If you are married when the tax year closes, you can file jointly. For most taxpayers, that means if you are married at 11:59:59 p.m. on December 31, you can file jointly, even if you've been married for less than a second.
no you can file seperately.
If your common law marriage is recognized in the state where you now live, or in the state where the relationship began, you are considered married for tax purposes. Assuming that you are living with your spouse, you may file as Married Filing Jointly or Married Filing Separately. You may not file as Single or Head of Household.
You can't file Married Filing Jointly if you aren't a married couple. While you're engaged, you each have to file as Single. But no matter when you marry during the year, you can file Married Filed Jointly for the year in which you marry.

If you are married
You can file as "married filing jointly". However , I don't know how being married may yet effect EIC.
You can file your federal taxes jointly if you are married. Even if your spouse is unemployed, filing jointly means he or she is still responsible for any outstanding taxes due should you not pay.
