Senate Republicans introduced the ADAPT Act on September 30, a 56-page bill that aims to rewrite how the U.S. tax code treats digital assets. The full name is the Aligning Digital Assets with Principles of Taxation Act, and it was introduced by Senator Steve Daines of Montana, a member of the Senate Finance Committee. He was joined by three Republican cosponsors: Senators Tim Scott, Cynthia Lummis, and Bernie Moreno.

The core problem the bill addresses is straightforward. Most U.S. tax regulations were written before blockchain technology existed, and they do not clearly cover every kind of digital-asset transaction. As a result, everyday actions like paying a network fee or spending stablecoins can trigger complex tax calculations that were never designed for those use cases. The ADAPT Act tries to fill those gaps with rules built specifically for crypto, rather than forcing digital assets into frameworks meant for traditional property and securities.

The most significant provision concerns stablecoin payments. Under the proposal, consumers who use qualifying U.S. dollar stablecoins to buy goods and services would generally not have to recognize a gain or loss on the transaction. The exemption is not a blanket tax exclusion for stablecoin activity. It applies to purchases of products and services, not to investment sales or exchanges, and it comes with conditions. The token must be issued by a permitted issuer under the GENIUS Act and appear on a Treasury list of stablecoins that traded within 3% of $1 over the preceding 12 months. The taxpayer must also have acquired the token within that price band. Traders, brokers, and dealers are excluded from the relief.

The bill also addresses one of the most persistent annoyances in crypto tax compliance: small network fees. Under current rules, paying a gas fee in crypto is itself a disposal that can require a separate gain-or-loss calculation. The ADAPT Act would exempt digital assets used to pay qualifying network fees, transaction fees, or gas fees of $10 or less. Costs belonging to the same economic transaction would be added together. The relief still requires adjusting transaction costs used to calculate gains, deductions, or an acquired asset's tax basis for the portion of the gain or loss that remains unrecognized. Professional traders, brokers, dealers, and anyone who initiated more than 5,000 digital asset transactions in the preceding tax year are excluded from this benefit as well.

For investors, the trade-off is tighter limits on a practice that has been widely used in crypto but unavailable in traditional markets. The bill would extend wash-sale rules to traded digital assets. Under these rules, a loss deduction is generally denied when an investor buys substantially identical assets within 30 days before or after a sale. Economically equivalent tokenized and bridged assets would count, which limits the ability to maintain the same exposure through another token. Qualified dollar stablecoins and acquisitions through staking or mining are among the exceptions, and assets acquired before enactment would be protected.

The bill also extends constructive-sale rules to crypto positions whose gains are locked in through offsetting trades. This would require investors to recognize gains when they effectively cash out through offsetting positions without selling their appreciated holdings. Qualified dollar stablecoins are excluded, and transactions entered into on or before enactment would be protected.

Staking and lending get targeted treatment as well. The bill would establish income-sourcing rules for staking and mining rewards, clarifying when those rewards are taxed and where that income is sourced. For lending, it would extend the existing non-recognition treatment for securities lending to qualifying digital asset lending arrangements. Eligible digital asset dealers and traders would be allowed to elect mark-to-market accounting.

The bill also addresses foreign investors trading through U.S. intermediaries, providing a safe harbor modeled on existing securities and commodities rules. It eases charitable giving rules for widely traded digital assets, with reports indicating that no formal appraisal would be needed. And it defines and sorts different types of digital assets, which is a foundational step for any tax framework that treats them differently based on their characteristics.

Most provisions would apply to tax years beginning after December 31, 2026, or to transactions occurring after that date. The bill is a proposal, not law. It must move through the Senate Finance Committee and the full legislative process before it could become law. The House Ways and Means Committee advanced its own digital asset tax package in September, which means Congress would eventually need to reconcile overlapping proposals if both move forward.

The ADAPT Act is not a comprehensive market structure bill. It is a tax bill, and it is being pursued separately from the broader debate over how crypto markets should be regulated. What it does is take a set of practical problems that have made crypto tax compliance difficult and confusing, and it offers specific, narrowly tailored solutions. The stablecoin payment exemption, the small-fee carve-out, and the extension of wash-sale and constructive-sale rules all follow the same logic: apply familiar tax principles to digital assets where they fit, and create targeted rules for the things that are genuinely unique to blockchain transactions.
