ISTAT Adjustment
Annual adjustments are tied to the ISTAT consumer price index (FOI):
| Contract Duration | Maximum Adjustment |
|---|---|
| Standard minimum (6 or 9 years) | 75% of ISTAT variation |
| Exceeding the minimum | 100% of ISTAT variation |
The adjustment must be expressly requested in writing and applies from the date of the request, not retroactively.
Large Leases (Annual Rent Exceeding €250,000)
For large leases, parties can agree on:
- Free adjustment mechanisms (100% ISTAT regardless of duration, eurozone inflation, or custom indices)
- No statutory limitations on rent increase structures
Step Rent
A common commercial practice where rent increases incrementally over the lease term (e.g., reduced rent in years 1-2 during business establishment, increasing thereafter). Must be specified in the original contract.
Prohibition on Increase at Renewal
Landlords cannot increase rent at automatic renewal. Increases are only possible at final contract expiry (new contract), following agreed property improvements, or through consensual renegotiation.
Renegotiation
Parties may agree to modify rent during the lease. The agreement must be in writing and registered with the Revenue Agency. Rent reductions may qualify for partial registration tax refunds.
Best Practices for Landlords
- Include a clear ISTAT clause specifying the percentage and procedure
- Request adjustments annually — it is a right that must be actively exercised
- Consider step rent for new businesses to facilitate tenant establishment
- Document all adjustment communications via registered mail or PEC
- Consider renegotiation during economic downturns — better than vacancy
