The difference between a freelancer who pays 35% effective tax rate and one who pays 22% often comes down to which deductions they're actually taking. Most freelancers claim the obvious ones — software, a laptop. The ones who do this well take all of them.
Here's the complete list for 2024, with the rules that matter.
Home Office Deduction
Two methods: simplified ($5/sqft, max 300 sqft = $1,500 cap) or regular (actual expenses × business-use percentage).
The regular method wins for most freelancers who pay market-rate rent or have a meaningful mortgage. At $2,500/month rent with a 15% office ratio, that's $4,500/year — triple the simplified cap.
The requirement that kills most claims: exclusive use. Your office must be used only for business. A guest room that also holds your desk doesn't count. A dedicated room used solely for work does.
Vehicle and Mileage
Standard rate: 67 cents per mile for business driving in 2024.
What counts: client meetings, business errands, driving between job sites, trips to the post office for business mail, sourcing trips for inventory. What doesn't: commuting to a regular fixed office.
You must keep a mileage log — date, destination, business purpose, and miles. The IRS can ask. Apps like MileIQ automate this; a Google Sheet works too. Estimating in April from memory is not a log.
Alternative: actual vehicle expenses (gas, insurance, depreciation, maintenance, registration) × business-use percentage. Better for expensive vehicles or EVs with high depreciation.
Self-Employed Health Insurance Deduction
If you pay for your own health insurance (individual market, COBRA, or any qualified plan), you can deduct 100% of premiums paid for yourself, your spouse, and dependents — as an above-the-line deduction on Schedule 1 (IRC §162(l)).
This reduces your adjusted gross income — which affects your tax bracket, your ACA premium subsidy eligibility, and the Medicare Additional Tax threshold.
The catch: you can't deduct more than your net self-employment income for the year. If you had $15,000 in net SE income and paid $18,000 in premiums, your deduction is capped at $15,000.
This deduction saves income tax but not SE tax. The premium doesn't reduce Schedule C net profit.
Retirement Contributions
SEP-IRA: Contribute up to 25% of net self-employment income (after the SE tax deduction) or $69,000 — whichever is less. For $100,000 net SE income, that's approximately $18,587. Contributions reduce your AGI dollar for dollar.
Solo 401(k): The most powerful retirement vehicle for self-employed individuals. Two contribution types:
- Employee deferral: up to $23,000 in 2024 ($30,500 if age 50+)
- Employer profit-sharing: up to 25% of net SE income
Combined limit: $69,000 in 2024. On $100,000 net SE income, you could potentially contribute $23,000 (employee) + $18,587 (employer) = $41,587. On $120,000 net income: $23,000 + $22,300 = $45,300.
Retirement contributions do not reduce SE tax — only income tax. But they're still the highest-leverage deduction available to most freelancers.
Equipment and Technology (Section 179)
Equipment purchased for business use can typically be deducted in full in the year purchased, under Section 179 (up to $1,160,000 for 2024) or bonus depreciation (60% in 2024, phasing down from 100%).
Examples:
- Computer, laptop, monitor, keyboard
- External drives, docking stations, webcams
- Desk, ergonomic chair, standing desk (if used exclusively in your home office)
- Camera equipment (if used for business — content creation, product photos)
- Microphone, audio interface (podcasting, video calls)
If the equipment is used for both personal and business purposes, you can only deduct the business-use percentage. Document your business use ratio.
Software and Subscriptions
Any software or subscription used exclusively or primarily for business is deductible:
- Figma, Adobe Creative Cloud, Sketch, Canva
- GitHub, VS Code extensions, developer tools
- Slack, Notion, Asana, Linear, Trello
- Zoom, Loom, Calendly
- QuickBooks, FreshBooks, Wave, accounting tools
- Cloud storage (iCloud, Google Drive, Dropbox) — business portion
- Stock photo subscriptions, font licenses
Annual subscriptions paid in December for next year may need to be allocated — consult your accountant on timing.
Professional Development
Business-related education and training is deductible:
- Online courses (Udemy, Coursera, LinkedIn Learning, Masterclass — if business-relevant)
- Books and technical publications related to your work
- Industry conferences and trade shows (including travel and hotel)
- Professional certifications and exam fees
The line: the course must maintain or improve your current professional skills. Learning a completely new career doesn't qualify. Deepening existing skills does.
Business Meals
50% of business meal costs are deductible — when there's a clear business purpose and a client, colleague, or business associate present.
Documentation: date, location, amount, who attended, and the business purpose discussed. Credit card records plus a brief note in your calendar work.
The old "entertainment" deduction is gone — tickets to sporting events, concerts, golf rounds are no longer deductible. Meals associated with those events still qualify at 50% if documented separately.
Phone and Internet
If you use your personal phone and home internet for business, you can deduct the business-use percentage.
A common approach: if you use your phone 40% for business calls, messaging, and apps, deduct 40% of your monthly bill. Same principle for internet. There's no bright-line rule from the IRS on percentage — just be reasonable and consistent.
If you have a separate business phone line, 100% is deductible.
Professional Services
- Accountant/CPA fees: fully deductible for the portion attributable to business tax preparation and advice
- Attorney fees: business-related legal work (contracts, IP, business formation)
- Financial advisor: fees for business-related advice (note: personal investment advice is not deductible)
Bank and Payment Processing Fees
- Business bank account monthly fees
- Credit card processing fees (Stripe, Square, PayPal)
- Wire transfer fees for business transactions
If you use a business credit card, the annual fee is deductible to the extent the card is used for business.
The Bottom Line
The average freelancer who tracks carefully deducts $15,000–$30,000 in legitimate expenses annually. At a 22% federal income tax rate plus SE tax on the Schedule C reduction, that's $4,500–$9,000 in real tax savings. The work required: a receipt folder, a mileage log, and a monthly 15-minute expense review.
Take the deductions you've earned.
