How to Choose the Right Form
Navigating California Franchise Tax Board (FTB) requirements depends primarily on your residency status and your business structure. Use the following breakdown to identify which California tax forms you need to complete.
Individual Resident Filers
Most people living in California year-round will use one of two primary forms to report personal income:
- Form 540 2EZ, California Resident Tax Return: This is the streamlined version for individuals with basic tax situations. Choose this if you have no dependents, use the standard deduction, and meet specific income thresholds.
- Form 540, California Resident Income Tax Return: This is the standard form for full-year residents. Use this if you have more complex finances, such as itemized deductions, adjustments to income, or specific tax credits that the 2EZ version does not support.
Non-Residents and Part-Year Residents
If you earned income from California sources but lived in another state for all or part of the year, you must use:
- Form 540NR, California Nonresident Tax Return: This form is designed to calculate tax only on the portion of your income sourced within California while accounting for your total worldwide income to determine the correct tax rate.
Business and LLC Compliance
If you operate a business entity registered in the state or doing business within state lines, you have specific entity-level filing requirements:
- California Form 568, Limited Liability Company Return of Income: This is the essential filing for LLCs. It is used to pay the annual $800 LLC tax, calculate the LLC fee based on gross income, and report member allocations.
Claiming the Earned Income Tax Credit
To reduce your tax liability and potentially increase your refund, you may need to attach supplemental schedules:
- Form FTB 3514, California Earned Income Tax Credit: If you are a low-to-moderate-income worker, use this form to claim the CalEITC. This must be filed in conjunction with your Form 540 or 540NR to verify your eligibility for the credit.
Form Comparison
| Form | Who Files It | Purpose | Key Requirement |
|---|---|---|---|
| Form 540, California Resident Income Tax Return | Full-year California residents with standard or complex income sources. | Reports total annual income and calculates state income tax liability. | Required for residents who do not qualify for the 2EZ form. |

| Form 540 2EZ, California Resident Tax Return | Residents with basic tax situations, limited income types, and no dependents. | Provides a simplified, faster method for filing individual state income tax. | Only available for taxpayers meeting strict income and filing status limits. |
| California Form 568 (2023), Limited Liability Company Return of Income | LLCs registered or doing business in California, including disregarded entities. | Reports business income and calculates annual LLC taxes and fees. | Used to pay the $800 annual tax and income-based fee. |
Tips for California tax forms
California offers three main versions of the personal income tax return depending on your status. Ensure you choose Form 540NR if you lived in the state for only part of the year, or the 540 2EZ if your tax situation is straightforward, to avoid processing delays or incorrect tax calculations.
When filing Form 568, remember that most LLCs must pay an $800 annual tax plus a fee based on total California income. Failing to include these payments or the required Schedule IW can result in late fees and penalties from the Franchise Tax Board.
Using AI-powered tools like Instafill.ai can complete these complex California tax forms in under 30 seconds with high accuracy. Your data remains secure during the entire process, providing a practical and time-saving solution for users managing multiple state filings.
California tax law often differs from federal law regarding depreciation, health savings accounts, and certain deductions. Carefully review your income adjustments on Form 540 or 568 to ensure you are reporting based on state-specific rules rather than simply duplicating federal figures.
If you are filing Form 540 or 540NR, always check if you qualify for the CalEITC using Form FTB 3514. This refundable credit can significantly reduce your tax liability or increase your refund, even if you do not owe any state taxes for the year.
Form 568 often requires additional schedules like Schedule K or Schedule B to report member allocations and ownership changes. Ensure all supplementary pages are completed and that the totals match the primary return to prevent the FTB from flagging your filing for errors.
A common cause for rejected California tax forms is a simple typo in a Social Security Number or Secretary of State file number. Always verify these identifiers on every page of your return, especially when filing for a business entity to ensure payments are credited to the correct account.
