One bill targets property tax rules for digital assets, another would stop cities and counties from taxing blockchain nodes, and a resolution seeks to adjust the state constitution. The proposed crypto tax changes would require voter approval at the November 2026 general election, while the node-related bill may advance solely through the legislature.
