If you are a "spouse beneficiary" for both the Keogh and the IRA, then you may transfer or roll over the inherited IRA assets to your own Traditional IRA, and you can also roll over the assets from the Keogh to the same IRA.
If you are a "non-spouse beneficiary" of the IRA, you must maintain the IRA assets in the inherited IRA. (For more on your distribution options, see Inherited Retirement Plan Assets.) And, if you are a non-spouse beneficiary of the Keogh (a type of qualified plan) distributions that you receive cannot be rolled over.
If the employer that adopted the Keogh was a sole proprietor, it may mean that the assets must be distributed from the Keogh as soon as possible, because there is no business to continue the maintenance of the Keogh plan. However, before you decide how to distribute the assets, be sure to talk to a competent tax professional about your options. Be sure to discuss ways to defer paying taxes on the amount, even if you are forced to distribute the balance from the Keogh. You may also want to discuss the matter with the financial institution that currently holds the assets.
