How to Claim Back UK Tax as a Non-Resident

The UK withholds tax at source from a range of income types — pension payments, rental income from UK property, and historically various forms of investment income. As a non-resident, you may have the right under a double tax treaty (DTT) to receive some or all of this income without UK tax deduction, or at a reduced rate. But the exemption is not automatic — you need to apply for it.

This guide covers the main reclaim routes and how to navigate HMRC's processes as a non-resident.

UK pension income: the NT tax code

When a UK pension (personal pension, occupational pension, SIPP) pays out to a non-resident, UK PAYE income tax is deducted at source — typically at the basic rate (20%) by default — unless you have obtained an NT code (No Tax) or a reduced-rate code from HMRC.

The basis for claiming relief is almost always the double tax treaty between the UK and your country of residence. Most UK DTTs provide that UK pension income is taxable only in the country of residence (not the UK), meaning the UK should not deduct any tax at all. The specific terms vary treaty by treaty — some treaties reserve the right to UK taxation on state pensions or certain government pension types.

How to apply:

1. Obtain form DT-Individual from HMRC (available on HMRC's website). This is the standard form for claiming treaty relief on UK income as a non-resident.
2. Complete the form, including your country of residence and the relevant treaty provision.
3. Have the form certified by the tax authority of your country of residence (they stamp and sign it to confirm you are a resident taxpayer there).
4. Submit the completed, certified form to HMRC.
5. HMRC will issue an NT code (or reduced withholding code) directly to your pension provider.

Processing time varies — allow 3–6 months. During this period, you may continue to have tax deducted; you can reclaim it via self-assessment once the NT code is in place.

If you have already had tax deducted, you can reclaim it by filing a UK self-assessment tax return as a non-resident, or by using form R43 (claim by non-residents to UK income tax repayment).

UK rental income: the Non-Resident Landlord scheme

If you own UK property and rent it out while living abroad, the default position is that your tenant (or the letting agent) must deduct basic-rate income tax from the rental payments and pay it to HMRC. This is the Non-Resident Landlord (NRL) scheme.

You can apply to have rental income paid to you gross — without tax deducted at source — by completing form NRL1 (for individuals) and submitting it to HMRC. HMRC will then notify your letting agent or tenant to pay rent without deduction, subject to you undertaking to complete an annual UK tax return.

Registering under the NRL scheme does not make the rental income tax-free — you still owe UK tax on it (UK property income is subject to UK tax regardless of your residence status). But it removes the withholding and allows you to pay the tax through self-assessment in the normal way, potentially after deducting allowable expenses.

If you have a letting agent, the agent deducts tax by default until HMRC issues approval for gross payment.

Dividends from UK companies

UK dividends are generally paid without withholding tax under domestic UK law (the UK does not impose a separate dividend withholding tax on most share distributions). If you receive dividends from UK-listed shares, they will typically arrive gross.

However, where you receive income through certain intermediary structures, or where older arrangements exist, a withholding may apply. Treaty relief can be claimed via DT-Individual if relevant.

Note: UK dividends received by non-residents may be taxable in the country of residence — check local rules.

UK savings interest

UK banks historically operated the R85 form system, whereby non-taxpayers could register to receive interest gross. The introduction of the Personal Savings Allowance largely changed this for basic-rate taxpayers, and most bank interest is now paid gross by UK institutions.

However, if a bank has withheld tax from interest (which can happen in some circumstances), you can reclaim it via self-assessment or form R43.

UK self-assessment for non-residents

Many non-residents with UK income sources need to file a UK self-assessment tax return (form SA100 with the non-resident supplementary pages SA109).

You may need to file self-assessment if you have:

• UK rental income
• UK employment income (if you continued to have UK employment while partly non-resident)
• UK pension income above the personal allowance
• UK capital gains on UK property (a separate UK property disposal return is required within 60 days of completion)

Non-residents may be entitled to the UK personal allowance (£12,570 as of 2026) — either under a treaty provision, or as a UK national, or as a resident of certain EEA countries under older rules. Check the current position with an adviser, as entitlement varies.

