How much does it really cost to hire in Belgium in 2026?
Belgium charges 27% in employer NSSO/RSZ social security contributions, and pension is already inside that number. Add 20 days days of paid leave, 10 public holidays, and a notice cap that hits 52 weeks under new rules from 1 July 2026. A Belgian hire lands at 127 to 135 percent of gross salary once every line is counted.

The employer NSSO/RSZ social security rate in Belgium is 27%. Pension is already inside that figure. There is no separate occupational pension contribution on top for most private-sector employers.
Every employee gets 20 days paid leave days and 10 public holidays. The employer pays full salary for the first 30 days days of any illness.
The result is a total employer cost that runs 127 to 135 percent of gross salary for most Belgian hires. The exact figure depends on the salary level and any sector-specific contributions that apply in your industry.
The headline: what a Belgium hire actually costs
Start with the gross salary. Add 27% NSSO/RSZ social security on top. That single contribution covers health, unemployment, workplace accidents, and pension for the employee.
The table below shows illustrative totals at a EUR 60,000 annual salary. These are computed from verified statutory rates and labelled illustrative. They are not statutory figures.
The main cost components for a Belgium hire are public and fixed. The 27% NSSO/RSZ rate applies to gross remuneration with no ceiling. Higher salaries cost proportionally more. The illustrative example below uses a EUR 60,000 gross salary to show how the lines add up.
| Line | Illustrative cost on EUR 60,000 salary | Source |
|---|---|---|
| Gross salary | EUR 60,000 | Contract |
| Employer NSSO/RSZ at 27% on gross | EUR 16,200 (illustrative) | Settling in Belgium: social security contributions |
| Annual leave: 20 days paid days built into gross salary | Included in salary | Federal Public Service Employment |
| Public holidays: 10 days per year | Included in salary | Settling in Belgium: leave |
| Employer sick pay: 30 days days at 100% salary (white-collar) | ~EUR 500 reserve (illustrative; most absences are short) | Law of 3 July 1978, Art. 70-72 |
| Notice period reserve (context-dependent; built into exit cost model) | See termination section | Law of 26 December 2013 |
| Total illustrative employer cost | ~EUR 76,700 before the Teamed fee | ~128% of gross (illustrative) |
These figures are illustrative. They are computed from the 27% verified NSSO/RSZ rate. They are not statutory figures and will vary with actual salary, sector-specific levies, and benefits provided.
Add Teamed from $599 per employee per month and the total rises to around 134 to 137 percent of gross at a EUR 60,000 salary point. Use the Employer Cost Calculator to run your own salary figures.
-
Start with gross salary
Fix the agreed gross annual salary. Check it clears the guaranteed minimum monthly income floor. This is the base every other line builds on.
-
Add employer NSSO/RSZ contributions
Apply the employer social security rate to the full gross salary. There is no ceiling. Higher salaries cost proportionally more. Pension is already inside this rate for most employers.
-
Check for sector CAO supplements
Confirm which joint committee applies to your hire. Some sectors require group insurance or end-of-year premiums on top of the base NSSO/RSZ rate. These vary by sector and can be material.
-
Layer in statutory leave costs
Leave days and public holidays are built into the salary cost. Budget separately for the employer-funded sick pay period, which runs at full salary for the first days of each absence.
-
Model the notice period reserve
Notice periods in Belgium scale with tenure and are the basis for exit indemnity. Include the potential notice cost in any scenario model from the point of hire, not the point of exit.
Employer NSSO/RSZ: the biggest line, with pension already inside
Employer NSSO/RSZ social security in Belgium is 27% on gross remuneration. There is no cap.
Unlike most European markets, Belgium does not separate out occupational pension as a second employer contribution. Pension is funded through the NSSO/RSZ system itself. The 27% is the complete employer social contribution for most private-sector white-collar roles.
Employer NSSO/RSZ contributions cover health insurance, unemployment, workplace accident insurance, family allowances, annual holidays, and pension. The basic employer rate for white-collar workers is approximately 27% of gross remuneration.

