The Self-Employed Tax Deduction Checklist: 40+ Write-Offs You Might Be Missing (2026)

By TraxGig Team · July 1, 2026 · 13 min read

Every deduction you miss is money handed to the IRS that you were never required to give. Because your taxes are based on net profit, not gross income, each legitimate write-off directly shrinks your tax bill — often by 15–30 cents on the dollar. The problem is that most self-employed people only remember the obvious ones. This is a complete, categorized checklist of the deductions available to freelancers, gig workers, and small business owners — including the ones people most often forget.

The golden rule for every item below: an expense is deductible if it is ordinary and necessary for your business. If something is used for both business and personal life, you deduct only the business-use percentage — not the whole thing.

Your workspace

Home office. A space used regularly and exclusively for work lets you deduct a share of rent/mortgage, utilities, and insurance — one of the largest deductions available to solo workers.
Rented office or studio space and coworking memberships.
Utilities for a dedicated business space — electric, gas, water, trash.
Internet and phone — the business-use portion of your monthly bills.

Vehicle and travel

Business mileage at the IRS standard rate, or actual vehicle expenses (gas, maintenance, insurance, depreciation) — you pick the method that saves more.
Parking and tolls incurred for business.
Business travel — flights, hotels, rental cars, and transportation for work trips.
50% of business meals — meals with clients, or while traveling for work.

Equipment and supplies

Computers, phones, cameras, and tools. Larger items can often be fully deducted the year you buy them under Section 179 rather than depreciated.
Office furniture — desks, chairs, shelving, lighting.
Supplies and materials consumed in your work.
Repairs and maintenance on business equipment.

Software, subscriptions, and services

Software and apps — design tools, editing suites, accounting software, project management, cloud storage, AI tools.
Website costs — hosting, domain, themes, plugins.
Professional subscriptions and trade publications.
Bank and merchant fees — business account fees, payment processing, platform commissions, PayPal/Stripe cuts.

People you pay

Contractors and freelancers you hire — editors, designers, virtual assistants, subcontractors.
Professional services — accountants, bookkeepers, lawyers, consultants.
Wages to employees, including reasonable wages paid to your own children for genuine work.

Insurance and health

Self-employed health insurance premiums for you and your family — a major above-the-line deduction.
Business insurance— liability, professional/E&O, equipment coverage.
HSA contributions if you have a qualifying high-deductible health plan.

Growth, marketing, and education

Advertising and marketing — online ads, business cards, printing, promotional samples, directory listings.
Education that maintains or improves your skills — courses, certifications, workshops, books.
Conferences and industry events, including the travel to attend them.
Professional dues and memberships.

The deductions people most often forget

These are legitimate and common, yet routinely left off returns:

Deduction	Why it's missed
Half of self-employment tax	It's automatic on the return but people forget it exists
Retirement contributions (SEP/Solo 401k)	Seen as saving, not as a deduction
Startup costs	Expenses before you launched can often be deducted
Business use of a personal phone	People deduct $0 instead of the business %
Bank and payment processing fees	Small amounts that add up to hundreds
Mileage to the bank, post office, suppliers	Short local trips feel too minor to log
Software free trials that converted to paid	Easy to lose track of small recurring charges
Interest on business loans or credit cards	Business-portion interest is deductible

Retirement: a deduction that pays you

Contributions to a SEP IRA or Solo 401(k) reduce your taxable income now while building your own retirement. It is one of the few deductions where the money stays yours — you're moving it from "taxable income" into "your future," not spending it. For higher earners, this can be the single largest deduction on the return.

What you cannot deduct

Knowing the limits keeps you out of trouble:

Everyday clothing, even if you wear it to work (unless it's a genuine uniform not suitable for everyday wear).
Personal meals and groceries.
Commuting from home to a regular workplace.
The personal-use share of anything mixed-use — a phone, car, or internet used for both.
Fines and penalties.

Recordkeeping: the habit that makes it all real

A deduction you can't substantiate is a deduction you can't safely take. You don't need to be perfect, but you do need a system:

Keep receipts — a photo of each one is enough for most purposes.
Use a dedicated business bank account and card so business and personal never mix.
Log expenses as they happen, not in a panic every April.
Note the business purpose for anything that could look personal.
Keep records for at least several years in case of questions.

The bottom line

The self-employed people who keep the most aren't the ones with secret loopholes — they're the ones who track ordinary expenses consistently and remember the categories everyone else forgets: half their self-employment tax, retirement contributions, home office, the business share of their phone, and every small fee. Work through this checklist once, build the tracking habit, and you'll stop overpaying for good.
