Why the Tax Bill on a Duluth Listing Isn't the One a New Owner Pays
The Gwinnett County Tax Commissioner has posted a sample 2026 bill for a homesteaded house in unincorporated Gwinnett. It is dated September 8, 2026, for a home with a total value of $428,400. The county section shows $1,459.83 removed by the Value Offset Exemption, and county taxes come to $773.68 after exemptions. Below that, the Board of Education section shows a column for the statewide floating exemption with $0.00 in it. School taxes total $2,966.70, which the bill says is 79.32% of the home's ad valorem tax.
That bill shows how Gwinnett's protections are weighted. The best-known freeze in Gwinnett is real and generous, but it covers the county share, and on a homestead bill the school share is far larger. When the tax line on a Duluth listing looks lower than a buyer expects, the reason usually has more to do with who the seller is, how long they have owned the home, and a state credit that applies to 2026 only.
A home inside Duluth city limits pays three taxing bodies, and each one made its own choice about Georgia's 2024 floating homestead exemption, HB 581. That law limits yearly increases in a homestead's assessed value to inflation.
| Taxing body | 2026 rate | How it treats a homestead's rising value |
|---|---|---|
| Gwinnett County government | 6.95 mills general fund | Opted out of HB 581 on Feb. 18, 2025. Uses its own Value Offset Exemption, in place since 2001, which holds county assessed value at a base year with no inflation adjustment |
| Gwinnett County Public Schools | 18.70 mills operations, 1.45 mills bond | Announced in 2025 that it intended to opt out. The school line on the 2026 sample bill shows no floating exemption |
| City of Duluth | 6.551 mills | Opted in to the floating exemption as of tax year 2025. Assessed value increases are limited to CPI, listed at 2.7% |
The Gwinnett Tax Commissioner's 2026 rate table lists 31.60 combined mills for the Duluth district before the city's rate. Adding the City of Duluth's 6.551 mills gives a nominal 38.151 mills before exemptions. The two school rates make up more than half of that total. The school portion is also charged on current assessed value, while the county portion is charged on a frozen base.
Gwinnett County has published its own example of how the freeze works over time. It follows a Suwanee home whose county base was set in 2013. Between 2021 and 2024, its market value rose from $420,300 to $746,500.
The county calculates that the Value Offset Exemption saved that owner $5,691.11 over the four years. The same page also says that most of the property tax increases Gwinnett homeowners have seen in recent years came from school and city taxes.
The freeze ends when the house changes hands. A homestead exemption "continue[s] automatically unless there is a change in ownership," according to the Tax Commissioner's brochure. The brochure also says the Value Offset Exemption sets the base value at Jan. 1 of the year before the application year. A buyer who files for homestead gets a new county base tied to their own application, not the seller's 2013 or 2017 number.
Duluth's city cap works the same way. HB 581 says the floating exemption does not transfer to a later owner. For a new owner, the base is the assessed value from the tax year before the exemption is first granted. The law also treats the most recent arm's-length sale price as the most the assessor can use for fair market value in the next tax year.
So when a Duluth home sells, the county and city protections reset. The school portion, which is the largest share, does not change, because it already follows current value for most owners. For a typical owner who is not a senior, the difference between their bill and a buyer's bill comes mostly from the county and city lines.
A much bigger gap appears when the seller qualifies for Gwinnett's senior school exemption, which the county codes as L5A. It removes 100% of Gwinnett County Public Schools taxes on a qualifying home and up to one acre. Owners qualify at age 65 or older, or if they are 100% totally and permanently disabled. There is an income limit, set at $124,648 for 2026, and applicant and spouse income are counted together. The Tax Commissioner's brochure says the exemption covers all school and school bond tax.
On the sample bill above, the school share was 79.32% of ad valorem tax. A seller with L5A can therefore show a tax history that has very little in common with what the next owner will pay. Neither the listing nor the tax record has to say which exemption caused the low number.
The second factor is limited to 2026. Georgia's Department of Revenue says HB 439, signed May 12, 2026, put $950 million in the Amended FY2026 budget for a Homeowner Tax Relief Grant. The grant reduces a qualified homestead's assessed value by $18,000. It appears as a credit on the bill, not as a check, and it cannot be larger than the taxpayer's liability. On the sample Gwinnett bill, the credit totaled $479.70 and was not applied to the school bond line. A buyer comparing a 2026 bill to a later year should treat that line as funded by the state for a single budget year.
The rate itself also matters. At its August 10, 2026 hearing, Duluth proposed keeping its 6.551-mill rate. The city's packet says that is 0.185 mills, or 2.91%, above the rollback rate and would bring in about $525,644 in reassessment revenue. Citizen Portal's coverage of the August 24 meeting reports that the council adopted it. A rate that stays flat while assessments rise still raises taxes on any home whose city assessment is above its capped base.
Duluth homeowners get two separate property tax bills, and the timing matters to anyone closing this fall.
The Tax Commissioner's brochure says the owner on Jan. 1 is legally responsible for the full year's taxes. If a property changes hands after Jan. 1, both the Jan. 1 owner and the new owner receive a bill. The Tax Commissioner does not decide who owes what, and the buyer and seller divide the taxes between themselves, usually at closing. A home closing after November 15 and before December 15 falls between those two due dates, with the county bill due and the city bill still open. That split is based on the seller's exemptions for the current year, not the buyer's.
To qualify for homestead, a buyer has to own the home and live in it as their primary residence on January 1. The sources give different filing deadlines. The Tax Commissioner's brochure, revised in August 2025, and the City of Duluth's FAQ both say April 1. The Tax Commissioner's current homestead page says to apply by the appeal deadline printed on the Notice of Assessment, which the Assessor's Office mails in the spring. According to the City of Duluth, a homestead application filed through Gwinnett posts to the owner's city account automatically.
This post is general information, not legal, tax or financial advice. Exemption eligibility and closing prorations depend on each owner's circumstances, so confirm yours with the Gwinnett Tax Commissioner, a tax professional or your closing attorney.
Does Gwinnett's school district cap assessed value increases for homesteads? Gwinnett County Public Schools announced in 2025 that it intended to opt out of HB 581. On the 2026 sample bill, the school line shows no floating exemption. Under HB 92, a district that opted out may rescind that decision by March 1 of a given year for tax years 2026 through 2029.
Will the Homeowner Tax Relief Grant show up on next year's bill? The 2026 grant came from the Amended FY2026 budget under HB 439.
Does refinancing reset the county freeze? The Tax Commissioner's brochure says exemptions should not be affected by refinancing unless the name on the deed changes.
