Are there restrictions for a member purchasing service credit on a tax-deferred plan?
Yes. Restrictions apply to a member on a tax-deferred plan that do not apply to a member on an after-tax plan. Under a tax-deferred plan, a member cannot: Stop or change payments until the credit is fully purchased or employment is terminated, Make lump-sum payments for the same service being purchased, or Stop payments to pay off the remaining balance in a lump sum.
