How to pay an employee a bonus that is 50% income-tax free, within the raised 2025 caps (7.5% of profit, 30% of gross pay), without forgetting social contributions or the filing with the tax office: the employer's guide.
In short. The profit-sharing bonus (prime participative) is a bonus you pay an employee, half of which escapes income tax. Two caps frame it, both raised on 1 January 2025: the total envelope cannot exceed 7.5% of the previous year's result, and one employee's bonus cannot exceed 30% of their gross annual pay. Watch the trap: the 50% exemption applies to income tax only. The bonus stays subject to social contributions on its full amount.
Want to reward a team member without half the bonus disappearing into tax? Luxembourg has had a tool built for exactly that since the 2021 reform: the profit-sharing bonus. It lets an employer pay an employee a bonus of which 50% is exempt from income tax, at the employer's discretion, with no collective bargaining involved. The catch is that you have to respect two caps, keep proper books and declare the bonus correctly. Here is how to pay it without slipping up, with the figures current for 2026.
What is the profit-sharing bonus?
The profit-sharing bonus is a tax mechanism set out in article 115, point 13a of the income tax law. The principle is simple: when an employer pays this bonus to an employee, half of the amount is exempt from income tax, the other half being taxed normally. The employer decides whether to grant it, to whom and for how much, without having to write it into a collective agreement or pay it to everyone. You can reward one specific employee for one specific year.
On the company side, the bonus is a staff cost like any other, deductible from taxable profit. So you lower your tax base by rewarding your people, while the employee pockets a bonus half of which is tax-free. It is this double effect that makes the scheme attractive, provided you stay within the rules.
The two caps to respect (raised in 2025)
The whole mechanism rests on two limits, one at company level, the other at employee level. The tax package that took effect on 1 January 2025 raised both.
| Cap | Since 1 January 2025 | Previously |
|---|---|---|
| Company's total envelope | 7.5% of the previous year's positive result | 5% |
| Maximum bonus per employee | 30% of their gross annual pay | 25% |
The first cap limits the total effort: the sum of all profit-sharing bonuses paid in a year cannot exceed 7.5% of the positive result of the operating year immediately preceding. That result is not an estimate: it is the profit shown in account 142 of the standard chart of accounts, after tax for a commercial company. In other words, no profit last year means no envelope this year.
The second cap protects the spirit of the scheme: for a given employee, the exempt portion only applies if the bonus stays under 30% of their gross annual pay, before benefits in cash and in kind. Anything above that is taxed as ordinary non-recurring income. A well-sized bonus therefore respects both limits at once.
The conditions to meet
The exemption is not automatic. It means ticking several boxes, some of which fall squarely on the bookkeeping.
- Proper accounting, kept both in the year the bonus is granted and in the preceding year. This is the condition that catches young structures out: without compliant books for the reference year, the 7.5% envelope cannot be calculated.
- A profit of a commercial, agricultural or liberal-profession nature in the reference year.
- An employee affiliated to a mandatory social security scheme, Luxembourg or covered by a bilateral or multilateral instrument.
- A nominative list of beneficiaries and amounts, sent to the competent RTS office of the Direct Tax Administration, with the elements that prove the conditions are met.
- A clear entry for the bonus in the payroll book and on the pay certificate (model 160), under an unambiguous label such as "prime participative exemptée".
The 50% exemption is applied at source, on the payslip, at the moment of payment. The employee has nothing to do: the employer applies the withholding correctly, then files.
The point everyone forgets: social contributions
This is the most common mistake, and it turns into broken promises. The profit-sharing bonus is not "100% tax-free". The half-exemption concerns income tax only. For social security purposes, the bonus remains employment income: it falls into the base for social contributions on its full amount, employee share and employer share alike. So the employee's contributions are calculated on 100% of the bonus, even though only half is taxed.
In practice, presenting the profit-sharing bonus as a gift free of tax and charges is setting up a disappointment on payday. The right message is more accurate and just as appealing: for the same budget, the employee keeps more than with an ordinary bonus, because half escapes income tax. We break down how to read a payslip, contributions included, in our article on going from gross to net in Luxembourg, and how contributions work in our piece on social contributions.
Want to reward a team without getting the cap or the filing wrong? We size the bonus with you, on your real figures.
