My head hurts!

What 3 letter word is EVIL and makes heads hurt?? TAX...okay I guess you put it as a 5 letter word...TAXES! Either way, they are a pain in the butt! Ours are pretty simple, basic filling, no extras really, but I seem to have to prepare them on atleast 3 different sites to see what they all come up with, and then I have to fill out a paper form as well. And do you think I get the same amount on them all?? Normally not on all 4. There comes the headaches! I go with the one that gives us the most amount back and least amount to pay, makes sense right! Add in the kids keep trying to talk to me and it's a mess. So now I'm going to wait until they are in bed and try to figure it out without ripping too much hair out, lol.
