Does a California tax return need a copy of the Federal return?

If you are filing Form 5402EZ or Form 540A, do not attach a copy of your federal return to your California return. If you are filing Form 540 you must attach a copy of your federal return to your California return only if you filed any schedules other than schedule A or schedule B with your federal return. If you are filing form 540NR, you must always attach a complete copy of your federal return to your California return.
