Jurisdiction correction: Dearborn County is in Indiana, not Ohio. In Beacon, select Indiana and then Dearborn County, IN. Do not use Ohio tax rules, forms or assessment terminology for this property.

Quick answer: where should you start?

Use Beacon for the property card and parcel map. Use the Assessor for assessed-value questions and appeals, the Auditor for deductions, ownership transfers and tax calculations, the Treasurer for bills and payments, and the Recorder for deeds, mortgages, liens and recorded documents.

1 Search broadly Use one surname, simple address or parcel ID.
2 Open the parcel report Select the blue 18-digit parcel number.
3 Verify two facts Match parcel ID and physical location.
4 Route the next task Assessor, Auditor, Treasurer or Recorder.

Failed-search recovery

No Dearborn County property result found?

Owner search returned nothing Use the surname alone, then try a former owner, trust, estate, business or alternate spelling.
Address search failed Keep the number and main street word but remove the direction, suffix, punctuation and unit.
Recent purchase Search the seller and check the Recorder’s Doxpop index for the new deed.
New construction or parcel split Search the developer, parent parcel, original acreage owner or nearby parcels on the map.
Mailing city is misleading Verify the map location and taxing district instead of relying only on the postal city.
Old parcel number stopped working The parcel may have been divided, combined or renumbered after a transfer.
Property is a mobile home The Treasurer may maintain mobile-home tax and permit records separately from ordinary real estate.
Property may be across the state line Dearborn County borders Ohio and Kentucky. Confirm the parcel is legally in Indiana before continuing.

Why assessed value and the final bill differ

The Assessor establishes the property assessment. The Auditor applies deductions and calculates taxes using certified rates. The Treasurer mails and collects the resulting bill.

Assessor question

“Is the property’s gross assessed value or factual record correct?”

Auditor question

“Are the deductions, transfer record, tax rates or calculation correct?”

Treasurer question

“What is currently due, and has my payment posted?”

Do not compare bills from assessment alone. Two properties with similar gross assessments can have different deductions, districts, tax caps, special assessments or delinquent balances.

Micro steps for online payment

Find the parcel number first Use Beacon or the current tax statement.
Check for escrow payment Confirm whether a mortgage company already paid or scheduled the bill.
Open the county-authorized payment portal Use dearborn-indiana-tax.com rather than an advertisement or unofficial payment page.
Match the parcel and owner Confirm the 18-digit parcel ID and property location.
Review the payment amount and fee Compare card and e-check costs before submitting.
Submit before 11:59 p.m. on the deadline Electronic payments submitted after that time are considered late.
Save the receipt Keep the confirmation, payment date, amount and parcel number.
Verify posting Recheck the account and call the Treasurer when the payment does not appear.

Late-payment penalty rules

Current published rule: A 5% penalty applies during the first 30 days after the deadline when there are no prior delinquencies. A 10% penalty applies after 30 days. When prior delinquencies exist, the county states that a 10% penalty applies immediately after the deadline.
Ignore old payment brochures when fees conflict. An older county GIS brochure mentions a prior PayGOV fee structure. The current Treasurer payment page lists the 2.25% card fee and $0.65 e-check fee used in this guide.
Treasurer call script “I am calling about parcel [18-digit number] at [address]. Please confirm the current amount due, whether the spring installment is delinquent, the penalty applied, whether any payment has posted and the safest payment method before November 10.”

Assessment review and appeal

The 2026 assessment-appeal deadline has passed

Published 2026 timeline: The county mailed 2026-pay-2027 Form 11 assessment notices on April 24, 2026. The published deadline for Form 130 and Form 134 was June 15, 2026. Contact the Assessor immediately if you missed the deadline or never received the notice.

An assessment appeal concerns the property’s assessed value or factual assessment record. It is not the correct process for disputing a payment posting, missed deduction or tax rate.

Delinquency and tax-sale protection

Act before a delinquent parcel reaches tax sale

The Treasurer certifies eligible delinquent property to the Auditor on or before July 1. The Auditor maintains the tax-sale eligibility list.

Published eligibility rules

Delinquent taxes or special assessments from the prior spring installment or earlier
Unpaid costs from a prior tax sale
Qualifying delinquency exceeding $25
Certification by the Treasurer to the Auditor
Full-payoff warning: A certified property generally cannot be removed from the tax-sale list until delinquent taxes, special assessments, penalties, interest and tax-sale costs are paid in full. The county may accept partial payments, but partial payment alone does not necessarily remove the parcel.

What to do immediately

Find the parcel and tax account Save the parcel number and owner information.
Call the Treasurer for the current payoff Ask for taxes, penalties, interest, assessments and costs.
Ask whether the parcel was certified Determine whether the account is already on the Auditor’s tax-sale list.
Do not assume partial payment protects the property Ask what amount and deadline are required for removal.
Use certified or approved payment when instructed Confirm accepted payment type before traveling or mailing funds.
Obtain written proof Keep the payoff statement, receipt and confirmation of removal when applicable.

Ten practical questions

Dearborn County property search FAQs

Is Dearborn County in Ohio or Indiana?

Dearborn County is in Indiana. Its county seat and property offices are in Lawrenceburg, Indiana. Property searches should use Dearborn County, IN in Beacon.

Where can I search Dearborn County property records?

Use the Dearborn County Beacon property search linked by the county. It supports searches by owner name, property address or 18-digit parcel number.

Is the Dearborn County Auditor the same as the Assessor?

No. The Assessor determines assessed value and handles assessment appeals. The Auditor handles ownership transfers, deductions, tax calculations, boundary information with GIS and related tax administration.

How do I print a Dearborn County property card?

Open Beacon, select Indiana and Dearborn County, search by name, address or parcel number, open the blue 18-digit parcel ID and print or save the complete parcel report.

When are Dearborn County property taxes due in 2026?

The county lists May 11, 2026 for the spring installment and November 10, 2026 for the fall installment. Confirm the current balance with the Treasurer before paying.

How do I pay Dearborn County property taxes online?

Use the county-authorized dearborn-indiana-tax.com payment service. The county lists a 2.25% card fee with a $2.95 minimum and a $0.65 e-check fee.

How do I appeal a Dearborn County property assessment?

Contact the Assessor and use Form 130 and Form 134 as instructed by the county. The published 2026 deadline was June 15, 2026, so contact the Assessor immediately if that deadline was missed.

Where can I find Dearborn County deeds and mortgages?

Use the Dearborn County Recorder and Doxpop. Online Recorder indexes generally cover records from the year 2000 forward, while older documents may require office assistance.

Are Dearborn County GIS parcel lines legal boundaries?

No. Beacon and county GIS maps help locate and compare parcels but do not replace a recorded legal description, plat, section-corner record or professional boundary survey.

When can a Dearborn County property become eligible for tax sale?

The Treasurer certifies eligible delinquent property to the Auditor on or before July 1. The county states that qualifying delinquency must exceed $25 and that full payment of taxes, assessments, penalties, interest and tax-sale costs is required to remove a certified parcel from the list.

Official information checked August 7, 2026: County jurisdiction, Beacon search instructions, Auditor duties, Assessor appeal dates, tax deadlines, payment fees, penalty rules, deduction resources, Recorder coverage and fees, GIS services, transfer charges and tax-sale rules were reviewed using Dearborn County and Indiana DLGF sources.

BOR Deadline Countdown

MAR 31

Ohio's statutory Board of Revision filing deadline is March 31 for the prior tax year. Miss it and you wait until next year — no extensions.

Set your deadline to start the countdown.

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.
