So, you’ve got your Professional Card, and you’re freelancing in Belgium. That’s great!
Next, it's time to tackle the essentials - understanding how taxes, social security, and VAT work. While it's not the most thrilling part of freelancing, getting it right is mandatory and saves you money in the long run.
Freelancers are taxed under the personal income tax system, which is progressive. The more net income you earn, the higher your rate. You get to deduct business expenses and social security contributions.
The 2024 income tax brackets (for income earned in 2024, assessed in 2025)8 are:
| Bracket | Rate |
|---|---|
| €0 to €15,820 | 25% |
| €15,820 to €27,920 | 40% |
| €27,920 to €48,320 | 45% |
| Above €48,320 | 50% |
There is a tax-free allowance (a base amount you don’t pay tax on). For 2024, that’s around €10,570.
Freelancers in Belgium must pay social security contributions to a social insurance fund every quarter.
These payments cover essential benefits such as pensions and healthcare.
For new freelancers, the contributions usually start at a provisional minimum rate until their exact net income is determined.
After around three years, the fund recalculates the amount based on actual income.
For new freelancers, the rate is 20.5% for the first year. After that, the standard rate is 21.5% on income up to a certain threshold (at which point the rate decreases). Meanwhile, contributions may plateau or slightly decrease once income exceeds certain thresholds7.
Being proactive with the payments and understanding how your rates adjust over time can help you manage your finances more confidently as your freelance income grows.
Freelancing in Belgium can be an exciting adventure. You get to work on your own terms while enjoying everything this vibrant country has to offer.
Sure, there’s some paperwork at the start, getting your visa, registering your business, and setting up taxes and social security, but once that’s done, you’re all set for smooth sailing.
Therefore, if you’re looking for a place that truly values freelancers, Belgium checks all the boxes. A steady economy, supportive community, and plenty of room to grow your business are perks you won’t find everywhere!
