Order No. 471/2025/1 December 26th
The Municipal Property Tax Code (CIMI) establishes that the average construction cost per square metre is one of the elements used in calculating the taxable value of urban properties. This value is set annually, following a proposal from the National Commission for the Evaluation of Urban Properties, after consultation with the entities provided for by law. In accordance with Article 62 of the CIMI, the Government, through the Secretary of State for Tax Affairs, approves the average construction cost to be applied each year.
Accordingly, for the year 2026, the average construction cost per square metre is set at €570.00 for the purposes of valuing urban properties.
This amount applies to all urban properties whose IMI Model 1 declarations are submitted from 1 January 2026 onwards.
