OBBBA Tax Deduction FAQ

The short answer: Most people get this wrong: "no tax on overtime" never made overtime tax-free — it is a deduction for the premium half of your OT pay, worth your marginal rate, claimed on the new Schedule 1-A, and only for W-2 hourly workers earning under $150k single / $300k joint.

Answers to common questions about the One Big Beautiful Bill Act tax deductions.

Can I claim both overtime and tips deductions?

Yes. They are separate deductions. You can claim both on the same return, up to $12,500/$25,000 for overtime and $25,000 for tips.

Does "no tax on overtime" mean my overtime is tax-free?

No. Only the premium portion (extra 0.5×) is deductible, and only up to $12,500/$25,000. FICA taxes still apply to all wages including overtime.

I'm self-employed. Do I qualify for overtime or tips deductions?

It depends on which one. The overtime deduction is W-2 only — 1099 and self-employed income does not qualify. The tips deduction, however, can be claimed by self-employed tipped workers (limited to the net income of that specific business), as long as the tips were reported on a 1099 or your return.

How much of my overtime pay do I actually get back?

Your savings equal the premium portion × your marginal tax rate — never the full overtime check. In the 22% bracket, every dollar of qualified OT premium returns 22 cents of federal income tax; FICA (7.65%) is not refunded. See the overtime calculator page for a full breakdown.

What is 'OB' or 'OBB' on my W-2 Box 14?

Employers use Box 14 (an informational box) for amounts that don't fit standard boxes. Labels like 'OB', 'OBB', or 'OT Prem' typically refer to OBBBA-related amounts — often qualified overtime premium or reported tips. For 2025 most employers are not required to break these out separately, so Box 14 codes vary by payroll provider. Our W-2 reporting guide lists common labels.

What form do I use to claim these deductions?

IRS Schedule 1-A, filed with Form 1040, starting tax year 2025. This is a new form created specifically for OBBBA deductions.

Does my state honor these deductions?

State conformity varies. This calculator only estimates federal savings. Check your state's tax authority for conformity rules.

How do I find my overtime premium amount?

Check W-2 Box 14 (look for 'OT Pay' or 'OT Premium'), your final 2025 paystub, or ask your payroll department. For 2026+, employers must report it on your W-2.

Is the senior deduction in addition to the standard deduction?

Yes. It is an additional deduction on top of the standard or itemized deduction. If both spouses are 65+, each can claim $6,000.

Does the car loan deduction apply to used cars?

No. It applies to loans for new vehicles assembled in the United States. Check your VIN to confirm assembly location.

What happens after 2028?

These deductions are scheduled to expire after tax year 2028 unless extended by Congress.

Can I amend a prior-year return to claim these?

No. These deductions only exist starting tax year 2025. They cannot be claimed on older returns.

Are these deductions or credits?

They are deductions — they reduce your taxable income, not your tax bill directly. The actual tax savings equals the deduction amount multiplied by your marginal tax rate.

Can I claim the car loan interest and overtime deduction if I'm above the income limit?

Each deduction has its own income limits. The car loan deduction phases out at lower incomes ($100K/$200K) than overtime/tips ($150K/$300K). Check each calculator to see if you qualify.

Will these deductions change my paycheck withholding in 2026?

Possibly, and in your favor. The IRS released updated 2026 withholding tables, but they spread the OBBBA deductions unevenly across incomes — many moderate earners will be over-withheld. If you claim overtime, tips, or the senior deduction, check the W-4 Withholding Adjuster to see whether filing a new W-4 gets the money into your paychecks instead of your refund.

Does the $40,000 SALT cap affect these deductions?

No, they are separate lines. The OBBBA raised the state and local tax deduction cap from $10,000 to $40,000 starting in 2025 (with its own income phase-out above $500,000 MAGI). SALT is an itemized deduction; the overtime/tips/senior/car-loan deductions are above-the-line. You can benefit from both — see the SALT cap calculator.

Can I claim the senior deduction and the overtime deduction in the same year?

Yes. Each OBBBA deduction is independent — a 66-year-old hourly worker can claim the $6,000 senior deduction and the overtime premium deduction on the same Schedule 1-A. Nothing in the statute makes claiming one disqualify the others.

Do these deductions apply to my 2025 return or my 2026 paychecks?

Both, differently. You claim the deductions on your 2025 federal return (filed in early 2026) using paystub or W-2 Box 14 evidence. During 2026, employers must report qualified overtime separately on the W-2, and updated withholding tables apply — so the benefit starts showing up in paychecks during the year, not only at refund time.
