Keeping an Italian Apartment After Leaving: IMU, TARI, and the Quiet Annual Bill
Keeping an Italian apartment after departure changes the annual bill. IMU loses the prima casa exemption, TARI shifts to non-resident rules, condominio continues.

Plenty of former residents keep the apartment after leaving, intending to come back. What changes the day after the residency ends is the bill. The IMU that was zero on the prima casa is suddenly four figures, and the condominio keeps arriving in inbox 1 of the Italian bank account.
Quick Takeaways
- •IMU on a non-resident-owned apartment typically doubles or triples versus the prima casa exemption
- •TARI continues to be owed based on the comune's occupancy rules for absent owners
- •Condominio ordinary fees continue regardless and are typically the largest single annual line item
- •Renting the apartment generates rental income under cedolare secca at 21% or 26%, or ordinary IRPEF
- •A representative two-bedroom in a mid-sized city sits between three and six thousand euros annually as a non-resident
There is a particular conversation that happens between a former resident and their Italian commercialista in the spring of the year following departure. The conversation is about the annual bill on the apartment that nobody sold. The IMU that was zero on the prima casa for the resident years has reappeared at full rate now that the resident is no longer resident and the apartment is no longer the principal home. The TARI bill arrived in the spring even though the apartment has been empty since November. The condominio statements keep being posted by the amministratore on the same monthly schedule as for the resident owners. None of this is unusual, and none of it was hidden, but it tends not to be visible on the arrival side and tends to surprise on the exit side.
I want to walk through this honestly, because keeping an Italian apartment after departure is a genuinely reasonable choice for many former residents — the property is often a long-term hold, the rental yield in some configurations is meaningful, the option to return is preserved more cheaply by keeping the home than by selling and rebuying. What the choice requires is an honest accounting of the annual cost so the decision is made with the right number in mind, rather than the wrong number that resident owners are accustomed to. This article walks through the IMU mechanics, the TARI mechanics, the condominio mechanics, and the rental-income treatment, with representative numbers from typical Italian apartment configurations.
The IMU Shift the Day After Residency Ends
IMU — the imposta municipale unica — is the municipal property tax that funds the comune's services. For an apartment that is the owner's prima casa, IMU is generally exempt unless the property falls into one of the luxury cadastral categories A/1, A/8, or A/9. For an apartment that is not the prima casa — and a non-resident owner cannot have a prima casa, by definition — IMU is owed at the full rate. The base is the cadastral rent value, revalued by 5% and then by a 160% multiplier for residential properties, and the rate is set by each comune within the range Italian law permits. Most comuni apply the maximum rate to second homes and to non-resident-owned residential property, which is the 10.6 per mille range, sometimes adjusted upward through specific local addizionali.
The arithmetic on a representative two-bedroom apartment in a mid-sized Italian city looks roughly like this. A cadastral rent of seven hundred euros, revalued and multiplied, produces a cadastral value of roughly one hundred seventeen thousand euros for IMU purposes. At the 10.6 per mille rate, the annual IMU is approximately twelve hundred forty euros, payable in two installments — the acconto by June sixteenth and the saldo by December sixteenth. A comparable apartment in a major city center can produce IMU in the eighteen-hundred to twenty-five-hundred-euro range. A genuinely luxury apartment in central Milan or Rome can sit substantially higher.
What does not change in the residency shift is the IMU obligation's owner — IMU is owed by the owner, not by the occupant, and the obligation transfers with the title rather than with the residence. What changes is the rate applied and the exemption status. The owner who lived in the apartment paid little or no IMU for the resident years and now pays the second-home rate for every year of non-resident ownership. The shift is exactly one tax year wide: the resident-rate exemption applies through December thirty-first of the year residency ends if the residency was held for the majority of the year under the standard Article 2 TUIR rules, and the non-resident rate applies from January first of the following year.
The TARI Mechanics for an Empty Apartment
TARI — the tassa sui rifiuti — funds the comune's waste-collection services. It is calculated on the surface area of the property and the number of occupants. For an occupied apartment, TARI is owed by the occupant — whether that is the owner-occupier or a tenant. For an empty apartment owned by a non-resident, TARI is owed by the owner on the basis of presumed minimum occupancy, which most comuni set at one occupant for the assessment. The result is that an empty two-bedroom apartment of approximately ninety square meters generates TARI in the two-hundred-to-four-hundred-euro annual range in most comuni, payable in two to four installments depending on local rules.
The fact that the apartment is genuinely empty does not generally produce an exemption, though some comuni offer a reduction of thirty to fifty percent for properties certified as empty and unfurnished for the full year. Obtaining the reduction requires filing a declaration with the comune's TARI office, typically with photographic evidence and a utility-disconnection record showing no consumption. The reduction is worth pursuing for an apartment that will genuinely remain empty for an extended period; it is not worth pursuing for an apartment that will be used occasionally or kept furnished for future visits.
Renting the apartment transfers the TARI obligation to the tenant for the rental period, with the owner typically managing the comunal interface and recovering the cost through the lease. For short-term rentals through platforms like Airbnb, the TARI obligation generally remains with the owner and is computed on full-occupancy assumptions, which is one of several reasons short-term rental yields are less attractive on a fully-loaded basis than the gross numbers suggest. The interaction with the comunal short-term-rental tax — the imposta di soggiorno levied on guests but collected through the host — is covered in the broader Italian bureaucracy overview.

