Freelancer Tax Deductions: Complete 1099 Write-Off Guide (2025)
How freelancer taxes work
As a freelancer or independent contractor, you are self-employed in the eyes of the IRS. You report your income and expenses on Schedule C (Form 1040), which determines your net profit — the amount subject to both income tax and self-employment (SE) tax.
Unlike W-2 employees, freelancers pay SE tax of 15.3% on net earnings. This covers both the employee and employer portions of Social Security and Medicare. That's why business deductions matter so much: every dollar you deduct reduces income subject to both income tax and SE tax.
The good news: freelancers have access to dozens of legitimate deductions that W-2 employees don't. If you're not tracking your expenses throughout the year, you're almost certainly overpaying.
Top deductions for freelancers
If you work from a dedicated space at home, you can deduct a percentage of rent, utilities, and internet based on square footage. The space must be used exclusively and regularly for business.
The portion of your internet bill used for work is deductible. If you use your home internet 60% for business, 60% is a write-off.
Same rule as internet — deduct the business-use percentage of your monthly phone bill. For most freelancers, this ranges from 50–80%.
Figma, Notion, Slack, Adobe CC, GitHub, Zoom, invoicing software, accounting tools — any software you use for client work or business operations is fully deductible.
Online courses, tutorials, books, and workshops that maintain or improve skills used in your current freelance business are deductible. They must relate to your existing work — not a career change.
Portfolio website hosting, LinkedIn Premium, social media ads, business cards, and any paid promotion for your freelance services.
If you hire other freelancers or subcontractors to help on projects, those payments are deductible as contract labor. You may need to file 1099-NECs for contractors paid $600+.
Freelancers who aren't eligible for an employer-sponsored plan can deduct 100% of health, dental, and vision insurance premiums for themselves and their families.
Quarterly estimated taxes
Freelancers don't have an employer withholding taxes from a paycheck. Instead, you're required to pay estimated taxes four times per year — April 15, June 15, September 15, and January 15 — if you expect to owe $1,000 or more when you file.
Underpaying estimated taxes can trigger an IRS penalty. The more deductions you can accurately identify, the lower your quarterly payments need to be.
