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.

Kern County Property Search: Assessor, Tax Records & Maps

Kern County, California · APN, ATN, tax bills, parcel maps, deeds and assessments

Find a Kern County Parcel, Tax Bill or Recorded Map

Search Kern County property by Assessor’s Parcel Number, Assessor Tax Number or street address, then review assessment values, parcel maps, use codes, tax information and available property characteristics.

This guide explains the privacy restrictions that block online owner searches, the difference between APN and ATN records, how to pay taxes, where to find deeds, how mineral parcels differ from surface parcels and which office handles each next step.

Quick answer: start with APN, ATN or address

Use the Assessor Property Search for an APN, ATN or street address. Owner-name searches are not available, and owner names are not displayed. After finding the property, save both the APN and ATN before opening the parcel map, tax-payment system or recorded-document search.

1 Choose the identifier APN for the parcel, ATN for taxes or address for discovery.

2 Search simply Use digits or the street name without city and ZIP.

3 Verify the result Match address, APN, ATN, use code and map.

4 Use the right office Assessor, Tax Collector, Recorder, Auditor or Appeals Board.

New buyers and new construction

Understand supplemental assessments and tax bills

A purchase, ownership change or completed new construction can create a supplemental assessment effective from the first day of the month after the event. This is separate from the regular annual bill.

Read the Notice of Supplemental Assessment Compare the prior value, new value, event date and net change.

Expect a separate bill when value increased A bill over the applicable minimum is generally issued about 45 days after the assessment notice.

Do not assume the lender will pay it Mortgage servicers do not receive the supplemental bill; it is sent directly to the owner of record.

Check Homeowners’ Exemption eligibility File within 30 days of the notice for the full supplemental exemption when eligible.

Contact the Assessor when the value is wrong Provide the purchase, construction or market evidence promptly.

Appeal within 60 days if unresolved The deadline is measured from the notice mailing date.

Pay the bill despite the appeal Filing an appeal does not stop the tax due date.

Multiple-bill warning: A transaction between January 1 and May 31 can create supplemental assessments covering portions of two fiscal years. Multiple ownership or construction events can also produce multiple bills.

Read supplemental-bill guidance

Parcel combinations and divisions

Request a parcel combination or division

Kern County provides separate Assessor forms to request that eligible parcels be combined or that an assessment parcel be divided. An Assessor parcel change is not the same as obtaining subdivision approval or creating a legal building site.

Ten practical answers

Kern County property search FAQs

How do I search Kern County property records?

Use the official Kern County Assessor Property Search. You can search by an 8- or 9-digit APN, a 10- or 11-digit ATN, or a partial or complete street address.

Can I search Kern County property by owner name?

No. Kern County does not permit owner-name searches in its online Assessor property search, and owner names are not displayed in the search results.

What is the difference between an APN and an ATN?

An APN is the Assessor’s Parcel Number used to identify an assessment parcel and locate its map. An ATN is the Assessor Tax Number commonly used for tax-bill searches and payments.

How do I search a Kern County address?

Enter the street number when known and the street name only. Do not enter the street type, city or ZIP code. Add more letters or the house number when more than 100 results are returned.

When are Kern County secured property taxes due?

The first installment is due November 1 and becomes delinquent after 5 p.m. on December 10. The second installment is due February 1 and becomes delinquent after 5 p.m. on April 10.

How can I pay Kern County property taxes online?

Use the official Kern County Treasurer-Tax Collector website. Search by property address, ATN, file number or available bill information, verify the parcel and tax year, review the service fee and save the payment confirmation.

How do I appeal a Kern County property assessment?

Contact the Assessor first to request a value review. A formal regular-roll appeal must be filed with the Clerk of the Board during the applicable filing period. Kern County currently charges a non-refundable $75 filing fee for each application and requires one application per APN.

Where can I find a Kern County deed or mortgage?

Use the Recorder’s Official Records search by grantor or grantee, document number, document date or document class. Online APN searches for recorded documents have not been available since December 9, 2024.

Are Kern County GIS parcel lines legal boundaries?

No. GIS and Assessor parcel maps are produced for assessment and identification purposes. They do not prove legal-lot status, exact boundaries or that a parcel is a valid building site.

What is the Kern County Homeowners’ Exemption?

An eligible owner who occupies the home as a principal residence on January 1 may claim an exemption of up to $7,000 from assessed value. Filing deadlines apply, and new owners must return the claim form rather than assume the exemption is automatic.

Information checked August 7, 2026: Search restrictions, APN and ATN formats, address-search instructions, tax deadlines, online-payment costs, appeal filing fees, Proposition 8 dates, Recorder search limits, map disclaimers, exemptions, supplemental bills, business-property rules and office contacts were checked against official Kern County sources.

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.
