The Freelancer Tax Deduction Checklist: 25 Write-Offs to Know

Every legitimate deduction reduces the income your self-employment tax and federal income tax are calculated on — which means missed deductions aren't just a paperwork oversight, they're money handed over unnecessarily. The test the IRS applies to any expense is simple: it must be ordinary (common in your line of work) and necessary (helpful and appropriate for your business).

Below are 25 deductions organized into six categories most freelancers touch. Keep documentation — a bank or card statement plus a short note on business purpose is generally enough.

Home office & workspace

1. Home office deduction — a portion of rent/mortgage interest, utilities, and insurance based on the percentage of your home used regularly and exclusively for business (simplified method: $5/sq ft up to 300 sq ft).
2. Office furniture and equipment — desks, chairs, monitors, and similar items used for work.
3. Renters or homeowners insurance (business-use portion) — the share attributable to your home office space.
4. Utilities (business-use portion) — electricity, internet, and heating/cooling proportional to office square footage.

Software & tools

5. Software subscriptions — design, accounting, project management, and industry-specific tools.
6. Website hosting and domain fees — costs of maintaining a professional or portfolio site.
7. Computer and equipment depreciation — laptops, cameras, or other equipment can often be deducted in the year purchased under Section 179, up to certain limits.
8. Cloud storage and backup services used for business files.

Professional services & education

9. Accounting and bookkeeping fees — a CPA or bookkeeper's fee is itself deductible.
10. Legal fees related to contracts, business formation, or collections.
11. Professional association dues and industry memberships.
12. Continuing education — courses, certifications, and conferences that maintain or improve skills used in your current work.
13. Business books and subscriptions relevant to your field.

Marketing & admin

14. Advertising and marketing costs — paid ads, printed materials, and portfolio platforms.
15. Business cards and branding — logo design, print materials.
16. Bank and payment processing fees — business account fees, Stripe/PayPal transaction fees.
17. Contract labor — payments to subcontractors or freelancers you hire (issue a 1099-NEC once payments cross the current reporting threshold for the year — this threshold changed recently, so verify the current figure at IRS.gov).

Travel & vehicle

18. Business mileage — trips to client meetings, the post office for business mail, or supply runs, tracked contemporaneously.
19. Travel expenses — flights, hotels, and 50% of meals for business trips away from your regular workplace.
20. Parking and tolls for business-related travel.

Benefits & taxes

21. Self-employed health insurance premiums — often 100% deductible above the line; see our Health Insurance guide.
22. Half of self-employment tax — automatically calculated on Schedule SE as an above-the-line deduction.
23. Retirement plan contributions — SEP IRA or Solo 401(k) contributions; see our Retirement guide.
24. HSA contributions if enrolled in a qualifying high-deductible health plan.
25. State and local business taxes — franchise fees or business licenses paid to your state or city.

How to actually track these through the year

The deductions above are only useful if you can substantiate them. Most freelancers do this one of two ways: a dedicated business bank account and card where nearly every transaction is presumptively deductible (see our Business Banking guide), or bookkeeping software that lets you tag transactions by category as they happen (see our Bookkeeping Basics guide). Waiting until tax season to reconstruct a year of expenses from memory is the single most common way freelancers under-claim.
