IRS Schedule 1-A Explained: How to Claim No Tax on Tips, Overtime & More

What Is Schedule 1-A?

Schedule 1-A is a new IRS attachment to Form 1040, introduced for the 2025 tax year (returns filed in spring 2026). It was created specifically to consolidate the four above-the-line deductions established by the One Big Beautiful Bill Act (OBBBA) into one standardized form.

Before Schedule 1-A existed, taxpayers had no single place to report these deductions. The IRS designed this form to bring all four OBBBA benefits under one roof, simplify auditing, and make it easier for tax software to handle the new rules consistently.

Schedule 1-A is an above-the-line deduction, meaning it reduces your Adjusted Gross Income (AGI) regardless of whether you itemize or take the standard deduction. That makes it particularly valuable: a lower AGI can unlock other tax benefits like the Earned Income Tax Credit and the Child Tax Credit.

The Four Deductions on Schedule 1-A

Schedule 1-A is divided into four parts, each corresponding to one OBBBA deduction. You only need to complete the parts that apply to your situation.

Part I: No Tax on Seniors

Part I provides an enhanced deduction for taxpayers age 65 or older. To qualify:

• You must be 65 or older by December 31, 2025
• Income limit: under $75,000 (single) or $150,000 (married filing jointly)
• The deduction is an additional amount on top of the standard deduction — not a replacement for it

This part is designed to provide meaningful relief to lower- and middle-income seniors on fixed incomes, many of whom rely heavily on Social Security.

Part II: No Tax on Tips

Part II is the most widely applicable section for service industry workers. It allows qualifying tipped workers to deduct up to $25,000 of tip income from federal taxable income. Requirements:

• Your occupation must be one that customarily and regularly receives tips (per IRS guidance — 68+ qualifying jobs)
• Income limit: under $150,000 (single) or $300,000 (married filing jointly) in total income
• Maximum deduction: $25,000 per year
• Tips must be fully reported as income on your return

Part III: No Tax on Overtime

Part III covers overtime pay earned by workers protected under the Fair Labor Standards Act (FLSA). Eligible workers can deduct their qualified overtime compensation from federal taxable income. Key rules:

• You must be a non-exempt employee under the FLSA (most hourly workers qualify; most salaried exempt employees do not)
• Income limit: under $150,000 (single) or $300,000 (married filing jointly)
• The deduction applies to the overtime premium — the extra 0.5x rate — not your entire overtime paycheck

Part IV: No Tax on Car Loans

Part IV allows taxpayers to deduct interest paid on domestic automobile loans — loans used to purchase vehicles assembled in the United States. Key details:

• Maximum deduction: $10,000 per year in loan interest
• The vehicle must be primarily for personal use
• The vehicle must meet the IRS definition of a "domestic auto" (assembled in the U.S. — check the window sticker or the NHTSA database)
• The loan must be a standard auto loan — leases do not qualify

Who Needs to File Schedule 1-A?

You must attach Schedule 1-A to your Form 1040 if you are claiming any of the four OBBBA deductions. You do not need to file Schedule 1-A if none of the four deductions apply to you — in that case, nothing changes about your return.

Specifically, you need Schedule 1-A if:

• You are 65+ with income under $75,000/$150,000 and want the seniors deduction (Part I)
• You earned tip income in a qualifying occupation and your total income is under $150,000/$300,000 (Part II)
• You earned FLSA-covered overtime pay and your income is under $150,000/$300,000 (Part III)
• You paid interest on a domestic auto loan and want to deduct it (Part IV)

If you qualify for multiple parts, you complete all relevant sections on the same Schedule 1-A. The totals from each part are combined on the last line of the form and carried to your Form 1040.

How to Fill Out Schedule 1-A: Step by Step

Step 1: Gather Your Documents

Before you sit down with Schedule 1-A, collect the following records:

• W-2 — Box 1 (total wages), Box 7 (Social Security tips), Box 8 (allocated tips), and any overtime pay reflected in your wages
• Tip records — daily tip log, employer tip reports, IRS Form 4070A, or gig platform earnings statements
• Overtime records — pay stubs showing hours worked and overtime pay separately, or a year-end earnings summary from your employer
• Auto loan statements — annual interest summary from your lender (often sent as Form 1098 or included with January statement)
• Vehicle documentation — proof the vehicle is a domestic auto (NHTSA Vehicle Identification Number lookup, or window sticker showing assembly location)

Step 2: Part II — Calculate Your Tip Deduction

On Part II of Schedule 1-A, you will enter your total qualified tip income for 2025. The starting point for most W-2 workers is W-2 Box 7 (Social Security tips). For workers with allocated tips (Box 8), you add those in as well.

