Buying into your pension fund: what is it for?

Pension fund buy‑ins: what does it mean?

A pension fund buy‑in consists of making voluntary contributions to your occupational pension scheme (2^nd pillar), in addition to the mandatory contributions paid by you and your employer.

This mechanism allows you to fill pension gaps and increase future benefits, both at retirement and in the event of disability or death.

Why consider a buy‑in to the second pillar?

When integrated into a broader wealth‑planning approach, pension fund buy‑ins can offer several advantages. 

Filling pension gaps 

Pension gaps may arise during the course of a career, for example in the event of:

• career interruptions or reduced workloads,

• part‑time employment,

• salary increases,

• a change of employer,

• divorce, following the division of second‑pillar assets.

Buy‑ins make it possible to rebuild your pension capital and improve the benefits you will receive at retirement.

Using pension buy‑ins as a tax‑planning lever 

Amounts paid into the pension fund as part of a buy‑in are generally fully deductible from taxable income. They also make it possible to transfer assets subject to wealth tax into a tax‑advantaged pension framework.

When properly planned and compliant with the applicable rules, buy‑ins can form part of an effective tax‑optimisation strategy.

Strengthening protection against unforeseen events 

Beyond retirement benefits, pension fund buy‑ins may also enhance:

• benefits in the event of disability or illness,

• financial protection for your dependants in case of death.

They therefore contribute to securing your overall financial situation, not only your future retirement income.

In which situations are buy‑ins possible? 

The possibility of making buy‑ins depends on the rules of your pension fund’s regulations. Opportunities for buy‑ins may arise in particular when:

• your insured salary increases,

• your pension plan is improved,

• you return to work after a career break,

• pension assets have been transferred following a divorce.

Caps and conditions apply to avoid over‑insurance, making a personalised analysis essential.

Spreading buy‑ins over time

Making buy‑ins over several years may offer an additional tax advantage, by smoothing income‑tax progression over time.

However, care should be taken not to reduce taxable income to zero, as some of the tax benefit may then be offset when pension capital is later taxed upon withdrawal.

The importance of personalised advice

A pension fund buy‑in is a structuring wealth‑planning decision. Its relevance depends on many factors, such as:

• your age,

• your retirement horizon,

• your family situation,

• the quality and structure of your pension fund,

• your future plans (early retirement, property purchase, expatriation).

Professional advice helps integrate pension buy‑ins into a coherent overall strategy, while avoiding pitfalls and maximising their benefits.
