What is the Ohio property tax assessment ratio?

Ohio law sets taxable value at 35% of market (true) value statewide, under Ohio Revised Code §5713.03. Your county auditor must use this ratio when calculating your tax bill.

How much is the Ohio Homestead Reduction in 2026?

For tax year 2026, the general Homestead Reduction shields $29,000 of market value for qualifying owners age 65+, totally disabled, or surviving spouses age 59+ with Ohio Adjusted Gross Income under $41,000. The enhanced amount for 100% disabled veterans and surviving spouses of public-safety officers killed in the line of duty is $58,000 with no income limit. File DTE Form 105A with your county auditor.

When is the Ohio Board of Revision deadline?

Ohio's statutory Board of Revision (BOR) complaint deadline is March 31 for the prior tax year, per ORC §5715.19. Complaints are filed using DTE Form 1 with your county auditor at no cost. Late filings are rejected except in very narrow clerical-error circumstances.

How much is the Ohio real property conveyance fee?

Ohio's conveyance fee has two parts: a mandatory $1.00 per $1,000 state fee (ORC §319.54(F)(3)) and a permissive county levy of up to $3.00 per $1,000 (ORC §322.02). Most Ohio counties charge the full $4.00 per $1,000. A separate $0.50 transfer fee applies per parcel. Filed using DTE Form 100 at the auditor's office at closing.

Who qualifies for Ohio's CAUV agricultural tax break?

Ohio's Current Agricultural Use Value (CAUV) program lets actively farmed land be taxed on its agricultural value rather than its market value. Eligibility requires 10+ acres devoted exclusively to commercial agriculture, or smaller parcels with $2,500+ in gross annual income from agriculture. Apply using DTE Form 109 and renew annually with DTE 109A. Removing land from CAUV triggers recoupment of three years of saved taxes under ORC §5713.34.

Q: What happens if Dallas County property taxes are late?

Dallas County states that late interest accrues at 1.5 percent per month, rounded to the nearest dollar. Continued delinquency can eventually result in the parcel being offered at the county's annual tax sale.

Do not start with the wrong county office. The Dallas County Auditor maintains real-estate transfers, plat maps, transfer books and certified tax levies. The primary owner/address/property-value search belongs to the Dallas County Assessor.

Quick answer: where should you search?

For a normal Dallas County property lookup, start with the Assessor’s official Beacon search. Search the property, verify the parcel, save its district/parcel number and assessed value, then move to the Auditor for transfer or split/combine questions, Treasurer for payments, Recorder for deeds, or GeoDallas for advanced maps.

1 Search the property Start with address or another reliable parcel clue.

2 Verify the result Match address, deed holder and parcel number.

3 Save the record Keep assessment, tax district and sale information.

New construction is missing Search the land parcel or prior owner. Assessment reflects improvements based on their completion as of January 1.

Rural acreage is difficult to locate Use GeoDallas and search by address, owner, map number or subdivision.

Parcel was recently split Search the original parcel and contact the Auditor because the office processes parcel split requests.

Two parcels were combined Search the former numbers and ask the Auditor whether an administrative combination has been processed.

Old deed reference is missing Use the Recorder for current official land records and the Auditor’s historical COTT lookup for transfers, plats and deed information prior to November 1, 2023.

Why assessed value changes

Dallas County states that Iowa requires real estate to be reassessed every two years in odd-numbered years. Values can also change because of new construction, remodeling, additions, property condition, market supply and demand or other appraisal information.

Property facts worth checking

Finished versus unfinished basement
Living area and building dimensions
Bathrooms and remodeling
Garage, deck and additions
Property condition
New construction completion

Contact the Assessor when

A basement is incorrectly marked finished
A removed building still appears
Square footage appears incorrect
Property class appears wrong
An improvement is materially overstated
Record facts differ from actual conditions

Correction may require inspection: the county says an Assessor appraiser may need to walk through the property to obtain accurate data when assessment information is incorrect.

GeoDallas GIS

Use maps, aerials, subdivisions and parcel exports

GeoDallas provides more advanced mapping than a basic parcel result. The county says users can search by address, owner, map number or subdivision, view assessment and tax information, use aerial photography and create property lists for spreadsheet analysis.

GeoDallas micro steps

Identify the parcel in Beacon Copy the district/parcel or map information before opening GIS.

Open GeoDallas Choose the interactive mapping site or the relevant map resource.

Search using your strongest clue Use address, owner, map number or subdivision.

