Gov. Kay Ivey’s office this afternoon released the bill she is supporting to increase state fuel taxes to boost funding for roads, bridges and the state port in Mobile.

A summary released with the bill mostly covers information previously released but with some new details.

The state fuel taxes, 18 cents per gallon for gas and 19 cents per gallon for diesel, would increase by 6 cents effective Oct. 1, 2019 and an additional 2 cents each of the following years on the same date, for a total increase of 10 cents a gallon.

The tax is estimated to generate about $320 million a year when fully phased in.

Sixty-seven percent of the new revenue will go to the state, 25 percent to counties and 8 percent to cities.

All new revenue from the tax will be deposited into a separate fund, the Rebuild Alabama Fund.

The state, counties and cities can use the revenue only for maintenance or construction of roads and bridges, matching funds for federal road and bridge projects, or the payment of debt, subject to certain restrictions, associated with road and bridge projects.

The money cannot be used for salaries or other compensation that are not direct project costs, purchase or maintenance of equipment, or buildings that are not part of a road or bridge project.

Every other year, beginning June 1, 2023, the Alabama Department of Revenue will compare the National Highway Construction Cost Index to the previous year. Changes in the index can be used to adjust the fuel tax by no more than 1 cent every two years.

The bill would set up a new $250 license and registration fee on electric vehicles and a $125 fee on hybrid-electric vehicles.

Up to $10.2 million annually would be set aside to finance improvements to the ship channel in Mobile Bay to improve access to the Alabama State Docks.

The total cost of the tax increase to the average Alabama driver will be $55 a year, a calculation based on driving 12,000 miles in a vehicle with a fuel efficiency rating of 22 miles per gallon.

The legislative session begins on Tuesday. The bill will be sponsored by Rep. Bill Poole, R-Tuscaloosa.

Ivey said earlier today that lawmakers were getting their first look at the bill today.
