How Federal Income Tax Works
The United States uses a progressive tax system, meaning higher income is taxed at higher rates. However, a common misconception is that earning more can result in less take-home pay. In reality, only the income within each bracket is taxed at that bracket's rate. Moving into a higher bracket never causes your overall tax to exceed your raise.
Your taxable income is calculated by subtracting deductions from your gross income. Most taxpayers use the standard deduction, which for 2024 is $14,600 for single filers and $29,200 for married couples filing jointly. If your eligible itemized deductions (mortgage interest, state and local taxes, charitable contributions) exceed the standard deduction, itemizing may lower your tax bill.
This calculator provides an estimate of federal income tax only and does not include Social Security tax (6.2%), Medicare tax (1.45%), state income taxes, or local taxes. For a complete picture of your tax liability, consult a tax professional. Tax brackets and deductions are adjusted annually for inflation by the IRS.
Frequently Asked Questions
What is the difference between marginal and effective tax rate?
Your marginal tax rate is the rate applied to your last dollar of income — the highest bracket you fall into. Your effective tax rate is the average rate you actually pay across all your income. For example, a single filer earning $100,000 has a 22% marginal rate but an effective rate of about 15%, because only income above $47,150 is taxed at 22%.
How do tax brackets work?
Tax brackets use a progressive system where different portions of your income are taxed at different rates. You do not pay your marginal rate on all your income. For example, if you are single and earn $60,000, the first $11,600 is taxed at 10%, the next $35,550 at 12%, and the remaining $12,850 at 22%. This means moving into a higher bracket only affects the income above that threshold.
What is the standard deduction?
The standard deduction is an amount subtracted from your gross income before taxes are calculated, reducing your taxable income. For 2024, the standard deduction is $14,600 for single filers, $29,200 for married filing jointly, $14,600 for married filing separately, and $21,900 for head of household. Most taxpayers take the standard deduction rather than itemizing.
Does this calculator include state taxes?
No, this calculator estimates federal income tax only. State income tax rates and structures vary widely — some states have no income tax (like Texas, Florida, and Washington), while others have rates up to 13.3% (California). Your total tax burden includes federal, state, and potentially local income taxes plus payroll taxes like Social Security and Medicare.
What filing status should I choose?
Single applies to unmarried individuals. Married Filing Jointly is for married couples filing together and usually offers the lowest tax rates. Married Filing Separately is for married couples who want separate returns, though it often results in higher taxes. Head of Household is for unmarried individuals who pay more than half the cost of maintaining a home for a qualifying dependent.
