Look to sales tax on gas to help fix Michigan roads, report suggests

The state charges a 6 percent sales tax on gasoline purchases, but the revenue doesn鈥檛 go to fix roads. A new analysis suggests removing the sales tax from fuel sales would allow Michigan lawmakers to raise the state gasoline tax, which does go to fixing roads, without causing gas prices to rise.

Michigan policymakers looking to find money to fix the state crumbling roads should consider untying the sales tax from gasoline sales, according to聽.
Doing so would allow lawmakers to increase the state gas tax by roughly 15.5 cents per gallon 鈥 replacing the estimated $894 million in annual sales tax revenue from fuel purchases that now doesn鈥檛 go to fixing roads 鈥 without also causing gas prices to rise, said Eric Lupher, president of the nonpartisan Citizens Research Council of Michigan, which evaluated the state road-funding options.
That because, even though Michigan levies its 6 percent sales tax on gasoline, the money collected at the gas pump goes instead to public schools, local revenue sharing and public transit.
鈥淭he disentanglement of motor fuels and the Sales Tax should be a priority,鈥 according to the Citizens Research Council analysis,聽
鈥淓xempting motor fuels from the Sales Tax and increasing fuel tax rates an equal amount would make taxation on motor fuels more transparent and promote the user fee approach ingrained in road funding in Michigan.鈥
Removing the sales tax on gasoline, however, would create a shortfall in several other budget areas, including schools.
Such are the choices lawmakers face, as Michigan road-funding debate is poised to begin in earnest.
Democratic Gov. Gretchen Whitmer聽聽in her first budget presentation next week. Several independent studies have found that Michigan is聽聽of the amount needed today to fix existing roads.
Former Republican Gov. Rick Snyder in 2015 signed into law a $1.2 billion road-funding package consisting of higher gas taxes and vehicle registration fees and diverted income taxes that won鈥檛 be fully phased in until 2021.
Experts since have said Michigan roads will continue to deteriorate because the amount of revenue is insufficient to get enough roads into good or fair condition.
Republican legislative leaders 鈥 Senate Majority Leader Mike Shirkey and House Speaker Lee Chatfield 鈥 have said that while new money is needed to reverse Michigan decades-long disinvestment in roads,聽聽in current spending.
Chatfield has said he supports聽, but has not outlined a specific plan to replace the money that goes to schools and other programs.
鈥淚t would be desirable with such a policy decision to backfill the School Aid Fund and to add to state revenue sharing funding with revenues from other taxes to make up for the revenue decline caused by the shrunken tax base,鈥 Citizens Research Council wrote.
The analysis breaks down the pros and cons of multiple road-funding options.
Gas taxes, for instance, amount to a user fee on roads users, but are an unreliable long-term option as cars become more fuel efficient. Borrowing money can speed construction timelines but leave Michigan indebted.
The analysis offers several principles that it says policymakers should consider when deciding how to address Michigan road-funding shortfall, including:
If existing general fund resources are used for roads, don鈥檛 create problems for other areas of the budget.聽Policymakers should look at backfilling the spending that has been taken from another state program or department, Lupher said in an interview.
鈥淚f roads are our highest priority, then we should fund it accordingly, so nothing should be off the table,鈥 he said.
鈥淎t the same time, we do have other priorities, and let not create a problem for corrections or universities or K-12 education to fix this problem.鈥
Bonding is a useful tool, but it not a way to raise money for ongoing road maintenance.聽Instead, Lupher said, bonds are best used for one-time, large projects, such as a freeway reconstruction, because they have to be repaid over long periods of time, with interest.
Any discussion of road funding also should include a conversation about the formula used to distribute road dollars to cities, villages and counties.聽Revenue from state gas taxes and vehicle registration fees is divided among the state, cities and counties for roads聽. The state and counties each get 39 percent of the funding, while cities and villages receive 22 percent.
鈥淭he current Act 51 allocation ignores road capacity, which is a true indicator of costs, and road usage, which is a key driver of degradation,鈥 according to the report. 鈥淚t does not direct funds to the roads in the poorest condition. If funding does not reflect the realities on the ground, increases will have less of an effect on road condition, while some road agencies will be over-funded.鈥
Piecemeal approaches to road funding will not work.聽Regardless of the method, raising enough money to fix the roads for the long term 鈥渨ill require a significant investment from the state,鈥 the report states. 鈥淏oosting funding in small amounts, or for short periods of time, will mean new construction and maintenance will not be maintained as efficiently. If the legislature chooses to increase funding, those increases should be sufficient to reconstruct roads to high standards and maintain them throughout their life cycles.鈥
