The "Providing Analogous Rules for Digital Assets Act," or PAR Act, aims to clarify the tax treatment of digital assets by amending the Internal Revenue Code of 1986. It integrates digital assets into existing tax frameworks, ensuring consistency with how traditional financial instruments are treated, and provides comprehensive definitions for various digital asset types. One key provision amends Section 1058, extending rules for transfers of securities under lending agreements to include "specified assets," which now explicitly encompasses traded digital assets . This ensures transferors in such agreements receive equivalent payments for distributions and assume obligations, mirroring the treatment of securities lending, effective for transfers after enactment. The bill also modifies Section 475 to allow dealers and traders of covered digital assets to elect mark-to-market accounting. Covered digital assets include widely traded digital assets, related notional principal contracts, derivative instruments, and hedges, with a special rule preventing dual classification as securities or commodities under other parts of Section 475. This election provides a standardized accounting method, with a 4-year spread for adjustments. Additionally, the Act establishes a digital asset trading safe harbor by amending Section 864(b)(2). This clarifies that trading in traded digital assets through a resident agent or for a taxpayer's own account (excluding dealers) will not constitute engaging in a U.S. trade or business for foreign persons, applying to taxable years beginning after December 31, 2025. This aims to reduce tax barriers for international participation. Crucially, the bill introduces extensive definitions for digital asset terms into Section 7701, including: Digital asset : A digital representation of value on a cryptographically secured distributed ledger. Traded digital asset : A fungible digital asset with readily available quotations, not a tokenized asset, or a wrapped asset with a traded reference asset. Widely traded digital asset : A traded digital asset meeting specific criteria like market capitalization over $500 million and consistent quotation availability. Tokenized digital asset : A digital asset whose value is significantly tied to something other than the ledger's operation, excluding qualified U.S. dollar stablecoins. Wrapped digital asset : Redeemable one-for-one for another digital asset but recorded on a different ledger. Qualified U.S. dollar stablecoin : Defined by reference to the GENIUS Act, with the Secretary having authority to treat them as dollars. Finally, the bill includes rules of construction, explicitly stating it does not create an inference about whether a digital asset constitutes a security or commodity for other laws, nor about the proper application of tax law to periods before the Act's effective dates.
