Residents in Canyons, meanwhile, will pony up a combined total of $6.8 million in additional property taxes — with no action taken by their school board.
Those and other complex budget effects have school officials wondering if state lawmakers thought the whole thing through.
"I hope that in the future if the Legislature looks at equalization, that they look very closely at the unintended consequences," said Janet Roberts, the Salt Lake district's budget administrator.
Born out of the contentious Jordan-Canyons school district split in 2008, the notion of equalization among districts was intended to aid the west-side Jordan School District after it lost a sizeable portion of its property tax base.
Salt Lake County's five school districts — Salt Lake City, Granite, Murray, Jordan and Canyons — were required to levy a capital outlay tax at a uniform rate and deposit those funds into a pool. Cash from that pool was then distributed to all contributing districts on a per-student basis.
"You can accurately describe it as a budgeting quirk," Canyons spokesman Jeff Haney said. "It's one of those things that we have just had to take into consideration as we've put our budget together every year."
Because Utah's tax laws are supposed to stay revenue neutral — with property tax rates floating up and down as home values fall or rise — equalization did not result in surplus funds for the school districts that benefited.
Instead, residents in cash-receiving districts were given various tax discounts, at the expense of their neighbors in other parts of the county.
"It didn't really impact the districts," said Mitch Robison, Granite's budget director. "It impacted the districts' taxpayers."
Initially, Jordan School District took in money from its four neighboring school districts and offset that with tax discounts to its residents.
But trends in population growth and school enrollment now have Canyons School District taxpayers as the largest recipient of other districts' cash, at a combined $6.8 million, followed by Murray School District at $1.2 million and Jordan School District at roughly $480,000.
Those district's tax discounts were mirrored by upward tax adjustments that cost Salt Lake City and Granite residents an additional $7.9 million and $541,000, respectively.
Now, if the five school boards do nothing, Salt Lake City and Granite residents will see tax breaks as the program ends, while taxes will increase for residents in Murray, Jordan and Canyons.
"Canyons is a big shocker," said Jennifer Hansen, assistant director of the Utah State Tax Commission's property tax division. "Their rate will naturally float up a little bit, but it's not considered a tax increase."
