These are the tax brackets that apply to money you earn during 2026 — the return you'll file in early 2027, not the one due this April. The IRS locked in these numbers on October 9, 2025, adjusting the prior year's brackets for inflation under Revenue Procedure 2025-32. * For single filers, the seven rates break down like this: 10% up to $12,400, 12% up to $50,400, 22% up to $105,700, 24% up to $201,775, 32% up to $256,225, 35% up to $640,600, and 37% on anything above that. * Married couples filing jointly get roughly double the room at every level: 10% up to $24,800, 12% up to $100,800, 22% up to $211,400, 24% up to $403,550, 32% up to $512,450, 35% up to $768,700, and 37% above that. * Heads of household land in between: 10% up to $17,700, 12% up to $67,450, 22% up to $105,700, 24% up to $201,775, 32% up to $256,200, and 35% up to $640,600 before hitting the top 37% rate. * The standard deduction also rose for 2026: $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for heads of household. Remember, brackets are marginal — you don't pay 37% on your whole income, only the slice that falls in that top bracket.
