Most UAE VAT guidance focuses on registration thresholds. Deregistration gets far less attention — and missing the deadline carries a real, compounding penalty. Here's exactly when it's mandatory, when it's optional, and what happens if you're late.
When deregistration is mandatory
Under Article 21 of Federal Decree-Law No. 8 of 2017, deregistration is mandatory in two situations, and you must apply within 20 business days of the trigger:
- Your business has completely stopped making taxable supplies, or
- Your taxable supplies over the trailing 12 months have fallen below AED 187,500 (the voluntary registration threshold), and you don't expect to exceed it in the next 30 days
When it's optional
If your taxable supplies sit between AED 187,500 and AED 375,000 — below the mandatory registration threshold but still above the voluntary one — deregistration is optional. You can choose to stay registered, or deregister; neither is required.
The 12-month rule for voluntary registrants
If you registered for VAT voluntarily, you generally can't apply to deregister within the first 12 months of that registration, even if your supplies fall below the threshold during that window. This trips up businesses that registered early to reclaim input VAT and then see turnover dip.
The penalty for missing the deadline
Late deregistration carries a penalty of AED 1,000, repeated on the same date each month you remain late, up to a maximum of AED 10,000. It's a compounding cost for something that's entirely avoidable with a calendar reminder.
What has to happen before approval
The FTA won't approve deregistration until you've:
- Filed all outstanding VAT returns
- Settled any outstanding tax liability
- Accounted for VAT on any business assets you're still holding at the point of deregistration (a "deemed supply")
Check your own position
The VAT De-Registration Checker takes your registration type and trailing 12-month taxable supplies and tells you instantly whether deregistration is mandatory, optional, or not yet available to you.
