Tax Deductions Every Freelancer Should Know

Deductions are how freelancers legally lower their tax bill: every dollar of legitimate business expense reduces the income you're taxed on. Many new freelancers overpay simply because they don't track what they're entitled to claim. Here are the common ones.

The rule of thumb

A business expense is generally deductible if it's ordinary and necessary for your work. The key habit isn't memorizing rules — it's keeping records: save receipts, separate business and personal spending (a dedicated business account helps), and log expenses as you go.

Common freelance deductions

• Home office. If you use part of your home regularly and exclusively for work, you can deduct a portion of rent/mortgage, utilities, and insurance — or use the simplified square-footage method.
• Equipment and supplies. Computer, monitor, phone, desk, and the tools of your trade.
• Software and subscriptions. Design tools, accounting apps, hosting, professional memberships.
• Self-employed health insurance. Premiums for you and your family are often deductible above the line — see health insurance for freelancers.
• Retirement contributions. SEP-IRA or Solo 401(k) contributions reduce taxable income — see SEP-IRA vs Solo 401(k).
• Half of self-employment tax. You deduct half of what you pay; details in self-employment tax explained.
• Phone and internet (the business-use portion).
• Professional services — your accountant, lawyer, and business banking fees.
• Education that maintains or improves your current skills.
• Business travel and mileage for client work.
• Marketing — your website, ads, and portfolio costs.

Don't overlook the QBI deduction

On top of expenses, most freelancers can take the 20% qualified business income deduction, which lowers taxable income further. It's separate from your expense deductions — see the QBI guide.

Track it, don't reconstruct it

The freelancers who claim the most aren't the most aggressive — they're the most organized. Logging expenses through the year (rather than guessing in April) means you capture everything and can back it up. A simple spreadsheet or accounting app works; pair it with quarterly tax planning so deductions feed straight into your estimates.

Know the line

Deductions must be real business expenses — don't claim personal costs. When something is mixed (a phone, a car, a home), deduct only the business-use share. If you're unsure, a tax professional will usually save you more than they cost.

Deductions are one of the biggest financial advantages of self-employment. Track them well and you keep more of what you earn — legitimately.
