Hello personal finance,
I was filing my taxes for 2016 and I just found out that I transitioned from Non-Resident-Alien to Resident Alien around September last year by passing substantial presence test. After doing some research, I have found out that I qualify as a resident alien for the whole tax year (from January 2016).
Unfortunately, my employer did not know about this change in status, so for all of 2016 no Social Security or Medicare taxes were withheld.
I have found out that I need to correct this, and I need help figuring out a few things.
- Should I have a W-2 re-issued? I spoke to two accountants and one said I should, the other said I shouldn't. I don't know which one to believe.
- Who pays for the FICA I should have paid last year? Is it my employer's problem to fix or mine?
- Should I file the taxes with the old or the new W-2?
- As best as I understand it, the new W-2 will be written as if I made this contributions. So there will be a discrepancy between what I actually earned and what the W-2 says. How should I handle this discrepancy? Declare it as extra income? Or claim it back in case I earned less than I should have?
