Schedule C deductions — the full list

Why Schedule C deductions matter more

A $1,000 personal itemized deduction saves you ~$220 (22% bracket). The same $1,000 as a Schedule C deduction saves you $220 in income tax plus $153 in self-employment tax — $373 total. That's why tracking business expenses religiously is the single highest-leverage thing a freelancer can do.

Deductions by Schedule C line

A worked example: $90,000 freelancer

Here's what a typical solo consultant's Schedule C looks like — and what the deductions are actually worth at a 22% federal bracket plus 15.3% self-employment tax (37.3% combined on every deducted dollar).

Estimates for illustration — your bracket, state tax and deduction phase-outs change the numbers. Run yours with the tax estimator.

Home office: simplified vs actual

Either way the space must be used regularly and exclusively for business. A desk in the corner of a bedroom qualifies; the kitchen table you also eat dinner at does not.

Mileage: standard rate vs actual expenses

The standard rate (70¢/mile for 2026 business miles) bundles gas, insurance, maintenance and depreciation into one number — you just log miles. Actual expenses means tracking every vehicle cost and deducting your business-use percentage, which usually wins for expensive vehicles driven few miles. Key rule: if you want to use the standard rate on a car, you must choose it the first year you use that vehicle for business.

• Commuting from home to a regular office is never deductible.
• If your home is your principal place of business, trips to clients count from your front door.
• A contemporaneous log (date, miles, purpose) is what survives an audit — reconstructing in April does not.

Deductions people miss

• Business portion of tax prep — see our tax prep deductibility guide.
• Payment processing fees — Stripe/PayPal/Square fees (Line 27a).
• Bank fees — monthly maintenance, wire fees on your business account.
• Software you already pay for — Adobe, Notion, Zoom, ChatGPT Plus if used for work.
• Continuing education — courses, books, conferences to maintain or improve current skills.
• Startup costs — up to $5,000 of pre-launch expenses deductible in year one, the rest amortized over 15 years.
• Business gifts — $25 per recipient per year (low, but real).
• Health insurance premiums — not on Schedule C, but on Schedule 1 as an adjustment (self-employed health insurance).
• Half of SE tax — automatic adjustment on Schedule 1, not a Schedule C deduction, but worth knowing.

What raises audit risk (and how to stay clean)

• 100% vehicle business use. Almost nobody has a car used only for work. Claim an honest percentage.
• Round numbers everywhere. "$5,000 supplies, $3,000 travel" reads as estimates, not records.
• Losses year after year. Three-plus loss years invites the hobby-loss question. Document your profit motive.
• Outsized meals and travel relative to revenue. Note who you met and why on each receipt.
• Personal spending in the business account. The fastest way to lose an audit is commingled books.

Recordkeeping that survives an audit

Keep records for three years after filing (seven for property, equipment depreciation and bad debts). A digital photo of a receipt is fully acceptable to the IRS — paper is not required. For each expense you want the amount, date, vendor, and business purpose.

How to track them without losing your mind

1. Use one card for business only.
2. Auto-import transactions into accounting software.
3. Snap receipts the day you get them — AI OCR maps to Schedule C lines automatically.
4. Reconcile 15 minutes a week instead of 15 hours in April.
5. At tax time, export the Schedule C report and hand it to your CPA or tax software.
