Belgium is famous for waffles, chocolate, and historic cities—but if you're living or working there, you're likely just as interested in one more thing: taxes. Known for its high tax structure, Belgium consistently ranks among the countries with the highest income tax rates in Europe.
If you're wondering about the Belgium tax rate for foreigners or why Belgium tax rates are so high, this guide breaks it down clearly and simply.
Belgium Tax Rate Overview
Let’s start with the basics. Belgium follows a progressive tax rate system, meaning the more you earn, the more you pay in taxes.
Here are the current income tax brackets for residents (2025):
- 25% for income up to €15,200
- 40% for income between €15,201 and €26,830
- 45% for income between €26,831 and €46,440
- 50% for income above €46,441
Yes, you read that right. The top rate is 50%, and it kicks in at fairly moderate income levels compared to countries like the US or the UK. That’s a major reason why people often ask: “Why is Belgium tax so high?”
Standard Rate: 25% and More
While 25% is the standard rate for the first tax slab, it's important to remember that higher earners quickly fall into the 40–50% range. This tax rate doesn’t include additional surcharges, like municipal or communal taxes.
Communal Taxes: Hidden in Plain Sight
Apart from federal income tax, Belgium imposes communal taxes. These are levied by local municipalities and vary between 0% and 9% of the income tax due, depending on where you live.
Most major cities like Brussels and Antwerp levy communal tax rates ranging from 2.5% to 9.5%, which are calculated on top of your income tax. That means your total effective tax rate could be even higher than 50%!
So, if you're moving to Belgium or planning to work remotely from there, check your local communal rate—it makes a big difference.
Belgium Tax Rate for Foreigners
Wondering how taxation works if you're not a Belgian citizen?
Belgium tax rate for foreigners can be just as high as for residents, depending on your income and duration of stay. However, Belgium does offer:
- Expat tax regimes (for certain inbound professionals)
- Tax treaties to avoid double taxation
- Non-resident status (only taxed on Belgian-sourced income)
If you're on a short-term assignment or work remotely for a non-Belgian company, you may still be liable under Belgium’s income tax laws if you stay longer than 183 days.
Always use a reliable Belgium tax calculator for foreigners to estimate your tax liability before committing.
Corporate and Withholding Tax Rates
Apart from personal income, Belgium also imposes corporate taxes. The standard corporate tax rate in Belgium is 25% as of 2025.
And for passive income like dividends or royalties?
- 30 per cent on dividends, royalties, and interest payments
These are flat withholding taxes, usually deducted before the payment is made to you.
However, tax treaties and EU rules may reduce these rates for certain international residents or companies.
How to Pay Taxes in Belgium
Taxes in Belgium are collected by the Federal Public Service Finance (FPS Finance). Here’s how the system works:
- Employers deduct tax at source (Pay-As-You-Earn or PAYE system)
- Freelancers or self-employed individuals make quarterly advance payments
- All taxpayers must file an annual tax return (usually in June)
Filing can be done online through Tax-on-web, the government’s digital tax platform. Most employees will get a pre-filled return, but you should always verify it carefully.

- Gross vs net income

- Applicable communal taxes
- Potential deductions and credits

Why Is Belgium Tax So High?
You’re not alone if you’re asking this question.
Belgium has a highly developed social welfare system that provides:
- Universal healthcare
- Generous unemployment benefits
- State-funded education
- Infrastructure and social security
To fund all this, the country relies heavily on direct taxation, especially on personal income. While this may seem like a burden, it also translates into a high standard of living and public services.
Still, reforms are on the table. The Belgium tax rates 2025 discussion includes proposals to lower income tax slabs and shift the burden toward consumption taxes like VAT.
