Are you paying too much property tax in Portugal?

Homeowners can request a reassessment of their property's tax value (VPT) to potentially reduce their annual IMI tax bill. DECO PROteste advises using its online simulator before filing a request with the Tax Authority, as a reassessment can also lead to an increased valuation. Requests submitted by 31 December can affect the IMI bill due in 2027, but will not change the payments due in November 2026. The base value per square metre for valuations rose to 712.50 euros in 2026, which may offset tax reductions typically associated with a building's age.
