HB 645-FN establishes decentralized autonomous organizations (DAOs) as legal entities within the state of New Hampshire. The bill specifies that a DAO is a legal entity with limited liability and legal personality, and it outlines the requirements and provisions for DAOs. The bill also addresses issues such as fiduciary duties, contentious forks in the underlying blockchain, DAO restructuring, failure events, and taxation of DAOs. The bill does not have a fiscal impact on the state, county, or local level, but it may result in a loss of general fund revenues from annual report filing fees for the Department of State. The Department of Revenue Administration is unable to estimate the fiscal impact of the bill due to a lack of data on income generated from DAOs and how members of DAOs would be taxed in New Hampshire. The Department of Justice indicates that it could investigate and bring actions against DAOs, but the impact on the number of investigations or prosecutions is uncertain.
