Freelancer Tax Deductions: What You Can Claim, What You Can't (US)

DRAFT — NOT CPA/LEGAL-REVIEWED — in Compliance HOLD until a qualified CPA/legal reviewer is engaged; do not describe as reviewed.

Educational only. This guide explains a system; it is not personal advice for your situation. Before you act on any tax or retirement figure here, consult a tax professional.

Short answer: This guide is about United States federal tax only. A deductible business expense is an ordinary and necessary cost of running your freelance work — ordinary meaning common in your line of work, necessary meaning helpful and appropriate, not indispensable. Claim it only if you can show the amount, the date, and the business purpose. Anything you cannot show that for is a guess, and guesses are what get disallowed. No deduction in this guide is guaranteed to be allowed for any particular reader — the rules, and your records, decide that. Educational only — consult a tax professional for your situation.

Key takeaway. A deductible expense must be ordinary and necessary, and you must be able to show the amount, the date, and the business purpose.

Watch out. Anything you cannot show that for is a guess — and guesses are what get disallowed.

Who this is for: You track some expenses and suspect you are missing others, or you are not sure which of the things you already pay for count. You want a checklist you can run through at year-end without turning it into a wish list.

Who this is not for: Employees claiming unreimbursed work costs, and anyone looking for a list of loopholes. This is a freelancer Schedule C checklist, and it stays inside ordinary business costs.

The record-keeping test, before the list

Every category below is judged by the same test. Keep the receipt or invoice, note the business purpose in plain words at the time, and keep the record long enough to answer a question about it later. A card statement alone often shows the amount and the seller but not the purpose. A receipt with "client X website hosting, March" written on it does. If a cost is mixed — part business, part personal — only the business part belongs on the return, and you need a reasonable way to split it, written down, not reconstructed from memory in April.

Deductions lower net profit. That matters twice: a lower net profit means lower income tax and lower SE tax, because SE tax is worked out from net profit (see Guide B3). That is also why inventing expenses is so costly in reverse — it understates both taxes at once.

Home office: simplified method vs actual method

This is the deduction people most often get wrong in both directions — claiming a whole flat, or claiming nothing because the rules sound strict.

The home-office deduction requires regular and exclusive use: a space you use regularly for business, and only for business. A spare room used only as an office qualifies in the usual telling. A kitchen table cleared for work in the evening and used for family meals the rest of the day does not, because the use is not exclusive. Regular means ongoing business use, not a one-off afternoon.

Once regular-and-exclusive use is met, there are two ways to work out the amount:

	Simplified method	Actual (regular) method
How it works	$5 per square foot of office space	Business share of actual home costs: rent or mortgage interest, utilities, insurance, repairs, and similar costs
Cap	Maximum 300 square feet, so maximum $1,500	No $1,500 cap; the amount follows your actual costs and business share
Measuring	Measure the office area, up to 300 sq ft	Measure office area as a share of the whole home, then apply that share to each cost
Records	Square-footage measurement and evidence of regular-and-exclusive use	Bills and receipts for each home cost, plus the area calculation
Depreciation	No depreciation claim under the simplified method	Depreciation on the business portion of the home may come into play — with later consequences on a sale that need professional advice

Worked comparison, same office: a 120-square-foot room used only for work.

Simplified: 120 × $5 = $600.
Actual, illustrated: if total home costs for the year are $18,000 and the office is 10% of the home by area, the business share is $1,800 — before any depreciation or exclusions are considered.

In that illustration the actual method gives more. In a cheap-rent home, or a small office, the simplified $600 can win, or come close, with far less paperwork. The point is not that one method is always better. It is that you pick by running both numbers on your real costs, and you can only run the actual method if you kept the bills. If you rent, ask how your landlord's costs and your own bills split before assuming the actual method is available to you in full — consult a tax professional on the details of your housing situation.

Health insurance premiums: what they do, and what they do not do

A self-employed person who meets the conditions can deduct health insurance premiums paid for themselves, a spouse, and dependents under age 27 — as an adjustment to income, not as a Schedule C business expense. That placement matters, and it trips people up:

It lowers income tax, because it lowers adjusted gross income.
It does not lower SE tax, because SE tax is worked out from Schedule C net profit before that adjustment.

Take a fictional freelancer, Sam, who pays $4,800 a year in qualifying premiums. Her Schedule C profit is unchanged by that $4,800. Her income-tax calculation starts $4,800 lower. Her SE tax is exactly what it would have been without the premiums. Anyone who subtracts premiums from profit before working out SE tax has understated SE tax.

Conditions apply — for example, the deduction is generally not available for months when you were eligible to take part in a subsidized health plan through a spouse's employer or your own employer — so check eligibility month by month rather than assuming a full year. The premium figure itself must be premiums actually paid, not a quoted price.

