Deductible Business Expenses for US Freelancers: The 2026 Cheat Sheet
"What can I write off?" is the first and last question most freelancers ask about taxes. The answer that's accurate but useless: ordinary and necessary business expenses. The answer that's actually useful is a specific list, with dollar ceilings, gotchas, and the three common mistakes that the IRS flags.
This post is that list. It covers Schedule C deductions for US freelancers in 2026, with the categories ordered by how much they typically save the average sole proprietor earning $40k–$150k in net profit.
The IRS test (in plain English)
IRS Publication 535 defines a deductible business expense as one that is ordinary (common in your trade) and necessary (helpful and appropriate). That's it. The test is deliberately soft; courts have interpreted it generously for real business use and strictly against obvious personal dressed up as business.
You don't have to prove the expense was essential — only that it was reasonable for your business. But the moment personal and business use mix, you need documentation.
The high-leverage categories (ranked by typical savings)
1. Home office (potential $1,500–$8,000 deduction)
For freelancers who work from home regularly and exclusively in a dedicated space. Two methods:
- Simplified: $5 per business sq ft, max 300 sq ft → $1,500 cap. No documentation of utilities required.
- Actual: Calculate business-use %(sq ft of office ÷ total home sq ft). Deduct that % of rent/mortgage interest, utilities, renter's insurance, and depreciation (if owner). Requires keeping utility bills and a floor-plan sketch.
Actual method usually wins above ~$2,500 of deduction. Simplified wins for smaller offices or lazy bookkeeping. Both require "regular and exclusive" use — the space can't also be a guest bedroom or kids' play area. Photos of the space taken annually are the defense.
2. Mileage (58.5¢/mile in 2024, typically $800–$4,000)
Two methods:
- Standard mileage: 58.5¢ per business mile (adjusted annually). Simplest; covers gas, insurance, repairs, depreciation in one rate.
- Actual expenses: Business-use % × (gas + insurance + repairs + depreciation). Requires tracking all receipts and business-use %.
Standard mileage wins 95% of the time unless you drive a luxury vehicle with high depreciation. The catch: the mileage log is mandatory. Date, miles, starting/ending odometer, business purpose. An app like MileIQ or Hustlay's mileage tab records this automatically.
3. Software + subscriptions ($500–$3,000)
Fully deductible when used for the business:
- Productivity: Notion, Figma, Adobe, Slack, Microsoft 365
- Hosting + domains: AWS, Vercel, Cloudflare, Namecheap
- Communication: Zoom, Loom, Calendly, Superhuman
- Dev tools: GitHub, Cursor, JetBrains, 1Password Business
- Design: Creative Cloud, Photoshop, Sketch
- Industry-specific: QuickBooks, Hustlay, MailerLite, Buffer
Mixed-use tools (Netflix, Spotify, Disney+) are not deductible unless you can show ordinary and necessary business use — almost never.
4. Professional services ($500–$5,000)
- Accountant / bookkeeper
- Business attorney (contracts, IP, LLC filing)
- Tax preparation fees for the business portion
- Business coaching / consulting
- Web design, branding, logo design services
Personal tax prep is not deductible; the portion attributable to Schedule C prep is. Most accountants break this out on the invoice.
5. Health insurance (potentially the biggest)
Self-employed health insurance is deductible above the line (on Schedule 1, line 17) if:
- You're not eligible for employer-sponsored coverage (your own or a spouse's)
- You had net profit on Schedule C
- The policy is established under your business name (or your name, if sole prop)
At $800/month marketplace premium, the deduction is $9,600/year. At a 30% combined rate, that's $2,880 in tax savings. Often the biggest single deduction a freelancer has.
6. Retirement contributions ($6,500–$69,000)
Three self-employed retirement plans, in order of capacity:
| Plan | 2024 limit | Best for |
|---|---|---|
| Traditional IRA | $7,000 ($8,000 if 50+) | Anyone with earned income |
| SEP-IRA | 25% of SE income, up to $69,000 | Max contribution with low admin |
| Solo 401(k) | $23,000 employee + 25% employer = up to $69,000 | Max flexibility, allows Roth |
Contributions reduce both federal income tax AND SE tax base. A $20,000 SEP contribution at 22% federal + 15.3% SE = $7,460 in tax savings. This is the single highest-leverage move for high-income freelancers.
The medium-leverage categories
7. Meals (50% deductible)
Meals are 50% deductible when:
- Client / prospect meals with a business purpose
- Meals during business travel (out of your tax home overnight)
- Meals at business conferences or training events
Not deductible: solo meals at home, meals with family unless they're business partners discussing business, grocery runs. Required: receipt + business purpose + who was present.
8. Travel (100% deductible for work trips)
- Flights / trains
- Hotels
- Rideshare + parking
- Conference fees
- 50% of meals during the trip
"Primary purpose" test: if the trip is primarily business, all transportation is deductible. Mixing a vacation day in is fine; tacking a 5-day vacation onto a 1-day conference means allocating transportation costs.
9. Equipment (Section 179 or depreciation)
Laptops, monitors, cameras, office furniture. Two paths:
- Section 179 immediate expense: up to $1.16M in 2024 (unlikely to be a limit for freelancers), deduct full cost in year of purchase
- Depreciation: spread cost over useful life (typically 5 years for computer equipment) — better if you had a low-income year and want to defer the deduction
10. Education + continuing learning
Courses, books, conferences that maintain or improve skills for your current business. Not deductible: education that qualifies you for a new trade (MBA to switch careers isn't deductible; accounting CPE for an existing CPA practice is).
The three mistakes that draw audits
- Home office claimed on a small business that reports only losses. Combined with year-after-year losses, this is the classic "hobby masquerading as business" flag. Solution: make sure the business is net profitable in at least 3 of 5 years, or have documentation of why losses are legitimate.
- Meals equal to 20%+ of revenue. A $40k freelancer with $8k of meal deductions will get a letter. Solution: meals should be a modest fraction of total business expenses. If genuinely high (certain industries), keep impeccable logs.
- Mileage without a log. The single most common reason mileage deductions get disallowed in audit. The IRS rejects reconstructed logs done after the fact. Solution: contemporaneous log (updated weekly at minimum).
