UK Double Taxation Agreements and Pension Income: Country-by-Country Guide

For UK expats drawing pension income from a SIPP, a defined benefit scheme, or the State Pension, the double taxation agreement (DTA) between the UK and their country of residence is one of the most financially significant documents in their lives — even if they have never read it. The DTA determines whether UK income tax is deducted from their pension at source, whether they pay tax once or potentially twice, and which country's tax rates apply to their retirement income.

In this guide we provide a country-by-country overview of the DTA position for pension income across the markets where our clients are most commonly based. This is intended as an orientation, not a substitute for specific professional advice — DTA provisions can be complex, and the interaction with domestic tax law in both countries requires careful analysis. Positions described here reflect our understanding as of June 2026.

What a DTA Does — and What It Doesn't Do

A double taxation agreement is a bilateral treaty between two countries. It does not reduce tax to zero or create a tax exemption — it allocates taxing rights. The pension income article in a DTA will typically do one of three things:

Assign exclusive taxing rights to the country of residence: The UK gives up its right to tax the income. The recipient can apply for an NT code (via Form DT Individual) and receive the pension gross. Tax is paid only in the country of residence.

Assign exclusive taxing rights to the UK: The UK retains the right to tax the income regardless of where the recipient lives. This is the typical outcome for government service pensions — civil service, armed forces, NHS, police, teachers — under most DTAs.

Allow both countries to tax, with a credit mechanism: Both countries can impose tax, but the country of secondary taxing right must give a credit for tax paid in the primary country. The overall tax burden is typically determined by the higher of the two countries' rates.

In most cases, we are working with clients to achieve the first outcome: exclusive residence-country taxation, an NT code from HMRC, and the pension paid gross.

The NT Code and Form DT Individual: The Mechanics

To receive a UK pension without UK income tax deducted, the pension provider must be instructed by HMRC to pay gross. This instruction takes the form of a PAYE code of "NT" (No Tax), issued by HMRC following a successful DTA relief application.

The application is made via Form DT Individual. This form requires:

• Personal details of the pension recipient
• Details of the pension(s) in question, including the name and contact details of each provider
• Confirmation of residence and tax status in the receiving country, certified by the local tax authority

The certification step is often the most time-consuming. The recipient must obtain a stamp or signature from the tax authority in their country of residence — confirming that they are a tax resident there and subject to that country's tax law. Processing times vary: in Spain, Cyprus and Greece this is typically straightforward; in Thailand and Indonesia it may take longer.

Once HMRC approves the claim and issues the NT code to the provider, the pension is paid gross. Any UK income tax deducted before the NT code was in place can be reclaimed via a self-assessment return or Form R43.

Spain

DTA: UK-Spain DTA, updated 2013. Pension income article: Private pension income (including SIPPs, personal pensions and workplace DC schemes) is taxed exclusively in Spain for Spanish residents. UK income tax is eliminated via the NT code. Government service pensions: Taxed in the UK only. Former UK civil servants, teachers, NHS workers and others who receive government service pensions continue to pay UK income tax on them, even as Spanish residents. Spanish tax treatment: Spain applies a progressive income tax system. National rates range from 19% to 47% on taxable income, with regional variations by autonomous community. UK pension income is included in the general income tax base. Planning note: Spain is one of the clearest and most straightforward DTA positions for UK pension recipients. The NT code application is well-understood by Spanish tax advisers, and the process is relatively smooth. Clients moving to Spain should apply for the NT code as part of their pre-move planning.

Cyprus

DTA: UK-Cyprus DTA, updated 2018. Pension income article: The DTA gives Cyprus the right to tax UK pension income, with the UK retaining taxing rights on the first approximately £3,430. For most clients, the practical effect is that the majority of their pension is taxable only in Cyprus. Cypriot tax treatment: Cyprus offers a particularly attractive option for foreign pension income. Under Cyprus domestic law, foreign-source pension recipients can elect to pay a flat rate of 5% on pension income above an exempt threshold (raised to €5,000 under the 2026 Cyprus tax reform, from approximately €3,420 previously). Alternatively, they can be taxed at normal Cypriot income tax rates (0–35%), which may be lower depending on total income. The 5% election is widely used and makes Cyprus one of the most tax-efficient jurisdictions for UK pension recipients in Europe. Government service pensions: Taxed in the UK only, as under most DTAs. Planning note: For clients considering retirement to Cyprus, the combination of the favourable DTA and the 5% pension election can produce a very low effective tax rate on UK pension income. This is a significant factor in our planning discussions with clients interested in Cypriot residence.

