If you sell on eBay, Form 1099-K can be confusing. The gross amount reported is often much higher than what reached your bank account. If you do not track your deductions, you could pay tax on money you never kept.
Why this matters
1. Understand what eBay reports: gross, not net
The biggest surprise for new sellers is the 1099-K total. It reports gross payment volume, meaning amounts before fees. That can include:
- The item sale price
- Shipping charged to the buyer
- Fees eBay kept before paying you out
Shipping money you spent on labels and fees you never received still count toward that total. Record them as expenses on Schedule C so you are not taxed on them as profit.
2. The essential deductions checklist
To lower taxable income legally, track every deductible expense. Here is a starting checklist for eBay sellers:
Direct costs
- Cost of goods sold
- eBay final value fees
- Promoted listing fees
- Shipping labels
- Packaging materials such as boxes and tape
Indirect costs
- Home office, if you qualify
- Mileage for sourcing
- Storage units
- Software subscriptions
- The business share of phone and internet
3. How to track cost of goods sold
This is where many resellers go wrong. You generally cannot deduct the cost of inventory until you sell it.
Example
You need a system that links every sale to its specific purchase cost.
4. The manual way: spreadsheets
You can do this for free in Google Sheets or Excel. It takes discipline:
- 1
Export
Download your transaction report from eBay Seller Hub every month. - 2
Add costs
Enter the purchase price for every item sold. - 3
Categorize
Sort every expense into shipping, fees, and supplies. - 4
Total
Sum the totals for your Schedule C.

Past roughly 50 sales a month, spreadsheets become a part-time job. That is why we built Eclipse. With your bank connected through Plaid, and eBay as it rolls out to more accounts, Eclipse:
- Imports sales and fees from connected channels
- Matches payouts to bank deposits
- Tracks inventory and calculates cost of goods sold

Common mistakes to avoid
- Deducting inventory you have not sold. Only deduct cost of goods for items that sold in the tax year. Unsold inventory is an asset.
- Ignoring small expenses. A $5 roll of tape and a $12 monthly subscription add up. Bank sync catches them as they happen.
- Mixing personal and business. A separate business checking account makes records much easier to defend.
