Electronic filing method for Form 1099-K
For the 2020, 2021, 2022, and 2023 reporting periods, you are required to submit Forms 1099-K issued to a payee with an Illinois address electronically if:
- you are required by the IRS to electronically file Forms 1099-K; or
- the payee has four or more separate transactions, and the cumulative total exceeds $1,000.
Note: For reporting periods beginning on or after January 1, 2022, the American Rescue Plan Act of 2021, Public Law 117-2, reduced the reporting amount for Form 1099-K to $600 with no minimum number of transactions. However, according to IRS Notice 2023-10, issued December 23, 2022, the IRS is postponing implementation of the $600 reporting threshold for reporting periods beginning on January 1, 2022.
Following feedback from taxpayers, tax professionals and payment processors and to reduce taxpayer confusion, the Internal Revenue Service released Notice 2023-74 announcing a delay of the new $600 Form 1099-K reporting threshold for third party settlement organizations for calendar year 2023. As the IRS continues to work to implement the new law, the agency will treat 2023 as an additional transition year. Given the complexity of the new provision, the large number of individual taxpayers affected and the need for stakeholders to have certainty with enough lead time, the IRS is planning for a threshold of $5,000 for tax year 2024 as part of a phase-in to implement the $600 reporting threshold enacted under the American Rescue Plan (ARP).
All other Forms 1099 are not included in the electronic filing mandate or are not required to be submitted to Illinois unless we request them. The Illinois Department of Revenue does not accept Forms 1099-K submitted by mail if you are mandated to electronically submit them. Currently, issuers of Form 1099-K can electronically submit them using the following methods:
