What California Form 540 (2015) Is For
The California Form 540 is the primary income tax return for full-year residents of California. You use it to report your income, calculate your tax liability, and claim credits that reduce what you owe. The form covers wages, interest, dividends, self-employment income, retirement benefits, and other taxable sources of revenue. California taxes all income earned by its residents, regardless of whether it originates from within or outside the state. Form 540 helps determine whether you should pay more tax or expect a refund.
When You’d Use California Form 540 (2015)
You use California Form 540 when you were a full-year resident and need to file a 2015 income tax return with the California Franchise Tax Board. Filing is required when your income or Adjusted Gross Income meets the state thresholds for your filing status. Some residents, even those with a lower income, must file, such as those seeking a refund of California tax withholding or those who owe specific state taxes that affect their overall tax liability.
Form 540 is also used when filing late returns or correcting past filings. If you need to make a tax amendment for 2015, you must use Form 540X. Part-year and nonresidents should use Form 540NR instead of Form 540. Visit the IRS Form Help Center for guidance on federal forms needed to complete your 2015 California Form 540 accurately.

Step-by-Step Filing Instructions (High Level)
To complete California Form 540 for the 2015 tax year, you follow a sequence that helps you report income, calculate your tax liability, and prepare an accurate income tax return. These steps offer a clear starting point:
- Complete your federal return first: Your federal Form 1040 provides the necessary figures for income, deductions, and credits, which you will use to make California adjustments.
- Gather your documents: Collect W-2s, 1099s, receipts, prior California returns, estimated tax payments, and records related to use tax or personal items purchased from an out-of-state retailer.
- Report your income and make adjustments: Enter your federal income and use Schedule CA to reflect differences between federal and California tax rules, including adjustments to your Adjusted Gross Income.
- Choose your deduction method: Use the standard deduction or itemized deductions, depending on which provides the better result for your California tax.
- Apply credits and confirm withholding: Review credits you qualify for and verify all California tax withholding reported on your forms.
- Assemble, sign, and file your return: Sign the form, attach required schedules, and mail it to the correct California Franchise Tax Board address or e-file when available.
Common Mistakes and How to Avoid Them
Common issues can affect the accuracy of your 2015 income tax return and may change your final tax liability. These problems often involve incorrect entries or missing schedules. You can prevent most errors by carefully reviewing your documents:
- Many taxpayers enter incorrect withholding totals from W-2s or 1099s. By adding each form separately and comparing the totals to personal records, you can avoid this error.
- Some filers forget to include Schedule CA when federal and California tax rules differ, and this issue can be prevented by checking whether any income or deduction requires a state adjustment.
- Dependent information is sometimes missing or incorrect, and this issue is avoided by confirming each dependent’s name and SSN before completing the return.
- Estimated tax payments are often overstated or entered incorrectly, and this mistake can be reduced by verifying all payments through the California Franchise Tax Board account.
- Some filers use Form 540NR instead of Form 540, and this can be prevented by confirming residency status before selecting a form.
A final review of all entries and required attachments helps reduce filing mistakes.
What Happens After You File
After you submit your 2015 California income tax return, the California Franchise Tax Board reviews the information for accuracy and completeness. E-filed returns are typically processed more quickly than paper returns, and refunds are issued once the review is complete. Some taxpayers may receive notices if the FTB requires clarification or identifies discrepancies in reported income, deductions, or estimated tax payments.
The FTB also has a standard audit window for verifying details from the return. Taxpayers who cannot pay the full amount may request an installment agreement. See how payment plans can help when taxpayers cannot pay their whole California or federal balance owed after completing the 2015 Form 540.
