Clara Cars ISV & IUC Calculator

Add a free Portuguese vehicle-tax calculator to any page or post. Visitors enter engine size, CO₂, fuel and registration year and get an instant estimate of:

• ISV — Imposto Sobre Veículos (one-off import/registration tax)
• IUC — Imposto Único de Circulação (annual road tax)

The figures are a maintained estimate, cross-checked against the official Autoridade Tributária (AT) tables — not the official AT figure and no substitute for the AT simulator or a despachante. The calculation is open source (MIT): https://github.com/claracarspt/calcs Available in Portuguese, English, Russian and Ukrainian. How to use
