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.

Quick answer: Aiken County is in South Carolina

If you searched for Aiken County Auditor, OH, the state is incorrect. There is no Aiken County property office in Ohio. The correct county is Aiken County, South Carolina.

For ordinary real-estate research, begin with the official Aiken County real-property/qPublic system rather than the Auditor office. Use the Assessor for value and classification, Treasurer for current tax payments, Auditor for tax-bill and personal-property questions, and Register of Deeds for deeds, mortgages and liens.

1 Find the parcel Search owner, address, parcel number or legal information.

2 Verify the property Match parcel number and physical location.

3 Identify your problem Value, tax, deed, map, exemption or delinquency.

4 Use the right office Assessor, Auditor, Treasurer or ROD.

Which Aiken County office handles your question?
Your task	Correct office	What it handles	Phone
Search real property or question market value	Assessor	Real-property appraisal, classification, assessment, property information, legal-residence special assessment and agricultural special assessment.	803-642-1583

Residence and exemption help

Do not confuse Legal Residence with Homestead Exemption

South Carolina property owners may encounter two different concepts: the Legal Residence special assessment handled through the Assessor and the Homestead Exemption administered by the Auditor. They are not the same program.

Aiken County residence-related property programs
Program	Office	Main purpose	Practical action
Legal Residence special assessment	Assessor	Special assessment treatment for qualifying owner-occupied legal residences.	File the county Legal Residence application and required documentation.
Homestead Exemption	Auditor	Exempts the first $50,000 of appraised value for qualifying applicants under the county’s published rules.	Apply through the Aiken County Auditor.
Agricultural special assessment	Assessor	Special property assessment for qualifying agricultural real property.	Use the Assessor’s agricultural special-assessment application.

Published Homestead eligibility clues

Aiken County says an applicant may qualify for Homestead when the property is the primary residence, the applicant satisfies the required South Carolina residency period, and as of December 31 preceding the tax year meets one of the county’s listed age, total-and-permanent disability or legal-blindness conditions.

Do not assume approval from age alone. Ownership, primary residence, residency timing and qualifying status must all be checked under the Auditor’s current application rules.

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.
