registration becomes mandatory once your taxable supplies and imports pass AED 375,000 over the previous twelve months, and it is available voluntarily from AED 187,500. VAT is governed by Federal Decree-Law No. 8 of 2017 and administered by the Federal Tax Authority through the EmaraTax portal. Below: how each threshold is measured, the registration steps, and the rules for deregistering when a business shrinks or closes.

When VAT registration in the UAE is mandatory

Mandatory registration is triggered by a number, not by how large a company feels. A business established in the UAE must register for VAT once the total value of its taxable supplies and imports exceeded AED 375,000 over the previous twelve months, or where it expects to exceed AED 375,000 within the coming thirty days. "Taxable supplies" means the standard-rated (5%) and zero-rated goods and services you make, plus certain imports — not your profit, and not exempt supplies such as some financial services or the lease of residential property.

Two features of this mandatory VAT threshold catch people out. The test is rolling — you look back across a moving twelve-month window at each month-end, so a strong quarter can push a previously exempt business over the line — and the forward-looking test means a single large contract you know is coming can create the obligation before the money arrives. Once you cross either trigger you must apply within 30 days of being required to register, and registering late carries an administrative penalty of AED 10,000.

Voluntary VAT registration and the AED 187,500 threshold

Below the mandatory line sits a second, optional threshold. A business may choose voluntary VAT registration once its taxable supplies and imports — or, importantly, its taxable expenses — exceed AED 187,500 over the previous twelve months, or are expected to in the next thirty days. The expenses limb matters for early-stage companies: a startup spending on taxable costs but not yet booking much revenue can still register and recover input VAT on those costs.

Voluntary registration is a genuine trade-off, not a free upgrade. It lets you reclaim input VAT and signals to larger counterparties — who expect a Tax Registration Number (TRN) on invoices — that you are established. Against that, you take on the full compliance load from day one: charging 5% (which can make you pricier to unregistered customers), filing periodic returns, and keeping records. You can estimate the 5% due on an invoice with our VAT calculator before deciding whether registering helps or hurts your pricing.

How to register for VAT on EmaraTax

Registration runs entirely through EmaraTax, the Federal Tax Authority's online portal. The broad path is consistent even as individual screens change:

• Create or log in to an EmaraTax account, then add your business as a "taxable person".
• Open the VAT registration application and enter your trade licence details, business activities, and the legal form of the entity.
• Declare your turnover history and expected turnover, and upload supporting evidence — trade licence, the owner's or signatory's Emirates ID and passport, proof of the AED figures (audited financials, bank statements or signed contracts), and bank details for refunds.
• Submit and wait for the FTA to review. On approval you receive a Tax Registration Number (TRN) and an effective date from which you must start charging VAT.

Keep that effective date in view: you must account for VAT from it, even if the TRN certificate arrives later. You can confirm the current steps and document list on the FTA's website at tax.gov.ae.

Tax groups: registering related companies together

Two or more companies under common control in the UAE can register as a single VAT group under one shared TRN. Supplies between members are generally disregarded, and the group files one return instead of several. In exchange, members are jointly and severally liable for the group's VAT — a structuring decision worth taking advice on rather than switching on by default.

After you register: TRN, returns and records

Once registered you carry three standing duties. You charge 5% VAT on your standard-rated supplies and show your TRN on compliant tax invoices. You file VAT returns for each tax period the FTA assigns you — monthly for larger businesses and quarterly for most others, with the FTA setting your filing frequency when it registers you — reporting output VAT collected against input VAT paid, and pay any net amount due by the deadline the FTA sets after the period ends. And you keep VAT records — invoices, credit notes, import and export documents — for at least five years, with a longer period for records connected to real estate. Because VAT and corporate tax draw on the same books, most businesses reconcile one clean set of accounts to both.

