R0000-503-01 SSN or Name Mismatch
Unfortunately, your e-file was rejected by the IRS because your spouse's Social Security number and last name does not match the IRS's records. The IRS receives this information from the Social Security Administration.
What you can do to fix this rejection
First, verify your spouse's information is correct
To correct this error, log back into your tax software and verify your spouse's personal info is correct. You can make any required corrections and retransmit your return.
If the information you entered is correct, call the Social Security Administration (SSA) at 1-800-772-1213 to verify your spouse's Social Security number, date of birth, and name. If the information from the SSA differs from what you entered, log back in to make the corrections and retransmit as described above.
If the information you entered is the same as what the SSA has on record, you'll need to print and mail your return as any e-file attempts will continue to be rejected by the IRS.
If you have not filed your taxes yet and are shopping for tax software, we recommend TaxAct.
