Tax Brackets and Federal Income Tax Rates for 2023 and 2024

Federal income tax in the U.S. is a progressive tax system, meaning the tax rate increases as taxable income increases. The U.S. system is divided into seven tax brackets based on income and filing status.

For example, if you are single and have $11,000 in taxable income in 2023, you owe the government 10%($1,100). The same percentage applies to a married couple filing a joint return if their combined income is $22,000 or less. For heads of household the 10% tax rate applies up to $15,700. Tax rates remain the same, but the allowable incomes are higher due to inflation.

How income tax brackets work

The government uses income tax brackets to determine your tax rate based on your taxable income. Tax brackets are divided into income ranges, each with a set tax rate. As your income increases and you move into a higher tax bracket, only the portion of your income within that bracket is taxed at the higher rate, not your entire income. This system ensures that higher-income individuals pay an increasingly larger percentage of their income in taxes than those with lower incomes.

Income tax rates: types

There are two types of income tax rates: marginal and effective (also known as “average”).

What is a marginal tax rate?

Marginal tax rates are the percentage paid on the last dollar of taxable income earned. In other words, it is the highest tax rate you pay. The marginal tax rate differs from the average or effective tax rate, which is your total tax liability divided by taxable income.

For example, let’s say you are a single filer with a taxable income of $150,000 in 2023. According to the tax brackets and rates for 2023, your total income falls into the 24% tax bracket. Your marginal tax rate is 24%, and you will pay 24 cents in taxes for every dollar of income earned from $95,376 to $150,000. Your average or effective tax rate is lower than your marginal tax rate, because the marginal tax rate only applies to the income within that bracket, not all taxable income.

What is an effective tax rate?

The effective tax rate is the average tax rate paid on all taxable income earned. It considers all tax deductions and credits and better indicates an individual's overall tax burden.

To calculate the effective tax rate, divide the total amount of taxes due by taxable income. Using the example of a single filer with taxable income of $150,000 and $29,400 in taxes due, divide $29,400 by $150,000 to arrive at 0.196 or an effective (average) tax rate of 19.6%.

How to calculate your federal income tax bracket

You need to know your taxable income and filing status to calculate your federal income tax bracket. Taxable income is the amount subject to taxation after all deductions and exemptions have been applied. Your marital status and family situation determine your filing status. There are five types of status: single, married filing separately, married filing jointly, qualifying widow(er), and head of household.

Once you have determined your taxable income and filing status, you can use the tax brackets and rates for the current tax year to calculate your federal income tax bracket. The tax system is divided into seven tax brackets based on the taxpayer’s income and filing status. The tax brackets are adjusted annually to account for inflation.

The following steps can be used to calculate your federal income tax bracket.

1. Determine your taxable income.
2. Determine your filing status.
3. Look up the tax brackets and rates for the current tax year.
4. Identify all the tax brackets into which your taxable income falls.
5. Your income's highest bracket is your tax bracket.
6. Calculate the tax liability for the income within each bracket using the corresponding tax rate.
7. Add up the tax liability for each bracket to get your total federal income tax liability.

Using the example of a single filer with taxable income of $150,000, total tax liability is computed as follows:

How to get into a lower tax bracket

You need to reduce your taxable income to get into a lower tax bracket. Here are some ways to do that.

Maximize your deductions

Deductions are expenses that can be subtracted from your taxable income, reducing the income subject to tax. Some common deductions include charitable donations, state and local taxes, casualty and theft losses, medical expenses, and mortgage interest and points. Make sure you compare the total of your possible itemized deductions with the standard deduction and take the higher of the two.

Contribute to a retirement account

Contributions to certain tax-advantaged retirement accounts, such as a traditional individual retirement account (IRA) or a 401(k) plan, can reduce your taxable income by your contribution amount.

Take advantage of tax credits

Tax credits are even more valuable than deductions because they reduce your tax liability dollar-for-dollar. Some common tax credits include the earned income tax credit, the child tax credit, and the American opportunity tax credit.

Sell losing investments

If you have investments that have lost value, you can sell them to offset capital gains from other investments. This can reduce your taxable income.

Delay income

If you delay income until the following year, you can reduce your taxable income for the current year.

Choose tax-efficient investments

Some investments are more tax efficient than others. For example, most municipal bonds are exempt from federal income tax, making them a good choice for investors in higher tax brackets. It’s important to consult a tax professional to determine the best strategy for your individual situation and ensure that you are not running afoul of tax laws.

TIME Stamp: Tax brackets provide a road map to how much you owe

IRS tax brackets and tax rate tables constitute a road map to how much you owe in federal income taxes for the year. The rates are adjusted for inflation, and your bracket or marginal tax rate is where your last dollar of income falls.

Your total taxes include an increasing percentage of taxable income, including that last bracket. The progressive nature of the American tax system ensures that the larger your income, the higher the percentage of that income you pay in taxes.

Frequently Asked Questions (FAQs)

What is my tax bracket for 2023?

You need to know your taxable income and filing status to determine your federal income tax bracket, the highest bracket in which you have taxable income. Taxable income is the amount subject to taxation after all deductions and exemptions have been applied. Your marital status and family situation determine your filing status.

How many tax brackets are there?

There are seven tax brackets, each with its own tax rate. You pay that tax rate on the amount of your taxable income that falls within the bracket. Thus, if you are a single taxpayer and have a taxable income of $609,351 or higher, putting you in the highest tax bracket, you are not paying that bracket’s rate (37%) on all of your money. Rather, you are paying taxes at the rates of 10%, 12%, 22%, 24%, 32%, 35%, and 37%.
