Find the Right Cobb County Property Record
Use the Cobb County Tax Assessor’s property-search system for owner, address and parcel lookups, then review fair market value, assessed value, exemptions, sales, improvements and property characteristics before moving to taxes, deeds or appeals.
This guide explains the exact search routes, Georgia’s 40% assessment rule, Cobb’s changed 2026 assessment notice, July appeal timing, homestead and floating-exemption issues, tax bills, GIS maps, recorded deeds, personal property and fixes for missing or incorrect records.
Fast Answer: Assessor, Tax Commissioner or Clerk?
Cobb Board of Tax Assessors: search parcels, determine fair market value, apply assessment rules, maintain property characteristics, process returns/exemptions and handle the first stage of valuation appeals. Cobb Tax Commissioner: homestead administration, tax bills, tax payments and collections. Superior Court Clerk: deeds, plats, liens and recorded real-estate documents.
Choose the Correct Cobb County Property Office
Searching “Cobb County tax assessor” can lead to three different property workflows. Pick the record you actually need first.
Tax Assessor
Use for property search, fair market value, assessed value, sales, building/land facts, real-property returns, business personal property and valuation appeals.

Official Cobb County GIS Open GIS ResourcesHow to Search Cobb County Property Records
Use a single clean identifier first, verify the parcel, then move to values, tax bills, deeds or appeals.
Open the official Cobb property search
Use the Tax Assessor’s linked property-search system for a real-property lookup rather than a third-party people or real-estate site.
Search by owner, location address or parcel number
Use whichever identifier you know best. An exact parcel number is strongest; an address is usually easiest for homeowners.
Simplify an address that returns nothing
Cobb’s separate address helper wants only the house number and street. Do not enter an apartment/unit, city, state or ZIP on the first search.
Verify the correct property
Match situs address, owner, parcel number, legal description, land area and property class before relying on the record.
Review values, sales and improvements
Check the selected tax year, fair market value, assessed value, exemptions, sales history and building/land facts.
Save the parcel ID
Use the parcel number when moving to tax estimates, deed research, GIS, support calls, returns or appeal paperwork.

How to Read a Cobb County Tax Assessor Record
Field |
What it means |
Common mistake |
|---|---|---|
Owner |
Ownership currently carried in Assessor records. |
Treating it as a complete title opinion. |
Parcel ID |
Primary identifier for appraisal, tax, GIS and document research. |
Relying only on an owner name when several parcels match. |
Fair Market Value |
Assessor’s estimate of market value for the applicable year. |
Thinking this is already the taxable assessed value. |
Assessed Value |
Georgia generally assesses property at 40% of fair market value. |
Multiplying the full market value directly by the millage rate. |
Exemptions |
Homestead or other eligible reductions reflected in the tax workflow. |
Assuming an exemption applies to every taxing component in the same way. |
Sales |
Recorded transaction history used for research and appraisal context. |
Treating every transfer as an arm’s-length comparable sale. |
Improvements |
Assessor building/structure characteristics. |
Ignoring obvious factual errors in square footage, class or improvements. |
Legal Description |
Parcel-identification wording used in appraisal records. |
Using an appraisal description instead of the recorded deed/plat for a legal transaction. |
2026 Cobb County Annual Notice of Assessment: What Changed?
Cobb mailed 2026 Commercial, Residential and Personal Property Annual Notices on June 5. Senate Bill 566 changed the state-required notice format beginning January 1, 2026.
Box 3: Homestead eligibility warning
If the property is no longer eligible for the homestead benefit shown on the notice, Cobb directs the owner to report the ineligibility through the Tax Commissioner before the applicable appeal deadline.
Failure to report an improperly retained benefit can lead to unpaid taxes, interest and a penalty equal to 50% of the improperly reduced tax amount.
Box 7: Value comparison
Use this area to compare previous and current fair market value and any applicable preferential assessment information.
