US Lawmakers Advance Crypto Tax Bills Targeting Staking, Wash Sales, Stablecoins

US lawmakers are moving to close long-standing gaps in cryptocurrency taxation, a shift that could materially change how staking rewards, mining income, stablecoin transactions, and ‘wash sale’ loss-harvesting are treated under federal law. The effort signals a broader pivot from IRS-driven guidance toward clearer, statute-based rules—an evolution that market participants say is necessary for the sector to mature in the world’s largest capital market.

According to research from MEXC Ventures, the House Ways and Means Committee—the primary venue for US tax legislation—is set to unveil a package of seven crypto tax bills on June 5, 2026. That timing corresponds to Thursday in the US (ET), following reporting that the initiative is being advanced under the leadership of Committee Chair Jason Smith. If introduced as described, the package would attempt to codify definitions and tax triggers that have often been left to a mix of IRS notices, administrative interpretation, and tax court decisions.

At the center of the debate is the taxation of staking rewards, a contentious topic since proof-of-stake networks such as Ethereum (ETH) became mainstream. The unresolved question has been whether rewards should be treated as taxable income when received—or only when the tokens are sold. Taxation at receipt can create ‘liquidity risk’ by imposing obligations before an investor has realized cash proceeds, while taxation at sale can function as de facto deferral. MEXC Ventures argued the forthcoming bills represent one of the first attempts to address this issue directly in written law rather than through incremental agency interpretation.

Another major flashpoint is whether the ‘wash sale’ rule—already applied to stocks and bonds—should be extended to digital assets. Under current US law, investors in many traditional securities cannot claim a tax loss if they repurchase the same or substantially identical asset within a short window. Crypto has largely existed outside a clearly defined wash sale framework, enabling some investors to sell Bitcoin (BTC) or Ethereum (ETH) at a loss near year-end and repurchase quickly to preserve market exposure while booking the loss. A statutory expansion could align crypto tax treatment more closely with conventional markets, potentially reshaping common loss-harvesting tactics and tightening compliance expectations for both retail and institutional traders.

Mining income is also expected to feature prominently. Key questions include how mining rewards should be valued—particularly when token prices are volatile—and what expenses can be deducted, from equipment depreciation to electricity and operating costs. With prior practice heavily influenced by administrative guidance and individualized interpretations, miners in the US have faced uncertainty in accounting and reporting. Industry observers view clearer rules as consequential for competitiveness, especially at a time when mining margins are sensitive to energy prices, network difficulty, and broader market cycles.

The package may also include a targeted exemption designed to make stablecoins more practical for everyday use. In the current framework, using stablecoins to purchase goods or swap into other assets can still generate a taxable event, creating paperwork burdens disproportionate to the economic gain—particularly for small transactions. If lawmakers adopt a limited exclusion for certain stablecoin activity, it could be interpreted as policy support for stablecoins as ‘payment infrastructure’ rather than purely speculative instruments, potentially accelerating adoption in commerce and fintech rails.

The tax initiative is unfolding alongside a widening set of digital asset policy discussions in Washington. MEXC Ventures noted the committee has been coordinating with the Treasury Department and is likely to solicit input from industry and tax experts during hearings. In parallel, lawmakers are debating broader measures touching on market structure and oversight—such as the CLARITY Act—as well as stablecoin reserve requirements under the GENIUS legislation. Taken together, these tracks suggest the US is moving toward a more comprehensive framework spanning taxation, market plumbing, and prudential standards.

For institutional investors, the stakes extend beyond marginal tax rates. Predictable rules are critical to estimating ‘compliance costs’, designing internal controls, and aligning accounting policy with risk management. Market participants often argue that ambiguity can be more prohibitive than the tax burden itself, because uncertainty widens the range of potential liabilities and enforcement outcomes. Clear statutory language—if enacted—could reduce the perceived regulatory overhang and support deeper participation by funds, corporates, and traditional financial intermediaries.

Still, substantial hurdles remain before any proposal becomes law. The bills would need to clear committee review, hearings, and House votes, and ultimately require consensus through the broader legislative process—where provisions may be revised, narrowed, or expanded. Definitions and scope will be especially sensitive, given diverging incentives across staking platforms, miners, exchanges, DeFi users, and stablecoin issuers.

MEXC Ventures said that if the seven-bill package passes, the US crypto tax regime could move away from a ‘patchwork’ of guidance toward a more consistent legislative foundation. Markets will be watching whether the proposals reduce uncertainty around staking, mining, stablecoin usage, and loss treatment—changes that could influence where companies build, how investors structure exposure, and how quickly digital assets integrate into the mainstream financial system.
