Oman VAT calculator — 5%, to the baisa

Calculate Omani VAT at the 5% basic rate, adding it or extracting it, in Omani rials. Results carry three decimals — baisa — because the rial is a thousand-baisa currency.

In OMR. Arabic (١٢٣) and Latin (123) numerals both work.

Enter an amount to see the result.

The Omani rial is a three-decimal currency: its minor unit is the baisa, one thousandth. That is why the result carries three decimals rather than two.

This calculator performs a purely mathematical VAT calculation using the rate you select. VAT treatment varies by transaction, goods or services, customer and applicable rules — supplies may be standard-rated, zero-rated, exempt or out of scope. Verify the rate and the treatment for your transaction with the relevant tax authority or a qualified tax professional.

Oman’s basic VAT rate

The Oman Tax Authority states a basic rate of 5% applied on most goods and services. Alongside it are zero-rated supplies — exports, international transport and a list of essential goods — and exempt activities including financial services and the rental of residential property.

The Omani rial: 1,000 baisa, three decimals

The Omani rial divides into 1,000 baisa, not 100, so its amounts are written to three decimal places. Most online calculators render Omani results to two decimals and lose the baisa.

Example: OMR 10.500 including 5% VAT contains 0.500 of VAT, leaving 10.000 before VAT. The three figures reconcile exactly.

Adding and removing 5%

Adding: total = amount × 1.05. OMR 2,000.000 before VAT gives 100.000 of VAT and a total of 2,100.000.

Removing: amount before VAT = total ÷ 1.05, and the VAT is the difference. Do not take 5% off the inclusive figure — that gives the wrong answer.

Why the tool will not decide taxability for you

The Oman Tax Authority publishes separate sector guides for imports and exports, financial services, healthcare, education, real estate, special zones, electronic commerce and capital assets. When the authority itself needs that many guides to answer "is this transaction taxable", a calculator has no business claiming to answer it automatically.

This tool applies the rate you choose to the amount you enter, exactly. Choosing the right rate is a matter for the Tax Authority or a tax professional.

The calculator for each country

Each country has its own page, because the rate, the currency and the number of decimal places differ: the Bahraini dinar and the Omani rial carry three decimals, not two.

Frequently asked questions

What is the VAT rate in Oman?

The basic rate is 5% on most goods and services, with zero-rated supplies and exempt activities alongside it.

How do I calculate VAT in Oman?

To add, multiply the amount by 1.05. To extract from an inclusive total, divide by 1.05 and subtract the result from the total to get the VAT.

Why does the result show three decimal places?

Because the Omani rial divides into 1,000 baisa. Rounding to two decimals drops the baisa and leaves figures that will not match accounting records.
