IMT Portugal Calculator 2026

IMT (Imposto Municipal sobre as Transmissões Onerosas de Imóveis) is the property transfer tax paid when buying real estate in Portugal. It's calculated on the higher of the purchase price or VPT (tax value). The rate depends on property type (urban vs rural), intended use (primary residence, secondary, or rental), and location (mainland vs Azores/Madeira). IMT is a one-time tax paid at purchase — not to be confused with annual property taxes like IMI. For most residential purchases, rates range from 0% to 8% using progressive brackets, though properties above certain thresholds may be subject to flat rates of 6% or 7.5%. Non-residential urban property is taxed at a flat 6.5% and rustic land at 5% — both available as categories in the calculator's Advanced mode.

Both IMT and stamp duty (Imposto de Selo) must be paid before signing the deed (escritura) at the notary. This is a strict legal requirement — the notary cannot proceed without proof of payment. The process starts with the Modelo 1 do IMT declaration (filed online, at any tax office, or often by the notary): it triggers the assessment and generates the DUC (Documento Único de Cobrança) reference, and it is mandatory in every purchase — not only when claiming a benefit. You can then pay at any tax office (Finanças) or online via Portal das Finanças using that DUC reference. Payment is due on the day the assessment (liquidação) is issued or within the following 30 days — but always before the deed, because the notary cannot proceed without proof of payment (arts. 36.º and 49.º CIMT). Keep your payment receipts safe — the notary will need them, and they serve as proof for your records.

VPT (Valor Patrimonial Tributário) is the property's official tax value registered with the Portuguese Tax Authority (Autoridade Tributária). IMT is calculated on the higher of the purchase price or VPT — so if VPT exceeds your agreed price, you'll pay more tax than expected. This commonly happens with undervalued properties or those that haven't been reassessed recently. You can find VPT in the Caderneta Predial (property certificate) available on Portal das Finanças or request it from the seller before making an offer. Always check VPT early in your buying process to avoid surprises at the notary. Note: this calculator's Basic mode deliberately keeps things simple and uses the purchase price as the tax base — switch to Advanced and enter the VPT to have max(price, VPT) applied.

Primary permanent residence (HPP — Habitação Própria e Permanente) benefits from lower tax brackets and an exemption threshold: in 2026, properties up to €106,346 on the mainland pay 0% IMT. Secondary homes, holiday properties, and rental investments pay tax from the first euro at higher rates with no exemption. The difference is modest but real — on a €300,000 mainland property, HPP saves €1,063.46 (€10,542.04 vs €11,605.50 in 2026); the big savings come from IMT Jovem, which can eliminate the bill entirely. To qualify for HPP, you must intend to live in the property as your main residence; this is declared on the Modelo 1 do IMT form before the deed.

If you buy with a partner or co-owner over 35, the IMT Jovem exemption applies proportionally to your ownership share only. For example, if you're 30 and own 50%, and your partner is 40 and owns 50%, only your half benefits from IMT Jovem rates — your partner pays standard HPP rates on their share. Use our Advanced mode calculator to model this scenario precisely. Note that both buyers must meet all other eligibility criteria for their respective portions: you must not have owned a home in the last 3 years, not be a tax dependent, and the property must be for primary residence (HPP).

The simulation starts from the purchase price — or the VPT, when it is higher — and applies the official 2026 brackets: the base is multiplied by the bracket rate and the bracket's deduction (parcela a abater) is subtracted. The stamp duty calculation is added on top: 0.8% on the purchase and, with a mortgage, 0.6% on the loan for terms of 5 years or more. Advanced mode simulates two buyers with different shares, companies and non-residents.

No. The purchase stamp duty (verba 1.1) is 0.8% of the taxable base — the higher of the price and the VPT. The mortgage stamp duty (verba 17.1) is separate: 0.6% for terms of 5 years or more, 0.5% between 1 and 5 years. And under IMT Jovem the first home benefits from a purchase stamp duty exemption capped at €2,644.31.

Yes — Decree-Law 97/2026 also created an IMT exemption for housing sold at controlled costs (EBF art. 45.º-B). It depends on conditions set by each municipality, and this calculator does not model it. See the full answer in the guide.

Yes, significantly. Companies cannot claim HPP (primary residence) rates regardless of the property's use — they always pay secondary/investment rates. Since 25 May 2026, non-residents (individuals or companies) buying residential property pay a flat 7.5% IMT under Decree-Law 97/2026. However, you can apply to have the difference cancelled (anulação) if you become a Portuguese tax resident within 2 years, or if you rent the property at moderate rates (up to €2,300/month in 2026 — 2.5 × the minimum wage — for at least 36 months) — the request must be filed with the Tax Authority within 6 months of the qualifying event. Note for companies: the residency-based route is defined by personal tax residency and is not available to them; only the moderate-rent route can apply, and AT guidance for corporate buyers is still pending. Tax haven entities face an even higher flat rate of 10% with no refund options.
