Problem: The IRS - not eFile.com - rejected your tax return because your name and SSN doesn't match IRS records.
Solution: Sign into your eFile.com account at https://mytaxes.efile.com/1040/SignIn/. Click Name and Address on the left side of your account screen and review your name and SSN. If the information is entered incorrectly, correct it and save your changes. Then re-eFile your federal and state returns at no additional charge. However, if it's entered correctly, print your return(s) from your account, sign it, and mail it to the IRS and/or state tax agency.

Contact Social Security and see if the issue with the SSN and/or name is with them as they share data with the IRS: Social Security Administration. You may also need to call IRS taxpayer assistance at 1-800-829-1040.
