UK State Pension and Double Taxation Agreements: A Country-by-Country Guide

One of the most common misconceptions among British expats is that because they no longer live in the UK, they will not owe UK income tax on their state pension. In many cases, this assumption is correct — but in a significant number of countries, the UK retains the right to tax its state pension even when the recipient is resident abroad. Understanding which applies to you is essential to avoiding overpayment of tax, double taxation, or the more common outcome of underpayment and a subsequent HMRC bill.

The Framework: How DTAs Allocate Taxing Rights

A double taxation agreement (DTA) is a bilateral treaty between two countries that determines which country has the right to tax various types of income. Without a DTA, both countries could tax the same income — the DTA prevents this by allocating exclusive or primary taxing rights to one party.

For government pensions — a category that typically includes UK state pension — most DTAs follow one of two approaches:

1. Source-state taxation: The UK (as the source country) retains the right to tax the pension. The country of residence provides relief via a tax credit or exemption.
2. Residence-state taxation: The country of residence has the sole right to tax the pension. The UK pays it gross and HMRC does not collect UK income tax on it.

The key is that you must identify the article in the specific DTA that covers "pensions" or "government service pensions" and determine which approach applies. Note that DTAs do not all use identical language — some have separate provisions for "social security pensions" that differ from private pensions, and the state pension is sometimes caught by a "social security" article rather than a "pensions" article.

A Country-by-Country Summary

Spain

DTA status: UK-Spain DTA 2014 (as amended)

Under the UK-Spain treaty, UK state pension received by a Spanish resident is generally taxable in Spain (residence-state taxation). The UK should pay it gross, and the recipient declares it for Spanish IRPF (income tax).

Spanish income tax rates in 2026 are progressive from 19% to 47% on general income. State pension income for a typical expat falls in the 19–30% band. Spain offers a personal allowance of approximately €5,550 plus age-related supplements.

Practical action: Write to HMRC with evidence of your Spanish tax residency (Spanish tax certificate / certificado de residencia fiscal) to request that your state pension is paid without UK tax deduction. Use form FD9 or the appropriate relief at source form.

France

DTA status: UK-France DTA 2009

Under the UK-France treaty, UK state pension is treated as a government pension and is generally taxable in the UK only (source-state taxation). French residents receive it net of UK PAYE tax where applicable and declare it in France with a foreign tax credit or exemption.

This creates an unusual situation: French-resident UK state pension recipients may actually owe UK income tax, and France will give credit for it rather than taxing the same income again. French residents should ensure their HMRC tax code is applied correctly.

Germany

DTA status: UK-Germany DTA 2010

Under the UK-Germany treaty, UK state pension is generally taxable in Germany (residence-state taxation). The UK should pay it gross for German residents. Germany's income tax rates in 2026 are progressive; the first €11,604 of income (approximate figure) is exempt.

USA

DTA status: UK-USA DTA 2001 and Protocol

Under the UK-US treaty, UK "social security pensions" — which includes the state pension — fall under a specific article. The treaty generally provides that such payments are taxable only in the state of source (the UK). For UK state pension, this means the UK retains the right to tax it.

For US residents, this creates a cross-border situation: the pension is UK-taxed at source, and the US provides a foreign tax credit on the Form 1116 to avoid double taxation. In practice, UK tax rates on state pension income are often lower than US rates, which can leave a residual US tax liability for some recipients.

US-citizen expats should note that the USA taxes based on citizenship, not residence — meaning even US citizens living in the UK are subject to US tax filing requirements. Get advice from a qualified cross-border tax professional.

Australia

DTA status: UK-Australia DTA 2003**

Under the UK-Australia treaty, UK state pension received by an Australian resident is generally taxable in Australia (residence-state taxation). The UK should pay it gross for Australian residents.

However, there are two important additional considerations:

1. Australian residents receive a frozen UK state pension (no annual uprating, because Australia's social security agreement does not include uprating provisions).
2. Centrelink includes UK state pension as assessable income for the Australian Age Pension means test. A higher or growing UK state pension reduces Age Pension entitlement dollar for dollar above the income threshold.

New Zealand

DTA status: UK-New Zealand DTA 1983 (as amended)

Under the UK-NZ treaty, UK state pension is generally taxable in New Zealand (residence-state taxation). NZ's Inland Revenue taxes it at progressive NZ rates (10.5% to 39% depending on total income).

