How Portugal property purchase tax works
When you buy real estate in Portugal, the biggest upfront costs are usually IMT (property transfer tax) and stamp duty. If you use a mortgage, you also pay stamp duty on the financed amount. On top of that, there are practical closing costs such as notary and registry fees.
This calculator combines the most common components so you can estimate your cash needed at closing before making an offer.
Main taxes included in this calculator
- IMT (Imposto Municipal sobre as Transmissões Onerosas): Transfer tax based on price and usage type.
- Stamp Duty on purchase deed: Typically 0.8% of the purchase value.
- Stamp Duty on mortgage: Applied to the loan amount using the term-based rate.
- Notary and registration estimate: Included as a user-editable fixed cost.
IMT rates: primary residence vs second home
IMT is progressive for most residential purchases up to high-value tiers. The tax structure differs between a primary residence and a second home/investment property. Generally, second homes are taxed more heavily at lower price ranges.
What this calculator helps you decide
- How much cash to reserve before signing the deed
- Whether changing mortgage size significantly affects total upfront costs
- The difference in tax impact between primary and investment use
- How sensitive your transaction is to purchase price changes
Example scenario
If you buy a €300,000 property as a second home with a €180,000 mortgage and long-term financing, your total purchase taxes can be several tens of thousands of euros once IMT, deed stamp duty, loan stamp duty, and closing fees are added together.
Testing multiple scenarios with this calculator can help you set a realistic maximum offer price.
Costs not included here
This tool focuses on purchase-side transfer taxes and basic closing fees. Depending on your case, you may also have:
- Lawyer or solicitor fees
- Bank arrangement and valuation fees
- Condominium prorations
- Future annual taxes like IMI (municipal property tax)
- AIMI for higher-value holdings where applicable
Final tip before you buy
Use this estimate early during your search, then confirm final numbers with your lawyer, notary, and lender before completion. Portuguese tax tables are updated periodically, so always verify rates in force for your signing date.
