Understanding US Federal Income Tax Brackets for 2026
The United States uses a progressive tax system, meaning your income is taxed at increasing rates as it moves through different brackets. For 2026, the IRS has adjusted brackets for inflation. A single filer pays 10% on the first $11,925 of taxable income, 12% on income from $11,926 to $48,475, and so on up to 37% on income above $626,350. Married couples filing jointly get wider brackets — the 10% bracket extends to $23,850, and the top 37% rate does not kick in until $751,601.
Your marginal tax rate is the rate applied to your last dollar of income. Your effective tax rate is the average rate you actually pay across all brackets. These two numbers are almost always different. Someone with $100,000 in taxable income (single) has a 22% marginal rate but pays an effective rate of roughly 17%. Understanding this distinction helps you make smarter decisions about retirement contributions, deductions, and withholding.
Standard vs Itemized Deductions in 2026
Before your income is taxed, you subtract either the standard deduction or your itemized deductions — whichever is larger. The 2026 standard deduction is $15,700 for single filers, $31,400 for married filing jointly, and $23,500 for head of household. Most taxpayers take the standard deduction because it exceeds their total itemizable expenses.
Itemized deductions include state and local taxes (SALT, capped at $10,000), mortgage interest, charitable contributions, and medical expenses exceeding 7.5% of adjusted gross income. If your total itemized deductions are higher than the standard amount, itemizing reduces your taxable income further and lowers your federal tax bill.
Example: Single filer earning $85,000
- Gross income: $85,000
- Standard deduction: $15,700
- Taxable income: $69,300
- Federal tax: $10,490 (effective rate ~12.3%)
- Marginal bracket: 22%
Using This as a 2026 Tax Refund Estimator
A true refund estimate depends on withholding, credits, and total payments already sent to the IRS. This calculator focuses on the tax-liability side first. Once you know your estimated 2026 federal tax, subtract that from your expected withholding and refundable credits to get a practical refund or amount-due estimate. That makes it useful early in the year when you want a quick planning number before full tax software is necessary.

State Income Tax Overview
Nine US states have no state income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Residents of these states keep more of their paycheck because they only pay federal income tax (plus FICA). States with the highest income tax rates include California (up to 13.3%), New York (up to 10.9%), and New Jersey (up to 10.75%). This calculator estimates federal tax only — for a complete picture, add your state income tax rate to the effective federal rate shown in your results.
Tips to Lower Your Federal Income Tax
Contributing to a traditional 401(k) or IRA reduces your taxable income. The 2026 401(k) limit is $24,500 ($32,500 with catch-up for age 50+). HSA contributions are also pre-tax — $4,400 for individuals and $8,750 for families in 2026. Maximizing these accounts can drop you into a lower tax bracket and save thousands.
Dependents also reduce your tax liability through credits. The Child Tax Credit remains up to $2,000 per qualifying child under 17 for most filers. Timing large deductions, bunching charitable contributions into a single year, and harvesting investment losses are additional strategies that can meaningfully reduce what you owe the IRS.

The 2026 standard deduction is $15,700 for single filers and married filing separately, $31,400 for married filing jointly, and $23,500 for head of household. These amounts are adjusted annually for inflation.
What is the difference between marginal and effective tax rate?
Your marginal tax rate is the rate on your last dollar of income — it determines your tax bracket. Your effective tax rate is the total tax divided by total income, representing the average rate you actually pay. The effective rate is almost always lower than the marginal rate because of progressive brackets.
Should I take the standard deduction or itemize?
Take whichever is higher. If your total itemizable expenses (SALT up to $10,000, mortgage interest, charitable donations, medical expenses above 7.5% of AGI) exceed the standard deduction, itemizing saves you more. Most taxpayers benefit from the standard deduction.
Does this calculator include state income tax?
No. This calculator estimates federal income tax only. State income tax varies by state — some states like Texas, Florida, and Nevada have no state income tax, while others like California and New York have rates above 10%.
