Winona County Property Tax Appeal Guide
In Winona County, file your appeal by April 30, 2026 at Winona County Assessor's online portal.
| Deadline | Minnesota uses a sequential board-session track. First, attend your jurisdiction's informal review (the assessor's Open Book meeting) or appeal in person at the Local Board of Appeal and Equalization, which meets between April 1 and May 31 and must adjourn within 20 days of convening. If unsatisfied, appeal to the County Board of Appeal and Equalization, which meets in June. You must appeal to the Local Board before the County Board. Alternatively, you may skip the boards and petition the Minnesota Tax Court directly; the petition must be filed on or before April 30 of the year in which the tax becomes payable (i.e., April 30, 2026 for the assessment that determines taxes payable in 2026). |
