Is there any software that has ALL the forms? I doubt it. As I'm sure many of us have done the 8919 (taxpayer claiming they are not an independent contractor when they have a 1099) I finally got to see the "other side", when an employer now has to reclassify workers as employees due to the 8919.
Form 8952, plus correcting 1099's and issuing W2's, plus having to do quarterlies, (both federal and state) and year end 940 (federal unemployment). Luckily we do have payroll software, (Quick books), but it would only print current year quarterlies. Had to go to IRS.gov and they do have printable forms for past years, but of course there is no way to save them, meaning I had to print 3 copies. One to mail, one for client, and one for us. Client needed to go back 2 years. After seeing the work involved to reclassify workers as employees, I wonder how often this happens because an employer doesn't understand the difference between employee & independent contractor. Getting "caught" is not only time consuming but expensive!
