If you are registered for VAT in the UAE, every taxable sale needs a proper tax invoice. A missing detail can cost your customer their input VAT claim and cost you a difficult conversation. Use this checklist to review your template.

Full tax invoice: required details

  • The words “Tax Invoice” clearly displayed.
  • Your name, address and Tax Registration Number (TRN).
  • The customer’s name and address, and their TRN if they are VAT-registered.
  • A unique, sequential invoice number.
  • The date of issue, and the date of supply if different.
  • A description of each item or service, with quantity and unit price.
  • Any discount shown.
  • The VAT rate applied (or zero-rated or exempt marking) and the VAT amount in AED.
  • The total payable in AED, with the gross amount before VAT shown. If the invoice is in another currency, the VAT amount must still be shown in AED.
  • A statement where the reverse charge mechanism applies.

Simplified tax invoice

For sales to customers who are not VAT-registered, where the total is small (typically up to AED 10,000), a simplified tax invoice may be used. It still needs your name, address and TRN, the date, a description of the goods or services, and the total amount and VAT charged. Retail and restaurant receipts commonly use this format.

Credit notes and debit notes

When you need to reduce or cancel a supply, issue a tax credit note that references the original invoice, shows the reason and the VAT adjustment, and carries its own sequential number. Never overwrite or delete an issued invoice.

Common mistakes

  1. Gaps or duplicates in numbering. Number automatically from one sequence per document type.
  2. VAT shown only as a percentage. The amount in AED must appear.
  3. TRN missing or mistyped. Store it once in your settings.
  4. Totals that do not add up. Round per line consistently and let software calculate.
  5. Using quotations as invoices. A quotation is not a tax invoice. Convert it when work is delivered.

A few practical tips

Issue invoices within 14 days of the supply or payment, whichever rule applies to your sale. Keep a PDF copy with the transaction. Add bank details and payment terms so customers pay faster. Offer bilingual English and Arabic layouts when your clients expect them. Our guide to bilingual business software explains how this works in practice.

Key takeaways

  • Show the words “Tax Invoice”, your TRN and a unique sequential number on every VAT invoice.
  • Show the VAT amount and the total payable in AED, even if you quote in another currency.
  • Use simplified tax invoices only for small sales to non-registered customers.
  • Correct mistakes with a credit note. Never edit or delete an issued invoice.
  • Keep a PDF of every invoice with its transaction for at least five years.
  • Let software do the numbering and arithmetic so people cannot get them wrong.
