If My Name Changed Recently, Do I Need a New Social Security Card?
Yes. If your name ever changes because of marriage, divorce, or some kind of legal action, you've got to get a new social security card and show it to your employer (payroll office). First, fill out SS-5 to file your name change with the SSA. When you get your new card in the mail, take it in to your employer and have your name changed on the payroll records. If your employer changes your name before your receive your new card, someone may make a mistake in reporting wages to your social security account. The possible result: you might receive less money than you should when you retire or become disabled. Destroy your old card.
There's another good reason for getting a new social security card when you change your name. If you're married and file a joint tax return with your spouse, the IRS will reject the joint return if the names and social security number on the return don't match the SSA's records.