HMRC helpsheet HS304 (Non-residents and income tax) provides detailed guidance on which income types are subject to UK tax as a non-resident and how to calculate the liability.

Practical tips

• Act early on NT codes. Processing times are long, and reclaiming tax already withheld via self-assessment is more burdensome than having the correct code in place from the start.
• Keep your UK self-assessment registration active if you have ongoing UK income — even small income sources can require annual returns.
• Retain copies of all HMRC correspondence — particularly approval letters for NT codes and NRL scheme registration, as pension providers and letting agents periodically ask for re-confirmation.
• Check each treaty individually. No two double tax treaties are identical. The UK–Cyprus treaty, UK–UAE treaty (limited in scope — no UAE income tax to relieve), UK–Spain treaty, and UK–Thailand treaty all have different provisions for pensions, interest, and dividends.
• Use a UK-qualified tax adviser. For non-residents with multiple UK income sources, an adviser with experience of non-resident UK tax returns can save more than their fee through correct treaty claims and allowable expense deductions.

Capital gains on UK residential property: the 60-day rule

A separate UK reporting obligation applies to non-residents who sell UK residential property. This is not a reclaim route — it is an obligation — but it intersects with the broader framework of non-resident UK tax compliance.

Since April 2015, non-residents have been subject to Non-Resident Capital Gains Tax (NRCGT) on UK residential property disposals. Since April 2019, this was extended to cover UK commercial property and UK-holding entities as well. A return must be filed with HMRC — and any tax due paid — within 60 days of completion. This is a tight deadline that catches many sellers off guard, particularly those managing the sale from overseas.

The gain is calculated from the April 2015 base (for residential property) using a rebasing method: you can opt to use the market value at April 2015 as the base cost rather than the original purchase price. This can significantly reduce the taxable gain for properties held before 2015.

If you are UK tax resident in the year of disposal (even temporarily, or by spending too many days in the UK that year), different rules may apply. Always check your residency status against the Statutory Residence Test before assuming NRCGT treatment.

Interaction of UK tax with the non-resident landlord scheme: expenses

One frequently overlooked benefit of the Non-Resident Landlord scheme is that once registered, your letting agent or the tenant pays rent gross to you, and you account for the tax through UK self-assessment — which means you can deduct allowable expenses in calculating the net rental profit.

Allowable expenses include:

• Letting agent fees (typically 10–15% of gross rent)
• Repairs and maintenance (not improvements)
• Buildings insurance
• Ground rent and service charges (for leasehold properties)
• Mortgage interest — subject to the Section 24 restriction (a basic rate 20% credit only applies for individual landlords since April 2020)
• Accountancy and legal costs directly related to the letting

For properties with significant mortgage costs, the Section 24 restriction — which prevents higher-rate relief on mortgage interest — can substantially increase the effective tax rate on rental profits. Understanding the net-of-expenses position is important before deciding whether to retain UK property from abroad.

Frequently asked questions

Do I need to file a UK tax return if I only have pension income? If the NT code is properly in place and the pension is paid to you without UK tax deduction, you may not need to file a return for that income alone. However, if tax has been withheld that you want to reclaim, or if you have other UK income (property, employment, etc.), a return is necessary. HMRC can also require non-residents to file returns in some circumstances — if in doubt, seek advice.

How far back can I claim UK tax reclaims? HMRC allows claims for overpaid tax up to four years from the end of the relevant tax year. Use form R43 for simple interest or savings reclaims; for pension income, a self-assessment return may be required. Claims older than four years are generally out of time.

Is the personal allowance available to all non-residents? No. Non-residents are only entitled to the UK personal allowance (£12,570 as of 2026) if they are a UK national, a national of a European Economic Area country, or if their country of residence has a UK double tax treaty provision granting it. A number of UK treaties — including with the UAE, which has no income tax itself — do not grant a personal allowance to non-residents. Check your specific treaty.
