Mirroring what's happening on a federal level, it's "anything but a state gas tax increase" when it comes to raising needed funds for transportation programs in Missouri. The state gas tax of 17.3-cents per gallon, sixth lowest in the nation [PDF], hasn't been raised for 18 years, according to the April, 2014 chart from the Institute on Taxation and Economic Policy (PDF).
While transportation sales tax measures have become more popular since Arkansas voters overwhelmingly supported a measure in Nov., 2012, how voters view a sales tax increase associated with an income tax cut is yet to be seen. "Opponents argued that lawmakers were sending mixed messages by cutting taxes with one vote and asking voters to increase taxes with another," writes Rudi Keller, statehouse reporter for the Columbia Daily Tribune.
"I think that message is going to come out loud and clear, and what it is going to be is we are going to turn this down," said Rep. Bill Otto, D-Maryland Heights.
Adds Virginia Young of the St. Louis Post-Dispatch, "Critics say sales taxes are hardest on low-income people because a higher percentage of their income goes toward buying essential items." Poorer residents are more likely to pay little of no income tax, thus they are less likely to benefit from the income tax cut.
A far less popular approach would be to allow voters to increase income taxes for transit, as some in Indiana will decide in November.
"Missouri currently funds transportation programs with a combination of fuel taxes, registration fees and sales tax on vehicles." Adding a general sales tax to the mix would detract from the "user fee" approach, though other states, most significantly Virginia last year, made the change. Other states have resorted to wholesale fuel taxes as opposed to general sales taxes.
Based on current sales tax receipts, the measure would raise approximately $540 million each year, with 10 percent set aside for city and county governments. The remainder would pay for highways, mass transit, ports, airports and bicycle and pedestrian transportation.
The bi-partisan legislative vote calls for a "November statewide ballot unless Gov. Jay Nixon decides to put it before voters in August. The proposed constitutional amendment would impose the tax for 10 years, with automatic votes for renewal every 10 years," writes Keller.
