Madison County Auditor, OH: Property Search, Records (2026)

Find Madison County Property Records, Taxes and Auditor Services

Looking up a home in London, checking land near Plain City, or trying to understand a property tax bill in West Jefferson? The Madison County Auditor maintains property valuations, owner and parcel records, tax information, agricultural valuation records and several important homeowner services.

You can search most property information online without visiting the courthouse. The official website includes owner-name, parcel-number, street-address and manufactured-home searches, along with GIS mapping, sale reports, tax estimates and downloadable forms.

This guide explains how those services work, what information is useful and how to handle property valuation questions, Homestead relief, tax payments, conveyance fees and other county tasks.

How to Search Madison County Auditor Property Records

The county’s Advanced Search page supports several search methods. If you already know the owner, parcel number or house address, you usually need only one search field.

Search by property owner name

1. Open the official Auditor search.

   Visit the Madison County Advanced Search page.

2. Find Owner Name (Last First).

   The county specifies the last-name-first format. For example, use SMITH JOHN rather than John Smith.

3. Enter the name.

   If you are unsure of the full name, begin with the last name and refine the results as needed.

4. Choose Owner Search.

   Review the properties returned by the system.

5. Open the correct record.

   Compare the property location, parcel identifier and listed owner before relying on the information.

Why might the owner name be different? A property may be held by a trust, business, estate or multiple owners. Recent ownership transfers also need time to appear in county property databases.

Search by street address

1. Open Advanced Search.

   Find the address fields beneath the owner and parcel searches.

2. Enter House #.

   Put the building’s street number in the separate house-number field.

3. Enter Street Name.

   Use the main street name, and complete the direction and street-type fields if needed.

4. Choose Address Search.

   Open the property matching your location.

5. Check its identifying information.

   Record the parcel number for future tax, GIS or ownership research.

Search by parcel number

Madison County parcel IDs commonly use a format such as 02-00142.000. Use the number from the county record or tax statement rather than guessing it from an address.

1. Locate Parcel Number on the Advanced Search page.
2. Enter the identifier exactly as it appears, including applicable punctuation.
3. Select Parcel Search.
4. Open the matching parcel and review its details.

Search manufactured or mobile homes

The same official search page has a separate Mobile Home Search section, which includes fields for registration number, park name and lot number.

If a manufactured home cannot be found through the ordinary address search, use this separate section. Homes taxed as real property may be represented differently from homes on the manufactured-home tax list.

Search recent property sales

The Advanced Search tool allows searches by sale-date range, sale-price range, buyer name, seller name and valid-sale status. Additional filters include township, school district, neighborhood, acreage, year built, living area, bedrooms and bathrooms.

For example, if you are checking recent sales in London, choose the relevant township or location and limit the dates. For a house-value comparison, narrow the results further by approximate living area and property characteristics.

Do not assume every recorded transfer is a market sale. Family transfers, multi-parcel transactions and transfers without consideration can be unsuitable as comparable-sale evidence.

What Information Is Included in a Madison County Property Record?

The county’s parcel records contain more than an owner’s name. The available printable property details may include land and building values, acreage, school district, tax district, sale history, tax balances, building characteristics and improvements.

Appraised value versus assessed value

Ohio real estate is generally assessed at 35% of appraised market value for tax purposes. A property appraised at $240,000 would ordinarily have an assessed value of $84,000 before the tax calculation and applicable reductions.

That does not mean the tax bill equals $84,000, or 35% of the property price. The bill depends on the applicable tax district, effective tax rates, voter-approved levies, credits and special assessments.

What if the county property details are wrong?

If the record shows the wrong square footage, incorrect number of buildings or another factual error, write down the parcel number and gather evidence such as an appraisal, survey, building records or photographs.

Contact the Auditor at 740-852-9717 to ask about correcting the information. A data correction may require a different process from a formal Board of Revision value complaint.

Madison County 2026 Revaluation: What Property Owners Need to Know

Madison County is conducting a full real estate reappraisal for tax year 2026. The Auditor announced that the countywide reappraisal has been completed and that tentative parcel values appear in the top line of the Valuation section of the official property records.

