Moving to Oman from the UK: The 2026 Tax Guide

Once you become non-resident under the UK Statutory Residence Test (SRT), the UK generally stops taxing your worldwide income and gains. Your Omani salary, foreign investment income and most overseas gains fall outside UK tax from the point you are treated as non-resident. That is what makes a move to a zero-income-tax country like Oman efficient: leave UK residence cleanly and the UK's taxing rights largely fall away.

The important exception is UK-source income and certain UK assets, which stay within UK tax even while you live in Oman. In practice that means:

• Rent from UK property remains taxable in the UK, usually under the Non-Resident Landlord Scheme. You still file a UK Self Assessment return for it.
• Gains on UK residential property are taxable under Non-Resident Capital Gains Tax (NRCGT), reportable within 60 days of completion (covered below).
• UK government and some occupational pensions can remain UK-taxable depending on the pension and the double taxation agreement. The UK and Oman do have a double taxation agreement in force, so pensions and other cross-border income may be relieved, but the outcome depends on the type of pension and needs checking case by case.
• Income from a UK trade or a UK company you continue to run may keep a UK footprint.

So the honest answer is: you stop paying UK tax on your worldwide income once you are non-resident, but you do not stop paying UK tax on income and gains that arise in the UK. The rest of this guide focuses on getting the residence position right and handling those UK-source items.

As at 2026, Oman levies no personal income tax on individuals. There is also no capital gains tax and no inheritance tax on individuals. That is the headline attraction for UK movers: employment income, investment income and gains on resale are not taxed at the personal level in Oman today. Oman does apply 5% VAT on most goods and services, and corporate income tax applies to businesses, but neither is a personal income tax.

The change to plan for is Oman's new Personal Income Tax Law. Oman issued Royal Decree No. 56/2025 on 22 June 2025 and published the law in the Official Gazette on 30 June 2025. It introduces a flat 5% tax and takes effect from 1 January 2028. For an individual who is tax resident in Oman, the 5% applies to worldwide income (income earned in Oman and abroad) above an annual threshold of OMR 42,000 (roughly USD 109,000); for non-residents, only Oman-source income is in scope. Income below the threshold stays exempt. This makes Oman the first Gulf Cooperation Council state to legislate a personal income tax.

The Oman Tax Authority has said the threshold is deliberately high and the rate deliberately low, so that around 99% of residents are expected to be unaffected. The law also contemplates deductions and reliefs for matters such as education, healthcare, primary housing, inheritance, zakat and donations. Detailed Executive Regulations, including how the tax base, deductions and filing will work in practice, are expected to be issued ahead of the 2028 start. The precise scope, the deductions, and how the OMR 42,000 threshold is measured for a given individual are to confirm until those regulations are published, so higher earners moving to Oman should keep this on their radar rather than treat Oman as permanently tax-free.

Your UK tax outcome depends on leaving UK residence, but to live in Oman you also need an Omani residence permit. The most common route is employment sponsorship: an Omani employer sponsors your residency, typically for a fixed renewable term. Business owners can use an investor route tied to establishing or investing in an Omani company.

For those relocating on capital rather than a job, Oman launched a Golden Residency programme on 31 August 2025. Reported thresholds are property investment of OMR 250,000 or more for a 5-year permit, and OMR 500,000 or more for a 10-year permit, with spouse and children includable and permits renewable while the conditions are met. Programme terms can be updated, and eligible asset types (for example freehold within designated developments, company shares or government bonds) and the exact minimums should be confirmed against current Invest Oman and Royal Oman Police guidance at the time you apply.

For tax purposes, the key figure is that Oman treats an individual as tax resident once their presence in Oman exceeds 183 days in a tax year, whether continuous or intermittent. That mirrors the day-counting logic you already know from the UK, and it matters for how the coming 2028 income tax will apply. Whichever visa route you use, make sure your actual days and your intentions line up with a genuine departure from the UK, because HMRC looks at substance, not just paperwork.

UK residence is decided by the Statutory Residence Test, not by where your visa is or where you feel you live. The SRT works through a sequence of tests based on days spent in the UK and your connecting ties. The day thresholds and ties are set in legislation and are unchanged for 2026/27.

