Valley County Supplemental Tax Bills Mailed Out This Week

Last year, during a dispute with Gov. Greg Gianforte over the state’s “95 mill” school equalization property tax, officials with 49 of Montana’s 56 counties chose to reduce their fall tax bills against the wishes of the Montana Department of Revenue. This month, after landing on the losing side of a November Montana Supreme Court ruling, those counties’ treasurers are left with the thankless task of sending supplemental property tax bills to hundreds of thousands of property owners across the state.

The supplemental bills will increase the amounts homeowners and other property owners owe for the second half of calendar year 2023, payments that are due at the end of May. The exact amount will depend on property type and tax valuations, with homes assessed at a market value of $450,000 owing about $104 extra, according to calculations.

In Valley County, the amount that will be collected with the supplemental tax bills is $500,000.

The entire amount collected with the supplemental tax bills will be sent to the State of Montana.

Valley County Treasurer Brenda Anderson told Kltz/Mix-93 on April 1 that the supplemental tax bills for Valley County are being processed this week and will be mailed April 3.
