Assessor: sales-study value shifts and homestead phase-outs will change property tax burden

The county assessor's office on Wednesday walked the board through how recent sales studies change taxable market values and thereby reallocate property tax burdens across neighborhoods.

A sample of five residential parcels showed market-value percent changes that in some cases were lower or higher than the countywide average; when a property's market value grows faster than the average, that parcel typically bears a larger share of the tax increase. The assessor noted the homestead market value exclusion phases out once a property's estimated market value reaches $517,200 and that the largest homestead benefit accrues at much lower values, so higher-value properties see less relief.

Examples included a Chanhassen parcel with just under a 3% market-value change and a Waconia property at roughly a 5.7% change, and a Victoria neighborhood that saw a near-20% taxable-market-value jump after an inspection and sales-study adjustments. For commercial property types, the assessor showed one Watertown parcel inspected in 2024 that saw market-value changes near 35% and total taxes rise roughly 44.5%.

The presentation reiterated that changing local values do not mean the county is collecting more overall; rather, the tax burden shifts among property owners depending on how quickly individual parcels change relative to the average. Staff answered commissioners' questions about sample representativeness, green-acre valuation, and procedures for full-sale verification on large commercial or multifamily sales.
