Leaving the UK does not end your relationship with UK income tax. If you still have UK income, such as a workplace or private pension, bank interest, dividends from UK shares or rent, UK income tax for expats abroad can still apply. Alongside any double tax agreement with the country you live in, two UK rules decide how much you actually pay. The first is whether you keep the UK personal allowance as a non-resident, which depends on your nationality and circumstances, not on where you live. The second is a less well known limit in the Income Tax Act 2007, often called the disregarded income rule, which can cap the UK tax on certain savings and investment income. This guide explains how both work in the 2026 to 2027 tax year, how they interact, how to claim, and why the country you now live in matters too. It is general information, not personal tax advice. Figures are for the 2026 to 2027 UK tax year and should be rechecked before you rely on them.
Once you are not UK resident under the Statutory Residence Test, UK tax can still apply to specified UK income and gains, including UK employment income for work done in the UK, UK rental income, UK pensions, UK savings and investment income, and gains on UK land and property. Being non-resident changes how that income is taxed, but it can remain within UK tax, subject to the statutory rules and any applicable double tax agreement. Whether a double tax agreement shifts the taxing right to your new country depends on the treaty and the type of income: many UK treaties give the country you live in the main or only right to tax private pensions, while government service pensions can stay taxable in the UK, but this depends on the treaty and the type of pension. The two rules in this guide, the personal allowance and the limit on liability for non-residents, sit underneath all of this and decide the UK tax on whatever the UK can still tax. If you are not sure whether you are non-resident yet, our guide to the Statutory Residence Test is the place to start. The limit on liability described below only applies where you are non-UK resident for the whole tax year. In a split year you are still UK resident for that tax year, with split-year treatment changing how income from the overseas part is taxed, so different rules apply.
The UK personal allowance is 12,570 pounds for 2026 to 2027, and the government announced at Budget 2025, in its policy paper on maintaining income tax thresholds, that it will stay at that level until 5 April 2031. Non-residents do not get it automatically. Under section 56 of the Income Tax Act 2007, a non-resident can claim it if, at any time in the tax year, they are a UK national or a national of an EEA state, are resident in the Isle of Man or the Channel Islands, previously lived in the UK and now live abroad for their own health or that of a family member living with them, are or have been employed in the service of the Crown, or are the widow, widower or surviving civil partner of someone employed in Crown service, among a few other narrow categories. Some double tax agreements also give residents of the other country a right to the allowance. So a British citizen living in Dubai generally keeps the allowance, while, for example, a non-EEA national who worked in the UK and has since moved to a country whose treaty does not include it may not. Where you are entitled to it, the allowance is reduced by 1 pound for every 2 pounds of adjusted net income above 100,000 pounds. Entitlement should be checked rather than assumed.
Section 811 of the Income Tax Act 2007 limits the UK income tax paid by an individual who is non-UK resident for the whole tax year, subject to some exceptions, for example where income is received through a UK representative. In broad terms, your liability cannot exceed the total of two amounts: any tax already deducted at source from your disregarded income, plus the tax you would pay on the rest of your UK income if the disregarded income were left out and the personal allowance were not given. Disregarded income is defined in section 813 and includes interest on UK bank and building society accounts and other interest from UK sources, dividends from UK resident companies, purchased life annuity payments, certain other savings and investment income, the UK State Pension and certain other UK social security pensions and benefits. Because UK banks and building societies have paid interest without deducting tax since April 2016, and UK companies do not generally deduct tax from ordinary dividends, the tax already deducted from this kind of income is often nil; that does not remove any reporting obligation. Older guidance may mention a notional tax credit that non-residents were treated as having paid on UK dividends: Finance Act 2026 repealed it (section 399 of the Income Tax (Trading and Other Income) Act 2005) for dividends received on or after 6 April 2026, so nothing is added back for UK dividends in the capped calculation from 2026 to 2027. Where the cap applies, it may reduce or eliminate UK tax on UK interest and dividends, but the personal allowance is lost against your other UK income, and the income is not necessarily tax-free overall.

This is where many people go wrong. The disregarded income definition does not cover most UK private pensions, workplace defined contribution pensions, drawdown income or defined benefit scheme pensions. The legislation only treats pension income from a registered pension scheme as disregarded in a narrow case linked to older retirement annuity contracts. UK rental income, UK employment income and UK trading income are not disregarded either. So the cap does not make a typical UK pension tax-free for a non-resident. Whether a UK pension is taxed in the UK at all is usually a question for the double tax agreement with your country of residence, and where a treaty gives the taxing right to your new country you may be able to apply for a no-tax (NT) code so the pension is paid without UK tax deducted. Our guide to drawing your UK pension while living abroad covers that process.
