How vat / sales tax works in Oman
Oman VAT defaults to 5% on domestic supplies, with businesses charging output tax, deducting input tax, and filing quarterly returns through the Tax Authority portal.
Registration is mandatory past OMR 38,500 of taxable supplies with voluntary entry from OMR 19,250, while exports, international transport, and defined essentials zero-rate.
Financial, health, education, and real-estate supplies are largely exempt, and GCC intra-regional flows follow destination mechanics.

Watch out for
- Low thresholds catch small traders early: OMR 38,500 mandatory and OMR 19,250 voluntary lines sit far below Gulf neighbours' levels.
- Exempt finance, health, and property supplies block input recovery, repricing mixed contracting against taxable competitors.
- The 2028 personal income tax adds a parallel track for high earners, which changes total-burden modelling on identical activity.
- Excise taxes on tobacco, alcohol, pork, and sugary drinks stack beside VAT on defined goods.
