How Much Do You Need to Make to File Taxes in California?

For the 2025 tax year, a single Californian under 65 with no dependents has to file a state return once their California gross income reaches $22,941 or their California adjusted gross income reaches $18,353. Those numbers move up with age, marriage, and dependents. So the honest answer to how much you need to make to file taxes in California is: it depends on your household, and even a low earner can be required to file if they owe tax, want a refund, or went without health insurance.

The Franchise Tax Board (FTB) checks two income figures against the charts for your filing status and age. If either one hits its threshold, you have to file. California gross income is everything you received during the year in money, goods, property, or services that is not exempt from tax. California adjusted gross income starts from that figure and subtracts adjustments like IRA contributions or self-employment deductions.¹

2025 Income Thresholds With No Dependents

California groups Single and Head of Household filers together at the same base thresholds. Married/RDP Filing Jointly and Married/RDP Filing Separately share one set of thresholds, because spouses filing separately have to combine their income when checking whether either of them needs to file.¹

California gross income triggers a filing requirement at:

Single or Head of Household, under 65: $22,941
Single or Head of Household, 65 or older: $30,591
Married/RDP Filing Jointly or Separately, both under 65: $45,887
Married/RDP Filing Jointly or Separately, one spouse 65 or older: $53,537
Married/RDP Filing Jointly or Separately, both 65 or older: $61,187

California adjusted gross income triggers a filing requirement at:

Single or Head of Household, under 65: $18,353
Single or Head of Household, 65 or older: $26,003
Married/RDP Filing Jointly or Separately, both under 65: $36,711
Married/RDP Filing Jointly or Separately, one spouse 65 or older: $44,361
Married/RDP Filing Jointly or Separately, both 65 or older: $52,011

The higher figures for people 65 or older reflect California’s Senior Exemption Credit. A single filer under 65 has to file once adjusted gross income reaches $18,353; at 65 or older, that same person gets an extra $7,650 of room before the requirement kicks in.¹

One birthday quirk: if you turn 65 on January 1, 2026, California treats you as 65 on December 31, 2025.

How Dependents Change the Numbers

Every dependent you claim raises the income level at which you have to file. For 2025 California gross income, the thresholds work out as follows.¹

Single or Head of Household:

1 dependent, under 65: $38,774
1 dependent, 65 or older: $42,466
2 or more dependents, under 65: $50,649
2 or more dependents, 65 or older: $51,966

Married/RDP Filing Jointly or Separately:

1 dependent, both under 65: $61,720
1 dependent, one 65 or older: $65,412
2 or more dependents, both under 65: $73,595
2 or more dependents, both 65 or older: $82,562

Adjusted gross income thresholds follow the same pattern. A head of household filer under 65 with one dependent, for instance, does not have to file until adjusted gross income reaches $34,186. Because head of household status requires a qualifying dependent, the 1-dependent column is effectively the starting line for that status.¹

Qualifying Surviving Spouse/RDP filers always have at least one dependent, and their thresholds match the Single or Head of Household figures at each dependent level.²

If Someone Else Can Claim You as a Dependent

The thresholds above do not apply if you can be claimed as a dependent on another taxpayer’s return. In that case you have to file a California return whenever your gross income exceeds your allowable standard deduction for the year.¹

For 2025, the dependent standard deduction is the larger of $1,350 or your earned income plus $450, capped at $5,706 (the single filer standard deduction). In practical terms:

Only unearned income (interest, dividends, capital gains distributions): file if it exceeds $1,350.
Only earned income (wages, tips, self-employment): file if it exceeds $5,706.
Both types: file if total gross income exceeds your calculated standard deduction.

Nonresidents and Part-Year Residents

If you earned California-sourced income as a nonresident, or you lived in California for only part of 2025, you use the same threshold charts as full-year residents. The test looks at your total worldwide gross income and your California adjusted gross income, not just the portion tied to California. Nonresidents and part-year residents file Form 540NR rather than the standard Form 540.²

California-sourced income includes wages for work done in the state, rent from California real property, gains from selling California real estate, and income from a California-based business or profession.²

When You Have to File Even Below the Threshold

Income is only one trigger. Several other situations force a return regardless of what you earned.

You Owe California Tax

Any California income tax owed creates a filing requirement, including the Alternative Minimum Tax. AMT can apply when certain deductions or income exclusions push your regular tax below the state’s minimum. Schedule P (540) determines whether it hits you.³

You Want a Refund or a Refundable Credit

If your employer withheld California tax and you earned below the filing threshold, filing is the only way to get that money back. The California Earned Income Tax Credit (CalEITC) and the Young Child Tax Credit (YCTC) are refundable, meaning they can pay you even if you owe no tax, but you have to file Form FTB 3514 with your state return to claim either one.⁴ A Foster Youth Tax Credit is also claimed on the same form.⁵

You Owe Use Tax

If you bought items from out of state and were not charged California sales tax, you likely owe use tax. Most purchases under $1,000 can be reported on Form 540 using the FTB’s lookup table, or paid directly to the California Department of Tax and Fee Administration. Vehicles, vessels, aircraft, and mobile homes have to go through the CDTFA separately and cannot be reported on your income tax return.⁶

You Went Without Health Coverage

Since January 1, 2020, California residents have to maintain qualifying health insurance or pay a penalty on their state return. For 2025, the monthly penalty is based on the statewide average bronze plan premium of $377 per person, capped at five household members ($1,885 per month). The penalty and any exemptions are reported on Form 3853.⁷

Exemptions that can reduce or eliminate the penalty include:

Household income below the applicable filing threshold.
The cheapest available plan costing more than 7.28% of household income.
A coverage gap of three consecutive months or fewer.
Months as a bona fide resident of another state.
Incarceration, health care sharing ministry membership, membership in a federally recognized Indian tribe, and certain hardship situations.

Some hardship and religious exemptions have to be obtained through Covered California before you file.⁸

Deadline and What Happens if You Skip It

The deadline to file your 2025 California return and pay any tax owed is April 15, 2026. California automatically extends the filing deadline to October 15, 2026, with no application needed, but the extension covers only the return. Any tax owed is still due April 15, and interest starts running the next day.⁹

Miss the deadline with tax owed and the FTB charges 5% of the unpaid tax for the first month late, plus 5% for each additional month, up to 25%. File more than 60 days late and the minimum penalty is $135 or the tax due, whichever is less. Fraudulent failure to file carries 15% per month, up to 75%. Interest accrues on any unpaid balance; for July 1, 2025 through June 30, 2026, the FTB charges 7% on personal income tax underpayments.¹⁰

If the FTB sends a notice demanding that you file and you still do not, a separate 25% penalty can be added on top of the late-filing penalty.¹¹
