Payroll Services in Belgium

The headline employer rate is 25.00%, and it is not the whole bill. Since the tax shift completed on 1 January 2018 the rate for the private profit sector has been 25.00%, made up of a 19.88% basic contribution and 5.12% wage moderation. On top sit smaller levies, most of them with wage moderation added: 1.69% of unemployment contribution for employers with ten or more employees, 0.34% to the Closure Fund below twenty employees and 0.39% from twenty, 0.10% for temporary unemployment, 0.10% for risk-group training, 0.05% for childcare and, for the first three quarters of 2026, 0.01% for the Asbestos Fund. A realistic all-in figure for a white-collar employee is about 27.3% of pay at a company with twenty or more employees and about 25.6% below ten, before anything the joint committee adds.

Blue-collar employees are more expensive for a structural reason. Their holiday pay is paid by a State fund rather than by the employer, so the employer funds it through contributions instead: a 5.57% quarterly holiday contribution, which is why the blue-collar headline is 30.57%, and a 10.27% annual one. Both, like every other contribution for arbeiders / ouvriers, are charged on gross pay multiplied by 108%, and the employee’s 13.07% is charged on the same 108% base. A blue-collar cost model built on a white-collar template understates by 8% before any rate is applied.

There is now a ceiling, which is new and which many guides have not caught up with. From 1 July 2025 the 25.00% is no longer due on quarterly pay above a threshold, set at EUR 85,000 per quarter at introduction and indexed with the pivot index to EUR 86,700 from 1 January 2026 and EUR 88,434 from 1 July 2026. Only the 25.00% is capped: the other employer levies and the employee’s 13.07% stay due on the full salary. In practice it only touches very high salaries, but it is the first structural break in a historically uncapped system.

Reductions run the other way, and the one small employers rely on most changed in mid-2026. The first-hire target-group reduction was cut from EUR 3,100 to EUR 2,000 per quarter on 1 July 2026, and the cut also applies to reductions that were already running – so an employer claiming it saw its quarterly cost rise by EUR 1,100 without doing anything. The structural reduction continues to lower contributions on low wages.

A Belgian white-collar employer in PC 200 pays about 13.92 months of salary a year, and none of it is a bonus. Twelve monthly salaries, plus double holiday pay at 92% of a month’s gross paid in May or June, plus an end-of-year premium of one full month paid in December, plus a separate annual premium of EUR 330.84 paid in June. That is roughly 16% more cash than twelve monthly salaries, and a budget built on twelve months plus on-costs is wrong by that margin from the first day. The one mercy is that double holiday pay carries no employer social security: the RSZ collects only a 13.07% employee contribution on most of it.

Blue-collar holiday pay is not a variation on that. It is a different system with a different payer. An arbeider / ouvrier receives no holiday pay from the employer. The Rijksdienst voor Jaarlijkse Vakantie / Office National des Vacances Annuelles, or a sectoral holiday fund, pays the worker directly – 15.38% of the previous year’s gross wages at 108%, being 8% single and 7.38% double holiday pay, paid around May.

The employer funds that through contributions of 15.84% in total, both on wages at 108%: 5.57% charged quarterly with the DmfA, and 10.27% charged once a year, due on 31 March and payable by 30 April. The practical consequence is that the two populations spike in different months. A white-collar employer braces for May and June. A blue-collar employer has no May spike, but takes an April hit when the annual holiday contribution lands. A mixed workforce provisions for one and is ambushed by the other.

Statutory leave is 20 days on a five-day week, earned in the preceding calendar year – so a new entrant has no paid Belgian entitlement in their first year beyond what supplementary European leave provides.

Belgian wages rise automatically by law, and the rate is not yours to set. Belgium is one of very few countries that keep statutory automatic wage indexation. The driver is the smoothed health index – consumer prices excluding tobacco, alcohol, petrol and diesel, averaged over four months. Indexation is imposed by the sectoral collective agreement, which is generally rendered universally binding by Royal Decree, so breaching it is an offence under the Social Criminal Code rather than a commercial dispute.

There is no single national rule. Each joint committee sets its own mechanism and date, and they genuinely differ. PC 200, the largest with more than half a million employees, indexed by 2.21% on 1 January 2026, on both the sectoral scales and actual salaries. PC 111 and PC 209, covering about 170,000 metal-sector workers, index on 1 July and moved 2.81% in 2026. PC 124 in construction indexes quarterly. And committees such as PC 202 in retail food move by a fixed percentage whenever the pivot index is crossed, on no fixed date at all – the last crossing was in June 2026 and the next is forecast for December 2026.

