They probably thought you would save some $$$$ on Self employment taxes (currently at 15.3%) Take a small salary (subject to se tax) and the rest in a distribution which is not subject to SE Taxes. It depends on your situation but it can save you some cash to set it up this way. Plus with an s corp it is easier to transfer to a c corp election if you so choose to do so.

Ya i plan i taking a VERY small salary and then paying myself the rest in dividends, and my wife is also an "employee" b/c we needed 2 employees for health insurance. But i still need to figure out how to work out the tax vs dividends thing. my current accountant is a retard so i'm looking for a new one right now...
