Find a Cobb County Parcel, Read the Assessment, Then Use the Right Office
Searchers often type “Cobb County Property Appraiser,” but the official Georgia office is the Cobb County Board of Tax Assessors. Use the assessor’s property search to find parcel records, ownership display, property address, fair market value, assessed value, exemptions, sales information and appeal details.
For 2026, Cobb County states that assessment notices were mailed on June 5. The notice is not a tax bill. Under Georgia law, property is assessed at 40% of fair market value, and owners generally have 45 days from the notice date to appeal.
Start here: what do you need from Cobb County property records?
The Cobb County Board of Tax Assessors is the right starting point for property values and assessment records. It is not the payment office and it is not the deed-recording office.
Use the official assessment search
Find the parcel by address, owner or parcel number. Verify the correct record before relying on values, exemptions or sales history.
Open Cobb property searchUse Cobb’s 2026 estimator
The Tax Commissioner’s estimator uses 2026 assessment data and 2025 adopted millage rates. It is an estimate only, not a legal tax bill.
Open 2026 tax estimatorUse Superior Court Clerk records
Deeds, mortgages, liens, plats and recorded real-estate documents are handled by the Clerk, not by the assessor record.

How to search Cobb County property records
The official assessor website links to property search tools for Cobb County assessment records. Use the strongest identifier you have, then confirm the property before using the record for an appeal, tax estimate, deed search or exemption question.
-
Open the official Cobb County Board of Tax Assessors website.
Start at assessor.cobbcounty.gov or go directly to the official property-search link. -
Search by parcel number when you have it.
Parcel number is the safest way to land on one record. Use it from a notice, tax bill, prior record, closing document or map result. -
Use address search when you do not know the parcel number.
Try the house number and street. If the search fails, remove extra punctuation, apartment/unit uncertainty, directional errors or spelling variations. -
Use owner search carefully.
Owner names can involve trusts, estates, LLCs, common names, spelling changes or prior owners. Always verify the physical address and parcel number. -
Open the matching property record.
Check owner display, situs address, parcel ID, property class, land/building details, sales history, fair market value and assessed value. -
Compare the assessment notice.
For 2026, the county says notices show prior and current fair market value, exemption/credit codes and estimated tax savings. The notice is not the final tax bill. -
Save the parcel number before leaving the page.
You may need it for the tax estimator, Tax Commissioner, Clerk records, Board of Equalization or assessor contact.
Parcel number: save this before you move to taxes, maps or deeds
Cobb County property work gets easier once you know the parcel number. It connects the assessment record, map view, annual notice, tax estimate, appeal paperwork and many Clerk-record searches.
| Identifier | How it helps | What to verify |
|---|---|---|
| Parcel number | Best reference for assessment records, tax estimates and appeals. | Copy it exactly from the official record or notice. |
| Property address | Good starting point for homeowners, buyers and agents. | Do not confuse physical address with mailing address. |
| Owner display | Useful for confirming a likely match. | Not proof of current residence or legal title. |
| Legal description | Supports deed and title research. | Use Clerk records for recorded documents and certified copies. |
| Tax district | Explains which county, city, school or special tax components may apply. | City taxes may not be included in every county estimator result. |
What you may find in a Cobb County assessment record
A property record is a tax-assessment record. It can be very useful, but it should not be treated as a full title report or legal boundary document.
| Record area | What to check | Common mistake |
|---|---|---|
| Property address | Physical location of the parcel when listed. | Using mailing address as proof of where the owner lives. |
| Owner display | Name shown for assessment purposes. | Treating the owner line as a deed search or title opinion. |
| Land and building details | Size, use, structures and other characteristics shown by the system. | Appealing value before checking whether the property facts are wrong. |
| Sales information | Recent transfers and sale history when available. | Assuming every transfer is an arm’s-length comparable sale. |
| Fair market value | The county’s value estimate as of January 1 for the tax year. | Calling it the tax bill or guaranteed sale price. |
| Assessed value | Georgia generally uses 40% of fair market value for taxable assessment math. | Applying a tax rate to 100% of fair market value without checking assessment basis. |
| Exemptions and credits | Homestead, special exemptions, credits or preferential assessment codes where shown. | Assuming a seller’s exemption automatically applies to a buyer. |
Cobb County maps and GIS: useful for property research, not legal boundaries
Cobb County provides GIS resources, including a GIS Hub and Tax Parcel Viewer. Use maps for parcel orientation, nearby-property context, geographic review and tax-district research. Do not use a GIS parcel line as a boundary survey, title report or zoning approval.
Practical research
- Locating a property visually.
- Checking nearby parcels.
- Reviewing general geographic context.
- Comparing parcel and address information.
- Finding county mapping resources.
Legal proof
- Boundary survey.
- Title search.
- Easement determination.
- Zoning approval.
- Engineering or construction plan.
How to use the parcel map safely
Cobb County value terms: fair market value, assessed value and estimated tax
Georgia assessment records do not work like Florida property-appraiser records. Cobb County’s notice and estimator focus on fair market value, 40% assessed value, exemptions, credits, millage and estimated taxes.
| Term | Plain-English meaning | What not to assume |
|---|---|---|
| Fair market value | The county’s estimate of property value for the tax year, based on market evidence and property data. | It is not your tax bill, sale price guarantee or private appraisal. |
| Assessed value | Georgia property is generally assessed at 40% of fair market value. | Do not multiply millage by 100% of fair market value without checking the assessment basis. |
