California does not conform to the federal OBBBA overtime deduction. While the federal deduction saves single workers up to ~$2,750 on their federal return, California still taxes 100% of overtime income at state rates up to 13.3%. A CA worker earning $15,000 in overtime premium (deduction capped at $12,500) misses out on roughly $1,163 in state savings ($12,500 × 9.3%) compared with a California that conformed. FICA still applies everywhere.

Key Facts
California State Conformity Status
NOT conformed. California has not adopted the OBBBA overtime deduction, so there is no California deduction for overtime pay. Source: California Franchise Tax Board (FTB).
California State Tax Rate on Overtime
1% to 13.3% — same as all other CA wage income. No state exemption or deduction applies to overtime premium pay. At $90,000 total income (single), the applicable marginal bracket is typically 9.3%.
Federal OBBBA Deduction — Still Applies to CA Workers
California workers DO receive the federal overtime deduction on their IRS Form 1040. Up to $12,500 (single) or $25,000 (MFJ) of qualifying FLSA overtime premium is deductible from federal taxable income. The federal saving is real — the state saving does not exist.
California Daily Overtime (Labor Code §510)
California requires overtime after 8 hours in a single workday — not just 40 hours/week (federal FLSA threshold). Double time applies after 12 hours in a day. Overtime also applies on the 7th consecutive day worked in a workweek. These CA-specific daily overtime hours do NOT qualify for the federal OBBBA deduction.
FICA on Overtime — No Change
Social Security (6.2%) and Medicare (1.45%) apply to all overtime pay regardless of the OBBBA or California's non-conformity. FICA is a federal payroll tax; it is unaffected by either federal or state income tax policy changes.
Phase-Out Thresholds (Federal Deduction)
The federal OBBBA overtime deduction is reduced by $100 for each $1,000 of modified AGI above $150,000 (single) or $300,000 (MFJ). California's own high earner surcharge (1% on income over $1,000,000) continues to apply with no modification.
CA Starts From AGI
The OBBBA overtime deduction is claimed on federal Schedule 1-A and reduces taxable income, not AGI. California starts from federal AGI and applies its own California deductions, and it has none for overtime, so the overtime pay stays fully taxable for California purposes.
Sunset
The federal OBBBA overtime deduction expires December 31, 2028. California's non-conformity question will be moot if the federal provision is not extended. Monitor FTB guidance annually.
Introduction
No Tax on Overtime in California 2026: The Federal Deduction Applies, the State Benefit Does Not
The One Big Beautiful Bill Act (OBBBA, P.L. 119-21) created a federal income tax deduction of up to $12,500 (single) or $25,000 (married filing jointly) on qualifying overtime premium pay for tax years 2025–2028. For most US workers, this is a meaningful saving. For California workers, the picture is more complicated — and less generous at the state level.
California has explicitly not conformed to the OBBBA overtime deduction. That means California workers do receive the federal income tax saving on their IRS return, but the federal deduction — claimed on Schedule 1-A below AGI — does not carry over to their California return, and California has no deduction of its own. The state taxes 100% of overtime pay at California's full income tax rates — which reach up to 13.3% for high earners. At the same time, California operates its own daily overtime rules under Labor Code §510 that give hourly workers more overtime protection than the federal FLSA — but those California-specific daily overtime hours do not qualify for the federal OBBBA deduction at all.
This guide explains exactly what California workers do and do not save, how California starts from federal AGI, California's unique daily overtime rules, FICA obligations, and what high-overtime workers in California — nurses, firefighters, construction workers — should plan for in 2026.
Section 01
California's Non-Conformity: Why CA Still Taxes Your Overtime
California has a long history of selectively decoupling from federal tax law changes. When Congress passes new deductions or credits, California does not automatically adopt them — the California legislature must pass separate conforming legislation. As of June 2026, no such legislation has passed for the OBBBA overtime deduction.
How California Tax Conformity Works
California operates on a selective conformity model. Unlike states with rolling conformity (which automatically adopt federal changes), California picks and chooses which federal provisions to adopt. In many cases, California explicitly rejects provisions that reduce tax revenue. The OBBBA overtime deduction represents a meaningful revenue cost for any state that adopts it — and California, with ongoing budget pressures, has not moved to conform.
How California Starts From Federal AGI
If you claim the federal OBBBA overtime deduction on Schedule 1-A of your IRS Form 1040 (reducing your federal taxable income by, say, $12,500), it does not change your federal AGI, which is where California starts. California has not adopted the deduction, so nothing on the California return reduces your overtime pay: your California income tax is calculated as if the overtime pay were ordinary wages.
