Problem: The State of California—not eFile.com—rejected your California Income Tax Return because the Social Security Number (SSN) of the primary or spouse has been used on an accepted CA tax return.
Solution: Sign into your eFile.com account at https://mytaxes.efile.com/1040/SignIn/, and check all your SSN entries. If you don't see an error, do not submit or re-efile your CA return. Please PRINT your CA return from your account, sign it, and MAIL it to the State of CA. Visit the CA state page for more detail.
