Key IMT and stamp-duty terms, shown in both English and Portuguese.

IMT (Municipal Property Transfer Tax) · IMT (Imposto Municipal sobre as Transmissões Onerosas de Imóveis)
A one-off municipal tax on transfers of property for value, paid by the buyer before the deed is signed.
Stamp duty · Imposto do Selo
A tax on legal acts and documents. On a purchase it is 0.8% of the taxable value (TGIS verba 1.1), plus a charge on any mortgage (verba 17).
Taxable value (VPT) · VPT (Valor Patrimonial Tributário)
The tax authority's rateable value of a property. IMT and stamp duty are charged on whichever is higher, the price or the VPT.
Own permanent home (HPP) · Habitação própria e permanente (HPP)
A dwelling that is the buyer's main and permanent residence. It uses a lower IMT table with an exempt first band.
IMT Jovem (young buyers' relief) · IMT Jovem
Relief for a first own permanent home bought by people aged 35 or under: both IMT and the 0.8% acquisition stamp duty are exempt up to a ceiling (€330,539 on the mainland in 2026) and charged only on the excess above it.
Non-resident · Não residente
For IMT, a buyer who is not tax-resident in Portugal. Since 2026 they pay a flat 7.5% on housing (CIMT art. 17.º n.º 10), unless an exception applies.
Tax haven · Paraíso fiscal
A jurisdiction on Portugal's blacklist. An entity domiciled there pays a flat 10% IMT (art. 17.º n.º 4); this does not apply to individuals.
Rate and deduction · Taxa e parcela a abater
IMT is progressive: tax = value × the band's marginal rate − a fixed deduction that keeps the bands continuous.
Flat rate · Taxa única
For high-value property the progressive bands give way to a single flat rate applied to the whole value.
Co-ownership & the totality rule · Compropriedade e a regra da totalidade
When several buyers acquire the whole property in one deed, the rate is set by the total value and applied to each share (art. 17.º n.º 6 a) — buying together gives no band-splitting advantage.
Deed · Escritura
The notarial contract that transfers the property. IMT and stamp duty must be paid before it is signed.
Moderate rent · Renda moderada
A rent within the limits of Decreto-Lei n.º 97/2026. A non-resident who lets the home at moderate rent can reclaim the 7.5% surcharge down to ordinary rates.
Tax Authority (AT) · Autoridade Tributária e Aduaneira (AT)
Portugal's tax and customs authority, which assesses and collects IMT and stamp duty.
