FlatIn.pt
flatin.pt is a digital platform for people buying property in Portugal. Free calculators for purchase taxes, IMI rates for all 308 municipalities, and plain-language guides for foreign buyers — and when you are ready to buy, we connect you with a licensed estate agency.
What we do
Buying property in a country you did not grow up in means facing numbers nobody explains: IMT, stamp duty, IMI, notary and registration fees, NIF, residency. flatin.pt puts those numbers in one place, with the source and the date next to each one.
Tools — free, no sign-up
IMT and stamp duty calculator, built on the official 2026 tables
IMI rates for all 308 Portuguese municipalities, taken from the tax authority's own portal, each with the year it applies to
Full cost-of-purchase breakdown, so the price on the listing is not the last number you see
Guides
Getting a NIF and residency as a foreign buyer. What buying actually costs, taxes included. Written to be read once and understood, not to rank.
Open data
Our municipal tax data is published as CSV, a documented API and an MCP server — free to use, including commercially, with attribution.
When you want to buy
Send a request and a licensed estate agency gets in touch with you. The agency advises you and handles the transaction; flatin.pt is the data and technology layer, not a party to the deal. The agent's work is part of the price of the property, as it always is.
The site is published in seven languages: Portuguese, English, Russian, Ukrainian, German, French and Dutch.