VAT deregistration: when you must, and when you may

Deregistration is as rule-bound as signing up, and it is the step businesses forget. You must apply for VAT deregistration if you stop making taxable supplies altogether — for example on ceasing to trade or closing the business — or if your taxable supplies over the previous twelve months fall below the voluntary threshold of AED 187,500. You may apply for voluntary deregistration if your taxable supplies drop below the mandatory threshold of AED 375,000 but stay above AED 187,500, typically once a set period has passed since registration.

The application is filed through EmaraTax within the window the FTA sets after the triggering event, and filing late attracts an administrative penalty — confirm the current deadline and penalty amount with the FTA. Deregistration is not automatic on approval either: you must have filed every outstanding return and settled any tax and penalties before the FTA cancels the registration. Until it does, you remain fully liable to charge, file and pay.

How VAT registration differs from corporate tax registration

It is easy to assume one tax filing covers everything; it does not. VAT under Federal Decree-Law No. 8 of 2017 is a transaction tax on supplies, triggered by the AED 375,000 turnover threshold. Corporate tax under Federal Decree-Law No. 47 of 2022 is a tax on profits, and its registration is mandatory for nearly every business regardless of turnover. You can be registered for one and not the other: a small consultancy under the VAT threshold still registers for corporate tax; a high-turnover, thin-margin business registers for both. Our plain-language guide to how corporate tax works covers that regime in full.

Getting VAT registration right

Almost every VAT penalty comes down to timing — registering late after the rolling twelve-month window crossed AED 375,000, charging before your effective date, or forgetting to deregister after winding down — so check your trailing twelve-month taxable supplies at each month-end. Where the numbers sit close to a threshold, or your structure spans several entities, a short review with a professional is usually cheaper than an audit adjustment.

Frequently asked questions

What is the VAT registration threshold in the UAE?

VAT registration is mandatory once your taxable supplies and imports exceed AED 375,000 over the previous twelve months, or you expect them to exceed AED 375,000 in the next thirty days. Voluntary registration is available from AED 187,500, measured on either taxable supplies or taxable expenses. Both thresholds are governed by Federal Decree-Law No. 8 of 2017 and administered by the Federal Tax Authority through the EmaraTax portal.

Can I register for VAT voluntarily below AED 375,000?

Yes. If your taxable supplies and imports — or your taxable expenses — exceed AED 187,500, you can apply for voluntary VAT registration even though you are under the mandatory line. The expenses basis is useful for startups spending on taxable costs before earning much revenue, because it lets them recover input VAT. The trade-off is that you must then charge 5%, file returns and keep records like any registered business.

How do I register for VAT on EmaraTax?

You register through EmaraTax, the Federal Tax Authority's online portal. Log in, add your business as a taxable person, open the VAT registration application, and enter your trade licence, activities and turnover. You upload supporting documents — trade licence, owner's Emirates ID and passport, evidence of your turnover figures and bank details — then submit for review. On approval you receive a Tax Registration Number and an effective date from which you must charge VAT.

When can I deregister from VAT in the UAE?

You must apply to deregister if you stop making taxable supplies, or if your taxable supplies over the previous twelve months fall below AED 187,500. You may apply for voluntary deregistration if they drop below AED 375,000 but stay above AED 187,500. Deregistration is filed through EmaraTax and is not final until every outstanding return is filed and any tax and penalties are paid, so you stay liable until the FTA confirms it.

Is VAT registration the same as corporate tax registration?

No. They are separate regimes with separate thresholds and returns. VAT under Federal Decree-Law No. 8 of 2017 is a 5% tax on supplies, triggered when taxable supplies pass AED 375,000. Corporate tax under Federal Decree-Law No. 47 of 2022 is a tax on profits, and its registration is mandatory for nearly every business regardless of turnover. A business can be registered for one, both, or in rare cases neither, depending on its activity.

What happens if I register for VAT late?

Registering after you have crossed the AED 375,000 threshold exposes the business to an administrative penalty set by the Federal Tax Authority, and you remain liable for the VAT you should have charged from your effective date. Because the threshold is measured on a rolling twelve-month basis, businesses often cross it without noticing. If you think you have registered late, apply as soon as possible and take advice on your penalty exposure and any voluntary disclosure.
