Group insurance payout in Belgium: how much tax do you pay?

The short answer: your group insurance is taxed when it pays out, but far more lightly than salary. From the gross capital, a 3.55 percent RIZIV contribution (health insurance) is deducted first and, since 1 January 2026, a flat solidarity contribution of 2 percent. On what remains you pay 10 percent tax if you work until the statutory retirement age or have a full career of 45 years, and 16.5 percent if you stop earlier. Municipal tax comes on top. From a capital of 100,000 euros you keep roughly 84,000 euros in the best case. Below you can read exactly how that calculation works, when you fall into the higher rate and where you can see how much has already been set aside for you.

What group insurance actually is

A group insurance is the supplementary pension your employer builds up for you: every month a percentage of your gross salary goes to an insurer or pension fund, sometimes with a contribution of your own on top. In industry it is almost standard in the package, alongside the shift premium and meal vouchers, and in sectors such as metalworking, construction, food and chemicals it often runs through a sector pension plan that every employer takes part in. The law guarantees a minimum return on contributions: since 1 January 2025 that is 2.50 percent a year, after 1.75 percent in the years 2016 to 2024. In principle you only receive the capital when you take your statutory pension, and that is exactly when you want to know what the tax authorities will take from it.

What comes off your capital

The deductions happen in a fixed order. First the insurer withholds the 3.55 percent RIZIV contribution on the full gross amount, profit sharing included. Then comes the solidarity contribution: until the end of 2025 it was 0 to 2 percent depending on the amount, since 1 January 2026 it is 2 percent for everyone. Only then is tax calculated on the balance, and that depends on your age and your career at the time of payout. Profit sharing, the extra return the insurer grants on top of the guarantee, is exempt from tax, but does pay the RIZIV and solidarity contributions. Finally, the municipal tax of your place of residence is added to the tax itself, usually 6 to 9 percent of the tax amount. That is why in practice the insurer withholds 10.09 or 16.66 percent instead of 10 or 16.5 percent.

10 or 16.5 percent: what determines the rate

For the part your employer paid, the lowest rate of 10 percent applies in two cases: you have the capital paid out at the statutory retirement age, 66 since 2025, and you stayed in active work for the last three years; or you have a full career of 45 years behind you, even if you are not yet 66. In all other cases from age 62 you pay 16.5 percent. At 60 or 61 it is 16.5 percent if you retire, and 20 and 18 percent respectively if you claim the capital without stopping work. For the part you contributed yourself, it is simpler: 10 percent on contributions since 1993 and 16.5 percent on older contributions. So if you started working in the nineties or later, you are almost always at 10 percent on your own part. The lesson for a technician planning the end of their career: working your final years right up to your retirement date saves 6.5 percentage points on the largest part of your capital.

A worked example with 100,000 euros

Suppose your employer built up 100,000 euros of capital for you over your career and you have it paid out at 66, having simply worked your last few years. First 3,550 euros of RIZIV contribution and 2,000 euros of solidarity contribution are deducted, leaving 94,450 euros. On that you pay 10 percent tax, 9,445 euros, and with a municipal tax of 7 percent another 661 euros. Net, you receive roughly 84,344 euros. If you stop at 63 without a full career, the tax becomes 16.5 percent or 15,584 euros, plus 1,091 euros of municipal tax: roughly 77,775 euros net. The same capital, a difference of more than 6,500 euros. Compare that with salary: from a 100 euro gross raise, a technical profile often keeps only 40 to 50 euros, as we calculate in what does an automation engineer earn. That is why a good group insurance carries more weight than it seems to in the job advert.

Where to check how much has been set aside for you

You do not need to keep your old payslips. On mypension.be, under My supplementary pension, you can see per pension plan the reserves built up for you on 1 January, an estimate of the capital if you stay with your employer until retirement, and what your survivors receive if you die. Plans from previous employers are included too, because every insurer and pension fund reports the balance annually to the DB2P database of Sigedis; the figures are refreshed every year towards the end of August. If you change jobs, your reserves stay yours: they remain with the old insurer or move with you to the new plan. If you pay an employee contribution yourself, you also get a 30 percent tax reduction on it, offset straight away in your withholding tax. So in a salary negotiation, do not just ask about gross pay, but also about the contribution percentage of the group insurance and who pays it; your pay package explained shows how to weigh that up properly.
