VAT has been part of UAE business life since 2018, which is long enough for a comfortable set of half-truths to settle in. The two we hear most: "I'll register when the FTA contacts me" (they won't — the obligation is yours), and "we had no sales this quarter, so there's nothing to file" (there is).
Here's the full picture, with the actual numbers.
When registration stops being optional
VAT registration becomes mandatory when your taxable supplies and imports exceed AED 375,000 over the previous 12 months — or when you expect to cross that line within the next 30 days. It's a rolling 12-month test, not a calendar-year one, which means a strong six months can push you over the threshold mid-year while you're not looking.
Voluntary registration is available from AED 187,500 in taxable supplies or expenses. For businesses selling mainly to VAT-registered customers, voluntary registration is often worth it: you recover VAT on your own costs, and your invoices look like those of an established supplier.
The trap in the rolling test: the clock starts when you cross the threshold, not when you notice. Businesses that only check turnover at year end routinely discover they crossed it months earlier — and the FTA's late registration penalty is a fixed AED 10,000.
Filing: quarterly, 28 days, no exceptions for quiet quarters
Most VAT-registered businesses file quarterly (monthly filing applies above AED 150 million turnover). Your return and payment are due within 28 days of the end of your tax period — and your assigned quarters are set by the FTA at registration, so check your EmaraTax account rather than assuming calendar quarters.
Miss a filing and the penalties are precise: AED 1,000 for the first late return, AED 2,000 for each further late return within 24 months. Late payment adds its own layer: 2% of the unpaid tax immediately, with further monthly percentages accruing on whatever stays outstanding.
Zero sales, nil return, still mandatory
If you're registered, you file every period. A quarter with no sales, no purchases, and no activity still requires a return — a nil return, showing zeros. It takes minutes when your records are in order, and skipping it costs exactly the same AED 1,000/2,000 as missing a real one.
Dormant companies and businesses that have wound down activity are the usual casualties here. If your business has genuinely stopped trading and will stay below thresholds, the right move is VAT deregistration through the FTA, not silence. Silence just accumulates penalties. (The same nil-filing logic applies on the Corporate Tax side too — covered in our Corporate Tax deadlines guide.)
The record-keeping obligation nobody mentions at registration
VAT records must be kept for a minimum of five years — invoices issued and received, import documents, and the workings behind every filed return. When the FTA raises a query about a return, "we don't have that anymore" is not an accepted answer. This is one of the practical reasons proper bookkeeping and VAT compliance belong together rather than being treated as separate chores.
Getting it handled without overpaying
None of this is intellectually difficult. It's a discipline problem: deadlines tracked, records kept, returns prepared from real numbers, filed on time, every single period. That's precisely the kind of work worth delegating cheaply rather than doing badly.
Our VAT registration service is currently AED 199 as a limited period offer, and quarterly return filing starts from AED 299. Both are also included in every monthly accounting package, where the bookkeeping that feeds your returns is handled in the same place.
