You paid for a laptop, a co-working desk, half your phone bill, and a software subscription this year — and you have no idea which of those count as freelance tax deductions. Most freelancers either write off too little out of fear, or too much because a friend said "just deduct it." Neither approach survives an audit, and both cost you money.
The rule that decides it all is short: a business expense is deductible if it's ordinary (common in your line of work) and necessary (helpful for running your business), per IRS Publication 334. It doesn't have to be indispensable — just legitimately tied to earning your income. Below is the full list freelancers actually use, with the 2026 numbers attached.

Home Office: The Deduction Freelancers Skip Most
If part of your home is used regularly and exclusively for your freelance work, you qualify — a spare bedroom that's also a guest room breaks the "exclusive" test, but a dedicated desk nook usually passes. The simplified method is the one most freelancers should use: $5 per square foot of office space, up to 300 square feet, for a maximum deduction of $1,500, per the IRS simplified home office option.
The alternative is the regular method — actual percentage of rent, utilities, and home insurance based on office square footage divided by total home square footage. It's more paperwork but can be worth more if your home office is large or your rent is high. Run both numbers once a year; whichever is bigger, use that one. You're allowed to switch methods year to year.
Vehicle and Mileage — Watch the Rate Change Mid-Year
2026 is an unusual year for mileage. The IRS set the standard rate at 72.5 cents per mile for travel from January 1 through June 30, per its initial 2026 rate announcement. It then raised the rate to 76 cents per mile effective July 1 through December 31, citing rising fuel prices. That is a rare mid-year adjustment, per Announcement 2026-11. If you drove to a client meeting in March and another in September, those two trips get logged at different rates.
Keep a running log — date, destination, business purpose, and miles — for every trip. "Client meetings, roughly 3,000 miles this year" won't survive a review; a dated log will. The whole log can be a spreadsheet with five columns:
| Date | From → To | Business purpose | Miles | Rate |
|---|---|---|---|---|
| Mar 12, 2026 | Home office → Client HQ, Midtown | Kickoff meeting, Acme rebrand | 18 | 72.5¢ |
| Sep 3, 2026 | Home office → Studio rental | Product shoot, Acme catalog | 26 | 76¢ |
Commuting from your home office to a coworking space you use daily doesn't count as business mileage in most cases. Driving from your home office to a client's office, a shoot location, or a supply run does.
Software, Subscriptions, and Tools of the Trade
This is the deduction most freelancers already claim, and it's broad: your invoicing tool, design software, project management app, cloud storage, and any subscription you'd cancel if you stopped freelancing tomorrow. The test is the same "ordinary and necessary" standard — a photographer's Lightroom subscription and a developer's IDE license both qualify under the same rule.
Buy hardware — a laptop, a camera, a second monitor — and you generally deduct it the year you place it in service. You do that either through Section 179 expensing (deduct the full cost this year instead of depreciating it over several) or standard depreciation, per IRS Publication 946. Keep the receipt; "I bought a laptop sometime this year" isn't documentation, but a dated invoice or receipt is. If cash changed hands, a receipt for your own files closes that gap.
Health Insurance — Bigger Than Most Freelancers Realize
If you're self-employed and not eligible for an employer-subsidized plan (including a spouse's), you can deduct 100% of your health insurance premiums — for yourself, your spouse, and your dependents. It's an adjustment to income on Schedule 1, not an itemized deduction, per the Instructions for Form 7206. That distinction matters: you get this write-off whether or not you itemize. One thing it does not do is lower your self-employment tax — the IRS is explicit that you can't subtract it when figuring net earnings from self-employment, so it saves income tax only.
This deduction is capped at your net self-employment profit for the year, after subtracting the deductible half of your self-employment tax and any SEP or Solo 401(k) deduction. You can't deduct more in premiums than the business actually netted. The IRS doesn't give you a carryforward for premiums above that cap. Instead, the excess can be claimed as a medical expense on Schedule A if you itemize, subject to the usual AGI floor (only medical costs above a percentage of your adjusted gross income count). If a slow year with high premiums puts you there, it's worth a CPA conversation about whether itemizing beats the standard deduction.
Retirement Contributions Do Double Duty
Every dollar you put into a SEP-IRA or Solo 401(k) is both a retirement contribution and a current-year deduction. For 2026, the combined contribution ceiling across these plans is $72,000, up from $70,000 in 2025, per IRS Notice 2025-67. A SEP-IRA caps you at 25% of net self-employment earnings, up to that $72,000 ceiling. A Solo 401(k) lets you contribute up to $24,500 as an "employee" plus a further employer-side contribution. If you're 50–59 or 64 and older, you can add an $8,000 catch-up; at 60–63 the catch-up is $11,250.
Freelancers with an inconsistent income year often overlook this because it feels like a December decision, not a January one. It's the rare deduction you can still act on after the calendar year mostly closed — a SEP-IRA can be funded up until your filing deadline, extensions included (IRS SEP plan FAQs).
The Self-Employment Tax Deduction Nobody Explains Well
Every freelancer pays 15.3% in self-employment tax on net earnings — 12.4% for Social Security and 2.9% for Medicare, per the IRS page on self-employment tax. The Social Security part stops at the $184,500 wage base for 2026; the Medicare part has no cap (IRS Tax Topic 751). What catches people off guard is that you then get to deduct half of that — the "employer's share" — from your income, mirroring what a W-2 job would have split with an actual employer. It's calculated automatically on Schedule SE; you don't have to track it separately, but it's worth knowing it's there so your tax software's number doesn't look like a mistake.
