Ask any self-employed person how much they pay in social contributions, and you’ll almost always get the same answer: “20.5% of my profit.” That’s the official rate, and it’s what you read everywhere.<\/strong><\/p>\n\n\n\n

But when we analysed our own anonymised data, 14,671 valid self-employed years from Belgian sole proprietorships, it turned out that for a large group this figure isn’t a realistic guideline: more than half of self-employed workers pay more than the official rate of 20.5%. And among those with an annual profit below \u20ac10,000, nearly one in three hands over more than half of that profit in social contributions<\/strong>. And that’s before personal income tax, VAT administration or accounting costs.<\/p>\n\n\n\n

In this article we summarise what we found, and what we believe needs to change.

Social contributions: the experiences of real self-employed workers<\/h2>\n\n\n\n

Every week we hear the same story from different self-employed people: contributions that have nothing to do with what they earned.<\/p>\n\n\n\n

Ante Vriens, beauty specialist and owner of Skin-First<\/strong>: “After my baby was born I wasn’t working, but the social contributions kept running: \u20ac1,980. Money that had to come out of my savings account.”<\/p>\n\n\n\n

Sofie Dejonghe, freelance social media expert<\/strong>: “From the very start I simply assumed I’d only keep 50% of my income. I didn’t go into it naively.”<\/p>\n\n\n\n

And Thomas Bertrem, physiotherapist<\/strong>: “The stress around social contributions is the same as the stress around income tax. There’s so much uncertainty. You can estimate your monthly income, but in the end it always swings by a few thousand. You have to be lucky enough to know it, or have someone tell you, and either way build up a reserve.”<\/p>\n\n\n\n

Three different professions, one shared feeling: the system isn’t quite right<\/strong>. And we wanted to know whether the data confirms that feeling.<\/p>\n\n\n\n

How much do you have to pay in social contributions as a self-employed person?<\/h2>\n\n\n\n

On paper, a self-employed person working full-time pays 20.5% of their net taxable professional income (profit before tax)<\/strong>. But there’s a legal minimum contribution of \u20ac890.42 per quarter in 2026<\/strong>, regardless of what you earn, including when you’re running at a loss, plus a ceiling of around \u20ac5,100 per quarter.<\/p>\n\n\n\n

That fixed floor creates a tipping point: it’s only from \u20ac17,374 in annual profit that 20.5% of profit roughly matches the minimum contribution.<\/strong> Below that amount, you pay proportionally more than 20.5%. And the lower the profit, the higher that percentage. This is what makes the system regressive: those who earn the least pay proportionally the most.<\/strong><\/p>\n\n\n\n

The data shows that 58% contribute too much<\/h2>\n\n\n\n

Of all the self-employed workers in our sample, only 42% pay the expected rate of 20.5% or less, as the system intends. The rest:<\/p>\n\n\n\n
