Belgium has some of the highest taxes on salaries in the world. Federal rates reach 50%, local surcharges add more, and employee social security takes 13.07%. For skilled people moving in, though, the inbound regime now gives 35% of pay tax-free with no upper cap. And from 2026, Belgium has its first general capital gains tax, at 10%.
This guide covers Belgian personal tax for people moving to or living in Belgium in 2026.
The key question is simple. Do you qualify for the inbound regime, and how will the new capital gains tax affect your investments?
What's changed: the Law of 18 December 2025 raised the inbound allowance from 30% to 35%, removed the €90,000 cap and cut the salary threshold to €70,000, retroactive to 2025. A new 10% capital gains tax on financial assets, including crypto, became law on 6 April 2026 and applies from 1 January 2026.

When you become tax resident in Belgium
You're a Belgian tax resident if your home (domicile) or the seat of your wealth is in Belgium. Registering in the population register creates a legal presumption that you're resident. Residents are taxed on worldwide income.

Income tax and social security
Belgium taxes earned income at progressive federal rates of 25%, 40%, 45% and 50%. The 50% band starts at around €50,000 of taxable income, and bands are indexed each year. Your commune then adds a surcharge of 0% to 9% of the tax due. Employees also pay 13.07% social security with no ceiling, and employers pay around 25% to 27% on top.
Worked example
You're employed in Brussels, earning about €87,000 (roughly US$100k).
Social security at 13.07% costs about €11,370, and the standard allowance for professional expenses comes off.
Most of your remaining income falls in the 45% and 50% bands, and the communal surcharge adds about 7% to the tax.
Your all-in bill is about 45% of your salary. Under the inbound regime, about 27%.
The inbound regime
Why does this regime matter so much? Because 35% of a qualifying employee's pay becomes tax-free, which can cut the all-in rate by almost half.

There are two routes:
Inbound taxpayer: employees and company directors with gross pay of at least €70,000.
Inbound researcher: people in qualifying research roles, with no minimum salary.
To qualify, you must not have been Belgian resident, or lived within 150 km of the border, in the previous 60 months. Your employer applies within three months of your start date. The regime lasts five years and can be extended by three.
The changes in the Law of 18 December 2025 are retroactive to 1 January 2025. Under Circular 2026/C/51, employers had to amend contracts by 1 July 2026 to apply them to 2025. For social security, the old rules still apply for now.

The new capital gains tax
Until 2026, private investors in Belgium generally paid no tax on gains on shares. That's changed. Under the law of 6 April 2026, published on 21 April 2026, gains on financial assets realised from 1 January 2026 are taxed at 10%:
the first €10,000 of gains each year is exempt, and unused exemption can build up by €1,000 a year to €15,000
it covers shares, bonds, funds, crypto and some insurance contracts
gains made before 1 January 2026 aren't taxed
if you move to Belgium from 2026, the value of your assets when you arrive counts as their cost
Speculative gains outside normal private investing are taxed at 33%. Separate, graduated rates apply to large shareholdings.

Investment income, pensions and wealth
Dividends and interest are generally taxed at 30%, withheld at source, with small exemptions for some savings interest and dividends. A tax of 0.15% a year applies to securities accounts worth more than €1 million. Foreign pensions are taxed at the progressive rates. Inheritance and gift tax are set by the regions (Flanders, Wallonia and Brussels) and can be high outside close-family reliefs.
Freelancing
Self-employed people pay income tax at the progressive rates plus the communal surcharge, and social contributions of around 20% of income, up to a ceiling. On €87,000 of profit, that comes to about 45% all-in.
Remote work
Belgium doesn't have a digital nomad visa. EU nationals can live and work freely. Non-EU nationals generally need a single permit sponsored by a Belgian employer, or a professional card if self-employed.
Double tax treaties
Does Belgium have double tax treaties? Yes, about 95, including with the UK, the US, the Netherlands, France, Germany, Luxembourg, Spain, Italy, Switzerland, Canada, Japan, China, India and the UAE.
