What is the IRS mandate on form count for the electronic filing of W2?

The Taxpayer First Act of 2019, enacted July 1, 2019, authorized the Department of the Treasury and the IRS to issue regulations that reduce the 250-return requirement for 2023 tax returns. However, the e-file threshold for returns required to be filed in 2023 remains at 250. The e-file threshold of 10 is effective for returns required to be filed on or after January 1, 2024.
