Gwinnett County Property Tax Rate

Think that calculating your individual property tax rate is confusing? You’ll be pleased to learn that understanding the process for assessing and collecting is easier than you may have previously believed.

Determining your individual property taxes depends on several key variables. Below is a breakdown of those variables, and how to use them to calculate your Gwinnett County property taxes.

How are property taxes calculated in Gwinnett County, Georgia?

Each year, the Gwinnett Board of Commissioners votes on the county property tax rate (in mills) to use for calculating property taxes. In 2021, this rate remained unchanged from the previous year at 14.71 mills. Here, one mill equals a tax liability of $1 for every $1,000 of assessed value.

Gwinnett County property tax assessments are based on a relatively simple formula. After locating the fair market value of a home, it is used to determine the assessed value (which is 40 percent of the fair market value).

Below is the formula provided by the county for determining your individual property taxes:

Annual Property Tax = [(40% x Fair Market Value) – Exemptions] x Millage Rate

Annual Property Tax = [(.40 x Fair Market Value ) – Exemptions] x Millage Rate

Annual Property Tax = Assessed Value – Exemptions x Millage Rate

How much are property taxes in Gwinnett County?

Calculating what you’ll owe in property taxes is a matter of using the above formula with the correct figures for your individual situation. Although obtaining these figures can sometimes be challenging, they are needed for an accurate number that can be used for planning purposes.

Gwinnett County Property Tax Payments – Due Dates & How to Pay Your Tax Bill

Want the full rundown on how to pay your Gwinnett County property taxes? Learn everything you need to know as a new area homeowner.

For those who pay the county directly, Gwinnett County property tax bills for the current year are sent out in August. Homeowners are responsible for paying what they owe in full by October 15th.

One incredibly important difference between Gwinnett County and many other counties across the nation is that the county does not send property tax bills directly to mortgage companies. Typically, when an individual has an active mortgage on their home, property taxes are paid directly to the county by the mortgage company. Funds from a homeowner’s escrow account are used to cover the balance. However, those who owe property taxes to Gwinnett County are responsible for ensuring that their mortgage company has looked up and paid their current year property taxes.

Another highly important thing to note is that not everyone living in Gwinnett County will pay property taxes to the county. Instead, many residents pay the city in which they live. Cities that operate separately from the county set their own timelines for when bills are sent out, and when payment is due. For example, the City of Suwanee sends property tax notices in October, and requires payment by December 20th. Since every city is different, be sure to check the rules and deadlines for where you ultimately choose to reside.

What happens if you don’t pay your Gwinnett County property taxes on time? Each month, a penalty of 0.52% interest is added onto your total bill. If your balance remains unpaid after 120 days, a 5% penalty is added. An additional 5% is added for every 120 days that elapses.

If you cannot pay the balance in full by the deadline, the Tax Commissioner’s office accepts partial payments. While penalties and interest do accrue on the unpaid balance that remains after the payment deadline, making partial payments is ideal to avoid larger penalties. You can make payments online using your bank account, VISA, MasterCard, Discover, or PayPal.

Prefer to pay in-person or by mail? You can mail a check or money order to Gwinnett County Tax Commissioner, Department of Property Tax, P.O. Box 372, Lawrenceville, GA 30046-0372. You can also submit a check or money order at one of the drop boxes at any one of the five tag offices.
