California also sets its own deduction. It does not borrow the federal figure. The deduction lowers taxable income; it is not a dollar-for-dollar credit. This guide covers the amounts, eligibility, the senior and blind rules, the federal comparison, the standard-versus-itemized decision, and a filing checklist. Figures are in US dollars.
Key Takeaways
- Tax year 2026 California standard deduction: $5,900 (single/MFS) and $11,800 (joint, head of household, surviving spouse).
- Federal and California amounts differ; you can choose different methods on each return.
- Seniors and blind filers get $153 exemption credits (tax year 2025), not a larger California deduction.
- Compare eligible California itemized deductions against the standard amount, and keep records.
California Standard Deduction 2026: Amounts and Eligibility
What the deduction means
The standard deduction is a fixed amount subtracted from California adjusted gross income (AGI) to reach taxable income. Exemption credits work differently. They come off the tax itself, after the rate schedule is applied.
Filing-status amounts
The Franchise Tax Board (FTB) published tax year 2026 amounts in its October 2026 Tax News, using a 3.4% indexing measure.
| Filing status | Tax year 2025 (filed 2026) | Tax year 2026 (filed 2027) |
|---|---|---|
| Single | $5,706 | $5,900 |
| Married/RDP filing separately | $5,706 | $5,900 |
| Married/RDP filing jointly | $11,412 | $11,800 |
| Head of household | $11,412 | $11,800 |
| Qualifying surviving spouse/RDP | $11,412 | $11,800 |
Why the tax-year label matters
- Tax year 2025: due April 15, 2026, with an automatic filing extension to October 15, 2026. The extension does not extend time to pay.
- Tax year 2026: filed in 2027. Confirm the annual-return due date on the FTB site before you plan.
- Use only final tax year 2026 forms once the FTB releases them. The FTB warns against filing on draft forms or relying on draft instructions.
Who may claim it
- Full-year residents use Form 540, or the simplified Form 540 2EZ if eligible. The 2EZ does not allow itemizing, married filing separately, or blind filers.
- Part-year residents and nonresidents use Form 540NR. The deduction is allocated by California AGI divided by total AGI, not by months of residence.
- Dependents get a limited deduction. For tax year 2025 it is the smaller of the regular amount or the greater of $1,350 or earned income plus $450.
- Separated spouses or RDPs must both itemize or both take the standard deduction.
A simple example
Say a single filer has $80,000 of California AGI for tax year 2026. Subtract $5,900 and taxable income is $74,100. Exemption credits, the rate schedule, withholding, and estimated payments come after that. The deduction only shrinks the income the brackets apply to.
California vs. Federal Rules and Age-Based Provisions
Comparing the two deductions
The IRS announced federal 2026 amounts that sit far above California's.
| Filing status | Federal TY2026 | California TY2026 |
|---|---|---|
| Single / MFS | $16,100 | $5,900 |
| Married filing jointly / surviving spouse | $32,200 | $11,800 |
| Head of household | $24,150 | $11,800 |
Different methods on each return
California treats the choice independently. Pick whichever is larger on each return, subject to the spouse rule above:
- Federal standard deduction with California itemizing
- Federal itemizing with the California standard deduction
California-only itemizers enter federal Schedule A figures on Schedule CA.
Senior and blind rules
California does not add an age or blindness amount to the standard deduction. It offers exemption credits instead.
| Credit (tax year 2025) | Amount |
|---|---|
| Personal: single, MFS, HOH | $153 |
| Personal: joint, surviving spouse | $306 |
| Senior (65+), each person | $153 |
| Blind, each person | $153 |
| Dependent | $475 |
The October 2026 announcement lists tax year 2026 personal credits of $158 (single/MFS/HOH) and $316 (joint/surviving spouse), plus $491 per dependent. Confirm blind and senior credit amounts on the final FTB forms, since that announcement did not list them separately.
These credits are nonrefundable: they can reduce your tax to zero, not below. High-income filers also face a phase-out. For tax year 2025 it begins above federal AGI of $252,203 (single/MFS), $378,310 (HOH), or $504,411 (joint).
A credit cuts tax directly. A deduction cuts taxable income. They are not interchangeable.
Federal rules differ. Federal additional standard deductions for age or blindness are $2,050 (single/HOH) and $1,650 (married statuses) for 2026. A separate federal senior deduction of up to $6,000 per person age 65+ is income-phased and available to itemizers.
Standard Deduction vs. Itemized Deduction: Which Is Better?
