IRS Tax Tip 2019-18, March 5, 2019 When someone legally changes their name, there are tax consequences they need to know about, especially at tax time. People change their names for several reasons: Taking their spouse’s last name after a marriage Hyphenating their last name with their spouse’s after getting married Going back to their former name after a divorce Giving an adopted child the last name of their new family The IRS wants people experiencing a name change to remember these important things: Reporting change to SSA. Taxpayers should notify the Social Security Administration of a name change ASAP. When a taxpayer files their taxes, the IRS checks SSA records to ensure names and social security numbers on the forms match. Failing to report a name change. If a name on a taxpayer’s tax return doesn’t match SSA records, it can delay the IRS processing of that return. In that case, if the taxpayer is due a refund, it will take longer for them to get their money. Name Change Due to Adoption. In the case of an adoption, if the child has a Social Security number, the taxpayer should be sure to inform the SSA of a name change. If the child does not have a Social Security number, the taxpayer may use an Adoption Taxpayer Identification Number on their tax return. An ATIN is a temporary number. Taxpayers can apply for an ATIN by filing Form W-7A, Application for Taxpayer Identification Number for Pending U.S. Adoptions. Taxpayers file this form with the IRS. Getting a New SS Card. After a name change, a taxpayer should file Form SS-5 PDF, Application for a Social Security Card. The form is available on SSA.gov or by calling 800-772-1213. The taxpayer’s new Social Security card will reflect the name change. Subscribe to IRS Tax Tips
