The Internal Revenue Service says it is expanding automated comparisons between taxpayer filings and third-party information returns such as Form 1099-K. As more payments move through payment apps, online marketplaces, and other third-party payment networks, the agency says matching systems will play a larger role in reviewing income tax filings during the 2025 filing season.
Form 1099-K is an information return that reports payments received for goods or services through payment cards and third-party settlement organizations, including payment processors and peer-to-peer payment platforms. These reportable payment transactions may come from online marketplace sales, freelance marketplaces, crowdfunding platforms, ride-hailing platforms, car sharing services, and auction sites.
Payment settlement entities and third-party payment processors file Federal Form 1099-K with both the taxpayer and the Internal Revenue Service. Taxpayers usually receive this tax document by January 31, and the reported totals may later be compared with figures reported on a federal return, such as Form 1040.
The form generally reports the gross payment amount processed through a payment card processor or third-party payment settlement organization. Because it reflects gross receipts rather than final taxable income, totals may include refunds, fees, gift cards, shipping charges, or cash-back incentives, all of which must be reconciled when preparing tax forms.
A wide range of digital services may generate Form 1099-K reporting. Online marketplaces such as Facebook Marketplace, freelance marketplace platforms, ride-hailing platforms, crowdfunding platforms, and auction sites may issue the form when payments are handled through a payment processor or merchant acquirer.
Users of peer-to-peer payment platforms, third-party apps, or peer-to-peer payment systems may receive multiple information returns if transactions pass through multiple third-party processors. Each Federal Form 1099-K reports the processed volume handled by a specific payment card processor or third-party payment settlement organization.
Compliance programs rely heavily on third-party information reporting. When information returns, and other tax forms reach the Internal Revenue Service, automated systems compare them with figures reported on a tax return, such as Form 1040 or another federal return.
Internal Revenue Code rules, such as IRC 6050W(e), define the reporting structure for third-party network transactions and payment card activity. These provisions require payment settlement entities and third-party payment processors to report certain reportable payment transactions that exceed the reporting threshold or federal threshold requirements.
Recent policy changes, including the American Rescue Plan Act, adjusted threshold amounts tied to third-party payment networks. Historically, reporting occurred when processed volume exceeded USD 20,000 and when a transaction count requirement was met, although transitional guidance has altered the dollar limit in recent filing seasons.
If automated matching finds differences between third-party records and a tax return, the agency may send a CP2000 notice proposing adjustments. The notice may involve discrepancies related to gross receipts, non-employee compensation, stock sale income, canceled debt, or other items reported on tax forms.
Taxpayers may need to verify how income appears on Schedule C (Form 1040), Schedule D (Form 1040), Schedule 1 (Form 1040), Schedule E, or Schedule F. Businesses filing Form 1120 or partnerships filing Form 1065 may also review Federal Form 1099-K records to confirm totals reported by third-party payment processors.
