It must be delivered to workers every year and is also sent to the Revenue Agency which uses the form as the basis for preparing the pre-compiled tax return.
Employers give it to their employees and INPS does the same thing to pensioners and recipients of other benefits.
For the employer, withholding agent, the electronic sending of the CU form is mandatory.
In 2024, the submission for employees and pensioners must be done by March 16 (and the submission to the Revenue Agency must be made by the same date).
For the sums paid to self-employed workers, the electronic transmission can be carried out within the same deadline as the 770 form.
Based on article 16 of the Simplifications decree from 2025, the 770 form should be archived.

However, it is underlined that this obligation ceases starting from the 2024 tax year, this implies that it must still be prepared for the 2023 tax year.
It follows that those who have joined the flat-rate regime, or other advantageous regime, must send the CU relating to the entitlements paid in 2023 by 16 March 2024.
Article 3 of the Fiscal Simplifications decree applies both to the sending of the CU to Revenue Agency, and to the sending to the recipients.

With Resolution no.
55 of 3 October 2023, the Revenue Agency provided the necessary information to correctly fill out this section in 2024.
However, the information provided was partly superseded by Note 386245 of 27 October 2023 from the Revenue Agency.
The general rule is that the children's personal data must be indicated in the Single Certification in the event that the parent must claim tax deductions or deductions.
However, the Note specifies that the withholding agent is not required to indicate the data (tax code) of the dependent children for whom the Single Allowance is received.
However, there are exceptions to this general rule and they are: employee who, during the tax adjustment, asks the tax withholding agent to recognize deductions for expenses for children; presence of concessions in the calculation of regional surtaxes; in the presence of company benefits and services recognized to employees in favor of their children and which do not contribute to the determination of income (for example courses), within the non-taxable limit of 3,000 euros; when the employee requests recognition of deductions for dependent children (over the age of 21).

The new rules came into force on 1 July 2023, it follows that there will be a double regime for the tax year just ended: the compensation received by sports workers until 30 June 2023 is considered "other income"; those received from 1 July to 31 December are, however, considered "income from employment and similar".
It follows that for income received starting from 1 July the deductions and deductions foreseen for this type of compensation must also be applied, obviously pro rata.
For other incomes, earned from 1 January 2023 to 30 June 2023, no deduction is foreseen.
Taxation of tips There is also news in relation to the new taxation of tips for the tourism sector.
Starting from 1 January 2023 (2023 budget law), the new regulation on the taxation of tips in the tourism sector will apply.
The legislation provides that donations made to workers in the tourism sector are subject to substitute taxation at a rate of 5%.
In order for the substitute taxation to apply, the worker, employed in the private sector, must not have received income exceeding 50,000 euros in the previous year.
There is also a further limit: the preferential taxation can be applied within the limit of 25% of the income received in the year for the related work services.
The worker can also expressly waive this substitute taxation by communicating this to the employer.
In the instructions issued by the Revenue Agency it is specified that: in point 651 the amount of 25% of the income received must be indicated; in point 652 the amount of tips subject to substitute taxation must be reported; in point 653 the amount of the substitute tax applied on the sums paid by customers to workers as donations must be reported.
Fringe benefit taxation Among the advantages recognized to workers with children is the raising of the threshold of fringe benefits not subject to taxation.
In this case the Revenue Agency's instructions indicate that these amounts must be indicated in point 475 of the CU2024 form.
Amounts exceeding 3,000 euros as fringe benefits are fully taxed according to ordinary rules and contribute to the formation of the tax base.
Field 475 must also indicate the value of the fuel bonuses granted during the employment relationship, regardless of their amount.
