Montgomery County Tax Assessment Search & Records

Montgomery County, Ohio · Assessment Search · Tax Records · 2026 Reappraisal

Find the Parcel, Check the Value, Fix the Next Problem

Use Montgomery County’s official property systems to search by owner, street address or parcel ID, then review appraised value, 35% assessed value, property characteristics, sales, taxes, special assessments, payment history and GIS links.

August 2026 is especially important: Montgomery County is completing its full reappraisal, tentative values have been mailed, and informal value-review meetings run through the end of August. This guide shows what to search, what the numbers mean, which evidence helps, and which county office controls the next step.

Get the quick answer Search assessment records Review your 2026 value
Verify the parcel ID and physical address before relying on a result. A same-name owner is not enough. Auditor assessment data, Treasurer payment records, Recorder documents and GIS maps answer different questions and can update at different times.

Quick answer: start with MCRealEstate

Use MCRealEstate for the parcel, owner, appraisal, assessment, land, buildings, sales, tax summary and GIS links. Use the separate Treasurer search when the question is the current balance, payment status, delinquency or a specific tax year.

1 Search one way Owner, simple address or parcel ID.
2 Open the parcel Confirm address and complete parcel ID.
3 Check the value Compare appraised and 35% assessed value.
4 Route the task Auditor, Treasurer, Recorder, GIS or BOR.

Assessment-review trick: before arguing about the dollar value, verify the underlying facts—living area, year built, condition, bath count, basement, outbuildings, land and recent sales. A factual record error can be more useful evidence than simply saying the tax bill feels high.
Assessment math

Appraised value and assessed value are not the same number

Ohio taxable assessment generally uses 35%

The county’s tax-bill guidance explains that appraised value is the property’s market value for tax purposes, while taxable or assessed value is 35% of that appraised value.

A $200,000 appraised value therefore corresponds to $70,000 of assessed value before tax rates, reduction factors, credits and special assessments are applied.

APPRAISED 100% market value ASSESSED 35% taxable value TAX DISTRICT Rates + levies CREDITS Reductions + Homestead NET BILL Plus assessments
A 20% value increase does not automatically mean a 20% tax increase. Montgomery County specifically warns that property taxes generally do not increase proportionately with value because effective rates, reduction factors, credits and the mix of levies matter.

The 2026 full reappraisal affects tax bills paid in 2027

Montgomery County is individually reviewing more than 250,000 real-estate parcels as part of the 2026 full reappraisal. Tentative values were mailed in July 2026. The county says those values will be used for taxing purposes beginning with tax bills paid in 2027—not the property taxes paid during calendar year 2026.

July 2026 Tentative values mailed

Compare the notice with the online parcel facts and recent sales.

July–August 2026 Informal reviews

Current opportunity to discuss the tentative value by Zoom or telephone.

Next phases Dec 2026 → Mar 2027

Final values go to the state in December; BOR appeal opportunity follows January–March 2027.

What evidence should you bring?

Recent open-market sale A sale of the subject property within the last three years can be highly relevant.
Recent appraisal The county identifies an appraisal within the last three years as useful evidence.
Comparable sales Use genuinely similar nearby properties, not merely the closest sale.
Condition photos Document structural or condition issues the property record may not reflect.
Repair estimates Support condition problems with specific costs where possible.
Property-data errors Bring evidence when square footage, baths, condition, improvements or other facts are incorrect.

Schedule an informal review

Find your parcel ID The scheduling portal says all parcel IDs begin with a letter.
Enter the parcel exactly Include the spaces as shown on the tax bill.
Add up to three parcels online The scheduling page allows up to three parcels for one informal review.
Call if you have more than three Use 937-224-8927 rather than trying to force additional parcels into the form.
Choose Zoom or telephone The county describes informal meetings as remote reviews.
Prepare evidence before the appointment Lead with the strongest objective evidence rather than a complaint about the tax bill.

