Overview
- Tax returns in the prefilled 730 became available to view on Thursday, with edits and filing opening May 14 and the deadline set for September 30.
- The tax agency confirmed irregularities in some income certificates and said employers and pension bodies have already sent corrected files that update the prefilled return.
- CGIL said it asked the Economy Ministry on April 21 to order reissued certificates and waive penalties for those who fix mistakes, and it reports no response so far.
- The core flaw is missing or wrong coding of employment income required by law to calculate the new “additional sum” and extra deduction, which the 730 system cannot add back if the CU is wrong.
- INPS said it updated specific fields in its 2026 certificates so excluded income is now recorded correctly, which lets many users accept the prefilled return without extra steps.