The centenindex is the 2026 change few people outside Belgium have priced. Introduced by the Programme Act of 30 May 2026 and in force from 1 June 2026, it moderates indexation in euro terms rather than suspending it. An employee on up to EUR 4,000 gross a month, pro rata for part-timers, is unaffected. Above EUR 4,000 the increase is limited to the euro amount a EUR 4,000 earner receives – so on a 2% index a EUR 5,000 earner gets EUR 80 rather than EUR 100 – and half of the employer’s saving must be paid to the RSZ as a special wage moderation contribution. It applies to the first 2% of indexation in each sector from 1 June 2026, so it reached the metal sector on 1 July 2026 but only reaches PC 200 on 1 January 2027, and a second 2% round is planned for around 2028.

Say plainly what has not happened, because it is widely misreported. Automatic indexation has not been suspended, frozen or skipped. Separately, the wage norm caps negotiated increases at 0% for 2025 and 2026 – but indexation and sectoral scale increases sit outside the norm and are always due. In practice indexation is the only pay rise most Belgian employees receive, and an employer who withholds it is both non-compliant and conspicuously so.

Meal vouchers went from EUR 8 to EUR 10 on 1 January 2026, and the increase is not automatic. The maximum employer share rose from EUR 6.91 to EUR 8.91 per working day, exempt from social security and income tax, with the employee’s minimum share unchanged at EUR 1.09. Corporate tax deductibility doubled from EUR 2 to EUR 4 per voucher, but only where the employer pays the full EUR 8.91. The increase needs a sectoral agreement, a company agreement or an individual contract amendment: an employer that simply raised the value in its payroll system has an exposure, not a benefit.

Eco-cheques are exempt from contributions and income tax up to EUR 250 per employee per year, must be granted by collective agreement or, where there is none, by individual written agreement, and cannot replace existing pay. The bicycle allowance is effectively compulsory across the private sector: CAO 164 applies as a safety net wherever the sector has no scheme of its own, at EUR 0.30 per kilometre from 1 January 2026 for up to 40 kilometres a day, with a tax-exempt maximum of EUR 0.37 per kilometre and an annual exempt ceiling of EUR 3,700.

The company car is a near-universal part of a Belgian white-collar package, and the tax rules turned decisively against fossil fuel on 1 January 2026. A petrol or diesel car ordered from that date is not tax-deductible at all; one ordered between 1 July 2023 and the end of 2025 is 50% deductible in 2026, falling to 25% in 2027 and nothing from 2028. Zero-emission cars remain fully deductible for now, and plug-in hybrids run under a separate transitional regime. On top, the employer pays a monthly CO2 solidarity contribution to the RSZ for every car made available for private use.

The tax-efficient collective bonus is the CAO 90 bonus. The 2026 ceilings are EUR 4,255 gross for social security and EUR 3,701 for tax, with a 33% employer contribution and 13.07% from the employee – on the maximum that leaves about EUR 3,700 net, far more than a classic bonus of the same cost. It is not a discretionary individual bonus: it must be tied to collective targets that are objectively measurable and genuinely uncertain when the plan is filed, over a reference period of at least three months. Since 1 June 2026, plans adopted by accession act – the route for companies without a union delegation – must be prepared and filed online through bonusplannen.be.

Notice in Belgium runs in weeks and starts on the Monday following notification, and when the employer gives it, it must go by registered letter or bailiff’s writ. Since the single status of 1 January 2014, blue- and white-collar periods are harmonised. The ladder runs from one week below three months’ service to 33 weeks at ten years, 48 at fifteen and 60 in the twentieth year, then roughly one more week per year. Employee resignation notice is about half, capped at 13 weeks.

Two reforms landed in 2026 and both apply only to new contracts, which means a Belgian payroll now tracks three regimes at once. For contracts starting on or after 1 June 2026, employer notice is capped at 52 weeks, which matters from about seventeen years’ service. For contracts starting on or after 1 August 2026, notice in the first six months is a uniform one week for both sides – functionally a trial period under another name. Existing contracts keep the uncapped ladder, and anyone in service before 1 January 2014 still carries a two-part calculation with the pre-2014 block frozen at its 31 December 2013 value.

Severance in lieu is calculated on the full package, not on salary. The indemnity equals the remuneration for the notice period that should have been served, on current pay plus contractual benefits: company car, meal vouchers, group and hospitalisation insurance, averaged bonuses, and the pro-rata end-of-year premium and double holiday pay. In a market where the company car is standard, the car alone moves the number materially. Where notice or indemnity reaches 30 weeks, outplacement is owed – 60 hours, valued at one twelfth of the previous year’s gross with a EUR 1,800 floor and a EUR 5,500 ceiling – and the indemnity is reduced by four weeks whether or not the employee accepts it.

Two procedural rules carry real risk. CAO 109 gives the employee the right to know the concrete reasons for dismissal: failing to give them costs a civil fine of two weeks’ pay, and a manifestly unreasonable dismissal attracts compensation of between three and seventeen weeks’ pay. And collective redundancy triggers the Renault procedure – notification of an intention rather than a decision, consultation of the works council, a substantive response to counter-proposals and a waiting period before any dismissal may be given. It is one of the few areas of Belgian law where a procedural defect can undo the terminations themselves.
