flatin.pt

Two shortcodes for sites that write about buying property in Portugal.

• [flatin_imt value="250000"] — what a purchase costs on top of the price: IMT, stamp duty and the price of registering the purchase.
• [flatin_imi concelho="porto"] — the yearly property tax (IMI) rate for a municipality, with the tax year next to it.

Rendered on your server, into your page. No iframes and no client-side drawing: the output is part of your HTML, so it is styled by your theme, readable without JavaScript, and visible to search engines. Where the numbers come from. IMT is calculated from the official 2026 tables. IMI rates were harvested from the Autoridade Tributária portal and then verified line by line against that same source — all 308 municipalities. Where a municipality sets no single rate (it sets one per freguesia instead), the plugin says so rather than printing a zero. The registration line is not a guess either: it is the published price of the Casa Pronta counter of the Ministério da Justiça for one registration act. It does not cover the purchase contract at a notary or a solicitador, and the shortcode says so under the table. Shortcode options

• [flatin_imt value="250000" territory="regioes_autonomas"] — the Azores or Madeira scale (default: continente, mainland Portugal).
• [flatin_imt value="250000" primary="no"] — not the buyer's own permanent home (default: yes).
• [flatin_imt value="250000" young="yes"] — the reduced IMT table and the stamp duty deduction for buyers aged 35 or under buying their first own permanent home (default: no).
• [flatin_imt value="250000" vpt="180000"] — the VPT (valor patrimonial tributário) from the caderneta predial, if known. IMT and stamp duty are charged on the higher of the contract price and the VPT, and the answer says which one it used.
• [flatin_imi concelho="porto" vpt="180000"] — also shows the yearly IMI for that taxable value (VPT). concelho takes a name or the four-digit code.

Credit link The credit link is off by default. If you would like to credit the source, switch it on in Settings → flatin.pt: results then show a small "Calculated by flatin.pt" line with a link. While it is off, the plugin adds no link to flatin.pt anywhere in your pages — not even when the service is unreachable — and the calculators work exactly the same either way. Who we are flatin.pt publishes open data and calculators on property in Portugal and is a licensed estate agency (AMI licence no. 28163) that answers buyers' requests itself. The results are estimates from official tables, not tax advice. This plugin sells nothing and collects nothing.

1.0.3

• Translations are no longer bundled; WordPress loads them from translate.wordpress.org.

1.0.2

• New vpt attribute for [flatin_imt]. IMT and stamp duty are charged on the higher of the contract price and the VPT; the table now says which one it was calculated on, and without a VPT says that a higher VPT would raise both taxes.
• The Casa Pronta amounts in the note under the table come with the answer from flatin.pt instead of being written into the plugin.

1.0.1

• The third line of the purchase table is named for what the figure actually is: the published price of registering the purchase at the Casa Pronta counter, not an estimate for the deed. The note under the table now names that source, says the contract at a notary or a solicitador is charged separately, and warns that buying with a mortgage costs more.

1.0.0

• First release: [flatin_imt] and [flatin_imi], server-side rendering, transient caching, Portuguese translation, opt-in credit link (off by default).
