Coinbase CEO Brian Armstrong and Chief Policy Officer Faryar Shirzad have issued strong public denials against allegations that the cryptocurrency exchange is lobbying against a proposed de minimis tax exemption for Bitcoin. The controversy erupted on social media platform X on March 11, 2026, with claims suggesting Coinbase was privately telling Washington lawmakers the exemption was unnecessary and "dead on arrival" to protect its lucrative stablecoin business.
The proposed exemption is considered crucial for Bitcoin's adoption as a medium of exchange, as it would eliminate capital gains taxes and IRS reporting requirements on small, everyday cryptocurrency transactions, such as buying coffee. Critics alleged that Coinbase, which has a significant financial stake in its USD Coin (USDC) stablecoin, was pushing for the exemption to apply only to regulated, dollar-pegged stablecoins like USDC, not Bitcoin.
This speculation gained traction due to Coinbase's substantial revenue from its stablecoin operations. In 2025, the company generated an estimated $1.35 billion in stablecoin revenue, a 48% year-over-year increase, primarily from interest earned on U.S. Treasuries held in the USDC reserve pool. Following the passage of the GENIUS Act in July 2025, some analysts projected this revenue could surge up to 7x with broader USDC adoption in payments.
In response, Armstrong labeled the claims "misinformation" and a "total lie." He stated on X, "I've spent a bunch of time lobbying for Bitcoin's de minimis tax exemption, and will continue doing so. It's obviously the right thing." Shirzad echoed this sentiment. The issue drew in Jack Dorsey, a prominent Bitcoin maximalist, who publicly questioned Armstrong on the platform. Armstrong confirmed Coinbase's support for the Bitcoin exemption, replying "Yep" to Dorsey's inquiry.
