401(k) retirement plan features and withdrawal regulations

Employer-sponsored 401(k) plans offer various features and withdrawal options that are governed by both federal law and specific plan rules.

One option for employers is the addition of a Roth feature. Unlike traditional 401(k) contributions, Roth contributions are made on an after-tax basis. While this requires plans to maintain separate accounts, it allows for qualified distributions—typically occurring after age 59½ and a five-year waiting period—to be free of federal income tax. This can serve as a hedge against higher future tax rates, though it may be less advantageous if a participant's tax rate is lower during retirement.

Regarding access to funds, employees may be able to withdraw money while still working through in-service withdrawals, hardship withdrawals, or 401(k) loans. In-service withdrawals are often restricted to those age 59½ or older, depending on the plan. Hardship withdrawals must be for immediate and serious financial needs and generally cannot be repaid. 401(k) loans allow participants to borrow up to 50% of their vested balance or $50,000, whichever is less, provided they are repaid according to schedule to avoid being treated as a taxable distribution.
