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.

Dorchester County SC Property Search, Auditor & Tax Records

Dorchester County, South Carolina · TMS search, taxes, values, maps, deeds and exemptions

Find the Parcel, Then Use the Correct Tax Office

Dorchester County property research works differently from an Ohio county-auditor system. Real-estate values and the public property search are handled by the Assessor, the Auditor calculates taxes and administers several exemptions and personal-property functions, the Treasurer accepts current payments, and the Register of Deeds maintains land documents.

Use this guide to search by TMS number, owner, address, account number or mobile-home information, understand the result, check tax status, use GIS, apply for the 4% Legal Residence or Homestead benefit, appeal an assessment, locate a deed and resolve delinquent taxes.

Jurisdiction correction: Dorchester County is in South Carolina, not Ohio. More importantly, the real-estate property search belongs to the Assessor, not the Auditor. Using the wrong office can send you in circles.

Quick answer: where should you start?

For a house, land parcel or mobile home, start with the official Dorchester County CAMA Parcel Lookup. Search using the TMS number, account number, owner name, street information or mobile-home identifier. After opening the correct record, save the TMS number because it is the most useful identifier for GIS, tax and delinquent-property research.

1 Assessor Search property and check appraisal value.

2 Auditor Tax calculations, Homestead and personal property.

3 Treasurer Current tax payments and receipts.

4 Register of Deeds Deeds, mortgages, plats and liens.

Best single identifier: save the property’s TMS number. It connects the property search, GIS map, tax record and delinquent-property tools.

Office-routing guide

Assessor vs Auditor vs Treasurer vs Register of Deeds

Dorchester County divides property responsibilities among several offices. The word “Auditor” on a tax bill does not mean the Auditor determines the market value of your home.

Use the office that can actually solve the problem
Your question	Correct office	What it handles
What is my real-estate value?	Assessor	Appraisal of real estate and manufactured homes.
Where is the online property search?	Assessor / GIS	CAMA records, TMS numbers, property cards and GIS.
Why is my real property classified at 4% or 6%?	Assessor	4% Legal Residence and real-property assessment ratio.
How was my tax calculated?	Auditor	Tax calculation after value, ratio and millage information are established.
Do I qualify for Homestead?	Auditor	South Carolina Homestead Exemption applications.
Where do I pay a current tax bill?	Treasurer	Current taxes, payments, receipts and county collections.
My tax is already delinquent.	Delinquent Tax	Past-due property taxes, penalties, collection and tax-sale process.
I need the deed or mortgage.	Register of Deeds	Recorded deeds, mortgages, liens, plats and other land records.
My vehicle or boat value seems wrong.	Auditor	Personal-property assessment functions and applicable appeals.

The Auditor does not: accept current tax payments, appraise real estate, approve the 4% Legal Residence classification, set tax rates, administer waste-disposal fees or collect delinquent taxes.

CAMA search micro-guide

Search Dorchester County property records by TMS, owner or address

The official CAMA lookup provides more search options than a generic owner-name database. Use the field that contains your most reliable information.

Official CAMA search fields
Search field	What to enter	Best use
Tax Year	Four-digit year	Leave blank when you want the current tax year.
TMS #	TMS number without dashes or decimal	Best for exact parcel identification.
Account #	County account identifier	Helpful when copied from an existing county record.
Owner Name	Last name, or last and first	Use surname alone for a broader list.
Street Number	Property’s street number	Combine with a simplified street name.
Street Name	Main street name	Avoid extra address wording when troubleshooting.
Street Type	Choose from dropdown	Select only when needed to narrow results.
MH Decal #	Mobile-home decal number	Useful for manufactured/mobile-home records.
MH Serial #	Mobile-home serial number	Useful when the street address or owner search fails.

TMS search

Copy the TMS from a tax bill or previous record.
Remove dashes and decimal punctuation.
Enter only the TMS initially.
Select the correct result.
Verify the property location.

Owner search

Enter the last name first.
Run the search.
Add the first name if too many results appear.
Try a trust, estate or entity name where applicable.
Check a former owner after a recent sale.

Address search

Enter the street number.
Add the main street name.
Select the street type only if needed.
Remove extra address details if no result appears.
Use GIS when the address is uncertain.

After you find the parcel

Open the matching row Compare owner name, subdivision and street address before relying on the parcel.

Save the TMS number Use it in GIS, tax and delinquent-property searches.

Save the account number It provides a second identifier if you need county staff assistance.

Review the property card Check land, buildings, value, classification and available ownership data.

Decide the next task Value question goes to Assessor; payment goes to Treasurer; deed goes to Register of Deeds.

Update timing: Dorchester County states that property changes made during the current day generally display in the online parcel information within 24 hours. If a recent change is missing, check again the next day before assuming it was not processed.

Important property information and the next action
Record item	What it tells you	What it does not prove
TMS number	County tax-map identifier for the parcel.	Does not replace a legal description.
Account number	Administrative property-account identifier.	Do not substitute it for the TMS when a tool specifically requests TMS.
Owner name	Ownership information reflected in the county property system.	Use the recorded deed when legal title proof matters.
Market value	Assessor’s appraisal of real property.	It is not the tax amount.
Assessment ratio	Percentage applied under South Carolina property classification rules.	Do not assume every residential parcel qualifies for 4%.
Property characteristics	Available land and improvement information.	Verify errors before an appeal.
GIS boundary	Visual representation of parcel boundaries based on recorded information.	Not an engineering or land-conveyance survey.

