Jurisdiction correction: Boone County is not an Ohio county. This page covers Boone County, Indiana, because Indiana has the official Boone County Auditor office that matches the requested property-record task. Boone County, Kentucky uses a PVA rather than an Auditor.

Quick answer: use the Assessor’s GIS first

Open the official Boone County GIS, use the search bar at the bottom of the viewer, enter an owner name, address or parcel number, and open the matching property. When searching by parcel, remove the dashes before submitting the number.

1 Open county GIS Start from the official Assessor property-record page.
2 Enter one search value Use owner, address or parcel without dashes.
3 Verify the parcel Match owner, address, land and structures.
4 Use the right office Assessor, Auditor, Treasurer or Recorder.

Rural property Use road names, acreage, adjoining parcels and map location.
Inactive parcel Use the Indiana DLGF Sales Search for a sales disclosure tied to an inactive parcel.

2026 assessment context

Boone County states that annual trending keeps assessed values aligned with market activity. The Assessor also reports a state-set 2026 agricultural-land base rate of $2,120 per acre before local soil-productivity and other applicable adjustments.

Agricultural-rate warning: The statewide base rate is not the final assessed value of every agricultural acre. Soil productivity, land classification, influence factors and parcel use can affect the property record.

GIS and property-boundary safety

Use Boone County maps without treating them as surveys

The GIS viewer is useful for parcel research, surrounding-owner review and property-card access. Boone County specifically warns that parcel-map lines may not be exact and should not be used to settle a boundary dispute.

GIS is useful for
  • Locating the tax parcel
  • Viewing nearby parcels
  • Finding owner information
  • Opening property record cards
  • Preparing an adjoining-owner request
  • Understanding general parcel shape
A survey is needed for
  • Exact property corners
  • Fence installation
  • Tree or encroachment disputes
  • Building placement
  • Driveway or access questions
  • Legal boundary testimony

Map workflow

Search the parcel number without dashes Confirm the owner and property address.
Zoom to the parcel Review roads and adjoining properties.
Open the property record card Match the map parcel with the assessment record.
Request adjoining-owner information when needed Contact the Auditor and specify which surrounding parcels are required.
Order a survey for exact dimensions Do not use an enlarged GIS map as a legal boundary document.
Published-fee discrepancy: The Auditor’s current fee schedule lists an adjoining-owner list at $0, while an Auditor FAQ describes a $1 charge. Confirm the current charge before requesting the list.
Open Boone County GIS Review Auditor map guidance
Recorder and document research

Find deeds, mortgages, liens and plats

All recorded deeds are maintained by the Recorder. The Auditor can help identify an owner and transfer date, but the deed copy itself must be obtained through the Recorder.

Search recorded documents

Find the parcel in GIS Save the current owner, prior owner, parcel number and transfer information.
Open the Recorder’s online lookup Use the official Boone County records-search page.
Search grantor and grantee names Try both the transferring and receiving parties.
Filter by document type Look for deeds, mortgages, releases, liens, leases, plats or powers of attorney.
Match recording and property clues Compare date, legal description, parcel and party names.
Request a certified copy when required Confirm whether an online image or certified document is needed.

Contact the Recorder when an older record is missing.

Complete the sales disclosure Use the current Indiana form when the transaction requires it.
Submit the Auditor transfer fees Confirm whether the transfer is exempt or non-exempt.
Record the accepted deed Use the Recorder and follow its document and payment requirements.
Recheck deductions Boone County advises owners to review and re-file deductions when a deed or title change may affect eligibility.
Confirm the mailing address The Auditor requires the proper address-change form rather than a verbal request.
Do not change a tax-bill address by phone alone. Boone County states that a proper form must be filed in person or submitted by mail because tax-record address changes cannot be accepted as a verbal request.

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.
