Expat Pension Withholding Treaties 2026

The OECD Model Tax Convention (MTC), which underlies most bilateral tax treaties, has Article 17 (private pensions) assign primary taxing rights to the country of residence — the country where the retiree lives, not where they accumulated the pension. Government pensions (Article 18) are typically taxed in the source country (where they were earned). In practice: a UK state pension received by someone living in the Netherlands is taxable in the Netherlands (as residence country) under the UK-NL DTA, and the UK does not withhold tax. A UK private pension (SIPP) received in Germany: Germany as residence country taxes it; UK does not withhold (UK's general approach under most treaties is to give up source-country right to tax private pensions). Without a treaty, the source country may withhold 15-25% — creating double tax. Treaty planning is essential for retirees living in a different country from where they earned their pension.

The UK state pension is paid gross (without withholding tax) to recipients worldwide — the recipient declares it in their country of residence and pays local income tax. However, the UK's policy of 'uprating' the state pension (raising it annually via the triple lock) only applies in countries with which the UK has a relevant bilateral social security agreement or in EEA/Switzerland. In approximately 150 countries — including Australia, Canada (provinces other than Quebec), New Zealand, India, and Pakistan — UK state pensioners receive the same fixed amount they received when they first claimed or first moved to that country, with no annual increases. A person who left for Australia in 2000 and received £70/week still receives £70/week in 2026 — not the current £230.25/week. This 'pension freeze' affects approximately 500,000 UK state pensioners abroad. It is one of the longest-standing pension policy injustices campaigned about, but the UK government has consistently refused to change it.

Portugal's Non-Habitual Resident (NHR) regime, introduced in 2009, was the most popular European pension tax planning destination for a decade. For qualifying new residents, foreign-sourced pension income was taxed at a flat 10% rate (replacing marginal Portuguese rates of up to 48%). French, Dutch, German, and UK pensioners relocated to Portugal in large numbers specifically for this treatment. The 2024 Portuguese Budget (October 2023) announced NHR abolition for new applicants from January 2024 (existing NHR recipients' 10-year period was protected). The replacement IFICI (Incentivo Fiscal à Investigação Científica e Inovação) scheme is targeted at researchers, qualified professionals, and startup entrepreneurs — not retirees. Most new-entrant retirees from 2024 onwards face standard Portuguese income tax rates on foreign pension income. This eliminated one of Europe's most significant retirement tax planning jurisdictions overnight.
