Madison County Overview
Madison County Tax Assessment Process
The Madison County Auditor is the chief assessor for all real property. ORC Chapter 319 requires the auditor to view and value every parcel. Madison County has a lot of farmland, which makes up most of its land area. Residential properties cluster around London and a few smaller villages. The eastern townships have seen suburban growth from Columbus. The auditor assigns market value to each parcel and applies the 35% assessment rate required by Ohio law.
Full reappraisals happen every six years. The triennial update at the midpoint keeps values current between cycles. During a reappraisal, staff check sales data, building permits, and property conditions. The eastern side of Madison County may see more value growth because of development pressure from Columbus. House Bill 920 reduction factors help offset the impact of rising values on existing levies. Farm owners should watch reappraisal years closely since CAUV values can shift too.
Searching Madison County Property Records

Tax Rates and Levies in Madison County
Tax rates in Madison County vary by district. Each district combines levies for schools, fire, township roads, libraries, and county operations. Rates are stated in mills. One mill is one dollar per thousand of assessed value. A property assessed at $45,000 in a 70-mill district would owe $3,150 before credits.
ORC Chapter 5705 governs tax levies across Ohio. Most new levies require voter approval. House Bill 920 reduction factors keep existing levy revenue steady when values change. Madison County homeowners with a primary residence get the 2.5% owner-occupied credit. The 10% non-business credit applies to residential property not used for business. These credits together reduce the final bill.
Madison County Property Tax Exemptions
Several tax relief programs are available in Madison County. The homestead exemption lets seniors 65 and over, or people with permanent disability, exempt up to $25,000 of market value. Veterans with 100% service-connected disability can exempt up to $50,000. Apply at the auditor's office.
The CAUV program is heavily used in Madison County given the amount of farmland. It taxes agricultural land based on production value instead of its full market price. For large farms, this can cut the tax bill by thousands of dollars. The auditor reviews CAUV applications each year. Forest land may also get reduced rates under ORC Chapter 5713.
- Homestead exemption for seniors and disabled residents
- Enhanced homestead for 100% disabled veterans
- Owner-occupied credit of 2.5%
- Non-business credit (10% rollback)
- CAUV for farmland and qualifying forest
