## Understanding the Key Changes Under the One, Big, Beautiful Bill (OBBB)
The OBBB introduced sweeping changes that primarily come into effect for **tax year 2026**—when you file returns in 2027. These changes are inflation-adjusted amounts for tax rate brackets, standard deductions, and various credits and exemptions.

Notable changes include:
- **Standard deduction increases**: married filing jointly rises to $32,200; single filers to $16,100; heads of households to $24,150.

- **Earned Income Tax Credit (EITC)** maximum for 3+ qualifying children goes up to $8,231. ([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))
## Tax Planning Strategies You Can Use Now
1. **Adjust Withholding and Estimated Taxes**
Many of these changes are retroactive to the **start of 2025**. Owing to this timing, withholding schedules and estimated tax payments might be off, resulting in unexpected underpayment or refunds. ([irs.gov](https://www.irs.gov/newsroom/taxpayers-could-see-a-change-in-their-2025-tax-bill-or-refund?utm_source=openai))
2. **Maximize New Deductions and Credits**
- Seniors aged 65 or older get an additional **$6,000 deduction ($12,000 if married filing jointly)**. ([irs.gov](https://www.irs.gov/newsroom/2026-filing-season-updates-and-resources-for-seniors?utm_source=openai))
- Deductions have been introduced or expanded for overtime, tip income, adoption, and certain vehicle loan interest. ([irs.gov](https://www.irs.gov/newsroom/taxpayers-could-see-a-change-in-their-2025-tax-bill-or-refund?utm_source=openai))
3. **Use the Inflation Raises in Brackets**
Higher brackets and vaccination of phase-outs help low and mid-income taxpayers. Understanding where these thresholds have shifted matters for deciding whether to accelerate income, defer deductions, or time capital gains/losses.
4. **Plan Around Business Asset Purchases**
The allowance for 100% first-year depreciation on qualifying business property bought and placed into service after Jan. 19, 2025, gives eligible businesses major ability to boost write-offs. ([irs.gov](https://www.irs.gov/newsroom/one-big-beautiful-bill-provisions?utm_source=openai))
## Examples and Actionable Moves
- **Example for Seniors**: If you're age 65 or older, filing jointly, with AGI below $150,000, you can claim the additional senior deduction. Review whether itemizing still makes sense compared to the higher standard deduction.
- **Small Business Equipment Investment**: For business owners, accelerating a purchase into 2025 could allow you to claim full cost immediately rather than depreciating over years. Confirm your purchase date and usage date.
- **Adoption Credit Usage**: Families expecting to finalize adoption should monitor the refundable portion of the adoption credit, now $5,120 for tax year 2026, and assess whether expenses occur in eligible periods.
## Bottom Line
The inflation-adjusted changes under the OBBB provide meaningful opportunities to **lower effective tax rates and increase deductions and credits**, especially for seniors, families with children, and small businesses. But because many provisions are retroactive to 2025, planning now—adjusting withholdings, timing expenses and income—can pay off. Leveraging the full scope of these changes requires reviewing your entire tax profile with an eye toward timing, eligibility, and documentation.
