IRES (Imposta sul Reddito delle Societa) is Italian corporate income tax, charged at a flat 24% on a company's taxable income. It is the Italian equivalent of corporation tax and applies to SpA, Srl, and other corporate entities.

IRAP (Imposta Regionale sulle Attivita Produttive) is a regional production tax. The national standard rate is 3.9%, but regions can raise or lower it by up to 0.92 percentage points. It is calculated on net production value, which differs from IRES taxable income (e.g., labor costs are typically not deductible for IRAP).

Does this calculator handle IRAP regional variations?

This tool uses the standard national IRAP rate of 3.9% for planning purposes. If your company operates in a region with a different rate, adjust manually: the standard rate range runs from 2.98% to 4.82%.

Is IRAP deductible for IRES purposes?

A partial deduction applies: 10% of IRAP paid is deductible from the IRES tax base in certain circumstances (broadly, where labor costs are included in the IRAP base). This tool uses the simplified gross rates; consult a tax advisor for the precise net position.

Are there reduced IRES rates for small companies?

Italy does not have a general reduced IRES rate for SMEs. The 24% rate applies uniformly. Certain special regimes (e.g., for startup innovative companies, patent box regime) can reduce the effective IRES burden — those are not covered by this calculator.

What entities pay IRES and IRAP?

IRES applies to resident companies (SpA, Srl, cooperative societies, etc.) and non-resident companies on Italian-source income. IRAP applies to all entities carrying on business activities in Italy, including partnerships and individuals with business income, using a different base.

Summary

Italian companies are subject to two main corporate taxes: IRES (Imposta sul Reddito delle Societa) at a flat 24% rate on taxable income, and IRAP (Imposta Regionale sulle Attivita Produttive) at a standard 3.9% rate levied on a slightly different net production value base. This calculator uses the same taxable profit figure for both taxes, which is a common simplified approach for planning purposes. The combined effective rate is typically around 27.9%, though IRAP may vary by region (most regions apply the standard 3.9%).
