Understanding Your New Deductions Under the OBBB
The One, Big, Beautiful Bill (OBBB) introduces several fresh deductions for tax year 2025, now clarified by Schedule 1-A and updated instructions. If you receive tips, earn overtime compensation, paid interest on car loans, or are a senior taxpayer, these deductions could significantly reduce your taxable income—even if you take the standard deduction. Here’s how.
Who Qualifies and What Limits Apply
| Deduction Type | Who Can Claim It | Cap / Phase-Outs | Must File Joint Returns? |
|---|---|---|---|
| Tips | Workers who customarily receive tips and properly report them | Up to $25,000; beginning to phase out at MAGI over $150,000 (or $300,000 MFJ) | Yes for married couples |
| Overtime | Earned under FLSA, exceeding regular rate | Up to $12,500 (or $25,000 MFJ); phase-out similar thresholds | Yes if married |
| Car Loan Interest | Qualified passenger vehicle loans; final assembly in US | Terms defined; maximum deduction based on car loan interest expense; applies to both give standard or itemize | Depends on filing status |
| Senior Enhanced Deduction | Taxpayer (and spouse if MFJ) born before Jan 2, 1961 with valid SSN | $6,000 per person; $12,000 MFJ; reduced if MAGI > $75,000 (or $150,000 MFJ) | Yes if MFJ |
How to Calculate and Claim These Deductions
- Use Schedule 1-A with your 2025 Form 1040: This new schedule was released March 2, 2026, and provides worksheets and examples. (irs.gov)
- For tips: report all tips; use worksheets to distinguish qualified tips. Only amounts exceeding reporting thresholds count.
- For overtime: use only amounts paid as required by FLSA meaning overtime over standard hours paid at at least 1.5× regular rate. Do not include bonuses disguised as overtime.
- For car loan interest: only “qualified passenger vehicle” interest counts—vehicles must meet definitions (assembly, usage, income threshold). Keep documentation from lender.
- For senior deduction: verify birth dates, SSNs. Enhanced deduction is allowed regardless of standard deduction vs itemizing.
Examples to Illustrate
- Single tipped worker earning MAGI $140,000 with $30,000 in tips: qualifies; tip deduction max $25,000; MAGI under phase-out threshold.
- Married couple filing jointly, both seniors with valid SSNs, MAGI $160,000: eligible but enhanced senior deduction reduced due to exceeding $150,000 threshold.
- Solo gig worker with 150 transactions via payment app but total gross payments $15,000: does not trigger backup withholding under proposed OBBB regs, because neither threshold (transactions >200 and payments >$20,000) is met. (irs.gov)
Action Plan for 2025 Tax Return Preparation
- Gather proof: tip logs, pay stubs showing overtime, loan interest statements for cars, birth certificates and SSN for senior status.
- Choose standard deduction or itemize—deductions above work both ways.
- Use updated tax software or IRS fillable forms that include Schedule 1-A.
- For taxpayers using third-party platforms, monitor transactions to understand if backup withholding may apply (once proposed regs become final) to avoid surprises.
Bottom Line: These OBBB deductions are designed to help workers, seniors, and everyday taxpayers reduce their tax burden—even without itemizing. With thoughtful preparation and solid documentation, many taxpayers can benefit significantly.
