You are correct, reject code F1040-526-03 because the date of birth entered by the spouse doesn't match date of birth information that the IRS has obtained from the Social Security Administration.
If you have made sure that all information has been entered correctly, call the Social Security Administration (SSA) at (800) 772-1213 to verify that their records are correct. If SSA records are updated, it can take up to four weeks to transfer the updated information to the IRS. Wait four weeks and then re-file the return.
If the reject continues, or if you don't want to wait four weeks to re-file electronically, you may print and file this return by mail.
