UAE E-Invoicing: Deadlines, Scope and What SMEs Must Do Before 2027

What is UAE e-invoicing?

UAE e-invoicing replaces PDF and paper invoices between businesses with structured electronic invoices exchanged through accredited service providers. The supplier's system sends the invoice data to its ASP, the ASP delivers it to the buyer's ASP, and the invoice data is reported to the Federal Tax Authority. The Ministry of Finance publishes the list of pre-approved ASPs and updates it from time to time.

The framework is set out in Ministerial Decision No. 243 of 2025 on the Electronic Invoicing System and Ministerial Decision No. 244 of 2025 on its implementation, issued in September 2025. Ministerial Decision No. 66 of 2026, issued in May 2026, extended the date by which large businesses must appoint an ASP. The exchange model is based on the Peppol network, using a UAE data specification, so invoices are machine-readable data rather than documents.

What are the deadlines?

The rollout is phased by revenue. A business with revenue of AED 50 million or more had to appoint an ASP by 30 October 2026 and must issue e-invoices from 1 January 2027. A business with revenue below AED 50 million must appoint an ASP by 31 March 2027 and must issue e-invoices from 1 July 2027. Government entities must appoint an ASP by 31 March 2027 and go live on 1 October 2027.

A pilot with selected businesses started on 1 July 2026, and any business could start using e-invoicing voluntarily from that date. The Ministry of Finance has said it does not intend to extend the 30 October 2026 date further. Check the Ministry's e-invoicing page for the current position before you plan, because implementation details are still being issued.

Who is in scope, and what is excluded?

The decisions apply to persons conducting business in the UAE for their business-to-business and business-to-government transactions. Business-to-consumer transactions are excluded until further notice. Confirm whether your entity is in scope on its own facts, especially if it is not registered for VAT or carries on only limited activity in the UAE.

Some transactions are excluded, including government activities carried out in a sovereign capacity, certain international passenger transport and related airline services, international transport documented by airway bills for a temporary period, and exempt or zero-rated financial services. If most of your sales fall into one of these categories, check the exclusion wording carefully rather than assuming the whole business is outside the system.

What changes in day-to-day invoicing?

E-invoices and electronic credit notes have to be issued within 14 days of the transaction, through the ASP. Your accounting or ERP system must either connect to the ASP directly or export invoice data in the format the ASP needs. Customer master data becomes critical: each buyer's legal name, Tax Registration Number (TRN) and other identifiers have to be correct, because a rejected invoice is a rejected invoice.

There are also operational duties. E-invoice data must be stored in the UAE, technical failures that stop you issuing e-invoices have to be reported to the Federal Tax Authority within two business days, and changes to your registered data have to be notified to your ASP within five business days. Administrative penalties apply for failing to meet the obligations, so treat the go-live date as a hard deadline.

What if your accounts are kept by a team in India?

Many Gulf businesses run their billing and bookkeeping from a back office or subsidiary in India. That model still works under e-invoicing, but three things need attention. First, the ERP or accounting system the Indian team uses must connect to the UAE ASP and produce compliant invoices. Second, check where the system stores e-invoice data, because it must be held in the UAE. Third, decide who in the team owns rejected invoices and data corrections, so the 14-day and five-day timelines are met.

This is also a good moment to look at the wider set-up. A UAE company whose key decisions are effectively taken in India can raise place of effective management (POEM) questions in India and residence questions under UAE corporate tax, and services provided by an Indian group company to the UAE company need transfer-pricing support. E-invoicing will not create those issues, but the review it forces is a sensible time to document how the two entities actually work.

Readiness checklist for an SME

1. Confirm your phase

   Check whether your revenue puts you in the first group (AED 50 million or more) or the second, and note your ASP and go-live dates.

2. Choose an ASP

   Shortlist providers from the Ministry of Finance list and check that they connect to your accounting or ERP system.

3. Clean customer data

   Verify every customer's legal name, TRN and address so invoices are not rejected.

4. Map the invoice flow

   Decide who raises invoices and credit notes, who handles rejections and how the 14-day issue window is met, including any team in India.

5. Check data storage

   Confirm that e-invoice data is stored in the UAE and that your archive and backups meet that rule.

6. Test before go-live

   Run test invoices through the ASP well before your go-live date and fix mapping errors early.
