There is growing concern in Salt Lake City that a single sales-tax rate for the state of Utah would be detrimental to the city's arts organizations and Utah's Hogle Zoo.

And that concern could force Salt Lake City leaders and Utah's arts community to oppose a plan state lawmakers are pushing to create a simplified sales-tax system. The problem, city leaders and arts advocates say, is that the current version of the single sales-tax plan would eliminate the Salt Lake County Zoo, Arts & Parks tax in 10 years.

"It sounds like the big losers are the arts organizations," Councilman Carlton Christensen said. They've "been very heavily dependent on the ZAP tax."

While Rep. Wayne Harper, R-West Jordan, said he won't have a final bill drafted for another week, his current legislative designs are to create one sales tax rate for the whole state. Such a plan would restrict individual counties from boosting sales tax rates to fund special taxes like ZAP or Davis County's Recreation, Arts and Parks tax.

Utah Symphony & Opera Chief Executive Officer Anne Ewers said any single-rate tax plan that doesn't save arts funding "in perpetuity" is a bad idea.

"Utah Symphony & Opera would support a statewide single-rate sales tax plan, if that plan included a RAP or ZAP component in perpetuity," Ewers said in a statement. "Our concern with the current proposal is that our RAP and ZAP funding would only be preserved for 10 years, after which current beneficiaries would need to solicit individual municipalities, which would be burdensome and most likely result in less funding for the arts."

Arts, parks and zoo advocates point out there is overwhelming support for ZAP in Salt Lake County. Last election voters countywide supported renewing the tax at a 71 percent margin. That's a greater victory than the margin with which President Bush carried the county.

"The ZAP tax has been very successful," Councilman Eric Jergensen said.

The current legislative plan — presented to the Salt Lake City Council by the Utah League of Cities and Towns last week — is that taxes like ZAP/RAP taxes, resort community taxes and rural hospital taxes would be eliminated after the bonds that support those taxes were paid.

Once the bonds are paid, the money that went to those unique funds would likely be transferred to a city's general fund to be disbursed as the city wishes.

Officials from the league say the individual cities would then have to come together with an interlocal agreement and put that money back into an arts or parks fund. Or culture groups would have to hit up each city for funding individually.
