IMT and Stamp Duty Exemption Regime
Acquiring a property in Portugal may allow access to several tax benefits. Because thresholds and rules can change, it is important to validate your eligibility and the applicable table for your specific case.
For the general tax framework, you can also read what IMT is and when it is due. If you already want a quick estimate, use the Portugal IMT calculator.
🆕 Youth Regime (Up to 35 years old) — Primary Residence (HPP)
The “IMT Jovem” regime may provide substantial savings when purchasing a permanent home (HPP), subject to legal requirements:
- Full exemption (Mainland Portugal): up to €330,539.
- Full exemption (Autonomous Regions – Azores/Madeira): up to €413,174.
- Above these amounts: partial exemption may apply, with IMT on the excess under the relevant brackets.
- Eligibility: conditions apply (age ≤35 and other legal criteria).
* Values aligned with the official practical tables in force from 01-01-2026.
🏠 General Exemption — Primary Residence (HPP)
Regardless of age, full IMT exemption may apply for HPP when the taxable value does not exceed the exemption threshold:

- Autonomous Regions: up to €132,933.
* Applicable when the purchase meets the legal conditions for HPP.
⚖️ When legal support makes sense
Correctly applying tax benefits at the deed is critical. A classification or eligibility error can lead to unnecessary tax payments, delays, and avoidable corrections.

Legal review of your profile and the property details to confirm the applicable exemption regime.

Assessment and support if IMT was incorrectly charged (when legally possible).

👥 Regional specifics and common cases
🌍 Foreign residents
Eligibility may depend on how the property is classified and the documents presented. We recommend validating your case.
👫 Couples (mixed eligibility)
If only one party meets a requirement (e.g., age), eligibility may vary depending on the regime and ownership share.
🏝️ Azores and Madeira
Autonomous Regions apply different thresholds according to the regional tables.
After reviewing the available reliefs, it helps to compare them with a quick estimate on the calculator and the broader IMT guide. If your purchase is already moving towards completion, you can also use the practical guide for the steps around Modelo 1 and the payment documents.
