Are you paying tax in the right country?

Tax residency in Portugal is determined by spending 183 days or more in the country during any 12-month period, or by maintaining a home that functions as your habitual residence. Residents are liable for tax on worldwide income, with income tax rates ranging from 12.5% to 48% in 2026, plus surcharges, and investment income generally taxed at 28%. If you have connections to the UK, you must also navigate the UK's Statutory Residence Test (SRT) and the UK-Portugal double taxation treaty to avoid double taxation or compliance issues.
