Overview of California State Income Tax for 2022

Who Needs to File

California residents, part-year residents, and nonresidents with California-source income must file a state income tax return if their gross income meets certain thresholds established by the Franchise Tax Board. Residents include anyone who lived in California for the entire year, while part-year residents lived here for only part of 2022, and nonresidents earned California income but lived elsewhere. These distinctions matter because filing status determines which forms you use—Form 540 for residents and Form 540NR for nonresidents and part-year filers—and the applicable income thresholds.

2022 Gross Income Filing Thresholds

California’s 2022 gross income filing thresholds vary by filing status, age, and number of dependents. If your income equals or exceeds the amounts below, you must file a return:

  • Single person or Head of Household under age 65: Must file if gross income is at least $20,913 with no dependents, $35,346 with one dependent, or $46,171 with two or more dependents.

  • Single or Head of Household age 65 or older: Must file if gross income is at least $27,913 with no dependents, $38,738 with one dependent, or $47,398 with two or more dependents.

  • Married/RDP filing jointly where spouses are under 65: Must file if gross income is at least $41,830 with no dependents, $56,263 with one dependent, or $67,088 with two or more dependents.

  • Married/RDP filing jointly where one spouse is 65 or older: Must file if gross income is at least $48,830 with no dependents, $59,655 with one dependent, or $68,315 with two or more dependents.

  • Married/RDP filing jointly where both spouses are 65 or older: Must file if gross income is at least $55,830 with no dependents, $66,655 with one dependent, or $75,315 with two or more dependents.

Refer to the official California Franchise Tax Board website for complete details on state income tax return requirements.

Key Dates and Deadlines

Observing California’s filing and payment deadlines is critical to avoid penalties and interest on unpaid taxes.

  • April 18, 2023: Original due date to file your 2022 return and pay any taxes owed. This deadline applies even if you request an extension and coincides with most taxpayers' federal income tax return deadline.

  • October 16, 2023: Automatic six-month extension to file your 2022 return without a late-filing penalty. You do not need to submit Form FTB 3519 for this state extension, but you must pay at least 90% of your expected tax liability by April 18 to avoid underpayment penalties.

What’s New for 2022 vs. 2021

The 2022 tax year introduced several changes and expanded benefits designed to provide relief and simplify filing:

  • Young Child Tax Credit Expansion: The Young Child Tax Credit now applies to individuals with zero or negative earned income, making more families eligible for this state-level income tax credit.

  • Foster Youth Tax Credit Introduction: For the first time, qualifying former foster youth ages 18–25 can claim a refundable credit up to $1,083, offering targeted support for this often at-risk population.

  • Repeal of Net Operating Loss Suspension and Credit Limitations: California reinstated the ability to use net operating losses from prior years and removed prior caps on most refundable credits, aligning state rules more closely with federal tax returns.

  • New Income Exclusions: Specific rebates and discharges—such as turf replacement rebates, student fee relief discharges, and Middle Class Tax Refund payments—are now excluded from gross income, reducing your state tax burden if you received any of these benefits.

These updates reflect adjustments to align California tax law with federal provisions and targeted relief measures enacted by the state legislature.

What Forms to Use for Your 2022 Return

Main Individual Income Tax Forms

  • Form 540 – California Resident Income Tax Return: This is the primary state income tax form used by full-year California residents. You must complete Form 540 if you lived in California all of 2022 and your gross income meets the filing thresholds.

  • Form 540 2EZ – Simplified California Tax Return: Use this streamlined version if you have a straightforward tax situation with taxable income of $100,000 or less. It reduces the number of lines and schedules you must complete, helping you file more quickly.

  • Form 540NR – Nonresident or Part-Year Resident Return: This form applies if you were a part-year resident or nonresident with California-sourced income in 2022. It allows you to report only the income earned in California and calculate the correct state tax liability.

Essential Schedules and Supporting Forms

  • Schedule CA (540) – California Adjustments: You use Schedule CA (540) to reconcile federal and California taxable income differences. This schedule is required if you have any California-specific income or adjustments, such as state tax refunds or differences in depreciation rules.

  • Form FTB 3514 – Earned Income and Related Credits: Claim the California Earned Income Tax Credit, Young Child Tax Credit, and Foster Youth Tax Credit on Form FTB 3514. This form combines multiple refundable credits to ensure you receive all credits for which you qualify.

  • Form FTB 3532 – Head of Household Filing Status Schedule: Complete Form FTB 3532 if you are filing as head of household to verify eligibility. It documents qualifying dependents and ensures you meet the criteria for the head-of-household filing status.

  • Form FTB 3568 – Alternative Dependent Identification: Use Form FTB 3568 when a dependent does not have a Social Security Number or ITIN. This alternative identifying information form allows you to claim the dependent exemption credit without standard identification numbers.

