The last couple years I&#x27;ve filled out my tax forms with a couple different online forms and found they gave different results. (Last year I filed my state taxes through one company and federal through another) The fact that programs that exist only to do taxes can&#x27;t even agree on how much my taxes are shows how broken the USA&#x27;s tax system is. (and my returns are fairly simply. I can&#x27;t imagine how different they would be if I had complicated returns)