The basic choice
On a single return you take the standard deduction or itemize, not both. Across your federal and California returns, the choices can differ.
California itemized categories (tax year 2025 rules)
- Medical and dental: the threshold is 7.5% of federal AGI.
- State and local taxes: Disallows state income tax, SDI, and general sales tax. No federal SALT cap ($40,000 for 2025, or $20,000 MFS; phases down above $500,000 MAGI).
- Mortgage interest: Acquisition-debt limit is $1 million ($500,000 MFS) versus federal $750,000. Home-equity interest still allowed within California limits.
- Charitable gifts: California uses a 50%-of-federal-AGI limit, reconciled on Schedule CA.
- Casualty and disaster losses: Personal casualty, theft, and disaster losses allowed beyond federal rules. Use California amounts on Form 4684.
- High-income limit: above the thresholds, itemized deductions drop by the smaller of 6% of excess AGI or 80% of affected deductions.
Don't carry federal limits onto the California return automatically. Schedule CA reconciles the differences.
A practical break-even test
- Gather eligible California expenses.
- Apply the limits that California, not the IRS, uses.
- Total the itemized amount.
- Compare it with the California standard deduction.
- Take the larger allowable figure.
Renter: Modest charitable gifts and some medical costs rarely near $5,900, so the standard deduction usually wins.
Homeowner: Large mortgage interest, property tax, or medical costs after the 7.5% floor can beat the standard amount. Run the numbers.
Records to keep
- Mortgage interest statements (Form 1098)
- Property-tax bills and payment proof
- Medical receipts and insurance statements
- Charitable acknowledgments
- Disaster-loss documentation
Keep business and rental expenses on their own schedules. Don't deduct them as personal itemized items.
How California State Income Tax Is Calculated After the Deduction
The sequence
- Start with income, then apply California adjustments to reach AGI.
- Subtract the standard or itemized deduction to get taxable income.
- Apply the rate schedule or tax table.
- Subtract exemption and other credits.
- Subtract withholding and estimated payments.
- The result is your balance due or refund.
Progressive brackets
California uses marginal rates, so only income inside each band is taxed at that band's rate. For tax year 2025, single filers face these bands:
- 1% on the first $11,079
- 2%, 4%, 6%, 8%, and 9.3% up to $371,479
- 10.3%, 11.3%, and 12.3% above $742,953
Joint filers' bands are roughly double.
Form 540 filers with taxable income of $100,000 or less use the tax table. Above that, they use the rate schedules. Final tax year 2026 schedules are expected in late December, so don't use 2025 schedules for 2026 planning.
An additional 1% Behavioral Health Services Tax applies to taxable income above $1 million.
Standard versus itemized, illustrated
Take two hypothetical single filers, each with $90,000 of AGI. One takes the $5,900 standard deduction. The other has itemizable expenses larger than that and deducts the higher total.
The second filer exposes less income to the brackets. The difference lands in the higher marginal bands, which is where the savings come from. Run your own figures through the FTB schedules for an actual number.
Other factors
- Filing status and residency status (full-year, part-year, nonresident)
- California-source income for nonresidents (out-of-state services generally excluded; deferred and equity pay can be exceptions)
- Exemption credits, withholding, and estimated payments
The deduction alone never determines what you owe.
2026 Filing Checklist and When to Get Tax Help
Pre-filing checklist
- Confirm the tax year and your filing period
- Confirm filing and residency status
- Download current FTB and IRS forms, not drafts
- Collect W-2s, 1099s, and other income documents
- Gather deduction records
- Check exemption credit eligibility, including senior and blind credits
- Complete the standard-versus-itemized comparison for each return
Mistakes to avoid
- Using a tax year 2025 amount for tax year 2026
- Assuming California uses the federal deduction
- Claiming both methods on one return
- Overlooking senior or blind credits
- Trusting software without reviewing state-specific adjustments
When professional help makes sense
A professional review is worth considering when your return includes:
- Income in multiple states
- Self-employment or rental income
- Stock compensation or foreign income
- Business interests
- Large itemized deductions
VJM Global's CPAs handle federal, state, and local obligations across all 50 U.S. states. The firm also prepares Form 1040 and 1040-NR returns and assists non-resident aliens with US-sourced income. California filings that involve any of these situations can use that multi-state and 1040/1040-NR support. VJM Global's US presence is a New York branch, not a California office.
Tax rules change. Confirm current amounts and eligibility with the FTB, the IRS, or a qualified tax professional before you file.
