What changed for tax brackets and rates
The IRS shifted income thresholds upward to reflect inflation. The top marginal rate remains 37%, with bracket thresholds set for 2026 as follows:
- 37% — single filers over $640,600; married filing jointly over $768,700
- 35% — singles at $256,225; married at $512,450
- 32% — singles at $201,775; married at $403,550
- 24% — singles at $105,700; married at $211,400
- 22% — singles at $50,400; married at $100,800
- 12% — singles at $12,400; married at $24,800
- 10% — income below the 12% thresholds
Why this matters: Indexing helps prevent bracket creep, so wage increases tied to inflation don’t automatically push taxpayers into higher effective tax rates.
Standard deductions and personal exemptions
For tax year 2026 the standard deduction increases to $16,100 for single filers and $32,200 for married couples filing jointly, up from $15,750 and $31,500 respectively in 2025 (H&R Block; Fox Business).
The OBBBA maintains the seven-bracket structure established under the TCJA. Personal exemptions largely remain eliminated, though special provisions exist for certain seniors.
Credits, exclusions and other changes
- Estate tax: Exclusion increases to $15 million for decedents who die in 2026 — up from $13.99 million in 2025 (Fox Business).
- Adoption credit: Maximum credit rises to $17,670 with a refundable portion of $5,120 for 2026, helping offset adoption-related expenses (Fox Business).
- Alternative Minimum Tax (AMT): Exemption set at $90,100 for individuals; phaseouts begin at $500,000 (individuals) and $1 million (married filing jointly) (Fox Business).
- Childcare & employer credits: Employer-provided childcare tax credit caps raised—from $150,000 to $500,000, or up to $600,000 for qualifying small employers—aimed at encouraging employer-supported childcare (Fox Business).
- Seniors: Temporary tax deduction up to $6,000 is available through 2028 for taxpayers 65+ with AGI ≤ $75,000 (single) or ≤ $150,000 (joint), providing targeted relief (CBS News).
How the One Big Beautiful Bill Act (OBBBA) plays in
The OBBBA codified several lasting changes that shape the IRS adjustments, reinforcing the seven-bracket system from the TCJA and recalibrating select credits and limits. Analysts describe the law as aiming to balance inflation relief with targeted support for families and seniors (H&R Block).
Implications for San Diego, California
Economic impact
- Households may see modest changes in take-home pay or refunds as thresholds and the standard deduction rise—beneficial for middle-income families who do not itemize.
- Small employers offering childcare could find new credits more financially viable, especially for service-sector and biotech employers supporting families.
Political consequences
- Changes favoring seniors and working families may reduce local pressure to expand certain social services; San Diego’s large retiree base may welcome the temporary senior deduction.
- City and state leaders may reassess local tax relief programs in light of increased federal deductions and credits.
Social effects
- Seniors on fixed incomes may experience reduced financial stress due to the temporary deduction, helping with housing and healthcare costs (CBS News).
- Families pursuing adoption could benefit from the higher adoption credit, offsetting legal and medical expenses (Fox Business).
Cultural relevance
San Diego’s community priorities—family support services, veteran care and retiree networks—align with many of the targeted federal changes, particularly childcare support and senior relief.
Practical applications for residents
- Tax planning: Review withholding and retirement contributions now to avoid surprises when brackets change in 2026.
- Itemize vs. standard: With higher standard deductions, many taxpayers should estimate both options to determine which lowers their tax bill (H&R Block).
- Small employers: Evaluate whether the expanded childcare credit caps make onsite or subsidized childcare affordable.
- Estate planning: High-net-worth individuals should consult estate attorneys given the $15 million exclusion for 2026 (Fox Business).
