Agree with TGB, unless there already are employees (but you listed Solo 401(k)). Also, this affects office in home deduction, vehicle mileage allowance, meals and lodging provisions; there are some ">2% shareholder" limitations and ">10% shareholder" limitations. They already get a benefit from health care premiums (so that's a wash). If that income isn't a nice, regular, feed, then S Corp management really is difficult by comparison to SP.
