Beware: The IRS is cracking down on small-business owners who participate in tax-reduction insurance plans sold by insurance agents, including defined benefit retirement plans, IRAs, and even 401(k) plans with life insurance. In these cases, the business owner is motivated by a large tax deduction; the insurance agent is motivated by a substantial commission.
A few years ago, I testified as an expert witness in a case in which a physician was in an abusive 401(k) plan with life insurance. It had a so-called "springing cash value policy" in it. The IRS calls plans with these types of policies "listed transactions." The judge called the insurance agent "a crook."
