Compare renting and buying in Italy after taxes — prima casa registration, the 19% mutuo interest credit, bollo on the renter's portfolio, and the 26% / 12.5% capital-gains split for equity ETFs vs government bonds. Both households start with the same liquid wealth; the lower-outflow side invests the difference each month.
How this Italian calculator works
The Italian version assumes prima casa, non-luxury (categoria A/2–A/7), purchased from a private seller — the most common case. One-time costs include 2% imposta di registro on the cadastral value (rendita catastale × coefficient, which you enter directly), €100 in fixed imposta ipotecaria + catastale, notary fees, and real estate agent commission with 22% IVA. Annual buy-side effects include the 19% mutuo interest credit capped at €4,000 of interest paid, while IMU is exempt for prima casa.
The renter's portfolio is taxed at 0.2% bollo annually on its market value, and at realisation Italian rules split the rate: 26% on equity-ETF gains and 12.5% on Italian and EU government bond gains. The simulator tracks cost basis per bucket so the year-end CGT haircut on the renter's net worth reflects the actual mix of equity and bonds in the portfolio.
Inputs cover home price, cadastral value, down payment, mutuo rate and term, notary and agent fees, TARI, and your equity/bond split. See the Methodology page for the worked rules and the year-end math.
