Supply income as a pensioner or employee
Looking for a flexijob?
Would you like to earn some extra on the side in a tax-efficient way? Then a flexijob is the ideal solution for you! The unique flexijob system in Belgium offers you the chance to earn additional income without paying high taxes or social security contributions. At TRIXXO Jobs, we are happy to help you find the perfect flexi-job vacancy that matches your availability and wishes. Read on and find out all about flexi-job conditions and which sectors you can get started in.
Why is a flexijob so interesting?
A flexi-job is a special status in Belgium that lets you earn extra income in a tax-friendly way, on top of your main income or your pension. You pay no taxes and no social security contributions on your flexi-wage: what you earn gross, you keep net. And you continue to build up social rights.
What are the conditions of a flexi job?
Not everyone is eligible for a flexijob. Belgian legislation has drawn up specific conditions to regulate the system of flexi jobs. Here are the main conditions:
For employees
To qualify for a flexi-job, you must have worked at least 4/5 (80%) for one or more other employers during reference quarter T-3. That's the third quarter before your flexi-job. Planning to start in Q3 (July–September)? The NSSO will then check your employment in Q4 of the previous year (October–December). This is verified automatically through your social security records.
For pensioners
Are you retired? Then you can earn an unlimited, tax-free additional income through a flexi-job. There's no ceiling and no 80% requirement. Since 1 July 2026 you can also start straight away: as soon as you're registered in the pension register during the quarter of your flexi-job, you're good to go. With your previous employer you do have to wait one quarter. With any other employer you can start immediately.
Are you on early retirement? Then income rules do apply. Our consultants are happy to go through it with you.
In what sectors can you earn extra money through a flexijob?
From now on, you get to choose where you want to earn extra income. For years, flexi-jobs were limited to a handful of sectors and were particularly popular in the hospitality industry. Now, nearly the entire job market is open—both private and public: retail, warehousing, healthcare, construction, office work… A complete overview here.
