If your UAE business is approaching AED 375,000 in taxable turnover, the clock on VAT registration is already running. This guide explains the mandatory and voluntary thresholds, the 30-day application window, what late registration costs, and how to register through the Federal Tax Authority (FTA) portal.
The two VAT thresholds in 2026
UAE VAT has two registration thresholds that apply to taxable supplies, measured over a rolling 12-month period:
- Mandatory registration: AED 375,000. Once your taxable supplies and imports exceed this amount, you must register.
- Voluntary registration: AED 187,500. Below the mandatory threshold you may register voluntarily, which can make sense if your customers are VAT-registered businesses that need to reclaim input tax.
Measuring against a rolling 12-month period means you should check your figures every month, not only at year-end.
The 30-day deadline after you cross the threshold
If your taxable turnover exceeds AED 375,000, you have 30 days to apply for registration. Missing that window creates two problems at once: a late-registration penalty, and VAT that becomes payable on taxable supplies made since you crossed the threshold.
What late registration costs
Under the rules as summarised by GFLO Consultancy, late registration attracts a penalty of AED 10,000. On top of that, you may owe retroactive VAT on the taxable supplies you made after crossing the threshold, and you may need to recover that tax from customers after the fact, which is rarely commercially easy. Treat the 30-day window as a hard deadline.
Step-by-step: how to register for VAT
- Calculate your turnover monthly. Track taxable supplies on a rolling 12-month basis so you see the threshold coming.
- Decide on voluntary registration early. If most of your clients are VAT-registered, registering below the mandatory level can improve their cash flow and your competitiveness.
- Prepare the documents. Have your trade licence, Emirates ID and passport details of the authorised signatory, bank details and a clear description of your business activities ready before you start.
- Apply through the FTA portal. Registration is completed online through the FTA’s EmaraTax platform.
- Set up your VAT processes before the first return. Invoices must show the correct VAT treatment, and your accounting system must capture input and output tax correctly from day one.
Common mistakes that trigger penalties
- Counting only invoices issued, not the full value of taxable supplies over the period.
- Waiting until year-end to review turnover, by which point the 30-day window may already have passed.
- Assuming free zone status exempts a business from VAT. Check your specific supplies and activities, because the answer depends on the facts.
- Issuing invoices without the required tax details before registration is complete.
How VAT fits with your other 2026 obligations
VAT registration sits alongside corporate tax registration, the corporate tax filing deadline, and the e-invoicing rollout. If you are also preparing for corporate tax, read our UAE corporate tax 2026 deadlines guide and the UAE e-invoicing 2026 guide so your systems are built once, correctly.
Frequently asked questions
Do I need VAT registration if my turnover is below AED 375,000?
Not mandatorily. You may register voluntarily once your taxable supplies reach AED 187,500, but registration below the mandatory threshold is optional.
How long do I have to register after I cross AED 375,000?
The published rule is 30 days from the point you exceed the mandatory threshold.
What is the penalty for registering late?
A late-registration penalty of AED 10,000 applies, together with potential retroactive VAT on supplies made since you crossed the threshold.
