How Freelancers Are Taxed

Freelancers are classified as self-employed, which means you work for yourself and file your own tax returns rather than receiving a W-2 from an employer. You report all income on Schedule C (Profit or Loss From Business) and pay self-employment tax on your net profit. Unlike employees, no one withholds taxes from your paychecks, so you are responsible for setting money aside and making quarterly estimated payments to the IRS.

A client that pays you $2,000 or more for services in 2026 must issue you a 1099-NEC (the threshold was $600 for payments made in 2025). Clients below the threshold send nothing, but you still report that income. These forms report gross payments before you subtract any business expenses, so your taxable income is lower after you deduct legitimate business expenses on Schedule C.

Schedule C and Self-Employment Taxation

Schedule C is the form freelancers use to calculate business profit or loss. You list all gross income in Part I, then subtract all allowable business expenses in Part II, and the difference is your net profit. Net profit goes to Schedule SE to calculate your self-employment tax (15.3% on 92.35% of net earnings), and it also flows through Schedule 1 to Form 1040 for regular income tax.

Track and document business expenses as they happen rather than rebuilding them in April. Keep receipts, bank statements and records for at least three years in case of an IRS audit. Self Employment Toolkit (from the same publisher as this site) is a web app with a free expense tracker whose categories map to Schedule C lines, plus mileage, time tracking and invoicing tools.

Common Freelance Deductions

Freelancers can deduct a wide range of legitimate business expenses on Schedule C:

• Home office (simplified method or actual expenses)
• Software subscriptions and tools
• Equipment (computer, camera, instruments, etc.)
• Professional services (accountant, lawyer, web designer)
• Advertising and marketing
• Education and professional development courses
• Business vehicle mileage (standard rate or actual expenses)
• Phone and internet (business-use percentage only)
• Travel and meals (subject to limitations)
• Office supplies and workspace furniture

The general rule is that an expense is deductible if it is ordinary and necessary for your business. Be conservative with gray-area deductions and keep documentation in case you need to explain your reasoning to the IRS.

Quarterly Estimated Tax Payments

If you expect to owe $1,000 or more in federal taxes for the year, the IRS requires you to make quarterly estimated tax payments. These are due on April 15, June 15, September 15, and January 15. You can pay through IRS Direct Pay, the EFTPS system, or your state's payment portal.

A simple approach is to estimate your annual tax using the calculator above, then divide by four and pay that amount each quarter. If your income varies significantly, you can use the annualized installment method (Form 2210, Schedule AI) to adjust payments quarter by quarter. Missing quarterly deadlines can trigger an underpayment penalty even if you pay in full when you file your annual return.

W-2 Income and the Social Security Wage Base

If you have both freelance income and a W-2 job, the Social Security portion (12.4%) of self-employment tax stops once your combined W-2 wages and SE earnings hit the Social Security wage base ($176,100 in 2025; $184,500 in 2026). After that threshold, you only owe the 2.9% Medicare portion on additional SE earnings. The calculator above handles this interaction automatically when you enter both income types.