No separate pension contribution for most employers
Many European markets require a separate mandatory occupational pension contribution on top of social security. Belgium does not. The pension component is built into the 27% NSSO/RSZ rate. Unless a sector collective agreement (CAO/CCT) requires a supplementary group insurance contribution, there is no additional pension line for most private-sector employers.
Sector CAOs in Belgium do sometimes require group insurance (groepsverzekering/assurance groupe) contributions, which are additional. These are set at sector or company level and vary widely. Check your sector classification before budgeting.
Employee NSSO/RSZ contribution
The employee also pays NSSO/RSZ at 13.07% of gross salary, with no cap. This reduces the employee's net pay but is not an additional employer cost. Employers withhold it and remit it alongside the employer contribution each quarter.
Minimum wage reference
The guaranteed average minimum monthly income (GMMI) in Belgium is €2,189.81/month from 1 April 2026. All employment contracts must clear this floor. The NSSO/RSZ contribution applies to gross pay above this level too, so a minimum-wage hire still attracts the full 27% employer rate.
Progressive income tax: what it means for your payroll obligation
Belgium's income tax is progressive. The top rate is 50% on income above EUR 51,070.
The employer withholds and remits prepayment tax (bedrijfsvoorheffing/precompte professionnel) each month. This is not an employer cost. It comes out of the employee's gross salary. But getting the withholding right matters.
The four income tax bands for tax year 2026
Belgium uses four brackets for the 2026 tax year (assessment year 2027), confirmed by FPS Finance Belgium:
| Income band | Tax rate |
|---|---|
| €0/year to €16,720/year | 25% |
| €16,720/year to €29,510/year | 40% |
| €29,510/year to €51,070/year | 45% |
| Above €51,070/year | 50% |
Basic personal exemption
Every taxpayer gets a basic personal exemption of €11,180/year for tax year 2026. This amount is taxed at the lowest bracket rate rather than being fully exempt, so it provides a partial tax reduction rather than a zero-rate band. Additional exemptions apply for dependants.
Why this matters for the employer
Belgium's progressive structure means your withholding calculation has more steps than a flat-rate market. The monthly prepayment tables are published by FPS Finance. Errors in withholding create reconciliation issues at year-end that fall on the employee. Running payroll through a specialist or an EOR like Teamed avoids this risk.
Net-to-gross ratio at different salary levels (illustrative)
At a EUR 60,000 gross salary, the combined employee NSSO/RSZ of 13.07% and the progressive income tax reduce take-home pay to roughly 50 to 55 percent of gross after all deductions (illustrative). Belgian employees often negotiate on net salary expectations rather than gross. This can create confusion at offer stage. Always confirm whether a candidate's expectation is gross or net.
Statutory leave: the cost most buyers miss
Every Belgian employee gets 20 days paid leave days per year plus 10 public holidays. Both are non-negotiable from day one.
Sick pay is a real employer cost. You pay full salary for the first 30 days days of each illness for white-collar workers. After that, state health insurance takes over.
Annual leave
Belgium calculates annual leave on the basis of days worked in the prior year. For a white-collar worker with a full year of service, the entitlement is 20 days days under the Royal Decree of 30 March 1967. The entitlement is built into the gross salary cost. It does not create a separate line on the payroll.
Public holidays
There are 10 public holidays per year under the Law of 4 January 1974. Employees who work on a public holiday are entitled to a substitute day off and a supplement. Budget for this if your operation runs on public holidays.
Employer sick pay: the guaranteed remuneration period
When a white-collar employee is off sick, you pay 100 percent of salary for the first 30 days days. There is no waiting period. This applies to each illness episode, not just the first of the year. After the 30 days-day employer period, the national health insurance fund (mutualiteit/mutualite) takes over at a lower replacement rate.
For most employees, short illnesses of a few days are the norm. The 30 days-day exposure is real but averages modestly across a team. A serious illness that runs beyond 30 days shifts to state cover. Long-term sick leave from 1 January 2026 triggers new re-integration obligations under the Partena Professional guidance, requiring the employer to prepare a return-to-work plan.
Parental and family leave
Maternity leave runs for 15 weeks. Birth leave for co-parents is 20 days. Each parent is entitled to 4 months of full-time parental leave (or its part-time equivalent) under CBA No. 64. These are partly state-funded. The employer's main cost is administration and managing absence cover.

Frequently asked questions
What does it cost to hire someone in Belgium in 2026?
A Belgium hire typically costs 127 to 135 percent of gross salary once employer NSSO/RSZ social security is included. The employer NSSO/RSZ rate is 27% on the full gross salary with no ceiling. Pension is bundled inside that rate for most private-sector employers. Annual leave of 20 days days and 10 public holidays are built into the salary cost. Sector CAO supplements may add further.
What is the employer social security rate in Belgium in 2026?
The employer NSSO/RSZ rate for white-collar workers is approximately 27% of gross remuneration. There is no upper ceiling. The rate covers health insurance, unemployment, workplace accident insurance, family allowances, annual holidays, and pension. Unlike many European markets, Belgium does not require a separate occupational pension contribution for most private-sector employers. The pension component is part of the 27% NSSO/RSZ rate.
How does Belgian sick pay work for employers?
White-collar employees in Belgium receive 100 percent of salary from the employer for the first 30 days days of illness. There are no waiting days. After the employer-funded period, the national health insurance fund covers the employee at a lower rate. The 30 days-day obligation applies to each illness episode. Long-term illness from 1 January 2026 triggers re-integration obligations for the employer.
What is the notice period cap in Belgium from 2026?
From 1 July 2026, the maximum employer notice period for new employment contracts is capped at 52 weeks. This cap applies after 17 years of service with the same employer. The notice period is also the basis for indemnity in lieu of notice. For a long-serving employee, this represents approximately 12 months of salary as the maximum exit indemnity under the new cap.
What statutory leave must a Belgium employer provide?
Every Belgian employee is entitled to 20 days paid leave days per year plus 10 public holidays. The 20 days days are set by the Royal Decree of 30 March 1967. Maternity leave is 15 weeks. Birth leave for co-parents is 20 days. Each parent has a right to 4 months of full-time parental leave under CBA No. 64.
The most common Belgium cost mistake we see is treating the NSSO/RSZ rate as the only employer contribution and stopping there. For most sectors that is correct. But the sector CAO can add a group insurance line that nobody flagged at the budgeting stage. The joint committee check takes five minutes and can save thousands in surprises.
Belgium's employer NSSO/RSZ rate is 27%, and pension is already inside that number.
Add 20 days leave days, 10 public holidays, and an employer sick pay obligation from day one.
A Belgian hire consistently runs above 125 percent of gross. Know every line before you send the offer.
