CSRS employees are eligible to make voluntary contributions to the Civil Service Retirement and Disability Fund. Voluntary contributions may be used to increase the amount of annuity at retirement or as a savings or investment option. Voluntary contributions should not be confused with contributions to the Thrift Savings Plan.
Total voluntary contributions may not exceed 10 percent of the total basic pay an employee has received to date. If you have questions about the maximum amount you can contribute to a voluntary contribution account contact the Benefits Line and ask to speak to a retirement specialist.
Voluntary contributions earn a variable interest rate determined by the Treasury Department each calendar year, based on the average yield of new investments purchased by the CSRS fund during the previous fiscal year.
You can not make voluntary contributions if you owe a deposit for nondeduction civilian service or a redeposit for
refunded retirement deductions.
