Daniel P. Randolph, EsqIf you leave your company, what happens to your retirement assets?  Moving your assets into a rollover IRA can help you keep the same tax deferral benefits and you gain more control of your investments.  It’s definitely an option worth exploring with your financial advisor, but it isn’t the only road you can take.
 
You can also stay in your employer’s 401(k) plan, or if you will be moving to a new company, you can move your funds to a new plan.  You can also cash out your 401(k), but you may face serious tax consequences depending on their use and if you have not reached age 59-1/2, so it is best to talk to a tax advisor before a decision is made.
