Income is subject to taxation at multiple levels, including federal, state, and local governments. The federal income tax system follows a progressive structure, meaning tax rates increase as income rises. Marginal tax rates currently range from 10% to 37%, impacting individuals based on their earnings.

The Federal Income Tax: How Are You Taxed?
The federal personal income tax, administered by the Internal Revenue Service (IRS), serves as the primary revenue source for the U.S. federal government. Nearly all working Americans must file an annual tax return with the IRS. Additionally, most individuals pay taxes throughout the year through payroll tax withholdings.
U.S. income taxes are calculated using a progressive tax system, with rates ranging from 10% to 37%. Taxpayers can reduce their overall tax liability by utilizing deductions and credits, which help lower the amount owed.
Federal Income Tax: W-2 Employees
W-2 employees are individuals who receive a W-2 tax form from their employer detailing their annual earnings and the payroll taxes withheld for a specific tax year.
Employers deduct a portion of employees’ earnings to cover various taxes, including federal income tax, Social Security tax, Medicare tax, and applicable state income taxes.
Under the Federal Insurance Contributions Act (FICA), employers and employees share the responsibility of funding Social Security and Medicare programs. The total FICA tax rate is 15.3% of an employee’s wages, with the cost split evenly—7.65% paid by the employer and 7.65% deducted from the employee’s paycheck.
Federal Income Tax: 1099 Employees
Independent contractors, unlike W-2 employees, do not have federal taxes withheld from their pay. Since they are classified as self-employed rather than employees, they are responsible for paying their federal payroll taxes, commonly known as self-employment tax.
Under the Federal Insurance Contributions Act (FICA), both independent contractors (1099 workers) and W-2 employees must pay Social Security and Medicare taxes. However, while W-2 employees split the 15.3% FICA tax rate with their employer, 1099 workers must cover the full amount themselves.
The IRS requires businesses to issue a 1099 form to independent contractors who earn $600 or more in a tax year.
For those looking to optimize their tax strategy, consulting a financial advisor can provide valuable guidance on tax planning and overall financial goals.
Calculating the Federal Income Tax Rate
The United States follows a progressive income tax system, where higher income levels are subject to higher tax rates. These rates, known as “marginal tax rates,” apply only to income within specific ranges rather than an individual’s total earnings. These income ranges are called tax brackets.
Each portion of income is taxed at the rate assigned to its corresponding bracket. The table below outlines the federal income tax brackets for the 2024 tax year, which apply to taxes due in April 2025.
2024 – 2025 Income Tax Brackets
| Taxable Income | Rate |
|---|---|
| $0 – $11,600 | 10% |
| $11,600 – $47,150 | 12% |
| $47,150 – $100,525 | 22% |
| $100,525 – $191,950 | 24% |
| $191,950 – $243,725 | 32% |
| $243,725 – $609,350 | 35% |
| $609,350+ | 37% |
Tax brackets vary based on filing status, which includes categories such as Single, Married Filing Jointly, Married Filing Separately, and Head of Household. Married couples can choose to file jointly or separately, with joint filing often providing tax benefits, though separate filing may be advantageous in specific circumstances.
For example, a single filer earning $50,000 in taxable income falls into the 22% marginal tax bracket. However, this does not mean their entire income is taxed at that rate. Instead, they pay:
- 10% on the first $11,600
- 12% on the next $35,550
- 22% on the remaining $2,850
This progressive system results in a total tax liability of $6,053, leading to an effective tax rate of approximately 12.1%—lower than their top marginal rate.
Tax Withholding Estimator: Calculating Taxable Income Using Exemptions and Deductions
Federal tax rates apply only to taxable income, which differs from gross income—your total earnings before any deductions. Since the U.S. tax system allows certain deductions, taxable income is typically lower than gross income.
To determine taxable income:
- Start with Gross Income – Your total earnings before any adjustments.
- Calculate Adjusted Gross Income (AGI) – Reduce gross income by eligible adjustments.
- Apply Deductions – Subtract either the standard deduction or itemized deductions to arrive at taxable income.
It’s important to note that personal exemptions no longer exist at the federal level. Before 2018, taxpayers could claim a personal exemption to reduce taxable income, but this provision was eliminated under the 2017 tax reform.
