Congratulations on your marriage!
You can file a joint tax return with your spouse as long as you were married by December 31st of the tax year for which you’re filing a return.
For example, If you were married last year, you can file a joint return with your spouse and use the filing status married filing jointly for this year’s tax return. However, if you marry in the current year, then you won’t be eligible to file a joint return for last tax year.
Review your Basic Info to select your filing status if you haven’t submitted your return to the IRS yet. If you’ve already submitted your tax return with a single filing status, and the IRS accepted it, you’ll need to file an amended return to change your filing status to reflect your marriage.
