Penalty-free 401(k) distributions typically begin at age 59 1/2, although those who terminate employment at age 55 or over can also take 401(k) withdrawals without penalty, according to About.com.

Military personnel called from reserve to active duty for 180 days or more can also take penalty-free distributions.
Account holders of 401(k) plans must initiate required minimum distributions by age 70 1/2 or face a 50 percent penalty tax on the amount that should have been withdrawn, according to the IRS. The first distribution must be made by April 1 of the year after the account holder turns 70 1/2.
