# UK expat tax in Portugal [Moving to Portugal](/moving-to-portugal/) Guide Law as at 19 October 2026 6 min read [Signed by our advisers](/about/) · 4.7 on Google, 43 reviews In short A UK State Pension or private pension paid to a Portuguese resident is taxed only in Portugal, under the ordinary pension rule in the 2025 UK-Portugal convention, in effect in Portugal since 1 January 2026. - A UK government-service pension stays taxable only in the UK; if you are a Portuguese national and not a UK national, both countries can tax it. - An ISA's UK exemption does not apply in Portugal. **Works with your UK accountant.** Taxbordr documents the Portugal-side position and works with your UK adviser on the coordination points, including the treaty and, where HMRC's statutory conditions are met, split-year treatment, so the two filings can be aligned. Most British filings turn on [UK-Portugal treaty](/insights/uk-portugal-double-taxation-treaty-guide/) rules, pension treatment, and investment income. ## Which UK-Portugal treaty rules apply to your case? The 2025 convention entered into force on 29 December 2025. It applies in Portugal from 1 January 2026; in the UK, from 1 January 2026 for withholding taxes, 1 April for Corporation Tax and 6 April for Income Tax and [Capital Gains Tax](/guides/capital-gains-tax-portugal/). The earlier convention remains relevant to periods before the effective date for the tax concerned. Apply domestic residence tests first. If both countries claim residence, test the applicable treaty tie-breaker using the facts for the relevant period. Citizenship alone does not determine Portuguese tax residence. | Record | What to retain | | --- | --- | | Residence timeline | Arrival/departure dates, nights in each country and the date each home became available or ceased to be available. | | Personal and economic ties | Family location, work and business management, with evidence of the circumstances that changed. | | Income periods | Payer statements identifying payments and tax withheld before and after the relevant residence dates. | | Filing position | The treaty version, article and relief method for each income stream, shared with the people preparing each return. | ## How are UK State, private, and government pensions taxed in Portugal? A UK pension paid to a resident of Portugal is taxed only in Portugal, as pension income at the progressive IRS rates (12.5% to 48% in 2026), unless it is a government-service pension. Under the 2025 UK-Portugal treaty, which applies from 2026: - UK State Pension: taxable only in Portugal. - Private and workplace pensions: taxable only in Portugal. UK PAYE continues until HMRC grants relief, as explained below. - Government-service pensions, such as civil service, armed forces and police pensions: taxable only in the UK, unless you are a Portuguese national and not a British one. In that case both countries may tax them, and Portugal credits the UK tax. With NHR, a UK pension is taxed at 10% until your ten years end. Holders registered, or already resident, before April 2020 keep the earlier exemption, unless they chose the 10% rate in their 2020 return. IFICI does not cover pensions. ### Is my UK State Pension taxable in Portugal? For a treaty resident of Portugal, the UK State Pension and private pensions covered by the treaty’s ordinary pension rule are taxable only in Portugal. Portuguese tax then depends on domestic rules and any applicable transitional regime. The State Pension is distinct from a government-service pension. ### How are UK government pensions taxed in Portugal? Under the government-service pension rule, a covered pension for service to the UK government is normally taxable only in the UK. If the recipient is a Portuguese national and is not a UK national, both states may tax it; the treaty’s double-tax relief must then be considered. Services connected with a government business fall under the treaty’s government-business exception. ### NHR legacy and IFICI interaction with pensions NHR is closed to new entrants, apart from the NHR transitional cases, and legacy holders may still have remaining regime years that affect domestic treatment. IFICI is a separate post-NHR framework for qualifying profiles. Regime eligibility and treaty allocation are different tests: one determines domestic treatment, the other determines taxing-right allocation. ### Claiming UK PAYE relief on a private pension Where the treaty makes a UK private or occupational pension taxable only in Portugal, UK PAYE withholding does not stop automatically. Relief is claimed from HMRC on form DT-Individual, which covers both relief at source and a repayment of UK tax already deducted. The Portuguese tax authority does not certify the form, so the claim must include a separate Portuguese certificate of tax residence from the Portal das Finanças. HMRC decides the claim and, where appropriate, authorises relief or a repayment; the timing depends on its processing.

Beyond pensions, UK-sourced investment income follows its own treaty rules. ### Are UK ISA investments taxable in Portugal? For a Portuguese resident, the relevant question is how the underlying income or gain is classified and reported in Portugal, not whether the account keeps its UK label. ### How does Portugal tax UK dividends and interest? For an ordinary Portuguese resident, dividends and interest generally fall within Category E and the 28% special-rate framework, with aggregation options and statutory exceptions. Qualifying IFICI foreign-source income can instead be exempt with progression, subject to the listed-jurisdiction rule. A UK ISA does not by itself exempt its underlying income in Portugal. Establish any actual UK tax and the applicable treaty limit before claiming Portuguese credit; do not treat an assumed UK withholding percentage as tax paid. ### UK rental income and property gains after relocation If UK property is kept after the move, rental income and later disposals should be planned as separate tracks. ## How to sequence the two filings Dual filing means two tax returns in two countries, each reflecting consistent treaty positions. 1. ### Confirm the tax periods Record residence dates, the Portuguese calendar year and the overlapping UK tax periods. 2. ### Reconcile income and credits Use one income, exchange-rate and foreign-tax schedule for both returns; explain differences in timing and classification. 3. ### Agree the filing order Each preparer confirms their filing deadline, the inputs they need and who handles treaty-relief claims. ## Five common filing mistakes - Treating all pensions as one category - Reading the treaty without the Portuguese rules - Filing UK and Portugal with inconsistent values - Leaving evidence collection to filing month - Overlooking property, ISAs and mixed income ## Special focus for founders and self-employed UK expats Business income planning requires separate checks for activity classification, deductible expense discipline, [VAT](/guides/vat-tax-portugal/) scope, and social-security obligations. ## Frequently asked questions ### Do UK citizens pay tax in Portugal? Yes, if they are Portuguese tax residents. Residents are generally taxed on worldwide income under Portuguese IRS rules, while treaty provisions and foreign-tax-credit mechanics are used to claim double-taxation relief with the UK. ### How are UK expats taxed in Portugal? The answer depends on your tax residence and the type of income. A pension, dividends, interest, a property gain and rent can each follow different Portuguese rules and treaty treatment. ### Will my UK ISA income still matter for Portuguese tax? Yes. UK ISA tax relief does not itself exempt the income in Portugal. ### What is the 183-day rule in Portugal for UK expats? One residency trigger under Portuguese tax-residence rules is spending more than 183 days in Portugal in any 12-month period beginning or ending in the relevant tax year. Habitual residence can also matter, so the day count should not be treated as the only test. ### Do I still pay UK tax if I live in Portugal? It depends on the income category. Some UK-source income may still be taxed in the UK, while treaty allocation and credit mechanisms coordinate overall taxation with Portugal. ### Do I need to file in both countries? Often, yes, depending on where you are resident and the income you receive. The two returns need consistent income figures and the correct treaty relief or credit for tax paid, so the same payment is treated consistently in both countries. ### What is IFICI and how does it differ from NHR? NHR is closed to ordinary new entrants, apart from the transitional cases. IFICI is a separate regime for qualifying work and has different eligibility conditions. ### What happens if I miss Portuguese filing deadlines? Late filing or payment can trigger fines, default interest, and procedural escalation. ### How is UK rental income treated after moving to Portugal? UK rental income may remain taxable in the UK while also reportable in Portugal for residents. ### Do I need to notify HMRC when I move to Portugal? HMRC has official departure and residence procedures, including form P85 in some cases.
