VAT invoicing in Oman: a practical checklist
Oman charges VAT at 5%. This checklist covers what most businesses handle every week. It is general information, not tax advice: the Oman Tax Authority publishes the binding rules.
Before you issue invoices
Businesses whose taxable supplies pass the registration threshold must register for VAT, and others may register voluntarily. The Oman Tax Authority publishes the current threshold and how to register.
Rials, baisa and rounding
One Omani rial is 1,000 baisa, so amounts carry three decimals. Check that your software calculates VAT per line or per invoice in the way your accountant expects and shows three decimals everywhere, because a rounding gap of a baisa shows up in reconciliations.
What a tax invoice usually carries
Confirm the exact list with the Oman Tax Authority. In general:
- A clear tax invoice title and a unique, sequential invoice number.
- Date of issue.
- Supplier and customer names and addresses, and the supplier's VAT registration number.
- A description, quantity and unit price for each line.
- The VAT rate and amount in rials, plus the total.
Corrections and records
Correct a wrong or returned sale with a credit note that refers to the original invoice. Keep invoices, credit notes and supporting documents organised for the period the authority requires.
