Hi Guys,
I got married in 2013 but at that time my wife was not here in US and I didn't have her ITIN so I filed as single. Now, since she got her SSN, I want to file tax ammendment as married.
What should be the reason I mention for this in the 1040x (exact wording please)? Also,should I file as married filing joint or married filing separate? and should i include any supporting documents (like marriage certificate) as well?
Thanks.