FTB Guidance
The California Franchise Tax Board (FTB) is the authoritative source for how to report non-conforming federal deductions on California returns. Workers who claim the OBBBA overtime deduction on their federal return should review FTB guidance for the applicable tax year. Always verify current FTB instructions at ftb.ca.gov before filing.
Why This Is Unique to California
California's non-conformity means the federal saving stops at the federal return. Workers who use tax software (TurboTax, H&R Block, FreeTaxUSA) should verify that the California module treats the federal overtime deduction correctly — not all software handles new OBBBA provisions correctly in the first filing year. If in doubt, verify the California return manually before submitting.
What You Do Save: The Federal Overtime Deduction Still Applies
California's non-conformity does not eliminate the federal benefit. California workers still receive the full federal OBBBA overtime deduction on their IRS return — the only gap is the state level.
Federal Deduction Mechanics
The OBBBA created a deduction (claimed on Schedule 1-A) for qualifying FLSA overtime premium pay. It reduces your federal taxable income (not AGI), and you do not need to itemize to benefit from it. Key limits:
Single filers: up to $12,500 in qualifying overtime premium deductible from federal income
Married filing jointly: up to $25,000
Phase-out: $100 per $1,000 of modified AGI above $150,000 (single) / $300,000 (MFJ); a full deduction is gone at $275,000 / $550,000
Applies to: FLSA overtime premium only — the extra 0.5× rate for hours over 40/week for FLSA non-exempt employees
Duration: Tax years 2025–2028; expires December 31, 2028
Worked Example: CA Worker, $75,000 Base + $15,000 Overtime Premium
Single California worker. $75,000 base salary. $15,000 in qualifying FLSA overtime premium pay. Total gross income: $90,000.
Federal OBBBA deduction: $12,500 (single filer cap — $15,000 earned, but capped at $12,500)
Federal taxable income after deduction: $90,000 minus standard deduction ($16,100 est.) minus $12,500 overtime deduction = approximately $61,400 federal taxable income
Federal income tax saving from the deduction: $12,500 × 22% marginal rate ≈ $2,750 saved federally
California taxable income: $90,000 minus CA standard deduction — there is no California overtime deduction, so the full $90,000 income is subject to state tax
California income tax on $90,000 (single, approximately 9.3% marginal bracket): approximately $4,200–$4,300 in CA state income tax (before credits)
Hypothetical CA savings if CA had conformed: $12,500 × 9.3% = approximately $1,163 in state tax that is NOT saved
The Bottom Line on Federal vs. State
A California single worker earning $15,000 in overtime premium in 2026 saves approximately $2,750 in federal income tax — a real and meaningful benefit. They do not receive any California state income tax reduction. Compared with a California that allowed the same $12,500 deduction, this worker pays roughly $1,163 more in state tax on the same overtime income. The federal deduction is worth claiming — it just does not fully eliminate the California state burden.
California Daily Overtime: Different Rules Than Federal
California's overtime rules are significantly more protective of workers than federal FLSA rules — and this creates an important wrinkle for the OBBBA federal deduction.
California Labor Code §510: The Daily Overtime Rule
Daily overtime: Any hours worked beyond 8 hours in a single workday must be paid at 1.5× the regular rate — regardless of the total weekly hours.
Double time: Any hours worked beyond 12 hours in a single workday must be paid at 2× the regular rate.
7th consecutive day: All hours worked on the 7th consecutive day of work in a workweek must be paid at 1.5×. Any hours beyond 8 on that 7th consecutive day must be paid at 2×.
Weekly overtime: Hours over 40 in a workweek also trigger overtime (same as federal FLSA), but the daily overtime rule is the key California distinction.
This is enforced by the California Division of Labor Standards Enforcement (DLSE) and the California Department of Industrial Relations (DIR).
The Critical OBBBA Distinction: Daily OT Does Not Qualify for the Federal Deduction
The OBBBA federal overtime deduction applies only to overtime premium pay that qualifies under the FLSA — that is, the extra 0.5× rate for hours over 40 in a workweek for FLSA non-exempt employees. California-required daily overtime (hours 8–12 in a single day) that occurs within a 40-hour workweek does not qualify for the federal OBBBA deduction — because it is not FLSA overtime. It is California-mandated overtime only.