United Arab Emirates (UAE)

DTA: UK-UAE DTA, in force since 2016. Pension income article: This is one of the more complex and less clear positions. The UAE has no personal income tax, which creates an unusual situation: there is no country-of-residence tax to substitute for UK tax. The UK-UAE DTA does not contain a broadly worded pension income article that clearly eliminates UK taxing rights for all private pension income received by UAE residents. Practical position: UK pensioners living in the UAE may continue to pay UK income tax on their pension income. The DTA does provide some relief in specific circumstances, but private pension income is not always covered in the same way as it is in DTAs with countries that have their own income tax systems. Planning approach: For clients considering the UAE as a retirement destination, the pension tax position requires specific professional analysis. Some clients explore alternative structures — including QROPS transfers to a jurisdiction with a clearer DTA position — as part of their planning. We advise UAE-based clients to obtain specialist UK and UAE tax advice before assuming their pension will be free of UK income tax.

Thailand

DTA: UK-Thailand DTA, in force since 1981. Pension income article: The DTA generally assigns taxing rights over pension income to Thailand for Thai residents. An NT code can be applied for and pension income paid gross from the UK. Thai tax treatment: Thailand imposes income tax at progressive rates from 0% to 35%. Foreign-source income brought into Thailand in the year of receipt is assessable; income brought in subsequent years may be treated differently under domestic Thai rules. Clients receiving UK pension income while resident in Thailand should take advice from a Thai tax specialist to ensure compliance with Thai domestic rules. Planning note: Thailand is a well-established retirement destination for UK expats, and the DTA position is workable, though the Thai tax rules require careful management.

Greece

DTA: UK-Greece DTA, signed 1953, modernised provisions. Pension income article: The DTA gives Greece the right to tax UK pension income for Greek residents. NT code relief is available. Greek tax treatment: Greece has in recent years introduced a preferential tax regime for individuals transferring their tax residence to Greece — including a flat tax rate of 7% on foreign-source income (including pensions) for a period of up to 15 years. This regime, introduced in 2020, is available to non-Greek-tax-residents who have lived outside Greece for at least 7 of the 8 years prior to transferring residence. For UK expats retiring to Greece who qualify, this can represent a very significant reduction in the effective tax rate on UK pension income. Planning note: The Greek flat-tax regime for foreign pensioners is one of the more attractive incentives in Southern Europe. Clients considering Greek retirement should model their pension income position carefully, taking both the DTA and the domestic Greek rules into account.

Egypt

DTA: UK-Egypt DTA, signed 1980. Pension income article: The DTA provides for pension income to be taxed in the country of residence — Egypt for Egyptian residents. NT code relief is available in principle. Egyptian tax treatment: Egypt imposes income tax at progressive rates. The domestic tax rules and any exemptions or allowances available to foreign-source income recipients should be verified with an Egyptian tax adviser. Planning note: Egypt is a market of growing interest for our clients, particularly for property investment. Clients who are or become Egyptian tax residents should address the pension income tax position as part of their broader financial planning.

Indonesia (Bali)

DTA: UK-Indonesia DTA, signed 1993. Pension income article: The DTA exists but its pension income provisions are more limited than many other UK treaties. The specific allocation of taxing rights for different types of pension income requires careful analysis. Practical position: Clients who are Indonesian tax residents receiving UK pension income should obtain specific professional advice — both from a UK pension and tax specialist, and from an Indonesian tax adviser — before assuming that the DTA eliminates UK income tax. The position is not as clear-cut as in Spain or Cyprus. Planning note: Many of our clients with interests in Bali are investors rather than permanent residents. For those who are or become tax-resident in Indonesia, pension income planning is an important and complex consideration.

United States of America

DTA: UK-US DTA, comprehensively updated 2001, modified by subsequent protocols. Pension income article: The UK-US DTA is one of the most detailed bilateral treaties in the world. Private pension income (including SIPPs and personal pensions) received by US residents is generally taxable in the USA rather than the UK. The treaty contains specific provisions for state pensions and government service pensions as well. US tax treatment: The US imposes income tax at federal level (10–37% for 2026) and often at state level as well. UK pension income is generally includable in US gross income. Foreign tax credits may be available for any residual UK tax. Planning note: US persons (US citizens, green card holders and US residents) face some of the world's most complex international tax obligations, and the interaction between UK pension rules and US tax requirements — including FBAR reporting, FATCA, and the specific PFIC and trust rules that may apply to SIPPs — requires expert advice from a dual-qualified US/UK tax specialist.

The State Pension and DTAs

The UK State Pension is covered by most double taxation agreements, and non-residents can in principle claim DTA relief so that it is taxed only in their country of residence. However, the State Pension cannot have an NT code applied to it in the same mechanical way as a SIPP or personal pension. The DWP pays the State Pension gross, and the UK income tax on it is typically collected through self-assessment or through the PAYE code on another pension. Non-residents who are entitled to DTA relief on their State Pension income can reclaim overpaid UK tax via their self-assessment return or Form R43.

Compliance: The Obligations Do Not End with the NT Code

Obtaining an NT code and receiving a pension gross does not end the compliance obligations. Non-residents with UK pension income are typically required to:

• File a UK self-assessment return (depending on individual circumstances)
• Declare the pension income in the tax return of their country of residence
• Ensure that the NT code remains current and that the DT Individual claim is renewed if required

We always advise clients that the NT code is the beginning of a compliance regime, not the end of one.
