An $80 million tax cut was put on the table Wednesday by a leader of the Legislature's Tax Reform Task Force as a way to advance a single sales-tax rate for the state.

The cut would be offset by the recent increase in state tax revenues — and so no existing programs would be harmed, according to Rep. Wayne Harper, R-West Jordan, the co-chairman of the task force and the legislator behind the push for a uniform state sales tax.

"It's reining in state spending and growth," Harper said of the proposal, describing it as intended "to soften the impact to taxing entities" of switching some sales taxes to property taxes.

All of this is part of Harper's plan to set a 6.25 percent sales tax rate statewide.

There are now 96 different tax rates across the state. The system is confusing to businesses and consumers alike and actually harms economic development, single rate advocates say.

Some of the local option sales taxes — "boutique" taxes levied for services such as zoos, arts and parks (the ZAP tax), transit districts or rural hospitals — would be added onto property tax bills, Harper explains. And property tax rates would be adjusted in an attempt to offset that shift, he adds.

The proposal is far-reaching and complicated. Some areas will see a slight property tax reduction and a sales tax cut. Others will see a mix — one tax up, the other down. If a sales tax actually went up, Harper's plan would attempt to offset that with property tax cuts.

But because the growing income tax will be used to offset drops in the sales and property tax — and all of the state income tax is dedicated to public schools — some lawmakers are complaining Harper's laudable goal has the potential of harming school funding.

Reducing the school district portion of property taxes by $80 million statewide would cut property taxes by $61 on a house valued at $181,000. But, in some areas with boutique taxes the property tax rate would increase under the proposal.

For example, in Salt Lake County, property taxes on a $181,000 house would go up a total of $32 because of the ZAP tax and the amount collected for mass transit. Hardest hit would be outlying areas of the state where a rural hospital tax is added to the sales tax rate.

The biggest increase in property taxes under the proposal, $109, would be in Henrieville. Like other communities in Garfield County, the tiny town levies a rural hospital tax to pay for the area's municipal medical facility.
