A tax invoice is a VAT document that must contain the information required by UAE VAT law. An e-invoice is the same document issued as structured data that passes through an Accredited Service Provider and is validated and reported. The VAT content rules continue to apply. What changes is the format, the route and the checking.
The core difference
| Feature | Tax invoice today | E-invoice under the new system |
|---|---|---|
| Format | Paper, PDF or other agreed format | Structured data (PINT AE) in a set format |
| How it is sent | Email, post or portal | Through an Accredited Service Provider over the network |
| Checking | By the buyer, later by an auditor or the FTA | Validated before sending |
| Reporting to the FTA | Through the VAT return | Invoice data also sent to the authority |
| Corrections | Credit note on paper or PDF | Credit note as structured data referring to the original |
What stays the same
The VAT law's requirements for what a tax invoice must show, such as the supplier and customer details, the date, a description, the tax rate and amount and the total, continue to apply. The rules on when to issue an invoice, how to treat zero-rated and exempt supplies and when output tax is due are not replaced by e-invoicing. See tax invoice requirements. The VAT return still has to be filed; see VAT return due dates.
What changes for finance teams
- Invoices are created in a system that can produce structured data, not in a word processor.
- Customer tax numbers and identifiers must be correct before the invoice is raised.
- Invoice status is tracked: sent, accepted, rejected.
- Corrections must follow the structured credit note process.
- Your own copy and the one the customer receives are linked by the network.
What happens to PDFs
Commentary says a PDF copy may still be sent or kept for people, but the structured data is the official invoice in scope of the mandate. Do not assume a PDF alone satisfies the rule once your phase is live. Check the Ministerial Decision for the treatment of copies and for what you must retain. See tax record retention.
Which transactions are covered
The current phases are described as covering business-to-business and business-to-government transactions. Consumer sales may be handled differently, and secondary sources do not fully agree on how. Confirm your own scenarios against the Ministry's guidance, particularly if you run retail or online sales; see VAT on e-commerce.
First steps
- List the document types you issue: invoices, credit notes, debit notes, advance receipts.
- Check each against the data dictionary; see mandatory fields.
- Pick an ASP; see how to choose.
- Update your invoice procedure and train your team.
Examples
A trader sells goods to a UAE customer on 5 December. Today the trader emails a PDF with the tax invoice details and posts the sale in the ledger. Under the new system, the billing system creates the structured data on 5 December, the provider validates it, sends it to the customer's provider and reports the tax data. If the customer's tax number is wrong, the provider rejects the invoice before the customer ever sees it, and the trader must fix and resend. In the old process, the error might have surfaced weeks later in the customer's input VAT claim. The same VAT is due in both cases; the difference is that the error is caught at the start.
Credit notes and corrections
Under current VAT practice, a credit note corrects an invoice that was wrong or where the price changed. In the e-invoicing system, the credit note is also a structured document that refers to the original invoice number. If the original invoice never went through the network, because it pre-dated your go-live date, check with your provider how to reference it. Keep a clear policy on who may issue credit notes and how they are approved. See VAT credit and debit notes.
Timing of issue
The VAT rules on when an invoice must be issued continue to apply. The e-invoicing rules add the requirement that the invoice must be transmitted through the network within the time the decision sets. Check the decision for any maximum time between supply and transmission, and design your billing process to meet it. Do not issue invoices in batches at the end of the month if the rule requires faster issue.
Records and audit trail
The structured invoice, its status messages and any readable copy form part of your records. During an FTA review, you may be asked to show that an invoice was sent, accepted and matches your return. Keep the data for the retention period and make sure you can retrieve it quickly. See tax record retention.
