In short

E-invoicing in the UAE applies to every person doing business in the country, whether or not it is registered for VAT, unless the person or the transaction is specifically excluded. A business in scope that is not registered for any tax must register with the Federal Tax Authority (FTA) to obtain a Tax Identification Number (TIN), and each business exchanges its e-invoices through a single accredited service provider (ASP) chosen from the Ministry of Finance list. Under the Ministry of Finance's timeline as of October 2026, a business with revenue of AED 50 million or more has an ASP appointment deadline of 30 October 2026 and a go-live date of 1 January 2027, while a business with revenue below AED 50 million has an appointment deadline of 31 March 2027 and a go-live date of 1 July 2027. A PDF sent by email is not an e-invoice, and supplies to or from individuals who are not in business are outside the scope. Cabinet Decision No. 173 of 2026 sets the penalties, starting at AED 5,000 for not implementing e-invoicing, which includes not appointing an ASP.

Does e-invoicing apply to a business that is not registered for VAT?

Yes. The Ministry of Finance's UAE Electronic Invoicing Guidelines say e-invoicing is mandatory for any person conducting business in the UAE, regardless of their VAT registration status, unless specifically excluded.

Your e-invoicing identifier is your TIN. A business registered with the FTA for any tax already has one: the first 10 digits of its Tax Registration Number (TRN). A business in scope that is not required to register for any tax must register with the FTA to obtain a TIN, which it generates through EmaraTax.

Without VAT registration, a business issues commercial invoices rather than tax invoices, and its PDF or paper commercial invoices must be replaced by e-invoices. An investment holding company with only passive income and no business transactions is not in scope, but recharging management or other costs counts as a business transaction.

When must my business appoint an ASP and go live?

A pilot began on 1 July 2026, and any business may implement e-invoicing voluntarily from that date. The mandatory deadlines depend on revenue: gross income in the most recent accounting period, based on its financial statements or, if there are none, other documentation the FTA accepts.

As of October 2026, under Ministerial Decision No. 244 of 2025 as amended by Ministerial Decision No. 66 of 2026, the deadlines are:

  • Revenue of AED 50 million or more: ASP appointment deadline 30 October 2026, go-live 1 January 2027. The appointment deadline was moved from 31 July 2026 in May 2026, and version 2.0 of the guidelines, dated 26 October 2026, shows the new date.
  • Revenue below AED 50 million: ASP appointment deadline 31 March 2027, go-live 1 July 2027.
  • Government entities: ASP appointment deadline 31 March 2027, go-live 1 October 2027.

The guidelines also say that a newly established business within the scope must appoint an ASP and complete onboarding before issuing its first invoice, whatever its date of establishment.

Is a PDF invoice sent by email an e-invoice?

No. The Ministry of Finance says unstructured formats such as PDF, Word documents, images, scanned copies and emails are not e-invoices. An e-invoice is structured data in XML format, with no QR code or barcode, exchanged between supplier and buyer and reported electronically to the FTA.

The supplier's ASP validates the invoice data, converts it into the UAE standard XML format if needed and sends it to the buyer's ASP, and the tax data is reported to the FTA through the ASPs. The Ministry says this will allow certain VAT return fields to be pre-populated.

A PDF still has a role during the transition: when invoicing a buyer that has not yet implemented e-invoicing, a regular tax invoice, such as a PDF, is required in addition to the electronic tax invoice.

Do sales to consumers need e-invoices?

No. Supplies to or from natural persons who are not in business are outside the scope of e-invoicing, and no e-invoice is needed for a supply to a consumer. Ministerial Decision No. 244 of 2025 adds that business-to-consumer transactions, and a person engaged only in them, are not subject to the system until the Minister decides otherwise.

Sales to businesses and government entities are in scope, including tendered government contracts, so a business that sells mainly to consumers still needs e-invoices for its business customers.

What changed on 1 October 2026?

Ministerial Decision No. 197 of 2026 amended Ministerial Decision No. 243 of 2025 from 1 October 2026, with the Ministry citing reduced operational burdens on businesses. The main changes are:

  • Transactions between members of the same VAT group are excluded for 24 months from 1 January 2027. The guidelines call this a temporary grace period that affects only the timing of compliance.
  • The general deadline for issuing e-invoices and electronic credit notes is now 14 business days after the transaction, instead of 14 days. VAT registrants still follow the VAT Law timeline.
  • Records must be kept for the Tax Procedures Law period and be capable of being produced to the FTA on request, and the requirement to store them in the UAE has gone.
  • The duty to notify the FTA of a system failure within 2 business days has been removed.

Which transactions are excluded?

Excluded transactions have no exchange and reporting requirement. The guidelines add that financial services which would be standard rated for resident customers are not excluded just because they are zero-rated exports. A business may still issue e-invoices for excluded transactions voluntarily, and the rules then apply in full, except the penalty decisions.

As of October 2026, the excluded transactions are:

  • sovereign transactions by government entities that are not in competition with the private sector
  • international passenger flights where the airline issues an electronic ticket, and ancillary services covered by an Electronic Miscellaneous Document
  • international carriage of goods by an airline under an airway bill, for 24 months from the date the e-invoicing system becomes effective
  • financial services that are exempt from VAT or zero rated under Article 42 of the VAT Executive Regulation
  • transactions between members of the same VAT group, for 24 months from 1 January 2027
  • any other transaction the Minister determines

How quickly must an e-invoice be issued?

