A higher standard deduction lowers taxable income before brackets apply. The single deduction moved $750 (up from 2023 to 2024); MFJ moved $1,500. Large jumps usually mean a law change (TCJA) or a high-inflation COLA year.
Both years use the tcja schedule, so most differences are inflation-adjusted thresholds—not new rate percentages.
The sample tax table holds taxable income fixed so you can isolate bracket/threshold changes. Real paychecks also change with deductions, FICA wage bases, and credits—so treat the dollar differences as directional, not a full return comparison.
Use it to research historical law, explain a COLA, or brief a before/after TCJA story. For tax years 2020–2026, open the matching US paycheck calculator (for example /calculator/us/2020 or current /calculator/us) to run a full estimate with that year’s brackets.