Where section 811 applies, the normal liability is compared with the capped liability and the lower one is charged, provided your income and residence position are correctly reported. The first calculation includes all of your UK income and gives you the personal allowance if you are entitled to it, together with any personal savings allowance, starting rate for savings and dividend allowance available under the normal rules. The second leaves out your disregarded income and the personal allowance, then adds back any tax already deducted from the disregarded income; double taxation relief is also left out of this capped calculation. HMRC's PAYE Manual (PAYE13144) states that for Self Assessment cases its system runs the two calculations and applies the more beneficial one, and describes the same comparison for PAYE cases. As a rule of thumb, the cap tends to help where your disregarded income, such as interest and dividends, is large compared with the personal allowance, and tends not to help where most of your UK income is a taxable pension or rent and your savings income is modest. For 2026 to 2027, dividends above the 500 pound dividend allowance are taxed at 10.75% in the basic rate band and 35.75% in the higher rate band, up from 8.75% and 33.75%, with the additional rate unchanged at 39.35%, which can make the comparison more significant for investors with UK shares held directly. The basic rate band is 37,700 pounds above the personal allowance. From 6 April 2027, the government has announced that the basic, higher and additional rates on savings income will rise by 2 percentage points, to 22%, 42% and 47%. These 2027 to 2028 savings rates were announced at Budget 2025 and should be rechecked before that tax year begins, and the comparison rerun each year.
If you complete a UK Self Assessment return, you claim the personal allowance and the residence position on the residence pages of the return, and you do not need a separate form. HMRC's R43 guidance says you must use Self Assessment instead if, for example, you have UK rental income over 2,500 pounds or income from a trade, vocation or profession. Otherwise, HMRC's form R43, which can be completed online or on paper, lets a non-resident claim the personal allowance and a repayment of overpaid UK tax for the current tax year and the previous four tax years. Check the current R43 guidance notes for the year you are claiming, as the detailed conditions can change. The UK result is only half the picture. Many countries tax their residents on worldwide income, including UK interest, dividends and pensions, with credit for any UK tax under the relevant treaty: Spain and Portugal, for example, generally tax residents on worldwide income, subject to special regimes and treaty rules, so UK savings income that bears no UK tax may still be taxed locally. The UAE is a good example of why the treaty can matter more than either UK rule. Under the 2016 UK to UAE double taxation convention, private pensions paid to a UAE resident are generally taxable only in the UAE (Article 17, with government service pensions dealt with separately), interest beneficially owned by a UAE resident individual is generally taxable only in the UAE, because individuals are one of the qualifying categories in Article 11, and UK dividends beneficially owned by a UAE resident are generally exempt from UK tax (Article 10, except certain dividends from property investment vehicles), all subject to the treaty's residence, beneficial ownership and anti-abuse conditions. Treaty relief generally has to be claimed, and UK rental income remains taxable in the UK. The UAE does not currently levy personal income tax on individuals' ordinary pension, savings and investment income, though UAE corporate tax can apply to business activity, so a genuine UAE resident's position should be confirmed rather than assumed. In every case, a lower UK calculation does not mean that a pension, investment or withdrawal is tax-free. The right answer depends on both systems together, which is why it is worth reviewing your position with a regulated financial adviser before you restructure savings or investments. If you are planning to come back, our guide to returning to the UK explains how some income and gains realised abroad can be caught on return.
Most people I speak to have heard of the personal allowance but not of the limit on liability, and the two pull in opposite directions. The cap can reduce or remove UK tax on UK interest and dividends, but it costs you the allowance on everything else, it does nothing for a typical private pension, and it does not make the income tax-free overall. For some countries the treaty matters more than either rule. The most reliable way to know which outcome applies is to run both calculations with your actual figures, and then check what your country of residence does with the same income.

Many British citizens abroad assume that becoming non-resident means losing the personal allowance, which may result in more UK tax being deducted than necessary. UK nationals and EEA nationals generally keep the right to claim it, as do several other groups, so tax deducted from UK pensions or employment income may be partly reclaimable.
The reverse mistake catches non-EEA nationals who lived and worked in the UK. Entitlement depends on nationality, Crown service, health-related moves and the relevant treaty, not on having once been UK resident, so it should be checked before you plan around it.
The disregarded income rule covers the UK State Pension and certain other social security income, but not most private, workplace or drawdown pensions. Relying on the cap to shelter a UK pension may lead to an incomplete assessment of the position. The treaty position and an NT code are usually the relevant questions.
The limit on liability is not a free extra. It works by ignoring the disregarded income and the personal allowance together, so for someone with a sizeable taxable pension and only modest savings income the normal calculation is usually better. HMRC applies whichever is lower, but only if your return or claim is complete.