The cleanest ways to be non-resident are the automatic overseas tests. Two are especially relevant to an Oman move:

• Fewer than 16 days in the UK in the tax year, if you were UK resident in any of the previous three tax years, makes you automatically non-resident (the limit is 46 days if you were not UK resident in any of those three years).
• Full-time work abroad: broadly, working sufficient hours overseas (averaging at least 35 hours a week) across the tax year with no significant break, while spending fewer than 91 days in the UK and no more than 30 of them working. This is the route many people use when they take an Omani job.

If neither automatic test is met, you fall into the sufficient ties test, where the number of UK days you can spend depends on how many ties (family, accommodation, work, 90-day and, for leavers, country ties) you keep. The more you keep in the UK, the fewer days you can spend before becoming resident again.

Because residence is assessed by whole tax year, the year you leave is handled by split-year treatment. If you qualify, the tax year is split into a UK part and an overseas part, so you are taxed as UK resident only up to your departure and as non-resident afterwards. The most relevant split-year case for an Oman move is usually the one for starting full-time work abroad, but there are several cases and each has strict conditions. Getting the departure date and the qualifying case right is what makes the difference between a clean break and an unexpected UK bill on post-departure income.

Leaving the UK does not sever UK tax on UK assets. If you keep a UK rental property, the rent stays UK-taxable. Under the Non-Resident Landlord Scheme, tax can be withheld at source unless HMRC approves you to receive rent gross, in which case you declare and pay through Self Assessment. As a British or UK national you keep your entitlement to the UK personal allowance (£12,570 for 2026/27), so much or all of modest rental profits may fall within it. Note that under the scheme basic-rate tax can still be withheld by your agent or tenant even where your income is within the allowance, so applying to receive rent gross is usually worthwhile.

When you sell UK residential property as a non-resident, Non-Resident Capital Gains Tax applies. You must report the disposal and pay any tax due within 60 days of completion, even if no tax is payable, using the standalone UK Property return. For 2026/27 the residential rates are 18% where gains fall within your unused basic rate band and 24% above that. For residential property held before April 2015, only the gain since April 2015 is typically chargeable, and you can use rebasing to the 5 April 2015 value or a straight-line time-apportionment basis, so the taxable gain is often smaller than the headline sale price suggests.

If you keep a UK company, the company remains UK tax resident and pays UK corporation tax on its profits as normal; your move does not change that. What changes is your personal position on dividends and salary: once you are non-resident, UK tax on your dividends is generally limited, but the interaction with disguised remuneration, close company rules and the temporary non-residence rules below means extraction should be planned around your departure and any planned return, not improvised. Where UK tax and Omani tax could both apply, the UK-Oman double taxation agreement is there to relieve double tax, but you should confirm the treaty treatment of each income type rather than assume it.

The single biggest mistake British movers make is assuming a short spell abroad wipes the slate clean. It does not. The temporary non-residence rules mean that if you leave the UK, become non-resident, and then return within roughly five years, certain income and gains you realised while abroad can be pulled back and taxed in the UK in the year you return.

The rules bite where you were UK resident in at least four of the seven tax years before you left, and your period of non-residence is five years or less. To be outside the rules, your non-residence must last more than five years (broadly five years and a day, measured on the SRT basis). Come back sooner and the anti-avoidance charge can apply.

What gets caught includes capital gains on assets you owned before leaving, certain distributions and share disposals, some pension lump sums and withdrawals, and other specific income. So if you plan to crystallise a large gain, take a pension lump sum, or extract profits from a UK company while enjoying Oman's zero-tax environment, the timing of any return to the UK is critical. Realising gains while non-resident is only genuinely UK-tax-free if you stay non-resident for the full period. Plan the exit and the potential return together, not as separate events.

Moving to Oman does not, on its own, mean you should move your UK pension out of the UK. Transferring a UK pension to a qualifying recognised overseas pension scheme (QROPS) can trigger the overseas transfer charge (OTC) of 25% of the transfer value. From 30 October 2024 the exclusion that had protected transfers to schemes in the EEA and Gibraltar was removed, so more transfers are now caught, and from 6 April 2025 an overseas scheme generally has to be in a country with a UK double taxation agreement and be appropriately regulated to qualify.

In practice there are effectively no QROPS in the Gulf, so a UK pension transfer into an Oman-based scheme is generally not an option, let alone an OTC-free one. For most people moving to Oman the sensible default is to leave UK pensions where they are and draw them under the UK rules and the UK-Oman treaty, rather than transfer. Any transfer should only follow specific regulated advice.
