Cobb County property taxes are easier to handle when you verify the parcel, bill year, exemption status and payment route before you pay.

This guide explains how to search and pay Cobb County property tax, read the bill, understand the October deadline, check exemptions, handle appeals and avoid late-tax mistakes. Use the official Cobb County tools only when you are ready to take account-specific action.
Quick Answer
To handle Cobb County property tax, start with the official Cobb Tax Commissioner property tax tools. Search or reprint the bill, confirm the parcel ID, owner, tax year, due date and balance, then pay online, by mail, by phone, in person or through an official drop box.

Cobb Tax Commissioner vs Board of Tax Assessors
Cobb County property tax tasks are split between offices. Knowing the difference helps you get the right answer faster.
| Office | What It Handles | Use It When | Official Link |
|---|---|---|---|
| Cobb County Tax Commissioner | Bills, collects and distributes ad valorem property taxes. Handles payment routes, receipts, delinquent taxes, homestead processing and tax sales. | You need to pay, reprint a bill, check a payment, ask about late taxes or verify a tax sale notice. | Property Tax Division |
| Cobb County Board of Tax Assessors | Sets taxable property values and handles assessment notices, property records and assessment appeals. | You disagree with value, classification, parcel details or assessment notice information. | Board of Tax Assessors |
| City tax offices | Municipal property tax bills for certain cities inside Cobb County. | Your property is inside a city that sends a separate city tax bill. | See city note |
Simple rule: payment problem = Tax Commissioner. Value or assessment problem = Board of Tax Assessors. City bill problem = city tax office.

City Property Tax Warning Inside Cobb County
CobbTax explains that the cities of Acworth, Austell, Kennesaw, Mableton, Marietta, Smyrna and Powder Springs handle city property tax billing for their respective cities. If your property is inside one of those city limits, you may receive both a Cobb County tax bill and a city tax bill.
Do not assume one bill covers everything: Paying your Cobb County bill may not pay a separate city property tax bill. Check your city tax office if your property is inside city limits.
Cobb County Property Tax Exemptions
A homestead exemption reduces the assessed value of a qualifying home, which can lower property taxes. Cobb County exemptions apply only when you own and occupy the property as your legal residence, and you can claim only one homestead exemption per household.
- Confirm you own and occupy the property as your primary residence.
- Make sure all applicants’ names appear on the deed.
- Gather Georgia residency proof, such as driver’s license and vehicle registration where required.
- Open the official CobbTax exemption page or online homestead application.
- Submit by the applicable deadline rules for the tax year.
- Keep confirmation and check later that the exemption appears on the tax record.
| Exemption | Who Should Review | Key Detail |
|---|---|---|
| Basic Homestead | Owner-occupants using the property as legal residence. | CobbTax lists this as a $10,000 exemption in county general and county school general tax categories. |
| Age 62 School Tax Exemption | Homeowners age 62 by January 1 of the current tax year. | CobbTax says this exemption is from all taxes in school general and school bond categories. |
| $22,000 Disability Exemption | Disabled homeowners meeting income and documentation requirements. | CobbTax lists income limits and proof requirements; review carefully before applying. |
| Age 65 $4,000 State Senior | Homeowners age 65 by January 1 who meet income rules. | CobbTax lists a $4,000 exemption with income limitation details. |
| Veteran Disability | Qualifying disabled veterans with VA documentation. | A VA letter and qualifying disability status are required. |
| Surviving spouse exemptions | Un-remarried surviving spouses or qualifying minor children under specific state rules. | Documentation is required; review the exact category before filing. |
Not eligible: You cannot apply for Cobb County homestead on a rental property or while claiming homestead in another county or state. False or duplicate claims can lead to penalties and interest.
Cobb County Assessment Appeals
If the problem is the property value or assessment, paying the bill is not the same as appealing the value. Cobb County assessment appeals are handled through the Board of Tax Assessors, and appeals can only be filed in response to an Assessment Notice.
- Open your Annual Notice of Assessment.
- Find the notice date and appeal deadline.
- Review the property value, exemption status and property details.
- Gather evidence such as comparable sales, property condition photos or record corrections.
- File through the official appeal route within the appeal window.
Appeal payment warning: CobbTax FAQ says you must pay at least the appeal amount by the due date to avoid a penalty. The Tax Assessors Office is not authorized to extend the payment deadline.
Delinquent Taxes, Tax Sale Notices and Excess Funds
If Cobb County property taxes are unpaid, act quickly. Tax sale, levy and excess funds issues can become time-sensitive. CobbTax specifically warns taxpayers to verify tax auction correspondence with the CobbTax Levy Department.
- Search the property tax account and confirm the unpaid year.
- Compare any notice with official CobbTax records.
- If the notice says your property may go to tax auction, call the Levy Department for verification.
- Ask what amount must be paid and what deadline applies.
- Keep all letters, receipts and confirmation numbers.
Excess funds note: CobbTax says you do not have to pay an asset recovery firm to claim excess funds. Use official CobbTax excess funds instructions instead.
If You Just Bought a Cobb County Property
New owners often get confused because the tax bill can involve a prior owner, closing credits, mortgage escrow, city tax billing and homestead deadlines. Do not assume your closing statement means the county bill is already paid.
- Find the parcel ID from your deed, closing statement or assessment record.
- Search or reprint the current Cobb County tax bill.
- Compare the bill with your closing statement and escrow setup.
- Check whether the property is inside a city that sends a separate tax bill.
- Apply for homestead if you own and occupy the home as your primary residence.
- Confirm your mailing address and future bill delivery.
If Your Mortgage Company Pays Your Cobb County Property Tax
Mortgage escrow does not remove your responsibility to make sure taxes are paid by the due date. CobbTax has stated that tax information is sent to mortgage companies for escrow accounts, but property owners remain responsible for ensuring taxes are paid on time.
- Search the tax bill online before the due date.
- Check whether the mortgage company payment has posted.
- Compare the tax amount with your escrow statement.
- Contact the mortgage servicer if payment has not posted near the deadline.
- Do not pay personally until you know whether an escrow payment is pending.
- Save official payment-status proof and escrow communication.
Documents to Keep Before and After Payment
Good records make it easier to solve payment disputes, exemption questions, appeals, escrow confusion or delinquent tax issues.
Parcel ID, bill copy, tax year, property address, owner name, exemption status and city tax status.
Online receipt, phone confirmation, check image, USPS proof, office receipt or drop-box record.
Georgia driver’s license, vehicle registration, proof of age, income proof, disability proof or VA documentation if required.
Assessment notice, comparable sales, photos, property record corrections, appraisal and appeal confirmation.
