Portugal has a progressive tax system with high rates reaching up to 48%. The popular Non-Habitual Resident (NHR) regime, which offered significant tax exemptions for 10 years, was largely phased out for new applicants in 2024, replaced by a stricter incentive for specific professionals. There is no general wealth tax, but an additional property tax (AIMI) applies to real estate portfolios valued over 600,000 EUR.
Tax residents in Portugal are taxed on their worldwide income. While a US-Portugal tax treaty exists to mitigate double taxation, it does not perfectly shield all income types. For instance, US LLCs are often treated opaquely and taxed heavily. US citizens must continue to file US taxes, utilizing the Foreign Tax Credit or Foreign Earned Income Exclusion to offset liabilities.
The cost of living is significantly lower than in the US, though it has risen sharply in expat hubs like Lisbon, Porto, and the Algarve. The housing market is highly competitive. Landlords frequently require expats without a Portuguese guarantor to pay anywhere from 3 to 12 months of rent upfront as a deposit.
Portugal ranks as one of the safest countries in the world. It is highly welcoming to foreigners and boasts excellent LGBTQ+ safety and rights. While English is widely spoken in urban areas and the Algarve, learning Portuguese is highly recommended for integration and is a requirement for obtaining permanent residency or citizenship after five years.
