HI SB778

Adds a requirement that taxpayers claiming general excise tax (GET) benefits must owe less than 50% of their total GET liability for the taxable year.

Defines "reasonable cause" for waiving denial of GET benefits to include nine specific situations, including constitutional prohibitions, non-engagement in business, non-taxable income categories, and certain exempt entity types.

Establishes personal liability for unpaid gross excise tax amounts and removes provisions holding officers and responsible persons liable for interest and penalties on general excise taxes.

Limits personal liability of officers and managers to only general excise taxes (excluding interest and penalties) that became due during the period they had control or responsibility for the taxpayer.

Takes effect July 1, 2030, and applies to gross income or gross proceeds received on or after that date.