Enter the lesser of your actual qualified tip income or $25,000. The form will not allow you to enter more than the cap. If you also have income from multiple jobs, combine all tip income across jobs — but the $25,000 cap applies to your total, not per employer.

Step 3: Part III — Calculate Your Overtime Deduction

On Part III, you enter your qualified overtime compensation. Your W-2 or pay stubs should show a breakdown of regular pay versus overtime pay. If your employer does not separately itemize overtime on the W-2, use your pay stubs to reconstruct the figure.

The deductible amount is the overtime premium — the additional 50% above your regular rate. For example, if your regular rate is $20/hour and you worked 200 overtime hours, your premium is $10/hour × 200 hours = $2,000 deductible (not the full $30/hour × 200 hours = $6,000). Confirm this interpretation with your tax software or a tax professional, as IRS guidance on the exact calculation method may be updated.

Step 4: Transfer the Total to Form 1040

Once you have completed all applicable parts, Schedule 1-A shows a total deduction amount on its final line. This figure is carried to Schedule 1 (Form 1040), Part II as an adjustment to income. From there it flows to Form 1040, Line 10, reducing your AGI on Line 11.

Keep a copy of your completed Schedule 1-A and all supporting documents for at least three years from your filing date in case of an IRS inquiry.

Filing with Tax Software

All major tax software platforms have been updated for the 2025 tax year to support Schedule 1-A and all four OBBBA deductions.

TurboTax

TurboTax handles Schedule 1-A through its guided interview. In the Deductions & Credits section, you will find prompts for each OBBBA deduction. TurboTax auto-populates tip amounts from your imported W-2 data and asks qualifying questions to determine eligibility for each part. The completed Schedule 1-A is generated automatically in the background.

H&R Block

H&R Block walks you through the OBBBA deductions during the income and deductions interview. It asks about your occupation (for tip qualification), FLSA status (for overtime), and auto loan details. Each section maps directly to the corresponding part of Schedule 1-A.

FreeTaxUSA

FreeTaxUSA supports Schedule 1-A in its free federal filing tier. Navigate to Adjustments to Income and look for the OBBBA Deductions section. Unlike TurboTax, FreeTaxUSA does not auto-import W-2 data, so enter your tip and overtime amounts manually. Confirm that the amounts appear correctly on the Schedule 1-A preview before submitting.

Filing by Paper

Download Schedule 1-A directly from IRS.gov. Complete each applicable part, attach it behind your Form 1040, and mail to the address listed in your Form 1040 instructions for your state. Allow extra processing time when filing by paper — the IRS typically takes 6–8 weeks longer to process paper returns versus e-filed returns.

Common Mistakes to Avoid

1. Not Reporting Tips but Trying to Deduct Them

Schedule 1-A requires that tip income be fully reported as income before the deduction applies. You cannot skip reporting cash tips on your return and then claim a deduction for them. The IRS cross-references W-2 Box 7 and employer tip reports — discrepancies flag returns for review.

2. Exceeding the $25,000 Cap on Tips

The tip deduction is hard-capped at $25,000. If you earned $35,000 in tips, only $25,000 is deductible. The remaining $10,000 is taxed as ordinary income. Tax software enforces this automatically, but double check the Part II line before submitting.

3. Confusion About FICA — It Still Applies

Schedule 1-A reduces your federal income tax only. Social Security (6.2%) and Medicare (1.45%) taxes still apply to all tip and overtime income. Misunderstanding this leads some workers to under-withhold for FICA, resulting in a surprise bill. Use our Paycheck Calculator to verify your net withholding covers both income tax and FICA.

4. Filing Schedule 1-A When Income Exceeds the Limits

If your total income is above $150,000 (single) or $300,000 (married filing jointly), you do not qualify for the tips or overtime deductions on Parts II and III. Filing Schedule 1-A with ineligible amounts can trigger an IRS notice or audit. Use our Schedule 1-A Calculator to confirm eligibility before filing.

5. Missing the Car Loan Domestic-Auto Requirement

Part IV only applies to vehicles assembled in the United States. A foreign-brand vehicle manufactured in a U.S. plant may qualify; a U.S.-brand vehicle assembled overseas does not. Check the country of final assembly on your vehicle's window sticker or the NHTSA VIN decoder before claiming this deduction.
