Self-Employment Tax in 2026: A Complete Guide for Freelancers, Contractors, and Business Owners

‍

Understanding self-employment tax is essential for freelancers, independent contractors, and small business owners. As the 2026 tax filing season approaches (covering 2025 income), staying informed about current tax rules, rates, deductions, and filing requirements can help you remain compliant while minimizing your tax burden.

‍

This guide explains self-employment tax in 2026, how it’s calculated, who must pay it, and strategies to plan ahead effectively.

‍

‍

What Is Self-Employment Tax?

‍

Self-employment tax is a federal tax that funds Social Security and Medicare for individuals who work for themselves. Unlike traditional employees, who share these taxes with their employer, self-employed individuals are responsible for paying the entire amount themselves.

‍

This tax ensures eligibility for future benefits such as:

• Social Security retirement income

• Disability benefits

• Medicare coverage

‍

‍

Self-Employment Tax Rate for 2026

‍

For the 2026 tax year, the self-employment tax rate remains:

• 12.4% for Social Security

• 2.9% for Medicare

• Total: 15.3%

‍

📅 Only 92.35% of your net self-employment income is subject to this tax. While the rate itself has not changed, income limits and thresholds are adjusted annually for inflation.

‍

‍

Who Is Required to Pay Self-Employment Tax?

‍

You must pay self-employment tax if:

‍

• You earned $400 or more in net profit from self-employment during the year

• You are a:
  • Freelancer
  • Independent contractor
  • Sole proprietor
  • Partner in a partnership
  • Gig economy worker
  • Online seller or consultant

💰Even side income or part-time self-employment may trigger this tax obligation.

‍

How to Calculate Self-Employment Tax in 2026

‍

Step 1: Calculate Net Earnings

‍

Net earnings are determined by subtracting allowable business expenses from your gross business income.

‍

Common deductible expenses include:

• Office supplies and equipment

• Home office expenses

• Internet and phone usage

• Business travel and meals

• Marketing and advertising

• Professional services such as accounting or legal fees

‍

🗂️ Accurate recordkeeping is critical to reducing your taxable income.

‍

‍

Step 2: Apply the Self-Employment Tax Formula

‍

1. Multiply net earnings by 92.35%
2. Multiply the result by 15.3%

‍

Example:

Net earnings: $50,000
Taxable portion: $46,175
Self-employment tax owed: $7,070

‍

🧮 This tax is separate from federal income tax, which is calculated based on your total taxable income.

‍

‍

‍
