(Bloomberg) -- The Senate’s bipartisan infrastructure deal envisions imposing stricter rules on cryptocurrency investors to collect more taxes to fund a portion of the $550 billion investment into transportation and power systems.

The provisions would raise an additional $28 billion from cryptocurrency transactions, according to a summary of the plan. The proposal would impose more rules on crypto brokers to report transactions of digital assets, including virtual currencies, to the Internal Revenue Service. It would also require businesses to report crypto transactions of more than $10,000.

The cryptocurrency measures were last-minute additions to the infrastructure deal announced Wednesday after weeks of haggling between Republicans and Democrats over what spending to include in the deal and how to pay for it. Imposing more scrutiny on cryptocurrency trades has been a priority for members of both parties, including President Joe Biden’s Treasury Department, and Senator Rob Portman of Ohio, the lead Republican in the infrastructure talks.

The Treasury, in a May report on tax-enforcement proposals, said that additional measures on crypto assets are necessary “to minimize the incentives and opportunity to shift income out of the new information reporting regime.” Cash transactions in excess of $10,000 are already subject to IRS reporting requirements.

The proposal comes as IRS enforcement officials say that cyptocurrency is increasingly becoming an area for tax cheats to hide income from the federal government. The IRS in 2020 added a line about cryptocurrency on Form 1040, the individual tax return, in an effort to gain more visibility into virtual currency transactions.
