Search for UAE e-invoicing deadlines and you will find the same date over and over: 30 October 2026. Appoint your Accredited Service Provider by then, the articles say, or face penalties.
If your revenue is below AED 50 million, that date is not yours. Yours is 31 March 2027.
What changed
Nothing changed this month. That is rather the point. The timetable has been settled in law since Ministerial Decision No. 244 of 2025, and the only amendment since, Ministerial Decision No. 66 of 2026 in May, moved one date for one category. It pushed the appointment deadline for businesses at or above AED 50 million from 31 July to 30 October 2026. It moved nothing else, and it changed no go-live date.
The full picture looks like this. Businesses at or above AED 50 million in revenue appoint a provider by 30 October 2026 and go live on 1 January 2027. Businesses below AED 50 million appoint by 31 March 2027 and go live on 1 July 2027. Government entities appoint by 31 March 2027 and go live on 1 October 2027.
The coverage skews toward the first row because that is where the consultancies sell. The result is a lot of smaller businesses who either think they have a deadline in six weeks, or having checked and found they do not, assume they have nothing to worry about until mid-2027.
Both readings cost you.
The trap in the middle
Appointing a provider is not a software purchase you can schedule when convenient. It is a regulatory act with its own deadline and its own fine. Under Cabinet Decision No. 106 of 2025, failing to appoint on time carries AED 5,000 per month. That clock starts on 1 April 2027, three months before a single invoice is due to flow through the system.
So the gap between 31 March and 1 July is not slack. It is your implementation window, and it is about three months to onboard with your provider, map your invoice types to the PINT AE format, clean up tax registration numbers and customer records, and run real tests. If you operate more than one entity, that is tight.
What to do this week
- Work out which revenue band you are in, using the test in the decision rather than a rough estimate. If you are near AED 50 million, get this checked.
- Start your shortlist from the Ministry of Finance list of providers, not from a vendor blog or a comparison page.
- Check which of the Ministry's two lists each name sits on. Accredited providers have completed the full process, including a live trial on the production environment with the Federal Tax Authority. Pre-approved providers are still in testing and have no accreditation number. Nothing in law says you cannot appoint a pre-approved provider, but ask in writing when they expect full accreditation, and compare that to your go-live date rather than your appointment deadline.
- Start cleaning master data now. Missing or wrong tax registration numbers and inconsistent customer records cause most invoice rejections, and that work is yours, not your provider's.