This is particularly important if you are comparing a 2025 value with a tentative 2026 value. A change in market value does not necessarily cause the same percentage change in property taxes.

How to review your tentative 2026 value

1. Search for your parcel.

   Open the official Auditor property search.

2. Open its Valuation section.

   Find the new tentative value indicated by the county.

3. Compare the prior appraisal.

   Note the earlier market value, new value and percentage difference.

4. Review recorded property characteristics.

   Check acreage, square footage, buildings, improvement details and property classification.

5. Look at appropriate sales.

   Use recent comparable sales as context, considering location, condition, age and size.

6. Contact the Auditor about errors.

   Keep evidence and ask about available review procedures and the formal complaint period.

When will the updated values affect taxes?

The 2026 valuation concerns tax year 2026, generally payable in 2027. Tax rates, levy results and other adjustments also influence the eventual bill.

As of October 29, 2026, the official tax estimator is still labeled for 2025 taxes payable in 2026. The county expects an update using 2026 rates after those rates are certified, around mid-December 2026.

Madison County GIS Map and Parcel Boundaries

A GIS parcel map can help you find a property visually, identify nearby parcels, review general acreage and understand where land sits in relation to roads and surrounding properties.

The Auditor’s official website provides a MAP navigation link to its GIS Parcel Viewer.

How to find land using the GIS viewer

1. Locate your parcel number.

   Use the property search first if you only know an address or owner.

2. Open the Auditor homepage.

   Visit auditor.co.madison.oh.us and select MAP.

3. Search for your property.

   Use the available parcel or location tools in the GIS viewer.

4. Examine the mapped parcel.

   Compare nearby roads, parcel outlines and surrounding properties.

5. Check legal records if necessary.

   For boundary dimensions, easements or ownership disputes, consult recorded legal descriptions and a licensed surveyor.

This is useful for rural acreage near Mount Sterling, land outside London and parcels in developing parts of the Plain City and West Jefferson areas.

Madison County Property Taxes: Bills, Payments and Due Dates

The Auditor provides appraisal, valuation and tax-history information. The Madison County Treasurer, currently Stacey L. McKenzie, handles real estate tax collection and payment questions.

2026 Madison County property tax due dates

The regular 2026 installment dates have passed. If you still owe taxes, contact the Treasurer to confirm your current balance, penalties and available payment arrangements.

How to pay Madison County property taxes

1. Find your tax account.

   Keep the parcel number or tax bill available.

2. Open the Treasurer payment page.

   Visit official Payment Information.

3. Choose a payment method.

   The county offers card payments, checks, money orders and cash through applicable methods. Electronic payments may include processing fees.

4. Use the tax payment portal if paying online.

   The Treasurer links to its online payment cart.

5. Verify the parcel and amount.

   Check the tax period, outstanding balance and payment fees.

6. Keep proof of payment.

   Save a confirmation or receipt, particularly if a delinquency or transfer is involved.

Pay by mail or in person

Mail: Madison County Treasurer, 1 N Main Street, PO Box 675, London, OH 43140-0675. Include the tax bill stub with a check payable to the Treasurer.

In person: Treasurer’s Office, main floor of the courthouse, 1 N Main Street, London, Ohio. Published hours are Monday–Friday, 8 a.m.–4 p.m., excluding federal holidays.

After-hours drop box: The Treasurer lists a white night deposit box on the west side of the courthouse facing Main Street.

Penalties and late tax payments

The Treasurer’s published instructions describe a 5% penalty on unpaid taxes during the first 10 days after the due date and a 10% penalty afterward, subject to applicable rules. Interest assessments are associated with July 1 and December 1.

For a specific account, always confirm the actual penalty with the Treasurer rather than calculating it yourself. The published returned-check charge is $13.

Treasurer phone: 740-852-1936 or 877-454-3309 from within Madison County.

Can taxes be deducted automatically?

Yes. The Treasurer offers an automatic bank withdrawal arrangement. Its published form allows several payment schedules, including full-year or half-year deductions and a monthly option.