Example: A California worker works four 10-hour days (40 hours total in the week). Under California law (absent an adopted alternative workweek schedule), they earn 8 hours of daily overtime premium (the 2 extra hours on each of four days). Under federal FLSA, they worked exactly 40 hours — no FLSA overtime at all. Result: 8 hours of overtime premium pay that is fully taxable at both the federal and California level, with no OBBBA deduction available on any of it.
What This Means for California Workers in Practice
California workers often earn two types of overtime premium: (1) FLSA-qualifying weekly overtime (hours over 40/week) — this qualifies for the federal deduction; and (2) California-only daily overtime (hours 8–12/day, double time over 12/day, 7th day) — this does NOT qualify for the federal deduction. Payroll records should ideally distinguish between these categories, though many employers aggregate overtime pay on paychecks without the FLSA/CA split. If you need to calculate your qualifying federal deduction amount, you or your employer need to identify what portion of your overtime premium was FLSA weekly overtime vs. California daily overtime.
Neither the OBBBA federal overtime deduction nor California's non-conformity changes anything about FICA (Federal Insurance Contributions Act) taxes. FICA applies to every dollar of overtime pay — full stop.
What FICA Covers
Social Security tax: 6.2% (employee share) on wages up to the annual wage base ($184,500 in 2026; indexed annually)
Medicare tax: 1.45% (employee share) on all wages, no cap
Additional Medicare Tax: 0.9% on wages exceeding $200,000 (single) or $250,000 (MFJ) — applies to total wages, not just overtime
Your employer matches 6.2% Social Security and 1.45% Medicare on your behalf. Total FICA on overtime wages: 15.3% (combined), of which you pay 7.65% and your employer pays 7.65%.
Why FICA Cannot Be Deducted Away
The OBBBA is a federal income tax law change. FICA is a payroll tax — an entirely separate system established under a different statute. Congress would need to pass separate payroll tax legislation to modify FICA obligations on overtime pay. No such legislation exists. The deduction reduces your income tax base; it has no interaction with FICA withholding.
Practical Impact for California Workers
On $15,000 of overtime premium pay:
FICA (employee share): $15,000 × 7.65% = $1,147.50 owed
Federal income tax: reduced by $2,750 via OBBBA deduction (as shown in Section 2)
California state income tax: approximately $1,395 on the $15,000 (at 9.3% marginal rate) — no deduction applies
Total taxes on $15,000 overtime premium for a California single worker (22% federal bracket, 9.3% CA bracket): approximately $3,093 ($550 federal on the $2,500 above the $12,500 deduction cap + $1,148 FICA + $1,395 California) — compared to approximately $5,843 without the OBBBA federal deduction. The federal deduction saves real money; FICA and California state tax remain fully applicable.
CA Workers in High-OT Jobs: What to Expect and How to Plan
California has a large workforce in industries where substantial overtime is routine — healthcare, public safety, construction, and logistics. Workers in these fields face the fullest impact of California's non-conformity.
High-Overtime Industries in California
Registered Nurses and Healthcare Workers: California nurses are among the highest-paid hourly workers in the US and regularly work overtime due to staffing requirements. A nurse earning $60/hour who works 10 hours of FLSA overtime per week earns $30/hour premium × 10 hours × 52 weeks = $15,600 in annual overtime premium. Federal deduction: $12,500 (capped). Federal saving: ~$2,750. California saving: $0. The $15,600 is fully taxable at California rates — at $120,000 total income, the marginal CA rate is 9.3%, producing approximately $1,451 in California tax on the overtime premium ($15,600 × 9.3%), of which about $1,163 ($12,500 × 9.3%) is the amount a nurse in a California that allowed the federal deduction would not pay.
Police Officers and Firefighters: Public safety workers in California earn significant overtime through shift coverage requirements and emergency response. For workers whose annual overtime premium exceeds $12,500, the federal deduction is capped at $12,500 (single) — only a portion of their total overtime premium is federally deductible. California taxes the full amount. At higher total incomes, California marginal rates may be 10.3% or higher, producing significant state tax on overtime that would be reduced or eliminated in conforming states.
Construction and Trades Workers: California construction projects involving prevailing wage requirements often generate substantial overtime. Electricians, ironworkers, and plumbers on large commercial projects regularly earn 20–30 hours of weekly overtime during peak project phases. The combination of FLSA weekly overtime and California daily overtime means these workers need to carefully track which overtime hours qualify for the federal deduction.
Logistics and Warehouse Workers: California's massive warehouse and distribution sector employs hundreds of thousands of hourly workers. Overtime is frequent during peak seasons. These workers are typically in lower California income tax brackets (1%–4%), so the conformity gap is smaller — but it still exists.
