Minnesota Property Tax Deadlines

Minnesota’s calendar runs a full year ahead of its bills: the assessment is set January 2 for taxes payable the following year, and the appeal structure stretches across that gap — board meetings in the spring of the assessment year, and a Tax Court deadline a full year later. It is the only state on this site where the deadlines include meetings you attend rather than only documents you file.

January 2: the assessment date

The county assessor sets estimated market value and classification as of JANUARY 2 of each assessment year, and those figures are used to calculate taxes PAYABLE THE FOLLOWING YEAR (Anoka's own example: the 2025 assessment drives taxes payable in 2026, with the Tax Court deadline April 30, 2026). Assessed values derive from a statutory sales-study window of October 1 to September 30. Valuation notices are mailed on or before April 1. No year-over-year value cap exists; the class-rate system does the distributional work.

April–June: the board meetings are the deadlines

The local appeal boards meet on a STATEWIDE-BOUNDED, locally-set schedule: the LOCAL Board of Appeal and Equalization (usually the city council or town board) meets between APRIL 1 and MAY 31, and the COUNTY Board of Appeal and Equalization (usually the county commissioners) meets in JUNE — the exact dates are printed on each valuation notice. Where a city holds its own LBAE, appealing there is a PREREQUISITE for the county board; cities that transferred their powers to the county hold open book meetings instead. Appeals may be made in person, by letter, or by a representative. There is no fixed filing deadline — the meeting is the deadline.

April 30 of the payable year: the Tax Court

Minnesota allows a DIRECT appeal to the Minnesota Tax Court — no need to exhaust the local boards first. The petition must be filed by APRIL 30 OF THE YEAR THE TAXES ARE PAYABLE (for the 2025 assessment: April 30, 2026). The Court, a specialized executive-branch court under chapter 271, hears petitions on valuation, classification, equalization and exemptions. After the boards, the Tax Court is also the next step for an owner dissatisfied with the county board's outcome.

The notices and the May 15 / October 15 installments

Two notices structure the year: Truth in Taxation notices in NOVEMBER (proposed taxes before budgets are finalized) and property tax statements mailed by MARCH 31. Taxes are due in two equal installments, MAY 15 and OCTOBER 15 (November 15 for agricultural property; $100 or less is due in full May 15). The statement uses the PRIOR year's value, so the tax amount itself cannot be appealed — only the value and classification that produced it.

The shape of a full cycle (illustrative)

Illustrative sequence for the 2026 assessment (taxes payable 2027) — your own notice carries your meeting dates.

  1. January 2, 2026: EMV and classification set, from the October 2024 – September 2025 sales study.
  2. By April 1, 2026: the Valuation Notice arrives — with your board meeting dates printed on it.
  3. April 1 – May 31, 2026: the Local Board’s meeting window (your city’s date is on the notice). Where your city holds its own LBAE, this meeting is the prerequisite.
  4. June 2026: the County Board meets — for owners continuing past the LBAE and open-book residents alike.
  5. November 2026: the Truth in Taxation notice proposes the 2027 tax.
  6. By March 31, 2027: the property tax statement arrives — the value on it cannot be appealed; the deadlines that mattered were last year’s.
  7. April 30, 2027: the Tax Court deadline for the 2026 assessment — the direct route’s last day.
  8. May 15 and October 15, 2027: the two installments (November 15 for agricultural; $100 or less due in full May 15).

What this tells you: Minnesota’s appeal opportunities run backwards relative to the bill — the earliest deadlines (the spring meetings) are the cheapest and most local, and the latest (the Tax Court) is the heaviest. Every door before April 30 of the payable year is open, but each one after the meetings costs more to walk through.

What it does not tell you: your city’s board meeting date (printed only on your notice) and your county’s June session date — published by each county.
