Death of a State Transportation Sales Tax Measure

Partisan politics killed what was labeled as a bipartisan effort to increase funding for Colorado's roads by allowing voters in November to determine whether to raise the state sales tax to fund a bond measure.

House Bill 1242 may have had the backing of the state's Republican leadership, but that didn't stop Senate Republicans, who control that branch of the General Assembly, from killing the measure in committee. 

Despite reducing the size of the sales tax hike from .62 percent to .50 percent, three Republican members of a Senate panel effectively killed the measure, "citing ideological opposition to increasing taxes," reports John Frank for The Denver Post.

The controversial bill had cleared the Democrat-controlled House of Representatives on March 31. "Four Republicans bucked party lines to vote for the measure...The other 24 Republicans voted no, saying lawmakers needed to cut spending on things like Medicaid in order to pay for transportation needs within the state’s existing budget," reported Brian Eason for The Post.

That's the central theme of the transportation lobbying group, Fix Colorado Roads. The first step, they argue, is to establish "a permanent source of general fund dollars for roads" rather than dedicate a new taxing option.

Why a sales tax and not a gas tax?

Colorado's gas tax, 22 cents per gallon was last increased in 1991. In February, it was rated 39th highest in the nation, i.e., only 11 states had a lower tax.

As posted in March, Colorado is the only state to have enacted a TABOR, short for Taxpayer Bill of Rights, which requires legislation that raises taxes be subject to a statewide plebiscite. Polling showed that a sales tax fared better than a gas tax.

The funding plan

"The primary road projects on the list are an expansion of Interstate 25 north and south of Denver and Interstate 70 west through the mountains," reports Frank. "But millions more would have flowed to local governments to repair crumbling local roads and expand transit options."

The emphasis on roadway expansion is also one of the tenets of Fix Colorado Road: "Build large scale roadway expansion programs statewide."

Now what?

"Now that the bill is dead, attention turns to two possible alternatives: a separate far-reaching spending bill aimed at eliminating budget cuts to hospitals that could serve as a vehicle for transportation spending and a handful of potential ballot initiatives," adds Frank. 

They don't have much time—the session adjourns on May 10.
