When we used to go to our tax preparer, she charged us $100 for both mine and my hubby's. That was on the low end. I think she normally charged $100/per and $150/business + personal.

Now we go to a chartered accountant b/c of my hubby's business so I have no idea what it costs as he does our personal taxes along with our businesses.

We, too, always get a lump sum back.
