The second front of the encryption bill has opened, with tax policies focusing on the controversy over deferring taxes on mining and staking profits

According to CoinDesk, major lobbying organizations in the U.S. cryptocurrency industry jointly sent a letter to the House Ways and Means Committee, urging the advancement of the "Tax Clarity for Mining and Staking Act," advocating for tax treatment options for cryptocurrency miners and staking income recipients. The bill was introduced by Republican Congressman Mike Carey, and its core content allows taxpayers to choose the timing of taxation when they receive new mining or staking assets—either paying taxes at the time the assets are generated or deferring taxes until the final sale.

Industry associations, including the Blockchain Association, Digital Chamber, and Crypto Council for Innovation, have expressed support, arguing that the current tax system may force users participating in network security maintenance to bear tax burdens before they have realized the assets. Supporters claim that the proposal does not provide "indefinite deferral," but rather avoids immediate taxation on income that has not yet realized liquidity, thereby alleviating cash flow pressure on miners and validators.

However, Democratic lawmakers and some external critics are concerned that this mechanism could be exploited by large mining companies for long-term tax deferral, especially in the context of some publicly listed or politically connected companies participating in mining operations, raising potential policy arbitrage disputes. Meanwhile, the industry's focus remains on the broader "Digital Asset Market Structure Act" (Clarity Act), but tax issues have become the second key battleground, expected to continue advancing in tandem with regulatory framework legislation in the coming weeks.
