Flexi-job calculator 2026: flexi wage, net and ceiling
With a flexi-job you earn extra next to a main job or your pension, without social security contributions and usually without tax. Enter your hourly wage and hours and see what you keep, whether you stay under the tax ceiling and whether your hourly wage is within the hospitality limits.
Calculate what your flexi-job pays
You can still earn €17,837.05 tax-free from flexi-jobs this year.
Your employer pays a special contribution of €168.83 on top (28%).
How we calculate
- Your flexi wage comes with 7.67% flexi holiday pay, paid together with your wage. No employee social security contributions are deducted, so gross is net.
- If you are not legally retired, your flexi income stays tax-free up to 18,440 euros in 2026. Anything you earn above it is taxable; the tool shows how much, but does not calculate the tax itself because it depends on your full return. There is no ceiling for pensioners.
- In hospitality your flexi wage may not be lower than 12.11 euros an hour since 1 September 2026 (13.04 with flexi holiday pay) and, according to the NSSO, not higher than 21.00 euros (22.61 with flexi holiday pay). That maximum is indexed from the first index threshold crossing after 1 July 2026.
- In other sectors your base hourly wage must at least reach the pay scale of your job, or the average minimum monthly income if there is no scale, converted to an hourly wage. The base wage may be at most 150% of that minimum; bonuses and supplements from the law or a collective agreement no longer count towards that since 1 July 2026. Because the scale differs per job, the tool does not check that minimum.
Who may do a flexi-job
Three quarters earlier (quarter T-3) you must have worked at least 80% of a full-time job for one or more other employers, or be legally retired. You may not do a flexi-job with the employer you already work for in the same quarter, nor during a period covered by a severance payment from that employer.
If you went from full-time in T-4 to 80% in T-3, you may not do a flexi-job for two quarters. Work as a student at the solidarity contribution, as a young person until the year you turn 18 or as a flexi-jobber itself does not count towards that 80%. Artistic functions, functions in the healthcare professions and sex work are excluded.
In which sectors
Since 1 July 2026, flexi-jobs are in principle possible across the private and public sectors. Not allowed are domestic staff (PC 323), funeral directors (PC 320, except workers employed like occasional workers), agriculture (PC 144), horticulture (PC 145, except laying out and maintaining parks and gardens) and sea fishing (PC 143, except shore staff and warehouses), with a ban at fish auctions too. In the service voucher sector a flexi-job is only possible during the first three months. Sectors can still ask to opt out, so the list may change.
Frequently asked questions
How much do I keep net from a flexi-job?
All of it: your flexi wage plus 7.67% flexi holiday pay, without social security and without payroll tax, as long as you stay under the annual tax ceiling. At the hospitality minimum of 12.11 euros an hour, that is 13.04 euros an hour.
How much may I earn with a flexi-job?
There is no limit on what you earn, but there is one on what is tax-free: 18,440 euros in 2026 if you are not retired. Above it, the excess is taxed. For social security you remain a flexi-jobber above the ceiling too. You follow your counter on mycareer.be.
Do I build up social rights with a flexi-job?
Yes, your work in principle counts like that of an ordinary employee, including for holiday days. Because you already get your flexi holiday pay with your wage, nobody pays you wages or double holiday pay when you take those holiday days.
What does the employer pay for a flexi-job?
A special employer contribution of 28% on the full flexi wage, flexi holiday pay included, and no ordinary social contributions. They sign a written framework agreement with you and a flexi employment contract per assignment, and file a Dimona FLX.
