Business Expenses Freelancers Can Deduct (Complete List)

Freelancers can deduct any ordinary and necessary business expense from Schedule C income — reducing both self-employment tax (15.3%) and federal income tax simultaneously. The most valuable deductions are home office, vehicle mileage, equipment, and health insurance premiums. A freelancer earning $80,000 gross with $15,000 in deductions pays tax on $65,000 — saving approximately $4,500 in combined SE and income tax.

Business expenses freelancers can deduct

1. Home office — any space used regularly and exclusively for business qualifies. Use the simplified method ($5/sq ft, up to 300 sq ft) or Form 8829 for actual expenses.
2. Vehicle and mileage — business miles at the IRS standard rate (70¢/mile in 2025, 72.5¢/mile in 2026) or actual vehicle expenses × business-use percentage.
3. Equipment and software — laptops, cameras, monitors, SaaS subscriptions, domain registrations. Section 179 allows 100% deduction in year one.
4. Health insurance premiums — 100% deductible as an adjustment to income if you are not eligible for employer-sponsored coverage through a spouse's plan.
5. Professional services — accountant and tax preparation fees, attorney fees for business matters, bookkeeping services.

The home office deduction: simplified vs regular method

The home office deduction has two calculation methods. Most freelancers should calculate both and use the larger one:

• Simplified method: $5 per square foot of office space, maximum 300 square feet, maximum deduction $1,500. No depreciation, no Form 8829, no recapture when you sell. Best for small offices or renters.
• Regular method (Form 8829): Actual home expenses (rent or mortgage interest, utilities, repairs, insurance, property taxes) multiplied by (office square footage ÷ total home square footage). More paperwork but larger deduction for larger offices or more expensive homes. Homeowners risk a small depreciation recapture when selling.

Example: 200 sq ft office in a 1,200 sq ft apartment. Monthly rent $2,400, utilities $200. Regular method: ($2,400 + $200) × 12 × (200/1,200) = $5,200/year deduction. Simplified method: 200 × $5 = $1,000/year. Regular method wins by $4,200 here.

Section 179: deduct equipment 100% in year one

Instead of depreciating a laptop or equipment over 5–7 years, Section 179 lets you deduct the full cost in the year of purchase. The 2024 limit is $1,160,000 (well above any individual freelancer's equipment spend). Key rules:

• Equipment must be used more than 50% for business to qualify for Section 179.
• Your Section 179 deduction cannot exceed your net business income for the year.
• Bonus depreciation (80% in 2023, 60% in 2024, 40% in 2025) also allows large first-year deductions and can be used alongside Section 179.
• Mixed-use items (business + personal) only qualify for the business-use percentage. A laptop used 70% for business: deduct 70% of the cost.

Record keeping: what you need to survive an audit

The IRS requires documentation for every deduction. Keep records for at least 3 years from the date you filed (6 years if you underreported income by more than 25%):

• Receipts and invoices for all purchases — bank statements alone are insufficient for larger deductions.
• Contemporaneous mileage log — date, starting point, destination, business purpose, and miles. Reconstructed from memory is an audit red flag.
• Home office measurements — square footage documented (floor plan or measurement) and photos of the dedicated space.
• Proof of business purpose — for meals and travel, who attended and what was discussed.

Key takeaways

• Every legitimate deduction reduces both self-employment tax (15.3%) and income tax — a $5,000 deduction saves approximately $1,500–$2,000 in combined taxes for most freelancers.
• The home office deduction requires exclusive, regular business use. The simplified method ($5/sqft, max $1,500) requires no Form 8829; the regular method is larger for most but requires actual expense calculation.
• Vehicle deductions: use the standard mileage rate (70¢/mile in 2025, 72.5¢/mile in 2026) for simplicity, or actual expenses for high-cost vehicles. Track every business mile contemporaneously.
• Section 179 allows 100% equipment deduction in year one — no depreciation schedule needed for computers, cameras, and business tools used more than 50% for business.
• Health insurance premiums (for yourself, spouse, and dependents) are 100% deductible above-the-line if you are not eligible for employer coverage — this reduces AGI even without itemising.
• Business deductions only reduce income tax and SE tax — they do not eliminate the need to pay quarterly estimated taxes. The quarterly tax filing guide shows how to estimate your tax liability after deductions and make the correct quarterly payments.

Frequently asked questions

What business expenses can freelancers deduct?

Freelancers can deduct ordinary and necessary business expenses on Schedule C: home office, vehicle mileage or actual expenses, equipment and software, marketing and advertising, professional development, business insurance, professional services (CPA, attorney), 50% of business meals, business travel, and 100% of self-employed health insurance premiums. All deductions require documentation and a clear business purpose.

How does the home office deduction work?

The home office deduction requires a space used regularly and exclusively for business. Simplified method: $5/sq ft × office square footage (max 300 sq ft, max $1,500/year). Regular method: total home expenses × (office sq ft ÷ total sq ft) — larger for most freelancers with sizeable dedicated spaces. Choose the method that gives the larger deduction; recalculate each year.

Can I deduct my car as a freelancer?

Yes — the business-use portion of your vehicle is deductible. Standard mileage rate (72.5¢/mile in 2026) is simpler and includes all vehicle costs. Actual expenses (gas, insurance, repairs, depreciation × business-use %) is better for expensive, fuel-inefficient vehicles. You must choose standard mileage in the first year of owning the vehicle to use it later; switching to actual expenses locks you in for that vehicle's life.

Is a dedicated business phone deductible?

The business-use percentage of your cell phone is deductible on Schedule C. If you use your phone 60% for business and 40% personal, deduct 60% of the bill. A second phone used exclusively for business is 100% deductible. The IRS scrutinises 100% personal phone deductions — document your business use percentage with evidence.

What happens if I am audited for freelance deductions?

In an audit, you must substantiate every deduction with documentation: receipts, bank statements, mileage logs, invoices, and records of business purpose. The home office deduction and vehicle deduction are among the most scrutinised. Keep records for at least 3 years from your filing date (6 years if you may have underreported by more than 25%). Contemporaneous records are far more credible than reconstructed ones.
