Montgomery County County Auditor, OH: Property & Tax Records (2026)

Montgomery County Auditor Property Search: Address, Owner and Parcel Number

The county’s official property lookup is MCRealEstate. It provides public access to real estate information maintained for Montgomery County, Ohio.

For most homeowners, the fastest way to find the correct record is to search using the street address. If you are researching an investment property, inherited property or vacant lot, an owner name or parcel number may work better.

Search a property by address

1. Open MCRealEstate.

   Visit the official Montgomery County property-search system.

2. Select the address search.

   Choose the address-based search option displayed by the portal. Begin with the house number and primary street name.

3. Enter a shorter address if needed.

   For example, when searching for a property on South Main Street, try the house number and “Main” first. Add the direction or suffix only if necessary.

4. Compare matching results.

   Make sure the parcel is in the correct municipality or township. Similar street names and multi-unit properties can produce confusing matches.

5. Open the complete parcel record.

   Review ownership, parcel identification, property description, values, sale information and available tax or mapping details.

Search by property owner’s name

Owner search can be helpful when you know a person’s name but not the address.

1. Open MCRealEstate and choose the owner-name search option.
2. Start with the last name rather than typing the entire name.
3. For businesses, try the important part of the company name before adding LLC or Inc.
4. Review each result and compare its location and parcel number.
5. Open the matching property record to confirm the listed owner.

A property owned by a trust, estate, partnership or limited liability company may not appear under the name of the person you expected.

Search by parcel ID

A parcel identification number is generally more precise than a street address. It can be especially useful for undeveloped land, agricultural parcels and properties without conventional house numbers.

Find the parcel number on a previous property-tax statement, closing document or existing county property record. Enter it in the portal’s parcel-search field and verify the resulting location.

Why is my property not showing up?

Common reasons include misspelled street names, address-format differences, ownership recorded under a business name, a recent parcel split or a property without a standard street address.

Try fewer search terms. Remove punctuation, street suffixes and apartment numbers. If needed, search by owner or use the GIS map to identify the parcel visually.

How to Understand Your Montgomery County Property Record

Once you open a property in MCRealEstate, several values and descriptions may appear. Understanding the difference between them helps avoid mistakes when reviewing taxes, buying property or considering an appeal.

Appraised value versus assessed value

Ohio real property is generally assessed for taxation at 35% of its appraised market value.

For example, consider a home with a county appraised value of $200,000:

The assessed value is not your annual tax bill. Actual taxes depend on the property’s taxing district, effective levy rates, reduction factors, exemptions, credits and special assessments.

Montgomery County Property Taxes: Search, Payment and Delinquent Bills

The Auditor and Treasurer work with the same property-tax system, but they have different responsibilities.

The Auditor maintains valuations and real estate assessment information. The Treasurer collects property taxes, processes payments and handles payment-related questions.

How to check and pay property taxes

1. Find your property in MCRealEstate.

   Confirm the correct parcel ID and property address. Review the tax-related details shown in the record.

2. Open the official Treasurer page.

   Visit Montgomery County Pay Your Taxes.

3. Select the payment method.

   Choose the online payment option or review alternative payment instructions.

4. Verify the account and balance.

   Confirm the parcel, payment amount, installment and any displayed penalties or processing charges.

5. Complete payment and save proof.

   Keep the receipt or confirmation number. Allow time for the payment to appear in the county account.

What if my property taxes are overdue?

Open the Treasurer’s tax information and check whether the balance includes delinquent tax, penalties or interest. If you are unable to pay the entire amount, contact the Treasurer about available arrangements rather than assuming the account will automatically qualify for a payment plan.

Treasurer phone: 937-225-4010.

Does a higher property value mean an equally large tax increase?

Not necessarily. Ohio property taxes are affected by several rules, including voted and unvoted levies, effective tax rates, credits and special assessments.

A 20% increase in appraised value does not automatically create a 20% increase in the final tax bill.

To understand a change, compare your old and new values, the tax district, tax rates, credits and special assessments for the same parcel.

