How Gwinnett Property Tax Works

Gwinnett Property Tax funds schools, roads, fire services, libraries, courts, and the county government. The county is one of the largest in Georgia and stretches across metro Atlanta with cities like Lawrenceville, Duluth, Norcross, and Suwanee.

The system has four main parts:

• The Board of Assessors sets the value of every parcel each year
• The Board of Commissioners and city councils set the millage rate
• The Tax Commissioner sends the bill and collects the payment
• The Tax Commissioner applies homestead exemptions and other relief programs

Millage Rates and Your Tax Bill

A mill is a tax rate that equals $1.00 for every $1,000 of assessed value. Gwinnett Property Tax uses a total millage that includes the county, schools, bonds, recreation, detention center bonds, and city portions when you live inside a city limit.

The county general millage rate sits at 6.95 mills and the rollback rate is 6.607 mills. When the digest grows, the county must hold public hearings before raising revenue above the rollback figure.

Property Tax Exemptions Homeowners Can Claim

Georgia law lets property owners lower their tax bill with several exemptions filed in Gwinnett County. Each exemption cuts the taxable assessed value, which lowers the total bill dollar for dollar.

There is one single application for all Gwinnett exemptions and the Tax Commissioner accepts them year round. To keep the exemption each year, you must apply by the deadline printed on your annual Notice of Assessment.

Filing a Homestead Exemption in Gwinnett County

A homestead exemption applies to your main home and lowers the taxable value. Once approved, it stays on the parcel until you sell, transfer, or stop using the home as your primary residence.

You can file in three ways:

• Apply online through the Gwinnett Tax Commissioner website
• Mail the form to the Tax Commissioner office at 75 Langley Drive, Lawrenceville, GA 30046
• Visit the office in person during business hours

You will need a Georgia driver license or state ID with the property address, a vehicle registration with the same address, and a voter registration card if you vote in the county. Refer to the Tax Commissioner for current processing times.

Reading Your Annual Assessment Notice

The Gwinnett County Board of Assessors mails annual Notices of Assessment every spring. In 2026, the office mailed approximately 311,000 notices to residential and commercial property owners.

Your notice lists four key numbers:

1. The fair market value, which is what the assessor thinks the property would sell for
2. The assessed value, which equals 40% of fair market value for residential parcels
3. The previous year value for comparison
4. The exemption amounts and the taxable value used to compute the bill

If the assessed value jumped, check for new construction, room additions, deck permits, or local sales the assessor may have used. A jump without a physical change often signals a market shift and may be a good reason to appeal.

How to Appeal Your Property Tax Assessment

You have 45 days from the date printed on the notice to file an appeal. Filing late means you accept the new value for the year, so mark the deadline on your calendar as soon as the notice arrives.

Follow these steps to file an appeal in Gwinnett County:

1. Download the state form PT-311A from the Georgia Department of Revenue
2. Fill in parcel number, owner name, and the value you want the Board of Equalization to set
3. Attach evidence such as comparable sales, photos, or a recent appraisal
4. Submit the form online through the Board of Assessors site or mail it to 75 Langley Drive, Lawrenceville, GA 30046
5. Wait for a hearing date, which is scheduled after the Board of Equalization receives your appeal

A successful appeal reduces the taxable value for the year and can lower your bill for every year until the next reassessment. Comparable sales from the same neighborhood or subdivision carry the most weight with the board.

Property Tax Payment Deadlines

The Gwinnett County Tax Commissioner mails tax bills in the fall of each year. Bills cover the current year and must be paid by the due date printed on the front of the bill to avoid penalties.

You can pay using any of these methods:

• Online with a bank card or eCheck on the Tax Commissioner website
• By mail with a check or money order to the mailing address on the bill
• In person at the Tax Commissioner office at 75 Langley Drive, Lawrenceville, GA 30046
• At a partner drop box or kiosk in participating cities

The Tax Commissioner may charge a fee for card payments. Check the current fee schedule on the bill or the official site before you pay.

Penalties for Late Property Tax Payments

Missing the deadline in Gwinnett County triggers late fees that grow each month the bill stays unpaid. The Tax Commissioner adds interest at the state-set rate along with a collection cost on top of the tax owed. Contact the Tax Commissioner for the current penalty and interest schedule.

Paying on time protects your credit, your title, and your homestead exemption status. Set a reminder for the due date or sign up for email alerts on the Tax Commissioner website.

