One of the biggest advantages of a flexi-job is that your net income is often almost equal to your gross income. However, it’s important to know when you do pay taxes on your flexi income. This mainly depends on your status: are you not retired, early retired, or legally retired?
Below we explain everything clearly.
Do you combine your regular job with a flexi-job? Then there is an income threshold of €18,000 net per year, which is indexed annually.
If you stay below this amount, you do not pay taxes on your flexi income.
If you earn more than €18,000, withholding tax is applied on the amount above the threshold.
Good news: you don’t have to track everything yourself. Through the flexi counter on www.mycareer.be you can easily see how much you have earned so far.
For early retirees, a lower income threshold applies so that your pension is not affected. In 2026, this limit is €8,121 net per year.
If you stay under this amount, your flexi income does not affect your pension.
If you exceed it, it may have consequences.
Because this threshold can vary depending on your personal situation, we recommend contacting your pension service to know your exact limit.
If you are legally retired, you can earn unlimited extra income through a flexi-job. There is no income ceiling.
However, it is still wise to check with your pension service if there are any specific considerations for your situation.
Now that you have clarity about taxes on your flexi income, you can look for a job that suits you. Check out our current flexi vacancies.
