IRS reveals 2026 tax adjustments, One Big Beautiful Bill Act makes major changes to brackets and deductions
The IRS unveiled its 2026 tax adjustments, combining routine inflation indexation with permanent changes from the One Big Beautiful Bill Act, including revised tax‑bracket thresholds and larger standard deductions that will affect taxpayers and planners nationwide.
- Combined adjustments: 2026 updates mix inflationary indexing with lasting policy changes from H.R.1 (IRS newsroom).
- Top rate unchanged: The 37% top marginal rate remains, now applying above $640,600 (single) and $768,700 (married filing jointly) — per Fox Business.
- Higher standard deduction: Standard deduction rises to $16,100 (single) and $32,200 (married filing jointly), reflecting inflation and legislative change (H.R.1; Fox Business).
- New and temporary credits: OBBBA creates deductions and credits for working Americans and seniors, and includes temporary senior relief through 2028 (IRS newsroom).
What the IRS announced — bracket and deduction changes
The IRS’s autumn update aligns tax thresholds with inflation and incorporates statutory changes enacted by Congress. These “IRS 2026 tax adjustments” are intended to limit bracket creep — when inflation pushes taxpayers into higher rates without real income gains (CBS News).

2026 standard deduction and personal exemptions
The 2026 standard deduction increases to $16,100 for single filers and $32,200 for married filing jointly — an inflation‑driven increase from 2025 levels (Fox Business; H.R.1).
Under OBBBA, the seven‑bracket system introduced by the 2017 tax law (TCJA) is now permanent (10%, 12%, 22%, 24%, 32%, 35%, 37%), while most personal exemptions remain largely eliminated, with limited senior relief (H&R Block; IRS newsroom).
Permanent law changes from the One Big Beautiful Bill Act
The One Big Beautiful Bill Act (H.R.1) enacted several lasting tax shifts now reflected in the 2026 adjustments:
- It makes the seven‑bracket rate structure permanent. (H.R.1; H&R Block)
- It eliminates most personal exemptions. (H&R Block)
- It creates new deductions and credits for working Americans and seniors, and raises certain caps such as the employer‑provided childcare credit. (IRS newsroom; Fox Business)
Senior relief and temporary deductions
OBBBA includes temporary relief for older taxpayers. Seniors 65 and over may claim a temporary deduction up to $6,000 if their AGI is ≤ $75,000 (single) or ≤ $150,000 (couples). This provision is temporary and set to expire in 2028 (CBS News; IRS newsroom).
Estate tax and credits
- Estate tax exclusion: Rises to $15 million for decedents who die in 2026 (up from about $13.99 million in 2025), affecting high‑net‑worth estate planning (Fox Business).
- Adoption tax credit: Maximum increases to $17,670 for 2026, with a refundable portion of $5,120. (Fox Business)
AMT, employer credits, and other adjustments
- AMT exemptions: Set at $90,100 (single) and $140,200 (married); phase‑outs begin at $500,000 and $1 million, respectively. (Fox Business)
- Employer childcare credit caps: Increase from $150,000 to $500,000 (or $600,000 for eligible small businesses), which may expand workplace childcare offerings. (Fox Business)
- New broader deductions: OBBBA creates broader deductions for working Americans and seniors, including an annual maximum of $12,500 for individuals or $25,000 for joint filers, with phaseouts for higher earners (IRS newsroom).
Why these changes matter now
Annual inflation adjustments limit bracket creep; in 2026 those routine updates arrive alongside substantive policy shifts from OBBBA. Together they can materially change taxpayers’ liabilities, planning strategies, and the predictability of long‑term tax rules (H&R Block; Congress.gov).
Questions taxpayers should ask now
- Will the higher 2026 standard deduction reduce my taxable income compared with 2025? (See the 2026 standard deduction figures above and Fox Business.)
- Do I qualify for the temporary senior deduction or the new working deductions under OBBBA? (See IRS guidance.)
- Does the higher estate tax exclusion change my estate plan? (See H.R.1 and related analysis.)
Implications for San Luis Obispo, California
Economic impact
Many households in San Luis Obispo may see reduced federal liabilities due to higher standard deductions and inflation indexing. Moderate‑income families and single filers who use the standard deduction could benefit most. Local small businesses offering employee childcare may also gain from increased employer credit caps (Fox Business; IRS newsroom).
Political consequences
Making the seven‑bracket system permanent and changing deductions could shape local debates about taxes and services. San Luis Obispo officials should expect constituents to seek clarity on who benefits and who faces more complexity (Congress.gov; H&R Block).
Social effects
Seniors in San Luis Obispo who qualify for the temporary $6,000 deduction may see meaningful relief. Nonprofits and senior service providers should prepare to advise older clients on eligibility and timing before the provision expires in 2028 (CBS News; IRS newsroom).
Cultural and housing relevance
Rising estate‑tax exclusion levels may influence estate planning and high‑value real estate transactions locally. Agricultural landowners and family estates in San Luis Obispo County should review plans with advisors given the new $15 million exclusion for 2026 (Fox Business).
Practical steps for residents
- Review withholding and estimated payments: If your income rose with inflation, update withholding to align with 2026 brackets (IRS newsroom; CBS News).
- Consult a tax professional: Local tax advisors can translate the 2026 adjustments into tailored actions for filing status, credits, and long‑term plans (IRS newsroom; H&R Block).
