House Bill No. introduced by C. Hinkle and others proposes the establishment of a program by the Montana Legislature to return excess revenue to resident income taxpayers. The bill includes provisions for the legislature to enact income tax refunds when the state has surplus revenue, allowing them to determine the criteria for triggering refunds, calculating refund amounts, setting eligibility requirements, and deciding on distribution methods.

Additionally, the bill outlines that it will be codified as part of Title 15 and specifies that it will take effect upon approval by the electorate. It mandates that the proposed act be submitted to qualified voters during the general election in November 2026, with a ballot that includes options for voters to express their support or opposition to the legislative referendum.
