The US Treasury Wants $10K+ Crypto Transfers to Be Reported to the IRS The government is concerned about tax evasion via digital currencies.

Cryptocurrencies pose "a significant detection problem by facilitating illegal activity" such as tax evasion, according to the U.S. Treasury, which says any transfer up to $10K should be filed with the IRS.

The IRS has already started tracking taxpayers who own cryptocurrencies and can legally seize assets of tax evaders.

The Treasury's proposal is also part of Biden's comprehensive tax compliance plan, which aims to close the gap between taxes paid and taxes owed. That difference, which totaled $600 billion in 2019, could balloon to $7 trillion if not addressed.
