What changed in 2024
2024 was year 7 of TCJA's 7-bracket structure, with thresholds inflation-indexed about 5.4% over 2023 - still elevated relative to the pre-pandemic 2-3% norm but well below 2023's anomalous 7.1% adjustment. The standard deduction rose to $14,600 single / $29,200 MFJ, increases of $750 and $1,500 over 2023. The 37% bracket began at $609,350 single / $731,200 MFJ. SECURE 2.0 provisions that activated in 2024 included the new $7,500 catch-up contribution super-tier (with $3,750 for ages 60-63 phasing in for 2025), Roth-only catch-up requirements for high earners, and broader expansion of automatic-enrollment defaults for new 401(k) plans. The Inflation Reduction Act's 15% corporate alternative minimum tax took effect for tax year 2024, applying to corporations with average annual book income exceeding $1 billion. For a single filer with $100,000 taxable income, 2024 federal income tax was approximately $14,260, an effective rate of 14.26% - moderately below 2023's effective rate at the same nominal income.
