How It Works
The US federal income tax uses a progressive bracket system. You don't pay your marginal rate on all income — each bracket only applies to income within that range.
The basic rule:
- Taxable income = gross income − deductions (standard or itemized) − pre-tax contributions
- Each tax bracket applies only to the portion of income within that range — not your entire income
- Your effective (average) tax rate is always lower than your marginal (top bracket) rate
This calculator estimates federal income tax only. Your total tax burden also includes state income tax, FICA (Social Security at 6.2% and Medicare at 1.45%), and potentially local taxes. The 2026 brackets shown are projections based on current law and expected inflation adjustments.
Tips & Considerations
- Double-check your filing status before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both marginal tax rate and effective tax rate — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to manage your finances.
- If you're unsure about your pre-tax retirement contributions, start with a conservative estimate and adjust from there.
Frequently Asked Questions
What is the difference between marginal and effective tax rate?
Your marginal tax rate is the rate on your last dollar of income — the highest bracket you fall into. Your effective tax rate is the average rate across all your income (total tax ÷ total income). For example, someone in the 22% bracket might have an effective rate of only 12-15% because lower portions of income are taxed at 10% and 12%.
What are the 2026 federal tax brackets?
The 2026 brackets are estimated at 10%, 12%, 22%, 24%, 32%, 35%, and 37% based on current law with inflation adjustments. The TCJA provisions are set to expire after 2025, which could change rates — check IRS.gov for final 2026 rates when published.
What is the standard deduction for 2026?
The estimated 2026 standard deduction is approximately $15,700 for single filers, $31,400 for married filing jointly, and $23,500 for head of household. These amounts are adjusted annually for inflation. If your itemized deductions exceed the standard deduction, itemizing saves you more.
How can I lower my tax bracket?
Common strategies include maximizing pre-tax retirement contributions (401k up to $23,500, Traditional IRA up to $7,000), contributing to an HSA ($4,300 single / $8,550 family), claiming all eligible deductions, and timing income or deductions between tax years.
Does moving to a higher tax bracket mean all my income is taxed more?
No — this is a common misconception. Only the income within each bracket is taxed at that bracket's rate. If you earn $1 over the 22% bracket threshold, only that $1 is taxed at 22%. All income below the threshold is still taxed at the lower rates.
Are state taxes included in this calculator?
No, this calculator covers federal income tax only. State income tax rates vary from 0% (Texas, Florida, etc.) to over 13% (California). Your total tax burden includes federal, state, FICA (7.65%), and potentially local taxes. Use this as a starting point and add your state rate separately.
