How the brackets stack (primary residence, mainland, 2026)
0% 106 346 € 2% 145 470 € 5% 198 347 € 7% 330 539 € 8% 660 982 € Each slice of the price pays its own bracket’s rate — that is what the deductible portion (parcela a abater) solves for you. Above 660 982 € there are no more brackets: a flat 6% (up to 1 150 853 €) or 7.5% applies to the whole price.

How the calculation works

IMT (Imposto Municipal sobre as Transmissões Onerosas de Imóveis — the property transfer tax) is not a single rate on the price: the value climbs through brackets and each slice pays its own bracket’s rate. So you don’t have to add up slice by slice, the official tables give you a deductible portion (parcela a abater): multiply the price by the marginal rate and subtract it. A €180,000 primary residence on the mainland pays €180,000 × 5% − €6,491.02 = €2,508.98 — an effective rate of 1.4%, not 5%.

Above €660,982 the system changes: a flat rate (6% or 7.5%) applies to the whole price. And there are three different tables — primary residence, second home or rental, and the autonomous-regions versions with brackets 25% higher.

The purchase stamp duty (Imposto do Selo) is always 0.8% of the same value. If you are 35 or under and this is your first home, the under-35 scheme (regime jovem) exempts both taxes up to €330,539 — but it does not exempt the stamp duty on the mortgage (0.6% of what you borrow), a cost almost everyone forgets.

These two taxes are only part of the initial outlay. For the full picture — deposit, registration, commissions — use the total purchase costs calculator.

Frequently asked questions

Is IMT calculated on the price or on the taxable value (VPT)?
On the higher of the two. If you buy for €220,000 and the property’s taxable value (VPT, on the caderneta predial) is €180,000, IMT is charged on €220,000. If the VPT were €240,000, it would be charged on the VPT.
How much do I pay on a €250,000 primary residence on the mainland?
In 2026: IMT = €250,000 × 7% − €10,457.96 = €7,042.04, plus €2,000 of stamp duty (0.8%). Total: €9,042.04. Under the under-35 scheme it would be €0.
I am 35 or under — up to what price am I exempt in 2026?
Full exemption from IMT and purchase stamp duty up to €330,539 (mainland). Between €330,539 and €660,982 you pay 8% IMT and 0.8% stamp duty only on the excess. Above that, the benefit disappears. Conditions: first primary residence, no residential property in the last 3 years, and not a tax dependant in the year of purchase. Note: the stamp duty on the mortgage (0.6%) is always due.
When and how is IMT paid?
Before the deed. You request the payment slip (DUC) on the Portal das Finanças or at a tax office, pay it, and bring the proof to the notary or Casa Pronta desk on signing day.
Are the rates different in the Azores and Madeira?
Yes. The autonomous regions’ brackets are 25% higher: the primary-residence exemption runs to €132,933 and the under-35 scheme to €413,174 (2026). The calculator applies the right tables when you pick “Azores / Madeira”.
