Every Deadline, Worked Out From Your Dates

Free·Nothing is sent or stored·Updated

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.

Do we have to register for VAT?

When is our VAT return due?

Twenty-eight days from the end of the tax period, for the return and the payment alike.

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.

Do you hold a current, verified TRN for every VAT-registered business customer?
What VAT rate do your systems store on standard-rated lines?
Does every product and service line carry a mapped tax category (standard, zero-rated, exempt, out of scope)?
Do you invoice in currencies other than AED?
Do you know your TIN, the first ten digits of your Corporate Tax TRN?
Does every invoice line carry a quantity and a unit of measure?
Do any supplies involve free zones, the margin scheme, e-commerce, exports, or deemed supplies?
Do you capture your customers’ electronic addresses for invoice delivery?

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.

Is the entity a juridical person (a company or a branch, not a partnership or trust) established in a free zone?
For each activity, can you name the people, assets and expenditure in the zone that perform its core income-generating work?
Has every revenue stream been mapped against the Qualifying Activities and Excluded Activities lists, in writing?
Are related-party transactions priced at arm's length, with documentation to support it?
Do you prepare audited financial statements?

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.
