Updated October 2026. Reflects Federal Decree-Law No. 8 of 2017 on VAT, its Executive Regulation, and the penalty changes in Cabinet Decision No. 129 of 2025, effective 14 April 2026.
Most UAE businesses know there is a VAT threshold. Fewer know how it is actually measured, when the 30-day clock starts, or that the real cost of registering late is usually not the penalty.
This guide covers who must register, how to test the threshold correctly, what the FTA asks for, how the EmaraTax application works, and what changes the day your Tax Registration Number (TRN) is issued.
The short answer
You must register for UAE VAT once your taxable supplies and imports exceed AED 375,000 over the past 12 months, or are expected to exceed it in the next 30 days. You can choose to register from AED 187,500. The application is made on EmaraTax within 30 days, and registering late costs AED 10,000 plus the VAT you should have charged.
The two VAT registration thresholds
| Threshold | Amount | What it means |
|---|---|---|
| Mandatory | AED 375,000 | You must register and start charging 5% VAT |
| Voluntary | AED 187,500 | You may register if you choose to |
Both are tested on a rolling 12-month basis, not a calendar or financial year. The question is never “what did we earn in 2025?” It is “what did we earn in the last twelve months, at the end of this month?”
Two tests, and either one triggers registration
The look-back test. At the end of any month, add up your taxable supplies and imports for the previous 12 months. If the total exceeds AED 375,000, you are required to register.
The look-forward test. If you expect your taxable supplies and imports to exceed AED 375,000 in the next 30 days alone, you are required to register now, before the supplies are made.
The look-forward test catches growing businesses. A startup that signs a single AED 400,000 contract due to be invoiced next month is required to register before it invoices, even if its history is well under the threshold.
What counts toward the threshold, and what doesn't
| Counts toward AED 375,000 | Does not count |
|---|---|
| Standard-rated sales at 5% | Exempt supplies (for example, residential rent, certain financial services) |
| Zero-rated sales, including exports | Out-of-scope income |
| Imports of goods and services under the reverse charge | Sales of capital assets |
| Supplies made by related businesses, if they are effectively one business | Salaries and personal income |
The two mistakes we see most often are counting only invoiced revenue, so that reverse-charge imports of services such as software subscriptions, marketing and foreign consultants are missed, and leaving out zero-rated exports because “no VAT is charged on them”. Both still count.
Who must register regardless of the threshold
Non-resident businesses. A business with no place of establishment in the UAE has no threshold. It must register from its first taxable supply in the UAE if no other person in the UAE is required to account for the VAT on it.
Free zone companies. A free zone licence does not exempt you from VAT registration. Whether a specific supply is inside or outside the UAE for VAT depends on whether your zone is a VAT Designated Zone, and on the exact area you operate from. Our guide to free zone vs designated zone explains how the three tax laws each define it differently.
If you only make zero-rated supplies, you may apply to the FTA for an exception from registration rather than registering. It is not automatic, and you still have to notify the FTA if your supplies change.
Should a startup register voluntarily?
Voluntary registration is not only for businesses close to AED 375,000. You can also qualify on taxable expenses: if what you have spent, or expect to spend, on standard-rated costs exceeds AED 187,500, you can register before you have made a single sale.
That matters at setup stage. Fit-out, equipment, licensing, software and professional fees all carry 5% VAT. Registered businesses can generally recover that input tax. Unregistered businesses cannot.
| Register voluntarily if | Wait if |
|---|---|
| Your setup costs are high and mostly standard-rated | Your costs are low or mainly exempt |
| Your customers are VAT-registered businesses that can recover the VAT you charge | Your customers are consumers who would bear the extra 5% |
| You expect to cross AED 375,000 within a year anyway | You have no clear path to the threshold |
Once you register voluntarily, you generally cannot deregister in your first 12 months. Treat it as a commitment, not an experiment.
