Attachments to your tax return.

Do I need to attach a copy of federal Form 1040 or 1040-SR?

Other than Schedule A (Form 1040) or Schedule B (Form 1040), did you attach any federal forms or schedules to your federal Form 1040 or 1040-SR?

If No , do not attach a copy of your federal Form 1040 or 1040-SR return to Form 540.

If Yes , attach a copy of your federal Form 1040 or 1040-SR return and all supporting federal forms and schedules to Form 540.

Exception : If you did not itemize deductions on your federal tax return but will itemize deductions on your California tax return, complete and attach a copy of the federal Schedule A (Form 1040) to Form 540.

Do not attach any documents to your tax return unless specifically instructed. This will help us reduce government processing and storage costs.
