Questions about a vacancy?
Contact your job adviser at Experza with your questions about a vacancy.
Do you like working with your hands? Find out whether and how you can work as a flexi in the construction sector. On your flexi-wage you pay no employee contributions, and no tax up to 18,440 euros (income year 2026); anything above that is taxed.
With a flexi-job you earn extra alongside another job or your pension. You cannot combine a regular job and a flexi-job with the same employer. Below you can read who can do a flexi-job and what is possible in construction.
Since 1 July 2026, a flexi-job is possible in almost all sectors; whether it is possible for a given job depends on the rules of the sector. Construction is not on the list of excluded sectors. However, the construction sector (PC 124) has already announced specific restrictions: flexi-jobbers who are not retired can be limited to jobs that do not require basic safety training, such as administration, workshops, warehouses or logistics. Retirees are subject to their own rules in construction.
For a flexi-job, you must in principle have worked at least 4/5 for one or more other employers in the third quarter before the flexi-job, or be retired. Retirees can in principle also do a flexi-job; contact the Federal Pensions Service in advance, so you are sure that your flexi-job has no effect on the amount of your pension. If you are a student and did not work at least 4/5 in the third quarter before the flexi-job, you do not meet the condition.
That depends on the job. Jobs that require basic safety training may fall outside the flexi-job for people who are not retired. As a flexi-jobber you must also have the required diplomas and qualifications: the rules on protected professions still apply. You can see which jobs are available now among the vacancies on this site.
Your flexi-wage must be at least the minimum wage that applies to that job. On your flexi-wage you pay no employee contributions, and no tax up to 18,440 euros (income year 2026); anything above that is taxed. That ceiling does not apply to retirees. If you are retired and have reached neither the legal retirement age nor 45 years of career, from 2026 you can earn at most 8,121 euros a year with a flexi-job.
Since 1 July 2026, a flexi-job is possible in almost all sectors; whether it is possible for a given job depends on the rules of the sector. In 2026, sectors can apply for an opt-out every quarter, and from 2027 every year, so the rules may still change. For income year 2026, the tax ceiling is 18,440 euros.
