Have you ever wondered how the government calculates your yearly federal income tax bill? Understanding how federal income taxes work can help you make informed financial decisions about saving, investing, and retirement planning. This article explains the basic components of calculating federal income taxes, including the tax brackets, taxable income, deductions, and credits.
Taxpayers must determine their taxable income by subtracting applicable deductions and exemptions from their gross income. Deductions and exemptions reduce the amount of income subject to tax, resulting in a lower taxable income. Some common deductions include the standard deduction, personal exemptions, state and local taxes paid, mortgage interest, and contributions to retirement accounts.
Once you have your taxable income, the next step is to determine your tax bracket, which determines the tax rate applied to your income. The higher your taxable income, the higher your tax bracket will be. The tax brackets for 2023 are as follows for Single Filers:
how is federal income tax calculated
Here are eight important points about how federal income tax is calculated:
- Calculate gross income
- Subtract deductions
- Determine taxable income
- Find tax bracket
- Apply tax rate
- Add additional taxes
- Subtract tax credits
- Calculate tax liability
These steps ensure that taxpayers pay the correct amount of taxes based on their income and circumstances.
Calculate gross income
Calculating gross income is the first step in determining your federal income tax liability. Gross income includes all income you receive from various sources, such as wages, salaries, tips, bonuses, self-employment income, dividends, interest, and capital gains.
To calculate your gross income, start by adding up all your earnings from employment, including wages, salaries, bonuses, and tips. If you're self-employed, include your net income from your business or profession. Next, add any income from investments, such as dividends, interest, and capital gains. Be sure to include any taxable income from rental properties or other sources.
Once you have totaled all your income from various sources, you'll have your gross income. This amount is used to determine your taxable income, which is the amount of income subject to federal income tax.
Here are some examples of income that is included in gross income:
- Wages, salaries, tips, and bonuses
- Self-employment income
- Dividends
- Interest
- Capital gains
- Rental income
- Alimony
- Unemployment benefits
- Social Security benefits (in some cases)
Note that some types of income are not included in gross income, such as gifts, inheritances, and certain types of welfare benefits.
Once you have calculated your gross income, you can move on to the next step of determining your taxable income. This involves subtracting certain deductions and exemptions from your gross income.
Subtract deductions
After calculating your gross income, you can reduce your taxable income by subtracting certain deductions. Deductions are expenses or losses that you can subtract from your gross income to arrive at your taxable income. There are two main types of deductions: above-the-line deductions and below-the-line deductions.
- Above-the-line deductions
These deductions are taken directly from your gross income before you calculate your adjusted gross income (AGI). Common above-the-line deductions include:
- Standard deduction
- Student loan interest
- IRA contributions
- Health savings account (HSA) contributions
- Moving expenses (in certain cases)
- Below-the-line deductions
These deductions are taken from your AGI to calculate your taxable income. Common below-the-line deductions include:
- Mortgage interest
- State and local income taxes
- Property taxes
- Medical and dental expenses (exceeding 7.5% of AGI)
- Charitable contributions
- Itemized deductions
You can choose to itemize your deductions or take the standard deduction, whichever is more beneficial to you. Itemizing deductions means listing all of your eligible deductions on your tax return. The standard deduction is a fixed dollar amount that is automatically deducted from your gross income.
- Standard deduction
If you do not itemize your deductions, you can take the standard deduction. The standard deduction amounts for 2023 are:
- $13,850 for single filers
- $27,700 for married couples filing jointly
- $19,400 for married couples filing separately
By subtracting deductions from your gross income, you can reduce your taxable income and potentially lower your federal income tax liability.
Determine taxable income
Once you have calculated your gross income and subtracted any allowable deductions, you will arrive at your taxable income. Taxable income is the amount of income that is subject to federal income tax. It is calculated by subtracting the standard deduction or itemized deductions, and personal exemptions from your AGI.
The standard deduction is a fixed dollar amount that is automatically deducted from your AGI. The standard deduction amounts for 2023 are:
- $13,850 for single filers
- $27,700 for married couples filing jointly
- $19,400 for married couples filing separately
If you choose to itemize your deductions, you can deduct certain expenses from your AGI, such as mortgage interest, state and local taxes, charitable contributions, and medical expenses. The total amount of your itemized deductions cannot exceed your AGI.
Personal exemptions are a specific dollar amount that is deducted from your AGI for each taxpayer and dependent. The personal exemption amount for 2023 is $4,300.
Once you have subtracted the standard deduction or itemized deductions, and personal exemptions from your AGI, you will arrive at your taxable income.
Your taxable income is used to determine your tax bracket and calculate your federal income tax liability. The higher your taxable income, the higher your tax bracket will be, and the more taxes you will owe.
Find tax bracket
Once you know your taxable income, you can determine your tax bracket. Tax brackets are ranges of taxable income that are subject to different tax rates. The higher your taxable income, the higher your tax bracket will be, and the more taxes you will owe.