As of October 2026, within 14 business days of the date of the business transaction, which is the earlier of the date it occurred and the date payment was received. Business days exclude weekends and official federal government holidays. The same deadline applies to electronic credit notes. For VAT registrants the rule is subject to the timeline in the VAT Law, which generally requires a tax invoice within 14 days of the date of supply.

How do I choose an ASP, and can I use more than one?

You can use only one. The Ministry's guidelines say a business in scope must appoint only one ASP, for both sending and receiving e-invoices. Ministerial Decision No. 243 of 2025 requires recipients, as well as issuers, to appoint an ASP. In a VAT group, each member has its own TIN and may use a different ASP.

Providers are chosen from the Ministry of Finance list of accredited service providers, which is updated as new providers are accredited. The guidelines say the contract must be finalised before onboarding, and that the business itself, not the ASP, starts onboarding through the FTA's EmaraTax system. The Ministry's suggested questions for choosing a provider include:

  • Can it integrate with your ERP, accounting or invoicing systems?
  • Is the data stored in the UAE or overseas?
  • Which compliance certifications and security measures does it have?
  • What are its support response times and uptime service levels?
  • What is the pricing model, and are there hidden fees?
  • Does the contract include the 100 free e-invoice exchange and reporting services a year that each provider commits to under Ministerial Decision No. 168 of 2026?

How do self-billing and credit notes work?

Self-billing, where the buyer issues the invoice on the supplier's behalf, is allowed only where both are VAT registrants, so commercial invoices cannot be self-billed. The buyer must be on the e-invoicing system, and once the supplier's mandatory date arrives its self-billed sales need e-invoices too. The guidelines therefore suggest checking self-billing arrangements, because a customer may not yet be required to implement e-invoicing.

Every provisional invoice should be an e-invoice, adjusted later by an electronic credit note or an additional e-invoice. An electronic credit note is required where:

  • the transaction is cancelled
  • the agreed consideration is reduced for any reason
  • the consideration is returned in full or in part
  • an administrative or numerical error has occurred

How long must e-invoices be kept, and must they stay in the UAE?

Since 1 October 2026, everyone subject to the system must keep all e-invoices, electronic credit notes and associated data for the period set by the Tax Procedures Law and be able to produce them to the FTA on request. The Ministry says the amendment removed the requirement to store the data in the UAE, shifting the focus from where records are stored to their retention and accessibility.

The standard periods below come from the Tax Procedures rules, as summarised in the guidelines, and apply unless a tax law states otherwise. The Corporate Tax Law, for example, requires a taxable person to keep records for 7 years after the end of the tax period. A further 4 years can apply during a dispute with the FTA or a tax audit, or after notice of an intended audit. The standard periods are:

  • 5 years after the tax period the records relate to, for a taxable person
  • 5 years from the end of the calendar year the document was created, for anyone else
  • 7 years from the end of the calendar year the document was created, for real estate records

What are the penalties?

Cabinet Decision No. 173 of 2026 sets the penalties and replaces Cabinet Decision No. 106 of 2025. The Ministry of Finance announced it on 30 October 2026. It comes into force the day after it is published in the Official Gazette, and the copy on the Ministry's website does not show its date of issue. The penalties are:

  • Not implementing e-invoicing, including not appointing an accredited service provider, or a recipient not staying compliant after implementing it: AED 5,000 for the first violation, then AED 5,000 for each month or part of a month it continues, up to a total of AED 50,000 in any 12 consecutive months.
  • Not issuing and sending an e-invoice through the system: AED 100 for each e-invoice, up to AED 5,000 a calendar month.
  • Not issuing and sending an electronic credit note through the system: AED 100 for each credit note, up to AED 5,000 a calendar month.
  • Not telling your accredited service provider about changes to the data registered with the FTA: AED 250 for each day or part of a day, up to AED 5,000 a calendar month.

Where the same person acts as issuer, recipient or both in the same violation, only one penalty applies for that violation. The decision does not apply to e-invoices issued voluntarily, and the Ministry's guidelines say that keeping to the roll-out timelines, which include the last date for appointing an ASP, is essential to avoid potential penalties. The usual tax penalties can also apply where compliant tax invoices are not issued or kept.

Frequently asked questions

What is the penalty for not appointing an ASP on time?

Under Cabinet Decision No. 173 of 2026, failing to appoint an ASP counts as failing to implement e-invoicing. The penalty is AED 5,000 for the first violation, then AED 5,000 for each month or part of a month it continues, up to a total of AED 50,000 in any 12 consecutive months.

Does a business that only buys need an ASP?

Often, yes. Ministerial Decision No. 243 of 2025 requires recipients of e-invoices, as well as issuers, to appoint an ASP, and a business appoints one ASP for both sending and receiving. A business that sells only to consumers is not subject to the system until the Minister decides otherwise, and a holding company with only passive income and no business transactions is not in scope.

Do I need a new tax number for e-invoicing?

Not if you are registered with the FTA for any tax: your TIN is the first 10 digits of your TRN. A VAT group member uses its own TRN, not the group representative's.

Can I start e-invoicing early?

Yes. Any business may implement it voluntarily from 1 July 2026, meeting the Ministry's and the FTA's technical requirements. E-invoicing penalties do not apply to e-invoices issued voluntarily, and the guidelines say the voluntary phase allows testing without the risk of penalties for failing to meet mandatory requirements. The mandatory deadlines, including the last date for appointing an ASP, still apply.

Does e-invoicing apply to a business established outside the UAE?

It can. It applies to any person conducting business in the UAE, whether or not established there, and a non-resident that must issue tax invoices under the VAT law should issue them as e-invoices.
