County assessors tell Senate panel market shifts, credits and court rulings complicate valuations

County assessors told the Senate Tax Committee that recent market trends, statutory constraints and court rulings have complicated property valuation and tax administration across Minnesota.

Josh Hoagland, Hennepin County assessor and chair of the legislative committee for the Minnesota Association of Assessing Officers (MAAO), and Michael (Mike) Shepley, Martin County assessor, described the assessment calendar and how sales data determine values used later for taxes payable. Hoagland told senators a key practical point: taxes paid in a given year are frequently based on sales that occurred many months earlier. He said, "taxes that are paid in 2026 had their basis for valuation established by market conditions 2 and a half years prior with sales from the fourth quarter of 2023 and 3 quarters of 2024."

Assessors explained administrative tools available to them, including the Department of Revenue’s practice of applying market‑condition (time) adjustments to reprice sales to the January 2 assessment date when markets are rapidly changing. They also highlighted sectoral shifts: lakeshore and seasonal-recreation values have continued strong gains since the pandemic; parts of the office tower market are experiencing substantial declines; and agricultural land values have risen to historic highs in some counties, concentrating taxable value and producing local tax shifts.

On solar and reclassification, Martin County’s assessor gave a recent example: a planned 1,500‑acre solar installation scheduled for 2027 involves leases rather than outright sales. Shepley said much of that land now carries ag homestead classification at a roughly 0.5% class rate (about $56 per acre in his county example), but when operating as a solar installation the classification would change to commercial at a 2% class rate (roughly $225 per acre in his illustration), raising property tax on that land and shifting the distribution of levy burden. "When the property is operating as a solar installation, the value of that property will remain as ag land value, but the classification changes to commercial," Shepley told the committee.

Assessors flagged several policy and administrative concerns for the committee: recent statutory changes and court rulings can produce complicated, cascading tax effects for tenants and owners; one assessor asked the committee to consider legislative fixes for a low‑income housing court decision that currently raises questions about charging personal property taxes to tenants of low‑income housing units. MAAO requested legislative clarification to avoid placing administrability burdens on assessors and to prevent unintended taxation of tenants.

The witnesses also reviewed statutory limits on treating conservation sales and easements. Shepley cited Minn. Stat. §273.117 and explained that for conservation restrictions recorded after May 23, 2013, assessors are not permitted to reduce value simply because an easement has been recorded; for other conservation arrangements, assessors must look to use and comparable sales.

Why it matters: assessors stressed that valuation decisions interact with legislative policy (class rates, exclusions and exemptions) and with local levy choices; large shifts in a small tax base can create outsized tax‑burden changes for certain taxpayers. The witnesses urged careful legislative review before making changes that would shift tax burden across classes or geographies.

Ending: Senators and assessors agreed the committee might schedule follow-up briefings on specific issues, including the low‑income housing court decision and the tax consequences of large solar installations and conservation easements.
