IMI 2027: up 3% on homes after the automatic value update
A portaria published in the Diário da República (n.º 457/2026/1) sets the currency coefficient used by the Tax Authority in the automatic three-yearly update of a property's taxable value (VPT). For homes and building land the value rises 3%; for shops, offices and industry, 4%. It only affects properties due for that update and the IMI charged in 2027 for 2026. Municipal IMI rates do not change: as ECO puts it, a €500 IMI bill would become €515. In the previous cycle the rise was 4.5% for homes.
Why it matters for your move
If you own a home, you can ask the Tax Authority for a new valuation, which can lower the VPT as the building ages (key years: 9, 16, 26, 41, 51 and 60 years after the use licence). Ask by 31 December for it to count next year, and only if you have not asked for the same property in 2024 to 2026. Simulate first: according to DECO PROteste, a new valuation can also raise the value.
