You really need to talk to a good accountant that understands the nature of your business, your goals and the tax implications. I don't know about US law, but in Canada there are distinct disadvantages to keeping large amounts of cash inside a operating small business corporation and you would potentially be better off distributing the cash or setting up a separate holding company for it (or rather having your lawyer & accountant handle that). You can then invest within the holding company but keep your operating business and investments separate.