New Zealand's NZ Superannuation system also includes an abatement that partially offsets overseas pension income. UK state pension recipients in New Zealand should check their NZ super entitlement carefully — the interaction can reduce the benefit of maximising UK state pension.

New Zealand is also a frozen pension country — UK state pension for NZ residents is frozen at the rate at time of claim.

Canada

DTA status: UK-Canada DTA 1978 (as amended)

Under the UK-Canada treaty, UK state pension is treated as "pension income" and is generally taxable in Canada (residence-state taxation for Canadian residents).

Canada has its own CPP (Canada Pension Plan) and OAS (Old Age Security) which interact with UK state pension for means-testing purposes. However, Canada is a frozen pension country — UK state pension for Canadian residents is frozen.

Republic of Ireland

DTA status: UK-Ireland DTA 1976 (as amended)

Under the UK-Ireland treaty, UK state pension received by Irish residents is generally taxable in Ireland (residence-state taxation). Irish income tax rates in 2026 are 20% on income up to approximately €42,000 and 40% above. The Irish pension exemption and age credit can reduce the effective rate significantly for retirees.

Ireland is an uprated country — UK state pension for Irish residents receives annual triple-lock increases.

UAE

DTA status: No comprehensive DTA with the UAE as of 2026

The UK and UAE have not concluded a full DTA. In the absence of a DTA, default UK domestic law applies. Under UK domestic rules, UK state pension is UK-taxable income — the personal allowance reduces the liability for most recipients, but state pension recipients with other UK income may owe UK tax.

For UAE residents, the UAE has no income tax, so no DTA credit is available. This means UK state pension may be subject to UK income tax for UAE residents if their total UK-source income (including state pension) exceeds the UK personal allowance (approximately £12,570 in 2026/27).

The UAE and UK were in DTA negotiations as of 2026 — if a treaty is concluded, the position may change.

Cyprus

DTA status: UK-Cyprus DTA 1975 (as amended)

Under the UK-Cyprus treaty, UK state pension is generally taxable in Cyprus (residence-state taxation). Cyprus is one of the most favourable countries for UK pension income: qualifying non-dom residents can elect to pay a flat 5% tax on overseas pension income above €3,420 per year.

Cyprus is an uprated country — UK state pension recipients in Cyprus receive triple-lock increases.

Greece

DTA status: UK-Greece DTA 1953 (very old, limited scope)

The UK-Greece DTA is one of the oldest in the UK's treaty network. It does not contain modern pension articles. In the absence of clear DTA provisions, the practical treatment for UK state pension recipients in Greece has typically been taxed in Greece under domestic Greek law, with the UK paying gross to Greek residents. Greece's income tax rates in 2026 are progressive (9% to 44%).

Seek specialist advice if you receive UK state pension in Greece — the treaty position is less certain than for newer DTAs.

Thailand

DTA status: UK-Thailand DTA 1981

Under the UK-Thailand treaty, UK state pension received by Thai residents is treated as taxable in Thailand (residence-state). Thailand's personal income tax rates in 2026 range from 0% to 35%. Thailand also has a preferential regime for remittance basis: income not remitted to Thailand in the year of receipt may not be taxed, though this rule has been under review.

Malta

DTA status: UK-Malta DTA 1975 (as amended)

Under the UK-Malta treaty, UK state pension is generally taxable in Malta (residence-state). Malta offers a flat 15% tax rate for those under its Global Residence Programme (GRP) or Malta Retirement Programme (MRP) — highly favourable for UK pension income recipients.

Getting UK Tax Paid Correctly

If your DTA allocates taxing rights to your country of residence, you need to:

1. Apply to HMRC for UK tax not to be withheld — use the appropriate DTA relief form (NT coding application). HMRC will issue a "No Tax" (NT) code to the DWP, and your pension will be paid gross.
2. Obtain a certificate of tax residency from your host country's tax authority — HMRC may require evidence of your foreign tax residence.
3. Declare the income in your host country in the correct tax return, on time.

If your DTA gives taxing rights to the UK, ensure HMRC has the correct PAYE code applied to your state pension. If your only UK income is state pension below the personal allowance, your liability may be nil — but HMRC needs to know your circumstances to confirm this.
