Illinois crypto tax challenge draws backing from Andreessen Horowitz, DeFi Education Fund
Crypto tax faces backlash

Illinois' planned tax on digital asset transactions is facing broader resistance from major crypto investors, developers and advocacy groups as the state's legal fight over the measure expands. A new amicus brief argues the law's scope is too wide and says it could affect an estimated 2.64 million Illinois residents who hold digital assets.

Highlights

  • Andreessen Horowitz, DeFi Education Fund, and industry peers filed an amicus brief opposing Illinois's Digital Asset Tax Act for targeting blockchain transactions.
  • The law sets a 0.2% tax on digital asset transactions, originally effective January 2027, now delayed to July 2027 under Illinois's fiscal year 2027 budget.
  • Legal opposition expands with entry of new crypto and VC groups as the industry seeks to block the tax before its planned rollout.

Industry brief targets tax scope

The Block reports the DeFi Education Fund, Paradigm, Uniswap and Andreessen Horowitz are leading a group that filed an amicus brief supporting the crypto industry's challenge to Illinois's Digital Asset Tax Act on Thursday.

The signatories also include Aave Labs, Aptos Labs, Aztec Labs, Chainlink Labs, Hyperliquid Policy Center, Jito Labs, Multicoin Capital Management LLC, Orca Creative, Solana Policy Institute and Stand With Crypto. In the filing, the group says the act singles out blockchain-based transactions for unfavorable tax treatment and unfairly targets the digital asset sector.

The brief says the law does not adequately account for the technological complexities of digital assets. It argues the act fails to draw clear enough boundaries between taxable digital asset business activity and the software and network infrastructure that allows users to transact independently.

Legal dispute widens before 2027 rollout

The amicus filing adds to a wider court fight over the Illinois measure after the Blockchain Association, the Crypto Council for Innovation and The Digital Chamber sued the state. Governor JB Pritzker signed the Digital Asset Tax Act into law as part of Illinois's fiscal year 2027 budget planning.

The law imposes a 0.2% tax on digital asset transactions. It was initially due to take effect in January 2027, but that timeline has since been pushed back to July 2027.

Crypto industry advocates have criticized the measure as unprecedented and are seeking to block its implementation before it comes into force. The latest filing shows opposition is widening across venture capital, protocol and policy groups as Illinois moves toward the delayed launch date.