- 35% bracket: $282,351 to $578,700
- 37% bracket: $578,701 and up
To find your tax bracket, simply compare your taxable income to the ranges listed in the tax brackets. Once you know your tax bracket, you can apply the corresponding tax rate to your taxable income to calculate your federal income tax liability.
Apply tax rate
Once you know your tax bracket, you can apply the corresponding tax rate to your taxable income to calculate your federal income tax liability. The tax rates for 2023 are as follows:
- 10% tax rate: Applies to taxable income in the 10% tax bracket.
- 12% tax rate: Applies to taxable income in the 12% tax bracket.
- 22% tax rate: Applies to taxable income in the 22% tax bracket.
- 24% tax rate: Applies to taxable income in the 24% tax bracket.
- 32% tax rate: Applies to taxable income in the 32% tax bracket.
- 35% tax rate: Applies to taxable income in the 35% tax bracket.
- 37% tax rate: Applies to taxable income in the 37% tax bracket.
To calculate your federal income tax liability, simply multiply your taxable income by the corresponding tax rate. For example, if you are single and your taxable income is $50,000, you would multiply $50,000 by the 22% tax rate to arrive at a federal income tax liability of $11,000.
Add additional taxes
In addition to the regular income tax calculated using the tax brackets, there are a few additional taxes that may apply to your situation. These additional taxes include:
- Medicare tax: This is a 1.45% tax that is applied to all earned income, including wages, salaries, self-employment income, and tips. Medicare tax is also applied to net investment income for high-income taxpayers.
- Social Security tax: This is a 6.2% tax that is applied to all earned income, up to a certain limit. The Social Security tax rate is split evenly between the employee and the employer.
- Self-employment tax: This is a combination of the Social Security tax and the Medicare tax that is paid by self-employed individuals. The self-employment tax rate is 15.3% (12.4% for Social Security and 2.9% for Medicare).
- Alternative minimum tax (AMT): This is a separate tax system that is designed to ensure that high-income taxpayers pay a minimum amount of taxes. The AMT is calculated using a different set of rules than the regular income tax, and it may apply to taxpayers who have a lot of deductions and credits.
If you are subject to any of these additional taxes, you will need to add them to your regular income tax liability to calculate your total federal income tax liability.
Subtract tax credits
Once you have calculated your total income tax liability, you can subtract any tax credits that you are eligible for. Tax credits are dollar-for-dollar reductions in your tax liability. This means that they directly reduce the amount of taxes that you owe.
There are many different types of tax credits available, including:
- Earned income tax credit (EITC): This is a credit for low- and moderate-income working individuals and families. The amount of the EITC depends on your income, filing status, and number of qualifying children.
- Child tax credit (CTC): This is a credit for each qualifying child under the age of 17. The amount of the CTC is $2,000 per child for 2023.
- Dependent care credit: This is a credit for expenses paid for the care of a qualifying child or other dependent. The amount of the dependent care credit is limited to a percentage of your earned income.
- Education credits: There are two main education credits: the American opportunity tax credit and the lifetime learning credit. These credits are available for qualified education expenses paid for the first four years of post-secondary education.
- Retirement savings contributions credit: This is a credit for contributions made to a qualified retirement plan, such as a 401(k) or IRA. The amount of the credit is limited to a percentage of your earned income.
To claim a tax credit, you must meet the eligibility requirements and complete the appropriate tax form. Tax credits are claimed on your federal income tax return.
By subtracting tax credits from your total income tax liability, you can reduce the amount of taxes that you owe. Tax credits can be a valuable way to save money on your taxes.
Calculate tax liability
Once you have calculated your taxable income, applied the appropriate tax rate, and added any additional taxes, you can calculate your federal income tax liability. Your tax liability is the total amount of taxes that you owe to the government.
- Step 1: Calculate your regular income tax liability.
To do this, multiply your taxable income by the tax rate that applies to your tax bracket. For example, if you are single and your taxable income is $50,000, you would multiply $50,000 by the 22% tax rate to arrive at a regular income tax liability of $11,000.
- Step 2: Add any additional taxes.
This includes Medicare tax, Social Security tax, or self-employment tax, if applicable. For example, if you are self-employed and your net income is $50,000, you would add $7,650 in self-employment tax to your regular income tax liability.
- Step 3: Subtract any tax credits.
This includes credits such as the earned income tax credit, child tax credit, and education credits. For example, if you are eligible for the earned income tax credit and have two qualifying children, you could subtract $6,935 from your total income tax liability.
- Step 4: Calculate your total income tax liability.
To do this, simply add up your regular income tax liability, any additional taxes, and subtract any tax credits. For example, if your regular income tax liability is $11,000, you have $7,650 in self-employment tax, and you have $6,935 in tax credits, your total income tax liability would be $11,715.
Once you have calculated your total income tax liability, you can make estimated tax payments throughout the year to avoid owing a large amount of taxes when you file your tax return.
