Here’s what HIVE AI had to say about “How have income tax marginal rates changed for 2025 income?”:
2025 marginal rates
For 2025 income, the federal individual marginal tax rates themselves did not change in percentage terms: they remain 10%, 12%, 22%, 24%, 32%, 35%, and 37%. What changed for 2025 was the income thresholds for each bracket, due to inflation adjustments.
For example, for single filers in 2025, the 10% bracket goes up to $11,925, the 12% bracket runs from $11,926 to $48,475, the 22% bracket runs from $48,476 to $103,350, and the top 37% bracket starts above $626,350. For married filing jointly, the 37% bracket starts above $751,600.
The later One, Big, Beautiful Bill Act did not change the 2025 marginal rate percentages for 2025 income. Its rate provision applies to taxable years beginning after December 31, 2025, essentially making the reduced-rate structure permanent going forward rather than changing the 2025 percentages.
Bottom line
For 2025 income, the marginal rates did not change; only the bracket cutoffs moved upward. If you want, I can list the full 2025 brackets for your filing status.