Verify the selected parcel Match the location and property information with the Assessor record.

Turn on useful layers Review aerial photography and surrounding parcel context as needed.

Create a property list when researching multiple parcels GeoDallas allows property lists to be imported into a spreadsheet for further analysis.

Survey warning: Dallas County expressly states that interactive maps do not represent a professional survey. The mapping is compiled from official records but can contain compilation errors. Use original recorded deeds, plats and surveys for legal boundary questions.

Recorded plat search

GeoDallas also provides a Plat Map Search for recorded subdivisions. The county warns that these documents represent the original recorded plat and later changes made by affidavit or another document may not appear on the original plat.

Sales and assessment research

Use sales data before questioning market value

The Assessor considers current market conditions and sales of similar property. Dallas County also publishes downloadable land-sale files for several property categories.

Agriculture

Agricultural land and building sale data can help with rural-market research.

Development and acreage

Separate files cover development land plus rural lots and acreages.

Commercial and urban lots

Commercial land sales and urban residential lot files are published separately.

Build a useful comparable set

Similar property class

Comparable location

Similar building size

Similar age and condition

Comparable acreage

Similar improvements

Recent market transaction

Normal rather than forced sale

Foreclosure warning: Dallas County says foreclosure transactions are considered forced sales and are not treated as normal sales for assessment purposes.

After deciding which property category matches your parcel, use the county’s official Sales Information page to download the relevant sale file.

Open official land-sale files

Recorded real-estate documents

Find deeds, mortgages, liens and certified copies

Use the Recorder when you need the actual recorded instrument. The Recorder maintains official real-estate documents and provides retrieval of those records.

Search the Recorder correctly

Assessment protest

Challenge assessed value—not the tax bill

2026 regular protest period has passed. Dallas County’s regular Board of Review filing period is April 2 through April 30 of the assessment year. Prepare early for a future filing instead of waiting for the last day.

The Board of Review only acts on assessed valuation. The county specifically says a petitioner must support why the valuation is excessive, inequitable or inadequate rather than simply arguing that the final property-tax payment is too high.

File during April 2–30 Dallas County accepts electronic petitions through the Assessor’s Beacon website or the designated Assessor email, as well as allowed mail, fax or delivery methods.

Check property-tax credits and exemptions

Current timing: the regular July 1 deadline for the 2026 assessment year has passed. Contact the Assessor about the next effective filing year rather than assuming a late application will reduce the current assessment.

Basic Homestead Credit and Exemption

Dallas County says the property must be the owner’s primary residence and the owner must live there for at least six months and one day of the year. A person can claim Homestead on only one property.

Online Homestead application micro steps

Open the property search Use the Assessor’s official Beacon application.

Enter the property address The county specifically says there is no need to enter anything else for this workflow.

Open the property result Confirm the correct deed holder and address.

Wait for a recent deed to post when necessary Dallas County says a recent buyer may not apply until the property appears under the buyer’s name as deed holder.

Age 65+ Homestead Exemption

To qualify for the age-based Homestead exemption, Dallas County says the eligible owner must be at least 65 years old on or before January 1 of the application year. The regular deadline is July 1.

Military Service Property Tax Exemption

A current or former active-duty service member must first bring an original or certified DD-214 to the Recorder for recording. An exemption application can then be filed with the Assessor. The regular deadline is July 1.

Ten practical answers

Dallas County Iowa property search FAQs

Where do I search Dallas County Iowa property records?

Use the Dallas County Assessor’s official Beacon property search. The County Auditor maintains real-estate transfer records, plat maps and transfer books, but the Assessor is responsible for property assessment and the primary parcel-search system.

Can I search Dallas County Iowa property by address?

Yes. Use the official Beacon property search and begin with the property address. If the exact address produces no result, remove unnecessary directions, unit information or extra wording and search more broadly.

Who handles property values in Dallas County Iowa?

The Dallas County Assessor determines real-property assessments. The assessment is effective January 1, and Iowa generally requires real estate to be reassessed every two years in odd-numbered years.

When are Dallas County Iowa property taxes due?

Dallas County property tax statements are mailed annually in August. The first half is due September 1 and becomes delinquent after September 30. The second half is due March 1 and becomes delinquent after March 31.

What happens if Dallas County property taxes are late?

Dallas County states that late interest accrues at 1.5% per month, rounded to the nearest dollar. Continued delinquency can eventually result in the parcel being offered at the county’s annual tax sale.

Are GeoDallas parcel boundaries legal survey lines?

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.
