The Treasury Department called Thursday for requiring all transfers of more than $10,000 worth of cryptocurrency to be reported to the Internal Revenue Service as part of the Biden administration’s proposals to boost tax compliance. The move is likely to spur opposition from crypto investors, who have exploded in numbers in the past few months.

“As with cash transactions, businesses that receive cryptoassets with a fair-market value of more than $10,000 would also be reported on,” the Treasury wrote in a report on tax compliance proposals released Thursday.
