Income Tax Brackets

The U.S. federal income tax uses seven progressive brackets with rates from 10% to 37%. Each bracket rate only applies to the income within that range — not to your entire income.

Why It Matters

Understanding how brackets work is essential for comparing job offers, estimating tax liability, and avoiding the common misconception that earning more can "push all your income" into a higher bracket. Your effective tax rate (the blended average) is always lower than your marginal rate (the rate on your last dollar).

How It Works

Think of progressive brackets like filling buckets. Your first dollars fill the 10% bucket. Once that bucket is full ($12,400 for single filers in 2026), the next dollars spill into the 12% bucket, and so on through all seven rates. Each rate only applies to the income within that bracket — not to your entire income. This is why your effective tax rate is always lower than your marginal (highest) bracket rate.

Frequently Asked Questions

Do I pay my highest tax rate on all my income?

No. The U.S. uses a progressive tax system where each bracket rate only applies to the income within that bracket range. Moving into a higher bracket only affects the dollars above the threshold, not your entire income.

This is the most common tax misconception. If you earn $60,000 as a single filer in 2026, you pay 10% on the first $12,400, 12% on income from $12,401 to $50,400, and 22% only on income from $50,401 to $60,000. Your effective rate works out to about 14%, much lower than your 22% marginal rate. Moving into a higher bracket never makes your overall tax go up by more than the extra income earned.

How are the 2026 tax brackets different from 2025?

The 2026 brackets use the same seven rates (10% through 37%) as 2025, but income thresholds increased roughly 2.7% for inflation. The bottom two brackets received a larger 4% adjustment under the OBBBA. Standard deductions also increased: $16,100 single (up from $15,750), $32,200 married filing jointly (up from $31,500).

Tax rates were made permanent by the One Big Beautiful Bill Act (OBBBA) in July 2025, so the seven rates (10%, 12%, 22%, 24%, 32%, 35%, 37%) remain unchanged. What changed for 2026 are the income thresholds, adjusted for inflation per IRS Revenue Procedure 2025-32. The OBBBA provided a larger 4% inflation adjustment for the bottom two brackets (10% and 12%) compared to ~2.3% for higher brackets. For example, the 12% bracket for single filers now ends at $50,400 (up from $48,475 in 2025). The standard deduction rose to $16,100 for single filers and $32,200 for joint filers.

What is taxable income and how do I calculate it?

Taxable income is your gross income minus deductions. Most filers subtract the standard deduction: $16,100 for single, $32,200 for married filing jointly, or $24,150 for head of household in 2026.

The formula is: Taxable Income = Gross Income − Deductions. For example, a single filer earning $90,000 who takes the standard deduction: $90,000 − $16,100 = $73,900 taxable income. You can use either the standard deduction or itemize deductions (mortgage interest, state/local taxes up to $10,000, charitable contributions), whichever is larger. Most taxpayers benefit from the standard deduction. The calculator on this page lets you enter gross income and automatically applies the standard deduction.

What is the difference between marginal and effective tax rate?

Your marginal tax rate is the rate on your last dollar of income. Your effective tax rate is the average rate across all your income (total tax ÷ total income). Because of progressive brackets, your effective rate is always lower than your marginal rate.

For example, a single filer earning $75,000 in 2026 has a marginal rate of 22% (the bracket their last dollar falls in) but an effective rate of only about 14.9% (total tax ÷ $75,000). The difference exists because only a portion of income is taxed at the highest rate. Your effective rate is always lower than your marginal rate in a progressive tax system. Understanding this distinction helps when comparing job offers or evaluating the impact of a raise.
