The office name matters because Cobb County has different tax offices for different jobs. The Tax Commissioner collects, processes payments, handles tax bills, supports homestead-related tax functions, manages property tax sales and operates motor vehicle tag services. The Board of Tax Assessors determines taxable value, sends annual assessment notices and handles value appeal routing. If your bill amount looks wrong because the property value is wrong, call the Assessor. If you need to pay or confirm posting, call the Tax Commissioner.

How to Search or Pay a Cobb County Property Tax Bill
Most Cobb property tax searches begin with an address, owner name, parcel number or bill information. Use the official CobbTaxPayments portal for payment and the Board of Tax Assessors tools for value and parcel research.
| What you need | Best starting point | Before paying, verify |
|---|---|---|
| Pay a current property tax bill | CobbTaxPayments.org | Owner, address, parcel, tax year and bill amount. |
| Check assessed value | Cobb Board of Tax Assessors | Notice year, fair market value and exemption estimate. |
| Pay by phone | 1-866-PAY-COBB | Bill information and confirmation number. |
| Delinquent payoff | Call 770-528-8623 if listed by portal notice | Penalty, interest, fees and tax sale status. |
If the bill does not appear online, try a shorter address search, check owner spelling, remove punctuation, use the parcel ID, or call the Property Tax Division. Do not pay a similar-looking account unless the property address and tax year match your actual bill.
Cobb County Tax Assessor vs Tax Commissioner
The Cobb County Tax Commissioner collects and disburses property taxes. The Cobb County Board of Tax Assessors establishes fair market value, sends assessment notices and handles property value appeal routing.
| Your question | Correct office | Why it matters |
|---|---|---|
| I need to pay my property tax bill. | Tax Commissioner | The Tax Commissioner handles collection and payment processing. |
| My 2026 Notice of Assessment value seems too high. | Board of Tax Assessors | The Assessor handles value and appeal questions. |
| I want to estimate my tax bill. | CobbTax.gov estimator and Assessor notice | The notice estimate is not final until millage rates are adopted. |
| I need a tag, title or vehicle registration. | Tax Commissioner Motor Vehicle Division | The Motor Vehicle Division acts as tag agent for Georgia DOR services. |
Cobb’s 2026 assessment notice information explains that properties are assessed at 40% of fair market value under Georgia law, and the notice estimate uses current exemptions and previous-year millage rates. Your actual tax bill may differ after local taxing authorities adopt new rates.

Georgia DOR explains that homestead applications may be made up to April 1 of the first year for which the exemption is sought, and failure to apply is considered a waiver of the exemption.
CobbTax.gov provides homestead resources, and CobbTax social updates have reminded homeowners that April 1 is an important deadline. If you bought a home, moved into a primary residence, turned 62 or believe you may qualify for a school tax exemption, senior exemption or other local benefit, check the official CobbTax homestead page before the deadline.
Official source: Georgia DOR Cobb County property tax facts and CobbTax.gov.New homeowner
Check homestead eligibility after the home becomes your primary residence. Do not assume the seller’s exemption transfers to you.
Senior or school tax exemption
Cobb has exemption-related resources. Ask the Tax Commissioner or Assessor which exemption path applies to your situation.
Deadline reminder
April 1 is a critical deadline for many Georgia homestead exemption situations. Verify exact Cobb requirements before relying on an estimate.
Cobb County Tag Office, Vehicle Registration and TAVT Questions
Georgia DOR explains that vehicle owners renew registration and pay applicable ad valorem tax every year during the 30-day period ending on their birthday, and newly acquired vehicles must be registered within 30 days.
Cobb County’s Tax Commissioner also operates Motor Vehicle Division services. If your search for “Cobb County tax collector” is really about a tag, title, renewal, birthday registration period, TAVT, emission requirement or tag office wait time, use the motor vehicle division rather than the property tax payment portal.
Official source: Georgia DOR Cobb County property tax facts and CobbTax.gov motor vehicle resources.Renew tags
Use CobbTax motor vehicle services for tag renewal and registration-related questions.
Birthday deadline
Georgia vehicle registration periods are tied to the birthday rule for many owners. Check your notice and official DOR rules.
Not property tax portal
Property tax bill search is not the same as tag renewal. Use the correct division before paying.
Late Cobb County Property Taxes, Delinquent Payoffs and Tax Sale Warnings
If your Cobb County property taxes are late or the property may be headed toward tax sale, do not guess the payoff from a screen snapshot. Contact the office directly for the current amount.
CobbTaxPayments.org specifically says delinquent payoff amounts should be handled by contacting the office directly at 770-528-8623 because additional penalties, interest or fees may not be reflected. CobbTax public notices also warn taxpayers to verify any correspondence about tax auction by contacting the CobbTax Levy Department.

Check current amount, penalties, interest and fees before paying. Do not rely on an old amount from a previous notice.

If a letter says your property is going to tax auction, verify it directly with CobbTax Levy before responding or paying anyone else.
Mortgage escrow issue
If your mortgage company should have paid, check the official bill status and ask the servicer for written proof of disbursement.
Cobb County Tax Receipt, Duplicate Bill and Payment Proof Checklist
A property tax receipt can matter for mortgage escrow disputes, refinancing, real estate closings, accounting, rental records, senior exemption follow-up, tax sale prevention or family financial records.
Payment proof should include
- Parcel ID or account number
- Property address
- Owner name
- Tax year
- Amount paid
- Payment date

Save extra records
