Freelance Tax Deductions: What Actually Counts, and What Gets Disallowed
A deduction saves a freelancer around 30 cents on the dollar, not 22. Here is what qualifies, what does not, and the records that make it stick.

The standard the IRS applies is two words: ordinary and necessary.
Ordinary means common in your line of work. Necessary means helpful and appropriate — not indispensable. The IRS guidance on deducting business expenses is the source, and it is broader than most people assume.
Deductions are worth more to you than to an employee
This is the bit worth internalising. A business deduction reduces the profit that both income tax and self-employment tax are charged on.
So a $1,000 expense costs you roughly $695 after tax. Not $780.
Why not the full 22% plus 14%? A smaller profit also shrinks two other deductions: the one for half of your self-employment tax, and the 20% QBI deduction most freelancers get. So only about three-quarters of each deducted dollar comes off your taxable income. It is the same arithmetic in reverse as the extra tax on your next $1,000.
That changes the maths on marginal purchases — but not as much as people want it to. Which brings us to the thing worth saying plainly.
A deduction is not a rebate
Spending $1,000 to save about $305 still leaves you about $695 poorer. "It's a write-off" is not a reason to buy something. It is a discount on things you were going to buy anyway.
The ones almost every freelancer has
- Software and subscriptions — design tools, hosting, domains, IDEs, cloud storage
- Hardware — laptop, monitor, desk, chair, phone (business share)
- Professional insurance — liability, errors and omissions
- Accounting and legal fees — including your tax preparation, for the business portion
- Bank and payment processing fees — Stripe, PayPal, Wise, business account charges
- A qualifying home office — see the exclusive-use test below
- Business mileage — at the standard rate, or actual expenses
- Training directly related to your current work
- Phone and internet — the business share, not the whole bill
The ones with conditions
Meals are 50% deductible when there is a genuine business purpose: a meal with a client or business contact, or a meal while you are travelling away from home overnight for work. Lunch alone at your desk on an ordinary day is not a business meal.
Travel is deductible when the primary purpose of the trip is business. A conference with a weekend attached is fine; a holiday with one client call is not.
Clothing is deductible only if it is unsuitable for everyday wear. A branded uniform qualifies. A suit does not, however much you only wear it to meetings.
Education is deductible if it maintains or improves skills for your current business. Training that qualifies you for a new career is not deductible, which is the line that catches career-changers.
Home office requires regular and exclusive use. The IRS is explicit that the space must be used only for business — a spare room that doubles as a guest room fails, whatever proportion of the time it is a guest room.
The ones that get disallowed
- Commuting from home to a regular workplace
- Personal phone and internet in full, without a business-use split
- Clothing you could wear anywhere
- Anything you cannot substantiate
- A percentage you invented because it sounded reasonable
That last one matters more than the others. Most deductions fail not because the expense was ineligible but because the business-use percentage had nothing behind it.
What good records look like
For a pure business expense: the receipt or a statement line. For mixed use: whatever shows how you arrived at the split — a month of logged usage, a count of business versus personal trips, the square footage measurement. You do not need to log every day of the year. You need one defensible sample and a consistent method.
The big-ticket wrinkle
Items over roughly $2,500 may need to be capitalised and depreciated over several years rather than deducted in one — though Section 179 and bonus depreciation often let you take the whole thing up front.
If you are buying a $4,000 laptop in December specifically for the deduction, check that rule before assuming you get the full amount this year.
Work out what yours are worth
The business expense calculator takes a purchase and a business-use percentage and tells you what it actually costs you after tax — including the self-employment tax saving most calculators leave out.
