A name change can affect your taxes. As all the names on a tax return must match Social Security Administration (SSA) records, a name mismatch can delay your tax refund.

Report Name Changes: Got married and now using a new spouse’s last name or hyphenate a name? Divorced and now back to using a former last name? In either case, you should notify the SSA of a name change. That way the new name on IRS records will match the SSA records.

Make Dependent’s Name Change: Notify the SSA if a dependent had a name change. For example, if you adopted a child and the child’s last name changed. If the child does not have a Social Security number, you may use an Adoption Taxpayer Identification Number on your tax return. An ATIN is a temporary number. Apply for an ATIN by filing Form W-7A with the IRS.

Get a New SS Card: File Form SS-5, Application for a Social Security Card. The form is on SSA.gov or by calling 800-772-1213.
