Madison County, Ohio · Property, tax, sales, deed and GIS help

Search Parcels, Values, Taxes & GIS

Find a Madison County parcel by owner name, property address or parcel number, then review the property’s location, 2026 preliminary value, tax history, land, buildings, sales and recorded-deed clues.

This guide explains exactly what to enter, how to read the result, why a record may be missing, and when to use the Auditor, Treasurer, Recorder or GIS map instead of opening another generic property-record website.

Get the quick answer Follow the screenshot Fix a failed search
Do not rely on an owner name alone. Match the parcel number and property address before using the record. The listed owner, mailing address, value, tax status and map may update at different times after a transfer, correction, split or reappraisal.

Quick answer: use the official Auditor search

Open Madison County’s official Advanced Search, choose one search method, and start with the least information possible. Owner names use Last First order. Address searches separate the house number, direction, street name and street type. After opening the parcel, verify its parcel number and address before reviewing valuation, land, improvements, sales or taxes.

1 Choose one field Owner, parcel or address.
2 Open the parcel Select the correct result.
3 Verify two facts Parcel number plus address.
4 Use the right office Tax, deed, map or appeal.

What to click on the Madison County Auditor page

Madison County Ohio Auditor property search page with parcel, owner, address and GIS map options
Use the official Madison County Auditor website to search by owner, parcel number or property address and access tax, sales and GIS tools.
Use the homepage search bar for a fast lookup Enter an owner name, parcel number or simplified address. This is useful when you already know the basic identifier.
Choose SEARCH for separate fields The Advanced Search page gives individual fields for owner, parcel, house number, direction, street name and street type.
Use INFO for services and forms This area leads to explanations, tax-reduction information and downloadable Auditor forms.
Use TOOLS for reports and calculators The official site provides a Sales Report, Sales List, Delinquency Report, Conveyance Fee Calculator and Tax Estimator.
Choose MAP after identifying the parcel Use the GIS map to understand location, nearby parcels and spatial context. Do not treat the displayed line as a survey.
Open the Valuation section for the 2026 preliminary amount The Auditor’s 2026 reappraisal notice says the tentative Tax Year 2026 value appears in the top valuation line.
Screenshot search tip: On a phone, use the SEARCH menu rather than trying to type a long owner or rural road name into the small homepage field. The separate fields make it easier to remove a direction, suffix or first name when the search fails.

Exact property lookup

Search by owner, parcel number or address

Madison County allows a single-field search or an advanced search using multiple criteria. Start with one field. Adding several imperfect details can remove the correct parcel from the results.

Owner-name search
  1. Enter the surname first.
  2. Add the first name only when there are too many results.
  3. Use the site’s published Last First order.
  4. Try a trust, estate, LLC or previous owner.
  5. Remove punctuation and middle initials when nothing appears.
Example: HUNTER JENNIFER
Parcel-number search
  1. Copy the number from a tax bill, deed, closing file or prior property page.
  2. Enter the complete parcel number first.
  3. Check zero versus the letter O.
  4. Verify the address after opening the result.
  5. Save the number for every later office call.
Best exact identifier
Address search
  1. Enter the house number.
  2. Add the main street name.
  3. Leave direction and street type blank initially.
  4. Add abbreviations only to narrow results.
  5. Search the owner or map when a rural address fails.
Start with number + main street

Mobile-home search

The official search includes separate fields for a mobile-home registration number, park name and lot number. Use the registration number when possible; a park name or lot number alone may match more than one record.

Tax Year 2026 reappraisal

How to read the new 2026 preliminary value

Madison County announced completion of the countywide Tax Year 2026 real-estate reappraisal. The parcel’s tentative value appears in the top line of the Valuation section and may be marked as preliminary.

Current tax collection in 2026 Tax Year 2025

The 2026 bills and payment history generally relate to the prior tax year.

→
New preliminary reappraisal Tax Year 2026

Because Ohio collects real-estate taxes one year behind, this value generally affects bills payable in 2027.

Do not compare the new value directly with the current bill

The preliminary 2026 value and the tax currently payable during 2026 refer to different tax years. A higher preliminary value also does not guarantee the same percentage increase in the eventual bill because effective rates, reduction factors, levies, credits and special assessments affect the calculation.

Review these items before contacting the Auditor

2025 appraised value
Preliminary 2026 appraised value
Land and improvement changes
Living area and building details
Acreage and land use
Valid recent sale
Comparable valid sales
Damage or demolition evidence
Value-review warning: Do not argue only that the tax bill is unaffordable or that the percentage increase feels high. A useful value discussion focuses on incorrect parcel facts, the property’s condition, a valid recent sale or comparable market evidence.

First open the parcel and review both valuation years. Then use the official Auditor homepage or phone number to ask whether an informal correction remains available or whether the issue should be preserved for the Board of Revision process.

Late real-estate payment: The Treasurer states that a 5% penalty is added during the first 10 days after a due date and a 10% penalty after 10 days. Interest is added July 1 and December 1 where applicable. Contact the Treasurer for the exact current balance rather than estimating the penalty yourself.

