Tax Bracket Finder: Marginal Bracket & Effective Rate

Last updated: July 16, 2026

What a Tax Bracket Actually Means

You just got a $15,000 raise that pushes you into the 24% tax bracket. A coworker says, "Watch out—you might take home less now." They're wrong, and this misunderstanding costs people money every year. A federal tax bracket is simply the rate applied to your last chunk of income, not your entire paycheck. To see what a raise actually leaves in your check, run the Salary / Take-Home Calculator.

The U.S. uses a progressive tax system with seven federal brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Each bracket applies only to income within that range. If you're "in the 24% bracket," your first $12,400 is still taxed at 10%, the next $38,000 at 12%, and so on. Only the dollars above $105,700 (single filer, 2026) hit the 24% rate.

This calculator shows your federal and state brackets, how much income falls into each, and what you have left before hitting the next bracket. Use it to plan raises, bonuses, or retirement withdrawals.

How Tax Brackets Work

2026 Federal Brackets, Single Filer (tax year 2026, filed in 2027):

• 10%: $0 – $12,400
• 12%: $12,401 – $50,400
• 22%: $50,401 – $105,700
• 24%: $105,701 – $201,775
• 32%: $201,776 – $256,225
• 35%: $256,226 – $640,600
• 37%: Over $640,600

Married Filing Jointly thresholds are roughly double. For 2026, the 22% bracket starts at $100,801 instead of $50,401. The standard deduction ($16,100 single, $32,200 married filing jointly for 2026) comes off your gross income first, so the brackets apply to what's left. Figures per IRS Rev. Proc. 2025-32.

Marginal Rate vs Effective Rate

Two numbers describe your taxes and people mix them up constantly. Your marginal rate is what the next dollar you earn gets taxed at, the bracket your top dollar sits in. Your effective rate is total tax divided by total income, the average that actually leaves your pocket. In a progressive system the effective rate is always lower, because your early dollars get taxed at 10% and 12% long before anything reaches 22% or 24%.

Which number you want depends on the question. Deciding whether a bonus, a side gig, or a Roth contribution is worth it is a marginal-rate question, because it turns on the next dollar. Budgeting for the year, or checking whether your burden rose since last year, is an effective-rate question. The chart plots both across income for a single filer on 2026 federal brackets. The marginal line steps up at each threshold. The effective line curves up underneath it and never catches up.

Two Taxpayers, Two Calculations

Example 1: Single Filer, $85,000 Income

Rachel earns $85,000 gross. After the $16,100 standard deduction, her taxable income is $68,900. She's "in the 22% bracket," so what does she actually pay?

Rachel's marginal rate is 22%, but she pays 14.3% overall. She has $36,800 of room left in the 22% bracket before any of her income hits 24%.

Example 2: Getting a Raise Across Brackets

Tom has $100,000 of taxable income and gets a $10,000 raise. His coworker says the raise will be "taxed away."

Tom keeps $7,714.00 of the $10,000. Only $4,300 of it is taxed at 24%, the part above $105,700. The first $5,700 is still taxed at 22%. He never "loses money" by earning more, because that isn't how progressive brackets work.

When to Use This (and When Not To)

Use It For:

• Raise/bonus planning: See how much of a raise you'll keep after federal and state tax
• Roth vs. Traditional: If you're in a low bracket now, Roth contributions may beat Traditional
• Year-end decisions: Check headroom before the next bracket to plan Roth conversions or capital gains
• State comparisons: See combined federal + state rates when weighing job offers in different states
• Side income impact: Freelance income is taxed at your marginal rate—know it before pricing projects

Don't Rely on It For:

• Exact tax liability: Credits, itemized deductions, and other factors change the final number
• FICA taxes: Social Security (6.2%) and Medicare (1.45%) are separate from income tax brackets
• Self-employment tax: Add 15.3% SE tax to your marginal rate for freelance income
• AMT exposure: High-income taxpayers may owe Alternative Minimum Tax, which has different brackets

How We Calculate This

We apply the official IRS brackets to your taxable income, layer by layer. If you enter gross income, we subtract the standard deduction for your filing status. State brackets use data from each state's department of revenue (nine states have no income tax at all).

What we include: federal brackets for tax years 2024 through 2026 across all four filing statuses, state income tax brackets for all 50 states plus DC, combined marginal rates, and bracket headroom.

What we don't include: Tax credits (Child Tax Credit, EITC, etc.), itemized deductions beyond the standard deduction option, FICA/self-employment tax, AMT, or state-specific deductions. This is a bracket finder, not a full tax calculator.
