You can enroll in Deferred Compensation or change your biweekly contribution amount at anytime in Workday. 

Deferred Compensation permits full-time and permanent part-time employees (working 20 or more hours per week), on a voluntary basis, to authorize a portion of salary to be withheld and invested for payment at a later date upon termination or retirement. You have two enrollment options, the Traditional 457 Plan and the Roth 457 Plan. Employees may enroll at any time during the year.

Under the Traditional 457 Plan neither the deferred amount nor earnings on the investments are subject to current federal or state income taxes. Taxes become payable when deferred income plus earnings are distributed, presumably during retirement when you are in a lower income tax bracket.

The Roth 457 Plan option provides an alternative to pre-tax investing. Roth contributions are considered “after-tax,” which means taxes are withheld when you contribute. However, qualified distributions on your contributions plus any earnings are completely tax-free. For example, if you contribute $100, the entire $100 comes out of your net pay, but when you make eligible withdrawals from your account, the entire amount plus any earnings are entirely tax-free.
