What is a Minnesota Property Tax Appeal?
A Minnesota property tax appeal is the formal process of challenging your property's assessed value with county or state authorities. When your property is over-assessed, you pay more in property taxes than you should. The appeal process allows property owners to present evidence that their assessment is too high and request a reduction.
Property tax appeals are especially important for commercial, industrial, and apartment property owners because these properties are often assessed using income-based approaches that may not accurately reflect market conditions. A successful appeal can result in thousands—or tens of thousands—of dollars in annual tax savings.
Key Point: The Assessment vs. Tax Distinction
You're appealing your property's assessed value, not the tax rate. The tax rate is set by local governments. However, reducing your assessed value directly reduces your property tax bill because taxes are calculated as: Assessed Value × Tax Rate = Property Taxes.
Who Can Appeal Property Taxes in Minnesota
In Minnesota, property tax appeals are available to owners of all property types. However, the complexity and potential savings vary significantly by property type:
Best Candidates for Appeal
- Commercial properties (office, retail, mixed-use)
- Industrial properties (manufacturing, warehouse)
- Apartment buildings (5+ units)
- Properties with recent value decline
- Properties with high vacancy rates
Also Eligible
- Single-family homes
- Small residential rentals (1-4 units)
- Vacant land
- Agricultural property
Note: Smaller properties may not justify professional help due to limited savings potential.
Tenants can also benefit. If you're a commercial tenant with a triple-net (NNN) lease, you're likely paying your proportionate share of property taxes. A successful appeal by the landlord—or one you initiate—can reduce your occupancy costs.
Critical Minnesota Property Tax Appeal Deadlines
Missing a deadline means losing your right to appeal for that tax year. Minnesota has strict deadlines that vary by appeal type:
Most Important: April 30 Tax Court Deadline
Tax Court petitions must be filed by April 30 of the payable year. This is the final opportunity to appeal your assessment for that tax year.
March: Assessment Notices Mailed
Review your notice immediately. This starts your window to appeal informally at Open Book meetings.
April: Local Board of Appeal Hearings
Present your case to the Local Board of Appeal and Equalization (LBAE). Deadlines vary by city.
April 30: Tax Court Petition Deadline
Final deadline. If you miss this, you cannot appeal your assessment for this tax year.
June: County Board of Appeal Hearings
Last informal appeal option. Check your county for specific dates.
August 1: Mandatory Disclosure Deadline
For Tax Court petitions on income-producing properties, financial documents must be submitted by this date or your case may be dismissed.
Informal Appeals vs. Tax Court Petitions
Minnesota offers two paths to challenge your property tax assessment: informal appeals and formal Tax Court petitions. Understanding the differences helps you choose the right approach.
Informal Appeals
What it is:
Meetings with assessors or local boards to negotiate value changes without formal legal proceedings.
Types:
- Open Book (with assessor)
- Local Board of Appeal (LBAE)
- County Board of Appeal (CBAE)
Timeline:
30-90 days typically
Attorney Required:
No
Best for: Most commercial properties, first-time appeals, smaller reductions
Tax Court Petition
What it is:
Formal legal filing with Minnesota Tax Court. Can settle before trial or proceed to judgment.
Types:
- Regular Division (most cases)
- Small Claims Division (<$1M value)
Timeline:
1-2 years (standard); 90 days (with Insight)
Attorney Required:
Yes, for filing
Best for: Large properties, significant reductions, missed informal deadlines
Strategic insight: Many property owners file a Tax Court petition as a "placeholder" by April 30 while still pursuing informal negotiations. This preserves your appeal rights while attempting a faster resolution.
Step-by-Step Minnesota Property Tax Appeal Process
Here's how a typical property tax appeal works from start to finish:
Review Your Assessment Notice
When you receive your notice (typically March), compare the assessed value to your property's actual market value. Look for errors in property details, square footage, or classification.
Gather Evidence
Collect documentation supporting a lower value: comparable sales, income/expense statements, rent rolls, lease agreements, and property condition reports.
File Your Appeal
For informal appeals, contact your assessor's office. For Tax Court, file a petition with the Minnesota Tax Court by April 30. An attorney must sign the petition.
Present Your Case
Meet with assessors or county attorneys to present evidence. Most cases settle through negotiation without going to trial.
Receive Decision & Refund
If successful, you'll receive a reduction in assessed value. For Tax Court cases where taxes were already paid, you'll receive a refund plus interest.
Evidence Requirements for Minnesota Property Tax Appeals
The strength of your evidence determines your appeal's success. Minnesota uses three valuation approaches, and your evidence should support one or more:
Income Approach
Best for: Apartments, office, retail
- • Rent rolls
- • Operating statements
- • Lease agreements
- • Vacancy data
- • Market rent surveys
Sales Comparison
Best for: All property types
- • Comparable sales
- • Market analysis
- • Price per SF data
- • Time adjustments
- • Location factors
Cost Approach
Best for: Industrial, special-use
- • Construction costs
- • Depreciation schedules
- • Land value studies
- • Functional obsolescence
- • Economic obsolescence
Mandatory Disclosure for Income Properties
By August 1, Tax Court petitioners for income-producing properties must provide: year-end financials, rent rolls, lease agreements, net rentable SF, and next year's budget. Missing this deadline can result in case dismissal.

Property Tax Consultant vs. Attorney: Which Do You Need?
When appealing property taxes, you have three options: do it yourself, hire a property tax consultant, or hire a property tax attorney. Here's how they compare:
| Factor | DIY | Consultant | Attorney |
|---|---|---|---|
| Cost Structure | Free | Contingency (no win, no fee) | Hourly or flat fee |
| Upfront Cost | $0 | $0 | $2,000-$10,000+ |
| Expertise | Limited | Property valuation specialist | Legal procedures |
| Tax Court Filing | Cannot file | Coordinates with attorney | Can file directly |
| Best For | Simple residential | Commercial, industrial, apartments | Complex legal issues |
The key difference: Property tax consultants specialize in property valuation and know what evidence assessors find compelling. Attorneys specialize in legal procedure. For most commercial property tax appeals, a consultant with assessor-side experience delivers better value.
At Insight Property Tax, we combine both: our team includes former county assessors who understand valuation from the inside, and we coordinate with attorneys for Tax Court filings when needed.

Frequently Asked Questions
What is the deadline to file a Minnesota property tax appeal?
For Tax Court petitions, the deadline is April 30 of the payable year. Informal appeals should be filed shortly after receiving your assessment notice in March. Missing these deadlines forfeits your right to appeal for that tax year.
How much does it cost to appeal property taxes in Minnesota?
With a contingency-fee property tax consultant like Insight Property Tax, you pay nothing upfront. The fee is typically a percentage of your tax savings, so you only pay if the appeal succeeds.
How long does a Minnesota property tax appeal take?
Informal appeals typically resolve in 30-90 days. Tax Court petitions can take 1-2 years through standard channels. Insight Property Tax averages 90-day resolution for both types.
Can my property value increase if I appeal?
In rare cases, yes, if the case goes to trial and the court determines the property was under-assessed. Professional consultants protect you by withdrawing appeals before trial if evidence suggests this risk.
What properties are best suited for appeals?
Commercial properties, industrial facilities, and apartment buildings typically offer the best return on appeal efforts due to their higher values and complex valuations. Residential properties can be appealed but often don't justify professional fees.
