How bonuses are actually taxed
A bonus is income from employment. It is added to your regular salary and taxed at the marginal rate that applies to that level of combined income. If your regular salary already puts you in the highest tax bracket, your bonus is taxed at the top rate. If your regular salary is in a lower bracket and the bonus pushes you over a threshold, the portion above the threshold is taxed at the higher rate.
The key principle: bonuses are not taxed at a special higher rate. They are taxed at the same rates as all other employment income. The confusion arises because employers must withhold income tax at the point of payment — and their withholding calculation often produces a higher-than-necessary deduction.
In the Netherlands, employers use the bijzondere beloningen (special remuneration) table to calculate withholding on bonuses, holiday pay (vakantiegeld) and year-end bonuses (dertiende maand). This table is designed conservatively to prevent under-withholding, which means employees often see a much larger deduction on their bonus payslip than they will ultimately owe.
Any over-withheld tax is returned through the annual tax return. The actual tax on a bonus is always the marginal rate on the income — which, critically, is always less than 100%, meaning you always net more cash from a bonus than the tax costs you. A bonus taxed at 49,5% leaves 50,5 cents in every euro net in your pocket.
Netherlands bijzondere beloningen — how it works
The bijzondere beloningen tabel is a withholding table specifically for one-off payments: annual bonuses, holiday allowances, performance payments, and commissions. The employer looks up the employee's regular annual salary in the table and finds the applicable withholding rate for a single large payment.
The table rates are deliberately set at conservative levels to prevent large tax debts at year-end. For an employee with a regular annual salary of 60.000 receiving a 10.000 bonus, the bijzondere beloningen table may specify withholding at 49,50% on the full 10.000 — even though the employee's actual marginal rate might be 36,97% for most of that amount.
This produces a 4.950 withholding on a 10.000 bonus. When the annual return is filed, the correct tax on the 10.000 is calculated based on the actual marginal rate: approximately 3.697. The difference of approximately 1.253 is refunded.
The practical consequence: employees receiving bonuses in the Netherlands should always file an annual tax return (aangifte) to reclaim overpaid tax from bijzondere beloningen withholding. The refund is automatic once the return is filed and processed.

Worked examples
Actual tax on bonus: 8.000 x 36,97% = 2.958. Net bonus: 8.000 - 2.958 = 5.042. However, the bijzondere beloningen table at 55.000 base salary may specify 49,50% withholding: 8.000 x 49,50% = 3.960. Overpayment: 3.960 - 2.958 = 1.002, refundable via annual tax return. The employee receives 4.040 on their payslip but should ultimately net 5.042 after return.
Salary of 72.000 leaves 75.518 - 72.000 = 3.518 remaining in bracket 1. First 3.518 of bonus: taxed at 36,97% = 1.300. Remaining 10.000 - 3.518 = 6.482: taxed at 49,50% = 3.209. Total tax on bonus: 4.509. Net bonus: 5.491. Employer will withhold using bijzondere beloningen table at possibly 49,50% on full 10.000 (4.950) — refund of approximately 441 via annual return.
Even at the highest marginal rate of 49,50%, a 20.000 bonus generates 10.100 in net income. There is no scenario in a standard tax system where receiving a bonus makes you worse off. 49,50% is the rate — you keep 50,50% of every euro. The confusion arises from withholding (which can be higher) being mistaken for the actual rate, and from mistakenly believing the rate applies to all income rather than just the bonus increment.
