IRS Announces Major 2026 Tax Adjustments Under One Big Beautiful Bill Act
The IRS has announced sweeping 2026 tax changes driven by the One Big Beautiful Bill Act (OBBBA), including permanent seven-rate brackets, higher standard deductions, a temporary senior deduction, and larger estate and AMT thresholds that affect millions.
- Seven-rate brackets permanent: TCJA-era rates (10%–37%) locked in and inflation-adjusted for 2026 (Fox Business, H&R Block, congressional text).
- Higher deductions and thresholds: Standard deduction rises to $16,100 (single) / $32,200 (joint); top 37% bracket thresholds and estate exclusion increased (IRS, Fox Business).
- Targeted senior relief: Temporary additional deduction up to $6,000 (single) / $12,000 (joint) through 2028 with MAGI phase-outs (CBS News).
What changed and why it matters
Overview: The IRS combined routine inflation indexing with policy changes from the One Big Beautiful Bill Act (OBBBA) to lock in the seven-rate structure from the Tax Cuts and Jobs Act and raise many thresholds. That means more take-home pay for many taxpayers relative to 2025 thresholds, while permanently removing a legislative decision point for those expiring provisions.
Tax brackets and top-rate thresholds
OBBBA makes seven tax rates permanent: 10%, 12%, 22%, 24%, 32%, 35%, 37%. For 2026 the top 37% marginal rate applies at incomes over $640,600 for single filers and $768,700 for married couples filing jointly, protecting many upper-middle-income households from inflation-driven bracket creep (Fox Business).
Standard deduction and exemptions
2026 standard deduction: $16,100 for single filers, $32,200 for joint filers, and $24,200 for head-of-household. OBBBA cements these amounts and indexes them to inflation. The personal exemption remains largely eliminated for most taxpayers, with limited carve-outs and phased provisions tied to age and income (H&R Block, congressional text).
Senior tax relief 2026: what retirees should know
Temporary deduction for seniors: Taxpayers aged 65+ may claim an extra deduction up to $6,000 (single) or $12,000 (joint). The benefit phases out above $75,000 (single) and $150,000 (joint) MAGI and is set to expire after 2028. Eligibility depends on modified adjusted gross income and filing details—retirees should consult advisers to optimize Social Security timing and distribution strategies (CBS News).
Estate planning, AMT and business-related changes
Estate tax exclusion: The unified estate tax exclusion increases to $15 million for deaths in 2026 (up from $13.99 million in 2025), affecting high-net-worth planning strategies. AMT exemptions are raised to $90,100 (individuals) and $140,200 (married couples), with phase-outs beginning at $500,000 and $1 million, respectively. Business owners and wealthy families should consult estate attorneys and tax advisers promptly (Fox Business, IRS newsroom).
Credits and targeted employer provisions
Several credits shift in 2026: the adoption tax credit increases to $17,670 with up to $5,120 refundable, and the employer-provided childcare credit caps rise to $500,000 (or $600,000 for certain small businesses). These changes could encourage employers to expand childcare benefits and affect working families’ budgets (Fox Business).
Phase-outs and MAGI limits
OBBBA tightens or introduces phase-outs tied to modified adjusted gross income (MAGI) for certain deductions and credits. Benefits like the working Americans and seniors deduction become unavailable beyond specified MAGI thresholds. Taxpayers near those limits should reassess withholding and year-end planning to avoid surprises (IRS newsroom).

Implications for California
Economic impact: Higher standard deductions and senior relief may improve household cash flow for many Californians, helping offset high living costs. But permanent brackets and larger estate exclusions could affect long-term federal revenue and downstream funding Californians rely on.
Retirees & seniors: With a large retiree population, California may see meaningful uptake of the temporary senior deduction through 2028, particularly among lower- and middle-income seniors who meet AGI limits. Review Social Security timing and IRA decisions with a tax professional (CBS News).
Small businesses & employers: Employers offering childcare may benefit from the higher credit caps, which could increase workforce participation for parents; consult advisors on payroll and benefits eligibility (Fox Business).
Estate planning: The increased estate exclusion gives breathing room, but state-level rules vary—wealthy families and business owners should consult estate attorneys and tax advisers immediately.
Housing and real estate: Higher standard deductions mean fewer filers may itemize, which can change mortgage interest and property tax strategies and timing for capital gains planning.
Practical steps for Californians
- Review withholding: Use updated IRS tables and consult a tax consultant to adjust withholding to 2026 thresholds (IRS newsroom).
- Reassess retirement distributions: Seniors should discuss RMDs, IRA conversions and Social Security claiming strategies with financial and tax advisors (CBS News).
- Update estate & business plans: Consult estate attorneys and tax accountants about the larger estate exclusion and AMT adjustments (Fox Business).
- Check credits: Employers and families should verify eligibility for the adoption credit and employer-provided childcare credit to plan for 2026 (Fox Business).
What taxpayers should do next
