Italy’s 2026 Tax Benefits: Reduced Rates for Collective Agreement Wage Increases
Italy’s 2026 budget introduces a beneficial tax measure for private sector employees: a reduced income tax rate of 5% on salary increases resulting from national collective bargaining agreement renewals. This change, part of the 2026 Maneuver (Law no. 199/2025), aims to boost worker incomes while carefully considering the impact on existing benefits like the supplementary treatment (formerly known as the Renzi bonus).
Who Benefits from the Reduced Tax Rate?
The 5% reduced tax rate applies to private sector employees who earned up to €33,000 in 2025. However, it’s crucial to understand the specific conditions:
- Eligible Increases: The reduced rate only applies to increases stemming from national collective bargaining agreements (CCNLs) signed between January 1, 2024, and December 31, 2026. Corporate, territorial, or individual agreements are excluded.
- Timing is Key: The “expanded accrual principle” dictates when the increase qualifies. Increases received on or after January 13, 2026, are eligible. Increases paid between January 1st and January 12th, 2026, will be taxed under the 2025 tax rules and won’t benefit from the reduced rate.
How Does This Interact with Supplementary Treatment?
The supplementary treatment is an income integration available to employees earning between €8,500 and €15,000 annually, or up to €28,000 if their IRPEF (income tax) exceeds their deductions. The 2026 budget ensures that the reduced 5% tax rate doesn’t jeopardize eligibility for this bonus.
Here’s how it works:
- Increases subject to the 5% rate are not included in the calculation of overall income for supplementary treatment eligibility.
- However, they are considered when determining income from employment specifically for verifying the right to receive the supplementary treatment.
This mechanism allows workers to maintain their eligibility for the bonus even with a salary increase taxed at the reduced rate.
Important Considerations
- Valid Collective Agreements: Increases must originate from National Collective Labour Agreements signed by nationally representative trade unions. Simply stating “national contract” isn’t sufficient; the signatory parties must be officially recognized.
- No Corporate or Territorial Agreements: The 5% rate doesn’t apply to agreements at the corporate or territorial level.
- Accrual Principle: The expanded accrual principle is critical for determining the correct tax year for the increase.
Why Understanding This Mechanism Matters
Knowing how this reduced rate works and its connection to the supplementary treatment empowers employees to:
- Verify their tax and social security rights.
- Identify and correct any calculation errors on their payslips.
- Maximize their net income increase without risking penalties.
For those receiving increases resulting from CCNL renewals in 2026, this measure offers a lighter tax burden and continued access to the supplementary treatment, leading to a more consistent monthly bonus.
