Despite having enjoyed an exempt salary for many years, your pension will usually be subject to tax. The tax allowance and the tax adjustment or partial compensation will therefore also be included in the tax levy. Depending on the tax burden, income tax can amount to up to € 60,000 a year. It is also possible that the tax assessment is not made until 18 months later, so that tax is suddenly levied over a two-and-a-half-year period. This would require you to reserve a sum of €150,000.
Prevent this kind of unpleasant surprise and make sure you ask for a provisional assessment in good time! Moreover, this will prevent you having to pay a high rate of tax interest.
