Becoming non-UK resident does not end your relationship with HMRC. UK-source income remains taxable in the UK regardless of where you live — and the rules differ significantly by income type, by the double taxation treaty between the UK and your country of residence, and by your nationality.
This guide covers every major category of UK-source income, who is required to file a UK tax return from abroad, the personal allowance question, and the practical process of UK tax compliance as a non-resident.
The Statutory Residence Test: Establishing Non-Residency
Before addressing what is taxed, you must correctly establish that you are non-UK resident. Non-resident status is determined by the Statutory Residence Test (SRT), which was introduced in 2013 and replaced the previous case-by-case approach.
The SRT has three tiers:
Automatic overseas tests — if any apply, you are automatically non-UK resident:
- Fewer than 16 UK days in the tax year (if UK resident in any of the previous three years)
- Fewer than 46 UK days in the tax year (if not UK resident in any of the previous three years)
- Working full-time overseas (at least 35 hours per week, averaged over the year) with fewer than 91 UK days and fewer than 31 UK working days
Automatic UK tests — if any apply, you are automatically UK resident:
- 183+ UK days in the tax year
- Only home is in the UK (and you have lived there for 91+ days)
- Full-time working in the UK (35+ hours per week)
Sufficient ties test — if neither automatic test is conclusive, your residence depends on the combination of your UK days and your number of "ties" to the UK (UK family, UK accommodation, UK work, 90-day tie, country tie).
Getting this wrong has significant financial consequences. Non-residents who spend too many days in the UK or fail to meet the automatic overseas tests can be assessed as UK resident — meaning their worldwide income becomes UK-taxable. Take HMRC's guidance seriously and count your UK days carefully.
UK Rental Income: All Non-Residents Pay
This is the most straightforward area. If you own a UK residential or commercial property and it generates rental income, that income is taxable in the UK regardless of your residency status. There are no exceptions.
The Non-Resident Landlord (NRL) Scheme
Under the NRL scheme:
- If you rent through a letting agent, the agent withholds 20% basic rate tax from the rental income before paying it to you
- If you rent directly to a tenant, the tenant must withhold 20% basic rate tax from the rent (unless they pay less than £100/week and HMRC has not required them to withhold)
- You can apply to HMRC to receive rental income gross (without withholding) — this requires you to apply to the NRL scheme and demonstrate that your UK tax affairs are in order
Allowable deductions:
Allowable deductions against rental income for non-residents are the same as for residents:
- Mortgage interest — but subject to the Section 24 restriction (finance cost restriction). Individual landlords receive a 20% tax credit on mortgage interest rather than a full income tax deduction. This applies equally to non-resident individual landlords.
- Letting agent fees
- Repairs and maintenance
- Buildings and contents insurance
- Ground rent and service charges
- Property management costs
Net rental income is taxed at UK rates:
- 0% on income within the personal allowance (if you are entitled to it — see below)
- 20% basic rate on income up to £50,270
- 40% higher rate on income from £50,270 to £125,140
- 45% additional rate above £125,140
Self-assessment filing: Non-resident landlords with UK rental income must file a UK self-assessment tax return each year. Even if no tax is due (because income is within the personal allowance), you should register for self-assessment and file.
Employment Income for UK Work Days
Non-residents who perform some work duties in the UK — visiting their UK office, attending UK meetings, working on UK business while in the country — are taxable in the UK on the proportion of their employment income attributable to UK working days.
The apportionment:
Income is apportioned on the basis of UK work days versus total work days. If you work 250 days in the year and spend 30 days working in the UK, approximately 12% of your salary is treated as UK-source employment income and is taxable in the UK.
Double taxation treaty (DTT) implications:
Most bilateral DTTs include a provision that exempts short-term business visitor income from UK tax if:
- You are present in the UK for fewer than 183 days in a 12-month period
- Your remuneration is paid by (or on behalf of) an employer that is not UK resident
- Your remuneration is not borne by a UK permanent establishment of your employer
If all three conditions are met, the UK has no taxing right on the employment income from those UK working days under the treaty. However, the domestic UK legislation still applies — the treaty exemption must be actively claimed (by filing the return and claiming relief).
UK PAYE withholding:
UK employers operating PAYE must withhold tax on salary paid to non-UK residents if any UK duties are performed. They can apply to operate a modified PAYE arrangement (Section 690) if a proportion of duties are overseas.
Pension Income: Depends on the Double Taxation Treaty
This is the most treaty-dependent area. The UK has bilateral double taxation treaties with approximately 130 countries. The treatment of UK pension income under each treaty varies:
Common approaches:
UK has taxing right only: Some treaties give the UK exclusive taxing rights on UK pension income paid to a resident of the other country. In this case, the non-resident pays UK income tax at UK rates on the pension and pays no tax on it in their country of residence. Example: UAE (no income tax anyway, so this is academic).
Residence state has taxing right only: Some treaties give the country of residence exclusive taxing rights on UK pension income. In this case, the pension is taxable where you live and is not taxed in the UK. You must apply to HMRC for the pension to be paid gross (using the relevant double taxation treaty relief claim, typically the DT-Individual form or your country's equivalent). Example: varies by treaty.
Both states may tax: Some older or less specific treaties are ambiguous. Both countries may seek to tax pension income, with credit relief in one jurisdiction for tax paid in the other.
