Fisco, Cgil alarm: 730 at risk for errors on incomes. The Inland Revenue: pre-filled forms already updated
The union Cafes denounce the presence of errors in the calculation of the new tax wedge cut. The Agency: in the case of rectifying single certifications issued by the substitutes, taxpayers will be informed by personalised notices

Key points
The alarm comes from the CGIL twenty-four hours after the debut of the precompiled 2026: at risk the 730 for errors in the unique certifications. But the financial administration's reply circumscribes the impact of the complaint. According to the Inland Revenue, in fact, 'some tax substitutes (employers or pension bodies) in recent weeks have detected anomalies in the single certifications (Cu) prepared by them and have immediately corrected and re-transmitted them. Therefore, the 2026 pre-filled declaration has already been updated with the new data received'.
Consultation only until 14 May
The Agency recalls that 'until 14 May, the 2026 Precompilata will only be available for viewing, and in the event that any withholding agent realises that it has made errors in the CICs issued, the same withholding agent will have to send the Agency an amending certificate'.
Customised notice in case of single rectification certification
In addition, the Revenue emphasise that 'the taxpayers concerned will be informed of the presence of the amended Single Tax Certificate in their tax drawer with a personalised notice visible on the web page of the pre-filled declaration'
The case raised by CGIL
According to the CGIL, which had sent a letter on 21 April to the Minister of the Economy Giancarlo Giorgetti and the Deputy Minister of the Economy Maurizio Leo, 'it has emerged how a significant number of tax substitutes have issued employees with Single Certifications 2026 in which incorrect or absent data on the nature of employment income (Article 49, paragraph 1, of the Tuir) are shown, useful for verifying the right to the sum that does not contribute to the formation of income ('additional sum') or to further deduction for employment income'. In practice, errors were allegedly made by tax withholding agents in indicating the new items characterising the cut in the tax wedge applied from 2025.
CAP monitoring
The confederal secretary of the CGIL, Christian Ferrari, and the president of the Caaf CGIL national consortium, Monica Iviglia, had explained that that letter had not yet been followed up with a reply and the problem risked having a effect on the pre-filled 730s that will be made available from the afternoon of 30 April on the reserved area of the Inland Revenue website. The errors in the Single Certifications emerged through the constant monitoring of the organisation's territorial structures and its Tax Assistance Centres.
