I found I could have been filing my adult son the past few years as a dependent because he had no income and been out of a job and he lives with me. I always get more in state taxes than I owe in federal but with adding a dependent with no income I can get much more. We live in NY. My questions are
1) If I amend the taxes to add him as a dependent how many years back can I do so?
2) Will I also receive the refunds I'm owed or is there any limit to that?
3) Can my son also file the past few years his back taxes and receive the little that new york state taxes provide back for most even if you don't work? Such as school credits etc.
