Belgium’s Pension Reform: How Raising Retirement Age Cuts Costs—and Who Pays the Price

The Belgian government’s 2025 pension reform—raising the legal retirement age—has already saved €632 million in public spending. But the long-term impact on retirees’ incomes, inequality, and fairness between sectors is far from settled. Here’s what the data shows.

€632 Million Saved in 2025, But at What Cost?

The Belgian state reported €632 million in savings in 2025 alone from the gradual increase in the legal retirement age, part of a broader pension reform aimed at sustaining the system amid demographic pressures. According to Le Soir, total legal pension spending in 2024 exceeded €66 billion—nearly a quarter of Belgium’s total social expenditure.

Yet the savings come with trade-offs. By 2070, the reform will reduce the replacement rate—the percentage of a worker’s final salary paid as a pension—by 15% for civil servants, 7% for private-sector employees, and 3% for self-employed individuals. This targeted approach reflects a deliberate policy to narrow disparities between pension regimes, but it also risks deepening inequality among retirees.

Why Are Civil Servants Hit Harder?

The reform’s most controversial feature is its differential impact on civil servants. Historically, Belgian public-sector pensions have been more generous, with higher replacement rates and additional benefits like second-pillar pensions (employer-sponsored schemes). However, as the Bureau du Plan’s analysis highlights, these advantages are often overstated:

• Second-pillar pensions are minimal: For over half of private-sector employees, these schemes add just €28 per month to their pensions.
• Perks over pensions: Many public-sector workers benefit more from tax-free allowances (e.g., company cars, meal vouchers) than from formal pension supplements.
• Indexation caps: Pensions exceeding €2,000/month will now be partially frozen during inflation periods. A €3,000 pension, for example, would gain only €200 (not €300) under 10% inflation—a rule that disproportionately affects civil servants.

“The goal is to achieve ‘convergence’ between regimes,” explains Maxime Fontaine, a public finance researcher at the Université Libre de Bruxelles (ULB). “But convergence doesn’t mean equality—it means aligning downward.”

Inequality Worsens: The Poorest Retirees Lose Out

While the reform trims costs, it also widens the gap between high and low pensions. Two key measures are driving this:

1. End of the “Bien-être” fund: This fund previously ensured periodic revaluations for the lowest pensions. Its abolition means the poorest 10% of retirees will see their pensions stagnate relative to higher earners.
2. Limited indexation: Only the portion of a pension up to €2,000/month is fully indexed to inflation. The rest is frozen, benefiting those with larger pensions more.

Data from the Bureau du Plan shows that by 2035, the gap between the top 10% and bottom 10% of pensions will grow by 12% compared to pre-reform projections. Critics argue this contradicts the government’s stated aim of reducing inequality.

“The reform was sold as gender-neutral, but women—who earn less on average and rely more on public pensions—will bear the brunt,” notes pension advocate Sacha Daout of the Confédération Nationale des Travailleurs (CNT). “Yet the data shows the opposite: inequality rises, and women’s pensions shrink faster.”

Healthcare Costs Rise While Pensions Shrink

Even as the state saves on pensions, healthcare spending is projected to surge. The Royal Institute for the Equalization of Healthcare Reimbursements (RIZIV) warns that real healthcare costs under the sickness and invalidity insurance scheme will rise by €10.9 billion (2.6% annually) by 2035—outpacing pension savings and straining the social budget.

This tension highlights a broader challenge: Belgium’s aging population demands more from both pension and healthcare systems, but reform efforts are fragmented. While raising the retirement age eases short-term pension pressure, it does little to address the long-term funding gap in healthcare, which now accounts for nearly 12% of GDP.

Key Takeaways: What This Means for Retirees

• Civil servants face the steepest cuts—their replacement rates drop by 15%, more than double the private-sector reduction.
• Inequality grows: The gap between high and low pensions widens due to frozen indexation and the end of targeted revaluations for the poorest.
• Women lose disproportionately, as their lower earnings and reliance on public pensions leave them vulnerable to deeper cuts.
• Healthcare costs offset pension savings: The €632 million saved in 2025 is dwarfed by the €10.9 billion rise in healthcare spending projected by 2035.
• Second-pillar pensions are a myth for most: Only a minority benefit significantly from employer-sponsored schemes.

What’s Next? The Reform’s Uncertain Future

The Belgian pension debate is far from over. Opposition parties are pushing for partial reversals of the reform, while unions demand restored indexation for low pensions. Meanwhile, the government faces pressure to address healthcare financing, which may require new taxes or benefit cuts.

One thing is clear: the reform’s savings come at a human cost. For civil servants, the message is clear—“your pension will be smaller.” For low-income retirees, the reality is harsher: “your pension will stagnate while others’ grow.” And for policymakers, the question remains: Is this the right trade-off for a sustainable future?

FAQ: Your Questions Answered

1. Will my pension be affected?

It depends on your sector and income. Civil servants and high earners will see the largest cuts (up to 15% reduction in replacement rate). Low earners and private-sector workers face smaller reductions (3–7%).

2. What about inflation? Will my pension keep up?

Only the portion of your pension up to €2,000/month will be fully indexed to inflation. Amounts above this threshold will be partially frozen.

3. Are second-pillar pensions still worth contributing to?

For most private-sector employees, the average supplement is just €28/month. Public-sector workers often benefit more from tax-free perks (e.g., company cars) than from formal pension top-ups.

4. Will this reform reduce inequality?

No—the opposite. The Bureau du Plan’s data shows the gap between the highest and lowest pensions will grow by 12% by 2035 due to frozen indexation and the end of targeted revaluations for poor retirees.

5. What’s happening with healthcare costs?

Healthcare spending is projected to rise by €10.9 billion by 2035 (2.6% annually), outpacing pension savings and increasing pressure on the social budget.
