IMU: the property tax nobody bills you for

IMU (Imposta Municipale Unica) is the municipal tax on property ownership. For a foreign owner, an Italian holiday home is by definition a second home — so IMU is due every year, in two instalments, whether or not the property is rented.

The trap: Italy sends no bill

Unlike council tax in the UK or property tax in the US, IMU is self-assessed. The municipality does not send an invoice; the owner is expected to know the tax exists, calculate it, and pay it by 16 June (advance) and 16 December (balance). This is why so many foreign owners first hear of IMU years after buying — through an assessment notice with penalties and interest attached.

How it is calculated

The base is the rendita catastale — the cadastral income shown on your purchase deed or a visura catastale. The formula:

Example: a rendita of €900 gives a taxable value of €151,200; at the common 1.06% rate, IMU is about €1,600 a year. Every municipality sets its own rate and can differentiate — some apply reduced rates to registered agreed-rate contracts, and IMU is reduced by 25% for canone concordato lettings by national law.

Paying from abroad

IMU is paid with an F24 form using the municipality's codes. Owners without an Italian bank account can pay via bank transfer under specific instructions, but the F24 route through an Italian intermediary is cleaner and leaves the audit trail you want. Our subscription includes the calculation and ready-to-pay F24 forms before both deadlines, plus a check of your municipality's current resolution — rates change more often than owners expect.

Arrears: fixable, and better fixed early

Unpaid past years can be regularised voluntarily through ravvedimento operoso at reduced penalties, provided the municipality has not yet assessed them. Five years of quiet arrears handled proactively cost a fraction of the same years surfacing in an enforcement notice.
