What are the Key Inflation Adjustments under OBBB for Tax Year 2026
The One, Big, Beautiful Bill (OBBB) introduced inflation-indexed updates affecting over 60 U.S. tax provisions. Important changes include:
- The standard deduction for married filing jointly increased to $32,200, for single and married filing separately to $16,100, and for heads of households to $24,150. (irs.gov)
- Alternative Minimum Tax (AMT) exemption is now $90,100 for unmarried individuals (phasing out at $500,000) and $140,200 for married filing jointly. (irs.gov)
- Foreign Earned Income Exclusion (FEIE) rises to $132,900. (irs.gov)
- Estate Tax Exclusion Amount is now $15,000,000 for decedents in 2026. (irs.gov)
- Enhanced credits such as Adoption Credit (max expenses creditable up to $17,670; refundable portion $5,120) and higher limit for Employer-Provided Childcare Tax Credit (max from $150,000 to $500,000 or $600,000 for small business). (irs.gov)
How Families Should Adjust Their Tax Planning
- Reevaluate withholdings or estimated payments: With higher standard deductions and expanded credits, many taxpayers may face lower taxes owed, so updating paycheck withholding might prevent over-payment.
- Use FEIE wisely for overseas income: Families living abroad or with income from foreign sources may see increased benefit; if your income barely exceeds new thresholds, consider timing income or recognizing deductions carefully.
- Estate planning recalibration: Those expecting large estates need to revisit their estate planning, as the exclusion went up significantly—potentially enabling larger gifts or transfers without triggering federal estate tax.
- Childcare and adoption cost timing: If adoption costs or childcare expenses are planned around taxable events, aligning timing to benefit from increased credit maxima can increase savings.
Practical Examples
Scenario A – Family Abroad: Maria lives in Costa Rica with her husband and two kids. She earns $130,000 abroad. Under the new FEIE, her foreign earned income exclusion is $132,900—so she may fully exclude her salary. However, she should ensure she qualifies (bona fide residence or physical presence tests) to rely on FEIE.
Scenario B – Estate Planning: The Johnsons expect to pass down $14 million estate to their children. Under 2025 thresholds, more would be taxable; with the $15 million exclusion in 2026, their estate might fall below taxable threshold—presenting opportunity to revise gift giving strategies.
Actionable Steps Going Forward
- Review your 2025 tax return outcomes and simulate 2026 with updated thresholds to see where your liabilities shift.
- Ensure paychecks reflect new standard deduction and tax rate thresholds—using updated IRS withholding estimator.
- For cross-border families, confirm eligibility for FEIE or foreign tax credits; seek advice on dual taxation treaties.
- Update estate and gifting strategy, possibly executing gifts before thresholds change or aligning with new limits.
Conclusion: The inflation adjustments under OBBB for 2026 create real opportunities for families to reduce tax liabilities. Being proactive—adjusting withholding, aligning income timing, and updating estate plans—will maximize benefits.