All official California tax forms and instructions are available for free download online. Many forms are also available in Spanish for your convenience.

Step-by-Step Instructions to Complete Your Return

Step 1: Gather Your Documents

Assemble all income and payment records—including W-2s, 1099s, your prior year’s California and federal returns, confirmations of estimated payments, receipts for deductions, and documentation for any credits—to accurately report income and substantiate your credit claims.

Step 2: Determine Your Filing Status

Use the same filing status as on your federal return, but apply California-specific rules: registered domestic partners must file as married/RDP, active-duty military stationed in California may file separately from a nonresident spouse, and nonresident spouses can elect to report only their California income by filing separately.

Step 3: Complete Your Forms

Transfer your federal adjusted gross income from your IRS-filed Form 1040 to Form 540 (or 540NR for part-year/nonresidents), add any California-specific income or exclusions, and reconcile differences on Schedule CA (540). Then use the FTB tax tables or the online calculator to compute your state tax liability.

Step 4: Claim Credits and Review

File Form FTB 3514 to claim refundable credits—California Earned Income Tax Credit, Young Child Tax Credit, and Foster Youth Tax Credit—and recover any excess State Disability Insurance withheld. Finally, double-check that withholding amounts match Box 17 of your W-2, verify estimated payments, confirm dependents’ IDs, and proof all math to avoid delays.

These condensed steps cover the essentials—gathering your paperwork, selecting the correct status, completing your forms, claiming credits, and avoiding common mistakes—so you can file accurately and efficiently.

Common Mistakes to Avoid

  • Using federal withholding instead of California withholding: Many taxpayers include the federal income tax withheld on their state return. Always use the amount in Box 17 of your W-2 for California withholding to ensure payments are credited correctly and avoid underpayment penalties.

  • Misstating estimated payments: If you made quarterly estimated tax payments, double-check the dates and amounts against your bank records or Form 540-ES vouchers. Inaccurate entries can trigger penalties or processing delays.

  • Claiming ineligible dependents: Do not list a dependent already claimed on another return or without a valid Social Security number or ITIN. Incorrect dependency claims often lead to extended processing times and requests for additional documentation.

  • Applying the wrong standard deduction: California’s standard deduction amounts differ from federal figures and vary by filing status. Using the federal deduction on your state return can misstate your taxable income and result in unexpected balances due.

  • Simple arithmetic and data-entry errors: Transposing numbers, entering Social Security numbers incorrectly, or making math mistakes are common causes of return rejections. Carefully proofread every line, and use the FTB’s online calculator or software checks when available.

How to File Your California Tax Return

Electronic Filing Options

California taxpayers can file their 2022 return online for free using CalFile, the Franchise Tax Board’s e-filing system. CalFile provides immediate confirmation, automatic calculations, and the fastest refunds—direct-deposit returns typically arrive within 7–10 business days. You only need internet access and a valid email address to use CalFile. If you prefer working with tax software or a preparer, the FTB maintains a list of approved e-file providers on ftb.ca.gov.

Paper Filing Instructions

If you choose to mail a paper return, send Form 540 (or 540 2EZ/540NR and any schedules) to the appropriate FTB P.O. Box, based on your balance status:

  • If you owe money, mail it to the Franchise Tax Board, PO Box 942857, Sacramento, CA 94257-0531.

  • If you expect a refund or have a zero balance, mail it to Franchise Tax Board, PO Box 942840, Sacramento, CA 94240-0001.

Use certified mail for proof of mailing, keep copies of everything you send, and allow 6–8 weeks for processing a paper return.

Filing Extensions

California automatically grants a six-month extension to file your 2022 return until October 16, 2023—no extension form is required. However, any tax due must still be paid by April 18, 2023, to avoid underpayment penalties and interest. To minimize extra charges, estimate and pay at least 90% of your tax liability by the original deadline.

How to Make a Payment

Web Pay (Direct Bank Transfer)

California’s Web Pay system allows you to transfer funds directly from your checking or savings account at no cost. You can schedule same-day or future payments and receive an immediate confirmation number for your records. To use Web Pay, visit ftb.ca.gov/pay/bank-account, enter your Social Security number, bank routing, and account numbers, select your payment date (must be by April 18, 2023), and save the confirmation for proof of payment.

Paid Payment Options

  • Credit or Debit Card Payments: You can pay online or by phone using Visa, MasterCard, American Express, or Discover, but a convenience fee of approximately 2.3% applies. Online payments are processed immediately via ftb.ca.gov/pay/credit-card.html, and you can also call 800-272-9829 to pay by phone.

  • Check or Money Order: Make your check or money order payable to “Franchise Tax Board” and include your Social Security number and tax year on the memo line. Mail to the same addresses used for paper filing (see the filing section above), keep a copy for your records, and allow extra time for delivery to meet the April 18 deadline.

