A small business advocacy group has launched a campaign against a ballot measure that would reduce property tax rates, but backfill revenue with money collected above state constitutional limits imposed by the Taxpayers Bill of Rights.

“We’re calling out Proposition HH for what it really is, a bait and switch offering a temporary property tax cut, but undoing TABOR refunds,” said Tony Gagliardi, Colorado state director of the National Federation of Independent Business.

The campaign will include radio advertisements in select Colorado markets, digital ads and a landing page with more information in which people also can access the radio ad.

Proposition HH will appear on the November election ballot. The measure would reduce state tax assessment rates for residential and commercial properties, but also backfill reduced tax revenues for local governments and school and special districts with other revenue collected above TABOR limits. That could in turn reduce the money the state returns to taxpayers through so-called TABOR refunds.

“Colorado’s small business owners have trusted the Taxpayer Bill of Rights for 30 years to return some of their hard-earned money back to them,” Gagliardi said. “When we surveyed our members, 90 percent of them opposed Prop. HH. They’re just not buying the deal.”
