Tax Deductions Every Freelancer Should Know

Every dollar you deduct is a dollar you don't pay self-employment tax (15.3%) or income tax on. For a freelancer in the 22% federal bracket, a $1,000 deduction saves roughly $373 in combined taxes. Most self-employed people leave thousands on the table every year simply because they don't know what qualifies. Here's the comprehensive list.

The Big Three: Deductions That Save the Most

1. Vehicle / Mileage Deduction

If you drive for business — client meetings, supply runs, travel between work sites, deliveries — you can deduct vehicle expenses. You have two options: the standard mileage rate ($0.70 per mile for 2026) or actual expenses (gas, maintenance, insurance, depreciation, proportional to business use). Most freelancers find the standard mileage rate simpler and often more generous.

At $0.70/mile, a freelancer driving 15,000 business miles per year gets a $10,500 deduction — saving roughly $3,900 in taxes (at the 22% bracket + 15.3% SE tax). The key requirement is a contemporaneous mileage log. Apps like MileIQ, Everlance, or a simple spreadsheet work. The IRS will disallow the deduction without documentation.

What counts: Driving to client locations, job sites, business meetings, the post office for business mail, the bank for business deposits, and supply stores. What doesn't count: Your regular commute from home to a fixed office (but if your home IS your principal place of business, all business trips from home qualify).

2. Home Office Deduction

If you use a portion of your home regularly and exclusively for business, you can deduct home office expenses. There are two methods:

Simplified method: $5 per square foot of your office, up to 300 square feet. Maximum deduction: $1,500. No complex calculations needed. This is what most freelancers should use.

Actual expense method: Calculate the percentage of your home used for business (office square footage / total home square footage), then apply that percentage to your mortgage interest or rent, property taxes, utilities, home insurance, repairs, and depreciation. This produces a larger deduction if you have a big home office or high housing costs, but requires more record-keeping.

The critical requirement is "regular and exclusive use" — the space must be used only for business, not as a guest bedroom that doubles as an office. A dedicated room is ideal, but a clearly defined portion of a room also qualifies if it's exclusively used for work.

3. Self-Employed Health Insurance Deduction

If you're self-employed and pay for your own health insurance (and aren't eligible for coverage through a spouse's employer), you can deduct 100% of premiums for medical, dental, and vision insurance for yourself, your spouse, and your dependents. This is an above-the-line deduction — it reduces your AGI, which can affect other deductions and credits too.

At average family premiums of $1,200-1,800/month, this deduction is worth $14,400-21,600 per year — potentially the single largest deduction a self-employed person can take.

Retirement Contributions

SEP-IRA

Contribute up to 25% of your net self-employment income (after the SE tax deduction), up to $69,000 for 2026. Easy to set up, easy to administer, and contributions are fully deductible. The downside: no catch-up contributions for those over 50.

Solo 401(k)

Allows both employee contributions ($23,500 for 2026, plus $7,500 catch-up if over 50) and employer contributions (25% of net SE income). Total limit: $69,000 (or $76,500 with catch-up). More complex to set up but allows higher contributions at lower income levels than a SEP-IRA.

Business Operating Expenses

Any expense that is "ordinary and necessary" for your business is deductible. Here's what that means in practice:

Software and subscriptions: Adobe Creative Suite, Microsoft 365, accounting software (QuickBooks, FreshBooks), project management tools, cloud storage, domain names, hosting, and any SaaS tools you use for business.

Equipment and supplies: Computers, monitors, printers, office furniture, office supplies, and peripherals. Items over $2,500 may need to be depreciated, but Section 179 lets you deduct the full cost of most business equipment in the year of purchase.

Phone and internet: The business-use percentage of your phone bill and home internet. If you use your phone 70% for business, you can deduct 70% of the bill. A separate business phone line is 100% deductible.

Professional services: Accountant and CPA fees, legal fees related to your business, bookkeeping services, and tax preparation fees (for the business portion of your return).

Marketing and advertising: Website costs, business cards, online advertising (Google Ads, Facebook Ads), social media tools, email marketing platforms, and networking event fees.

Education and training: Courses, workshops, conferences, books, and subscriptions that maintain or improve skills used in your current business. (A web developer taking a React course: deductible. The same developer taking a culinary class: not deductible.)

Insurance: Business liability insurance, professional indemnity insurance, errors and omissions insurance, and commercial property insurance.

Travel: Airfare, hotels, rental cars, and 50% of business meals when traveling overnight for business. The travel must be primarily for business purposes.

Business meals: 50% of meals with clients, prospects, or business associates where business is discussed. Keep the receipt and note who you met with and the business purpose. (The 100% restaurant meal deduction from 2021-2022 has expired.)

Tax-Specific Deductions

Half of self-employment tax: You automatically deduct the employer-equivalent portion (half) of your SE tax from your AGI. On $100k of net SE income, this saves roughly $7,065 off your AGI. This happens on your 1040, not Schedule C.

Qualified Business Income (QBI) deduction: Eligible self-employed filers can deduct up to 20% of their qualified business income. For a freelancer earning $80,000 net, that's up to $16,000 off taxable income. There are income limits where this phases out or requires additional calculations (above $191,950 single / $383,900 MFJ for 2026), but most freelancers are well under the threshold.

Commonly Missed Deductions

These are the deductions that even experienced freelancers often forget: bank fees and merchant processing fees on business accounts, parking and tolls for business trips, postage and shipping costs, business license and permit fees, state and local business taxes, professional association memberships and dues, and the cost of a dedicated coworking space or desk rental.

Record-Keeping Rules

The IRS can disallow any deduction you can't substantiate. The standard: keep receipts for any expense over $75, maintain a contemporaneous mileage log, keep bank and credit card statements showing business purchases, and retain records for at least 3 years after filing (7 years if you want to be safe). Using a dedicated business bank account and credit card makes this dramatically easier — every transaction on those accounts is automatically documented as a business expense.
