Personal taxes with a single member LLC through TurboTax $240, that also includes two states since I work and live in different states. We don't have a very complicated tax situation, even with the LLC.
The last two years have been the only years that I used a CPA, mainly because I was scared of the LLC but have since learned it's not that complicated. Those years cost $500 each. On top of that, they missed a Maryland LLC filing for both years. I was able to do that earlier this year when I got the notice in the mail, fortunately there wasn't a penalty.
Where I work is a S Corp, those taxes were $3100 including 1099s, 1120 and some misc meetings and tax prep discussions.
