What it is
The Certificazione Unica is the document by which an employer, pension body or other withholding agent certifies the income paid and the tax withheld during the year. It is needed for the tax return and many other procedures. CUs issued by INPS are available in the personal area of the INPS website.
Who may need it
- Employees and pensioners who need to file a return
- People who received INPS benefits, such as NASpI