Documents needed for UAE VAT registration
The FTA usually asks for the following. Missing or inconsistent documents are the most common reason applications are sent back.
- Valid trade licence, or licences if you have more than one
- Memorandum and Articles of Association, or partnership agreement
- Passport and Emirates ID of the owners, managers and authorised signatory
- Proof of authority for the signatory, such as a power of attorney or board resolution
- Bank account details, normally an IBAN confirmation letter from the bank
- Evidence of turnover: 12 months of sales figures, audited or management accounts, sample invoices
- Expected turnover and expenses for the next 30 days, if registering on the look-forward test
- Customs registration number, if you import or export goods
- Business address, contact details and a description of your activities
Your declared turnover must match your evidence. If your application states AED 600,000 and your sales ledger shows AED 450,000, expect the FTA to ask why.
How to register for VAT on EmaraTax: step by step
- Create an EmaraTax account at the FTA portal using a business email and mobile number.
- Create a Taxable Person profile for your company. One profile holds all your tax registrations, including Corporate Tax.
- Open the VAT registration application and select mandatory or voluntary registration.
- Enter entity, ownership, activity and banking details, consistent with your trade licence.
- Declare your turnover under the look-back or look-forward test, and the date the threshold was crossed.
- Upload the documents listed above.
- Review and submit. The FTA may send the application back for more information, so respond promptly, because time spent on corrections still counts against you.
- Receive your TRN. The FTA confirms your registration and the effective date from which you must charge VAT.
Processing typically takes around 20 business days for a complete application, and longer if the FTA requests clarification.
VAT registration and Corporate Tax registration are separate
Registering for Corporate Tax does not register you for VAT, and the reverse is also true. Most UAE companies need both, on the same EmaraTax profile, with different thresholds and deadlines. Small Business Relief is a Corporate Tax relief only: it does not change your VAT position. See our guide to Small Business Relief.
What happens if you register late
The penalty for failing to register on time is a fixed AED 10,000. It was not changed by the 2026 penalty reform.
That is rarely the expensive part. When the FTA backdates your registration to the date you should have registered, you become liable for 5% VAT on every taxable sale made since then, whether or not you charged it to your customers.
A business that crossed AED 375,000 a year ago and has since invoiced AED 1,200,000 without VAT now owes about AED 60,000 in VAT it never collected, plus the AED 10,000 penalty, plus 14% a year late payment on the unpaid VAT under Cabinet Decision No. 129 of 2025. Recovering that VAT from customers after the fact is often not possible.
After you receive your TRN
From your effective date of registration, you must:
- Charge 5% VAT on standard-rated supplies and show it correctly on every invoice
- Issue compliant tax invoices showing your TRN, and from 2027 issue them as electronic invoices. See our guide to UAE e-invoicing
- File VAT returns and pay within 28 days of the end of each tax period, usually quarterly. Late filing costs AED 1,000, rising to AED 2,000 for a repeat within 24 months
- Keep records for at least five years
- Verify your suppliers before recovering input tax. From 1 October 2026, a valid tax invoice alone is no longer enough. See VAT input tax rules
- Update the FTA within 20 business days if your licence, address, activities or ownership change
When you must deregister
You must apply to deregister if you stop making taxable supplies, or if your taxable supplies over the past 12 months fall below AED 187,500 and are not expected to rise above it. The application is due within 20 business days. Failing to apply on time is penalised, so deregistration needs the same attention as registration.
Common VAT registration mistakes
1. Testing the threshold on a calendar year. The test is rolling and is checked at the end of every month.
2. Ignoring the look-forward test. One large contract can trigger registration before any revenue is earned.
3. Leaving out zero-rated exports and reverse-charge imports. Both count toward AED 375,000.
4. Assuming a free zone licence means no VAT. It does not.
5. Assuming Corporate Tax registration covers VAT. They are separate registrations.
6. Registering late and treating AED 10,000 as the cost. The backdated VAT is usually much larger.
