UAE e-invoicing deadlines, explained by business size

The single question most business owners have about UAE e-invoicing is simple: “By when do I have to do this?” The answer depends on your size. The rollout is phased, so larger businesses go first and smaller ones follow. Here’s the shape of the timeline.

Timelines can still move. The large-business deadline to appoint a provider has already been pushed back once (from 31 July to 30 October 2026), so always check the latest against the official source linked at the top of this page before you act.

The timeline at a glance

Phase	Who	Appoint an ASP by	Mandatory go-live
Voluntary pilot	Any business that opts in	Optional, from 1 July 2026	None (voluntary)
Wave 1	Revenue over AED 50M	30 October 2026	1 January 2027
Wave 2	Revenue under AED 50M	31 March 2027	1 July 2027
Government entities	UAE government bodies	31 March 2027	1 October 2027

The voluntary pilot opened on 1 July 2026, so any business that wants to get on the system early can. The wave dates below it are the ones that become compulsory.

What the dates mean in practice

There are really two dates that matter for you, not one:

1. The “appoint an ASP” date. By this point you need to have chosen and connected an Accredited Service Provider (the partner that transmits your invoices through the approved network). This comes first: 30 October 2026 for Wave 1, and 31 March 2027 for Wave 2.
2. The “go-live” date. By this point your invoices must actually be issued in the required format and flowing through that channel: 1 January 2027 for Wave 1, and 1 July 2027 for Wave 2.

The gap between them is your setup window, and it is not as long as it looks once you account for cleaning up data, configuring your accounting system, and testing.

Finding your deadline

To place yourself on the timeline:

• Do you invoice other businesses or government (B2B/B2G)? If yes, assume you’re in scope. It depends on your transactions, not your VAT status. (See who e-invoicing applies to.)
• What’s your annual revenue relative to AED 50M? That sorts you into Wave 1 (over) or Wave 2 (under).
• Work backwards from go-live. Give yourself a comfortable runway before the hard date, not the week before.

Why you shouldn’t wait for the deadline

Two reasons. First, the work takes longer than expected: data cleanup and system testing always do. Second, missing the deadline isn’t free: non-compliance carries monthly penalties, which we cover in what happens if you miss the deadline. Starting early turns a stressful scramble into a calm checklist.
