How are taxes calculated?
Taxes are deducted from your winnings at the time the payout is processed into your bank account, excluding a tax-free amount of 3,000€. The remaining amount up to 62,800€ is taxed at a rate of 23% but a tax rate of 31% applies to the part of the winnings exceeding the amount of 62,800€. In this case, the amount that exceeds 62,800€ is taxed at 31%, and the amount above 3,000€ is taxed at 23%.
Do I have to pay income tax on my winnings myself?
Suppose during a calendar year the player receives more than 3,000€ in separate transactions, each of which does not exceed 3,000€. In that case, the player is obliged to submit an annual income declaration and individually pay the tax on the total amount of winnings over 3,000€.
