## Overview of the One, Big, Beautiful Bill Act (OBBBA)
Signed into law on July 4, 2025, the OBBBA introduced sweeping changes to U.S. individual and business taxation that affect tax years beginning in 2025 and 2026. Key items include inflation adjustments, new **deductions for both itemizers and non-itemizers**, and expanded credits.([irs.gov](https://www.irs.gov/newsroom/irs-releases-tax-inflation-adjustments-for-tax-year-2026-including-amendments-from-the-one-big-beautiful-bill?utm_source=openai))
## Key Deductions to Watch for Tax Years 2025–2026
These deductions are significant—they can often be used even if you take the standard deduction.
| Deduction | Amount | Phase-out Thresholds | Eligible Taxpayers |
|---|---|---|---|
| Additional deduction for seniors (65 or older) | **$6,000** single / **$12,000** married if both spouses 65+ | Begins to phase out at MAGI $75,000 (single), $150,000 (joint) | Available to non-itemizers and itemizers.([irs.gov](https://www.irs.gov/forms-pubs/how-to-update-withholding-to-account-for-tax-law-changes-for-2025?utm_source=openai)) |
| Qualified overtime compensation deduction | Up to **$12,500** individual / **$25,000** married filing jointly | Phases out over the same thresholds | Must have overtime required under Fair Labor Standards Act; only the “time-and-a-half” portion above regular rate counts.([irs.gov](https://www.irs.gov/forms-pubs/how-to-update-withholding-to-account-for-tax-law-changes-for-2025?utm_source=openai)) |
| Qualified automobile loan interest | Up to **$10,000** annually for passenger vehicle loan interest | Phase-out begins at MAGI $100,000 (single), $200,000 (joint) | Vehicle must be a new vehicle, assembled in U.S.; lease payments do not qualify.([irs.gov](https://www.irs.gov/forms-pubs/how-to-update-withholding-to-account-for-tax-law-changes-for-2025?utm_source=openai)) |
| State and Local Tax (SALT) cap increase | From $10,000 to **$40,000** ($20,000 if married filing separately) | Reduced if MAGI exceeds $500,000 (single), $250,000 (married separately) | Only for itemizers. Makes SALT deduction relevant again for many in high-tax states.([irs.gov](https://www.irs.gov/newsroom/irs-releases-tax-inflation-adjustments-for-tax-year-2026-including-amendments-from-the-one-big-beautiful-bill?utm_source=openai)) |
## Inflation Adjustments You Shouldn’t Overlook
These annual updates also change your tax planning calculus:
- **Standard deduction** for 2026: $32,200 (married filing jointly), $24,150 (head of household), $16,100 (single).([irs.gov](https://www.irs.gov/newsroom/irs-releases-tax-inflation-adjustments-for-tax-year-2026-including-amendments-from-the-one-big-beautiful-bill?utm_source=openai))
- **Foreign Earned Income Exclusion (FEIE)**: Increased to $132,900 in 2026.([irs.gov](https://www.irs.gov/newsroom/irs-releases-tax-inflation-adjustments-for-tax-year-2026-including-amendments-from-the-one-big-beautiful-bill?utm_source=openai))
- **Alternative Minimum Tax (AMT) exemption amounts**, thresholds, estate tax exclusion, childcare credits, etc., have all been indexed upward.([irs.gov](https://www.irs.gov/newsroom/irs-releases-tax-inflation-adjustments-for-tax-year-2026-including-amendments-from-the-one-big-beautiful-bill?utm_source=openai))
## Practical Tips: Planning and Implementation
1. **Review your tax withholding now**: Since many deductions are available retroactively to 2025 (e.g., overtime, vehicle loan interest, senior deduction), update your **Form W-4** to reflect anticipated changes to avoid under-withholding penalties.([irs.gov](https://www.irs.gov/forms-pubs/how-to-update-withholding-to-account-for-tax-law-changes-for-2025?utm_source=openai))
2. **Track eligible expenses carefully**: Keep records of overtime pay (time-and-a-half portions), vehicle loan interest, and other new deductions. Vehicle titles and final assembly documentation will matter.([irs.gov](https://www.irs.gov/forms-pubs/how-to-update-withholding-to-account-for-tax-law-changes-for-2025?utm_source=openai))
3. **Non-itemizers, take note**: Deductions for tips, overtime, car loan interest, senior status – even if you don’t itemize — can provide value.([irs.gov](https://www.irs.gov/forms-pubs/how-to-update-withholding-to-account-for-tax-law-changes-for-2025?utm_source=openai))
4. **Plan for phase-outs**: If your MAGI approaches or exceeds phase-out thresholds, model your options. Sometimes “bunching” deductions into 2025 or 2026 may offer more relief.
5. **Use updated resources**: Guide your strategy using the IRS **Publication 15-T** (2026) for withholding tables and **IRS Tax Tip 2026-20** to see how refunds/bills may change.([irs.gov](https://www.irs.gov/publications/p15t?utm_source=openai))
## Example: Making It Work
• Jane, age 67, married filing jointly, MAGI $80,000, lives in New York. She works overtime and has a passenger vehicle with a U.S.-assembled new vehicle loan.
• Under OBBBA, she can claim: the **senior deduction** of $12,000 + **overtime deduction**, plus up to **$10,000 in car loan interest**. Also, because her state and local taxes are high, the SALT cap increase to $40,000 allows her to claim itemized deduction where under prior law she might have been forced to take standard deduction.
• Jane recalculates withholding via updated W-4 and avoids a large tax bill when filing.
## Takeaway
OBBBA reshapes the deduction landscape—especially for seniors, remote workers, and people in high-tax jurisdictions. Whether you itemize or rely on the standard deduction, several of these new deductions and inflation adjustments can save you money. Start planning now for both your 2025 return and your strategies in 2026.
