Freelancer tax deductions in the US. What's actually claimable.

The freelancer's two tax surprises

If you've gone freelance in the last year or two, you've likely encountered the two surprises that every newly self-employed person hits.

The first surprise is self-employment tax. As an employee, your employer pays half of Social Security and Medicare tax for you; you pay the other half from your paycheck. As a freelancer, you pay both halves yourself, 15.3% of net self-employment income up to the Social Security wage base. This is on top of regular income tax. The combined hit on the first dollar of freelance profit is closer to 30% than the 22% income-tax bracket you might have been thinking of.

The second surprise is that the IRS expects you to pay it quarterly, not annually. The quarterly schedule is 15 April, 15 June, 15 September, and 15 January (of the following year). Underpaying earns you an underpayment penalty. Most new freelancers under-withhold in the first year, get hit with a penalty, and then adjust.

These two surprises make deductions matter. Every dollar of legitimate business deduction reduces your taxable freelance income, which reduces both your income tax and your self-employment tax. A $1,000 deduction is worth real money to a freelancer in a way it isn't to a salaried employee.

The big categories of freelance deductions

Schedule C is the form where freelance business income and expenses live. The expense categories are largely common-sense. Here are the ones most freelancers use.

Home office: a percentage of your home costs (rent or mortgage interest, utilities, internet, insurance) is deductible if you use a portion of your home regularly and exclusively for business. The simplified method is $5 per square foot of business use, up to 300 square feet ($1,500 max). The actual-expense method requires more record-keeping but can yield a higher deduction.

Mileage and vehicle: business-use of a personal vehicle is deductible. The standard mileage rate is the IRS-published rate (changes annually; check the IRS website for the current year). Alternatively, the actual-expense method tracks gas, maintenance, insurance, depreciation, and registration, with business-use percentage applied.

Health insurance: self-employed health insurance premiums are deductible above-the-line (a separate adjustment, not a Schedule C line). If you're paying for your own coverage (not eligible for an employer plan via you or your spouse), this is one of the biggest available deductions.

Retirement contributions: SEP-IRA, Solo 401(k), and SIMPLE IRA contributions are deductible from self-employment income. The contribution limits are far higher than a regular IRA, particularly for the Solo 401(k) which has both employee and employer contribution components.

Equipment: laptops, monitors, cameras, microphones, anything used for the business. Most can be fully expensed under §179 or bonus depreciation rather than depreciated over years.

Software and SaaS: 100% deductible if used for business. The trap is using the same subscription for personal and business; only the business-use portion is deductible.

Phone and internet: business-use percentage of your phone and home internet bills.

Education: courses, books, conferences related to maintaining or improving the skills you use in your business. Education to qualify for a new line of work is not deductible.

Travel and meals: business travel is fully deductible. Meals are deductible at 50% (subject to changing rules). Always document the business purpose.

Bank fees and merchant fees: business banking and payment-processing fees are deductible.

Subcontractor payments: if you hired other freelancers, their fees are deductible. Issue them a 1099-NEC if you paid them $600 or more in the calendar year.

Common missed deductions

These are the ones we see freelancers most often leave on the table.

The home office deduction. A surprising number of freelancers don't claim it, worried it triggers audits. Reasonable home office claims do not trigger audits in practice. Take the deduction.

QBI deduction. Most pass-through freelance businesses qualify for the 20% qualified business income deduction (IRC §199A), subject to income phase-outs. Your accountant or tax software calculates this; check it's on your return.

Self-employed health insurance. The above-the-line deduction is often missed in DIY filings. Don't.

Retirement. A Solo 401(k) lets you sock away significantly more than a traditional IRA, deduct it, and grow it tax-deferred. Worth setting up early.

Business meals. Not 100% deductible (currently 50% for most), but partially deductible. Track them.

State and local taxes paid for the business: deductible on Schedule C, not on Schedule A.

What good record-keeping looks like

The IRS doesn't care what tool you use. They care that you can produce a receipt, an invoice, or a credit-card statement entry backing every deduction you claim. Digital is fine. The general retention rule is three years from filing, six if you under-reported income, and indefinite for fraudulent or unfiled returns.

Most freelancers' record-keeping fails in one of two places: small subscriptions and cash purchases. The $9.99/month design tool no one remembers signing up for. The cab fare paid in cash on a client visit. Each one is small, but missed across a year they easily add up to $1,000–$3,000 of foregone deductions.

This is what TidyBooks is built for. Connect your email and cloud drives; we'll surface every receipt as it arrives. Take a photo of a cash receipt; we'll capture and tag it. At tax time, export the full archive to your accountant or import into TurboTax / your tax software directly.

Final word

Freelancing is a great life and a terrible accounting job. The IRS doesn't make it easier; their forms assume you have an entire small-business operation behind you. Get a tax professional in your corner for at least the first year, set up a system for capturing receipts as they arrive, and pay your quarterlies on time. The rest is mostly common sense.

Frequently asked questions

What's the difference between a deduction and a credit?

A deduction reduces taxable income; a credit reduces tax owed dollar-for-dollar. Freelance business expenses are deductions and reduce your taxable income on Schedule C. The QBI deduction (qualified business income, IRC §199A) is also a deduction but is calculated separately.

Do I need receipts?

Yes. The IRS can ask to see proof for any expense you claim. The general rule is to keep receipts for at least three years after filing; six is safer if you've under-reported income. Digital copies are fine.

When are estimated taxes due?

Quarterly. The standard due dates are 15 April, 15 June, 15 September, and 15 January (of the following year). If a date falls on a weekend or holiday, it shifts to the next business day.
