UAE VAT Invoice Requirements: What the FTA Expects (2026)

By Gulffigure · Updated November 2026 · 4 min read · Research-based

Key takeaways

Every tax invoice needs your TRN, a sequential number, and a line-by-line VAT breakdown.
Retail sales under AED 10,000 can use a simplified invoice.
Keep all invoices for 5 years — and never issue a VAT invoice without being registered.

Short answer: every tax invoice must show your TRN, a sequential invoice number, the date, supplier and customer details, a line-by-line VAT breakdown, and the total VAT in AED.

The FTA checklist

"Tax Invoice" clearly displayed
Supplier name, address and TRN (Tax Registration Number)
Customer name, address and TRN (if registered)
Sequential invoice number — no gaps, no duplicates
Date of issue and date of supply (if different)
Description of goods/services with quantities
Price per line excluding VAT, VAT rate and VAT amount per line
Total excluding VAT, total VAT, total including VAT — in AED (with exchange rate shown if billed in another currency)

Simplified invoices

For retail sales under AED 10,000 to unregistered customers, a simplified invoice is allowed: supplier details + TRN, description, total including VAT, and the VAT amount (or a statement that the price includes VAT). Your everyday shop receipt qualifies — check it shows the TRN.

Common mistakes that draw penalties

Missing or wrong TRN on the invoice
Non-sequential numbering (deleted or duplicated numbers)
VAT shown as a lump sum with no per-line breakdown
Issuing "VAT invoices" without being registered — an offence in itself
Not keeping invoices for 5 years

Annotated example: a compliant AED 10,500 invoice

Seeing the checklist applied to a real invoice makes it stick. Below is a sale of 10 office chairs at AED 1,000 each — AED 10,000 before VAT, AED 500 VAT at 5%, AED 10,500 total. Every row maps to a requirement from the FTA checklist above.

Invoice element	Compliant example
Document title	"Tax Invoice" printed at the top
Supplier block	Al Noor Office Supplies LLC, Dubai — TRN 100200300400003
Customer block	ABC Trading LLC, Sharjah — TRN 100200300400009 (included because the customer is registered)
Invoice number	INV-2026-0142 — follows INV-2026-0141, no gaps
Dates	Issue date: 3 Nov 2026 · Date of supply: 3 Nov 2026
Line 1	Office chairs × 10 @ AED 1,000 = AED 10,000 excl. VAT · VAT 5% = AED 500
Totals	Excl. VAT: AED 10,000 · Total VAT: AED 500 · Incl. VAT: AED 10,500
Currency	All amounts in AED (if billed in another currency, the exchange rate must appear)

Sanity-check the arithmetic before sending: 5% on AED 10,000 is exactly AED 500. Run your own figures through the VAT calculator — it takes seconds and catches the rounding errors auditors love to find.

B2B vs B2C: which invoice type to issue

The checklist above describes a full tax invoice. Not every sale needs one:

Business customer (registered): full tax invoice showing the customer's TRN — they need it to reclaim input VAT
Walk-in retail under AED 10,000: a simplified invoice is enough (supplier details + TRN, description, total including VAT)
Sale over AED 10,000 to an unregistered customer: issue the full tax invoice anyway, minus the customer TRN line
You are not registered: issue a normal commercial invoice with no VAT charged and no TRN — adding VAT without registration is an offence (see VAT penalties)

When in doubt, issue the fuller version: a simplified invoice where a full one was required is a defect; a full invoice where a simplified one would do is just extra diligence.

Cross-checking invoices before each VAT return

VAT returns are due within 28 days of each tax period, and the totals you declare must tie back to your invoices. Build a 10-minute pre-filing routine:

Tie the totals: sum the VAT on all invoices in the period — it must match the output VAT on your return to the fils
Check the sequence: scan invoice numbers for gaps or duplicates (a gap usually means a deleted or unrecorded invoice)
Verify TRNs: every purchase invoice you claim input VAT on must show the supplier's TRN — a missing TRN means no claim
Match zero-rated lines: supplies at 0% still appear on the return as zero-rated; make sure they aren't sitting in the exempt column (see zero-rated vs exempt)
File the period's invoices together: one folder per tax period makes the 5-year retention rule painless if you're ever audited

Get this routine wrong often enough and the FTA notices — and the bill for sloppiness is real. See what VAT penalties actually cost.
