What tax costs a one-person company in Belgium, 2026
Six turnover bands, the 2026 rule set, and the same engine behind every calculator here. Quote any row — the basis is printed below it so anyone can reproduce the number or argue with it.
These figures are what tax and social contributions take BEFORE any profit is distributed to the owner. Taking money out — as a dividend, or by winding the company down — costs more on top, and that is a separate decision.
| Turnover | About | Tax + contributions | Share of turnover | Left over |
|---|---|---|---|---|
| €60,000 | €286/day | €13,019 | 21,7% | €34,981 |
| €80,000 | €381/day | €18,726 | 23,4% | €49,274 |
| €100,000 | €476/day | €23,726 | 23,7% | €64,274 |
| €120,000 | €571/day | €28,726 | 23,9% | €79,274 |
| €150,000 | €714/day | €36,226 | 24,2% | €101,774 |
| €200,000 | €952/day | €48,726 | 24,4% | €139,274 |
Day rates are the turnover divided by 210 billable days — a rough way to find your own row, not an assumption in the figures. “Left over” is turnover minus business expenses minus the column before it, and it sits partly in the company and partly with you.
How these were computed
Turnover is the only thing that changes between rows. Everything else is held at the values below and disclosed, because a figure without a basis is a claim rather than a reference.
- Legal structure
- One-person BV / SRL
- Business expenses
- €12,000
- Director salary
- €30,000
- Dependent children
- 1
- Existing pension contribution
- €1,800
- Billable days
- 210
What this table does not answer
How much of what is left ends up in your own account. That depends on the salary and dividend decision, which is the one worth actually optimising — a fixed assumption per row would be a guess dressed up as a reference figure.
Citing these figures