Size a profit-sharing bonusA worked example
Take an employee whose gross annual pay is 48,000 €. Their individual cap is 30%, meaning 14,400 € of eligible profit-sharing bonus at most. Say you decide to pay them a bonus of 4,000 €, and that your company earned enough last year to cover that sum within the 7.5% envelope.
| Step | Ordinary bonus | Profit-sharing bonus |
|---|---|---|
| Gross amount paid | 4,000 € | 4,000 € |
| Income-tax base | 4,000 € | 2,000 € |
| Social contribution base | 4,000 € | 4,000 € |
The difference plays out on income tax. At a marginal rate of around 40%, exempting the 2,000 € is worth close to 800 € of tax saved for the employee, at identical cost to the employer. Contributions, meanwhile, are due on the 4,000 € in both cases. The gain is real, but it comes from tax, not from charges: that is exactly what to tell the employee to avoid any misunderstanding. The figures above are an illustration; the real marginal rate depends on the employee's personal situation and tax card.
Bonus, salary or dividend: when the bonus makes sense
The profit-sharing bonus is not a substitute for salary, it is an occasional top-up. It shines when you want to reward a good year or a specific contribution without raising the wage bill for good. For a director wondering instead how to pay themselves, the trade-off sits elsewhere, between salary and dividends, as we explain in our article on how to pay yourself as a SARL manager.
One point of caution here: the profit-sharing bonus targets employees. A majority owner-manager, treated as a self-employed worker because they hold the business permit and more than 25% of the shares, is not an employee affiliated as such, and so falls outside the scheme for their own pay. Before planning a bonus for a director, check their social status, or you will build an exemption that will not hold.
Who this scheme is not for
Let us be plain. The profit-sharing bonus assumes three things that are not always in place. Without a profit last year, there is no envelope, and a company that is starting up or coming out of a loss-making year cannot use it that year. Without proper accounting for the reference year, the basic condition is not met. And for a cross-border employee, the Luxembourg exemption says nothing about the treatment in their country of residence, where the bonus may be handled differently: this calls for a dedicated review rather than a blanket promise. Finally, the bonus does not replace a structured pay policy; it is a reward lever, not a trick to cut salaries.
How we handle this at Advena
Payroll and tax support are part of our fixed fee, from 325 € per month, all in. On the profit-sharing bonus, the coupling between the bookkeeping and the management tool changes three concrete things. First, we know your previous year's result in real time, in the Odoo where we keep your books, so we can tell you at once how large a 7.5% envelope you can commit. Second, we size each bonus under the individual 30% cap and apply the half-exemption directly on the payslip, contributions included. Third, we prepare the nominative list for the RTS office and the entry on the pay certificate, so the exemption holds up under audit. The wider framework of this support is set out in our guide to accounting firms in Luxembourg, with the price in our article on what an accounting firm costs.
We inform on the rule and apply it for you; we do not replace tailored advice on a specific situation, especially for a director or a cross-border worker whose status needs a separate review.
Frequently asked questions
Is the profit-sharing bonus really 100% tax-free?
No. Only half of the bonus is exempt from income tax; the other half is taxed normally. And the exemption covers income tax only: the bonus stays subject to social contributions on its full amount. Calling it a bonus "free of tax and charges" is therefore inaccurate.
What are the caps on the profit-sharing bonus in 2026?
Two caps apply since 1 January 2025. All bonuses paid by the company cannot exceed 7.5% of the previous year's positive result. And one employee's bonus cannot exceed 30% of their gross annual pay, before benefits in cash and in kind. Previously these limits were 5% and 25%.
Is the profit-sharing bonus subject to social contributions?
Yes. The 50% exemption applies to income tax only. For social security purposes the bonus is employment income and falls into the contribution base on its full amount, employee share and employer share alike.
Can a company director receive a profit-sharing bonus?
The scheme targets employees affiliated to a mandatory social security scheme. A majority owner-manager, treated as a self-employed worker because they hold the business permit and more than 25% of the shares, does not fall within it for their own pay. Their social status must be checked case by case.
How do you declare the profit-sharing bonus to the authorities?
The employer applies the half-exemption at source on the payslip, records the bonus on the pay certificate (model 160) and sends the competent RTS office a nominative list of beneficiaries and amounts, with the elements proving the conditions are met.