Box 10: Exemptions and credits
Review the exemptions, credits or preferential programs shown for the parcel. Do not assume a missing benefit will fix itself before the bill is issued.
Box 11: Estimated savings
The new notice shows an estimated tax-savings figure using current exemptions/credits and prior-year millage. It is not the final 2026 tax bill.
Cobb County 2026 Property Tax Timeline
Real and personal property is valued for the tax year based on the applicable January 1 status.
Real Property Taxpayer Returns and most personal-property returns use the January 1 through April 1 filing period.
Cobb mailed Residential, Commercial and Personal Property Annual Notices of Assessment.
The 45-day statutory period from Cobb’s June 5 mailing ended July 20.
Cobb’s current 2026 notice guidance identifies July 20 for the homestead action described for this cycle. Do not reuse this date automatically in a later year.
Cobb’s current guidance says the Tax Commissioner expects to mail property-tax bills around August 15.
The current Cobb guidance expects payment around October 15. Follow the exact due date printed on the actual bill.
How to Appeal a Cobb County Property Assessment
An appeal challenges value, uniformity, taxability, an exemption decision or another appealable assessment issue. It is not the same as filing a Taxpayer Return.
What a timely Cobb appeal should identify
- Property street address.
- Parcel ID.
- Owner/contact information.
- Grounds for appeal.
- Your asserted property value when required.
- Supporting evidence or explanation.
- Email and daytime phone number for easier Assessor contact.
Georgia PT-311A: Choose the Correct Appeal Route
The current state form requires the property and appeal grounds, the owner’s value assertion, and one appeal method.
Appeal route |
Use it when |
Important limitation |
|---|---|---|
Board of Equalization |
Standard local formal review after the Board of Tax Assessors process. |
Follow BOE deadlines after the Assessor/BTA decision. |
Arbitration |
Qualifying valuation disputes. |
Limited to valuation issues and can involve additional procedural costs. |
Hearing Officer |
Qualifying non-homestead/contiguous real property or wireless personal property over the state threshold. |
Limited grounds include value and uniformity. |
Superior Court |
Direct court route only where statutory requirements and Board consent are satisfied. |
Court filing requirements and fees can apply. |
Common appeal grounds on PT-311A
- Value.
- Uniformity.
- Taxability.
- Exemption denied.
- Breach of covenant.
- Denial of covenant.
What Happens After You File a Cobb Property Appeal?
Assessor acknowledges the appeal
The office logs the filing and sends acknowledgment before appraisal review.
Appraisal staff review the record and evidence
Staff compare property characteristics, sales, condition and the taxpayer’s evidence.
Board of Tax Assessors acts on the appeal
The Board may change the assessment or leave it unchanged and issues the next decision/notice.
Unsatisfied taxpayer can continue to BOE
If the Board of Tax Assessors changes the value and you remain dissatisfied, Cobb explains that you generally have 30 days to continue the appeal to the Board of Equalization. If no adjustment is made, the appeal is forwarded to the BOE.
BOE considers the dispute
The citizen Board of Equalization hears the qualifying assessment dispute. There is no BOE filing charge unless you choose to incur representative or professional costs.
Superior Court can follow a BOE decision
Cobb states that an appeal from the BOE decision generally must be filed within 30 days through the Board of Tax Assessors.
Taxpayer Return vs Appeal: Do Not Use the Wrong Form
Real Property Taxpayer Return
Use the return during the normal January 1–April 1 period when declaring the value you believe the property had on January 1 or reporting qualifying property changes.
Cobb says real-property returns must be delivered in person or by mail; they are not accepted by fax or email.
Assessment Appeal
Use an appeal after receiving an Annual Notice when disputing the assessment, uniformity, taxability, exemption denial or another appealable decision.
A Taxpayer Return is not an appeal.
Cobb County Homestead Exemption: 2026 Filing Issue
Homestead exemptions are administered through the Cobb Tax Commissioner, while the Assessor values the property. Do not confuse the two offices.
