CO HB1205

Imposes an annual "road usage equalization fee" on plug-in electric vehicle registrations set at $75 starting January 1, 2022, then adjusted annually for inflation thereafter.

Fee amount is designed to achieve parity between total registration fees and motor fuel taxes paid by electric vehicle owners compared to gasoline and diesel vehicle owners.

Revenue from the fee must be credited to the Highway Users Tax Fund and distributed: 60% to state highway fund, 22% to counties, and 18% to municipalities, exclusively for maintenance of existing roads.

Requires Department of Transportation and Department of Revenue to form a joint working group by May 15, 2022, to recommend whether the fee should be adjusted based on fuel tax rate changes, vehicle type, weight, or miles traveled patterns.

Takes effect 90 days after final adjournment of the general assembly, subject to voter approval via referendum petition in November 2022, and applies to registrations beginning January 1, 2022 or later.
