Taxing entities in Utah have been less anxious to hike their rates since the state Legislature enacted its "truth in taxation" legislation in 1985.

The measure, which requires that taxpayers be informed of a public hearing whenever local government officials plan to raise property taxes, has stifled property tax growth.A Utah Foundation report released Monday shows that the average property tax on a $75,000 home rose from an annual rate of $522 - .74 percent - in 1981 to $737, or .98 percent, in 1988. But the rate of increase slowed dramatically after 1985, rising only .01 percent in each of the past three years.

In 1983 and 1984, rates rose .10 percent and .08 percent, respectively.

Though the average property tax charged on a $75,000 home in Utah was $737 last year, the average tax ranged from a low of $343 in the unincorporated area of South Summit School District to a high of $907 in Sandy.

One of the major elements of Gov. Norm Bangerter's six-point tax limitation plan was the freezing of property taxes at current levels and a requirement that a vote of the people would be needed to raise them. But because of opposition from local officials and the difficulty of arriving at an acceptable compromise, the report says, the freeze was not approved by the 1989 Utah Legislature.

Still, local officials agreed to avoid any property tax increase this year, if possible.