The Condominio Line That Continues Regardless
If your apartment sits in a condominio — which is almost any apartment in an Italian city — the condominio fees continue exactly as they did during the resident years. The amministratore continues to bill the ordinary monthly quota covering the shared services: building cleaning, elevator maintenance, centralized heating if applicable, ordinary common-area maintenance, the amministratore's own compensation, and the reserve for ordinary repairs. The ordinary quota for a representative two-bedroom apartment in a mid-sized city sits between one hundred fifty and three hundred euros monthly, with substantial variation depending on whether the building has an elevator, centralized heating, doorman service, or shared garden.
Extraordinary expenses — major repairs, façade work, roof renovations, elevator replacements — are voted in assemblea and apportioned among the owners by their millesimi share. These can land at any time and can be substantial: a façade restoration in an older building can produce a per-owner assessment of several thousand euros, payable in installments over twelve to twenty-four months. A non-resident owner is bound by the assemblea decisions in the same way as a resident owner, with the same payment obligation, even if they were unable to attend the meeting where the decision was taken. Granting a procura speciale to a trusted local contact or to the amministratore for the limited purpose of attending and voting in assemblea is the standard solution.
The condominio line is often the largest single annual cost of holding an Italian apartment as a non-resident — typically eighteen hundred to thirty-six hundred euros annually in ordinary fees for the representative two-bedroom, plus the periodic extraordinary assessments. It is also the line that is hardest to reduce, because the costs are largely fixed by the building's configuration and the assemblea's decisions rather than by anything the individual owner can change. The interaction with the partita IVA closure timeline and the bank account that pays these charges is covered in the partita IVA closure deep-dive.
Renting Out the Apartment as a Non-Resident Owner
Renting the apartment after departure converts the cost picture from a pure carrying cost into a yield calculation. Italian rental income earned by a non-resident owner is taxed in Italy on the source basis, with the standard options being the cedolare secca flat regime at twenty-one percent for ordinary residential leases or twenty-six percent for short-term rentals, or the ordinary IRPEF treatment with the income added to other Italian-source income and taxed at the marginal rates. For most non-resident owners with no other Italian-source income, cedolare secca is the simpler and usually the cheaper choice.
The cedolare secca eliminates the registration tax otherwise owed on the lease contract and freezes the rent for the contract duration, which is a constraint on the landlord side but a simplification on the tax side. The twenty-one percent flat rate applies to the gross rental income, with no deduction for the IMU, TARI, condominio, or repair expenses incurred during the year. This makes cedolare attractive for high-yielding configurations and less attractive for low-yielding configurations where the deductible expenses under the ordinary regime would substantially reduce the taxable base. For a typical two-bedroom rented at twelve hundred euros monthly, cedolare produces an annual Italian tax of roughly thirty-two hundred euros, leaving net Italian income before destination-country taxation in the twelve-thousand range.
Destination-country taxation of the same Italian-source rental income depends on the treaty between Italy and the destination. Most modern Italian treaties grant Italy primary taxing rights on real-property income located in Italy and require the destination country to credit the Italian tax paid against any destination tax otherwise due, which usually means the destination tax is reduced to zero or a small residual. The Quadro RW final year deep-dive covers the related question of how Italian and destination-country reporting interact in the year of departure itself, when the rental income spans both resident and non-resident months.
The Annual Math and the Keep-or-Sell Question
Adding the components together for the representative two-bedroom in a mid-sized Italian city: IMU around twelve to fifteen hundred euros, TARI around two to four hundred, condominio around twenty-two hundred, and an annual reserve for ordinary repairs and occasional extraordinary assessments of perhaps eight to twelve hundred. The total carrying cost is in the four-thousand-to-six-thousand range annually for a property that produces no rental income. For a property rented at the representative twelve-hundred-euro monthly figure, the gross income covers the carrying cost with a modest residual margin, and the net economics depend on the cedolare or IRPEF choice and the destination-country treatment.
What the math suggests in practice is that keeping an Italian apartment as a non-resident is reasonable when the property is appreciating, when the rental income at least covers the carrying cost, when the option to return is genuinely valued, or when the apartment is part of a long-term family arrangement. It is rarely reasonable as a pure financial holding for a former resident who has no rental income, no plan to return, and no emotional attachment. Selling the apartment in the year following departure generates Italian capital gains tax only on properties sold within five years of acquisition, and only on the gain above the acquisition cost adjusted for ISTAT inflation — which for most long-held apartments produces a modest or zero Italian tax bill.
The exit costs sub-hub frames the keep-or-sell question alongside the regime impatriati timing and the partita IVA closure timing, because the three decisions often interact. A former resident who held the apartment as prima casa, took regime impatriati, and is contemplating departure within the holding period is making a single coupled decision rather than three independent ones, and the sequencing across them matters meaningfully for the total cost.
The Right Number for the Right Decision
An Italian apartment kept after departure is not free, and the right number for the keep-or-sell decision is not the resident-rate number from the years of living there. It is the non-resident number that begins on January first of the year after residency ends, with IMU at full rate, TARI on minimum-occupancy assumptions, condominio continuing on its existing schedule, and any rental income taxed under the cedolare or IRPEF regime applicable to non-resident owners.
For many former residents the math still favors keeping the apartment, particularly when the rental income covers the carrying cost or when the option to return is genuinely valued. For others the math favors selling, particularly when the apartment is held empty and the carrying cost is a pure annual drag. The decision is reasonable in both directions; what is unreasonable is making it on the resident-rate number rather than the non-resident-rate number that actually applies.
