Overview: Schedule 1-A & OBBB Provisions
For tax year 2025, the IRS published Schedule 1-A and updated instructions to Form 1040 to implement critical portions of the One, Big, Beautiful Bill. These instructions detail how taxpayers can claim deductions for:
- Qualified tips (deductions for tips commonly and regularly received in certain occupations) (irs.gov)
- Qualified overtime pay (the portion of overtime that exceeds the regular rate) (irs.gov)
- Interest paid on qualified car loans for eligible passenger vehicles (irs.gov)
- Enhanced deduction for seniors (born before January 2, 1961), with phaseouts based on Modified Adjusted Gross Income (MAGI) (irs.gov)
What You Need to Know to Claim Them
1. Qualified Tips
- Tips must be received in an occupation listed under “customarily and regularly receive tips.”
- There are worksheets and occupation codes included in the instructions to help you determine eligibility and amount.
- You must report tips; payers don’t need to update W-2 or 1099 forms for 2025 but should provide info to taxpayers. (irs.gov)
2. Qualified Overtime Compensation
- Only the “premium” (e.g., the half-time portion of time-and-a-half) counts.
- Maximum deduction: $12,500 for individuals, $25,000 if married filing jointly.
- Phases out above MAGI of $150,000 (individual) or $300,000 (joint).
- If employer doesn’t separately report overtime premium, you may use a reasonable method to derive it using pay stubs or statements. (irs.gov)
3. Car Loan Interest Deduction
- Deduct interest on a qualified passenger vehicle loan used for personal use, not lease payments.
- Must meet criteria (vehicle assembled in U.S., personal use, etc.).
- Applies whether you itemize or use standard deduction. (irs.gov)
4. Seniors’ Enhanced Deduction
- For taxpayers born before Jan 2, 1961.
- If married filing jointly, both spouses must qualify.
- Enhanced deduction up to $6,000 per eligible person, phases out above certain MAGI thresholds. (irs.gov)
Actionable Steps for Taxpayers
- Gather all documents: pay stubs showing overtime, tip statements, loan interest payment statements.
- Use Schedule 1-A and new Form 1040 instructions. Multiple worksheets are provided for tips and overtime. (irs.gov)
- Check your MAGI early to estimate phaseout impacts.
- Keep good records even if forms aren’t updated for 2025—IRS allows alternative documentation where necessary. (irs.gov)
Example Scenario
Maria, a restaurant worker, earned $18,000 in tips in 2025. Her MAGI is $80,000. Since her occupation is listed, she can deduct up to $18,000 in qualified tips using Schedule 1-A—even if her employer didn’t mark them on W-2s separately—by using her pay statements and worksheets. If married filing jointly and both MAGI under $300,000, similar deductions apply.
Takeaway: Even without updated forms, taxpayers can nevertheless access new OBBB benefits in 2025 using Schedule 1-A—with careful recordkeeping and by following the new guidance to claim deductions properly.
