What changed in UAE e-invoicing in October 2026?
Two official updates landed within a week of each other, about ten weeks before the first businesses must switch over.
- Ministerial Decision No. 197 of 2026, announced by the Ministry of Finance on 19 October 2026, amends the main e-invoicing decision (Ministerial Decision No. 243 of 2025) with effect from 1 October 2026.
- Version 2.0 of the Electronic Invoicing Guidelines, published later that month for sellers, buyers and Accredited Service Providers (ASPs), with a new appendix on identification and invoice classification.
1 Jan 2027
Phase 1 go-live
AED 50m
Phase 1 revenue threshold
14 business days
new issuing deadline
31 Mar 2027
Phase 2 ASP deadline
None of this delays the start date. The phased mandate still begins on 1 January 2027, starting with businesses whose revenue is above AED 50 million.
What does Ministerial Decision No. 197 of 2026 change?
The decision makes four practical changes:
| Area | What the rule is now |
|---|---|
| Issuing deadline | An e-invoice or e-credit note must be sent through the system within 14 business days, counted from the earlier of the transaction date or the date payment is received. VAT-registered issuers keep following the VAT law timeline. |
| VAT tax groups | Transactions between members of the same tax group are excluded from e-invoicing for 24 months from 1 January 2027. |
| Data storage | The requirement to keep e-invoices and related data inside the UAE has been removed. Records must still be kept for the period set by the Tax Procedures Law and given to the FTA on request. |
| System failures | Businesses no longer have to notify the FTA when their system fails. The previous two-business-day notification rule is repealed. |
Who has to e-invoice, and when?
The rollout is phased by revenue. B2B and B2G transactions are in scope first; B2C invoices are out of scope until a later phase is announced, but B2C sales still count when you work out your revenue.

What do the new guidelines (version 2.0) say?
Version 2.0 of the guidelines clarifies how invoices must be filled in. The points most businesses will notice:
- Seller identification. VAT-registered sellers use their 15-digit Tax Registration Number (TRN). Sellers that are not VAT-registered use a 10-digit Tax Identification Number (TIN). One of the two is mandatory.
- Buyer identification. The buyer’s legal registration identifier is mandatory for some invoice types and conditional for others, so your customer records need to hold it.
- Invoice type code 480 is only for supplies entirely outside the scope of VAT. Exempt and zero-rated supplies cannot use it.
- Healthcare and insurance. When an insurer only pays a patient’s costs, the patient remains the recipient. The insurer is the buyer only when it receives its own in-scope supply.
- New businesses must appoint an ASP and complete onboarding before issuing their first invoice, whenever they were set up.
What are the penalties?
Penalties are set by Cabinet Decision No. 106 of 2025. The main ones:
| Violation | Penalty |
|---|---|
| Not implementing the system or not appointing an ASP on time | AED 5,000 for each month (or part of a month) of delay |
| Not issuing or sending an e-invoice or e-credit note on time | AED 100 per document, up to AED 5,000 per calendar month |
| Not telling your ASP about changes to your registered data on time | AED 1,000 per day of delay |
The penalty for not reporting a system failure on time has lost its practical relevance now that Ministerial Decision No. 197 of 2026 removed the duty to notify the FTA of system failures. Penalties can change, so confirm the current list with your tax adviser or the Ministry of Finance.
What should your business do now?
E-invoicing readiness
0/8 done
For many small and mid-sized businesses the hard part is not the law but the plumbing: online stores, booking systems and custom apps that create invoices outside the accounting package. Each of those needs to send its invoice data to the ASP, or hand it to an accounting system that does.
Frequently asked questions
When does e-invoicing become mandatory in the UAE?
From 1 January 2027 for businesses with annual revenue of AED 50 million or more, from 1 July 2027 for other in-scope businesses, and from 1 October 2027 for government entities.
Is a PDF invoice still valid after e-invoicing starts?
Not for in-scope transactions. In-scope B2B and B2G invoices must be issued as structured e-invoices through an Accredited Service Provider (ASP).
Do B2C invoices need to be e-invoices?
Not yet. B2C transactions are outside the mandate until a later phase is announced, but B2C revenue still counts towards your revenue threshold.
What is Ministerial Decision No. 197 of 2026?
It amends Ministerial Decision No. 243 of 2025 on the e-invoicing system. It sets a 14-business-day issuing deadline, excludes tax-group transactions for 24 months, removes the UAE data-storage requirement and the duty to report system failures.
What happens if I miss my ASP deadline?
Under Cabinet Decision No. 106 of 2025, failing to implement the system or appoint an ASP on time carries a penalty of AED 5,000 for each month or part of a month of delay.
Do I need e-invoicing if my business is not VAT-registered?
Scope depends on the transaction, not only VAT registration. Non-VAT-registered sellers in scope identify themselves with a 10-digit TIN. Check your position with a tax adviser.
