Types of Small Business Taxes

There are several types of small business taxes you may be required to pay. Which taxes you are liable for will primarily depend on what kind of business you own and what state you operate in. Here’s a quick breakdown.

Income tax

All businesses except for partnerships are required to pay income tax. Federal income tax is a pay-as-you-go system. For employees, this typically means a portion of each paycheck is withheld to go towards this income tax. If you don’t have tax withholding (e.g., you’re self-employed), you may be required to pay quarterly estimated taxes on your income.

Pro Tip: Most states require corporate or business income taxes, but each state has different rules. Be sure to look into your own state and local tax laws to ensure you meet your tax obligations.

State taxes can generally be classified into three categories:

Initial formation fees.
Taxes on business income.
Sales and use tax.

The IRS website has a list of links to state government pages with info on individual state tax requirements for businesses.

Estimated tax

Income tax must be paid as it is earned over the year—either through tax withholding or through estimated payments. As a business owner, you will likely need to pay estimated taxes on your self-employment income, unless you are a corporation or S corporation.

Estimated taxes are paid quarterly and are estimated based on your expected adjusted gross income (AGI)—most people use the prior tax year’s income to determine their estimated payments for the following year.

Quarterly estimated tax payments for 2024 are due:

April 15
June 17
September 16
January 15, 2025

Be sure to keep up on your estimated payments as late payments or underpayments can result in a costly penalty.

Employment tax

If your small business has employees, you will be obligated to pay certain employment taxes.

Employment taxes include the following:

Social security and Medicare taxes
Federal income tax withholding
Federal unemployment (FUTA) tax

At the end of the year, you will fill out and file Form W-2 to report employee wages and other compensation in your business. Use Form W-3, Transmittal of Wage and Tax Statements to transmit Forms W-2 to the Social Security Administration.

You must also share a copy of the W-2 by January 31 with your employee(s) for their own tax filing records.

Self-employment tax

If you work for yourself, you’ll be responsible for paying self-employment taxes. Self-employment taxes (also known as FICA taxe s) cover both the business and employee payroll tax obligations for Social Security and Medicare taxes for a total of 15.3% of your gross wages or income.

Pro Tip: Use the self-employment tax deduction to deduct the employer-equivalent portion of your self-employment tax when calculating your AGI.

Excise tax

Excise taxes are taxes levied on specific goods, activities, or services. Businesses that are required to pay excise taxes can include importers, manufacturers, and retailers. Federal excise taxes are usually collected on fuel-related purchases, airline tickets, tobacco sales, and other goods and services.
