Basically, if you retire in 2022, 82% of your pension will be taxed. For every year you retire later, 1% is added. So, for example, if you retire in 2030, you will have to pay tax on 90% of your pension. From the year 2040, 100% of your pension will be taxed. However, it is important to note that this taxation is only applied to pension benefits above the basic tax allowance, which (as of 2022) is €10,347 (€20,694 for married couples).
