Important notice
This simulation uses CIMI rules, applicable ordinances, and cadastral data. When a coefficient cannot be confirmed from an official source, the value from the cadastral record or user input is used.
Results are indicative only and do not constitute tax or legal advice. Differences may arise from legislative changes, administrative decisions, tax benefits, deductions, exemptions, or taxpayer-specific situations. Final validation should be done with the Tax Authority or a qualified professional. The decision to request a revaluation is the sole responsibility of the user.

- Cq base 1.00 + majoratives (garage/pool +0.03 each).
- Cv is based on age: submission year − registration/licence year.