Download the Automatic Withdrawal Agreement PDF, complete the owner, property, parcel and banking details, select a schedule, sign it and return it with a voided check as instructed.

Because the form contains sensitive banking information, send it only through the Treasurer’s approved submission method. Do not email account details to an unverified address.

Estimate Madison County Property Taxes Before Buying a Home

A property-tax estimate is especially valuable for homebuyers. Two houses with similar prices can have different tax bills because they belong to different school or taxing districts, or qualify for different reductions.

How to use the official tax estimator

1. Open the Madison County Tax Estimator.

   The current calculator is labeled 2025 Tax Estimator.

2. Enter the property’s appraised value.

   Use a reasonable figure for the calculation and ensure you are entering market value rather than the assessed value.

3. Select the tax district.

   Choose the district corresponding to the property’s actual location.

4. Select the property type.

   Available categories include residential, agricultural and commercial/industrial.

5. Choose applicable reductions.

   Indicate owner-occupancy or Homestead treatment only where the property qualifies.

6. Choose Compute.

   Read the estimated amount and remember that it is not a guaranteed future bill.

Important for 2026 buyers: The current calculator estimates tax year 2025 amounts payable in 2026, not the final impact of the new 2026 reappraisal. The county says updated 2026 tax rates are expected around mid-December 2026 following state certification.

For buyers, review the current tax bill, the property’s new 2026 valuation and whether existing credits will continue. Your title company can also help explain tax prorations at closing.

Madison County Homestead Exemption and Owner-Occupancy Credit

Qualified homeowners may be eligible for property-tax relief through Ohio’s Homestead Exemption or Owner-Occupancy Credit. These programs have separate eligibility requirements.

Homestead Exemption eligibility

Standard Homestead relief is available under applicable Ohio rules to qualifying older homeowners, permanently and totally disabled individuals and certain surviving spouses. Enhanced or separate provisions may apply to qualifying disabled veterans and surviving spouses of public service officers killed in the line of duty.

Income requirements depend on the applicant’s category, tax year and applicable law. The Auditor’s October 2026 announcement identifies a $41,000 Ohio adjusted gross income threshold for certain applicants seeking the special credit through Homestead eligibility verification. Do not assume that one threshold applies to every Homestead category.

How to apply for Homestead

1. Check eligibility.

   Review your age or disability status, ownership, principal residence and applicable income requirements.

2. Open the official Madison County Auditor Forms page.

   Find the Tax Reduction section.

3. Choose the proper application.

   DTE 105A is listed for seniors, disabled persons and qualifying surviving spouses. DTE 105I and DTE 105K address certain other eligible categories.

4. Gather supporting documents.

   Depending on the application, documents relating to residence, income, disability, veteran status or surviving-spouse status may be needed.

5. Complete and sign the form.

   Use the appropriate application-year information and follow the instructions for any required certification.

6. Submit to the Auditor.

   Use the official submission method and confirm the applicable filing cutoff.

Owner-Occupancy Credit

The owner-occupancy reduction is a separate benefit for qualifying principal residences. Owning a house does not automatically establish eligibility: a rental home or second residence may be treated differently.

The county lists DTE 105C and DTE 105D among its owner-occupancy tax reduction forms. Review the specific instructions before applying.

After buying a home, check whether the Auditor record properly reflects your principal-residence status. A seller’s exemption or credit should not be assumed to continue automatically for the buyer.

How to Challenge a Madison County Property Valuation

If the Auditor’s estimated market value seems incorrect, the first step is to understand the difference between a factual error and a disagreement about market value.

The Madison County Board of Revision is the formal local process for qualifying property valuation complaints. It reviews evidence about value, not simply whether the property tax bill feels unaffordable.

Steps for a Board of Revision complaint

1. Locate the property record.

   Note the parcel number, tax year and valuation being disputed.

2. Collect relevant evidence.

   Consider an appraisal, recent arm’s-length sales, purchase documents, photographs of damage, repair estimates and verified property-characteristic differences.

3. Get the correct form.

   The Auditor Forms page lists DTE 1 for complaints against real property valuation, as well as Board of Revision rules.

4. Complete the complaint.

   State the parcel, the value at issue, the value you believe is supported and the reasons for your request.