| Estimated tax savings | The 2026 notice format includes estimated savings tied to exemptions, credits or preferential assessments. | It is an estimate using previous-year millage, not a final tax bill. |
| Tax estimator | Cobb’s 2026 estimator uses 2026 assessment data and 2025 adopted millage rates. | It is county-tax estimate only and may exclude city taxes, penalties, interest, fees and special classifications. |
| Tax digest | The total value of property in the county, used in local tax planning and rate discussions. | Do not treat countywide digest growth as your individual tax bill. |
How a Cobb County value can move toward a tax estimate
Homestead exemptions and 2026 Cobb County filing notes
Homestead is a tax benefit for homeowners who live in the home as their primary residence. Cobb County’s 2026 assessment information states that the 2026 homestead deadline was July 20, 2026. County communications also told homeowners to apply by April 1 to ensure the exemption goes into effect for the 2026 bill, so always follow the current official CobbTax instructions for the year you are filing.
Homestead is not automatic forever
Apply through the official CobbTax process when eligible, and report ineligibility when required. Do not assume a seller’s exemption transfers to the buyer.
Box 3 warning
Cobb’s 2026 notice explanation says owners no longer eligible for Homestead must report ineligibility before the appeal deadline or face taxes, interest and a 50% penalty on improperly reduced tax.
Box 11 estimate
The 2026 notice includes estimated tax savings from approved exemptions, credits or preferential assessments. It is calculated using prior-year millage and can differ from the final bill.
How to handle Homestead safely
- Open the official CobbTax homestead information or filing portal.
- Confirm the tax year and whether the application window is open.
- Verify that the property is your primary residence and that your ownership information is correct.
- Prepare identification, residency and ownership documentation requested by the official filing system.
- Submit through the official county-approved method.
- Save confirmation, receipt or filing proof.
- Later check the assessor or tax record to verify the exemption appears on the correct property.
- If you become ineligible, follow the official process to remove or report the exemption before the required deadline.
Assessment review and appeals in Cobb County
If you disagree with the fair market value on your Cobb County Notice of Assessment, you generally have 45 days from the date shown on the notice to file a written appeal. For 2026, Cobb says notices were mailed June 5, but the date on your notice is the practical deadline anchor.
Appeal workflow
- Read the assessment notice and copy the notice date, parcel number and fair market value.
- Open the official assessment record and check land, building, sales and property-characteristic details.
- Decide what you are challenging: fair market value, uniformity, taxability, property data or exemption treatment.
- Gather evidence before filing: comparable sales, photos, repair estimates, measurements, permits, appraisal support or correction documents.
- File a written appeal with the Board of Tax Assessors by the deadline.
- Keep proof of timely filing.
- If the matter continues, follow the Board of Equalization notice and hearing instructions.
- If you disagree after a Board of Equalization decision, check the official Superior Court appeal rules and deadlines.
| Issue | Stronger evidence | Weaker argument |
|---|---|---|
| Market value | Comparable sales similar in location, size, age, condition and sale timing. | One online estimate or an unrelated neighborhood sale. |
| Condition | Dated photos, inspection notes, contractor estimates or repair records. | “The house needs work.” |
| Size or property facts | Survey, floor plan, measurements, permit record or reliable document. | Unsupported square-footage guess. |
| Exemption or credit display | Application confirmation, tax records, eligibility documents and county correspondence. | Assuming a prior owner’s exemption applies to the new owner. |
Tax bills and payments go to the Cobb County Tax Commissioner
The Tax Commissioner’s Office is responsible for collecting and disbursing ad valorem property taxes. The Board of Tax Assessors sets values for assessment purposes; it does not collect the bill.
Board of Tax Assessors
- Places fair and equalized value on taxable property.
- Maintains assessment records and notices.
- Handles value review and appeal intake.
- Handles certain exemption, inventory Freeport and conservation-use applications.
Tax Commissioner
- Collects and disburses property taxes.
- Provides tax statements and payment information.
- Runs the 2026 county tax estimator.
- Handles property-tax payment questions.
- Open the official CobbTax payment or Tax Commissioner page.
- Search using parcel ID, property address or owner name where accepted.
- Verify the property, tax year, district and balance.
- Review the due date, payment method and any fee, penalty or interest language.
- Remember that city taxes may be billed separately if the property is inside a city.
- Save the confirmation or receipt after payment.
Deeds, mortgages, liens and real-estate records
The assessor record is not a title report. The Cobb County Superior Court Clerk records deeds, mortgages, liens, plats, condominium floor plans, UCC filings and other real-estate records. Use the Clerk when you need recorded legal documents or certified copies.
Cobb County Superior Court Clerk
The Clerk’s Real Estate records are the correct place for deeds, mortgages, liens and recorded property documents. The official records are kept at the Cobb County Superior Court Clerk’s Real Estate Office, 10 East Park Square, Marietta, GA 30090.
Not legal title
The assessor’s owner display can help identify a parcel, but it does not prove lien status, boundary lines, marketable title, deed validity or ownership free of claims.
- Search the assessor record and save parcel number, property address and legal description.
- Open the Clerk’s real-estate records search.
- Search by name, filing date, document type, instrument number or land description where available.
- Open the matching deed, mortgage, lien, plat or other document.
- Compare legal description, recording date and parties.
- Order certified copies only from the official Clerk process when certification is required.

