Does changing my name affect my taxes?

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
If you don't report a name change - If a name on a your tax return doesn’t match SSA records, it can delay the IRS processing of that return. In that case, if the you are due a refund, it will take longer for them to get your money.
Reporting change to SSA - You should notify the Social Security Administration of a name change ASAP. When a you file your taxes, the IRS checks SSA records to ensure names and social security numbers on the forms match.
Get a new Social Security card - After a name change, you should file Form SS-5, Application for a Social Security Card. The form is available on SSA.gov or by calling 800-772-1213. Your new Social Security card will reflect the name change.
Name change due to adoption - In the case of an adoption, if the child has a Social Security Number, the you should be sure to inform the SSA of a name change. If the child does not have a Social Security Number, the you may use an Adoption Taxpayer Identification Number on your tax return. An ATIN is a temporary number.