The QBI Deduction — 20% Off the Top for Most Freelancers
On top of every expense above, most freelancers also qualify for the Qualified Business Income deduction. It's worth up to 20% of your net business income, taken as a separate deduction whether or not you itemize (IRS: Qualified Business Income deduction). It was made permanent by section 70105 of the One Big Beautiful Bill Act (Public Law 119-21). For 2026 it phases out for high earners starting at $201,750 (single/head of household) or $403,500 (married filing jointly), per Revenue Procedure 2025-32. The phase-out is complete at $276,750 and $553,500 respectively. Married-filing-separately uses its own range — $201,775 to $276,775 — so check your filing status against the table before relying on a number here.
Most freelancers billing under six figures clear this without thinking about it. If you're close to the threshold, two moves matter: timing a big invoice into January instead of December, or maxing out a SEP-IRA contribution to lower net income. Either can be the difference between the full 20% and a partial phase-out. Run that timing past a CPA first; it interacts with your estimated payments and the rest of your return.
Common Deductions Freelancers Underclaim
These are the Schedule C deductions that get skipped most. The rules below come from IRS Publication 334 unless another source is linked; line numbers follow the current Schedule C.
| Deduction | Rule or limit | Schedule C line |
|---|---|---|
| Business meals | 50% of the cost when you're meeting a client or traveling for work; keep the receipt and note who you met (IRS Publication 463) | Line 24b |
| Business travel | Airfare, lodging and transport for trips away from your tax home (the city where you normally work) that are primarily for business | Line 24a |
| Advertising and marketing | Website hosting, paid ads, portfolio printing, business cards | Line 8 |
| Business insurance | Professional liability, errors and omissions, equipment coverage | Line 15 |
| Legal and professional fees | Your CPA's fee, contract review by a lawyer, bookkeeping | Line 17 |
| Office supplies | Paper, ink, small tools, consumables you use up within the year | Line 22 |
| Bank and payment processing fees | The percentage Stripe or PayPal takes, and any business-account monthly fee | Line 10 or 27b |
| Phone and internet | The business-use percentage only, not the whole bill | Line 25 or 27b |
| Professional development | Courses, conferences and certifications tied to your existing freelance work, not training for a new career | Line 27b |
| Contractor and subcontractor payments | Money you paid someone else to help deliver client work | Line 11 |
| Start-up costs | Up to $5,000 of costs from before you opened for business can be deducted in your first year (reduced once total start-up costs pass $50,000); the rest is amortized over 180 months (Schedule C instructions, Part V) | Line 27b |
What Freelancers Get Wrong — and What It Costs
The most common mistake isn't claiming too much; it's claiming too little out of fear, then overpaying every April. The second most common mistake is the opposite: writing off 100% of a phone bill or car payment that's genuinely half personal use. Both errors are avoidable with the same habit — track the expense the week it happens, not the week before you file.
Real example: A designer bills $68,000 in 2026. Simplified home office: $1,500. Business mileage: 2,200 miles January–June at 72.5¢ = $1,595, plus 1,800 miles July–December at 76¢ = $1,368. Software and hardware receipts: $2,400. Those four lines total $6,863, so net profit before the self-employment-tax and health-insurance adjustments is $61,137 instead of $68,000. Self-employment tax runs on 92.35% of net profit, so skipping those deductions would have cost roughly $970 in extra self-employment tax alone — before income tax even enters.
If you're still deciding cash vs. accrual accounting for your books, cash basis makes this tracking simpler for most solo freelancers — you record the expense when the money actually leaves your account. And once you know what you're deducting, revisit quarterly estimated taxes — a bigger deduction list this year usually means a smaller quarterly payment next year.
Frequently Asked Questions
Do I need a receipt for every deduction?
Yes, in practice. "No receipt, no deduction" is the safer habit across the board — a bank or card statement plus a note of the business purpose is the minimum for anything you'd need to defend later.
Can I deduct my home internet if I also use it personally?
Yes, but only the business-use percentage. If you estimate you use it 40% for freelance work, deduct 40% of the bill — and be ready to explain how you arrived at that percentage.
Is the home office deduction an audit red flag?
Not inherently. It's a normal, well-documented deduction as long as the space is used regularly and exclusively for business — the rule the IRS checks closely if you're ever asked to substantiate it.
What if I had a loss this year — can I still deduct expenses?
Generally yes. Business expenses reduce your taxable income even in a loss year, and the loss itself can often offset other income on your return. Talk to a CPA if the loss is large or recurring across multiple years.
Should I use a CPA or tax software for freelance deductions?
Tax software works fine for a straightforward year with a handful of standard deductions. A CPA earns their fee once your situation includes retirement plan choices, a home office plus a vehicle, or income near the QBI phase-out threshold — the judgment calls are where a professional pays for itself.
Freelance Tax Deductions Only Work If You Can Prove Them
Every freelance tax deduction on this list depends on the same habit: documentation, tracked as you go instead of reconstructed in April. Pair a free invoice generator for the income side with a receipt for every business purchase, and you'll walk into tax season with a number you already trust.
Tax rules vary by individual circumstance and can change with future legislation. This covers the general federal framework as of 2026; for your specific numbers, a CPA who works with freelancers is worth the fee.
