Marriage, Divorce, Taxes and Your Social Security Number
Newlyweds and the recently divorced should make sure that names on their tax returns match those registered with the Social Security Administration (SSA). A mismatch between a name on the tax return and a Social Security number (SSN) could unexpectedly increase a tax bill or reduce the size of any refund.
For newlyweds, the tax scenario can begin when the bride says "I do" and takes her husband's surname, but doesn't tell the SSA about the name change. If the couple files a joint tax return with her new name, the IRS computers will not be able to match the new name with the SSN.
Similarly, after a divorce, a woman who had taken her husband's name and had made that change known to the SSA should contact the SSA if she reassumes a previous name.
It's easy to inform the SSA of a name change by filing Form SS-5 at a local SSA office. It usually takes two weeks to have the change verified. The form is available on the agency's Web site, http://www.ssa.gov/, by calling toll free 1-800-772-1213 and at local offices. The SSA Web site provides the addresses of local offices.
Generally, taxpayers must provide SSNs for each dependent claimed on the tax return. For adopted children without SSNs, the parents can apply for an adoption taxpayer identification number, or ATIN, by filing Form W-7A with the IRS. The ATIN is used in place of the SSN on the tax return. You can download the form or order it by calling the Internal Revenue Service (IRS) toll free at 1-800-TAX-FORM (1-800-829-3676).