How to check and pay correctly

Open the parcel’s Tax section Review charges, reductions, credits, payments, net due and any delinquency.
Check whether a lender already paid Contact the mortgage company before making a duplicate payment.
Open the Treasurer’s official payment page Use the county page to reach the authorised card-payment service.
Verify the parcel and amount Match the parcel number, owner and address before entering payment details.
Review the processor fee The Treasurer describes the card fee as a nominal service fee. Check the displayed amount before authorising.
Save the receipt Keep the confirmation, parcel number, amount, date and payment method.
Recheck posting A successful processor screen does not always mean the public parcel page updates immediately.

Important warning
Mail
Send the bill stub and check payable to Stacey McKenzie or Madison County Treasurer.
A timely USPS postmark counts; a private-meter date does not.
In person
Pay at the courthouse main floor, 1 N Main Street, London.
Pay by the collection deadline to avoid a mandatory penalty.
Night box
Use the white night box on the west side of the courthouse facing Main Street.
Do not place cash in an unattended deposit box.
Online card
Use the payment route linked by the Treasurer.
A processor service fee applies.
Auto Pay
Use the Treasurer’s automatic-withdrawal agreement for qualifying future payments.
Submit the agreement early enough for processing.
Returned-check fee: The Treasurer lists a $13 returned-check charge.

Missing bill or delinquent balance

Bill never arrived Search the parcel and call the Treasurer. Failure to receive a bill does not excuse late payment.
Recently purchased property Review the closing statement because Ohio taxes are paid one year behind and are commonly prorated at closing.
Mailing address is wrong Notify the appropriate county office rather than waiting for the next bill to be returned.
Cannot pay the full delinquency Ask the Treasurer about a delinquent-payment plan before the account advances further.
Treasurer call script “I am calling about parcel [parcel number] at [address]. I need to confirm the current balance, penalties, whether a payment has posted, and whether a delinquent-payment plan or other payment arrangement is available.”

After checking the parcel and lender status, use the Treasurer’s official payment information page. It provides the live due dates, payment methods, contact information and links to online payment.

Parcel map workflow

Use the GIS map without mistaking it for a survey

Find the parcel in the Auditor search first Copy the exact parcel number before opening the map.
Open MAP from the official Auditor site The county provides its GIS Parcel Viewer through the MAP menu.
Search the parcel or address Use the parcel number when a rural road name, mailing city or new address is inconsistent.
Compare nearby parcels and roads Use the map to confirm location, adjoining parcels and general spatial context.
Return to the parcel details Use the property page for value, ownership display, sales and tax information.
Use recorded records for legal questions Review the deed, plat or survey when an exact boundary, easement or legal description matters.
Fence and construction warning: Do not place a fence, driveway, structure, septic component or utility from the GIS line alone. Online parcel boundaries are reference information and may not represent the exact monumented boundary on the ground.

GIS is useful for

Locating a rural parcel
Checking nearby parcels
Understanding township context
Confirming roads and general shape
Finding a likely parent parcel
Preparing a survey or deed question

Once the parcel number is confirmed, open the official MAP page. Use the map for orientation and the Recorder or a qualified surveyor for legal-boundary work.

Open official GIS Parcel Viewer Go to deed-search steps
Comparable-property research

Use sales reports before challenging a value

Madison County’s official Sales Report groups transactions by price range and displays average, median, minimum, maximum, sale count and parcel count. It can also show matching parcels and export results as CSV.

Build a meaningful comparison

Match location
  • Township or municipality
  • School district
  • Tax district
  • Neighbourhood or rural setting
Match property
  • Property class
  • Living area
  • Year built and condition
  • Acreage and improvements
Match sale
  • Recent sale date
  • Valid sale flag
  • Similar market exposure
  • No unusual transfer circumstances

Transfers that may mislead you

$0 trust transfer
Affidavit or certificate
Quitclaim deed
Family transfer
Multiple parcels in one sale
Foreclosure or sheriff sale
Different school district
Major condition difference
Useful export: Save the CSV with the date range and filters used. Keep the parcel numbers of your strongest comparisons so the Auditor or Board of Revision can review the same records.

After choosing a relevant date range and comparable criteria, use the official Sales Report or Advanced Search. Do not rely only on an online estimate or one nearby sale.

Open official Sales Report Open Advanced Search filters
Recorder land-record workflow

Find deeds, mortgages, liens and easements

Use the Recorder when you need the actual recorded document. The Auditor parcel page helps you identify the owner, sale date, deed type, conveyance number or deed reference, but it does not replace the recorded instrument.

How to check whether a reduction already appears

  1. Open the property record.
  2. Scroll to the Tax section.
  3. Look for owner-occupancy credit, Homestead or CAUV-related fields.
  4. Check whether the amount is zero or a deduction is shown.
  5. Call the Auditor when approval was expected but the current parcel does not show it.

