Q) Do I need to change my maiden name on my Social Security card to file jointly? A) According to the IRS: No. You can still file “Married Filing Jointly” without changing your name with the Social Security Administration.
A) No, you do not need to change your maiden name on your Social Security card to file jointly. You can file jointly with your spouse even if you have different last names. When you file your tax return, you will need to provide your Social Security number and the Social Security number of your spouse. You will also need to provide your spouse’s name, even if it is different from yours.
If you have recently changed your name, you may need to provide documentation of your name change to the IRS. This documentation could include a copy of your marriage certificate, divorce decree, or court order for a name change.
You can find more information about filing jointly on the IRS website.
