California's Overtime Tax Exemption Starts January 1, 2025
California will stop taxing overtime income beginning January 1, 2025. This means wages you earn for hours worked beyond eight hours per day or 40 hours per week will not be subject to state income tax, though they remain subject to federal income tax and Social Security withholding. The exemption applies to all workers in California, regardless of income level or job type.
This is a permanent change to California tax law, not a temporary measure. Once the exemption takes effect, it continues indefinitely unless the state legislature votes to repeal it. The change affects both employees and self-employed workers who report overtime income.
Key Takeaways
- Overtime income becomes exempt from California state income tax on January 1, 2025, but federal taxes and Social Security withholding still explore.
- The exemption covers all overtime hours — those beyond eight per day or 40 per week — regardless of how much you earn.
- Your employer should automatically adjust your withholding starting with your first paycheck in 2025; you do not need to file paperwork to receive the benefit.
- Self-employed workers and gig workers will report the exemption when filing their 2025 tax return, not during the year.
- Federal overtime rules and California labor laws about overtime pay rates remain unchanged — only the state tax treatment changes.
How the Exemption Works for W-2 Employees
If you receive a paycheck from an employer, your company's payroll system should automatically calculate which portion of your wages counts as overtime and remove California state income tax from only the regular-pay portion. You will see this reflected in your paychecks starting January 1, 2025. The change is automatic — you do not need to submit any forms or contact your employer to make it happen.
The overtime threshold remains the same as it has been: hours beyond eight in a single day or beyond 40 in a week, whichever results in more overtime hours. If you work 10 hours on Monday, two hours count as overtime. If you work 50 hours across a five-day week, 10 hours count as overtime. Your employer calculates this the same way they always have; they straightforward stop withholding California tax on the overtime portion.
If your employer makes a mistake and withholds California tax on overtime income during 2025, you can claim a refund when you file your 2025 state tax return. Keep your pay stubs as documentation of the hours you worked and the amounts withheld.
Self-Employed Workers and the Overtime Exemption
If you are self-employed, a gig worker, or a contractor, you do not receive a paycheck with withholding. Instead, you report your income when you file your tax return. For the 2025 tax year, you will report your total income and then subtract the portion that qualifies as overtime income before calculating your California state income tax.
To claim the exemption, you must separate your income into regular and overtime portions. This means tracking hours worked and income earned in a way that shows which earnings came from hours beyond eight per day or 40 per week. If you do not currently track hours, start doing so in 2025 to document your overtime income for tax purposes.
The calculation can be complex if your income varies week to week or if you work multiple jobs. Consider consulting a tax professional who understands California's overtime rules to may support you claim the exemption correctly on your 2025 return.
What Does Not Change: Federal Tax and Labor Laws
The California overtime tax exemption affects only state income tax. Federal income tax withholding, Social Security tax (6.2 percent), and Medicare tax (1.45 percent) continue to be withheld from overtime income just as they always have been. Your federal tax bill does not change because of this state exemption.
California's rules about how much employers must pay for overtime work also do not change. Employers must still pay time-and-a-half for hours beyond eight per day or 40 per week, and double-time for hours beyond 12 per day or for the eighth consecutive day of work. The exemption only removes the state income tax burden on that overtime pay — it does not change what your employer owes you.
Estimating Your Tax Savings
Your actual savings depend on how much overtime you work and your California tax bracket. California's state income tax ranges from 1 percent to 13.3 percent depending on your total income. If you earn $20 per hour and work five hours of overtime per week, you earn $100 per week in overtime income. At a 9.3 percent tax rate, that saves you roughly $9.30 per week, or about $480 per year.
The more overtime you work or the higher your income (and thus your tax bracket), the larger your savings. A worker in the highest bracket earning significant overtime will save substantially more. Use your 2024 tax return to estimate your bracket, then multiply your expected annual overtime income by your tax rate to get a rough figure.
Keep in mind this is a state tax savings only. Your federal tax liability on overtime income remains the same, so your total tax bill does not drop by the full state percentage.
Paycheck Changes You Might Notice
Starting January 1, 2025, your paycheck may look slightly different if you regularly work overtime. The gross pay (total earnings before taxes) stays the same, but the amount withheld for California state income tax should decrease. The line items for federal income tax, Social Security, and Medicare withholding do not change.
If you use your paycheck to budget or if you have set up automatic transfers based on your net pay, the increase in take-home pay might be noticeable. Some workers see a 1 to 3 percent increase in net pay depending on how much overtime they work. If your paycheck does not change on January 1, contact your payroll department to confirm they have updated their system.
Frequently Asked Questions
Do I have to do anything to get the overtime tax exemption?
No. If you are a W-2 employee, your employer handles it automatically starting January 1, 2025. If you are self-employed, you claim it on your 2025 tax return by separating overtime income from regular income before calculating your state tax.
Does the exemption explore to bonuses or commissions?
No. The exemption applies only to wages earned for hours worked beyond eight per day or 40 per week. Bonuses, commissions, and other forms of compensation are not considered overtime income under this exemption, even if you earned them during weeks when you also worked overtime hours.
What if I work in multiple states?
The exemption applies only to income you earned while working in California. If you work partly in California and partly in another state, only the California portion of your overtime income is exempt from California state tax. Your employer or tax return should separate income by state.
Can I claim this exemption for 2024 taxes?
No. The exemption begins January 1, 2025. Overtime income earned in 2024 remains subject to California state income tax. When you file your 2024 return in 2025, you do not claim this exemption.
Will my employer withhold too much tax before January 1?
Possibly, if your employer's payroll system is not updated before the new year. If you notice California tax withheld on overtime hours in late December 2024, keep documentation. You can claim a refund for any incorrect withholding when you file your 2024 return, though the amount is likely small for just a few days of pay.
