When Does E-Invoicing Become Mandatory in the UAE? Deadlines, Phases, and the October 2026 Changes
UAE e-invoicing becomes mandatory on 1 January 2027 for businesses with revenue of AED 50 million or more, 1 July 2027 for other in-scope businesses and 1 October 2027 for government entities. Large businesses had to appoint an Accredited Service Provider (ASP) by 30 October 2026. Everyone else in scope must appoint one by 31 March 2027.
If you run a business in the UAE, you have probably seen these UAE e-invoicing deadlines quoted in different ways. This guide gives you the dates as they stand under the current law, including the October 2026 changes. You will also see what to do if a deadline has already passed.
KEY TAKEAWAYS
- Your revenue decides your date. AED 50 million or more means 1 January 2027. Below that means 1 July 2027.
- The ASP deadline for large businesses was 30 October 2026. If you missed it, appoint a provider now, as penalties can apply after that date.
- October 2026 brought four changes:a temporary VAT Tax Group exclusion, a 14 business day issuing window, permission to store records outside the UAE and the removal of the system-failure rules.
- The penalties decision has changed.Cabinet Decision No. 173 of 2026 replaces Cabinet Decision No. 106 of 2025.
- Nothing has been delayed. No go-live date moved in 2026.
UAE E-Invoicing Deadlines at a Glance
Your UAE e-invoicing deadline depends on your revenue. Businesses with AED 50 million or more go live on 1 January 2027, and smaller in-scope businesses go live on 1 July 2027.
Implementation Phases
Ministerial Decision No. 243 of 2025 sets the rules and scope of the system. Ministerial Decision No. 244 of 2025 sets the phases and dates.

|---|---|---|---|
| Voluntary | Any business that wants to start early | Not applicable | Open since 1 July 2026 |
| Phase 1 | Revenue of AED 50 million or more | 30 October 2026 (extended from 31 July 2026) | 1 January 2027 |
| Phase 2 | Other in-scope businesses (below AED 50 million) | 31 March 2027 | 1 July 2027 |
| Phase 3 | Government entities | 31 March 2027 | 1 October 2027 |

Important E-Invoicing Dates
Two dates matter for every business. The ASP date is when you must sign up with an approved provider. The go-live date is when you must actually send and receive e-invoices through it.
| Date | What happens |
|---|---|
| 1 July 2026 | Voluntary adoption opens |
| 1 October 2026 | Ministerial Decision No. 197 of 2026 takes effect (announced 19 October 2026) |
| 30 October 2026 | Phase 1 ASP deadline |
| 1 January 2027 | Phase 1 go-live and start of the VAT Tax Group exclusion |
| 31 March 2027 | Phase 2 and Phase 3 ASP deadline |
| 1 July 2027 | Phase 2 go-live |
| 1 October 2027 | Phase 3 go-live (government entities) |
| 31 December 2028 | VAT Tax Group exclusion ends |
Revenue Below AED 50 Million? Your Deadline Is 31 March 2027
If your revenue is below AED 50 million, you must appoint an ASP by 31 March 2027 and start e-invoicing on 1 July 2027. Most small and medium-sized UAE businesses fall into this phase. ERP changes, onboarding and testing usually take several months, so start planning now rather than in March.
These points catch many smaller businesses out:
1. Mixed B2B and B2C sales: Count all your revenue when you check the threshold. Only your B2B and B2G invoices need to be e-invoices.
2. Not VAT registered: E-invoicing can still apply. The rules cover businesses making B2B or B2G sales in the UAE, whether or not they are VAT registered.
3. Free zone and mainland companies: Both are covered if they make B2B or B2G sales.
4. New businesses: Under version 2.0 of the MoF guidelines, a new business within mandatory scope must appoint an ASP and complete onboarding before it issues its first invoice.
You can also start early in the voluntary phase. Businesses that join voluntarily before their phase begins are not penalised.
Missed the 30 October ASP Deadline? What to Do Now
If your revenue is AED 50 million or more and you have not appointed an ASP, Appoint an accredited provider now. Updated penalties, which replace Cabinet Decision No. 106 of 2025, set a fine of AED 5,000 for the first violation, plus AED 5,000 for each month or part of a month it continues. Total fines are capped at AED 50,000 in any 12 consecutive months. A tax adviser can confirm how this applies to your dates.
Example: At the AED 5,000 rate, a Phase 1 business that appoints its ASP on 15 December 2026 is one full month and part of a second month late. That could mean AED 10,000 in penalties. Ask your adviser to confirm the figure for your own dates.
Your go-live date of 1 January 2027 has not moved, so you also have less time to test. Take these four steps this week:
1. Appoint an ASP. Choose from the official list on the Ministry of Finance e-invoicing portal, then select and onboard with your provider through the FTA’s EmaraTax platform.
2. Agree on a go-live plan. Ask the provider for an onboarding and testing schedule that ends before 1 January 2027.
3. Keep your paperwork. Save the signed agreement and the date you appointed the provider.
4. Get your exposure checked. A tax adviser can confirm how penalties apply to your dates
Who Must Comply With UAE E-Invoicing?
Any business that invoices another business (B2B) or a government body (B2G) in the UAE must use e-invoicing. Sales to consumers (B2C) are outside the rules for now.
1. How Your Revenue Is Measured
Revenue means your gross income for your most recent accounting period, based on your financial statements. If you have no financial statements, other documents accepted by the Federal Tax Authority (FTA) can be used. This definition comes from Ministerial Decision No. 244 of 2025.
2. Two Groups That Are Often Missed
- Non-resident suppliers: A foreign business that must issue UAE tax invoices must issue e-invoices too, so it also needs an ASP.
- Suppliers whose buyers are not ready: You must still issue the e-invoice. Under the MoF Electronic Invoicing Guidelines, you also send a regular tax invoice, such as a PDF, during the transition.
3. Which Transactions Are Excluded?
| Excluded item | What it means |
|---|---|
| B2C sales | Sales to consumers. A business that sells only to consumers is outside scope. |
| VAT Tax Group deals | Deals between members of the same VAT Tax Group, from 1 January 2027 to 31 December 2028. |
| Sovereign government transactions | Transactions by government entities acting in a sovereign capacity that do not compete with the private sector. |
| Goods that never enter the UAE | Goods supplied from one place outside the UAE to another, treated as out of scope under version 2.0 of the MoF guidelines. |
| International air passenger transport | Airline passenger tickets issued as e-tickets, and services sold directly to passengers. |
| International air cargo | Goods carried by airline under an airway bill, for 24 months from go-live. |
| Certain financial services | Financial services that are VAT exempt or zero-rated. |

