IRS Schedule C Deductions: What Can Freelancers Write Off in 2025?

Freelancers and self-employed workers in the US can deduct any ordinary and necessary business expense on Schedule C of their Form 1040. The more you track and deduct, the lower your taxable profit — which reduces both your income tax and self-employment tax.

Disclaimer: Tax rules change annually. Verify current deduction limits and rates at irs.gov and consult a qualified CPA before filing.

What Is Schedule C?

Schedule C (Profit or Loss from Business) is the IRS form where sole proprietors, freelancers, and single-member LLCs report business income and deductible expenses. Your net profit (income minus deductions) is what you pay income tax and self-employment tax on. Every dollar you legitimately deduct saves you approximately 25–40 cents in taxes depending on your income bracket.

The Top Schedule C Deductions for Freelancers

1. Mileage and Vehicle Expenses (Line 9)

The IRS standard mileage rate for 2025 is 70 cents per mile for business use (verify at irs.gov for any mid-year updates). Track every business mile: client visits, supply runs, networking events, and post office trips all qualify. Commuting from home to a regular fixed office does not qualify. If you use your home as your principal business location, trips to meet clients may qualify.

You may alternatively deduct actual vehicle expenses — fuel, insurance, maintenance, depreciation — multiplied by your business-use percentage. Choose your method in the first year you use the vehicle for business.

2. Home Office Deduction (Line 30)

If you use part of your home regularly and exclusively for business, you can deduct it using either:

• Simplified method: $5 per square foot, up to 300 sq ft (maximum $1,500/year). No Form 8829 required.
• Regular method (Form 8829): Actual home expenses (rent or mortgage interest, utilities, insurance) × business-use percentage. Usually yields a larger deduction.

3. Health Insurance Premiums

Self-employed individuals not eligible for employer-sponsored health coverage can deduct 100% of health, dental, and vision insurance premiums for themselves and their family. This is claimed on Schedule 1 (not Schedule C) but directly reduces your AGI — one of the most valuable self-employment deductions available.

4. Retirement Contributions

Contributions to a SEP-IRA (up to 25% of net SE income, max $70,000 for 2025) or Solo 401(k) are deductible. Every dollar contributed reduces your taxable income dollar-for-dollar and grows tax-deferred — the single most powerful tax-planning tool for self-employed individuals.

5. Software and Subscriptions (Line 27a)

Any software or subscription used for your business is fully deductible: accounting tools, project management apps, design software, cloud storage, professional memberships, and industry publications. This includes TaxSort Pro — your expense tracking app is itself a deductible business expense.

6. Phone and Internet (Line 25)

Deduct the business-use percentage of your monthly phone plan and home internet. Freelancers who work primarily from home commonly deduct 50–80% of their internet bill. Keep records showing how you calculated the percentage.

7. Office Supplies (Line 18)

Paper, printer ink, postage, pens, and other consumables used for your business are deductible in the year purchased.

8. Professional Development (Line 27a)

Courses, books, certifications, and conferences that maintain or improve skills in your current trade are deductible. Training for a new career is not. The distinction matters — the IRS requires education to relate to your existing business activity.

9. Business Meals (Line 24b)

Business meals with clients, prospects, or partners are 50% deductible. Document the date, attendees, business purpose, and amount for every meal. A general networking lunch qualifies; a personal lunch where you happen to think about work does not.

10. Professional and Legal Fees (Line 17)

Accounting fees, attorney fees for business matters, and bookkeeping costs are fully deductible. Keep all invoices from your CPA and any lawyers engaged for business purposes.

11. Business Insurance (Line 15)

Professional liability (E&O) insurance, general liability, and business property insurance premiums are 100% deductible as ordinary business expenses.

12. Platform Fees and Commissions (Line 10)

If you work through a platform (Upwork, Fiverr, Amazon, Airbnb), fees and commissions the platform deducts from your earnings are deductible business expenses. Your 1099 may show gross earnings before platform fees — deduct those fees on Schedule C to avoid paying tax on money you never received.

13. Qualified Business Income (QBI) Deduction

Under the Tax Cuts and Jobs Act (scheduled to expire after 2025 unless extended by Congress), most freelancers earning below income thresholds ($197,300 single / $394,600 married for 2025) can deduct up to 20% of qualified business income. This is claimed on Form 8995 and directly reduces your taxable income without needing to itemize.

What You Cannot Deduct

• Personal expenses (clothing, groceries, personal entertainment)
• Commuting costs to a regular fixed office location
• Fines and penalties paid to government bodies
• Capital expenses in the year of purchase (depreciate instead, or use Section 179)
• Meals without a documented business purpose

Frequently Asked Questions

Can I deduct my laptop on Schedule C?

Yes. If the laptop is used for business, deduct the business-use percentage. Under Section 179, you may be able to deduct the full cost in the year of purchase rather than depreciating it. If you also use it personally, only the business-use percentage qualifies.

Can I deduct my car payment?

Not directly. You can deduct actual vehicle expenses including the business-use portion of lease payments (if leasing), or use the standard mileage rate. Loan payments on a purchased vehicle are not deductible — but depreciation through MACRS or Section 179 is.

What records does the IRS require?

Keep receipts, invoices, bank statements, and mileage logs for all deductible expenses. The IRS generally requires records for three years from the date you filed (six years if you underreported income by more than 25%). Digital records are accepted. TaxSort stores all scanned receipts in the cloud and exports a complete Schedule C breakdown at tax time.

How does tracking affect my taxes?

Every deductible expense you fail to track is money you overpay to the IRS. A freelancer earning $80,000 who misses $15,000 in legitimate deductions overpays approximately $3,700–$5,000 in federal taxes. The habit of capturing expenses throughout the year — not in April — is the most valuable financial habit a self-employed person can build.
