Small Business Expense Categories: A Schedule C Cheat Sheet
Most small-business owners overpay on taxes for one boring reason: they don’t categorize expenses as they go, so deductions slip through the cracks. The fix is a simple habit — tag every cost with the right small business expense category the moment you record it. This cheat sheet maps the everyday costs you actually have to the standard IRS Schedule C lines, in plain English.
(Schedule C is the form US sole proprietors and single-member LLCs use to report business profit or loss.)
The core Schedule C categories
These cover the vast majority of what a small business spends:
- Advertising — Etsy/Facebook/Pinterest ads, business cards, promotional samples, sponsored posts.
- Car & truck expenses — business mileage at the IRS standard rate, or actual vehicle costs. Track the miles either way.
- Commissions & fees — marketplace fees (Etsy, eBay), payment processing (Stripe, PayPal, Square), affiliate payouts.
- Contract labor — payments to freelancers or subcontractors (issue 1099s where required).
- Supplies — materials consumed making your product or delivering your service.
- Office expense — printer ink, paper, small office items, postage for admin.
- Rent or lease — studio, booth, storage, or equipment rental.
- Software & subscriptions — design tools, accounting apps, website hosting, this spreadsheet. (Often listed under “Other expenses.”)
- Shipping & postage — labels, boxes, mailers, packing materials.
- Travel & meals — business trips (travel is generally fully deductible; meals typically 50%).
- Utilities & phone — the business-use portion.
- Home office — a portion of rent/mortgage, utilities and internet if you have a dedicated space (there’s also a simplified square-footage method).
The categories people forget
These are legitimate and commonly missed:
- Bank & merchant fees — monthly account fees, chargeback fees, currency-conversion fees.
- Education — courses, books and workshops that maintain or improve your business skills.
- Professional services — bookkeeper, accountant, lawyer, designer.
- Insurance — business liability or product insurance.
- Startup costs — certain costs before you opened, handled specially in year one.
Three rules that keep it clean
- Tag as you go, not at tax time. A category chosen in the moment (when you remember what the charge was) beats guessing from a bank statement months later.
- Keep business and personal separate. A dedicated card or account makes every transaction obviously deductible — or obviously not.
- Save the proof. A photo of the receipt attached to the row is enough for most purchases; note the business purpose for anything that could look personal.
Turn categories into a tax summary automatically
A category list only saves you money if it rolls up into a total per line. That’s the whole job of a good bookkeeping template: you tag each expense once, and it produces a category-by-category summary you can hand to your accountant or type straight onto Schedule C.
The Small Business Bookkeeping Spreadsheet builds these Schedule C-style categories in for you, with a deductible flag that instantly totals your write-offs, an automatic Profit & Loss dashboard, and mileage and sales-tax trackers — Google Sheets and Excel, light and dark.
