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.

Correct office for each Linn County property task
What you need	Correct office	What it handles	Important limit
Assessed value or building facts	County or City Assessor	Market value, land, buildings, classifications, credits and exemptions.	The Assessor does not collect taxes.
Ownership record or tax calculation	County Auditor	Ownership transfers affecting taxation, rollbacks, levy rates and calculated taxes.	The Auditor does not establish market value.
Current tax bill or payment	County Treasurer	Billing, payments, penalties, tax sales, redemptions and tax credits based on age or income.	The Treasurer does not change assessed value.
Deed, mortgage or lien	County Recorder	Recorded real-estate documents, copies, certifications and property-fraud alerts.	A public search is not a professional title opinion.

Common Linn County property fields explained
Field	What it means	Practical next step
Parcel ID	The identifying number assigned to the property.	Use it across Assessor, Auditor, Treasurer, Recorder and GIS systems.
Owner	The ownership name currently carried in the property record.	Use the recorded deed when legal ownership proof is required.
Assessed value	The Assessor’s estimate of property value as of January 1.	Review factual data and comparable sales before protesting.
Taxable value	Value after applicable rollback, exemption or adjustment rules.	Do not assume it will equal the full assessed value.
Land value	The value assigned to the land.	Check acreage, class, location and agricultural use.
Dwelling or improvement value	Value assigned to houses and other structures.	Verify square footage, age, condition, grade and outbuildings.
Property class	Residential, agricultural, commercial, industrial or another category.	Contact the Assessor when the actual use is materially different.
Homestead status	Whether an applicable Homestead exemption is recorded.	Check the jurisdiction-specific verification or application process.

Tax district	The levy authorities applying to the property.	Contact the Auditor for rate and rollback questions.

Value-versus-tax warning: A property’s assessment can remain unchanged while the tax bill changes because budgets, rates, rollbacks, exemptions or special assessments changed.

Auditor property role

What the Linn County Auditor does with real estate

The Auditor does not appraise buildings or land. The office receives assessed values, applies state rollbacks and local levy rates, calculates property taxes and tracks ownership transfers that affect taxation.

Ownership records

Tracks deeds, contracts, right-of-way easements and other transfers affecting taxation.

Tax calculation

Applies certified valuations, rollbacks and levy rates before sending taxes to the Treasurer.

Ag Land Credit

The Auditor determines the applicable agricultural land credit for qualifying tracts.

When to contact the Auditor

Ownership is not updated after a recorded deed

Tax district or levy-rate question

Rollback or calculated-tax question

Building-on-leased-land transfer

Historical tax or ownership routing

Parcel-map or digital-data routing

Auditor call script “I am calling about parcel [parcel ID] at [address]. The Assessor record shows [owner/value], and the deed or tax record shows [different detail]. Can you confirm the current taxation ownership, tax district and whether the transfer has been processed?”

How values are established

Understand Linn County assessments before protesting

The assessment date is January 1. Iowa requires real property to be reassessed in odd-numbered years. The Assessor seeks value rather than revenue and does not determine tax rates or collect taxes.

Sales approach

Compares recent sales of properties with similar location, use, size, age and condition.

Cost approach

Considers land, replacement cost, depreciation, age and condition.

Income approach

May be used for apartments, offices and other income-producing property.

Facts to check first

Lot size and acreage

Property class and use

Year built

Living area and building size

Basement and finished space

Grade and condition

Garage, barn and improvements

Demolition or major damage

Agricultural-value note: Iowa agricultural property, excluding agricultural dwellings, is generally assessed according to productivity and net earning capacity rather than ordinary comparable residential-sale pricing.

Ten practical answers

Linn County property search FAQs

Where can I search Linn County, Iowa property records?

Use the official Linn County Assessor Real Estate Search for property outside Cedar Rapids city limits. Property inside Cedar Rapids must be searched through the Cedar Rapids City Assessor.

Does the Linn County Auditor assess property values?

No. The Assessor determines property values. The Auditor maintains ownership records, applies rollbacks and tax rates, and calculates the property taxes that are sent to the Treasurer for collection.

Can I search Linn County property by owner name?

Yes. The Assessor search supports property research, but starting with the address or parcel number often produces a more precise result. Search the previous owner when a recent transfer has not yet appeared.

Why is a Cedar Rapids property missing from the Linn County Assessor search?

The Linn County Assessor does not assess property located inside Cedar Rapids city limits. Those parcels are maintained by the Cedar Rapids City Assessor.

Are Linn County GIS parcel lines legal boundaries?

No. GIS parcel lines help identify and compare property but do not replace a recorded deed, subdivision plat, monument record or professional boundary survey.

When are Linn County property taxes due?

Property-tax installments are due September 1 and March 1. Payments can generally be made without a late fee through September 30 and March 31, with penalties beginning October 1 and April 1.

How can I pay Linn County property taxes online?

Use Iowa Tax and Tags, select Linn County and search the correct parcel. Verify the tax year, address and amount before entering payment information, then save the confirmation number.

How do I appeal a Linn County property assessment?

For property outside Cedar Rapids, request an informal review from April 2 through April 25 or file a formal Board of Review petition from April 2 through April 30. Cedar Rapids properties must use the Cedar Rapids City Assessor appeal process.

Where can I find a Linn County deed or mortgage?

Use the Linn County Recorder Real Estate Record Search. Search the grantor and grantee names, document type and recording date, then request a certified copy when required.

How do I apply for Linn County Homestead or 65 Plus exemption?

Find the parcel through the correct Assessor, open the Homestead application link within the parcel record and submit the required form. Cedar Rapids residents must apply through the Cedar Rapids City Assessor.

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.
