Worth Township filing window
Next window: the Assessor and Board of Review each open once a year; check your property now so you're ready.
Check your Worth property freeWorth Township covers more area than the village that shares its name, and the township—not the municipality in a mailing address—sets the assessment calendar. It was reassessed with the South Triad for 2026 and is next scheduled for reassessment in 2029. The Board of Review opens a Worth Township window every year, including non-reassessment years.
Evidence to review
- Confirm the township and assessment neighborhood in the county record before treating a nearby mailing address as local evidence.
- Compare the subject and each sale by residential class, building style, living area, construction age, and unit count.
- Review lot frontage, land area, and accessory improvements when similar houses sit on materially different sites.
- For repairs or deterioration that sale records do not show, use dated photographs and documents that identify the affected part of the property.