Common Cobb County property-search problems
Address search does not find the property
Try the parcel number if you have it. Otherwise simplify the street name, remove uncertain unit details, check spelling, and compare likely results by physical address, parcel number and map context.
Owner search returns too many records
Owner names can involve trusts, estates, LLCs, shared surnames or older ownership. Use the parcel number and property address before relying on a result.
The 2026 assessment notice looks like a tax bill
It is not the bill. Cobb County says the notice is official correspondence about fair market value. The Tax Commissioner mails the tax bill later.
The tax estimator does not match the final bill
Cobb’s 2026 estimator uses 2026 assessment data and 2025 adopted millage rates. Final bills can differ because of current rates, city taxes, exemptions, credits, penalties, interest, special classifications or account-specific details.
The seller’s taxes look much lower than my estimate
The seller may have exemptions, credits or a taxable-value history that will not apply the same way to a buyer. Use the official estimator and your own eligibility status.
The map boundary looks wrong
Use GIS for orientation and research. For legal boundary, easement, title or encroachment questions, review recorded documents and contact a surveyor, title professional or attorney.
Official resources and verification
Use these official sources for live records, property search, assessment review, tax payments, real-estate records and state-level Georgia property-tax information. Recheck dates, fees, forms, filing windows, millage and payment rules before acting.
Last reviewed: September 1, 2026. Office roles are stable, but assessment notices, appeal windows, exemption filing periods, millage rates, payment rules, portal URLs and office procedures can change.
Cobb County GA Property Appraiser FAQs

Yes. Cobb County’s 2026 assessment information states that under Georgia law properties are assessed at 40% of fair market value, and that amount is used in property-tax calculation.

Cobb County stated that 2026 assessment notices were mailed on Friday, June 5. Property owners generally have 45 days from the date shown on the notice to submit an appeal.

9. Where do I find Cobb County deeds, mortgages or liens?
Use the Cobb County Superior Court Clerk’s real-estate records search. An assessor property record helps identify the parcel, but it is not a deed search, lien search or title opinion.

An assessment appeal is mainly about the property’s value or another appealable assessment issue. If the problem is the tax rate, budget, city taxes, penalties, interest or payment balance, contact the responsible taxing authority or Tax Commissioner instead.
