How to calculate IMT in Portugal
IMT follows a clear formula: taxable value × bracket rate − deduction. The applicable table depends on region, property type and buyer profile.
1. Determine the taxable value
Use the higher of the purchase price and the property’s official VPT, under CIMT article 12.
2. Select the correct table
Choose mainland or islands, main home or second home, and the resident, non-resident or eligible young-buyer regime.
3. Apply the bracket
For progressive tables, calculate IMT as taxable value × rate − deduction. The deduction incorporates the lower brackets.
4. Add Stamp Duty
Purchase Stamp Duty is generally 0.8% of the same taxable value. Mortgage finance may attract a separate duty.
