Request balances and average balances
Banks and the post office issue a document with the balance and average balance of accounts, passbooks and cards.
Add home and vehicles
Cadastral data, registered rental contract, vehicle number plates.
Submit the DSU
With the DSU, INPS calculates the ISEE and issues the certificate.

Frequently asked questions
What if I forget an account?
The certificate may report omissions or discrepancies. In that case the DSU must be corrected: better to check carefully beforehand.
