Business tax brackets in 2024-2025 explained

If you own a business or otherwise work in the United States, you must pay federal income taxes. This is a percentage of your taxable income that you pay to the IRS to help cover the cost of government, schooling, and infrastructure across the country.

As is the case for employed taxpayers, small business owners rely on tax brackets determining what percentage of their income they must pay for federal income tax.

Small business tax brackets

Small business taxes are taxes you must pay as a percentage of your small business earnings. In the United States, that depends on your business type. In 2025, tax cuts as part of the Tax Cuts and Jobs Act (TCJA) set a 21% flat-rate tax on corporations. However, most business structures are pass-throughs. These are sole proprietorships, partnerships, or S corporations that report income on the individual tax returns of the business owner and are taxed at individual income tax rates.

As a result, their corporate income tax rates depend on the individual income tax brackets of the business owners. These range from 10% to 37%, depending on how much personal income you generate.

• Corporation (C Corp): 21% Flat Rate
• Sole proprietorships: 10%–37%
• Partnerships: 10%–37%
• Limited liability corporations (LLCs): 10%–37%
• S corporations: 10%–37%

Business tax brackets by state

Although everyone must pay federal income tax, filers in some states may also be required to pay state taxes. For example, filers in states like Alaska, Florida, Indiana, Montana, Nevada, and New Hampshire pay lower state taxes than filers in states like California, Iowa, Louisiana, Maryland, Minnesota, New York, and Vermont. Research your state tax code to determine your state tax rates, if any exist.

Business taxes based on business type

When you file a federal income tax return, your business structure makes a difference. That’s because pass-through businesses are taxed at different rates than corporations. Learn more about each business structure below.

Sole proprietor

If you’re the sole owner of a company that’s not incorporated, you’re a sole proprietor. As such, you’ll pay business taxes based on your personal tax rate.

Partnership

If you’re an owner of a partnership, you will be taxed based on your personal income tax bracket as it relates to your share of business income. All other owners will pay their own share of the partnership’s taxes.

LLC

Limited liability companies are also pass-through corporations for tax purposes. As a result, the LLC business tax rate is equal to the owner’s personal tax rate. If you have partners in your LLC, you’ll pay taxes as a partnership following the guidelines above.

Corporation

C corporations receive special tax treatment as part of the Tax Cuts and Jobs Act (TCJA). Since 2018, corporations have paid a flat 21% corporate tax rate.

S corporation

S corporations are taxed as pass-throughs based on the owner’s personal income tax rate. If you have partners, your company will be taxed as a partnership. However, there are some unique S corporation tax benefits, like savings on self-employment taxes.

Additional business taxes to consider

Federal income taxes aren’t the only tax burdens you’ll face as a business owner. In fact, there are several taxes you’ll need to consider to stay in the good graces of state and federal regulators. Find the details of these taxes below.

Payroll taxes

As a business owner, you contribute FICA taxes alongside your employees to fund Social Security and Medicare benefits. You withhold a portion of employee wages for these taxes while matching their contribution as the employer.

Self-employment taxes

Self-employment or FICA taxes pay for services like Social Security and Medicaid. Salaried employees spend half of this tax, while their employers pay the other half. As a business owner, you’ll be responsible for your entire FICA tax burden and deduct the employer portion of FICA taxes as a business expense.

Capital gains taxes

If your company produces income through investments, you must pay capital gains taxes on that income. Capital gains taxes are lower than federal income taxes, ranging from 0% to 20%, depending on your overall income.

Property taxes

As is the case for individuals, if your company owns real estate or other taxable property, you must pay property taxes to your local tax collector.

Dividend taxes

Many companies pay their owners and other shareholders dividends. Qualified dividend payments are subject to 0%, 15%, or 20% tax rates based on your overall personal income.

Sales taxes

In the U.S., 45 states assess statewide sales taxes, and 38 states require business owners to pay local sales taxes, each with its own list of rates and exceptions. Be sure to look into sales tax requirements in the states where you sell goods.

Excise taxes

Excise taxes are taxes placed on specific goods like alcohol, gasoline, and firearms. If you operate a business that sells these or similar goods, you must pay excise taxes based on sales.

When to file your small business taxes

The deadline to file 2024 personal tax returns is April 15th, 2025. Several types of business returns are due on March 15th, 2025. However, payroll taxes are paid at least quarterly, and other taxes (like sales tax) may require monthly payments.

Foreign business dealings

As a United States-based company operating globally, you’ll be required to pay your federal and local income taxes. However, it’s also important to consider global tax requirements. Be sure you understand the tax burdens associated with each country you either ship goods to or provide services to. If you’re a nonresident alien doing business in the United States, your income will be taxed at a flat 30% rate.

E-commerce business taxes

As an e-commerce business owner, you likely operate across state lines and may operate internationally. If so, it’s important to consider the tax regulations associated with the areas you ship products to or provide services to. For example, if you ship products to Florida, you’ll be required to pay Florida’s sales taxes.

Business tax filing do’s and don’ts

As with any process, you should consider do’s and don’ts as you prepare and file your company’s taxes. Find the details of these below.

Do's

• File on time: If you file your taxes late, you must pay IRS penalties.
• Keep track: Don’t just focus on your taxes at the end of the year. Keep track of your finances and have your records ready at all times.
• Be accurate: Write-offs reduce your tax burden, but inaccurately deducting items can result in significant penalties.
• Reduce your burden: Take advantage of any deductions you and your business qualify for to reduce your tax burden.

Don’ts

• Use round numbers: Never round numbers on tax documents. All information must be accurate to the penny.
• Wait until the end of the year: Accounting is a year-round process, and it’s important to have your records available at all times.
