IMT and Stamp Duty Calculator
IMT and stamp duty are paid before completion and are among the largest costs of buying. Work out what you will owe.
Result
IMT is progressive. The rate shown is that of the band the property falls into, but it is not charged on the whole value: the "parcela a abater" adjusts the sum so that only the portion above each threshold is taxed at the higher rate. Above certain values a single flat rate applies to the entire amount, with no abatement. These taxes are paid before completion and exclude notary fees, land registry costs and the valuation.
These figures are indicative and not binding. They are the result of an arithmetic calculation on the values you entered and do not constitute a contractual offer, a credit approval, or any guarantee of the terms shown. They exclude fees, taxes, insurance and other charges, and therefore do not represent an APR (TAEG).
