Key findings

  • 196 published ordinary-income bracket rows in the IRS Revenue Procedure corpus (7 tax years × 4 filing statuses × 7 rates). Every row is in the downloadable CSV.
  • $16,100 is the 2026 Single standard deduction, versus $12,400 in 2020 (+29.8%). Married filing jointly is exactly 2× at $32,200.
  • #1/7 of published years by Single standard deduction (highest dollars = #1). The same year ranks #5 of 6 year-over-year pairs by Single 37% threshold inflation lift (+2.3%). They diverge: 2023 is #1 of 6 on the inflation-lift map (+7.1%).
  • +23.6% is how far the Single 37% threshold moved from $518,400 in 2020 to $640,600 in 2026. The standard deduction rose faster (+29.8%) over the same span.
  • 1.20× is the 2026 Married-filing-jointly 37% threshold ($768,700) relative to Single ($640,600). The 10% band is exactly 2× ($24,800 / $12,400). The 2× rule breaks at the top rate.
  • $2,000 additional standard deduction for age 65+ Single stayed flat from 2025 to 2026 (still $2,000). The ordinary Single deduction rose $350 (+2.2%) in that same year.
  • +7.1% Traditional / Roth IRA elective-deferral ceiling, $7,000 → $7,500. That is larger than the same-year Single standard-deduction lift (+2.2%).
  • 1.5× Head of Household vs Single standard deduction in 2026 ($24,150 / $16,100). In 2020 the same ratio was 1.504× ($18,650 / $12,400).
