Registration thresholds apply to resident businesses. Non-resident suppliers generally must register whatever their turnover when no one else in the country accounts for the VAT.

A 2026 amendment to the GCC VAT Agreement makes 5% a minimum rate and lets each state set its own. No state had announced a change by 30 October 2026.

Questions

What is the VAT rate in Oman?
5% on most goods and services, since VAT was introduced on 16 April 2021. Some supplies are zero-rated or exempt under the VAT law.
When does a business have to register for VAT in Oman?
When its taxable supplies over 12 months exceed OMR 38,500. It may register voluntarily from OMR 19,250. Non-resident suppliers generally register whatever their turnover when no one else accounts for the tax.
How do I remove 5% VAT from a price?
Divide by 1.05 to get the net amount, or by 21 to get the VAT. OMR 105.000 including VAT is OMR 100.000 net plus OMR 5.000 VAT.
Why are amounts shown to three decimals?
The Omani rial is divided into 1,000 baisa, so amounts are written to three decimal places and rounded to the baisa.
Is my data sent anywhere?
No. The calculation runs entirely in your browser and nothing is uploaded.
