Pension savings 2026: the third pillar for the self-employed in Belgium

Any Belgian tax resident aged 18 to 64 (inclusive) with taxable professional income can open a pension savings plan. This includes:

• the self-employed, whether as a sole proprietor or through a company (payments are personal, with no impact on the company);
• company directors (manager of an SRL/BV, director of an SA/NV), in a personal capacity;
• employees, civil servants, liberal professions and anyone with professional income subject to personal income tax (IPP/PB);
• working pensioners who continue an activity generating taxable professional income.

Excluded are people with no taxable professional income (the tax reduction then has no effect), and payments made after the 64th year (the scheme closes at 65).

The tax mechanism mirrors that of the PLCI, only simpler: a federal tax reduction on the way in, 8% early taxation at 60, then the capital is free of tax.

For a payment of €1,050 (30% regime):

• Federal income tax reduction: 1,050 × 30% = €315.
• Actual net cost: 1,050 − 315 = €735.
• Leverage effect: ~1.43×; for every €1 you actually pay out, you build up ~€1.43 in your pension pot.

The leverage effect is much more modest than with the PLCI (~3.4× for €50,000 of income), which is to be expected: pension savings are a top-up, not the main pillar. Their purpose is to add an extra tax building block at almost no opportunity cost once set up (automatic standing order).

No effect on social security contributions: unlike the PLCI, which also reduces the NISSE contribution base, pension savings only affect personal income tax. This is one of the features that distinguishes the second and third pillars.

A special feature of the third pillar: early taxation at age 60 applies automatically, whether or not you withdraw your capital. On the capital built up by your 60th birthday, the State takes 8% once and for all, and everything that accumulates after that is tax-free.

How it works:

• At 60, your provider calculates the taxable capital (total payments + interest + capital gains up to that date).
• The 8% early tax is levied on this taxable capital (not on later payments).
• You can keep paying in until 64 (with a tax reduction), and growth after 60 is no longer taxed on payout.

1. Opening pension savings before the PLCI. PLCI leverage ~3.4× vs ~1.4× for pension savings. Always max out the PLCI first.
2. Choosing Branch 21 by default without comparing. Over 25+ years, the difference in return between a fund and Branch 21 typically adds up to 50-100% more final capital. Assess your risk profile honestly.
3. Only paying in December. You lose 9 months of growth every year. Set up a standing order in January.
4. Withdrawing before 60. 33% tax + loss of the accumulated reductions = value destroyed. In an emergency, use ordinary savings, never the third pillar.
