Tax season for solo Gumroad sellers usually means exporting two CSVs, guessing at net profit, and hoping your accountant can untangle platform fees from gross revenue.
SellerLedger on Gumroad ($17) ships a Tax-Prep Summary Sheet tab aligned with US Schedule C lines — gross receipts, total expenses, net profit — plus a quarterly set-aside estimator. Same module is listed under WHAT'S INSIDE on their checkout.
US sellers only. Schedule C categories as of 2026. Data organizer for your accountant — not tax advice.
What Schedule C lines you actually need from CSV exports
For most solo digital sellers, three numbers matter before you open TurboTax:
| Schedule C line | What it maps to |
|---|---|
| Line 1 Gross receipts/sales | Product revenue from Gumroad + Stripe |
| Line 28 Total expenses | Platform fees, ad spend, software (we start with fees) |
| Line 31 Net profit (loss) | What you actually kept after fees and refunds |
Orion's sheet calculates these inside Google Sheets. Our clone prints them to stdout after one CLI run:
python3 seller_ledger.py gumroad-sample.csv stripe-sample.csv -o ledger.csv --tax-rate 0.28
Example output (sample data):
--- Tax-prep summary (US Schedule C organizer, 2026) ---
Line 1 Gross receipts/sales: 131.00
Line 28 Total expenses: 7.08
Line 31 Net profit (loss): 104.92
Plus gross revenue, platform fees, net profit, and a quarterly set-aside estimate at your --tax-rate.
