I was misclassified as an independent contractor in 2011 and I therefore received a 1099-MISC and filed as such. I should have been considered an employee and been issued a W-2 instead.
I therefore want to file form 1040x. I already tried once, but it got rejected since I wasn't able to provide a W-2. I was told to file form SS8 as well.
My question is: will that be sufficient? Or are there any other forms I should file? For example, I know there exists Form 4852 (Substitute for Form W-2, Wage and Tax Statement).
In case it matters, I'm not sure if my former employer ever corrected this misclassification with the federal government. I believe they corrected it at least with the state of MA. I can show that I filed as a W-2 (with the same company) in 2010, and can provide my W-2 from 2012 as evidence as well. I will also include an email exchange I had with my former boss where he acknowledges the mistake and tells me to refile my 2011 taxes.
