Stamp Duty Calculator (Portuguese Imposto do Selo)
How much Stamp Duty (Imposto do Selo) do you pay when buying a home in Portugal? You pay it twice: 0.8% on the purchase value and, if you take a mortgage, 0.5%–0.6% on the loan amount. This calculator estimates both parts and the total, from the deed price (or the VPT, if higher) and the credit.
The acquisition duty is charged on the higher of the deed price and the VPT (0.8%). If you buy with a mortgage, you also pay duty on the loan: 0.6% for terms of 5 years or more. Set the loan to 0 if buying with cash.
How the Stamp Duty is reached
| Duty on the acquisition (0.8%) | €2,000.00 |
| Duty on the credit (0.6%) | €1,200.00 |
| = Stamp Duty to pay | €3,200.00 |

What Stamp Duty is
Imposto do Selo (Stamp Duty) is a tax on a wide range of acts, contracts and documents: from buying property to credit, rentals, inheritances and some bank fees. The rates sit in the General Stamp Duty Table (TGIS), annexed to the Stamp Duty Code. This calculator focuses on the most common and most expensive case: the duty you pay when buying a home.
The two stamp duties of buying a home
Buying a home means paying Stamp Duty on two fronts, both at the deed. First, duty on the acquisition (TGIS item 1.1): 0.8% on the higher of the deed price and the property’s taxable value (VPT), the same base as IMT. Second, if you buy with a mortgage, duty on the use of credit (TGIS item 17.1): charged on the amount financed, at a rate that depends on the term.
The credit duty rates
The credit duty rate depends on the loan term: 0.60% for loans of 5 years or more (the normal mortgage case), 0.50% between 1 and 5 years, and 0.04% per month for terms under a year. Since a mortgage almost always runs 25–40 years, the 0.60% rate applies to the amount borrowed. A cash buyer, with no credit, pays only the 0.8% acquisition duty.
Worked example
Someone buying a home for €250,000 (with a lower VPT) and financing €200,000 over 30 years pays: €250,000 × 0.8% = €2,000 in acquisition duty, plus €200,000 × 0.6% = €1,200 in credit duty, a total of €3,200 in Stamp Duty. On top of this there is also IMT, which this calculator does not include (see the IMT calculator).