CAUV preparation

Initial application
  • Use the current DTE 109.
  • Describe qualifying agricultural use.
  • Prepare acreage and income records when required.
  • Do not assume vacant acreage automatically qualifies.
Annual responsibility
  • Use DTE 109A for renewal.
  • Meet the deadline printed on the current form.
  • Report ownership and use changes.
  • Understand that withdrawal can create recoupment.

After choosing the correct programme, use the Auditor’s live forms library. Filter by Tax Reduction, Agricultural Use or Property Transfer rather than downloading a form from another county.

Board of Revision preparation

Challenge a value with evidence, not guesswork

A Board of Revision complaint should address the parcel’s value. It is not a request to remove a voted levy, change the tax rate or erase a valid special assessment.

Confirm the value year Identify whether you are questioning the current 2025 value or the preliminary Tax Year 2026 reappraisal value.
Check every property fact Review acreage, class, living area, year built, condition, improvements and agricultural status.
Find valid comparable sales Match location, property type, size, condition and sale timing.
Use the current DTE 1 Download the complaint form and BOR Rules of Practice and Procedure from the Madison County forms page.
State the requested value Explain how the evidence supports the requested market value rather than only stating that the current value is too high.
Confirm the filing window Ohio’s normal annual complaint period is generally January 1 through March 31. Confirm the exact year, deadline and delivery instructions on the current form.
Keep proof of submission Save the email, delivery receipt, stamped copy or other filing confirmation.

Ten practical answers

Madison County Auditor property search FAQs

How do I search Madison County Ohio property records?

Use the official Madison County Auditor Advanced Search. Search by owner name in Last First order, parcel number, property address or mobile-home information, then open the correct parcel and verify the address and parcel number.

Can I search Madison County property records by address?

Yes. Enter the house number and street name first. Add the direction and street type only when needed. Leaving out abbreviations during the first search often prevents formatting differences from hiding the correct record.

What does the preliminary 2026 value mean?

Madison County completed its Tax Year 2026 reappraisal and displays the tentative 2026 value in the top line of the parcel’s Valuation section. Because Ohio property taxes are collected one year behind, the Tax Year 2026 value generally affects bills payable in 2027.

What is the difference between appraised and assessed value?

Appraised value is the Auditor’s estimate of market value. Ohio assessed value is generally 35 percent of appraised value. The assessed value is then used with the parcel’s effective tax rates, reductions, credits and special assessments.

When were Madison County real-estate taxes due in 2026?

The Treasurer published February 13, 2026 as the first-half real-estate due date and July 15, 2026 as the second-half due date. Both regular deadlines have passed, so owners with an unpaid balance should contact the Treasurer for the current amount, penalty and payment options.

Are Madison County GIS parcel lines legally exact?

No. The GIS map is useful for finding parcels, nearby lots and map context, but it is not a boundary survey. Use recorded deeds, plats and surveys and consult a qualified surveyor before making a boundary, fence or construction decision.

Where can I find a Madison County deed or mortgage?

Use the Madison County Recorder’s authorised online land-record search. Registration is required for online access. Use the owner names, conveyance number, deed reference and transfer date from the Auditor parcel record to narrow the document search.

How do I challenge a Madison County property value?

Review the parcel facts, preliminary value, valid comparable sales and physical condition first. Use the current DTE 1 complaint form and the Board of Revision rules published on the Auditor forms page. Confirm the applicable filing window and submission instructions before filing.

Where can I find Homestead, owner-occupancy and CAUV forms?

The Madison County Auditor forms page includes DTE 105A for qualifying Homestead applicants, DTE 105C for the owner-occupancy reduction, DTE 109 for an initial CAUV application and DTE 109A for annual CAUV renewal.

Who should I call about a Madison County property-tax payment?

Call the Madison County Treasurer at 740-852-1936 for tax bills, payment posting, missing bills, penalties and delinquent-payment plans. Call the Auditor at 740-852-9717 for values, property facts, Homestead, owner occupancy, CAUV and valuation complaints.

Facts verified July 26, 2026: The property-search fields, 2026 reappraisal notice, office details, sales tools, forms, conveyance fees, tax dates, payment rules and Recorder search information were checked against Madison County’s official Auditor, Treasurer and Recorder resources. Recheck the responsible office before a payment, deadline, filing or visit.

These calculators use the verified 2026 Ohio Department of Taxation amounts and statutory rules. For your exact bill, exemption status, and county-specific deadlines, always confirm with your county auditor and the Ohio Revised Code:

Ohio Dept. of Taxation — Real Property DTE Forms (105A, 105C, 1, 109) ORC 5715 — Board of Revision ORC 5713 — Taxable Real Property ORC 322.02 — Conveyance Fee ORC 319.54(F)(3) — State Fee ORC 5713.30 — CAUV tax.ohio.gov — Main Portal

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. The 2026 Homestead general amount ($29,000) and enhanced amount ($58,000) reflect HB 187 inflation indexing — your county auditor's office may show slightly different transitional figures.
