Tax Calculators
Simple, free tools to estimate everyday taxes in Portugal: from vehicle tax to capital gains.
IRS Calculator (Portuguese Income Tax)
How much IRS do you pay on your income? This calculator applies the 2026 IRS brackets (mainland Portugal) to your taxable income and shows the tax (coleta), your effective average rate and the bracket you fall into. Choose individual or joint taxation (the family quotient) and see, step by step, how the tax is reached.
Open calculator →IVA Calculator (Portuguese VAT)
Want to know how much VAT (IVA) is in a price, or what something costs without VAT? This calculator adds or removes Portuguese VAT from the amount you enter, at the rate you choose (standard, intermediate or reduced) and for your region. See the net amount, the VAT and the gross amount side by side.
Open calculator →IMT Calculator (Portuguese Property Transfer Tax)
How much IMT will you pay when buying a home? This calculator estimates Portugal’s property transfer tax (IMT) from the deed price (or the VPT, if higher) and what the property is for: own permanent home, second home, land or other building. See the amount, the rate applied and how it is reached.
Open calculator →IMT Jovem Calculator (young buyers’ tax exemption)
Are you under 35 and buying your first home in Portugal? IMT Jovem exempts you from both the IMT (property transfer tax) and the acquisition Stamp Duty. This calculator shows how much you save: the exemption is full up to €330,539, partial between that and €660,982, and disappears above it. Enter the purchase value (or the VPT, if higher) to see the saving.
Open calculator →Stamp Duty Calculator (Portuguese Imposto do Selo)
How much Stamp Duty (Imposto do Selo) do you pay when buying a home in Portugal? You pay it twice: 0.8% on the purchase value and, if you take a mortgage, 0.5%–0.6% on the loan amount. This calculator estimates both parts and the total, from the deed price (or the VPT, if higher) and the credit.
Open calculator →IMI Calculator (Portuguese Property Tax)
How much IMI will you pay this year? This calculator estimates Portugal's annual municipal property tax (IMI) from your property's taxable value (VPT) and your municipality's rate, applying the family deduction where relevant. See the amount, the number of instalments and how it is reached.
Open calculator →IUC Calculator (Portuguese Road Tax)
How much IUC will you pay this year? This calculator estimates Portugal's annual vehicle circulation tax (IUC) for Category B light passenger cars (first registered from July 2007), based on engine displacement, CO₂ emissions, the year of first registration and the fuel. See the amount and how it is reached, component by component.
Open calculator →ISV Calculator (Portuguese Vehicle Tax)
How much ISV will you pay when registering a car? This calculator estimates Portugal's one-off vehicle tax (ISV) for light passenger cars (Table A) from engine displacement, CO₂ emissions (WLTP) and fuel, with a reduction for used imported vehicles. See the amount and how it is reached, component by component.
Open calculator →Capital Gains Tax Calculator
Sold shares, ETFs or funds at a profit? Work out the capital gain and the IRS tax due: the autonomous rate is 28% on the gain. Enter the purchase value, the sale value and your costs to see, in seconds, how much you keep after tax.
Open calculator →Late-Payment Interest Calculator (Portuguese Juros de Mora)
How much late-payment interest (juros de mora) can you charge, or do you owe, on an overdue payment? It is simple interest on the amount owed, counted by the days of delay. Enter the amount, the rate that applies to your case (4% for civil debts, around 10% for commercial ones) and the number of days late, and this calculator estimates the interest and the total to pay.
