Most of the money from a proposed 10-cent increase in Alabama’s state fuel taxes would go to state road projects, but counties, cities and towns would also see a boost in their allocations for roads and bridges.

The Legislature is meeting in a special session called by Gov. Kay Ivey to consider the plan, which would raise an estimated $320 million a year when fully implemented. A House committee is scheduled to consider the three-bill package on Thursday.

Committee approval could put the bills in line for a vote by the House on Friday.

The state gasoline tax, which has been 18 cents a gallon since 1992, would rise by 6 cents this year and 2 cents each of the following two years. The state diesel tax, 19 cents a gallon since 1992, would rise by the same amounts.

Associations representing city and county governments support the tax. Mayors and county commissioners appeared with Ivey at a press conference last week.

Two-thirds of the money would be allocated to state projects. Twenty-five percent would go to counties and 8 percent to municipalities. A separate portion, about $12 million a year, would be used for to support a bond issue for improvements to the shipping channel for the Alabama State Docks in Mobile.

The 8 percent share for municipalities would be distributed two ways. Twenty-five percent would be distributed in equal shares and 75 percent would be distributed based on population.

Overall, municipalities would get a bigger share of the new revenue than they do from the current 18-cent tax.

One of the biggest differences would be for Birmingham, which gets a smaller cut than other large cities in Alabama under the current formula, partly because there are so many other municipalities in Jefferson County.

Here are the increases some of Alabama’s major cities would see from the 10-cent tax increase, as compared to revenues from the fuel tax in fiscal year 2017.

Birmingham: An additional $1.4 million, for a total of $1.5 million.

Huntsville: $1.2 million, $4.8 million total.

Mobile: $1.3 million, $2.2 million total.

Montgomery: $1.4 million, $2.1 million total.

Tuscaloosa: $626,000, $1.1 million total.

Huntsville’s total is larger because it gets a larger share of the local revenue from the current 18-cent tax than other cities because of local legislation that applies to Madison County, according to Greg Cochran, deputy director of the Alabama League of Municipalities.

Here’s a link to a chart with a breakdown of every city and town in Alabama.

Here are the increases some of Alabama’s largest counties would see when the 10-cent tax increase is fully implemented as compared to revenues in fiscal year 2017:

Jefferson County, an additional $6.5 million, a 42 percent increase.

Madison County, an additional $3.7 million, a 90 percent increase.

Mobile County, an additional $4.3 million, a 47 percent increase.

Montgomery County, an additional $2.6 million, a 45 percent increase.

Tuscaloosa County, an additional $2.4 million, a 47 percent increase.

Madison County’s percentage increase is higher than the other counties because the distribution of the current 18-cent tax is different in Madison County, with a larger share going to the cities than in other counties.

Besides the tax increase, a provision in the bill allows counties to swap federal funds for a new allocation from the state. The new allocation will be less than the federal funds but counties can do more with the state money because they won’t be subject to certain federal restrictions, according to Sonny Brasfield, executive director of the Association of County Commissions of Alabama.

A new version of the gas tax bill introduced today would create an annual registration fee of $200 for electric vehicles and $100 for hybrid electric vehicles. Those fees are lower than originally proposed in the legislation released last week.

One-fourth of the revenue from the fees would go to a program to award grants for the establishment of electrical vehicle charging stations. The rest would be distributed according to the same formula as the increased fuel tax, 67 percent to the state, 25 percent to counties and 8 percent to cities.

This story was corrected at 7:30 a.m. on March 26 to say that the new amounts reported for the five cities is based on the full 10-cent tax increase, not the first 6 cents.