2026 tax records and payment

Use the Treasurer for the current amount due

Both 2026 installments are now past. The county’s current FAQ lists February 13, 2026 for first half and July 24, 2026 for second half. An older official 2026 collection-timeline PDF still shows July 17 for second half. Because both dates have passed, use the live Treasurer record rather than calculating from an old bill or PDF.

If the account is already delinquent

Past-due payment plan

Monthly contracts may be available. If the contract remains in compliance, the county says additional penalties and interest are not added during the agreement.

More than one year past due

The county warns that property more than one year delinquent and not on a payment plan is subject to foreclosure and a tax lien.

Prepayment for current taxes

Current taxes must be paid to enroll in the regular prepayment program, and applications should be submitted at least 60 days before the due date.

Rental-property records

Residential rental registration is a separate owner obligation

Montgomery County states that Ohio requires residential rental owners to register qualifying rental property with the County Auditor. This can include one or more residential dwelling units, mobile-home parks and sites where spaces are leased for residential mobile/manufactured homes or RVs.

Use the parcel ID from the property record
Individual or sole proprietor: provide full owner name
Entity ownership: identify the entity and appropriate officer/contact
Out-of-state owners need an Ohio contact agent under the county’s guidance
Update registration information within 60 days of a change
Registration information is public record
Penalty risk: the county states that failure to provide required rental-registration information in a timely manner is a minor misdemeanor and may result in a penalty of up to $150 against the affected property.

10 practical answers

Montgomery County tax assessment FAQs

How do I search Montgomery County, Ohio property assessments?

Use the official MCRealEstate system. Search by owner name, property address or parcel ID, open the matching property and verify both the physical address and parcel ID before reviewing values, sales, taxes or GIS information.

How should I search an owner name in MCRealEstate?

Use LastName FirstName order. Start with the surname, then add the first name or initial if needed. The official search also supports the asterisk wildcard for partial-name searches.

Why does my Montgomery County address search return no property?

Remove the street direction and suffix. Enter the house number separately and use only the main street name. Try alternate forms such as 3rd versus Third and use a partial search when necessary.

What is the Montgomery County assessed-value percentage?

Ohio real property is generally assessed at 35% of appraised value. For example, a $200,000 appraised value corresponds to $70,000 of assessed value before tax rates, credits and special assessments are applied.

Will my tentative 2026 value change the taxes I pay in 2026?

No. Montgomery County states that the tentative 2026 reappraisal values take effect beginning in 2027 and affect property-tax bills paid in 2027. They do not change the property taxes paid during calendar year 2026.

What should I do if I disagree with my 2026 tentative value?

Schedule an informal review while the county’s July-August 2026 review period remains open. Useful evidence includes a recent open-market sale, an appraisal from the last three years, comparable sales, photographs, repair estimates and proof of incorrect property-record facts.

When were Montgomery County property taxes due in 2026?

The county’s current FAQ lists February 13, 2026 for first half and July 24, 2026 for second half. An older official collection-timeline PDF still shows July 17 for second half. Both dates have passed, so taxpayers should use the Treasurer’s live account for the current balance.

How do I check how much Montgomery County property tax I currently owe?

Use the Montgomery County Treasurer Real Estate Tax Information System. Select the tax year, complete one search field, open the matching Parcel ID and review the current charges, payments, penalties, interest and unpaid balance.

Who handles deeds in Montgomery County?

The Montgomery County Recorder handles deeds, mortgages, liens, releases, easements and recorded-document copies. Use the Auditor property record for parcel and transfer clues, then move to the Recorder when the actual recorded instrument is needed.

Can I use Montgomery County GIS parcel lines as legal boundaries?

No. Auditor GIS is useful for locating and researching parcels, but the county disclaims warranties concerning GIS accuracy. Exact boundary decisions should rely on deeds, plats and a professional survey when appropriate.

Verify with the official Ohio source

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.
