File if you believe your assessment is too high or inaccurate. Common reasons: overassessment vs. market value, lower assessments on comparable properties, incorrect property records (square footage, rooms, classification), condition problems, or—for commercial—declining income or higher vacancy. Filing directly with the county is free but doesn't guarantee a reduction and must occur within the deadline.
