Why £500k can produce another answer
Retirement age, asset access, State Pension, DB income and spending matter. Portugal may not recognise ISA tax-free treatment, and Portuguese personal tax is not calculated.
Tax framework and limitations
Portugal is framework-only, not fully modelled. The current UK–Portugal treaty and resident-tax framework are recorded for State Pension and ordinary pensions. Flexible DC withdrawals, lump sums, government-service pensions, investments, UK property and treaty relief require individual analysis. Portugal may not preserve ISA tax-free treatment.
Healthcare and residence
Residents may access the SNS, and eligible UK State Pension recipients may register an S1. Eligibility is not guaranteed; pre-registration private cover and user costs remain editable allowances. Visa and residence-card qualification are not assessed. This is not tax, legal, immigration or healthcare advice.
Portugal is not one cost profile
Algarve and Madeira have different housing, travel and island-access assumptions. RetirementInSight models supported financial inputs; WhereCanIRetire helps decide which place may suit you.
