About

Calculate ISV and IUC taxes for importing cars to Portugal. Automatically detects vehicle specifications from European car listing sites.                                                 

What it calculates
  • ISV (Imposto Sobre Veículos) — the one-time vehicle registration tax
  • IUC (Imposto Único de Circulação) — the annual road tax

Supported car listing sites
  • AutoScout24 (all European country domains)
  • mobile.de
  • leboncoin.fr
  • coches.net

How it works
  1. Browse any car listing on a supported site
  2. A floating widget appears with the ISV and IUC breakdown — no clicks needed
  3. The extension automatically reads the vehicle specs from the page (fuel type, engine displacement, CO₂ emissions, registration date)
  4. If any specs are missing from the listing, it looks them up automatically using public vehicle databases

Open the pop-up calculator from the toolbar to manually enter vehicle details and calculate taxes for any car.
