IMT (Imposto Municipal sobre Transmissões): Portugal’s property transfer tax, paid by the buyer before the deed is signed at the notary. Rates use a sliding scale with deduction adjustments — meaning the effective rate is non-linear. Primary residences (where you have your fiscal address) benefit from lower brackets.

Imposto de Selo: stamp duty, a flat 0.8% on the higher of declared price or VPT (cadastral value). Paid at the same time as IMT.

Above €1,128,287: flat rates of 6% (urban) / 7.5% (other) apply — the sliding scale stops compounding above this threshold.

Not included here: annual IMI (Imposto Municipal sobre Imóveis, 0.3-0.45% of VPT), legal fees (~1.5%) and the AIMI surcharge on properties over €600k. The full Outpost dossier calculates all of these.

FAQ

Frequently asked questions

How is IMT calculated in Portugal?

IMT is a sliding-scale property-transfer tax that depends on the price, whether the property is urban or rural, and whether it is your primary residence; a flat rate applies above €1M. Imposto de Selo (stamp duty) is added on top. The calculator applies the 2026 scale. Figures are indicative and current as of 2026 — always confirm with a qualified local professional before you commit.

What is Imposto de Selo when buying property in Portugal?

Imposto de Selo is Portuguese stamp duty charged on the purchase, separate from and in addition to IMT. The tool shows both so you see the combined figure.

Do non-residents pay more IMT in Portugal?

IMT itself is charged on the property, not the buyer's residency, so the rate is the same — but the primary-residence reductions generally require the home to be your own permanent residence.