Get Expert Tax SupportWhat Is an Accredited Service Provider (ASP)?
An ASP is a Ministry of Finance accredited company that sends and receives your e-invoices and reports the data to the FTA. You cannot e-invoice in the UAE without one.
The UAE uses the Peppol network and a five-corner model:
- You create the invoice.
- Your ASP checks it and converts it to the UAE format (PINT AE).
- Your buyer’s ASP receives it.
- Your buyer gets the invoice.
- The FTA receives the tax data at the same time.
A PDF or scanned copy is not an e-invoice. The invoice must be a structured electronic file sent through an ASP.
ASP accreditation is now governed by Ministerial Decision No. 168 of 2026, which removed the earlier pre-approval stage. Choose your provider from the official list on the Ministry of Finance e-invoicing portal, then onboard through the FTA’s EmaraTax platform. If you are VAT registered, see Tax24’s VAT services in the UAE to see how e-invoicing links to your VAT returns.
What Changed in UAE E-Invoicing Rules in 2026?
Two decisions changed the rules in 2026, and neither moved a go-live date. In May, the Phase 1 ASP deadline was extended. In October, Ministerial Decision No. 197 of 2026 made four practical changes.
1. May 2026: Phase 1 ASP Deadline Extended to 30 October
Ministerial Decision No. 66 of 2026 moved the Phase 1 ASP deadline from 31 July 2026 to 30 October 2026. That deadline has now passed, and the 1 January 2027 go-live date stays the same.
2. October 2026: Four Changes Under Ministerial Decision No. 197 of 2026
The Ministry of Finance announced Ministerial Decision No. 197 of 2026 on 19 October 2026, with effect from 1 October 2026. It amends Ministerial Decision No. 243 of 2025, the main e-invoicing rulebook.
Key E-Invoicing Changes in October 2026
| Change | What the rule now says | What it means for you |
|---|---|---|
| 1. VAT Tax Group exclusion | Deals between members of the same VAT Tax Group are excluded for 24 months from 1 January 2027. | Set up your ERP to treat internal group deals and outside deals differently. |
| 2. 14 business day window | You have 14 business days from the transaction date to issue and send an e-invoice or credit note (previously 14 calendar days). | Weekends and public holidays no longer count. VAT-registered businesses should still check the VAT Law timing rules. |
| 3. Storage outside the UAE | E-invoice data no longer has to be stored "within the State". | Keep records for the Tax Procedures Law period (generally five years, seven for real estate) and show them to the FTA on request. |
| 4. System-failure rules removed | The duty to notify the FTA within two business days of a system failure is repealed. | The related penalty has also been removed under the updated penalty rules. Ask your ASP how it handles outages. |
Penalties apply once the ASP deadline for your phase has passed. Businesses using e-invoicing voluntarily before their phase begins are not penalised. Fines are AED 5,000 for the first violation, plus AED 5,000 for each month or part of a month it continues, capped at AED 50,000 in any 12 consecutive months. Only one penalty applies to the same violation, even if a business is both the issuer and the recipient.
Has UAE E-Invoicing Been Delayed?
No go-live date has been postponed. The May 2026 decision moved only the Phase 1 ASP deadline, and the October 2026 decision changed specific rules. Version 2.0 of the MoF guidelines, dated 26 October 2026, also left the timeline unchanged.
How to Prepare for UAE E-Invoicing: Six Steps
Start by confirming your phase, then appoint an ASP early enough to test before go-live. Data problems usually show up only during testing, so give yourself months, not weeks.
1. Confirm your phase. Check your revenue for your latest accounting period and whether you make B2B or B2G sales.
2. Review your invoicing setup. Look at your accounting software, ERP and how invoices are created today.
3. Shortlist ASPs. Compare accredited providers on ERP fit, support and pricing.
4. Appoint your ASP. Meet the deadline for your phase and onboard through EmaraTax.
5. Test your invoices. Check invoice data, system links and that you can issue within 14 business days.
6. Train your finance team. Staff should know how to issue invoices, fix errors, raise credit notes and keep records.
