The CalPERS 457 Plan is a voluntary deferred retirement savings plan that allows you to defer any amount, subject to annual limits, from your paycheck on a pre-tax and/or Roth after-tax basis.
Receiving your deferred compensation in installments over several years can reduce your tax bill, because the smaller installment payments will typically be taxed at a lower rate than a larger lump-sum payment will be.
