Is my property over-assessed in Hennepin County?
You're over-assessed when the County's value is higher than what your home would actually sell for — and then you're over-paying every year until you appeal. Minnesota homeowners first appeal to the Local and County Boards of Appeal & Equalization (April–June; dates are on your Notice of Valuation), then to the Minnesota Tax Court by April 30 of the year the tax is payable, per Minn. Stat. §271.06/§274.01.
Honest null: Hennepin County's assessment roll isn't onboarded into our live check yet, so we can't pull your specific over-assessment here. Compare your assessed value to recent nearby sales on the county assessor portal — if it's higher than what your home would sell for, you're over-assessed and should appeal by the deadline above.
How to appeal your Hennepin County assessment — and who files it for you
Pull your current assessed value from the Hennepin County assessor portal.
Find your market value — a recent sale of your home, or comparable nearby sales.
If the County's number is higher, file an appeal with the Local/County Board of Appeal & Equalization → MN Tax Court by April 30 (Tax Court; local/county Boards earlier).
Present your comparables (and any appraisal) at the hearing.
Most owners who win use a contingency property-tax appeal firm — it costs nothing unless they cut your bill, then takes a share of the first-year saving. About 95% of over-assessed owners never appeal, so the saving is usually left on the table.
