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.

Assessment Appeals Board

Appeal an assessed value during the correct period

Current 2026 status: The regular assessment-appeal filing period is open from July 2 through November 30, 2026.

Los Angeles County assessment-appeal deadlines
Assessment type	Filing period	What to check
Regular assessment	July 2 through November 30	Current roll value and market evidence as of the lien date.
Supplemental assessment	Within 60 days of the notice or bill mailing/postmark date	Change-of-ownership or new-construction value and event date.
Adjusted or escape assessment	Generally within 60 days of the notice or bill	Mailing date, adjusted value and reason for change.
Misfortune and calamity reassessment	Within six months after the proposed reassessment notice	Damage facts, value loss and notice date.

Prepare the appeal

Discuss the value with the Assessor Ask for the property characteristics, base year and assessment explanation.

Protect the formal deadline An informal review does not automatically extend the appeal period.

Use the correct assessment type Select regular, supplemental, escape, adjusted or calamity as applicable.

State the value requested Explain why the enrolled value exceeds the property’s fair market value.

Attach evidence Use comparable sales, appraisal, purchase documents, photographs, measurements or damage evidence.

Pay the filing fee or submit a waiver The published non-refundable filing fee is $46.

Continue paying taxes An appeal does not suspend the tax-payment requirement.

Appeal inquiry script “I am reviewing AIN [number] for [regular, supplemental or adjusted] assessment. The notice was mailed on [date]. Can you confirm my filing deadline, the $46 fee or waiver process, the correct application and how to submit evidence?”

Taxable-value relief

Check Homeowners’ Exemption, Proposition 8 and disaster relief

Homeowners’ Exemption

Main benefit

Reduces taxable assessed value by up to $7,000 for a qualifying owner-occupied principal residence.

Filing timing

A first-time claim is normally filed with the Assessor. February 15 is the standard deadline for the full exemption for that year.

Owner occupied the home as principal residence

Eligibility existed on the January 1 lien date

Current BOE-266 claim form

AIN and property address

Ownership and occupancy information

Notification when the property is no longer eligible

Proposition 8 decline-in-value review

Proposition 8 can temporarily reduce assessed value when the property’s January 1 market value falls below its factored base-year value. The reduced assessment is reviewed annually and can later rise by more than 2% as market value recovers, but it cannot exceed the factored base-year value without a new reassessable event.

Protect the appeal deadline: A request for an Assessor decline-in-value review does not automatically preserve formal appeal rights. File an appeal before the deadline when the Assessor has not completed the review.

Misfortune and calamity relief

Property damaged or destroyed by fire or another qualifying calamity may be eligible for temporary reassessment. Prepare the damage date, photographs, reports, repair estimates and evidence of the property’s condition before and after the event.

Review Homeowners’ Exemption Request decline-in-value review Read California Proposition 8 guidance

After purchase or construction

Understand supplemental assessments and bills

A change in ownership or completed new construction can establish a new assessed value and generate one or two supplemental tax bills in addition to the regular annual bill.

A reassessable event occurs Property changes ownership or qualifying new construction is completed.

The Assessor establishes the new value The value is based on the date of the ownership change or construction completion.

The prior assessed value is subtracted The difference becomes the net supplemental assessment.

The Auditor-Controller calculates the tax The calculation is prorated for the remaining portion of the fiscal year.

The Tax Collector issues the bill Depending on the event date, one or two supplemental bills may be generated.

The annual bill remains payable A supplemental reduction or appeal does not automatically cancel the annual secured bill.

Buyer planning tip: Do not assume the seller’s existing tax amount will remain your full tax obligation. Budget for supplemental bills after a purchase.

Ten practical answers

Los Angeles County property-search FAQs

Is Los Angeles County in Ohio?

No. Los Angeles County is in California. Property searches are handled primarily by the Los Angeles County Assessor, while the Auditor-Controller, Treasurer and Tax Collector, Registrar-Recorder/County Clerk and Assessment Appeals Board handle different parts of the property-tax and public-record process.

How do I search Los Angeles County property records?

Use the official Los Angeles County Assessor Portal. Search by the 10-digit Assessor’s Identification Number or by street address, then verify the parcel using its situs address and AIN.

Can I search Los Angeles County property by owner name?

The primary Assessor Portal is designed around AIN and address searches rather than a broad owner-name search. Use the address or AIN when available. Recorded real-estate indexes are not provided as a free online public index by the Registrar-Recorder.

What is an AIN in Los Angeles County?

The Assessor’s Identification Number is the 10-digit number assigned to a real-property tax parcel. It is also described as the map book, page and parcel number and is used for property searches and secured-tax payments.

Where can I find a Los Angeles County deed or lien?

Use the Los Angeles County Registrar-Recorder/County Clerk. Real-estate records can be viewed by appointment at the Norwalk headquarters or copies can be requested through the official online, mail or in-person process.

When are Los Angeles County secured property taxes due?

The first installment is due November 1 and becomes delinquent after December 10. The second installment is due February 1 and becomes delinquent after April 10. Weekend and holiday extension rules may apply.

What are the Los Angeles County online payment fees?

Electronic-check payments are offered without a County payment fee. Credit and debit card payments currently carry a third-party service fee of 2.22%, with a stated minimum fee of $1.49.

How do I appeal a Los Angeles County property assessment?

Discuss the value with the Assessor and file an Assessment Appeal Application when formal review is needed. The regular filing period is July 2 through November 30. Supplemental, escape and adjusted assessments generally have separate 60-day filing periods.

What is the Los Angeles County Homeowners’ Exemption?

A qualifying owner-occupied principal residence may receive a $7,000 reduction in taxable value. A first-time claimant generally files once with the Assessor, and February 15 is the normal deadline for the full exemption for that year.

Are Los Angeles County parcel-map lines legal boundaries?

No. Online parcel and map information is intended for assessment and research purposes. It does not replace the recorded deed, subdivision map, survey or professional boundary determination.

Information checked August 7, 2026: Assessor Portal functions, office responsibilities, secured-tax dates, payment fees, direct-assessment guidance, Recorder access restrictions, record-copy options, appeal periods, appeal fees, Homeowners’ Exemption and Proposition 8 rules were checked against current Los Angeles County and California government sources.

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.
