Taxes in Portugal for American Retirees
Taxes in Portugal
When Portugal starts taxing you, how it treats a U.S. pension, and what the United States still expects from you regardless.
When you become tax resident
You become Portuguese tax resident if you spend more than 183 days in Portugal in any twelve-month period, or if you keep a home there in circumstances implying an intention to hold it as a habitual residence.
How your foreign pension is treated
Once tax resident, foreign pension income is generally taxable in Portugal at progressive rates. The original non-habitual resident regime, which taxed foreign pensions at a flat 10 percent, is closed to new arrivals. The successor incentive is aimed at scientific research and innovation activity and does not assist a retiree.
The U.S. tax treaty position
The United States and Portugal have an income tax treaty. U.S. Social Security is dealt with specifically, and the Foreign Tax Credit generally prevents genuine double taxation, but the treaty does not exempt you from filing in either country.
Wealth tax
No general wealth tax. There is an additional municipal property tax, AIMI, on high-value Portuguese property holdings above a threshold.
Other taxes and reporting
Property transfer tax (IMT) and stamp duty apply on purchase and are significant. Annual municipal property tax (IMI) is modest. There is no inheritance tax between spouses, descendants and ascendants, though a stamp duty applies to other beneficiaries.
Remember the U.S. side
The United States taxes its citizens on worldwide income wherever they live. Moving does not end your filing obligation, and FBAR reporting is triggered by an aggregate of 10,000 dollars across foreign accounts at any moment in the year.
