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.

Dallas County IA Property Search: Auditor, Assessor & GIS

Dallas County, Iowa · Assessor search, Auditor transfers, taxes, deeds and parcel maps

Find the Parcel—and the Right County Office

Looking for a Dallas County Auditor property search can be confusing because Iowa divides property work among several offices. The Assessor provides the searchable property-value database, while the Auditor maintains real-estate transfers, plat and transfer records and certifies tax levies.

Use this guide to find a parcel by address or owner information, understand its assessment, locate it on a map, check the upcoming tax bill, find the recorded deed, request a parcel split or combination, claim an exemption or prepare a future assessment protest.

Important Iowa distinction: If your goal is to search a property, confirm assessed value or correct building information, start with the Dallas County Assessor. Do not call the Auditor simply because the search phrase you used was “Dallas County Auditor property search.”

Quick answer: which property search should you use?

Use the official Dallas County Assessor Beacon property search for the parcel itself. Search by address or other available property information, open the matching property, confirm the parcel number and location, then use that parcel number when contacting the Auditor, Treasurer or Recorder.

1 Find the parcel Use the Assessor’s official Beacon search.

2 Verify the record Match parcel number, address and property characteristics.

3 Choose your task Value, transfer, tax, deed, plat or exemption.

Most important distinction

Assessor vs Auditor vs Treasurer vs Recorder

Dallas County’s property system is split among several elected or appointed offices. Using the wrong office is one of the biggest reasons a simple property task becomes frustrating.

Which Dallas County office handles each property task?
Your task	Correct office	What that office controls	Useful starting information
Search owner, address or parcel	Assessor	Property assessment database and value information.	Address, owner or parcel number.
Question assessed value	Assessor	Assessment data, appraisals and Board of Review process.	Parcel number, property facts and market evidence.
Real-estate transfer record	Auditor	Transfers, transfer books, plat maps and tax-levy certification.	Parcel number, buyer/seller and transfer date.
Split or combine parcels	Auditor	Administrative parcel split/combine requests and related real-estate records.	All existing parcel numbers and legal-description information.
Pay property taxes	Treasurer	Bills, collections, delinquency, tax sale and payment posting.	Parcel number and current statement.
Find deed or mortgage	Recorder	Official recorded deeds, mortgages, liens and other land documents.	Owner names and approximate recording date.
See property on a map	Assessor / GIS	Parcel-map search and geographical context.	Parcel number or property address.
Find original subdivision plat	Recorder / GeoDallas	Recorded plat documents.	Subdivision or plat name.

Fastest workflow: Find the parcel through the Assessor, copy its parcel number, then give that number to whichever office controls your next step.

Troubleshooting

No Dallas County property result found?

Full address returned nothing Use only the house number and main street word. Remove directional letters, suffixes and unit numbers.

Owner search failed Search only the last name, then try an alternate spelling, trust name, business or previous owner.

Property recently sold Search the seller’s name and then verify the recorded deed through the Recorder.

New construction Search the land or parent parcel. New improvements are valued according to their completion status on January 1.

Parcel was split Search the previous parcel number and ask the Auditor whether the administrative split has been completed.

Several parcels were combined Search each old parcel and check the Auditor’s combine-parcel records.

Mailing address differs The owner’s mailing address is not necessarily the physical property location.

Boundary location is unclear Use the map to locate nearby parcels, then verify boundaries with recorded documents or a survey.

How Dallas County assessments change

Iowa generally requires real estate reassessment every two years in odd-numbered years. That means 2026 is not the ordinary countywide reassessment year, but values can still be affected by new construction, improvements, corrections or other circumstances.

The assessment effective date is January 1. For new construction or improvements, the Assessor may determine a full or partial value based on the property’s state of completion on that date.

Incorrect property-card data? Dallas County specifically says owners should contact the Assessor when information such as a finished basement is wrong. An appraiser may need to inspect the property to verify the correction.

What can change value?

Garage or addition

Deck or exterior improvement

Kitchen or bathroom remodeling

Finished basement

Condition change

Comparable-property sales

Market supply and demand

Correction of inaccurate property data

Foreclosure-sale warning: The Assessor explains that foreclosure transactions are forced sales and are not treated as ordinary market sales for assessment purposes.

Current August 2026 action

Watch for the new property-tax statement

Dallas County’s tax calendar says new fiscal-year property-tax and special-assessment statements are mailed in August. As of August 7, 2026, the next normal payment deadline is the first-half installment due September 1.

Current period August 2026

New annual statements are mailed.

First half due September 1

Becomes delinquent after September 30.

Second half due March 1

Becomes delinquent after March 31.

No statement received? Contact the Treasurer Property Tax Division at 515-993-5808. Not receiving a paper statement should not be used as a reason to miss the deadline.

Online credit card	2.25% service fee	Confirm parcel and amount before authorizing the processor fee.
Online e-check	$0.25 service fee	Double-check routing and account numbers.

In-person debit card	$2 fee	Debit-card acceptance is listed for in-office use.
Drop box	Outside the Administration Building at 800 Court Street.	Use an identified payment envelope and do not leave cash.

Mailing detail that matters: Dallas County says a business-metered date or the date written on your check is not proof of timely mailing. The U.S. Postal Service postmark is the recognized mailing date.

Returned check: The Treasurer’s current payment page lists a $30 service charge for a check returned for insufficient funds.

Micro steps for online payment

Find the exact parcel Use the Assessor search and save its parcel number.

Open the Treasurer payment information Follow the county link to the Iowa Treasurer payment service.

Confirm owner, location and balance Do not pay a same-name parcel.

