Italian corporate income tax (IRES) — work out the tax due

IRES is a flat tax: 24 % of the company's taxable income. For the single tax period following the one in progress on 31 December 2024 (2025 for a calendar-year company), the rate drops to 20 % if the company sets aside at least 80 % of its 2024 profits, invests part of them in new 4.0 or 5.0 capital goods, raises employment by at least 1 % and meets the other conditions.

Calculation assumptions

  • Taxable income is taken as given: the tool does not derive it from the accounts, and applies no losses carried forward, tax credits or payments on account.
  • The IRES premiale conditions are those you declare; the implementing rules of the ministerial decree of 8 August 2025 are not checked.
  • IRAP (regional tax on productive activities) is not included.
