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.

Use the correct system. The Assessor parcel page is a taxation and appraisal record. The Auditor index is the place for recorded deeds, liens, releases, plats and surveys. Neither an online owner display nor a GIS outline replaces a title search or professional boundary survey.

Quick answer: start with Cowlitz Property Info

Use Cowlitz Property Info to identify the parcel, Property ID, tax-record owner, assessed value, land and improvement details, payment history and conveyance clues. Then use the Auditor search for legal documents, the Treasurer for current balances and payment, or GIS for visual map research.

How property value and property tax differ

Washington law generally requires taxable property to be appraised at 100% of true and fair market value. The final tax bill also depends on levy budgets, voter-approved measures, taxing districts, exemptions, deferrals and classified-land treatment.

Copy the parcel number Parcel-number searching is often more reliable than a rural address.

Open the Assessor Map Use the official map linked from the Assessor page.

Zoom to the exact property Confirm that the map parcel number matches Property Info.

Review nearby parcels and roads Use the map for access and neighborhood context.

Use measurements only for preliminary planning Online measurements are not survey-grade evidence.

Verify legal or construction issues separately Use deeds, plats, surveys and the responsible planning or building office.

Recorded deeds, liens, plats and surveys

Search the Auditor’s public land-record index

The Cowlitz County Auditor records real-estate documents, liens, maps, plats and surveys. Use this system when you need the legal-document trail rather than the Assessor’s tax-record owner display.

Search recorded documents in the right order

Copy clues from the property page Save the current owner, previous owner, parcel number, conveyance number and approximate transfer date.

Open the Auditor Public Record Search Accept the site terms and enter the public search.

Search all reasonable name variations Try grantor and grantee names, initials, former surnames, trusts, estates and businesses.

Limit the document type Narrow results to deeds, deeds of trust, releases, liens, plats, surveys or other relevant instruments.

Use date and recording clues Match the transfer, refinance, release or survey period.

Open the document image Verify parties, legal description, recording number and property connection.

Index-search tip: The county describes the index as similar to a library card catalogue. Search spelling variations and review the underlying document rather than relying only on the index line.

Sign up for recording notifications

Cowlitz County offers free email alerts when a document is recorded under a monitored name, parcel number or both. The alert links to the public record, but an alert does not prove that fraud occurred.

Open the county recording-notification page Read the legal disclaimer before registering.

Register name variations Include the exact forms under which property is or was held.

Board of Equalization

The general July 1, 2026 appeal deadline has passed

A later deadline may still apply. A petition is generally due by July 1 or within 30 days after the Assessor mailed the Change of Value Notice, whichever is later. Read the date on the notice before assuming appeal rights have expired.

Contact the Assessor before filing

Assessor staff can explain how the value was developed and review possible factual errors. The county may adjust the assessment when an actual error is found.

Build evidence around value—not the tax bill

Evidence that directly supports a valuation dispute
Issue	Useful evidence	Weak approach
Recent purchase	Closing statement, contract, deed and sale-condition details.	Citing only a website estimate.
Incorrect building facts	Measurements, plans, permits and dated photographs.	Saying only that the value is too high.
Poor condition	Inspection reports, repair estimates and photographs.	Listing ordinary maintenance without cost evidence.
Comparable sales	Similar arm’s-length sales near the valuation date.	Selecting only the lowest sale prices.
Land limitation	Professional reports or official evidence concerning access, septic, flood or buildability.	Using an unverified map screenshot alone.

Check the notice date Calculate the 30-day deadline from the date the value notice was mailed.

Use the correct petition Complete every required parcel, value and owner field.

State the Assessor value and requested value Explain why the evidence supports the requested amount.

Exemptions, deferrals and damaged property

Check tax-relief programs before assuming none apply

Cowlitz County property-tax relief routes
Program	Possible benefit	Important distinction
Senior and disabled-person exemption	May reduce qualifying property-tax obligations.	Age, disability, income, ownership and principal-residence rules apply.
Senior or disabled-person deferral	May postpone qualifying taxes.	Deferred tax becomes a lien and must be repaid with applicable interest.
Limited-income homeowner deferral	May defer tax for an eligible homeowner.	This is a repayment obligation, not a permanent exemption.
Destroyed property	May provide valuation relief after qualifying destruction.	Document the event date, condition and damage.
Home improvement	May temporarily exempt qualifying improvement value.	Application timing and improvement type matter.
Historic property	May provide special valuation for qualifying rehabilitation.	October 1 is listed as an important filing date.
Farm machinery and equipment	May exempt qualifying agricultural equipment.	Ownership and use requirements apply.

Exemption and deferral are not interchangeable. An exemption generally does not have to be repaid. A deferral creates a property lien and the deferred amount plus interest must eventually be repaid.

