When you take out pension saving.

Main differences

Note on premium tax: the 2% insurance premium tax applies to regular (non-pension) life insurance and to long-term savings (langetermijnsparen) — pension savings products (fund and insurance) are exempt in all three forms (source: Wikifin).

When is a pension savings fund usually more advantageous?

• Long horizon (15+ years until retirement): historically higher return amply compensates for the fluctuations.
• Low costs: make a comparison — some funds charge 0.5-1% TER, others 1.5-2%. Ask for the all-in costs on your proposal.
• Those who can tolerate fluctuations: anyone who would panic-sell during a crash is better off choosing the guaranteed branch 21.

Popular pension savings funds in Belgium (illustrative, not as a recommendation):

• BNP Paribas Fortis — Pension Fund High Equity / Low Equity
• KBC — Pricos Defensive / Balanced
• Belfius — Pension Fund (High Equities / Balanced Plus)
• Argenta — Argenta Pension Fund

Note: AXA’s pension savings product (“Pension Plan Fisc”) is an insurance contract (branch 21 / branch 23), not a mutual fund, and therefore does not belong in this list of pension savings funds.

Differences between them lie mainly in the equity-to-bond ratio, costs, and historical returns.

When is a branch 21 pension savings insurance more advantageous?

• Short horizon (5-10 years until retirement): no time to sit out fluctuations.
• Those who absolutely do not want volatility: a guaranteed minimum is psychologically important.
• Estate planning: the insurance structure can designate beneficiaries outside the estate.

And branch 23?

Branch 23 is an insurance wrapper around an investment fund. It often gets the worst of both worlds: fluctuations + higher costs than a direct fund.

When it does make sense:
– For those who want to combine insurance-specific features (designated beneficiary on death, estate planning) with market-linked returns.

Note: within the pension savings regime, all three forms (fund, branch 21, branch 23) are taxed via the 8% anticipative tax at age 60. The so-called “8-year rule” — exemption from withholding tax (roerende voorheffing) after 8 years — applies only to non-pension individual branch 21 life insurance, not within pension savings. Branch 23 has no withholding tax to exempt in the first place.

When it makes less sense:
– With high entry and management costs — always calculate all-in.
– For pure investment purposes with a long horizon: a fund (ETF or classic pension savings fund) is usually cheaper.

Practical decision

Decision tree:

1. How many years until retirement? <10 years → branch 21. >15 years → fund or branch 23.
2. Fluctuations acceptable? No → branch 21. Yes → fund.
3. Estate consideration? Yes → insurance (branch 21/23). No → fund.
4. Compare costs. Fund TER + 1% management = effective cost. Under 1% all-in is excellent; above 2% is questionable.

The real impact

Over a long horizon, the difference can grow enormously. A quick calculation example:

• Person A — pension saving €1,350/year in a branch 21 with 2.5% net return.
• Person B — pension saving €1,350/year in a fund with 6% net return.

After 30 years:
– Person A: ~€60,000.
– Person B: ~€110,000.

The €50,000 difference comes solely from the return gap — not from contributions. Not nothing.

💡 The choice remains personal and depends on risk appetite and horizon. But put the numbers side by side before you choose.
