Is the taxation of pension fund withdrawals at risk?

At its meeting today, the Federal Council defined the relief measures it intends to take from the report of the group of experts charged with reviewing tasks and subsidies. These measures include the abolition of favourable taxation on capital withdrawals from 2nd and 3rd pillar retirement provision.
For the record, pension capital is currently taxed at 1/5th of the rate at federal level and in most cantons. Eliminating this favourable tax rate could result in pensioners being taxed fivefold.
If adopted, such a measure would have considerable financial consequences for both policyholders and pension funds.
