If you determine your online sales are an activity you have engaged in for profit, as an Online Auction Seller you are considered a self-employed taxpayer and must file Schedule C (Form 1040) Profit or Loss From Business. In this situation, you must report all your business income from these sales. Additionally, you may be able to claim a deduction for certain business expenses. If your net profit is above $400, you will be subject to self-employment taxes in addition to individual income taxes.

Due to the increasing volume of online sales, effective calendar years beginning after December 31, 2010, Form 1099-K Payment Card and Third Party Network Transactions must be issued by the Payment Settlement Entity (PSE) to the payee to report payments made in settlement of reportable payment transactions. Similar to a Form W-2 or 1099-MISC, this form will be issued to the taxpayer and the IRS by the issuer.

Per IRS Instructions for Form 1099-K, on page 3:

Who Must File.

Every PSE or other party which submits instructions to transfer funds to the account of a participating payee, in settlement of reportable payment transactions, must file an information return (Form 1099-K) with respect to each participating payee for that calendar year.

Please see the Form 1099-K instructions for an overview of the exceptions.

Note. If a PSE contracts with an electronic payment facilitator (EPF) or other third-party payer (TPP) to make payments in settlement of reportable payment transactions on behalf of the PSE, the facilitator or other third party must file Form 1099-K in lieu of the PSE.

To enter a Form 1099-K for Schedules C, E, or F, go to our Form 1099-K - Entering in Program FAQ.
