CO SCR003

Submits to Colorado voters a proposed constitutional amendment titled "Stop Digging the Hole Amendment" for the November 3, 2020 election.

Requires the General Assembly to repeal all state excise taxes on gasoline and other liquid motor fuels (diesel, compressed natural gas, liquefied natural gas, and liquefied petroleum gas) effective July 1, 2021, while preserving the aviation fuel tax.

Mandates implementation of an additional state sales and use tax on and after July 1, 2021, calculated to offset 99% of the state revenue loss from repealing motor fuel taxes for fiscal year 2021-22.

Credits all net revenue from the additional sales tax to the Highway Users Tax Fund, allocated to state, counties, and municipalities in a manner preserving existing allocations, with funds used exclusively for surface transportation construction, maintenance, and supervision.

Requires voter approval of at least 55% for the amendment to become part of the state constitution and designates voter approval as advance authorization under the Taxpayer's Bill of Rights for the state to retain and spend revenue exceeding 2020-21 levels.
