TRN Verification
Verifying a UAE tax registration number before you pay VAT on an invoice.
Closing or Falling Below
VAT deregistration is mandatory in some situations and optional in others, and the mandatory one has a deadline most companies do not know is running.
Deregistration is required where the business stops making taxable supplies, or where turnover falls below the mandatory threshold and is not expected to recover. An application is made to the Federal Tax Authority within a set period, and outstanding returns and liabilities must be dealt with before it is approved.
| Authority | Federal Tax Authority |
|---|---|
| Mandatory when | Taxable supplies cease, or turnover falls below the threshold |
| Deadline | Applies to mandatory cases |
| Required first | Returns filed, liabilities settled |
| Late application | Penalty applies |
| Thresholds | Covered in our VAT threshold guide |

Two situations. The business stops making taxable supplies altogether, typically on closure or a change of activity. Or turnover falls below the mandatory threshold and is not expected to recover within the period the rules specify.
The second is the one companies miss, because a quiet year does not feel like a compliance event until the deadline has passed.
Where turnover has fallen below the mandatory level but remains above the voluntary one, and the compliance burden outweighs the benefit of recovering input VAT.
It is a genuine calculation rather than an obvious answer. A business with significant input VAT may prefer to stay registered even when it no longer has to be.
Returns for every period up to deregistration, and any liability arising. A final return is normally required, and there may be an adjustment on assets held at deregistration.
That adjustment surprises businesses holding stock or capital assets, and it is worth understanding before applying rather than after.
You register again once the threshold is met, and the obligation to monitor turnover returns with it. Businesses that deregister in a quiet year and then recover strongly sometimes miss the re-registration point.
If the downturn looks temporary, staying registered may be simpler than exiting and re-entering.
| Your situation | Position |
|---|---|
| Stopped making taxable supplies | Mandatory |
| Turnover below the mandatory threshold, not recovering | Mandatory |
| Below mandatory, above voluntary threshold | Optional |
| Temporary dip, recovery expected | Usually stay registered |
| Company being liquidated | Mandatory, alongside corporate tax |
The figures that decide everything are the turnover numbers for the relevant periods. Send those first; whether deregistration is mandatory or optional turns entirely on them.
