📊 Tax impact breakdown of variable pay
The Variable Salary & Annual Bonus Calculator helps you estimate exactly how much of your commissions, incentives, or year-end bonuses you get to keep after taxes in Spain. Adding variable pay to your annual base salary moves you up the progressive tax brackets, often raising the withholding rate applied to your entire salary.
🔍 Why are bonuses taxed so heavily?
In Spain, annual bonuses and sales commissions are treated as standard earned income under the IRPF system. Because the IRPF is a progressive tax, introducing a bonus increases your total annual taxable base, pushing you into higher tax brackets and increasing the withholding rate on both your base salary and your variable pay. Additionally, unless your monthly earnings already exceed the statutory maximum contribution cap (€4,720.50 per month), your bonus is subject to Social Security contributions.
