Problem: The IRS - not eFile.com - has rejected your return, as the Social Security Number of the Spouse has been used on another return accepted by the IRS.
Solution: Please sign in to your eFile.com account now and click on My Return in the upper left and review the IRS message on the right.
1. Sign in: https://mytaxes.efile.com/1040/SignIn/
2. Click on Name & Address and verify the SSN of the Spouse on your return. If the SSN is indeed correct, please ask your spouse if a return was filed under this SSN. If not you can mail them in if you wish. Here is the IRS mailing address: https://www.efile.com/irs-mailing-addresses/
For state addresses please visit: https://www.efile.com/state-income-tax-returns/
You should however contact the IRS or the Social Security Admin. (ssa.gov) about this issue if no return was filed under the SSN.
If you have questions, please contact us as soon as possible so we can assist you with your Tax Return.
