What is the difference between the pre-tax and Roth 457 plan?

Pre-tax 457 contributions are made before taxes are deducted from your paycheck. Your savings in the pre-tax 457 account, and any investment earnings on those assets, will grow tax-free until funds are withdrawn. Roth 457 contributions are made after taxes are deducted from your paycheck. Any savings in this account can be withdrawn tax-free (also known as a qualified distribution) if you are 59 ½ (disabled or deceased) and 5 years have passed since January 1 of the year of your first Roth contribution (including rollovers).