Software subscriptions: small lines that add up

Software you pay for to do the work is a classic ordinary business cost: design tools, writing tools, accounting software, scheduling tools, cloud storage for client files, and similar subscriptions. The trap is not whether they count in principle. It is that they are small, monthly, and easy to forget at year-end, or easy to over-claim when a tool is also personal.

A realistic example: $29 a month for a design tool, $15 a month for accounting software, and $12 a month for client-file storage. That is $56 a month, or $672 for the year. On its own, no single line looks worth chasing. Together, they move net profit by $672 — and, at the 14.13% SE rate below the wage base, by about $95 of SE tax alone, plus whatever income-tax effect follows.

The record-keeping test here is simple: the subscription receipt or annual statement, plus a one-line note of what the tool does for the business. For a mixed-use tool — a storage plan that holds family photos and client files — claim only the business share, with the split written down. Cancelling a tool you stopped using is also a deduction decision: a subscription still running in December is still a cost, but it is money leaving for nothing.

Commonly missed deductions

These are the lines freelancers most often leave off, not because they are exotic, but because they never reach a single tidy invoice:

Business portion of phone and internet. If a phone or connection serves both work and personal life, only the business share counts. A freelancer who can show, say, a consistent work share from call logs or a separate work line has a defensible figure. A freelancer who claims 100% of a family plan without a basis does not.
Business bank and payment-processing fees. Account fees for a business account, and the processing cut taken from client payments, are business costs. They are easy to miss because they never arrive as a bill — they are already taken out before the money lands.
Professional development that serves your current work. A course, book, or conference that maintains or improves skills for the work you already do is a different matter from training for a new profession. Keep the programme or receipt and a note of how it connects to current clients.
Business insurance. Professional liability or similar cover bought for the freelance work is a business cost, where applicable to your work.
Payments to contractors you hired. If you paid another freelancer to help on a client job, that payment is a business cost of yours, and you may separately have information-reporting duties for it. Keep the contract, the invoice, and proof of payment together.
Office supplies and small equipment. The printer paper, the replacement cable, the desk lamp for the office — small, receipt-level costs that are easy to drop. A year of them is not small.

None of these is automatic. Each one still has to pass the record-keeping test: amount, date, business purpose, and, where mixed, a defensible split.

Mileage: a rate you must date-check before you use it

Vehicle costs for business travel can be worked out by actual expenses or by the IRS standard mileage rate — a per-mile figure multiplied by business miles. Do not use a mileage rate you saw quoted somewhere without checking which period it covers, because the 2026 story has two chapters and this draft could only verify one of them from an official IRS page at the time of writing.

What was verified from an official source: IRS news release IR-2025-128 (29 December 2025) set the 2026 business standard mileage rate at 72.5 cents per mile from 1 January 2026, up from 70 cents in 2025. That figure is dated and sourced, and it is the only mileage figure this guide uses in a worked example — and only for miles in that January period.

What was not verified from an official IRS page in this check: a mid-year increase reported in secondary coverage during 2026, said to raise the business rate for travel on or after 1 July 2026. Because that second-half figure could not be confirmed from an IRS publication or notice in this check, this guide does not state any single 2026 mileage rate as current for the whole year, and you must not use one from this guide without checking the IRS rate for the exact dates you drove — see IRS Notice 2026-10 and any later IRS announcement for the period in question, and consult a tax professional if the periods straddle a change.

Worked example, period-labelled only: 4,000 business miles driven in the January 2026 period at the verified 72.5-cent rate:

4,000 × $0.725 = $2,900.

That example is not a full-year figure. Miles driven later in 2026 may fall under a different rate, and mixing periods into one multiplication is the error to avoid.

Whichever method you use, the log is the deduction. Date, destination, business purpose, and miles, recorded at the time — not rebuilt in April. Commuting from home to a regular workplace is personal travel, not business mileage, and home-office rules change how that line is drawn for a home-based freelancer; if your travel pattern is unusual, check it with a professional rather than assuming every drive counts.

What not to claim

Some costs feel work-related and still do not belong on a Schedule C. Claiming them does not make them deductible, and a pattern of them is worse than a single error because it suggests the return was not checked:

Commuting to a regular workplace, and the personal portion of any mixed trip.
The personal share of rent, utilities, phone, or internet — only the business share counts.
General clothing, grooming, or a wardrobe that is suitable for everyday wear, even if you also wear it to client meetings.
Personal meals, family meals, and entertainment. Business meals have their own rule — see below — but a meal is not deductible just because you talked about work during it.
Fines, penalties, and personal gifts.
The full cost of a home, a car, or a device that is also personal, claimed at 100% without a business split.
Costs of a hobby presented as a business, and start-up wishes with no business activity behind them.

Meals, specifically: business meals are generally limited to 50% of the cost, and only where the meal has a genuine business purpose with a record of who was present and what was discussed. A $80 client lunch, properly documented, is a $40 deduction under that limit — not $80, and not $0 by default either. Keep the receipt and the note together.
