Right - so you may want to change to S-Corp for future years, but that comes with some overhead too, so consider carefully.
Now you got me thinking. In the past, income has been just enough over the SS max that I'd only save on medicare for this type of move, or at least the vast majority would be only medicare. Combine with my middle-man telling me something to the effect of "if you incorporate, then we're doing corp-to-corp, which is a different kind of deal", and I decided "eh, not worth the hassle". But I'm working less now, so there's more tax to be saved . . . maybe worth the hassle.
