I own a small, privately-held corporation and am looking for ways to invest my corporation's money more effectively.

The problem is the government taxes passive investment income inside a corporation at a staggering rate of almost 50%. I do not want to invest this money personally either, as I want asset protection. So far the only direction that looks promising is some sort of a trust fund (~25% tax?) I haven't had better advice from a financial advisor.

Does anyone have better suggestions?
