Oman VAT calculator

VAT in Oman is charged on the supply and import of goods and services at 5% of the taxable value, unless the law sets an exemption or a zero rate.

Choose whether to add VAT to a price or take it out of a price that includes it, then enter the amount.

How it's calculated

Adding VAT: VAT = price × 5%, and the price with VAT = price + VAT.
Removing VAT: price before VAT = price with VAT ÷ (1 + 5%), and VAT is the difference.
Results are rounded to three decimal places.

An item priced at OMR 100 before VAT carries OMR 5 of VAT, for OMR 105 in total. If the price with VAT is OMR 105, the price before VAT is OMR 100.
