The American Rescue Plan of 2021 changed the reporting threshold for TPSOs. The new threshold for business transactions is $600 per year; changed from the previous threshold of more than 200 transactions per year, exceeding an aggregate amount of $20,000.

The transition period described in Notice 2023-10 (PDF), delays the reporting of transactions in excess of $600 to transactions that occur after calendar year 2022.
