Italy Thirteenth Salary Calculator (tredicesima and quattordicesima)
Calculate the tredicesima (thirteenth salary) in Italy for 2026: gross amount by months worked, INPS, IRPEF at the marginal rate and the net amount.
Estimate without regional and municipal surcharges. Deductions for employees are spread over the monthly pay, so the tredicesima usually pays tax at the full marginal rate.
What it does
The tredicesima is the thirteenth monthly salary that collective agreements in Italy give every employee, usually paid in December: one twelfth of the monthly gross for each month worked in the year, counting a month from 15 days. Some agreements, such as commerce and tourism, also give a quattordicesima in July, calculated the same way from July to June. It pays INPS contributions and IRPEF like the normal salary.
How to use it
- Type the gross monthly salary.
- Type the months worked and, if you know it, the yearly taxable income.
- Read the gross tredicesima, the deductions and the net amount.
The arithmetic runs in your browser. Nothing you type is sent anywhere and nothing is stored, so you can use these with real numbers.
