Belgium : Gross to Net Calculation
Asha MenonCommunity desk
Brussels · Belgium · 31 January 2024 · 3 min read
A Belgian gross salary tells you remarkably little about what lands in your account. Tax is steep, the benefits are unusually generous, and two offers with identical gross figures can differ by hundreds a month. Do not compare offers on gross — compare them on net plus what comes with it.
At a glance
Why there is no single answer
Belgian net pay depends on more than the salary. Marital status, number of dependent children, your region, a mobility budget and any net allowances all move the figure — which is why a colleague on the same gross can take home noticeably more or less than you.
The practical tool is the SD Worx gross-to-net calculator. Enter the gross, your region and your benefits and it gives you a realistic net. Run every offer through it before you respond to any of them.
Check the special tax regime before you calculate anything. If you have been recruited from abroad on €75,000 or more, 30% of your gross may be treated as non-taxable — worth around €1,000 a month on a €100,000 salary, which dwarfs anything you will negotiate on the gross figure. See the special tax regime, and note it has a three-month application deadline.
The benefits that actually move the number
- Company car or mobility budget. Common above a certain level and worth a great deal net, because it is taxed far more favourably than the equivalent salary. If you were going to own a car anyway, this is often the largest single item in a package.
- Meal vouchers — typically €140–150 a month, usable in supermarkets. Effectively tax-free money for something you were going to buy regardless.
- Eco-cheques — up to €250 a year, for a defined list of environmentally friendly goods.
- Hospitalisation and group insurance — standard in many packages, and worth checking before you buy your own; see mandatory health insurance.
- Home-working allowance, net expense allowances, gym memberships. Small individually, not small together. Ask HR for the full list — they will not always volunteer it.
Do not convert your old salary and compare
It is the commonest mistake people make with a Belgian offer, in both directions. The gross looks poor against what you earned elsewhere; the benefits, the 13th month, the holiday pay and the six weeks of leave are not in that number at all. Compare net-plus-package against net-plus-package, or you will misjudge the offer.
Rough salary landscape
Broad indications rather than benchmarks — experience, sector and city all move these:
- Tech and finance — senior roles beyond €70,000; software engineers averaging around €65,000 after five years or so.
- Healthcare — specialists in the €70,000–€80,000 range.

What to ask before you accept
- Is it 13.92 months, or 12? The Belgian convention includes holiday pay and a thirteenth month — confirm which the quoted figure is.
- Meal voucher value, and the employer/employee split.
- Company car or mobility budget, and at what level it applies.
- Hospitalisation and pension contributions.
- Has the special tax regime been applied for?
