IMT: Portugal’s property purchase tax in 2026 — how much and when?

Calculation basis

Start with the taxable amount and the correct purpose

1. 01
   Compare the price and taxable property value

   As a rule, IMT and Portuguese stamp duty (Imposto do Selo) are charged on the higher of the contract price or value and the property’s taxable value.

2. 02
   Define the purpose

   The tables distinguish a main home (habitação própria e permanente) from other housing. Rural land, building land or a non-residential property may use different rates.

3. 03
   Check who is buying

   Reliefs such as IMT Jovem are assessed per buyer and depend on age, tax independence, property ownership history and use of the home.

Practical 2026 IMT table for a main home

Within the progressive bands, multiply the taxable amount by the marginal rate and subtract the stated deduction. There is no deduction in the flat-rate bands.

• Up to €106,346: 0%.
• Over €106,346 up to €145,470: 2%, less €2,126.92.
• Over €145,470 up to €198,347: 5%, less €6,491.02.
• Over €198,347 up to €330,539: 7%, less €10,457.96.
• Over €330,539 up to €660,982: 8%, less €13,763.35.
• Over €660,982 up to €1,150,853: flat rate of 6%.
• Over €1,150,853: flat rate of 7.5%.

Other housing

A second home uses a different table

In mainland Portugal in 2026, the table for housing that is not a main home starts at 1% up to €106,346. It continues with 2%, 5%, 7% and 8% bands, each with its own deductions, up to €633,931. A flat rate of 6% applies from €633,931 to €1,150,853 and 7.5% above that amount.

Do not reuse the main home table for a holiday home, rental or other purpose. The declared classification must match the use and legal conditions of the particular case.

Examples

Always add Stamp Duty and the other costs

For a main home in mainland Portugal with a taxable amount of €250,000, the indicative IMT is €7,042.04: €250,000 × 7% − €10,457.96. Stamp Duty on the acquisition is €2,000: €250,000 × 0.8%. These two taxes total €9,042.04.

At €400,000, also as a main home, indicative IMT is €18,236.65 and Stamp Duty is €3,200, totalling €21,436.65.

• The examples exclude the deed or authentication, registration, bank valuation, fees, insurance and works.
• Where there is credit, use of the loan may also be subject to Stamp Duty.
• A change to the taxable property value, purpose or buyers may change the calculation.

IMT Jovem

Age alone does not guarantee the exemption

In 2026, the mainland table for an eligible young person’s first purchase of a main home provides a 0% rate up to €330,539 and partial taxation in the next band up to €660,982. The scheme also includes a Stamp Duty exemption on the acquisition within the legal limits and conditions.

Among other requirements, the buyer must be no older than 35, must not be a tax dependant and must not own or have owned a property right or partial right over an urban residential property at the time of purchase or during the previous three years. For joint purchases, each buyer’s position should be checked before assessment.

Payment timing

The declaration is submitted before completion

1. 01
   Submit IMT Form 1

   The declaration can be submitted on Portal das Finanças before the final contract, identifying the property, buyers, amounts, purpose and applicable reliefs.

2. 02
   Pay while the assessment remains valid

   The general rule currently provides for payment on the assessment date or within the following 30 days. If the document expires, a new assessment is required.

3. 03
   Bring proof to completion

   On the date of the deed or authenticated private document, proof of IMT and Stamp Duty payment, or proof of exemption, must be presented.
