Crypto: a16z and Uniswap team up against Illinois tax

a16z, Paradigm, Uniswap and the DeFi Education Fund have filed suit against Illinois over its 0.2% cryptocurrency transaction tax, with the levy's implementation now delayed until July 1, 2027. The challenge targets a tax that would apply to digital asset transfers in the state, pitting major venture and DeFi players against a novel state-level revenue mechanism. The delay gives the industry time to litigate before any collections begin. The case matters because it could set a precedent for how states tax on-chain activity, with other jurisdictions watching closely. What to watch next is whether the court grants relief before the 2027 effective date and whether other states follow Illinois with similar transaction taxes.