Montgomery County 2026 Property Reappraisal: New Values and Important Dates

This is one of the most important current topics for Montgomery County homeowners.

The Montgomery County Auditor is conducting a full property reappraisal in 2026. Ohio requires a full reappraisal every six years, with a market update in the intervening three-year period.

The county’s previous triennial market update occurred in 2023. The 2026 project reviews property characteristics and relevant real estate sales to establish updated values.

2026 reappraisal timeline

The new values are intended to affect property-tax bills paid in 2027, not the taxes paid during calendar year 2026.

How to check your new 2026 tentative value

1. Visit the county’s reappraisal page.

   Open 2026 Property Reappraisal.

2. Select the tentative-value lookup.

   The official page provides a link to view your new tentative property value.

3. Search the correct property.

   Use the available address or parcel search and confirm the property details.

4. Compare the old and new information.

   Review the property’s value, characteristics and any relevant sale information.

5. Investigate a questionable valuation.

   Use the county’s neighborhood sales viewer to compare nearby open-market transactions. Save relevant evidence for a potential Board of Revision complaint.

What sales does the Auditor consider?

The county generally looks for valid open-market sales between willing buyers and sellers. Transactions such as certain family transfers, foreclosure auctions, sheriff’s sales and multi-property transfers may not represent ordinary market conditions.

For a useful comparison, look for properties with similar location, size, age, condition and features. A very large, newly renovated home may not be a fair comparison for a smaller property needing significant repairs.

Open the official 2026 Neighborhood Viewer.

How to Appeal a Montgomery County Property Value

If you believe your property’s valuation is incorrect, the Montgomery County Board of Revision is the formal process for requesting a change.

The key is evidence. The Board does not simply lower values because a tax bill feels expensive. Your documentation should explain why the property’s appraised market value is inaccurate.

Property value appeal filing steps

1. Verify the property and tax year.

   Find your parcel in MCRealEstate and record the value you are disputing.

2. Gather supporting evidence.

   Useful documents may include an appraisal, recent open-market purchase, comparable sales, photos of damage or written repair estimates.

3. Open the Board of Revision resources.

   Visit the official Montgomery County Real Estate page and select Board of Revision. The county also publishes the complaint form in its Forms & Documents section.

4. Complete the valuation complaint.

   Use the applicable Complaint Against the Valuation of Real Property form, commonly DTE 1. Identify the parcel, requested valuation and supporting facts.

5. Submit during the allowed filing period.

   For the 2026 reappraisal values, the county identifies January through March 2027 as the appeal period. Follow the current instructions and filing deadline.

6. Prepare for a possible hearing.

   Keep copies of all submitted materials and respond to official notices. Be prepared to explain your evidence clearly.

Evidence that may strengthen your complaint

Arguments based only on a neighbor’s assigned value, a difficult financial situation or dissatisfaction with the amount of taxes are generally not enough to demonstrate an incorrect market valuation.

Board of Revision: 937-496-6856.

Montgomery County Auditor GIS Maps and Parcel Boundaries

The Auditor’s Geographic Information System is useful when you need to find a parcel visually, examine neighboring properties or understand a property’s approximate location and shape.

The official GIS page includes access to the county’s interactive parcel map and other mapping resources.

How to view a parcel on the GIS map

1. Open the official GIS page.

   Go to Montgomery County Auditor GIS.

2. Select Interactive GIS Map.

   Follow the county’s map link and allow the map to load.

3. Locate the property.

   Use the available search control or navigate to the property’s neighborhood.

4. Inspect the parcel.

   Review the displayed map layers, parcel shape and surrounding streets or properties.

5. Compare with the real estate record.

   Use MCRealEstate to verify parcel identity, owner information and related property descriptions.

What can GIS help you research?

• Approximate parcel locations and shapes.
• Nearby lots and adjoining properties.
• Street and neighborhood context.
• Parcel relationships relevant to property research.
• Mapping layers and other county geographic information where available.

Some users also need historical aerial photographs, elevation information or engineering-related maps. Montgomery County Engineer maintains separate GIS resources, including historical imagery and contour information.

