Start with what you sold
A used household item is different from inventory you bought to resell. For a personal item, compare the selling proceeds with your cost. Personal losses aren't deductible. Personal gains can be taxable. When some items sold at gains and others at losses, don't simply net everything together.
Match the form to the transactions
Download the marketplace transaction history. Match dates, refunds, fees, and sale amounts to receipts or other cost records. Keep a separate category for business sales. Gross payments on a form aren't automatically your taxable profit. The IRS provides reporting instructions for personal items sold at a loss.
If the form includes money that wasn't a sale
Check for gifts, shared-expense reimbursements, duplicate forms, or payments that belong to someone else. Contact the issuer for a correction and keep the correspondence. Don't ignore a tax form just because you disagree with it. If it isn't corrected, use the IRS instructions for reporting an erroneous form.
| Transaction | Federal treatment to check |
|---|---|
| Personal item sold below cost | No deductible personal loss; explain reported proceeds |
| Personal item sold above cost | Report taxable gain |
| Business sale | Report business income and eligible expenses |
| Gift or reimbursement | Not a goods-or-services sale; review errors |
Your records checklist
- Save the form and the transaction export.
- Find purchase records for personal items.
- Separate gains, personal losses, and business receipts.
- Request corrections from the issuer and keep copies.
Common questions
- Does the reporting threshold make smaller sales tax-free?
- No. A form-reporting threshold doesn't decide whether income is taxable.
- Can I deduct a loss on my used couch?
- A loss on personal-use property isn't deductible. Reporting proceeds correctly keeps them from being mistaken for taxable profit.
