The IRS rejected your return because your business name/EIN didn't match what the one IRS already has on file. You'll want to verify that the EIN in your account is correct and that your business name is listed the same as how you registered it with the IRS. We recommend contacting the IRS EIN Hotline at 1-800-829-4933 to confirm your information.
Note: If you have a new EIN, it takes approximately 10 business days or 2 weeks for the number to become active within the IRS e-filing system. If you obtained your EIN less than two weeks ago, this is likely the reason for the rejection.
