Additional pension savings, sometimes called private pension savings or 4/2% savings, is an optional form of saving in addition to mandatory contributions to a pension fund, where the employee pays 2% or 4% and the employer pays a 2% contribution. Withdrawing these savings does not affect the old-age pension allowance from TR, with one exception: those who receive supplementary allowances for people with limited old-age pension rights must specify payments from additional pension savings in their income plan, as the amount of the supplementary support is income-related and all income affects its calculation.
