What IMU is and how it works
The IMU (Imposta Municipale Unica) is the property tax in Italy, levied on property ownership. The State sets the general rules and cadastral multipliers, but each municipality sets its own rates every year within the legal limits — which is why the tax on the same home can vary widely from town to town. On TaxDemocracy you’ll find a dedicated page for each of the over 7,936 Italian municipalities.
Who pays and what’s exempt
IMU is paid by whoever owns the property (ownership or another right in rem). The non-luxury first home and its appurtenances are exempt; second homes, luxury properties (A/1, A/8, A/9), land, and building plots are subject to IMU.
Deadlines and how it’s calculated
It is paid in two instalments via the F24 form: down payment by 16 June and balance by 16 December. The taxable base is the cadastral income revalued by 5% and multiplied by the category coefficient; the municipality’s rate is applied to it. The cadastral income is shown on the cadastral survey (Agenzia delle Entrate).
