How to Register for VAT in the UAE

2025-10-02 · 5 min read · By Aureus Worldwide

VAT in the UAE is charged at 5%, and once your business crosses the registration threshold you are legally required to register with the Federal Tax Authority. Registration happens through the EmaraTax portal and is manageable when you understand the thresholds and prepare the right documents. This guide explains who must register, when voluntary registration makes sense, and how to complete the process step by step.

Mandatory and voluntary thresholds

Whether you must register depends on your taxable supplies and imports over a 12-month period:

If you exceed the mandatory threshold, you must register. Below it, voluntary registration can still be worthwhile to recover input VAT and present an established profile to customers. Always confirm current thresholds with the FTA.

Should you register voluntarily?

Voluntary registration can help if you:

• Incur significant input VAT you would like to recover
• Sell mainly to other VAT-registered businesses that can reclaim the VAT
• Want to appear established when bidding for larger contracts

It also brings obligations, charging VAT, filing returns and keeping records, so weigh the administrative cost against the benefit.

Documents you will need

Prepare the following before starting:

• Valid trade licence
• Emirates ID and passport copies of owners and authorised signatories
• Memorandum of Association or equivalent
• Bank account details (IBAN) in the company name
• Financial records evidencing turnover, such as invoices or audited figures
• Customs registration details if you import goods

Step-by-step VAT registration

1. Log in to the FTA's EmaraTax portal or create an account.
2. Add a taxable person and select VAT registration.
3. Enter business details, legal form, activities and turnover.
4. Declare your taxable supplies to confirm which threshold you meet.
5. Upload supporting documents listed above.
6. Add bank details and authorised signatory information.
7. Review and submit the application.
8. Receive your Tax Registration Number (TRN) on approval.

Display your TRN on tax invoices once issued, it is required for valid VAT documentation.

How long registration takes

Once you submit a complete application on EmaraTax with all supporting documents, approval typically follows within a few weeks, though timelines vary with the FTA's workload and the complexity of your business. Incomplete applications take longer, because the authority will come back with requests for further information, restarting the clock. The best way to speed things up is to prepare every document in advance, declare your turnover accurately, and respond quickly to any FTA queries. Do not leave registration until the last moment before a deadline or a large contract, as the lead time is outside your control.

Keeping your registration details current

Registration is not a one-off event. If your business details change, your trade name, activities, address, authorised signatory or bank account, you are generally required to update the FTA within the relevant timeframe. Failing to keep your record current can itself lead to penalties and can cause problems when filing or claiming refunds. Treat your EmaraTax profile as a live record that must reflect your business as it actually is. If your circumstances change so that you no longer meet the registration conditions, there are also rules on deregistration, which must be handled properly rather than simply ignored.

After you register

Registration starts your VAT obligations. You will need to:

• Charge 5% VAT on standard-rated supplies
• Issue valid tax invoices showing your TRN
• File VAT returns for each tax period, usually quarterly
• Pay any net VAT due by the deadline
• Keep records for the period required by law

Getting any of this wrong can lead to penalties, see our guide on UAE VAT penalties and how to avoid them. For choosing help, see the best VAT consultants in Dubai.

How to calculate your taxable turnover

The thresholds are based on taxable turnover, so you need to measure it correctly. Taxable turnover generally includes:

• Standard-rated supplies at 5%
• Zero-rated supplies, such as qualifying exports
• Imported goods and services subject to the reverse charge
• The value of any deemed supplies

It generally excludes exempt supplies and the sale of capital assets. The test looks at a rolling 12-month period, both backward (have you exceeded the threshold over the past 12 months?) and forward (do you expect to in the next 30 days?). Tracking this monthly means you register exactly when required, neither late nor prematurely.

Tax groups and branches

If you operate several related entities, you may be able to register them as a single VAT group under one TRN, so that supplies between members are generally disregarded and you file one return. This can simplify administration and improve cash flow, but it comes with conditions and joint responsibilities. Branches of the same legal entity are typically covered by one registration. Whether grouping is beneficial depends on your structure, so weigh it carefully before applying.

Common registration mistakes

• Registering late after crossing the mandatory threshold
• Understating turnover and selecting the wrong threshold
• Submitting incomplete documents, which delays approval
• Forgetting to update the FTA when business details change
• Failing to display the TRN on tax invoices once issued
