Oman Invoice Maker — VAT Invoices in Omani Rial

Oman introduced 5% VAT in April 2021 and moves to Fawtara e-invoicing in 2027. Until your business is in scope, a well-formed PDF tax invoice is what Omani buyers and the Oman Tax Authority expect: your VATIN, the buyer's VATIN for business sales, VAT shown per line and every amount in Omani Rial to three decimals.

A PDF invoice from DocMak can be used until e-invoicing becomes mandatory for your business on the dates above; after that, the tax invoice goes through an accredited provider.

What an Omani tax invoice must show

A VAT-registered supplier in Oman issues a tax invoice for taxable sales. Check that yours carries:

  • The words “Tax Invoice” and a unique sequential number
  • Issue date and, where different, the supply date
  • Your name, address and VATIN
  • The buyer's name, address and VATIN for business customers
  • Description, quantity and price excluding VAT for each line
  • VAT rate and VAT amount, and the total including VAT in OMR

Getting ready for Fawtara

Fawtara starts with a voluntary pilot in late August 2026. It becomes mandatory on 1 April 2027 for businesses with annual supplies above OMR 5 million and on 1 October 2027 for everyone else registered for VAT. From your date, invoices go through an accredited e-invoicing provider. Keep clean numbering, customer VATINs and line data now and the switch is far easier.

Baisa, rounding and VAT

Calculate VAT on each line and round to the baisa, then add the lines; rounding only the grand total often leaves a one-baisa difference against the buyer's system. DocMak works in three decimals throughout so the VAT total equals the sum of the lines.
