IMT & Stamp Duty Calculator – Portugal Property Tax Estimator

What is IMT in Portugal?

IMT (Imposto Municipal sobre Transmissões Onerosas de Imóveis) is the Portuguese property transfer tax paid when purchasing real estate in Portugal.

The IMT rate depends on:

• The purchase price of the property
• The type of property (main residence or secondary property)
• Whether the buyer qualifies for an IMT exemption

For a main residence, IMT rates typically range from 2% to 8%, with higher rates applied to more expensive properties.

What is Stamp Duty on Property in Portugal?

Stamp Duty (Imposto do Selo) is a mandatory tax equal to 0.8% of the purchase price.

It is payable at the time of the deed signing and applies to almost all property transactions in Portugal, unless an exemption applies.

IMT Exemptions for First-Time Buyers Under 35

Portugal offers a tax exemption for young buyers aged 18 to 35 who are purchasing their first main residence, subject to specific conditions.

Full IMT & Stamp Duty Exemption

You may benefit from a full exemption if:

• You are 35 years old or younger

• You are purchasing your first main residence

• The property price is up to €330,539

Partial IMT & Stamp Duty Exemption

You may benefit from a partial exemption if:

• You are eligible as a young buyer

• The property price is between €330,539 and €660,982

In this case, IMT and Stamp Duty are only calculated on the amount above the exemption threshold.

No Exemption

If the property price is above €660,982, the exemption does not apply.