Basic Georgia homestead checkpoints
- Own the qualifying property.
- Use it as your legal residence.
- Meet the applicable January 1 ownership/residency requirements.
- Do not claim an incompatible homestead benefit elsewhere.
- Report loss of eligibility when required.
- Confirm that approved benefits appear on the current property/tax record.
How Cobb’s Floating Homestead Exemption Works
Cobb’s existing floating homestead system is important because it can separate market-value growth from part of the County General Fund tax calculation.
What it does
Cobb explains that the floating exemption can increase when a qualifying homestead property is reassessed, helping prevent the County General Fund M&O portion from increasing solely because of reassessment.
What it does not freeze
It does not automatically freeze every tax component. Cobb specifically distinguishes school, bond, fire and other taxing components from the County General Fund M&O benefit.
Cobb County Property Tax Search, Bill and Payment
The Assessor determines the property value; the Tax Commissioner collects the tax. The 2026 Annual Notice is not the final bill.
Step 1: Confirm assessment
Review fair market value, assessed value, exemptions and parcel details on the Assessor record.
Step 2: Check current estimate
Cobb’s 2026 estimator can search by parcel ID, property address or owner and shows county-tax estimates using currently loaded assessment and rate information.
Step 3: Pay the actual bill
Use the Tax Commissioner’s official bill/payment system once the 2026 tax bill is issued.

Cobb County Property Tax Estimate Helper
This static helper does not perform a live county search. Copy the values from the official Cobb record to understand Georgia’s 40% assessment calculation and how millage affects an estimated tax.
Basic formula: Fair Market Value × 40% = Gross Assessed Value. Subtract applicable assessed-value exemptions, then multiply Net Assessed Value × Millage ÷ 1,000.
The actual bill can differ because exemptions do not necessarily affect every taxing component identically, multiple millage rates may apply, municipal taxes can be separate, and the tax digest can change before billing.
Cobb County Parcel Map, Zoning, Deeds and Plats
GIS and parcel research
Use Cobb GIS after finding the parcel to review map context, jurisdiction, zoning tools and nearby geography.
For zoning, first confirm whether the parcel lies in unincorporated Cobb or inside a city because incorporated municipalities control their own zoning.
Official Cobb GIS Review Zoning MapsRecorded deeds and plats
The Superior Court Clerk’s LandmarkWeb system supports searches by name, document, book/page, parcel ID, record-date range, instrument number and legal information.

Business personal property is a separate assessment workflow from residential real estate.
What may need reporting
- Furniture and fixtures.
- Machinery and equipment.
- Inventory and supplies.
- Leased or rented business assets.
- Aircraft or marine property where applicable.
2026 filing basics
- PT-50P is the primary business personal-property return.
- Return period is normally January 1–April 1.
- Assets are reported as of January 1.
- Cobb says all businesses should report even when value appears below the exemption.
- Georgia’s personal-property exemption is $20,000.
Business personal-property e-file
Cobb’s e-file system is normally available January 1–April 1 and uses the PIN sent with the business return. The Assessor says the PIN cannot be provided by phone or email. When the PIN is unavailable, use the paper-return route rather than waiting beyond the filing deadline.

