* Due to IRS and state tax agency tax data sharing and validation requirements, you can only e-file a state income tax return while also e-filing a federal income tax return. This is not an efile.com created policy, but all online tax web sites have to adhere to this IRS/state issued tax data sharing policy. Find out how to only prepare and file a state tax return. Only on efile.com can you prepare and efile unlimited state tax returns for one low price. Most other sites charge a per state price.

California efile Error Codes

If your California state return was rejected by the state and not efile.com, you will receive an error reject code. If you prepared and efiled your return on efile.com, we will provide you with an explanation of how to correct the error on your return. You may then resubmit your state return at no additional charge until it is accepted by the state. View a list of all California State efile Income Tax Return Error Reject Codes.

How To File a California Tax Extension

If you are certain that you cannot file your California return by the deadline, you do not need to file for an extension. You will automatically receive a 6-month extension of time to file your return (not to pay). The extended tax return due date is October 15, 2019. Please be aware that California will not accept the federal extension form as an extension for your California tax return. If you owe taxes and you submit your extension electronically, file Form FTB-3582 with your payment. 

Important: Do you need to prepare and e-file an IRS or federal tax extension as well?

How to File A California Tax Amendment

Amended California tax returns can only be mailed; they cannot be efiled. Learn how to file a California tax amendment.

Important Reminder! If you are filing a California tax amendment, you may need to file a federal tax amendment as well.

Odd California Tax Fact

A "jock tax" is a special income tax levied on traveling athletes, entertainers, and other nonresident performers who worked in the state at some point during the year. There are now "jock taxes" in more than 40 states, but the very first state to levy such a tax was California. The tax was originally levied in 1991, just in time to tax Michael Jordan's income after the Chicago Bulls beat the LA Lakers in the NBA finals.
