What is the tax aspect of the 2nd pillar?
Basically:
The contributions made by employees to the pension fund can be deducted from the direct taxes of the
Federal, cantonal and municipal deductions.
Pensions, i.e. benefits from the 2nd pillar, are taxable as income. Capital withdrawals, on the other hand, are taxed separately from other income at a privileged special rate.
Further applies:
An early withdrawal from the 2nd pillar for home ownership is taxed as a lump-sum withdrawal. If an early withdrawal is repaid, the tax paid at the time can be claimed back without interest.
With clever planning (staggered withdrawals spread over several tax years), you can often save several thousand francs in taxes.
