E-invoicing and VAT in the UAE: What Changes and What Does Not.

E-invoicing in the UAE is built on top of VAT, not in place of it. If your business is VAT registered and in scope, your tax invoices and tax credit notes must be issued and sent as structured electronic documents through an Accredited Service Provider. To recover input tax on a purchase that must be e-invoiced, you must keep the e-invoice in line with the system. Your VAT rate, tax periods and VAT return do not change.

This guide covers only the VAT side. For deadlines and first steps, see UAE e-invoicing: what SMEs should do now.

Where e-invoicing sits in the VAT law

Federal Decree-Law No. 16 of 2024 amended the VAT law to support e-invoicing, with effect from 30 October 2024. In the consolidated text published on tax.gov.ae, it changed these parts:

VAT law provision	What it now says
Article 1	A tax invoice includes an electronic invoice, and a tax credit note includes an electronic credit note. New definitions of Electronic Invoicing System, Electronic Invoice and Electronic Credit Note.
Article 55(1)(c)	To recover input tax, you must retain the tax invoice in line with the Electronic Invoicing System where it must be, or has been, issued as an electronic invoice.
Article 65(5)	A registrant subject to the system must issue and transmit tax invoices as electronic invoices.
Article 70(4)	A registrant subject to the system must issue and transmit tax credit notes as electronic credit notes.
Article 76(6)	The FTA can issue a penalty assessment for failing to follow the conditions for electronic tax invoices and credit notes.

Tax invoice or commercial e-invoice?

A PDF, Word file, scan or email is not an e-invoice. The Ministry of Finance lists six e-invoice categories, including self-billed and credit note versions. For most SMEs the key split is this one:

	Electronic tax invoice	Commercial electronic invoice
What it is	The VAT tax invoice, issued in structured form	A structured invoice that is not a VAT tax invoice
Mandatory fields	51	49
Seller identifier	Tax Registration Number (TRN)	Seller tax registration identifier, which may be the Tax Identification Number (TIN) where the seller has no TRN
Buyer details	Includes the buyer's TRN and tax scheme	Includes the buyer's legal registration identifier and its type
AED line amounts	VAT line amount and line total in AED are required	Not in the mandatory list

The practical point: e-invoicing covers business to business and business to government transactions whether or not the seller is VAT registered. A business that is not VAT registered still needs to replace its paper or PDF invoices with e-invoices when its phase starts, and the commercial invoice category does not depend on having a TRN. Both kinds of invoice can mix taxable and non-taxable lines.

Old tax invoice rules that stop applying

Article 59(16) of the VAT Executive Regulation switches off several tax invoice rules once a tax invoice is issued as an electronic invoice, whether the business is required to or does so voluntarily. In plain terms:

• Simplified tax invoices (clauses 2 and 5) no longer apply. For B2B sales in the system, every tax invoice is a full electronic one.
• No invoice for a wholly zero-rated supply (clause 3) no longer applies.
• FTA powers to relax invoice details or waive an invoice (clause 7), and to require a full invoice where a simplified one would do (clause 15), no longer apply.
• The old conditions for issuing a tax invoice "by electronic means" (clause 8) are replaced by the system itself.

Article 60(8) does the same for credit notes, removing the paragraph on showing the original value, correct value and difference, the FTA dispensation and the old electronic means conditions.

Corrections work differently too. The Ministry states that invoices cannot be cancelled, negative invoices are not allowed and debit notes are not permitted. You correct an error with a credit note, which must itself be an electronic credit note where you are in the system. See our glossary entry on the tax credit note.

The 14 day rule and the VAT law timeline

Which time limit governs depends on whether you are VAT registered.

Your position	Deadline to issue and transmit	Counted from
VAT registrant	The VAT law timeline: normally 14 days (VAT law Article 67), with the Executive Regulation exceptions	The date of supply under Articles 25 or 26 of the VAT law
Not VAT registered but in scope	14 days (Ministerial Decision No. 243 of 2025, Article 6(5))	The Date of Business Transaction: the earlier of when the transaction occurred or when payment was received

For a registrant, the date of supply already includes the date payment is received, so the two tests usually land close together.

One change in practice: the Guidelines say that where you receive an advance payment, you issue a tax invoice at that point, and the final invoice covers only the balance.

Input tax recovery under Article 55

Article 55(1) of the VAT law, as amended, lets you deduct recoverable input tax in the first tax period in which all of these are met:

1. You receive and retain a tax invoice with the details of the supply (or the import documents, for imports).
2. You pay the consideration, or part of it, as set out in the Executive Regulation.
3. New: where the tax invoice must be, or has been, issued as an electronic invoice, you retain it in line with the Electronic Invoicing System.
4. Any other condition the Cabinet sets.

If you miss the period in which the conditions are first met, Article 55(2) still lets you claim in a later return.

For a buyer, this means the e-invoice received through your Accredited Service Provider becomes the evidence, which is why every business in scope must be able to receive e-invoices. In the transition, where a buyer is not yet live, the Guidelines say the seller also gives a regular tax invoice, such as a PDF.

How long to keep them. E-invoices must be stored for the Tax Procedures law period. The Guidelines give 5 years after the tax period for taxable persons and 7 years for real estate records, with extensions during an audit or dispute. An older Ministry FAQ answer says 7 years for all. The sources differ; we follow the Guidelines.

What does not change for your VAT return

• Tax periods and returns. Articles 71 to 73 of the VAT law, on tax periods, returns and settlement, were not changed by the e-invoicing amendments. You still file a return for each tax period declaring all supplies made and received.
• The VAT treatment of each supply. E-invoicing does not change the VAT rate, place of supply or the reverse charge. Importing concerned goods and services under the reverse charge carries no e-invoicing requirement, and foreign suppliers' invoices do not go through the UAE network.
• Reporting is separate. Reporting e-invoice data to the FTA is done by your Accredited Service Provider, alongside your return, not in place of it.
• The pilot. During the Pilot Phase that started on 1 July 2026, exchanging e-invoices has no regulatory impact.

E-invoicing penalties apply only from the date you must implement. Businesses with revenue of AED 50,000,000 or more must appoint an Accredited Service Provider by 30 October 2026 (some older Ministry documents show an earlier date, which Ministerial Decision No. 66 of 2026 replaced). Smaller businesses must appoint one by 31 March 2027 and go live by 1 July 2027.

Frequently asked questions

Does e-invoicing change my VAT return?

No. The 2024 amendments that brought e-invoicing into the VAT law changed the definitions and Articles 55, 65, 70 and 76. The articles on tax periods, tax returns and settlement of tax were not changed by them. You still file your VAT return for each tax period as before.

Can I still recover input tax on a supplier's PDF invoice?

Not on its own, once your supplier must issue e-invoices. Article 55 of the VAT law, as amended, says that where a tax invoice must be, or has been, issued as an electronic invoice, you must retain it in line with the Electronic Invoicing System to recover the input tax. Keep the e-invoice you receive through your Accredited Service Provider.

Is the 14 day deadline for e-invoices new?

Not for VAT registered businesses. The VAT law already requires a tax invoice within 14 days of the date of supply, and the e-invoicing decision tells registrants to follow the VAT law timeline. A separate 14 day rule, counted from the date of the business transaction, covers everyone else in scope.
