Search Values, Tax History, Sales, Maps and Deed Clues Without Guessing
Madison County’s Auditor website is built around practical property tasks: look up a parcel, view tax appraisal and payment history, run recent sales reports, estimate taxes, calculate conveyance fees, check GIS maps and download real estate forms.
This guide turns those official tools into a clean workflow for London, West Jefferson, Plain City, Mount Sterling, South Solon, Midway and rural Madison County properties — including revaluation dates, tax due-date changes, CAUV, Homestead, Recorder records and transfer research.
Fast answer: Use the official Madison County Auditor Search for parcel, owner, address, sales, valuation, mobile home and tax-history research. Use the MAP link for GIS parcel viewing, the Tax Estimator for 2025 taxes due/payable in 2026, and the Recorder’s online search for recorded land documents.
2026 watch point: The Auditor notice says Madison County completed the 2026 real estate reappraisal. Tentative values appear in the top line of the Valuation section, and informal valuation-review dates are listed for July 10, July 13 and July 14. Because of HB 186, the Treasurer’s Office delayed tax-bill mailing and lists the second-half due date as July 15, 2026.

Which Madison County Property Tool Should You Use?
Madison County searchers usually need one of four official record paths: Auditor, Treasurer, Recorder or GIS. Use the right one before relying on a number.
How to Search Madison County Auditor Property Records
Open the official search page
Go to Madison County Auditor Search. The official page says you can find parcels by a single search parameter or use advanced search for multiple parameters.
Start with parcel number if possible
Parcel number is cleaner than owner or address. Use it from a tax bill, deed, closing document, old appraisal card or GIS map result.
Use owner name correctly
The official search labels owner name as Last First. If a trust, business or estate does not show, search fewer words first.
Use address fields carefully
Address search separates house number, direction abbreviation, street name and street type abbreviation. Too much formatting can hide the correct record.
Use the parcel tabs after opening a record
Madison County parcel records can show location, valuation, legal, residential/agricultural/commercial details, improvements, sales, land and tax information.
Advanced Search Fields That Matter in Madison County
Owner search
Use Last First format. Try partial last name for trusts, estates, LLCs and long business names.
Parcel search
Best for exact lookup. Use the exact parcel number from a tax bill, deed, title file or previous property card.
Address search
Enter house number, direction, street name and street type separately when possible.
Mobile home search
The search page includes registration number, park name and lot number fields for mobile home records.
Sales filters
Advanced search includes sale date, sale price, buyer name, seller name and valid-sale filter.
Tax district filters
Tax districts include Canaan, Darby, Deercreek, Fairfield, Jefferson, London, Mt. Sterling, Plain City, Somerford, Union and more.

Estimates use Ohio's 35% statutory assessment ratio and effective tax rate tiers averaged across major Ohio counties. Your actual bill depends on local school levies, voted millage, inside vs. outside millage splits, House Bill 920 reduction factors (HB 920), and special assessments.
