It is worth over EUR 57 billion a year. It is paid by 1.3 million companies and entities. Its rate is 24 per cent, but can be reduced to 20 per cent. It is the IRES, the tax for which the ministerial decree signed on 8 August 2025 regulates the 'premium' version (i.e., with a rate of 20 per cent), reserved for companies that invest in production and hire new staff. But let us go in order.

What is IRES?

.

IRES is the tax paid by corporations and entities (it is regulated by article 73 of the Tuir). It provides for only one proportional tax rate, which is 24 per cent and is levied on business income.

Who has to pay IRES?

.

According to the Finance Statistics, of the approximately 1.3 million taxpayers who pay it, 1.2 million are limited liability companies (Srl). In addition to LLCs, this tax has to be paid by joint-stock companies (S.p.A.) and other corporations (such as limited partnerships).

Cooperatives and mutual insurance companies are also required to pay it. Public and private entities, consortia, trusts, undertakings for collective investment (OICR) and non-commercial entities (non-profit organisations) must also pay IRES. Among the taxpayers, for example, are 473 foundations.

Why is it in the news?

The Budget Law for 2025 provides for a discount on IRES in favour of companies that leave a significant portion of their profits in the company, in order to allocate them to investments, new hires, welfare or training. The reduced rate is 20 per cent (instead of 24 per cent).

The implementation of the premium IRES was long overdue by companies, especially after the abolition from 2024 of Ace, the incentive that rewarded company recapitalisations.

Is it correct to say that IRES is a flat tax?

Yes, IRES is a proportional tax and is therefore applied at the same percentage regardless of the amount of income. It is one of the many flat taxes in the Italian system.

How much is IRES worth to the State?

In 2023, IRES brought EUR 51.8 billion into the public coffers, an increase of EUR 6.1 billion (+13.3% year-on-year), a figure that rose to EUR 57.6 billion in 2024, with another increase of EUR 5.8 billion (+11.3%). The 2025 revenue is also doing well: the latest Tax Revenue Bulletin shows that between January and June of this year, 17 billion has already arrived in the public coffers, more than twice as much as last year, but the comparison is not reliable in this case, because in 2024 30 June (the ordinary deadline for self-assessments) fell on a Sunday, so the payments flowed into July.

The good trend in IRES revenue is linked to the improvement in company accounts, but also to the disappearance of last years' concessions, starting with Ace.

As a comparison to the relative weight of other taxes, last year 180.7 billion came from VAT and 235.6 billion from Irpef (the personal tax paid by employees, pensioners, entrepreneurs, and the self-employed who do not apply the flat-rate regime). The Irap, the other major tax paid by businesses, brings in around 33 billion a year for the Treasury, taking into account the share paid by private individuals and that paid by public bodies.

How has the IRES rate changed over time?

The current IRES is the heir to the Irpeg, which previously had a rate of 36 per cent. Until 2016, the IRPEG rate was 27.5 per cent, then it was reduced to 24 per cent.

What does IRES apply to? What about mini-Ires?

Companies and commercial entities pay corporate income tax. This is determined by starting from the profit (or loss) shown in the statutory financial statements prepared by the company or entity and adjusting it by applying the changes or decreases provided for in the tax legislation. Entities that are not resident in Italy pay IRES only on income generated in Italy. The mini-Ires (or bonus Ires) applies to Ires entities that have set aside at least 80 per cent of their profits in 2024 and have allocated part of them to investment in capital goods, guaranteeing an increase in employment in 2025.
