We strongly recommend homeowners review their assessments annually and appeal yearly if and when there is a strong argument that their home may not be assessed fairly. Jefferson Township was reassessed last year, but regardless of whether you appealed last year or not, you may appeal every year, including 2025. An appeal in 2025 may generate savings lasting for two years until the next reassessment of Jefferson in 2027. If you’d like a second opinion on your assessed value as it compares to other similar properties, contact us for a free, no-obligation, professional analysis of your property.
