Frequently asked questions
Do you build up social security rights with a flexi-job?
Yes. Even though you don’t pay taxes or social security contributions on your wages, you still build up social security rights. This means the hours you work count towards your pension, your holiday pay and any unemployment benefits in the future.
Do you pay taxes on a flexi-job?
That depends on whether you’re working or retired.
- Employee (at least 4/5): up to €18,440 per year (2026). This amount goes up every year with indexation. Anything you earn above that is taxed as normal.
- Retired: no limit.
Have you taken early retirement, so you’re under 66 and don’t have a 45-year career? Then your pension goes down if you earn more than €8,121 extra in 2026.
In which sectors can you do a flexi-job?
Since 1 July 2026, it’s possible in almost all sectors, private and public. Think of shops, warehouses, production, offices, education, healthcare and hospitality. Before, it was only possible in a limited number of sectors.
In healthcare, you can only do a flexi-job if you have the legally required diploma. Sectors can also still opt out later. Your consultant knows which jobs are eligible.
Who can do a flexi-job?
Two groups can do a flexi-job: employees who work at least 4/5 and retired people.
- You work at least 4/5: three quarters before your flexi-job, you must have worked at least 4/5 of a full-time job, with a different employer. This condition is checked again every quarter.
- You’re retired: you can start right away, from the quarter in which you retire. The 4/5 rule doesn’t apply to you. Want to do a flexi-job with your last employer? Then wait until the quarter after you retire.
What is a flexi-job?
A flexi-job is a side job with its own favourable status. You don’t pay social security contributions, and up to a fixed amount per year, you don’t pay taxes either. So what you earn gross, you get net. Your employer does pay a special contribution of 28% on top of your wages.
You work with short contracts, each time for a fixed period.
