When Tax Bills Are Mailed

You will be mailed your bill each year by August 15.  Your payment must be postmarked by October 15.  We do not accept metered or kiosk postmarks as proof of timely mailing.


Mortgage Companies

Usually, your mortgage company will have an escrow account set aside for paying property taxes.  Once the account is established, they send us a notice stating they will be paying your property taxes.  We then send both you and your mortgage company a bill every year.

While your mortgage company may be helping you in paying your taxes, ultimately you must make sure your taxes are paid on time no matter who is handling the payment.  In the event you both pay taxes on the same property, we will refund the extra payment back to the payer.


How You Can Pay Your Taxes

You can pay your taxes or reprint your bill online using e-checks, debit and credit cards.  Convenience fees for cards will apply.  There are no convenience fees for paying by e-check.

Credit/debit cards payments are done using a PayPal module available within our website.  This module is encrypted and meets current internet security standards.


You can mail your payment with a check or money order.  Make checks payable to the Cobb County Tax Commissioner.

      Send your payment to:

           Cobb County Tax Commissioner
           P.O. Box 100127
           Marietta, GA 30061-7027

You can also visit us or any of our service centers in-person.


Understanding Your Tax Bill

Each property tax bill is formatted in the same way.  Knowing how to read your tax bill will give you a better idea of your current exemption status, your parcel ID, your tax district, among other items.

Your property tax bill looks like this:

Lost Bills

If you lost your bill, we can mail you a new one.  To do so, we need the parcel ID for your property.  You can also reprint your bill online and attach it to your payment if you wish to use a physical check or money order.

You can always pay your taxes online without your bill.


Partial Payments

We do accept partial payments.  If you have not paid your bill in full by the time your taxes are due on October 15, we apply late fees and interest to the remaining balance.  Paying some of your taxes is better than paying none of your taxes.


Late Payments

Your payment must be U.S. postmarked or received by October 15.

If you do not pay on time, you will be charged:

  • 5% of your taxes.
  • interest every month you are late.

If you do not pay your taxes at all, your property may be subject to a Fi. Fa. (tax lien) and eventually put up for tax sale.  Find out more about Fi. Fa.'s and tax sales on our delinquent taxes page.

If your property is subject to a Fi. Fa. you will also be charged:

  • $21.00 on taxes less than $100.00
  • or $31.00 on taxes greater than $100
  • Any administrative fees associated with issuing the Fi. Fa.


Can We Waive Late Fees?

No, unfortunately, we cannot.  If you did not get your bill, you can always print your bill online or contact us.  We are more than happy to reprint any bill you are missing.


Address Changes

We have a change of address form available online.  Fill this out and e-mail it to us at  If you need a homestead exemption removed, please notify us on the form.

Please note, tax billing records displayed through our website reflect ownership and other records as they existed at the time each year's particular bills were issued, therefore new address changes do not affect previous records in our Search and Pay Taxes portal.


Prorated Taxes

We do not prorate taxes.  Instead, you are charged for the full year even if you have only owned your property for part of the year.  Taxes are attached to the property itself rather than the current owner.  That means that when you purchase a property, you also inherit the previous owner’s taxes.

That said, many closing attorneys include tax payments in the final settlement.  Please contact your closing attorney to verify if your taxes have already been accounted for.


Closed Businesses and Taxes

If you closed your business or sold business assets after January 1 of the current year, you still have to pay taxes.  Make sure you notify the Board of Assessors that you have closed or sold property so they know not to assess your business's personal property.