Planning Strategies: Reduce Both Federal and California Tax
Since California does not provide relief on overtime income, the most effective tax planning strategies are those that reduce total taxable income at both the federal and state level simultaneously:
Maximize 401(k) or 403(b) contributions: Pre-tax retirement contributions reduce both your federal AGI and your California taxable income. A California worker maximizing 401(k) contributions ($24,500 in 2026; $32,500 if age 50+) reduces California income tax on all wages — including overtime — at their marginal state rate. At 9.3%, a full $24,500 contribution saves approximately $2,279 in California state income tax alone.
Health Savings Account (HSA): If enrolled in a qualifying high-deductible health plan, HSA contributions ($4,400 single / $8,750 family in 2026) are deductible federally. Note: California does NOT recognize HSA deductions — contributions are not deductible for CA purposes.
Traditional IRA contributions: Deductible IRA contributions (if eligible based on income and workplace plan participation) reduce federal AGI. California follows the federal IRA deduction rules, so this saves at both levels.
Supplemental wage withholding check: California employers withhold supplemental wages (including overtime) at a flat 6.6% CA rate for withholding purposes — but your actual California marginal rate may be higher. Check your total withholding at year-end to avoid an underpayment penalty.
The federal overtime deduction provides significant savings for California workers on the federal side. Comprehensive tax planning that maximises retirement contributions is the most effective way to reduce the California state tax burden on high overtime income.

No. California does not conform to the federal OBBBA overtime deduction. California taxes all overtime pay at full state income tax rates — from 1% up to 13.3% depending on total income. There is no California state exemption, deduction, or credit that reduces the tax on overtime pay. California workers do receive the federal OBBBA income tax deduction on their IRS return (up to $12,500 single / $25,000 MFJ), but California has no matching deduction, so it does not reduce their California state income tax.
Q
How much is overtime taxed in California in 2026?
Overtime in California is taxed as ordinary income at California's progressive state income tax rates: 1%, 2%, 4%, 6%, 8%, 9.3%, 10.3%, 11.3%, 12.3%, and 13.3% (the top rate, which includes the 1% mental health surcharge on income above $1,000,000). For most full-time workers earning overtime, the relevant bracket is typically 9.3% (the exact income range for each bracket depends on the year's FTB tax rate schedule — verify with the FTB). FICA taxes (Social Security 6.2% + Medicare 1.45%) also apply to all overtime, on top of the state and federal income taxes.
Q
Does the federal overtime deduction apply to California workers?
Yes — at the federal level only. California workers receive the full OBBBA federal income tax deduction (up to $12,500 single / $25,000 MFJ) on their IRS Form 1040. This saves federal income tax. However, California does not conform to this deduction for state tax purposes, and California has no deduction of its own for overtime. So the deduction applies federally but not to California state income tax.
Q
What is California's daily overtime rule?
Under California Labor Code §510, overtime is required after 8 hours worked in a single workday (not just 40 hours per week as under federal FLSA). Double time (2× regular rate) applies after 12 hours in a day. On the 7th consecutive day worked in a workweek, all hours are paid at 1.5×, and hours beyond 8 on that day are paid at 2×. Importantly, this California-specific daily overtime does NOT qualify for the federal OBBBA overtime deduction — only FLSA overtime (hours over 40 per week) qualifies for the federal deduction. California workers who earn daily overtime within a 40-hour week receive no federal tax benefit on that overtime.
Q
How much would I save if California conformed to the overtime deduction?
It depends on your total income and the amount of qualifying overtime. For a single California worker earning $15,000 in FLSA overtime premium in the 9.3% CA bracket: if California conformed to the federal cap, they would save approximately $12,500 × 9.3% = $1,163 in state income tax (the deduction is capped at $12,500 for a single filer). For a higher-income worker in the 10.3% bracket with $25,000 in overtime premium (filing jointly): the potential saving would be $25,000 × 10.3% = $2,575. These are the amounts California workers currently pay in state tax on overtime income that they would save if California passed conforming legislation.
Q
Do California workers still have to pay FICA on overtime?
Yes. FICA taxes — Social Security (6.2%) and Medicare (1.45%) — apply to all overtime pay for all workers, regardless of state or the OBBBA. FICA is a federal payroll tax that is separate from income tax. The OBBBA only changed the federal income tax code. California's non-conformity is about state income tax. Neither change affects FICA. On $10,000 of overtime premium, FICA costs $765 (employee share) — this amount is fixed regardless of whether you live in California, Texas, or any other state.