2024 – 2025 Federal Standard Deductions
| Filing Status | Standard Deduction Amount |
|---|---|
| Single | $14,600 |
| Married, Filing Jointly | $29,200 |
| Married, Filing Separately | $14,600 |
| Head of Household | $21,900 |
Some taxpayers may choose to itemize deductions instead of taking the standard deduction. Itemizing allows individuals to subtract specific eligible expenses from their taxable income, potentially reducing their tax burden. Standard itemized deductions include:
- State and Local Taxes (SALT) Deduction – Taxpayers can deduct up to $10,000 in combined state and local property taxes plus either state and local income taxes or sales taxes.
- Mortgage Interest Deduction—Interest paid on mortgages for up to two homes is deductible. The limit for homes purchased before Dec. 15, 2017, is $1 million in mortgage debt. For homes purchased after this date, the deduction is capped at $750,000.
- Charitable Contributions – Donations to qualified charities may be deducted.
- Medical Expense Deduction – Medical expenses that exceed 7.5% of Adjusted Gross Income (AGI) can be deducted.
However, most taxpayers do not itemize since the standard deduction often provides more significant tax savings. If the total of your itemized deductions is less than the standard deduction, it’s generally better to take the standard deduction.
How to Calculate Federal Tax Credits
Unlike adjustments and deductions, which reduce taxable income, tax credits directly reduce tax liability—the total amount of tax owed.
For example, if your calculated tax liability is $1,000, and you qualify for a $200 tax credit, your liability is reduced to $800.
Types of Tax Credits
Tax credits are available only in specific situations and fall into two categories:
- Refundable Tax Credits – If the credit exceeds your tax liability, you can receive the remaining amount as a refund.
- Nonrefundable Tax Credits – These can reduce your tax liability to zero, but any excess credit is not refunded.
Common Federal Tax Credits
- Earned Income Tax Credit (EITC) – A refundable credit for low- to moderate-income taxpayers. For 2024, the maximum credit is $7,830 for those with three or more children ($8,046 for 2025).
- Child and Dependent Care Credit – A nonrefundable credit of up to $3,000 for one child or $6,000 for two or more children to offset childcare expenses while working or job hunting.
- Adoption Credit – A nonrefundable credit for qualified adoption-related expenses.
- American Opportunity Tax Credit (AOTC) – A partially refundable credit of up to $2,500 per year for tuition, course materials, and other qualifying expenses during the first four years of higher education.
- Other Credits – Additional credits exist for energy-efficient home improvements, foreign taxes paid, and certain health insurance costs.
By leveraging available tax credits, eligible taxpayers can significantly reduce their overall tax burden.
Calculating Your Tax Refund
Your tax refund depends on the amount of taxes withheld from your paycheck throughout the year, your total tax liability, and any refundable tax credits you qualify for.
How Tax Refunds Work
- If the total amount withheld from your paycheck exceeds your tax liability, you’ll receive a refund for the difference. This is the most common reason taxpayers receive refunds.
- If you paid no taxes during the year but qualify for refundable tax credits, you may still receive a refund equal to the refundable portion of those credits.
Refundable credits, such as the Earned Income Tax Credit (EITC) or the American Opportunity Tax Credit (AOTC), can provide a refund even if you owe no taxes. Understanding tax withholding and available credits can help you maximize your refund or reduce the likelihood of owing taxes at the end of the year.
Paying Your Taxes
If you owe taxes instead of receiving a refund, there are ways to manage the payment and minimize penalties. Filing your tax return on time is crucial, even if you can’t pay the full amount, as late filing penalties are often higher than late payment penalties.
If you’re unable to cover the entire tax bill, paying as much as possible upfront and contacting the IRS can help. The IRS may offer options such as short-term extensions, installment plans, or even temporary collection delays for those facing financial hardship. While interest on unpaid balances will still accrue, some penalties may be waived in some instances.
Another option is paying taxes by credit card, which could earn you rewards. However, IRS-authorized payment processors charge a fee of nearly 2%, so it’s important to weigh the benefits against the costs. More affordable payment methods include IRS Direct Pay, which allows direct transfers from a checking or savings account or sending a check or money order. Most major tax filing services provide instructions for these lower-cost payment options.
State and Local Income Taxes
Many states, along with specific cities and counties, impose their income taxes in addition to the federal income tax. States with an income tax require taxpayers to file a separate state tax return, as each state has its tax laws and regulations.
