How it works
Articles 55 and 56 of Oman's VAT Law require a business to register when the value of its taxable supplies over the previous twelve months, or the expected value over the next twelve, exceeds the mandatory threshold the Tax Authority's Chairman set at OMR 38,500; sales of capital assets are left out. Article 61 allows voluntary registration when supplies or taxable expenses exceed OMR 19,250. Both tests say 'exceeds', so a business at exactly the threshold is not yet obliged or entitled. The Executive Regulation gives thirty days to apply and makes registration effective from the first day of the following month. The checker applies these tests to the figures you enter, gives the result, and when registration is required shows the application deadline counted from the end of the month entered.
What is checked
- Must register: past or next 12 months > OMR 38,500
- May register: supplies or expenses > OMR 19,250

Questions
What is the VAT registration threshold in Oman?
Mandatory when taxable supplies over the past or next 12 months exceed OMR 38,500; voluntary when supplies or expenses exceed OMR 19,250.
How long do I have to register in Oman?
30 days; registration takes effect on the first day of the following month (Executive Regulation Articles 110 and 115).
Does exactly OMR 38,500 require registration?
No. The law says 'exceeds', so registration becomes mandatory only above OMR 38,500.
Do capital asset sales count towards Oman's threshold?
No. Sales of capital assets are left out of the rolling twelve-month total used for the OMR 38,500 test.
When does e-invoicing start in Oman?
The Tax Authority has announced e-invoicing phases from 2027 (decision 189/2026); registration thresholds are unchanged by it.