Montgomery County Homestead Exemption and Property Tax Reductions

Montgomery County homeowners who meet certain age, disability, surviving-spouse or other statutory requirements may qualify for property-tax relief.

The Homestead Exemption reduces the taxable value of qualifying property under Ohio law. It is not a cash payment or a fixed refund for every homeowner.

Who may qualify?

• Qualifying homeowners age 65 or older.
• Homeowners who are permanently and totally disabled under applicable rules.
• Certain qualifying surviving spouses.
• Qualifying disabled veterans and other specially protected categories under Ohio law.

The standard income-tested program has a combined household income requirement for many new applicants. Montgomery County’s current published guidance identifies a $41,000 Ohio modified adjusted gross income limit using 2025 income for current applications, and $40,000 using 2024 income for certain late applications.

Income limits are adjusted under Ohio law, so confirm the applicable tax year and applicant category before filing. Some previous recipients and special categories are exempt from the standard means test.

How to apply for Homestead

1. Review the county’s Homestead guidance.

   Visit Montgomery County Homestead.

2. Identify your eligibility category.

   Check age, disability, income, ownership and principal-residence requirements that apply to your situation.

3. Download the application.

   Use the county’s official Homestead application (DTE 105A PDF) when appropriate, or select the special-category form listed by the county.

4. Complete the requested information.

   Prepare identifying details, property information, income information and any required disability or eligibility certification.

5. Submit the application.

   Follow the form’s filing instructions. The county lists mailing to the Auditor’s Homestead Department at 451 W Third Street, Dayton, OH 45422-1021.

6. Confirm the benefit.

   Retain a copy and review subsequent property records or tax bills to check that any approved reduction has been applied.

2026 one-time Homestead bonus credit

Montgomery County has announced a one-time additional Homestead credit of approximately $450–$500 under Ohio HB 479, intended for the first-half tax bill due in February 2027.

The county specified an October 23, 2026 deadline for first-time applicants seeking that additional credit. This deadline has passed. Homeowners already enrolled were told they did not need to reapply.

If you missed the special deadline, contact the Homestead Department to ask about ordinary eligibility and future tax-year applications rather than assuming all Homestead opportunities have ended.

Owner-occupancy credit

Ohio also provides a separate owner-occupancy property-tax reduction for qualifying homes used as the owner’s principal residence.

The commonly referenced 2.5% owner-occupancy credit is not the same as Homestead. Qualifying homeowners should review both independently.

The county forms collection includes the owner-occupancy tax reduction application.

Homestead Hotline: 937-225-4341.

Montgomery County CAUV: Agricultural Land Valuation

Current Agricultural Use Valuation (CAUV) allows qualifying Ohio farmland to be valued based on agricultural use rather than its development-market potential.

This program may provide substantial tax benefits for eligible agricultural property, but the owner must satisfy the statutory requirements and complete the necessary filing process.

Basic eligibility

Land devoted exclusively to qualifying agricultural use for the required period may be eligible. The rules generally distinguish between land with at least 10 qualifying acres and smaller agricultural operations that must satisfy applicable gross-income requirements.

Woodland, conservation-program acreage and certain agritourism activities can require additional review under the program’s definitions.

How to file a CAUV application

1. Find the parcel ID, ownership details and acreage.
2. Review the land’s agricultural use over the required prior years.
3. Download the appropriate initial or renewal application.
4. Complete the acreage, agricultural activity and income sections that apply.
5. Check the current filing deadline and any fee or supporting-document requirements.
6. Submit the completed application to the Montgomery County Auditor.

The county provides these official documents:

• DTE 109 — Initial CAUV Application (PDF)
• DTE 109A — CAUV Renewal Application (PDF)

The published form instructions generally require filing after the first Monday in January and before the first Monday in March, subject to specified exceptions. The application must be received by the applicable deadline, not merely postmarked.

What if agricultural use ends?