Tax Lien Sales in Gwinnett County

A tax lien sale is a public auction the county uses to recover unpaid property taxes. The Tax Commissioner publishes a list of delinquent parcels each year and sells liens to the highest bidder, who then has the right to collect the debt plus interest.

The lien sale process generally works in this order:

1. The Tax Commissioner identifies parcels that are seriously past due
2. The office publishes a public notice before the sale
3. Bidders register with the Tax Commissioner and place a deposit
4. The county auctions liens to the highest bidder on the published date
5. The property owner has a redemption period to pay the debt, fees, and interest

If the owner does not redeem, the lien holder may file for a tax deed and take ownership of the parcel. To stop a sale, pay the full amount plus all fees before the auction begins.

Refund Process for Overpaid Property Taxes

Sometimes a property owner pays a bill based on a value that the Board of Equalization later lowers. In that case, the Tax Commissioner issues a refund for the difference.

To request a refund, follow these steps:

• Confirm the appeal outcome and the new assessed value
• Check your payment history on the Tax Commissioner website
• File a written refund request with the Tax Commissioner office
• Include the parcel number, refund amount, and a copy of the equalization decision
• Wait for the office to verify and process the refund

Refunds on homestead parcels may apply to the current year and the next year if the millage rate stays the same. Overpayments caused by escrow account errors often resolve with a phone call to your mortgage company.

Commercial vs Residential Property Tax Rates

Gwinnett County sets the same millage rate for every parcel type, but commercial parcels do not get the standard homestead exemption. Commercial owners often pay a much higher tax bill for the same market value.

Commercial owners can appeal each year with income, expense, and rent data. Brokers and investors often hire a tax consultant to file appeals because commercial bills are usually larger and the savings justify the fee.

Property Tax Relief Programs in Gwinnett

Several programs help older adults, disabled residents, and long-time homeowners keep their tax bill stable. The Value Offset Exemption is the most popular program because it generally prevents an increase in the county portion of the bill even when property values rise.

Other relief options include:

• Senior school tax exemption for owners 62 and older
• Disability exemption for owners with a documented disability
• Veteran exemption for honorably discharged veterans
• Floating homestead for homeowners who move within the county
• Hardship deferral for owners facing financial difficulty

To apply, file the standard homestead form and mark the boxes for each program you want. The Tax Commissioner reviews the file and notifies you by mail once the exemption is in place.

Accessing Property Tax Records Online

Property records in Gwinnett County are public and free to search. Buyers, sellers, and investors use the records to check tax history, ownership, and any open liens before closing on a deal.

You can pull records from three main sources:

• The Board of Assessors Property Ownership Database at https://www.gwinnettcounty.com/government/departments/county-administrator/assessor/property-ownership-database
• The Tax Commissioner site to view bills and payment history
• The Clerk of Superior Court site for deeds, liens, and recorded plats

Each tool covers a different part of the property file. Use the assessor site for value and exemption data, the Tax Commissioner site for bills, and the Clerk of Courts site for title records.

Role of the Board of Assessors

The Gwinnett County Board of Assessors is the office that sets the value of every parcel in the county. The board works under Georgia law, which requires the fair market value as the basis for property taxation. The tax commissioner does not determine property value and has no authority over that process.

The board handles several key duties each year:

1. Reviews sales data and updates the property record for every parcel
2. Mails annual Notices of Assessment to every owner of record
3. Forwards value appeals to the Board of Equalization
4. Maintains the property ownership database for public search

The board does not set the millage rate or send tax bills. Those duties belong to the Board of Commissioners and the Tax Commissioner. Homestead exemption applications are processed by the Tax Commissioner, not the Board of Assessors.

Role of the Clerk of Superior Court

The Gwinnett County Clerk of Superior Court records every real estate document that affects a parcel. Deeds, mortgages, liens, plats, and easements all pass through the Clerk office before they affect the title.

The Clerk office provides public access to recorded documents through local and statewide systems. You can search by name, parcel number, or document type. The state site covers every county in Georgia, while the local site focuses on Gwinnett records and is often faster for in-county searches.

Contact, Local Details, and Map

For tax bills, exemption filing, and payment questions, contact the Tax Commissioner. For property values, assessment notices, and appeals, contact the Board of Assessors. For deed, lien, and title questions, contact the Clerk of Superior Court.
