Signing bonus

What it means

A signing bonus is a one-off payment an employer makes to a new hire on joining, to attract them to a hard-to-fill position. It is used mainly in sectors with labour shortages, such as IT, manufacturing, healthcare or accounting during tax season.

The bonus is part of the employee's taxable income. It is included in gross pay for the month it is paid, and tax advances as well as social and health contributions for both employee and employer are due on it. The total cost to the company is therefore higher than the amount paid out.

Unlike some employee benefits, which may be tax-exempt up to a limit, a signing bonus carries no special tax advantage. Its strength is simplicity and an immediate effect when a candidate is choosing between several offers.

How it works in practice

The terms of the bonus are set out in the employment contract or a separate agreement: the amount, when it is paid and possibly a requirement that the employee stays for a certain time. The bonus is often paid only after the probation period or in two instalments.

If the contract links the bonus to staying and the employee leaves early, the employer may ask for it back. It may deduct the amount from pay only under a written wage deduction agreement and within the rules on payroll deductions; otherwise it must pursue the claim as an ordinary debt.

In the books the bonus is part of personnel costs. For larger amounts, consider whether it is better to spread it over salary or combine it with tax-favoured benefits, comparing the total cost to the company and the employee's net income.

What to watch out for

A clawback clause must be clear and proportionate. A court may regard overly strict terms, such as repaying the whole amount on leaving after several years, as a disproportionate restriction on the employee. A pro rata repayment based on the time remaining until the agreed date is a reasonable approach.

Equal treatment also applies to signing bonuses. If a company offers a bonus only to some candidates for the same position, it should have objective reasons, such as qualifications or urgency of the hire, to avoid the appearance of discrimination.
