2025 Tax Brackets: 37% Above $626,350 Single, $751,600 Joint

Updated October 4, 2026. Quick answer: For tax year 2025, the income you report on the return filed in 2026, the federal rates run from 10% to 37%. The 37% rate starts above $626,350 of taxable income for single filers and above $751,600 for married couples filing jointly. The IRS set these thresholds in Revenue Procedure 2024-40, and the standard deduction comes off your income before any bracket applies.

How the brackets work

Each rate applies only to the slice of taxable income inside its bracket. A single filer with $100,000 of taxable income pays 10% on the first $11,925, 12% on the next $36,550 (computed as $48,475 minus $11,925) and 22% on the remaining $51,525 (computed as $100,000 minus $48,475). Using the Revenue Procedure’s own row for the 22% bracket, the tax is $5,578.50 plus 22% of the excess over $48,475, which comes to $16,914. Adding the three slices separately gives $16,914, the same figure. This worked example is computed here and is not an IRS example.

The brackets apply to taxable income, which is what remains after the deduction. For the 2026 deduction amounts see the 2026 standard deduction page, which also lists the 2025 amounts.

2025 long-term capital gains thresholds

The same Revenue Procedure sets the income points where the long-term capital gains rate steps up. The maximum zero rate amount is the top of the 0% rate and the maximum 15% rate amount is the top of the 15% rate. Income above the second figure is taxed at the higher capital gains rate.

Filing statusMaximum 0% rate amountMaximum 15% rate amount
Married filing jointly and surviving spouses$96,700$600,050
Head of household$64,750$566,700
Single and other individuals$48,350$533,400
Married filing separately$48,350$300,000

2025 compared with 2026

Revenue Procedure 2025-32 sets the 2026 thresholds. The 37% rate starts at $640,600 for single filers, $14,250 above the 2025 start (computed as $640,600 minus $626,350), and at $768,700 for joint filers, $17,100 above the 2025 start (computed as $768,700 minus $751,600). The full 2026 table is on the 2026 tax brackets page, and the 2027 brackets page explains the status of the next set.

Filing a 2025 return now

These are the rates for income earned in 2025. If you asked for an extension, the IRS says “This gives you until October 15 to file without penalties.” The same page warns: “Make sure you pay any tax you owe by the April filing date.”

Common mistakes

  • Applying the top rate to all income. Only the slice above the threshold is taxed at 37%.
  • Starting from gross income. The brackets apply to taxable income, after the deduction.
  • Using the 2026 table for 2025 income. The 2026 thresholds are higher.
  • Using the single brackets for married filing separately. They match only until the 37% bracket.
