You need to check with your employer or retirement plan administrator to get an answer to this question. Ask for details about your 401(k) plan in writing. Before age 59½, you will probably not be able to do a rollover of 401(k) assets to an IRA unless there is a voluntary or involuntary separation (i.e., you decide to leave the employer for a new job or to retire or you are laid off). However, many plans will allow 401(k) rollovers after a specific age (e.g., 60 or 65) while you are still working. Again, check with your plan administrator for rules specific to your 401(k).