5. Submit within the applicable period.

   Ohio’s regular real-property valuation complaint window generally runs from January 1 through March 31 for the relevant tax year. Confirm the county’s instructions and any exceptions.

6. Prepare for review.

   Follow hearing notices, evidence submission requirements and Board procedures.

The county’s form listing includes an email submission instruction for DTE 1. Use the address and method shown on the actual form listing, rather than an email copied from an unrelated website.

What evidence is useful?

A Board of Revision decision may increase or decrease valuation depending on the evidence and applicable law. Do not file assuming a reduction is guaranteed.

Damaged property deduction

If a house or building was destroyed or significantly damaged, a separate process may apply. The Auditor’s forms library lists DTE 26 — Application for Valuation Deduction for Destroyed or Damaged Real Property.

Gather dated photographs, insurance information, repair estimates and the relevant incident date. Contact the Auditor for the correct filing deadlines and applicable deduction rules.

Madison County CAUV: Agricultural Land Valuation

Madison County includes substantial agricultural land. The Current Agricultural Use Value (CAUV) program can provide qualifying landowners with a valuation based on agricultural productivity rather than a property’s ordinary development-market potential.

CAUV does not automatically apply to every rural parcel. Agricultural use, acreage, farming history and income conditions matter.

General CAUV eligibility

Ohio’s CAUV framework generally includes land of at least 10 acres devoted exclusively to qualifying commercial agricultural use, and certain smaller agricultural parcels meeting the required gross-income test. Specific rules also apply to qualifying woodland and other agricultural situations.

For parcels under 10 acres, Ohio generally uses an average annual gross agricultural income threshold of $2,500, subject to the statutory rules and application circumstances.

How to apply for CAUV

1. Find your agricultural parcel.

   Use the Auditor’s property search to confirm acreage, ownership and existing classification.

2. Review the land’s agricultural activity.

   Determine whether its use meets the applicable commercial agricultural requirements.

3. Open the Agricultural Use forms.

   Locate DTE 109, the initial CAUV application.

4. Complete the application.

   Provide the required land-use information and supporting details.

5. Submit within the filing period.

   Confirm the county’s current application deadline and submission instructions.

6. Continue qualifying use.

   Enrolled owners should follow annual renewal requirements and respond to DTE 109A as required.

What happens when agricultural land is converted?

Land removed from CAUV or converted to nonqualifying use may be subject to recoupment charges under Ohio law. A sale does not necessarily eliminate these issues.

The county lists DTE 102 for conveyance of CAUV property and DTE 115 for certain recoupment deferral applications. Agricultural district applications are also available through form ODA 11.

If you are planning a land split, residential development or a sale of agricultural acreage, discuss the CAUV implications with the Auditor before completing the transaction.

2026 agricultural valuation information

The Auditor’s information section provides a current CAUV values publication and a 2026 CAUV update slideshow. These resources can explain the agricultural valuation process and the year’s changes.

Visit General Information and find the CAUV/Ag District section.

Madison County Deeds, Ownership Transfers and Conveyance Fees

The Auditor’s property record can show owner and transfer information, but it is not a replacement for a recorded deed.

The Madison County Recorder maintains the official land-record documents. For ownership verification, recorded easements, mortgages and deed copies, use the Recorder’s records rather than relying solely on the Auditor’s property card.

How to find a deed online

1. Find the property in the Auditor database.

   Copy the listed owner, parcel number and relevant sale details.

2. Open the Madison County Recorder Official Land Records Search.

   Choose the system’s Search option.

3. Search available recorded information.

   Use owner names or the record-search fields supported by the system.

4. Compare the results.

   Check the document type, grantor, grantee, date and legal description.

5. Request copies if required.

   The Recorder instructs users to contact its office for certified document copies.

Recorder: Rachel Fisher. Office: 1 N Main Street, Room 40, London, OH 43140. Phone: 740-852-1854.

Madison County conveyance and transfer fees

The Auditor publishes the following fee structure:

Example: Conveyance fee on a $250,000 sale

At $3 per $1,000, the conveyance fee for a $250,000 taxable transaction is $750. If one parcel is transferred, the listed parcel transfer charge adds $0.50, for an estimated $750.50 before any other applicable recording or transaction costs.

