Many sole-proprietor craft sellers use Schedule C to report business income or loss. The IRS says Schedule C is for a business operated or profession practiced as a sole proprietor.
If the activity is carried on for income or profit with continuity and regularity, start organizing records as a business. If you are unsure, ask a tax professional before filing.
Schedule C record map for craft sellers
| Record | Why it matters |
|---|---|
| Gross sales | Starting income record. |
| Returns and refunds | Reconciles sales. |
| COGS | Cost of products sold. |
| Marketplace fees | Business selling expense. |
| Shipping labels | Fulfillment cost. |
| Supplies and software | Business expenses. |
| Mileage and shows | Needs logs and receipts. |
What is the difference between COGS and expenses on Schedule C?
COGS is the cost of the products sold. Expenses are other costs of running the business. For a candle seller, wax used in sold candles belongs in product cost logic, while bookkeeping software is a business expense.
Do not throw every purchase into one bucket. Inventory and COGS need enough detail to explain what sold and what remains on hand.
COGS vs expenses
| Item | Usually track as |
|---|---|
| Wax used in sold candles | COGS. |
| Shipping labels | Shipping or fulfillment expense. |
| Etsy listing fees | Selling expense. |
| Bookkeeping app | Software expense. |
| Unopened material stock | Inventory until used or sold. |
What should craft sellers give a tax preparer?
Give the preparer totals and backup: sales by platform, refunds, fees, shipping, COGS, inventory value, expense categories, mileage, and copies of any tax forms.
The best handoff is a summary plus source files. Do not send a pile of screenshots and expect clean advice.
- Annual sales by channel.
- Refunds and returns.
- COGS and inventory records.
- Expense totals by category.
- 1099-K and other tax forms.
- Questions about gray areas.
