Most likely, the IRS has the wrong date of birth on file. In this scenario, you won't be able to e-file because the date you're entering doesn't match their records.
Keep following the onscreen instructions and we'll help you file your return by mail.
Tip: To prevent this rejection next year, call the Social Security Administration (SSA) at 1-800-772-1213 to verify their records (this is where the IRS database pulls from). If the info is wrong, please allow 4–6 weeks for correction.
