Understanding 2025-2026 Federal Tax Brackets
The United States uses a progressive tax system, meaning your income is taxed at different rates as it rises. For the 2025-2026 tax year, there are seven federal income tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%.
It's a common misconception that moving into a higher tax bracket means all your income is taxed at that higher rate. In reality, only the portion of your income that falls within that specific bracket is taxed at that rate. Your effective tax rate is the actual percentage of your total income that goes to the IRS, which is typically lower than your top marginal tax bracket.
2025 Tax Brackets (Single Filers)
- 10% on income between $0 and $11,925
- 12% on income between $11,926 and $48,475
- 22% on income between $48,476 and $103,350
- 24% on income between $103,351 and $197,300
- 32% on income between $197,301 and $250,525
- 35% on income between $250,526 and $626,350
- 37% on income over $626,350
*Note: These are projected brackets for 2025. Actual IRS adjustments may vary slightly due to inflation.
Standard Deduction vs. Itemized Deductions
Taxpayers can choose between taking the Standard Deduction or Itemizing Deductions. The Standard Deduction is a flat amount that reduces your taxable income, no questions asked. Itemizing requires you to list eligible expenses (like mortgage interest, state taxes, and charitable donations) on Schedule A.
2025 Standard Deduction Amounts
- Single & Married Filing Separately:$15,000
- Married Filing Jointly:$30,000
- Head of Household:$22,500
Most Americans (over 85%) choose the Standard Deduction because recent tax laws nearly doubled the amount, making it higher than most people's itemized expenses. Our calculator automatically applies the Standard Deduction based on your filing status unless you specify otherwise.
FICA Taxes: Social Security & Medicare
Beyond federal income tax, your paycheck is also subject to FICA (Federal Insurance Contributions Act) taxes. These fund the Social Security and Medicare programs.
Social Security Tax (6.2%)
You pay 6.2% of your earnings into Social Security, but only up to a certain income limit called the "wage base." For 2025, this limit is projected to be around $176,100. Any income earned above this amount is not taxed for Social Security.
Medicare Tax (1.45% +)
You pay 1.45% of all your earnings into Medicare, with no income limit. High earners (single filers over $200,000 or married couples over $250,000) pay anAdditional Medicare Tax of 0.9% on the excess amount.
Frequently Asked Questions
How do I calculate my effective tax rate?
Your effective tax rate is calculated by dividing your total tax (Federal + FICA) by your gross income. For example, if you earn $100,000 and pay $18,000 in total taxes, your effective tax rate is 18%. This is different from your marginal tax rate, which is the rate applied to the last dollar you earned.
Does this calculator include state taxes?
This specific page focuses on Federal taxes. However, our Take-Home Pay Calculator includes both federal and state tax estimates for all 50 states.
What is the difference between gross pay and net pay?
Gross pay is the total amount you earn before any deductions (the salary offer you accepted).Net pay (or take-home pay) is what actually hits your bank account after federal taxes, state taxes, Social Security, Medicare, and other deductions like health insurance or 401(k) contributions are subtracted.
How can I reduce my taxable income?
Common ways to lower your taxable income include contributing to a 401(k) or 403(b) retirement plan, contributing to a Health Savings Account (HSA), or using a Flexible Spending Account (FSA). These contributions are taken out "pre-tax," meaning they lower the income amount the IRS uses to calculate your taxes.