The personal allowance and the cap are UK domestic rules, but a treaty can take UK income out of UK tax altogether. Under the UK to UAE treaty, for example, private pensions, interest and dividends paid to a UAE resident are generally not taxed in the UK, subject to conditions, but the relief usually has to be claimed. Comparing only the two UK calculations can miss a better result.
UK interest and dividends that bear little or no UK tax are not necessarily tax-free. Residents of Spain, Portugal and many other countries are generally taxed on worldwide income, so the saving in the UK can be offset by local tax. Check both sides before moving money or investments.
Where expats hold their savings and investments has a real effect on their tax, in the UK and where they now live. Moving money around purely to chase a UK saving can backfire if the new country taxes it instead, so it is worth looking at the structure as a whole before making changes.
Illustrative example only, not a real client. This example is simplified, uses 2026 to 2027 UK rates and allowances, and is not a guarantee of any outcome. It assumes Mark lives in a country with no double tax agreement with the UK, so no treaty relief applies; tax in his country of residence is outside the scope of the example. For a UAE resident, for instance, the UK to UAE treaty could change the UK result substantially. Mark has been non-resident for several full tax years and has three sources of UK income: 20,000 pounds a year of taxable drawdown income from a UK personal pension, 15,000 pounds of interest from UK savings accounts and 10,000 pounds of dividends from UK shares held directly. He assumed that, as a non-resident, he had no personal allowance and that all of his UK income was taxable in full.
A review checked his entitlement first: as a British citizen he could claim the personal allowance. It then compared the two UK calculations. With the personal allowance and all income included, his estimated UK liability was about 5,307 pounds: 7,430 pounds of pension above the personal allowance at 20%, 14,000 pounds of interest at 20% after the 1,000 pound personal savings allowance (the starting rate for savings was not available because his pension exceeded the personal allowance by more than 5,000 pounds), and 9,500 pounds of dividends at 10.75% after the 500 pound dividend allowance. Leaving out the disregarded interest and dividends, and the personal allowance with them, the tax on the pension alone at the basic rate was about 4,000 pounds, with no tax deducted from the interest or dividends to add back. The capped calculation was therefore the lower one. The review also flagged that tax in his country of residence needed checking separately, and that the comparison would need rerunning when UK savings rates rise from April 2027.
The outcome is specific to these assumed figures; it is not a tax calculation, forecast or recommendation, HMRC's actual calculation may differ, and it does not indicate the result for any other individual. Mark understood that the pension, not his savings, was the main driver of his UK bill, and that how his savings and investments were held, and in which country, mattered more than he had realised. He then took the compliance steps with a qualified tax specialist. A review like this establishes the facts; it does not file returns or guarantee a refund.

Possibly. Under section 56 of the Income Tax Act 2007, non-residents can claim it if they are UK or EEA nationals, are resident in the Isle of Man or Channel Islands, moved abroad for health reasons, or have worked for the Crown, among a few other categories. Some double tax agreements also give an entitlement. For 2026 to 2027 the allowance is 12,570 pounds.
It is UK income defined in section 813 of the Income Tax Act 2007, including UK interest, dividends from UK companies, purchased life annuities, the UK State Pension and certain other social security income. Under section 811, a non-resident's UK tax can be limited to the tax already deducted from this income plus the tax on their other UK income calculated without the personal allowance.
Generally not. Most private, workplace and drawdown pensions are outside the definition, apart from a narrow case linked to older retirement annuity contracts. Whether a UK pension is taxed in the UK is usually decided by the double tax agreement with your country of residence, and you may be able to apply for an NT code where the treaty gives the taxing right to that country.
You do not usually have to choose yourself. HMRC guidance states that for Self Assessment cases its system calculates the liability both ways and applies the more beneficial result, and describes the same comparison for PAYE cases. Your return or claim needs to show your residence position and income correctly for this to work.
Often not, if you are genuinely UAE resident and claim treaty relief. Under the 2016 UK to UAE double taxation convention, private pensions paid to a UAE resident are generally taxable only in the UAE, interest beneficially owned by a UAE resident individual is generally taxable only in the UAE, and UK dividends are generally exempt from UK tax, subject to the treaty's conditions. Government service pensions and UK rental income are treated differently, so check your own position.
If you file a UK Self Assessment return, you claim it on the residence pages of the return. If you do not, form R43 lets you claim the allowance and any repayment of UK tax for the current tax year and the previous four tax years, online or by post. HMRC's guidance says you must use Self Assessment instead if, for example, you have UK rental income over 2,500 pounds.
