Every Deadline, Worked Out From Your Dates
Most UAE tax penalties are not penalties for wrong answers. They are penalties for late ones, and the dates are arithmetic rather than judgement. These calculators do that arithmetic from your own numbers, and each one tells you what the answer actually means. Everything runs in your browser: nothing you type is transmitted, logged, or stored.

Do we have to register for VAT?
Residents register at AED 375,000 of taxable supplies, with voluntary registration from AED 187,500. Non-residents have no threshold at all. Both resident thresholds are measured on a rolling 12 months, not a financial year.
When is our VAT deregistration due?
Deregistration is not optional when the conditions are met, and applying late is penalised in its own right.
When is our VAT return due?
Twenty-eight days from the end of the tax period, for the return and the payment alike.
When must we register for Corporate Tax?
Registration follows legal personality and presence, not profitability. Dormant companies and entities expecting a 0% outcome register too.
When is our Corporate Tax deregistration due?
Three months from cessation, dissolution or liquidation, with a final return behind it.
When is our Corporate Tax return due?
Nine months from the year end, which is less generous than it sounds once the audit and the elections are accounted for.
Can we elect Small Business Relief?
An annual election, now extended to eligible tax periods ending on or before 31 December 2029. Read the updated conditions.
Which e-invoicing phase are you in?
Your deadlines depend on revenue and entity type. This gives you both dates, the time left, and the date the preparation work actually needs to start.
Will your invoices pass validation?
Every UAE e-invoice is tested against the PINT AE rules, and a fatal failure means the invoice does not exist as a tax document. Eight questions about your billing data predict where yours would fail, before your accredited provider tells you.
Does your free zone company still hold the 0% rate?
Qualifying Free Zone Person status is a set of conditions maintained continuously, not a status granted once. Any single failure costs the rate. This tests each condition and calculates your de minimis headroom.

Your answers and the indicative result are attached automatically, so you do not have to explain the situation from scratch. A principal replies, usually within one business day.
Where these rules come from
The Corporate Tax deadlines, registration edge cases and the reasoning behind them are covered in our commentary on who is actually inside the regime and our full tax calendar. Small Business Relief, including when electing it is a mistake, is set out in our relief guide.
The e-invoicing phases, the extension of the Phase 1 appointment date from 31 July to 30 October 2026, and the published penalties are in our guide to the mandate. The free zone conditions and the five-year consequence of breaching de minimis are covered in the Qualifying Income guide, and how the FTA tests substance in practice in our commentary on its private clarifications.

A result you did not expect?
That is usually worth an hour of a principal's time rather than a week of worrying. Send us the structure and we will tell you where it actually stands.
