Your contributions and all the interest you receive from your account are subject to federal income tax (with exception of any contributions made prior to January 12, 1988). When processing a refund of retirement contributions, the Retirement Office is required to withhold 20% of the taxable portion of your refund for federal tax. The 20% tax payment is required only if the refund is made directly to the member. To defer tax payments, you must make a direct rollover of your retirement funds to an Individual Retirement Account, (IRA) or another type of retirement account with a financial institution. With a direct rollover, no tax is withheld and the entire taxable portion of your refund is transferred. If you have both taxable and nontaxable contributions, you may accept receipt of the nontaxable portion of your refund without tax consequence and the taxable portion may be rolled over.
