How much do the self-employed in Belgium really earn? Which professions generate the highest turnover, and where in the country can a starter reach €100,000 the fastest?

With the Accountable Index, based on anonymised data from 11,803 self-employed professionals, we provide a unique view of income patterns, regional differences, and surprising trends in Belgian entrepreneurship.

Income by profession: who earns the most?

Not every profession is equally lucrative. Here are the median annual turnovers for full-time self-employed professionals, according to the Accountable Index:

  1. Doctors – Physicians take the undisputed top spot, with a median turnover of €200,000. Their expertise and high level of responsibility are clearly reflected in their income.
  2. Car dealers – In second place are car dealers, generating a solid median turnover of €160,000. The combination of demand for mobility and commercial margins makes this a particularly lucrative profession.
  3. Financial advisors & brokers – With a median turnover of €135,000, financial advisors and brokers show that high-quality service and trust pay off.
  4. Consultants & IT professionals – Consultants and IT specialists earn an average of €100,000. Their income grows rapidly thanks to the scalability of digital solutions and the ongoing demand for technical expertise.
  5. Engineers & technical consultants – These professions also score high, with a median turnover of €100,000. Their earnings reflect the strong demand for technical knowledge and problem-solving skills.
  6. Sales representatives – With a stable €90,000 turnover, sales representatives demonstrate that commercial acumen and strong client relationships are consistently rewarded.
  7. Construction professionals – The construction sector firmly ranks in the top ten, with a median turnover of nearly €85,000. Interestingly, construction professionals outperform many traditional white-collar roles.
  8. HoReCa entrepreneurs – Despite often high workloads, hospitality operators have a median turnover of €65,000. A clear example of a sector where passion often takes priority over profit.
  9. Designers and photographers – Creative professions such as designers, photographers, and coaches earn between €45,000 and €55,000. Many professionals in these fields work part-time or combine multiple activities.
  10. Small retailers – Small shop owners achieve a median annual turnover of €48,000. Local traders often face high fixed costs, rising e-commerce competition, and thin margins, yet they remain vital for the vibrancy of cities and towns.
  11. Architects – Surprisingly, architects close the list with a median turnover of only €45,000, despite their extensive education and significant responsibility.

How quickly do self-employed professionals reach €100,000 turnover?

The speed at which self-employed professionals reach €100,000 in turnover varies significantly by profession:

  • Consultants & IT professionals: on average 1.5 years.
  • Paramedical professionals, construction professionals, sales representatives & HoReCa operators: less than 2 years.
  • Architects, urban planners & real estate agents: 3 years on average.
  • Most other professions take more than 3 years to reach a €100,000 annual turnover.

Regional differences: Flanders, Wallonia & Brussels

The Accountable Index reveals some striking contrasts between the regions:

  • Car dealers in Flanders earn the most in Belgium, with a median turnover of €138,971.
  • Construction professionals perform well everywhere, but do even better as a secondary occupation in Wallonia.
  • Lawyers in secondary occupation rank highest in Brussels (€79,915) and Flanders (€61,015).
  • Artists are among the lowest-earning groups across all regions.
  • Marketing professionals earn much more in Brussels (€89,523) than in Flanders or Wallonia (~€50,000).
  • Paramedical professionals achieve the best results in Brussels (€82,760).
  • Photographers show significant regional inequality, ranging from €54,134 (Wallonia) to €61,630 (Brussels).

Flanders

Zooming in on Flanders, it’s clear that in Antwerp the entrepreneurial spirit is stronger than ever.

According to the Accountable Index, the average annual income of a full-time self-employed professional in Antwerp is €60,659, while part-timers (secondary occupation) average €14,290.

Top earners in Antwerp:

  • IT Professionals: €119,384 median annual turnover
  • Consultants: €111,593
  • Construction professionals: €100,074
  • Drivers & couriers: €94,097
  • Teachers: €88,883

What stands out is that consultants and IT professionals in Antwerp reach their first €100,000 turnover about 25% faster than in Brussels, and even 60% faster than in West Flanders.

Yet, in terms of overall turnover, Antwerp ranks only third, after Walloon Brabant and Limburg. A possible explanation? Intense competition in a densely populated, entrepreneurial city.

Wallonia

Heading south, we find that Walloon Brabant is the hotspot for freelancers.

The average annual income there amounts to €59,725 for full-time self-employed professionals and €18,295 for those in secondary occupation.

Top earners in Walloon Brabant:

  • Consultants & IT professionals: €136,132 median annual turnover — the highest figure in all of Belgium (national average: €101,347)
  • IT specialists (alone): €135,451 median turnover, also the absolute top nationwide
  • Engineers: rank among the best-earning groups in the province

  • Best-performing region: Wallonia (€109,350)
  • Top province: Walloon Brabant (€135,451)

The availability of your team to help and guide people to understand their finances better is what really makes Accountable valuable. While the AI is able to give answers to most basic questions, specific scenarios need counsel from a human which your team performs beautifully.

They always answer for questions wherever is via direct e-mail or through app. If they can’t answer fully they will forward you to the right place. Documents were always prepared well and ready to send further to government. Everything is intuitive in the app and easy to sort out even for someone completely green in this field.
