Commercial & Business Property
Minnesota Commercial Property Tax Appeals
Office, retail, industrial, multifamily, and special-purpose buildings in Minnesota are frequently over-assessed. Here's how commercial assessments work, the deadline to challenge yours, and what it takes to win.
How commercial is assessed
Minnesota applies class rates: commercial-industrial carries a higher class rate than residential and is also subject to the state general tax, which applies only to commercial/industrial and seasonal property.
Commercial-industrial has a higher class rate AND pays the state general tax.
Burden of proof
The property owner (or their authorized agent) bears the burden of proving the assessment exceeds market value. The assessor's value is presumed correct until rebutted with credible evidence.
Key to a Minnesota commercial appeal: The state general tax on C/I
Commercial/industrial pays an extra statewide levy homes never see, so the effective burden is higher and a value reduction compounds. Open Book with the assessor, then the Local/County Boards, then Tax Court (deadline Apr 30).

⚠️ Deadlines vary by county/municipality in Minnesota. Confirm the exact date for your property's jurisdiction before filing.
How commercial value is proven
Income-producing commercial property is usually valued by capitalizing net operating income (NOI ÷ market cap rate). The strongest appeals come with a clean rent roll, a trailing-12-month operating statement, current vacancy, and market cap-rate support. Where the property is owner-occupied or special-purpose, the cost and sales-comparison approaches carry more weight.
Evidence that wins a commercial appeal
- Current rent roll and a trailing-12-month operating statement
- Actual vacancy and collection loss (vs the assessor's stabilized assumption)
- Market capitalization rate support for the property type and submarket
- Recent arm's-length sales of comparable commercial buildings
- Evidence of physical, functional, or economic obsolescence
- Any change in use, tenancy, or condition since the assessment date
How to appeal a commercial assessment in Minnesota
- 1Pull the assessment — confirm the assessed value, the assessment ratio/class, and how the assessor derived it (income, cost, or sales).
- 2Build the valuation — capitalize actual net operating income and gather comparable sales to establish market value as of the assessment date.
- 3File before the deadline — submit to Local Board of Appeal and Equalization, then County Board, then Tax Court by Local board meeting date (check your county); Tax Court by April 30 of payable year, with the authorization signed by someone able to bind the owning entity.
- 4Present at the hearing — commercial hearings are evidence-driven; a clean income approach and credible comps carry the day.
