Calculate Renovation Bonus (cross-border guide)

The renovation bonus calculator helps cross-border workers who own property in Italy estimate the net cost of home improvement works after applying Italian fiscal incentives: the 50% renovation deduction (Bonus Ristrutturazione), the 65% Ecobonus for energy efficiency upgrades, the Superbonus for qualifying thermal envelope improvements, and the 36% furniture bonus for new appliances purchased after renovation.

The tool calculates the deduction spread (the bonus is recovered over 10 equal annual IRPEF deductions), the total fiscal saving over the full recovery period, and the effective net cost of the works. It accounts for the EUR 10,000 franchise applicable to new cross-border workers under the 2026 Agreement when calculating how much of the Italian tax liability can absorb the deduction.

For cross-border workers, coordination between Swiss withholding tax paid and Italian IRPEF is critical: the deduction is only valuable if you have Italian tax liability to offset. The calculator shows the breakeven point and recommends whether maximising the deduction is optimal or whether alternative investments offer better after-tax returns given your specific Swiss-Italian tax position.

Eligibility for the Bonus Ristrutturazione 2026 requires the property to be located in Italy and used as a primary or secondary residence. Qualifying works include structural renovations, seismic upgrades, bathroom and kitchen refurbishment, electrical and plumbing overhauls, and energy efficiency improvements. The maximum deductible expenditure is EUR 96,000 per property unit, yielding a maximum 50% deduction of EUR 48,000 spread over 10 years. Cross-border workers must retain all invoices showing traceable bank payments (bonifico parlante).

Cross-border workers claim renovation deductions through their Italian tax return (Modello 730 or Redditi PF), specifically in Section III-A for building renovation expenses. The deduction offsets IRPEF liability — but under the 2026 New Agreement, new frontalieri benefit from only a partial Italian tax base due to the EUR 10,000 franchise, which may limit the deductible amount. Workers should verify their projected Italian tax liability before committing to large renovation expenditures to ensure the full deduction can be absorbed over the 10-year recovery period.
