When does e-invoicing start in UAE? Every date, by type of business

Ministerial Decision No. 244 of 2025 phases the rollout by revenue and type of entity. Ministerial Resolution No. 66 of 2026 later moved the provider appointment deadline for the largest businesses from 31 July 2026 to 30 October 2026, without moving the go-live date.

• Revenue of AED 50 million or more: appoint a provider by 30 October 2026; go live 1 January 2027
• Revenue below AED 50 million: appoint by 31 March 2027; go live 1 July 2027
• Government entities: appoint by 31 March 2027; go live 1 October 2027
• Anyone: voluntary adoption from 1 July 2026

Revenue for the threshold is the gross income for the most recent accounting period, based on financial statements prepared under UAE rules. If those are not available, documentation acceptable to the FTA is used instead.

Example: a Dubai IT distributor's audited statements for 2025 show revenue of AED 52 million. It is in the first phase, even if 2026 revenue drops to AED 47 million. A company with AED 49.5 million in its latest statements is in the second phase, with until 1 July 2027.

With the appointment deadline of 30 October 2026 days away, a first-phase business that has not signed with a provider is late in practical terms. Contract with an accredited provider now, complete onboarding through EmaraTax as the FTA requires, and spend November and December testing.

Late implementation, including a late provider appointment, is a penalised violation. Penalties are now set by Cabinet Decision No. 173 of 2026, which replaced Cabinet Decision No. 106 of 2025, so check the Ministry of Finance e-invoicing page for the current amounts.

Second-phase businesses have more time, but not as much as it seems. Providers will be busy with first-phase clients until early 2027. A sensible plan is to clean data in late 2026, shortlist providers in January, sign in February and test from April, leaving a margin before 1 July 2027.

Example: a Sharjah building materials trader with revenue of AED 18 million and 600 business customers. Most of its effort will go into customer data, since a third of its customer records lack a TRN or full address.

• Q4 2026: clean customer and product data
• January 2027: shortlist accredited providers
• By 31 March 2027: sign and appoint
• April to June 2027: onboard and test
• 1 July 2027: go live

The rules have already been amended several times in 2026, including Ministerial Decision No. 197 of 2026, which added a temporary exclusion for transactions between members of the same tax group and removed the system failure reporting duty. More adjustments are possible.

Business-to-consumer transactions remain excluded until the Minister sets a date. Watch the Ministry of Finance e-invoicing page rather than relying on dates repeated in older articles.

Some owners read 1 July 2027 as the date to start preparing. It is the date the system must work. Others assume a company that is not VAT registered is outside the rules; the scope in Ministerial Decision No. 243 of 2025 is written around persons conducting business, not VAT registration.

A third misreading is that the first phase means large companies only, so suppliers to them can relax. In practice, a large customer going live on 1 January 2027 may start asking its smaller suppliers about their own readiness, because it will be receiving e-invoices through its own provider.

Whichever phase you are in, the provider will only be as good as the data you give it. HelloBooks keeps customer TRNs, addresses and VAT treatment on every invoice line, and the AI agent can list customers whose records are incomplete. Ask 'which business customers have no TRN on file?' and you get a working list to clean up.

HelloBooks does not send e-invoices or connect to providers; you appoint an accredited provider from the Ministry of Finance list. Our team can help you prepare data exports or custom invoice fields your provider asks for if you book a call at /book-a-demo.