State Pension specifically:
Under most DTTs, the UK State Pension is either exempt from tax in the residence country (taxed only in UK) or taxed in the residence country. Where taxed in the UK, the rate depends on total UK income — the State Pension is simply added to other UK income sources.
Practical step: Identify the specific treaty between the UK and your country of residence and find the article dealing with pensions and government service pensions. HMRC publishes the full text of all UK double taxation conventions.
Savings Income: Usually Exempt From UK Withholding
UK bank interest received by non-residents is generally not subject to UK withholding tax under the UK's domestic rules. The UK does not tax interest paid to non-residents as a general rule (unlike some countries that impose withholding).
UK National Savings and other government savings products may have specific rules.
Under double taxation treaties:
Most UK treaties limit or eliminate UK withholding tax on interest. Where UK banks previously withheld tax on interest paid to non-residents, this has largely been removed.
However: Interest from UK sources is disclosed under CRS to your country of tax residence, where it is taxable according to local rules.
Dividends From UK Companies: No UK Withholding Tax
The UK does not apply withholding tax on dividends paid by UK companies to non-residents. This is unlike many continental European countries which withhold 15–25% of dividends at source.
A non-resident receiving dividends from UK companies pays no UK tax on those dividends.
However, the home country of residence will typically tax dividend income under local rules. The UK-source dividend is therefore taxable where you live, not in the UK (for non-residents). The CRS reporting ensures your home country tax authority is aware of the income.
The Personal Allowance: Does a Non-Resident Get One?
The UK personal allowance (£12,570 in 2026/27) is available to some non-residents and not others. The rules are complex but in summary:
Non-residents entitled to the full personal allowance:
- British nationals (all tiers, all residence positions)
- Nationals of EEA member states (their entitlement derives from UK domestic law and has been retained post-Brexit — check current HMRC guidance)
- Residents of countries with specific DTA provisions that preserve the personal allowance entitlement (some older treaty countries)
- Individuals who have been posted abroad by a Crown or government employer
- Certain retired Crown servants
Non-residents NOT entitled to the personal allowance:
- Non-EEA citizens resident in countries without treaty personal allowance provisions — unless they also hold British nationality
- If you are an Australian citizen, Canadian citizen, or US citizen who is not also a British national, you may not be entitled to the UK personal allowance
The practical importance:
If you are entitled to the personal allowance, your first £12,570 of UK income is tax-free. For a non-resident with UK rental income of £18,000, having the personal allowance means only £5,430 is taxable — a significant difference.
If you are not entitled to the personal allowance, all UK-source income is taxable from the first pound.
Claiming the personal allowance as a non-resident:
You claim the personal allowance on the UK self-assessment return. If you are a British national, you simply assert your entitlement on the form. If you are entitled under a treaty, the relevant box should be completed accordingly.
The Self-Assessment Filing Requirement
Non-residents must file a UK self-assessment return for a tax year if they have:
- UK rental income (regardless of amount)
- UK employment income above certain thresholds from UK work days
- UK pension income not already correctly taxed at source
- Capital gains from disposing of UK residential property (reported within 60 days of completion via the UK Property Reporting Service, in addition to the annual self-assessment return)
Registration: Register for self-assessment via HMRC's online service. You will need a Government Gateway account, which requires a UK National Insurance number and passport details.
Filing deadlines:
- Paper return: 31 October following the end of the tax year (5 April)
- Online return: 31 January following the end of the tax year
Payment deadlines:
- Balancing payment for the prior year: 31 January
- First payment on account for the current year: 31 January
- Second payment on account: 31 July
Payments on account apply where your previous year's self-assessment tax liability exceeds £1,000 and is not fully covered by PAYE deductions.
How to File From Abroad
Online: The HMRC self-assessment online service is accessible from abroad. You need a Government Gateway account. If you are filing for the first time, registering online from outside the UK can be cumbersome — HMRC's systems require identity verification that is easier if you have a UK phone number and UK bank account. Alternatively, you can register by post (form SA1).
By paper: Paper returns (SA100 with supplementary pages — SA105 for rental income, SA106 for foreign income, SA109 for residence claims) can be posted from abroad to HMRC.
Using a UK tax accountant: For anything beyond straightforward rental income, a UK-qualified accountant or tax adviser with experience of non-resident filings is strongly recommended. They understand the nuances of DTT claims, the NRL scheme, and the interaction of multiple income sources. The cost of a professional return is typically recoverable in avoided errors and optimised relief claims.
Common Errors Made by Non-Residents
Not filing at all: The most common error. Non-residents sometimes assume that leaving the UK ends all UK tax obligations. For those with UK rental income or pension income, this is not correct.
Missing the 60-day reporting deadline for CGT on UK property: UK residential property disposals by non-residents must be reported and tax paid within 60 days of completion, regardless of whether you file an annual self-assessment return. Missing this deadline results in automatic penalties.
Incorrect treaty claims: Claiming an exemption under a DTA without identifying the correct treaty article, or claiming a treaty country you are not actually resident in.
Failing to notify HMRC of overseas address: HMRC correspondence continues to go to UK addresses unless you update them. Missed correspondence leads to missed deadlines and, eventually, penalties.