This is an example, not a final closing statement. Transfers claiming exemptions or involving several parcels can differ.

Use the official conveyance calculator

1. Open the Madison County Conveyance Fee Calculator.
2. Enter the number of parcels being transferred.
3. Enter the sale price.
4. Select Compute.
5. Review the estimate, which includes the parcel transfer fee.

The Auditor’s forms include DTE 100 for applicable conveyances and DTE 100EX for claims of exemption from the conveyance fee. Other documents may be required for manufactured homes, CAUV land, Homestead property and trustee transactions.

Dog Licenses, Vendor Forms and Other Auditor Services

Madison County dog licenses

Ohio generally requires dogs older than three months to be licensed. Madison County offers one-year, three-year and permanent dog tags.

The standard annual licensing period is December 1 through January 31. Late applications may be subject to penalties, and online purchases have a listed minimum convenience fee of $2.50 per tag.

How to buy or renew a dog tag

1. Visit the Auditor’s General Information page.
2. Find the Dog Tags section.
3. Select the online ordering option or download the Dog Registration Application.
4. Enter the owner’s name, address and required dog details.
5. Choose the available license duration.
6. Review the license price and applicable convenience fee.
7. Complete the purchase and retain the registration information.

Madison County also lists authorized local vendors. These include Dwyer Brothers and Sheffield Veterinary Hospital in London; Reiterman Feed and Supply in Mount Sterling; several locations in West Jefferson; and Plain City Animal Hospital and Plain City Ace Hardware.

Participating vendors may have different payment restrictions. The county lists a $1 convenience charge at these vendors and marks several as cash-only. Check availability before visiting.

Dog tag owner search

The Auditor provides a Dog Tag Owner Search. Its information page also explains an optional dog-photo feature that may help identify a lost pet.

To add a photo, follow the county’s published instructions, including the required JPEG image and tag number. Do not publish someone else’s personal information or use the tag lookup for unrelated screening purposes.

Vendor licensing and weights and measures

The Auditor’s forms library includes a Vendor’s License Application for Taxable Sales, an Ohio sales tax collection chart and a Retail Cigarette License Application.

For businesses using commercial weighing or measuring devices, the Auditor also has weights-and-measures responsibilities. Its public information includes consumer guidance such as Firewood Facts.

Visit official Forms and select the relevant category. Confirm current state rules and fees before applying.

Download property and GIS data

For researchers and businesses working with larger volumes of property information, Madison County lists CAMA data downloads in spreadsheet and XML formats, along with GIS data resources.

These are available from the Data Downloads section. Read the county’s data limitations and update information before using exported records in analysis.

Madison County Auditor Office: Address, Phone and Hours

The Auditor’s Office is in London, Ohio. For a time-sensitive submission or a question about a specific parcel, have the parcel number and relevant documents ready when calling.

Get directions to the Madison County Auditor’s Office

The Treasurer and Recorder are located in the courthouse complex, but their departments handle different tasks. Confirm which office you need before making the trip.

Other useful Ohio property resources

Owners of property in nearby counties must search the Auditor responsible for that county. For example, use the Franklin County Auditor guide for Franklin County property records, the Union County Auditor guide for Union County parcels, or the Clark County Auditor guide for Clark County services.

Our Ohio county auditor directory can help you find the correct county office when a town or postal address overlaps county boundaries.

Madison County Auditor: 10 Frequently Asked Questions

What to Do Next

For a Madison County property question, begin with the correct parcel. The owner’s name, property valuation, tax district, sale history and building details will usually tell you which service you need next.

If your question concerns the 2026 reappraisal, review the new tentative value and compare it with your property’s recorded characteristics. If you need to pay taxes, contact the Treasurer. For deeds, use the Recorder. For Homestead, CAUV or valuation complaints, follow the Auditor’s applicable forms and deadlines.

The most useful preparation is simple: keep your parcel number, relevant tax year and supporting documents available before starting an application or calling a county office.
