How the calculation works
Adding VAT multiplies the net price by (1 + rate). Removing VAT divides the gross price by (1 + rate). Subtracting the rate from the gross price gives the wrong answer: 19% of 119 is 22.61, but the VAT included in 119 at 19% is 19.00. Amounts are rounded to two decimals at the end.
Frequently asked questions
What is the VAT rate in Oman?
The standard VAT rate in Oman is 5%. There is no reduced rate: almost everything taxable is charged at the standard rate.
How do I add VAT to a net price?
Multiply the net price by 1.05 (1 plus the 5% standard rate). For example, OMR 100.000 × 1.05 = OMR 105.000, of which OMR 5.000 is VAT.
How do I work out the VAT included in a gross price?
Divide the gross price by 1.05. For example, OMR 105.000 ÷ 1.05 = OMR 100.000 net, so the VAT included is OMR 5.000. Taking 5% of the gross price would overstate the tax.
When does a business have to register for VAT in Oman?
Mandatory registration at OMR 38,500 annual supplies (actual or expected); voluntary from OMR 19,250
