Missouri Voters Rejects Legislative Gas Tax Increase

Missouri legislators approved a bill at the end of the legislative session to place a 10-cents per gallon gas tax increase on the ballot to fund road repair. It had the support of Gov. Mike Parson but was rejected by nearly 54 percent of voters.

Proposition D, one of seven measures on last Tuesday's ballot in Missouri, asked voters to "increase the motor fuel tax by two and one-half cents per gallon annually for four years beginning July 1, 2019," according to the Secretary of State's office.

If passed, this measure will generate at least $288 million annually to the State Road Fund to provide for the funding of Missouri state law enforcement and $123 million annually to local governments for road construction and maintenance.

Constitutional restrictions and contrast with California

Missouri's gas tax, at 17.35-cents per gallon, is the second lowest in the nation after Alaska. Gas prices, averaging $2.39 per gallon, according to Gas Buddy, are the sixth lowest in the nation.

By contrast, California voters last Tuesday, by slightly more than the percentage that rejected Missouri's 10-cents increase, voted against repealing a 12-cent increase in the gas tax and 20-cents increase in the diesel tax. What makes the contrast so startling is that California's gas tax of 55.53 cents per gallon is the nation's second highest, and gas prices, averaging $3.71, are the nation's second highest.

"Proposition D was on the ballot due to constitutional requirements for voter approval of any tax increase above a certain threshold," writes Kevin Pula for the National Conference of State Legislators. The Associated Press indicated that a constitutional amendment approved by voters in 1996 required the legislature to place the authorizing legislation, House Bill 1460 [pdf], before the voters for final approval. AP notes that no general tax has been approved since then.

Had the California gas tax repeal initiative, Proposition 6, passed, that constitutional restriction would have applied to future increases to transportation taxes and fees in California as well.

Another similarity: both states last passed incremental tax increases around the same time, and then went for a generation without increasing it.

Complicated ballot measure?

Proposition D did not simply ask voters to increase the gas tax to pay for road upkeep. As noted above, the revenue would be used to fund law enforcement. FOX 4 news reporter Alana LaFlore explains in the source article and in the accompanying news video.

Money would have gone to the State Road Fund, which supports the Missouri State Highway Patrol. MoDOT is funded from the same pot, and so the money would be freed up for road projects.

That scheme upset Crosby Kemper, Director of the Kansas City Public Library,  who "says he planned to vote for Prop D but decided against it at the last minute," adds LaFlore.

"I just said this is crazy," Kemper said. "This is very badly written. I don't know why this says it`s for law enforcement, but it`s supposed to be for roads."

The "freed-up" money would apparently come from the state's General Fund which would be directed to a new Emergency State Freight Bottleneck Fund. But wait, there's more to confuse the voter.

The title of the proposition is Gas Tax Increase, Olympic Prize Tax Exemption, and Traffic Reduction Fund MeasureIt seems that exempting prizes for Special Olympics, Paralympics, and Olympics from state taxes was a major aspect of the legislation.

An opponent took the matter to court, "claiming the referendum violated the Missouri Constitution because the measure’s wording deals with two topics," reported Jack Suntrup for the St. Louis Post-Dispatch. "A state appeals court in Kansas City on [Sept. 4] dismissed the lawsuit."

Steve Pokin, Springfield News-Leader columnist, reported about the complications at great length and with great exasperation on June 27. "What a mess this initiative is!" he wrote.  

Finally, it should be noted that when the legislature passed the bill asking voters to approve a hike in the gas tax, they also passed legislation to cut corporate and income taxes. Gas tax opponents are quick to point to the regressive aspect of user fees. The Missouri legislature's actions justify that criticism.

What's next? 

"It is unknown what the response will be within the state legislature, " adds Pula of the National Conference of State Legislators. "However, it’s a good bet that transportation funding will return to the chamber floors in some fashion, albeit carrying a scarlet letter from the voters."

In August 2014, the legislature placed Amendment 7, a  temporary 0.75 percent increase on the state sales and use tax to fund transportation projects, on the ballot. The measure was rejected by a greater share of the voters – 59 percent [See additional posts tagged Amendment 7.]