Payment Deadlines & Penalties

All taxes owed for the 2022 tax year must be paid by April 18, 2023, even if you file later under an extension. Late payments incur a penalty of 5% of the unpaid tax plus 0.5% interest per month (up to 25% total), and underpayment penalties may apply if you did not pay at least 90% of your liability through withholding or estimated payments. To avoid these charges, make sure your payment is posted by the deadline and check the 2023 estimated tax payment schedule—due on April 18, June 15, September 15, and January 16—if you anticipate owing taxes next year.

How to Track Your Refund or Balance Due

“Where’s My Refund?” Tool

Use the FTB’s “Where’s My Refund?” portal for real-time status updates. You’ll need your Social Security number, exact refund amount, and ZIP code. If you prefer phone access, call 800-852-5711 and follow the automated prompts.

MyFTB Account Access

Create or log in to your secure MyFTB account at ftb.ca.gov/myftb to view your refund status, account balance, payment history, and any notices. The mobile-friendly interface also lets you update personal information and track multiple tax years in one place.

Processing Times & Troubleshooting

CalFile typically processes electronic returns in 7–10 business days for direct-deposit refunds, while paper e-filed returns take 2–3 weeks, and fully paper returns require 6–8 weeks. Complex returns or those claiming new credits may take up to 16 weeks. If you see no status after these timeframes, verify your information, allow for peak-season delays, and contact FTB customer service if necessary.

Final Filing Checklist

  • Review all documents and forms: Ensure you have completed and signed Form 540 (or 540 2EZ/540 NR) along with Schedule CA (540), Form FTB 3514, Form FTB 3532, and any other required schedules. Verifying each form is accurate and included prevents processing delays and missing credits.

  • Verify payment and refund details: Confirm that your payment method—Web Pay, credit/debit card, or check—is scheduled or mailed to arrive by April 18, 2023, and that bank account information is correct for direct-deposit refunds. Keeping your confirmation numbers and payment records organized will help quickly resolve discrepancies.

  • Confirm your filing method and extension status: If you e-filed, ensure you received an immediate confirmation number via CalFile or your software provider. If you mailed your return, use certified mail or a trackable service and note the postmark date; if you filed under extension, verify it’s for the October 16, 2022, deadline.

  • Maintain thorough records: Save copies of your complete tax return, W-2s, 1099s, IRS payment confirmations, and credit documentation for at least four years. Setting up and securing your MyFTB account ensures you can access your filing history, payment history, and notices anytime.

Frequently Asked Questions

What if I missed the filing deadline for April 18, 2023?

You can still file your 2022 California tax return by October 16, 2023, without facing the failure-to-file penalty. However, any tax owed was due on April 18, and late-payment penalties of 5% per month plus interest will apply. California offered a one-time penalty abatement for eligible taxpayers on qualifying grounds.

Can I e-file my state tax return for free? 

Yes, the Franchise Tax Board’s CalFile system lets all California taxpayers file their state income tax return at no cost. CalFile provides immediate filing confirmation, automatic calculations, and the fastest refunds—direct-deposit returns typically arrive within 7–10 business days. You only need internet access and a valid email address to use this free e-file service.

Which deductions are most commonly missed on California returns?

Taxpayers often overlook California-specific deductions, such as moving expenses claimed via Form FTB 3913 and excess State Disability Insurance refunds. Municipal bond interest and certain state tax refunds may differ from federal treatment, so reconciling on Schedule CA is essential. Self-employed business expenses and nonprofit charitable contributions also frequently go unclaimed.

How do I request a filing extension for California?

California automatically grants a six-month extension to file your state tax return, moving the deadline to October 16, 2023, without requiring Form FTB 3519. To avoid underpayment penalties, you must pay at least 90% of your estimated tax liability by April 18, 2023. Interest applies to any remaining balance from the original due date.

Can I file jointly if I moved mid-year?

If you and your spouse moved together, you generally file as full-year residents on Form 540. Part-year residents or nonresidents use Form 540NR to report only California-source income. Active-duty military stationed here may file separately from a nonresident spouse under the military exception. Always follow the residency guidelines set by the Franchise Tax Board.

What’s new with tax credits in California for 2022? 

For 2022, the Young Child Tax Credit expanded to include individuals with zero or negative earned income, and the new Foster Youth Tax Credit offers up to $1,083 for former foster youth ages 18–25. California also repealed the net operating loss suspension and state credit limits to align more closely with federal tax return rules.

How long should I keep my California tax records?

The Franchise Tax Board recommends retaining tax records for at least four years from the original filing deadline. Keep records for six years if you underreported income by 25% or more. There is no time limit if you failed to file or if fraud is suspected. Business records should be kept for four years after the return is filed.
