The term IRA Rollover refers to the process of transferring money from a retirement plan like a 401(k) to an IRA (Individual Retirement Account).

When you leave a job for whatever reason, if you have a 401(k) account, you will have several options - take a lump sum payout (with possible tax penalties), keep the funds where they are if your company allows this, or do an IRA Rollover - transfering the funds to an existing or new IRA account.
