Tax form F24 (ital.: Modello F24)

Question

Accepted Answer

The F24 tax form in Italy is the standardised, summary payment form used to pay almost all important taxes, social security contributions and other levies to the state, regions, municipalities and social security institutions. Anyone who is economically active in Italy – whether as an entrepreneur, freelancer, employer or private individual – can hardly avoid using the F24 payment form.

For entrepreneurs and freelancers, the F24 payment form is used in particular to pay value added tax (VAT), income tax (IRPEF), corporation tax (IRES), regional value added tax (IRAP) and various substitute taxes. Employers use it to pay the withheld wage tax (IRPEF) and social security contributions to the welfare institution INPS/NISF and accident insurance contributions to the accident insurance office INAIL. Private individuals also use the F24 payment form, for example to pay property tax (IMU/GIS) or to settle instalments from tax assessments.

What is the F24 tax form?

The F24 tax form is a standardised payment form. It is used to combine payments to various public authorities and clearly assign them to a specific tax or levy.

A particularly practical feature of the F24 is that it allows several taxes and contributions to be paid in a single transaction. For example, wage tax, INPS contributions, VAT and property tax can all be paid at the same time on a single maturity, expiration date – provided that the tax code, reference year and amounts are entered correctly.

The F24 form is therefore a central instrument in the Italian tax and levy system, comparable to a collective payment receipt for different types of taxes.

What is the F24 form used for?

The F24 is used to process almost all relevant payments to the state, regions, municipalities and social security institutions. These include in particular:

State taxes

Income tax for natural persons (Italian: IRPEF)
Corporation tax (Italian: IRES)
Regional value added tax (Italian: IRAP)

Instalment payments from tax assessments or settlements
Other subsequent payment obligations to the tax authorities

Central importance of the F24 in the Italian tax system

The F24 form plays a central role for several reasons:

a) Uniform form for all
All taxable individuals use the same form – from private property owners to multinational companies. This ensures structured processes, facilitates processing by banks and authorities, and reduces formal errors.

b) Offsetting tax credits
A particular advantage is that tax credits can be offset directly in the form against taxes and contributions that have reached their maturity or expiration date. Examples:

Value added tax credits
Income or corporation tax credits
Credits from social security contributions

This function improves liquidity and reduces bureaucratic effort.

c) Electronic submission (telematic transmission)
Companies and freelancers with a VAT number (Italian: partita IVA) must generally submit their F24 payments electronically, for example via:

the revenue agency's online services or
the bank's online banking service

This facilitates payment allocation, reduces data entry errors and enables better traceability.

Private individuals without a VAT number can still make certain payments in paper form at the bank or post office, but are increasingly using online banking or Chartered Accountants.

It should be noted that not all Italian banks support the electronic transmission of the F24 form, which may lead to difficulties in some cases (often at branches of major international banks).

Types of F24 tax form

In practice, there are several different types:

F24 ordinario (standard form): The "classic" F24 payment form for the state, regions, municipalities and many contributions. It also allows tax credits to be offset against tax liabilities.
F24 semplificato (simplified form): A simplified, usually one-page version, especially for local taxes such as IMU and other municipal taxes.
F24 "Elide" – with identification features (Elementi identificativi): Used when additional information is required, e.g. contract numbers, identification of a specific rental or leasing agreement or a property.
F24 Accise (for excise duties): Special variant for excise duties on energy products, alcohol, etc.

Maturity dates

As the F24 tax form is used for a wide range of taxes and contributions, there are different due dates. As a general rule:

Monthly maturity dates

Many taxes and contributions paid via F24 have their maturity on the 16th of the following month.

Monthly VAT payments
Wage tax and withholding tax on fees
Social security contributions to the pension and social security fund (INPS)

Quarterly maturity dates

VAT payments generally mature on the 16th of the second month after the end of the quarter (16 May, 16 August, 16 November).

Annual maturity dates

Income tax: 30 June (balance and 1st advance payment) & 30 November (2nd advance payment)
Corporation tax and regional value added tax: same dates
Property tax: 16 June and 16 December

If the 16th falls on a Saturday, Sunday or public holiday, the deadline is postponed to the next working day.

Common tax codes (selection)

Each tax or levy has its own tax code. The complete list of these codes is continuously updated by the tax authorities and is very extensive.

The form is divided into different sections. Below is a description of these sections, as well as the most frequently used codes (*).

Frequently asked questions (FAQ)

1. What is the F24 tax form used for?
In Italy, the F24 is used to process almost all important payments to the state and other public authorities: taxes (e.g. income tax IRPEF, corporation tax IRES, regional value added tax IRAP, VAT), social security contributions (INPS/NISF), accident insurance (INAIL), property tax IMU/GIS and numerous municipal and regional taxes.

2. How is the F24 tax form structured?
The F24 form comprises:

a header section with the taxable person's details (tax number, VAT number if applicable, name/company name, address),
a section for bank details and payment method, and
several sections for the state, social security, regions, municipalities and other institutions.

The individual lines use tax codes, reference years and amounts to identify the respective taxes and contributions precisely. This allows multiple payments to be combined in a single form.

3. Who has to submit the F24 electronically?
Entrepreneurs and freelancers with a VAT number must always submit their F24 payments electronically (telematically) via the revenue agency or bank. Private individuals without a VAT number are only required to submit electronically in certain cases, for example when tax credits are offset or certain tax codes are used.

4. When is the F24 due?
Monthly payments via F24 are due on the 16th day of the following month (e.g. wage tax and social security contributions for October → 16 November). Quarterly VAT payments are usually due on the 16th of the second month after the end of the quarter. If the maturity date falls on a weekend or public holiday, the maturity date is postponed to the next working day.

5. What happens in the event of late payment?
Late payments are subject to penalties and interest on arrears. In many cases, missed payments can be made up for via the "voluntary late payment" system, whereby penalties can be reduced if the correction is made early.

6. Can tax credits be offset against the F24?
Yes. Offsetting tax credits against taxes due is one of the main advantages of the F24. However, this requires correct entries and, if necessary, certain notifications to the revenue agency.

7. Can a submitted F24 form be corrected?
If an F24 form is submitted with errors (e.g. incorrect tax code or incorrect reference year), it is not usually possible to simply cancel it. Corrections are made via an official procedure at the revenue agency and should ideally be carried out with the assistance of a tax specialist.
