As of 2025, the so-called “Solidarity Contribution” is now in effect—a new tax designed to strengthen the pension system. As we explained in our September 2024 post, “Solidarity Contribution: What it is and who it affects”, this measure applies an extra Social Security contribution to high earners whose salaries exceed a set threshold. The rate is progressive, increasing with income, and the cost is shared between employees and employers.
The main goal of this initiative is to ensure the long-term sustainability of the pension system, especially as the aging population continues to put pressure on social protection programs. By implementing this measure, the government aims to secure the necessary resources to maintain financial stability and balance over time.
Starting January 1, 2025, employees earning above the maximum contribution base—set at €4,909.50 per month for 2025—will be subject to this additional solidarity contribution.
The cost of this contribution will be shared between employees and employers. Below is a breakdown of the 2025 contribution rates by income bracket:
