Taxation is a fundamental aspect of operating a business in the United States. Understanding the various tax obligations is crucial for compliance and financial planning. This article explores the key components of business taxation, including types of taxes, business structures, and common deductions.
Types of Business Taxes

Businesses in the U.S. face various types of taxes at federal, state, and sometimes local levels:
- Corporate Income Tax: Corporations are subject to a federal corporate income tax rate of 21% since the Tax Cuts and Jobs Act (TCJA) of 2017. Many states also levy corporate income taxes, with rates varying significantly across jurisdictions—from 2.5% in North Carolina to 11.5% in New Jersey12.
- Pass-Through Taxes: Entities such as sole proprietorships, partnerships, and S corporations do not pay corporate income tax. Instead, profits are passed through to owners and taxed at their individual income tax rates, which range from 10% to 37%24.
- Self-Employment Tax: Self-employed individuals must pay self-employment taxes, which cover Social Security and Medicare contributions. This tax is approximately 15.3% on net earnings.
- Sales Tax: Businesses that sell goods or services may be required to collect sales tax from customers, which varies by state.
- Payroll Taxes: Employers must withhold payroll taxes from employee wages for Social Security and Medicare, as well as pay their own share of these taxes.
Business Structures and Their Tax Implications
The structure of a business significantly influences its tax obligations:
- C Corporations: Subject to a flat federal tax rate of 21%, C corporations face double taxation—once at the corporate level and again on dividends paid to shareholders34.
- S Corporations: These entities allow profits to be passed through to shareholders without facing corporate income tax, avoiding double taxation2.
- Limited Liability Companies (LLCs): LLCs can choose how they are taxed—either as a corporation or as pass-through entities5. This flexibility can provide significant tax advantages.
- Sole Proprietorships and Partnerships: These are taxed at the owner’s personal income tax rate, making them simpler but potentially subjecting owners to higher individual rates depending on their total income2.
Common Deductions for Businesses
Businesses can reduce their taxable income through various deductions:
- Cost of Goods Sold (COGS): Direct costs attributable to the production of goods sold by a business.
- Operating Expenses: Costs incurred in the normal course of business operations, such as rent, utilities, and salaries.
- Depreciation: Businesses can deduct the cost of tangible assets over their useful life.
- Business Interest Expense: Interest paid on business loans can be deducted from taxable income.
Conclusion
Understanding the basics of taxation is essential for business owners to ensure compliance and optimize their tax liabilities. By knowing the different types of taxes, recognizing how business structure affects taxation, and taking advantage of available deductions, businesses can navigate the complex landscape of taxation more effectively.
