Form 540
Form 540 is the longest form used to file California income tax returns. There are no requirements that you need to meet to file Form 540. Thus this is the form to use if you didn't meet the requirements for Form 540 2EZ or Form 540A. Form 540 allows you to claim the most adjustments, deductions, and credits. Claiming more adjustments, deductions, and credits reduces your tax liability by increasing your refund.
To see if you need file a California return see Do I Have To File. There are two other California tax return forms, 540A and 540 2EZ. However both of these forms have requirements you must meet to use them. To see if you meet these requirements see the Chart.