Cobb County Property Search Not Working? Try These Fixes
Problem |
Likely reason |
Best next step |
|---|---|---|
Address returns nothing |
Too much mailing-address detail. |
Search only house number + street; remove unit, city, state and ZIP. |
Owner search fails |
Trust/LLC format, spelling or recent deed. |
Use a shorter owner phrase or search by address/parcel. |
New owner not shown |
Recorded deed and Assessor update are on different timelines. |
Verify the deed in LandmarkWeb, then contact the Assessor. |
Value jumped |
Annual revaluation, recent sales, condition/data or market changes. |
Compare prior/current FMV and characteristics; review appeal deadline on the notice. |
Someone says Cobb reassesses only every three years |
Outdated assumption. |
Cobb says property may be revalued annually; there is no fixed three-year reassessment schedule. |
2026 tax estimate changes later |
Current estimator still uses prior adopted millage. |
Use the final Tax Commissioner bill once issued. |
City taxes missing from estimate |
Cobb estimator covers county-side taxes, not municipal tax bills. |
Contact the applicable city tax office when the parcel lies inside a municipality. |
Deed not found by parcel search |
Indexing/search route mismatch. |
Try owner name, instrument number, book/page, legal or record-date search. |
Parcel line conflicts with fence |
GIS is not a boundary survey. |
Review recorded plats/deeds and obtain a survey if the exact line matters. |
Appeal mailed at deadline but office says late |
Private postage-meter date is not accepted as USPS proof. |
Use USPS postmark/cancellation or documented hand delivery for deadline-sensitive filings. |

Personal PropertyCobb County Assessor Property Search FAQs
How do I search Cobb County property records by address?
Use the Cobb Tax Assessor’s property-search system and select the location-address search. When an address is difficult to find, Cobb’s address helper recommends entering only the house number and street and leaving out the apartment or unit, city, state and ZIP code.
Can I search Cobb County property records by owner name?
Yes. Cobb’s linked property-search system provides an owner-name search. Start with a distinctive owner or entity name, then verify the result by situs address and parcel number before relying on it.
How do I search a Cobb County parcel number?
Choose the parcel-number option in the official property-search system and enter the current parcel ID exactly as it appears on an assessment notice or prior county record. Save that number because it is useful for tax estimates, GIS, deeds and Assessor support.
What percentage of market value is assessed in Cobb County?
Georgia generally assesses taxable property at 40% of fair market value. For example, a $400,000 fair market value produces a $160,000 gross assessed value before applicable assessed-value exemptions and millage calculations.
When were Cobb County 2026 assessment notices mailed?
Cobb County mailed its 2026 Commercial, Residential and Personal Property Annual Notices of Assessment on June 5, 2026.
What was the normal Cobb County property appeal deadline for 2026?
Georgia allows 45 days from the mailing date of the Annual Notice of Assessment. Because Cobb mailed the 2026 notices on June 5, the ordinary 2026 appeal period ended July 20, 2026. Use the deadline on your own notice if you received a different or later appealable decision.
Is a Cobb County Taxpayer Return the same as an assessment appeal?
No. A Real Property Taxpayer Return is normally filed from January 1 through April 1 to report the owner’s asserted January 1 value or relevant property changes. An assessment appeal is filed after an appealable assessment notice or decision. Cobb explicitly treats the return and appeal as different procedures.
When will Cobb County 2026 property-tax bills be mailed and due?
Cobb’s current 2026 assessment guidance says the Tax Commissioner expects to mail property-tax bills around August 15 and that they will be due around October 15. Follow the exact date printed on the actual bill.
Why does the Cobb 2026 tax estimator still use 2025 millage rates?
The official 2026 estimator currently states that its estimate is based on 2025 adopted millage rates. The final 2026 bill can change after the applicable 2026 rates and tax digest are finalized, so use the estimator for planning rather than as the final amount due.
Where can I find a Cobb County deed or plat?
Use the Cobb Superior Court Clerk’s LandmarkWeb land-record system. It supports searches including name, document, book and page, parcel ID, record-date range, instrument number and legal information. Cobb Assessor FAQs direct property owners to the Clerk for deed and plat records.
Start With the Parcel, Then Use the Correct Office
Search the Cobb Assessor record by owner, address or parcel; confirm the parcel and 2026 values; then move to the Tax Commissioner for homestead, bills and payments or to the Superior Court Clerk for recorded deeds and plats.
For any deadline-sensitive appeal or changing 2026 tax figure, use the actual county notice, current estimator and official Cobb page linked beside that workflow rather than relying on an older annual deadline or prior-year millage rate.
