If you get married are you suppose to use your last name from year before

[VolvoGirl]

Use whatever name is on file at Social Security.  If you changed it late try using your old name.

The IRS verifies you by the information that is on file with the Social Security Office.  If you have not changed your name with the SSA, then use your maiden name.  If your new name gets rejected, then use your maiden name.