County disclaimer: the online Assessor/GIS information is described by Dorchester County as notional and not intended for engineering or land conveyance. Use deeds, plats and a professional survey for legal-boundary work.

Reassessment and appeals

Why the value changes—and how to appeal it

Dorchester County states that the Assessor conducts a countywide reassessment every five years, appraises new construction and processes appeals involving values generated by the Assessor’s Office.

Do not confuse an Assessment Notice with a tax bill

An Assessment Notice tells you about a change in property value or classification. It does not tell you the final amount of property tax you will owe.

You have 90 days from the mailing of the notice

If you disagree with the new Assessor value, Dorchester County says the appeal must be filed in writing with the Assessor within 90 days of the mailing of the Assessment Notice.

Do not wait for the tax bill. By the time the bill arrives, the 90-day valuation-appeal window may already have expired.

Build evidence before filing

Read official reassessment & appeal guidance

Major homeowner savings

Apply for the 4% Legal Residence assessment correctly

South Carolina’s 4% Legal Residence classification is one of the most important property-tax issues for owner-occupied homes. Dorchester County states that an approved primary legal residence receives the 4% assessment ratio and an exemption from property taxes levied for school operations.

This is handled by the Assessor—not the Auditor.

Micro steps before applying

Wait until the deed has been recorded Dorchester County warns that applying before the Register of Deeds records the deed can cause the application to be denied or returned.

Check your identification address The property address should match the address on your driver’s license and vehicle registration unless the Assessor approves other identification circumstances.

Open the official application Choose the online application or current paper form.

Read the required-document list Requirements depend on the applicant’s situation.

Complete every applicable field Do not leave ownership or residency sections incomplete.

Submit to the Assessor The county recommends the St. George office for returning the paper form and specifically says not to fax the Legal Residence application.

4% versus 6% matters

4% Legal Residence

Generally for an approved primary owner-occupied residence.

6% Residential Property

Commonly applies to second homes, rentals and other residential property that does not qualify as the owner’s legal residence.

Audit risk: Dorchester County audits Legal Residence claims. Vacation homes, multiple homes and rental properties do not qualify merely because the owner owns the property.

If a taxpayer received the 4% ratio but later becomes ineligible and does not notify the Assessor within the required period, the county describes substantial tax, penalty and interest consequences.

Open 4% Legal Residence application

Do not confuse with 4% Legal Residence

Homestead Exemption is a separate Auditor benefit

The Dorchester County Auditor administers South Carolina’s Homestead Exemption. It can exempt up to the first $50,000 of fair market value of a qualifying taxpayer’s home.

Basic eligibility

All of the county’s basic ownership/residency conditions must be met, and by December 31 before the exemption tax year the applicant must generally be one of the following:

Age 65+

At least 65 years old as of the applicable December 31 date.

Totally & permanently disabled

Disability must be established through an authorized state or federal agency.

Legally blind

Certification from a licensed ophthalmologist can be required.

Other county requirements

Primary legal residence

Qualifying ownership or life estate

Certain trust beneficiaries can qualify

One preceding calendar year as a South Carolina legal resident

Proof of age, disability or blindness

Surviving-spouse rules may apply

No routine annual reapplication: Dorchester County says approved Homestead recipients generally do not need to reapply every year unless circumstances such as death of the eligible owner or a move require a new application.

Apply online or in person

Confirm the qualifying residence Use the home that is actually your primary legal residence.

Prepare eligibility proof Bring the documents relevant to age, disability, blindness, trust ownership or surviving-spouse status.

Choose online or office filing The county offers an online form and in-person filing.

Use an Auditor office Applications can be handled at St. George or Summerville.

Current tax payment

Search and pay a current Dorchester County tax bill

Current property taxes are collected by the Treasurer. The county’s tax-payment link redirects to its BillTrax payment system.

Micro steps for online payment

Find the property record first Copy the TMS number and verify the owner and address.

Open the county’s official Property Taxes page Use the county page rather than searching for a payment processor independently.

Continue to BillTrax Dorchester County’s official page redirects users to the county tax-payment site.

Search the tax account Match the property and tax year before selecting a bill.

Review current status Look for balance, previous payments and whether the account has moved to delinquent collection.

Review payment fees Check the live processor screen before choosing card or electronic payment.

Save the receipt Keep the TMS, tax year, amount, date and confirmation number.

Pay in person or use a drop box

The Treasurer’s tax page states that county taxes may also be paid at the Summerville office at 500 N. Main Street or the St. George office at 201 Johnston Street. Drop boxes are available at both locations.

Drop-box timing: the county says payments placed in a drop box before 8:30 a.m. are credited to the previous day.

Current 2026 collection status

If the bill is delinquent, stop using the regular Treasurer workflow

Once a bill moves into delinquent status, collection belongs to the Delinquent Tax Office rather than the ordinary Treasurer payment workflow.

As of August 7, 2026: Dorchester County’s current delinquent-tax page states that unpaid taxes become delinquent after March 16 and a 15% past-due penalty applies when the account reaches the Delinquent Tax Office.

Viewing roads and geographic context
Researching available GIS layers
Confirming approximate parcel location

GIS should not be used for

Setting a fence line
Determining exact corners
Resolving an encroachment
Writing a deed description

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.
