Key takeaways
- Phase one: businesses with revenue of AED 50 million or more go live on 1 January 2027.
- Phase two: businesses with revenue under AED 50 million appoint an ASP by 31 March 2027 and go live on 1 July 2027.
- Business-to-consumer (B2C) transactions stay outside the system until a further ministerial decision.
- An e-invoice is structured data exchanged between accredited providers, not a PDF sent by email.
- E-invoicing applies whether or not you are registered for value added tax (VAT), so check your position either way.
The e-invoicing timeline at a glance
The dates come from Ministerial Decision No. 244 of 2025 on the implementation of the electronic invoicing system, issued by the Ministry of Finance (MoF). The rollout is phased by revenue, so the first thing to establish is which group your business falls into.
The decision also set an earlier date for the larger group to appoint its provider. The Ministry later moved that appointment date once, called the change a final adjustment and confirmed that the 1 January 2027 go-live date and every other deadline stay as they are. If you are in the larger group and have not yet appointed a provider, make that your first step.
Businesses that want to start early can adopt the system voluntarily ahead of their phase, as long as they meet the technical requirements.
- Revenue of AED 50 million or more: e-invoicing live from 1 January 2027.
- Revenue below AED 50 million: appoint an ASP by 31 March 2027 and go live by 1 July 2027.
- Government entities: a separate timetable set in the same decision.
- Business-to-consumer transactions: excluded until the Minister decides otherwise.
How to tell which phase you are in
The decision measures revenue as the gross income earned in your most recent accounting period, based on your financial statements. Where financial statements are not available, the Federal Tax Authority (FTA) may accept other documentation it considers acceptable.
Use your final accounts rather than management estimates, and keep a note of the figure you relied on. If you own more than one company, look at each one's accounts separately; do not assume every entity falls into the same phase.
A business that sells only to consumers is outside the system for now. If you sell to both consumers and businesses, the business side of your sales is in scope, and that is what you plan for.
What counts as an e-invoice
Under the UAE system, an electronic invoice is an invoice in a structured electronic format that allows automatic processing. The Ministry's guidelines say e-invoices are issued, transmitted and received in XML, a machine-readable data format, and travel between businesses through accredited providers.
A PDF is not an e-invoice, and neither is a scanned paper invoice. Once you are live, PDF or paper invoices for in-scope transactions are replaced by electronic ones. Where your customer is not yet on the system, the guidelines say a regular tax invoice, for example a PDF, is still needed alongside the electronic one.
Credit notes move onto the system as well. When a sale is reduced and output tax falls, you issue an electronic tax credit note through the same channel, and one credit note can refer to one or several original invoices.
Which transactions are in scope
The guidelines bring business-to-business (B2B), business-to-government (B2G), government-to-business and government-to-government transactions into the system. Supplies to or from individuals who are not acting in business fall outside it.
There are a few exclusions, including sovereign activities of government entities, certain airline supplies and VAT-exempt financial services of the kind listed in the VAT Executive Regulation. Other VAT-exempt supplies are not excluded; they are invoiced electronically using the exempt tax category.
Most importantly for smaller firms, the guidelines make e-invoicing mandatory for any person doing business in the UAE, regardless of VAT registration. A business below the VAT threshold that sells to other businesses should not assume the rollout passes it by.
What an Accredited Service Provider does
An ASP is a service provider granted accreditation to provide electronic invoicing services in the UAE. The UAE uses a decentralised exchange known as the five-corner model: your ASP validates your invoice data, converts it to the UAE XML standard where needed, sends it to your customer's ASP and reports the tax data to the FTA.
The ASP runs the exchange, but the compliance obligation stays with you as the supplier, or with the buyer where invoices are self-billed. You select and onboard with your chosen ASP through EmaraTax, the FTA's digital platform, and you must keep the ASP informed when your circumstances change, for example when you register or deregister for VAT, join or leave a tax group, or close the business.
Choosing an ASP is a technology decision as much as a tax one. Ask how it connects to your accounting or enterprise resource planning (ERP) system, how it reports rejected invoices back to you, how it handles credit notes and what support it gives around your go-live.
How e-invoicing fits with your VAT position
E-invoicing changes how invoices are issued and exchanged, not the VAT rules themselves. VAT is charged at 5%. Registration is mandatory once your taxable supplies and imports exceed AED 375,000, measured over the look-back and look-ahead periods the FTA sets, and voluntary registration is open above AED 187,500.
Amendments to the VAT law came into force on 1 January 2026. They focused on procedures such as refunds and input tax recovery, and the 5% rate and the registration thresholds stayed the same. Because the detail has moved, we check the rules that apply to you before advising on any VAT step.
Make sure your VAT and trade license details on EmaraTax are accurate before you onboard with an ASP. Your provider relies on the same identifiers, and a mismatch between your license, your VAT record and your invoice data is one of the easiest problems to prevent.
What to do now: a preparation checklist
Start with the steps that depend only on you, such as data clean-up and process mapping. They take the longest to fix, and they are the steps no provider can do for you.
- Confirm your revenue for the most recent accounting period and note which phase applies.
- List every invoice type you issue: tax invoices, commercial invoices, credit notes and self-billed invoices.
- Clean your customer records, including legal names, addresses and tax registration numbers.
- Check whether your accounting or ERP system can produce the structured data your ASP needs.
- Shortlist and appoint an ASP, then onboard through EmaraTax.
- Update your FTA records so your VAT and trade license details match what your invoices show.
- Train the people who raise invoices and handle rejections, and test the full flow before your go-live date.
Common mistakes, and where we fit in
The same few assumptions cause most of the late scrambles. Check that none of these apply to you:
Global Sky PRO works on the FTA side of the change. We prepare and submit VAT registrations, update your FTA registration details on EmaraTax and help keep your trade license and tax records consistent, so your ASP onboarding starts from clean data. The technical exchange is run by your chosen ASP, and the FTA makes every decision on registrations and compliance. Our service fee is agreed in writing before we start and is kept apart from any government fees, which are paid at cost.
- Expecting PDF invoices sent by email to remain acceptable after go-live.
- Treating businesses that are not VAT registered as outside e-invoicing.
- Using estimates instead of financial statements to decide the phase.
- Forgetting credit notes and self-billed invoices when planning the switch.
- Leaving the ASP's records out of date after a VAT, tax group or ownership change.
