Illinois Proposes Tax Rules for Crypto Transactions Starting 2027

The proposed tax applies to the total value of assets involved in covered transactions, rather than just the broker's service fee. For instance, a $10,000 transfer would incur a $20 charge, regardless of whether the user realized a profit or loss. While the tax captures most exchange activity, it differentiates between platforms based on how they handle fees. DeFi protocols are excluded if they do not collect service fees; however, platforms that charge protocol maintenance fees are classified as digital asset brokers, making their transactions taxable. Similarly, moving assets to self-custody wallets becomes a taxable event if the exchange charges a transfer fee.

Stablecoins are explicitly included as taxable assets, as regulators view them as investments rather than exempt digital representations. Conversely, NFTs and tokenized securities are excluded due to their distinct utility or nature as collectibles. The state is currently soliciting public feedback on these draft rules through October 30. Despite the January implementation timeline, the tax faces significant legal headwinds. Industry groups, including the Blockchain Association and the Crypto Council for Innovation, have filed lawsuits challenging the measure’s constitutionality and its compliance with the federal Internet Tax Freedom Act. While these legal battles proceed in Sangamon County, the state continues its administrative preparations, though the rules have not yet been formally filed with the Secretary of State.