If qualifying land is converted to a nonagricultural use or otherwise loses eligibility, a recoupment charge may apply. The published CAUV forms describe recoupment based on tax savings over the previous three years.

Before selling, developing, subdividing or changing farmland use, ask the Auditor about the effects on CAUV status.

CAUV department: 937-496-3391.

Montgomery County Deed Transfers, Conveyance Fees and Ownership Changes

The Auditor’s deed-transfer process helps update county ownership and property records. The Recorder’s Office maintains recorded instruments such as deeds and mortgages.

If you are buying, selling, gifting or transferring real estate, both offices may be involved.

Official conveyance fee

Montgomery County publishes these charges for applicable real estate transfers:

• $3 per $1,000 of actual sale price as the conveyance fee.
• $0.50 per parcel as the transfer fee.

These calculations are examples for a single parcel subject to the standard stated fee. Exempt transfers, multiple parcels and additional recording charges can change the amount due.

Steps for a property transfer

1. Confirm the parcel information.

   Verify ownership, parcel numbers and legal descriptions before preparing the transfer.

2. Prepare the appropriate deed.

   Ensure the document meets the applicable legal and recording requirements. Seek professional assistance when necessary.

3. Complete the conveyance statement.

   Use the Real Property Conveyance Fee Statement of Value and Receipt or the applicable exemption statement.

4. Check the total fees.

   Include conveyance, parcel-transfer and separate recording charges where applicable.

5. Complete the county procedures.

   Follow the Auditor’s deed-transfer requirements and the Recorder’s recording procedure.

6. Check the updated public record.

   After processing, use MCRealEstate to confirm the new ownership information appears correctly.

Other Montgomery County Auditor Services

Not every visitor comes to the Auditor’s Office for a home valuation. Several other local services are handled through the same department.

Residential rental registration

Ohio requires owners of applicable residential rental property to register identifying and contact information with the county Auditor.

Montgomery County includes a Residential Rental Property Registration form in its official forms collection.

Property owners should review the registration requirements after purchasing or converting a property into a rental. If a responsible contact or ownership information changes, determine whether the registration must be updated.

Damaged or destroyed property

Serious fire, storm or other structural damage may qualify for a property-value adjustment under Ohio’s damaged-property procedures.

The county provides a Destroyed or Damaged Property form. Owners should document the date, nature and extent of damage, preserve photographs and repair estimates, and check the filing deadline that applies to the event.

Contact Real Estate Assessment at 937-225-4326 when unsure whether the issue requires a damage application or a separate valuation complaint.

Manufactured and mobile homes

Manufactured homes can have separate tax, title-transfer and conveyance procedures. The Auditor’s Homestead guidance explains that taxes on the home may need to be paid before a title transfer can proceed.

Montgomery County publishes conveyance fees for applicable manufactured-home transfers of $3 per $1,000 of the sale price plus a $0.50 transfer fee, with exemptions possible for qualifying transactions.

Dog licenses

The Auditor also handles dog registration.

The official county application currently displays:

• $20 for a standard spayed or neutered dog license.
• $24 for a standard unaltered dog license, subject to applicable exclusions.
• Online card processing of 2.3%, with a $2 minimum.
• Online electronic-check processing of $0.50.

Three-year and permanent tags are available through the Auditor’s Office or by mail rather than through the standard online transaction. Prices and eligibility vary by license type.

Dog licensing: 937-225-4314.

Vendor and cigarette licenses

Businesses may also need the Auditor for applicable vendor or cigarette-dealer licenses. Start with the official forms page and confirm whether your business activity requires a county-administered license.

Montgomery County Auditor Office: Address, Phone, Hours and Departments

Which department should you contact?

Before visiting in person

Bring the parcel number, property address and any applicable form, notice or supporting document. If your transaction involves payment, contact the office about accepted payment methods.

Auditor and Treasurer hours are not necessarily identical. The Treasurer’s published public hours are generally Monday–Friday, 8 a.m.–4 p.m.

For complicated property transfers, valuation complaints or filing deadlines, calling the relevant department before visiting can prevent an unnecessary trip.
