Income tax in Oman (2026): what you keep and what changes in 2028

Oman charges no personal income tax on employment income in 2026, so an expat on OMR 18,000 a year keeps the full OMR 18,000. An Omani national pays 8% into the Social Protection Fund, OMR 1,440 on the same pay, and keeps OMR 16,560. A personal income tax of 5% on income above OMR 42,000 a year is planned to start on 1 January 2028.

What the law says

The figures are the 2026 rules as the calculator models them. Oman is changing: it is the one Gulf state here with a personal income tax on the way. Until then, the only deduction from pay is social insurance for nationals.

No personal income tax in 2026, a new tax from 2028

Oman does not tax salary in 2026. The calculator records a personal income tax of 5% on income above OMR 42,000 a year starting 1 January 2028, so it would affect only high earners. Check the final rules before relying on this, since details can change. VAT, where a country charges it, is a consumption tax added to what you buy and is not taken from your pay, so it is not part of this calculation.

Social Protection Fund for Omani nationals

Omani nationals pay 8% of pay to the Social Protection Fund, on pay up to OMR 3,000 a month. The employer pays its own share on top, which is not shown and does not reduce your pay.

Who	Employee rate	Monthly pay cap
Omani national	8%	OMR 3,000
Expat	None	Not applicable

Expats: no social insurance

Expatriates pay nothing into the Social Protection Fund. The employer owes an end-of-service gratuity under the labour law when the contract ends. It is not part of the figures.

Rules for 2026. Every amount below is worked out by the calculator's own engine, the same one the tool runs.

Take-home pay for an expat in Oman on OMR 18,000

An expat on OMR 18,000 pays no income tax and no social insurance in 2026, so take-home pay is OMR 18,000, or 100% of gross. The planned 5% tax from 2028 applies only above OMR 42,000 a year, so this salary would not be affected.

How much do Omani nationals pay to the Social Protection Fund on OMR 18,000?

An Omani national on OMR 18,000 pays no income tax but 8% to the Social Protection Fund, OMR 1,440 a year. You keep OMR 16,560, or 92.0% of gross. Pay is OMR 1,500 a month, below the OMR 3,000 monthly cap, so the full 8% applies.

The contribution builds social protection rights. From 2028 the planned 5% tax would add to it only on income above OMR 42,000 a year.

How to pay less tax, legally

These are mainstream, legal ways to handle your pay and tax position.

Check your home-country tax residency before you move

Suits: every expat. Zero tax in the Gulf does not always mean zero tax overall: some countries tax citizens on worldwide income, and others treat you as resident until you meet their exit conditions.

Caveat: the rules sit in your home country's law, not in the Gulf state's. Ask your home tax authority or an adviser, and keep records of your move.

Save and invest the extra take-home yourself

Suits: expats who keep the whole salary. Without a pension deduction, retirement saving is your own job. Regular contributions to a pension or investment plan in your home country or a low-cost portfolio are the usual route.

Caveat: a gratuity at the end of the contract is not a retirement plan, and where you invest decides the tax on the returns. Use the Financial Freedom Calculator to see how much you need.

Watch the 2028 income tax if you earn above OMR 42,000

Suits: high earners planning a move for 2028 or later. The planned 5% applies above OMR 42,000 a year.

Caveat: final rules, definitions of income and exemptions may differ from the plan, so check the official guidance as it is published.

What the calculator does not model

Employment income only. It models one salary for a full year, with no other income, bonuses or a part year.
Gratuity not modelled. End-of-service gratuity depends on your basic pay, length of service and contract, so it is not added to the figures.
Home-country tax. The calculator shows only what the Gulf state takes. Your home country may still tax you on worldwide income, depending on its rules and any treaty.
You choose the status. The calculator takes national or expat from you and does not test whether you qualify.
Package versus cash. The calculator takes the gross pay you enter. Housing, schooling or flight allowances in your contract are not split out.
The 2028 tax is not applied. The calculator shows it only as a note, with a zero amount, because it starts after 2026.

General information, not tax advice. The figures follow the rules as published for the year shown. Check the ones that matter to you with the tax authority or an adviser before you sign a contract.

Frequently asked questions

How much tax do I pay on OMR 18,000 in Oman?

An expat pays no income tax and keeps OMR 18,000. An Omani national pays 8% to the Social Protection Fund and keeps OMR 16,560. Try your own figure in the Global Income Tax Calculator.

Is Oman introducing an income tax?

As the calculator models it, yes: a personal income tax of 5% on income above OMR 42,000 a year is planned from 1 January 2028. In 2026 there is none. It would reach only high earners, and the final rules should be checked when published. The calculator shows it as a note with zero amount.

What is end-of-service gratuity in Oman and does it replace a pension?

For expats, in practice yes. They are outside the Social Protection Fund, so the employer pays a gratuity at the end of the contract under the labour law, based on pay and years of service. It is paid once. The calculator leaves it out because it depends on your contract.

Why do Omanis pay 8% and expats nothing?

The Social Protection Fund covers nationals. The employee pays 8% of pay up to OMR 3,000 a month, and the employer pays a share on top. Expats are not covered, so no deduction applies.

Do I need to pay tax at home if I work in Oman?

It depends on your home country, which the calculator does not model. Some countries tax citizens on worldwide income or keep you resident for tax for a time. Check with your home tax authority.