Review all tax-relief programs Email Exemptions Call Assessor: 360-577-3010

Farm, forest and open-space classification

Understand current-use valuation before buying or transferring land

Qualifying land can be taxed according to an approved current use rather than its highest and best use. Programs include Designated Forest Land, Open Space Farm and Agricultural Land, and Open Space Open Space Land.

Possible advantage

Reduced taxable value based on qualifying use
Recognition of farm, forest or open-space activity
Long-term land-use treatment

Possible obligation

Continued qualifying use
Annual or program-specific compliance
Compensating or additional tax after removal

Transferring classified land

Contact Current Use before closing Do not wait until the deed is ready to record.

Determine whether classification will continue The buyer must understand the use and compliance obligations.

Prepare the required conveyance cover sheet The county requires a tracking cover sheet for classified-land conveyances.

Complete a Notice of Continuance when applicable This requirement is in addition to the continuance entry on the REET affidavit.

Submit materials at least 15 calendar days before closing The county publishes this lead-time requirement for classified-land conveyances.

Closing-delay warning: A classified-land transfer can involve continuance, removal or compensating-tax review. Submit the package at least 15 calendar days before the expected closing date.

Business equipment and personal property

Business personal property uses a separate listing process

Tangible personal property used in business can include machinery, equipment, furniture, fixtures, supplies and tools. It is not searched or handled exactly like an ordinary residential parcel.

2026 filing status: The April 30, 2026 tangible personal-property listing deadline has passed. Contact the Personal Property Department promptly if a filing was missed or the account information is incorrect.

Identify the business account Do not use a real-estate parcel alone for equipment-listing questions.

Check possible equipment exemptions Certain farm or heavy-equipment categories may have separate applications.

Open business personal-property guidance Call Assessor: 360-577-3010

REET and deed recording

Transfer ownership through the correct county sequence

A Washington property transfer generally requires a Real Estate Excise Tax affidavit, Treasurer processing and Auditor recording. Boundary-line adjustments and mobile-home transfers can also require excise documentation.

Identify every parcel involved Verify the parcel number, Property ID and legal description.

Prepare the correct legal instrument Obtain legal assistance when uncertain which deed or document is appropriate.

Complete the REET affidavit Enter the parties, property, consideration and exemption information accurately.

Submit the excise package to the Treasurer The Treasurer acts as the Department of Revenue’s local excise-tax agent.

Ten practical answers

Cowlitz County property search FAQs

Does the Cowlitz County Auditor run the property search?

The Assessor maintains the parcel, owner-display, assessed-value and property-characteristic search. The Auditor maintains recorded legal documents such as deeds, mortgages, liens, releases, plats and surveys.

How can I search Cowlitz County property by owner or address?

Use the official Cowlitz Property Info system. Start with an owner surname, basic street address, parcel number or Property ID, then verify the result using the physical location and parcel information.

What is the difference between a parcel number and Property ID?

The parcel number identifies the mapped property record. The Property ID is a separate account-style identifier used by some county tax functions and is specifically required for automated telephone tax payments.

When are second-half 2026 Cowlitz County property taxes due?

The Cowlitz County Treasurer currently lists October 31, 2026 as the second-half property-tax deadline. Confirm weekend processing and the current balance with the Treasurer before paying near the deadline.

The county lists a $2 flat fee for e-checks and a 2.4% fee with a $2 minimum for credit and debit cards. These charges are collected by the third-party processor.

Can Cowlitz County GIS parcel lines be used as legal boundaries?

No. GIS parcel lines are useful for locating property and reviewing map context but do not replace a recorded survey, plat, deed or professional boundary survey.

How do I search Cowlitz County deeds, liens or surveys?

Use the Cowlitz County Auditor Public Record Search. Search possible grantor and grantee name variations, document type, recording information and parcel clues before opening the document image.

Can I receive alerts when a document is recorded?

Yes. Cowlitz County offers a recording-notification service that can monitor a name, parcel number or both and email a link when a matching document is recorded.

How do I appeal a Cowlitz County property value?

Contact the Assessor first and review the property facts. A Board of Equalization petition is generally due by July 1 or within 30 days after the Change of Value Notice was mailed, whichever is later.

Where are the Cowlitz County property offices located?

The Assessor, Auditor and Treasurer are located in the Cowlitz County Administration Building at 207 North 4th Avenue in Kelso, Washington. Room numbers and mailing details differ by office.

Information checked August 6, 2026: Office roles, parcel-search links, contact information, 2026 tax dates, payment fees, delinquency rules, payment identifiers, appeal timing, exemptions, classified-land transfer requirements, personal-property filing, REET rules, recording requirements and notification services were checked against official Cowlitz County 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.
