Most small business owners are liable for self-employment tax, which covers social security and medicare taxes. Calculated based on net business income, this tax mirrors the contributions of employees and needs to be factored into the overall tax liability.

Taxable Income and Tax Deductions

Scrutinizing expenses that qualify as deductions, such as operating costs, equipment, and employee wages, significantly impacts the taxable income and, consequently, the tax bill.

Small Business Tax Obligations

Small Business Tax Obligations

Small business owners are subject to a spectrum of taxes, including but not limited to federal income taxes, self-employment taxes, and state income taxes. The tax structure can vary based on the business structure (sole proprietorship, partnership, corporation, etc.) and the nature of operations. Understanding these taxes is pivotal to ascertain the accurate amount due.

Before delving into the methodology of computing business taxes, it’s essential to establish a foundational understanding. While the term business tax is frequently synonymous with federal income tax, it broadly encompasses the diverse taxes applicable to your business operations.

Familiarity with these tax categories holds paramount importance in upholding your business’s compliance with both the IRS and other relevant taxing authorities.

Federal Income Taxation

Federal income taxes likely ring a bell. Similar to filing individual income tax returns annually to the IRS, businesses must also calculate their taxable income and settle federal income taxes. This necessitates periodic quarterly payments throughout the year to meet tax obligations.

States, cities, and counties impose various taxes on small enterprises. Business owners should be mindful of an array of state and local taxes that might be applicable, including:

  • Net profit taxes
  • Gross receipts taxes
  • Franchise taxes

Self-Employment Levies

Entrepreneurs and freelancers, distinct from salaried employees, have the obligation of remitting self-employment tax alongside federal income tax.

This particular levy encompasses Social Security and Medicare taxes, typically withheld by employers from employee paychecks, where both employers and employees share these payments. However, for non-employees, the responsibility lies in covering both the employee and employer portions of Social Security and Medicare tax.

Payroll Taxation

Does your business maintain a staff? If so, it bears the responsibility for payroll taxes.

Payroll taxes serve as contributions toward Social Security, Medicare, and unemployment programs. It’s imperative for businesses to compute and remit these taxes quarterly to the IRS.

Miscellaneous Small Business Taxes

Small-scale enterprises may encounter an assortment of additional taxes, contingent upon individual circumstances. A few noteworthy business tax variations include:

  • Sales and use tax
  • Withholding tax
