IMT is the transfer tax due when buying property in Portugal. It is not the agency fee and not the annual IMI. It is settled at the deed, usually in conveyancing.

They are separate taxes. IMT follows progressive tables by purpose and value. Stamp Duty on onerous property acquisition is typically 0.8% on the same base (price or VPT, whichever is higher).

Primary permanent residence uses progressive brackets, plus the youth IMT regime when eligible. Secondary home or rental uses the non-HPP housing table. A shop, office, commercial space or urban building that is not housing pays a flat 6.5%. Rural property pays 5%. “Other purposes” are not automatically more expensive: above about €1.15m on the mainland, housing reaches 7.5% — higher than the 6.5% non-housing rate. Picking the wrong purpose in the calculator skews the result — match it to real use at the deed.

Exemption/reduction regimes exist (including for younger buyers on a primary residence, under current legal conditions). Rules change with the State Budget — always confirm eligibility before assuming an exemption.

Beyond IMT + Stamp Duty, plan for notary/land registry fees, possible bank valuation, mortgage costs and brokerage if applicable. The CRT calculator covers IMT + Stamp Duty; notary, registry, lawyer and mortgage extras are in the buying-costs guide.
