Expense Categories for Online Business Owners (Etsy, Shopify & Digital Sellers)

Here's what changes once you know your deductions cold: the receipts stop feeling like a threat. Every Etsy transaction fee, every packaging run to Uline, every Canva subscription — they're not costs to dread at tax time. They're offsets you've already captured. That's the shift from running a business blind to running it knowing exactly what's going on.

The expense categories for online business owners — whether you're selling handmade goods on Etsy, running a Shopify store, or selling digital products on Gumroad — all live on Schedule C of your federal return. The 14 categories below map directly to Schedule C lines, which means every dollar tracked flows into the right bucket automatically. No re-sorting at year-end.

Platform & Marketplace Fees — Schedule C: Line 10

Every fee Etsy, Shopify, Amazon, Printify, or Gumroad charges — listing fees, transaction percentages, monthly plan costs. For most Etsy sellers this is one of the top three recurring costs, and easy to undercount without pulling monthly settlement statements. Watch for Etsy's monthly statement: it bundles transaction fees and listing fees into a single charge. Split into separate entries if you want the detail; log the total if you don't.

Payment Processing Fees — Schedule C: Line 10

Stripe, PayPal, Square, and Venmo Business all charge a percentage per transaction. These fees arrive quietly — often bundled into payout summaries — but they add up fast on high-volume months. Stripe fees alone can run 2–3% of gross revenue. Log each source as its own entry so you can see where fee friction is highest. Keep these separate from platform fees — they're both Line 10, but the split matters when you're scaling.

Shipping & Postage — Schedule C: Line 27a

Pirateship, Shippo, USPS Click-N-Ship, UPS, FedEx — anything paid to get product to customers. Log it at purchase, not when the package ships — the charge hits your account when you buy the label. Physical goods sellers should expect this to be one of their largest monthly categories, especially during Q4.

Packaging & Supplies — Schedule C: Line 22

Poly mailers, boxes, tissue paper, bubble wrap, tape, bags, packing peanuts. Uline is the most common merchant. The watch-out: do not mix Raw Materials and Packaging into the same entry. If a single Uline order includes both packaging and supplies that touch the product itself, split it — they're on different Schedule C lines.

Raw Materials — Cost of Goods Sold (COGS)

The supplies you turn into product: fabric, yarn, resin, wood, coffee beans, candle wax, ceramics. Michaels, Hobby Lobby, Joann, and wholesale suppliers are typical merchants. Raw materials land in COGS rather than a standard expense line — which is why they have their own category, kept separate from packaging. Mixed Amazon orders (raw materials + office supplies + personal) should be split by line item. This is the most common source of mis-categorization for physical goods sellers.

Software & Subscriptions — Schedule C: Line 18

The tools that run the business: Canva, Adobe, Mailchimp, ConvertKit, Squarespace, Later, Planoly, Notion, Google Workspace, Zoom, QuickBooks. Digital and print-on-demand sellers often find this is their largest recurring cost category — the monthly software stack can reach $100–200 before you notice. Log each subscription separately so you can see the full recurring cost picture. Annual renewals should be logged as a single entry on the charge date, not divided across months.

Marketing & Advertising — Schedule C: Line 8

Meta Ads, Pinterest Ads, Etsy Promoted Listings, Google Ads. Log each campaign spend when it clears your card. If you run seasonal campaigns — Valentine's Day, holiday, spring launch — this category shows you exactly what each campaign cost and how spending shifted through the year. Deductible in full as an ordinary business expense.

Equipment & Electronics — Schedule C: Line 13

Business-use technology: laptop, iPad, Cricut, label printer, camera, shipping scale, ring light, external drives. Log at purchase. Equipment over $2,500 may need to be depreciated rather than expensed in full — ask a CPA before assuming it's a single-year deduction. Expense Ledger captures the spend; the CPA handles the depreciation election.

Phone & Internet — Schedule C: Line 25

Monthly phone and internet bills — the business-use percentage. Log the full bill amount; your accountant or your own records will determine the business-use percentage when you file. Keeping full amounts is cleaner than calculating the split every month. A dedicated business phone or internet line is fully deductible.

Home Office — Schedule C: Line 30

Printer paper, ink cartridges, desk supplies, small furniture used for business. The home office deduction itself is calculated separately (square footage of dedicated space as a percentage of your home), but the supply spend captured here feeds the broader picture. Staples, Office Depot, Amazon are typical merchants.

Education & Training — Schedule C: Line 27a

Skillshare, Udemy, Masterclass, workshop fees, books, coaching, conferences — any learning directly related to your business. Log annual memberships at the charge date, not spread across months. Books from Amazon are common here — if an Amazon order mixes business books with personal items, split the entry.

Professional Services — Schedule C: Line 17

Your CPA, bookkeeper, business attorney, Fiverr or Upwork contractors, graphic designers, consultants. Log at invoice payment, not when the work was done. This is also where tax preparation fees land — the cost of filing is itself deductible.

Vehicle & Mileage — Schedule C: Line 9

Supply runs to Michaels, post office trips, trips to the UPS Store — every mile driven for business purposes is deductible at the IRS standard rate. At current rates, 15,000 business miles in a year produces a significant deduction just from the driving. Track every trip in the moment; reconstructing job site addresses from calendar entries in March is painful.

Expense & Mileage Ledger and Expense & Mileage Ledger + Reporting include a dedicated Mileage Log and Mileage Form — log trips from your phone as you go, destination, purpose, and miles all captured while the drive is fresh.

Banking & Merchant Fees — Schedule C: Line 27a

Monthly account maintenance fees, wire fees, and other bank charges on business accounts. Chase Business Checking, PayPal monthly fees, Square account fees. Keep these separate from Payment Processing Fees — bank account fees are a distinct Line 27a item from transaction-level processing charges.

Common mistakes to watch for

Three categories trip up online sellers more than any others.

Raw Materials vs. Packaging. The most frequent mis-categorization for physical goods sellers. Raw materials become part of your product; packaging holds the product after it's made. They're on different Schedule C lines. The test: did this item touch the finished product, or did it wrap it for shipping?

Platform fees vs. Payment processing fees. Etsy's transaction fee and Stripe's processing fee look similar but come from two different sources. Keep them in separate categories — they're both Line 10, but the split gives you clarity on where your fee burden sits.

Mixed Amazon orders. Amazon orders often span categories: raw materials, packaging, office supplies, and personal items in a single charge. Don't log the total as one entry. Split by line item into the correct categories.

Categories already built — no setup required

Expense Ledger comes with all 14 of these categories pre-built. The Expense Form presents them in a dropdown — log the amount, pick the category, attach a receipt photo if you have one. The Tax Summary tab totals everything by Schedule C line automatically. By the time tax season arrives, the records are already organized the way a return requires.

One purchase, no subscription, works in Google Sheets.

If you also track mileage, Expense & Mileage Ledger and Expense & Mileage Ledger + Reporting include a connected Mileage Log and Mileage Form. If you need to hand your accountant everything in one click, Expense & Mileage Ledger + Reporting includes the Email Tax Report — it sends your Tax Summary, full transaction list, and mileage log as formatted PDFs directly to your accountant, no spreadsheet access required. Tab Export lets you save any individual tab to Google Drive as a PDF if you need a single view mid-year.
