The 4 pension pillars: why your statutory pension is never enough
Your statutory pension alone is not sufficient. Discover how the four pension pillars — statutory pension, IPT and VAPZ, private savings plans, and free investing — together form a strong pension plan.
By Jan Hermans, CEO & founder of Lyff.
Let’s make it clear once again: your statutory pension alone is not enough to live comfortably. This is not a doomsday scenario, but an arithmetic reality — and precisely why the Belgian pension system consists of four pillars, not one. Anyone who wants a strong pension plan needs to know these four pillars and understand how they complement each other.
Pillar 1: the statutory pension
The first pillar is the statutory pension that you build up through social security. For most self-employed individuals and company directors, this amount is well below the income they are accustomed to. The statutory pension forms the basis, but rarely more than that — and that is precisely why the next three pillars are so important.
Pillar 2: IPT and VAPZ
The second pillar revolves around supplementary pension accrual via your company or self-employment activity, with the most well-known forms being the IPT (Individuele Pensioentoezegging - Individual Pension Commitment) and the VAPZ (Vrij Aanvullend Pensioen voor Zelfstandigen - Free Supplementary Pension for the Self-Employed). Which of the two is most suitable depends on your specific situation.
A rule of thumb: if your salary is high enough, an IPT is often the better choice, because you can build up more capital with it. The VAPZ has a cap on the premiums you can contribute annually, while an IPT does not have that limit and therefore offers more room to accumulate capital.
Pillar 3: private savings plans
The third pillar is at the level of your private assets, separate from your company. Think of pension saving (pensioensparen) and long-term saving (langetermijnsparen). Both formulas yield a tax advantage of 30% on your contributions, which makes them an attractive addition to what you build up through the second pillar.
Pillar 4: free investing
The fourth pillar is everything that falls outside the first three: free capital that you build up yourself through ETFs, funds, or real estate. Here there is no fiscal framework as with pillars 2 and 3, but complete freedom to grow your capital in a way that suits you.
The best pension plan is not a single choice, but a combination
The best pension plan does not consist of just one pillar. It's not just an IPT, and it's not just an investment plan. A strong pension plan is how you optimally combine the four pillars, tailored to your income, your risk profile, and your long-term goals. Precisely there lies the added value of well-thought-out advice: not looking at each pillar separately, but making the whole work together.

Frequently asked questions
What are the 4 pension pillars in Belgium?
The four pension pillars are: (1) the statutory pension via social security, (2) supplementary pension accrual via IPT or VAPZ, (3) private savings plans such as pension saving (pensioensparen) and long-term saving (langetermijnsparen), and (4) free capital built up through ETFs, funds, or real estate.
Is an IPT better than a VAPZ?
That depends on your salary. With a sufficiently high salary, you can generally build up more capital with an IPT than with a VAPZ, because the VAPZ has a legal cap on the annual premium while the IPT does not have that limitation.
How much tax advantage does pension saving (pensioensparen) offer?
Both pension saving (pensioensparen) and long-term saving (langetermijnsparen) yield a tax advantage of 30% on the contributed amounts within legal limits.
Why is the statutory pension not enough?
The statutory pension is calculated based on your career within the social security system and is significantly lower for most self-employed individuals and company directors than their current income. Therefore, supplementary accrual via the second, third, and fourth pillars is necessary to maintain your standard of living.
What falls under the fourth pension pillar?
The fourth pillar includes all freely accumulated capital outside the other three pillars, such as investments in ETFs, funds, and real estate.
The engine of the second pillar: IPT and the 80% rule
For entrepreneurs with a management company, the Individual Pension Commitment (IPT) is often the most powerful lever in the financial control room. Unlike the VAPZ, where the premium is capped, the IPT allows you to set aside significant amounts tax-deductibly. The limit here is the 80% rule: your total pension (statutory plus supplementary) may not exceed 80% of your last normal gross annual salary.
This means your pension space is directly linked to your salary policy. Are you paying yourself too low a salary to save on taxes? Then you are unconsciously shrinking the basis for your IPT accrual. At Lyff. we often advise maintaining a balanced salary that protects both your current standard of living and your future pension space. A handy shortcut is the use of backservice, allowing you to fiscally favorably close gaps in your past pension accrual all at once.
Real estate as a leverage within your pension plan
One of the most underestimated strengths of the second pillar is its link to real estate. You don't have to wait until you're 67 to enjoy your IPT reserves. You can use the accumulated reserves as an advance for the purchase, construction, or renovation of real estate within the European Union. This allows you to finance private real estate with gross money from your company, without first having to pay a heavy private tax on a dividend distribution.
Imagine: you want to buy a second home on the coast. Instead of a classic mortgage that you pay off with net income, you can take out a bullet credit where the IPT reserve repays the capital in full at the end date. During the term, you only pay the interest privately. This is a fiscal shortcut that significantly increases your private liquidity. For more details on this strategy, you can refer to our expertise in real estate financing.
Frequently asked questions
Can I use my IPT capital for a renovation?
Yes, you can. You can take an advance on the reserves of your IPT or VAPZ for the acquisition, construction, improvement, or repair of real estate within the EEA. This is an excellent way to put funds from your company to good use for your private assets.
What happens to my pension accrual if I lower my salary?
If you lower your salary, your fiscal space within the 80% rule shrinks. This means you are allowed to contribute fewer premiums to your IPT. Therefore, it is crucial to have the impact on your pension planning calculated with every change in your salary optimization.
