IMT: The Property Transfer Tax Every Portugal Buyer Pays

What IMT is and when you pay it

IMT is triggered by the onerous transfer of real estate located in Portugal — a sale, but also certain share deals in property-holding companies, exchanges, and long-lease assignments. The buyer is the taxpayer. The tax must be settled before the escritura (the public deed of sale): the notary will ask for the DUC payment receipt and will not complete the transaction without it.

Payment is made through the Portal das Finanças or at any tax office. Your lawyer normally generates the assessment a few days before completion, you transfer the amount, and the stamped receipt goes into the completion file.

Rates by property type

The rate depends on what the property is, not on who the buyer is — with one exception covered below. For the commercial and income-producing assets listed on Porameta, the arithmetic is simple: a flat 6.5%.

Residential brackets are revised every January in the state budget. Confirm the current-year brackets on the Portal das Finanças or with your lawyer before relying on a precise figure.

The taxable base: price or VPT, whichever is higher

IMT is charged on the higher of the declared purchase price and the property’s VPT (valor patrimonial tributário — the taxable asset value recorded in the caderneta predial). For most market transactions the price is higher and is the base. But on assets with a recently revalued VPT, or intra-group transfers at conservative prices, the VPT can govern — check it before you model the acquisition costs.

The VPT is stated on the caderneta predial urbana, which any seller can download in minutes. Asking for it early is standard due diligence, and it also tells you the property’s registered use — which matters for the compliance checks covered in our planning guide.

Exemptions and reduced rates worth knowing

Primary-residence buyers benefit from a 0% band at the bottom of the progressive scale, and buyers aged 35 or under have had an enhanced first-home exemption since 2024. These mainly matter to residential purchasers; commercial acquisitions rarely qualify for relief.

Two situations investors should know: properties bought for resale by licensed real-estate trading companies can be exempt if resold within the statutory window, and urban-rehabilitation acquisitions in designated ARU zones may qualify for IMT relief, subject to conditions and municipal confirmation. Both regimes have strict requirements — treat them as a lawyer conversation, not a line in a spreadsheet.

The costs that travel with IMT

Stamp duty (Imposto do Selo) of 0.8% of the same taxable base is paid together with IMT — think of the pair as one bill. If you finance the purchase with a Portuguese mortgage, stamp duty is also due on the loan (0.5%–0.6% depending on term).

After completion, the recurring taxes begin: IMI, the annual municipal property tax, runs at 0.3%–0.45% of VPT for urban property depending on the municipality. AIMI, the additional levy on high-value holdings, applies to residential property and building plots only — commercial and industrial buildings are outside its scope, one of the quiet advantages of income-producing commercial assets.

Worked example: on a €500,000 commercial unit, expect €32,500 of IMT (6.5%) plus €4,000 of stamp duty (0.8%) — €36,500 due before the deed, on top of notary, registration and legal fees.

Rule of thumb for commercial buyers: budget 7.3% of the price for IMT plus stamp duty, then add roughly 1–2% for legal, notary and registration costs.