Choose full, scheduled or recurring payment The county says online users may set up full payments, scheduled payments or monthly recurring payments.

Tax calculation help

Estimate taxes without using the wrong value

The assessed value on a property card is not simply multiplied by a single countywide tax rate. Iowa property-tax calculations can involve assessment limitations or rollback factors, exemptions, credits and the levy rate for the parcel’s specific tax district.

Open the parcel Search by address and confirm the correct property.

Find its assessed value Confirm the assessment year.

Use the parcel’s actual taxing district Do not copy a levy rate from a nearby property.

Use Beacon’s Tax Estimator Dallas County says users can search the address and choose “tax estimator” from the maroon menu.

Check exemptions and credits Homestead, age-related or military benefits can change taxable value or the final bill.

Compare with the Treasurer statement An estimate is planning information, not the official amount due.

Do not copy the county’s sample levy rate into your calculation. Dallas County explicitly notes that levy rates vary by taxing district.

Read official tax-calculation help Open parcel search and estimator

Open the map search Use the parcel number or property information to locate the tract.

Check neighbouring parcels This helps distinguish similarly addressed or commonly owned tracts.

Compare the map with the record Make sure the parcel ID and physical location agree.

Use GeoDallas for recorded subdivision plats Search the subdivision or plat name when you need the original recorded plat.

Move to recorded documents or a survey when precision matters Do not use an online line for construction or a boundary dispute.

Recorded-plat warning: Dallas County says the plat-map site represents the original recorded plat. Later changes made by affidavit or another method may not appear there.

Boundary decision? Use the deed, later recorded documents and a professional survey rather than measuring from the online map.

Open official parcel map Search recorded plat maps

Official land documents

Find deeds, mortgages, liens and certified copies

The Assessor database helps identify a parcel, but the Recorder maintains the official real-estate documents. Use the Recorder when you need the deed, mortgage, release, real-estate lien or another recorded instrument.

Search recorded documents step by step

Copy parcel and ownership clues Save the current owner, prior owner and approximate transfer date from the property record.

Open the Recorder’s Online Record Search Use the official search linked from Dallas County’s Recorder page.

Search names in both directions Try current owners, previous owners, trusts and business entities.

Narrow by date or document type Use deed, mortgage, lien or other document categories when supported.

Compare legal-description clues A matching surname alone is not enough to prove the document belongs to your parcel.

Order a certified copy only when required Ask the receiving lender, court or agency whether a regular copy is sufficient.

Major 2026 change

Iowa Homestead changed for assessment year 2026

Beginning with assessment year 2026, Iowa’s previous Homestead Credit was replaced with a Homestead Tax Exemption. This is a significant change for Dallas County homeowners and older articles may describe the former credit instead.

Base exemption

10% of the taxable value of the homestead.

Published range

Minimum $5,500 and maximum $20,000 of taxable value, subject to annual inflation adjustment.

Age 65+

The current form states qualifying owners age 65 or older may receive an additional $6,500 taxable-value exemption.

July 1 filing timing

The current form states that a claim timely filed by July 1 of the assessment year applies to the corresponding assessment. For example, a claim filed by July 1, 2026 applies to assessment year 2026 and taxes due in September 2027 and March 2028.

July 1, 2026 has passed. If you did not file, contact the Assessor instead of assuming the exemption will appear automatically. Ask when a new claim would become effective.

Information the application asks for

Parcel number

Owner names and birth dates

Property location

Owner mailing address

Ownership type

Evidence of ownership

Date occupancy began

Previous residence information

Military exemption path: Dallas County says an original or certified DD-214 can be recorded with the Recorder. An exemption application may then be filed with the Assessor.

Contact the Assessor about exemptions Review military-record requirements

Auditor real-estate functions

Change an address, split parcels or combine parcels

This is where the Auditor becomes central to the property workflow. Dallas County’s Real Estate & Tax Inquiry resources include forms for mailing-address changes, parcel combinations, parcel splits, drainage repairs and subdivision plat-name approval.

Dallas County Auditor real-estate actions
Need	Official action	Prepare first
Tax statement mailing address is wrong	Real Estate Mailing Address Change	Parcel number, owner name, old address and new mailing address.
Combine adjoining tax parcels	Request to Combine Parcels	Every parcel number, common ownership details and reason for the request.
Divide property	Request to Split Parcels	Existing parcel number, legal-description and plat or survey information when applicable.
Drainage repair	Request for Drainage Repairs	Property identification and drainage problem details.
Name a subdivision plat	Subdivision Plat Name Approval	Proposed subdivision name and platting information.

Platting involves more than one office

Dallas County’s platting worksheet identifies Auditor approval of the subdivision name as one part of the Iowa platting process. Depending on the project, final plats, Planning and Zoning acceptance and Recorder submission requirements may also apply.

Do not create a legal description from the GIS map. A map label or parcel outline is not a substitute for a properly prepared legal description, survey or recorded plat.

Auditor transfer call script “I am working with parcel [parcel number] and need to [change the mailing address, split, combine or process a plat]. Can you confirm the current form, supporting documents and whether another county office must review it first?”

After identifying the exact administrative task, use the Auditor’s Real Estate & Tax Inquiry page. It also links older transfer, plat and deed lookup information for records prior to November 1, 2023.

Delinquent property warning

What if the property has older unpaid taxes?

Dallas County conducts an annual tax sale for qualifying delinquent parcels. The 2026 tax sale was held June 15, 2026. Tax sale does not mean a bidder immediately takes possession of the house; Iowa tax-sale and redemption rules control what happens next.

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.
