Every listing sheet in Canton carries a line that reads something like "Current Taxes: $2,140." It looks like hard information. It is actually a snapshot of someone else's paperwork: someone else's exemption, someone else's filing date, and in plenty of cases someone else's decade-old assessed value. The bill that lands in your mailbox after you close on that same house can run hundreds of dollars higher, sometimes more, and the gap has nothing to do with the millage rate moving. It has to do with what happens to a homestead exemption the moment a house changes hands. Nothing carries over.
The Freeze Belongs to Whoever Filed For It
Canton offers its own floating homestead exemption, separate from anything the county or state does. The city caps the growth in a homesteaded property's taxable value at whichever is lower, 3 percent or the rate of inflation, according to the city's own millage rate page. Once a homeowner files and that freeze locks in, their assessed value creeps upward slowly and predictably, no matter what the house next door sells for.
That freeze is personal, not permanent. Sell the house and the base year resets. Cherokee County recalculates the assessed value at 40 percent of current fair market value, and whatever gap the seller had quietly stopped paying for years disappears the day escrow closes.
The city's exemption is only one of three layers a Canton homeowner can end up under. Cherokee County runs its own separate floating homestead, one that freezes assessed value on the county maintenance and operations and fire district portions of the bill the year a homestead is first granted, a mechanism the county lays out on its own property tax communications page. In 2025, the state added a third layer through House Bill 581, a statewide floating exemption that specifically caps growth on the fire district millage. None of the three transfers with the deed. All three start over on the day of the sale, for whichever owner files next.
| Exemption Layer | What It Caps | Transfers at Sale |
|---|---|---|
| City of Canton Floating Homestead | Growth in city taxable value, capped at the lower of 3% or inflation | No, resets to current fair market value |
| Cherokee County Floating Homestead | Assessed value freeze on county M&O and fire district taxes | No, resets to current fair market value |
| Statewide HB 581 Floating Exemption | Additional cap layered on the fire district millage | No, resets to current fair market value |
The city also offers a senior tax exemption that removes up to $280,000 of a home's fair market value, or $112,000 of assessed value, for owners 62 and older. That one has its own filing requirements and doesn't factor into most move-up or first purchase math, but it's worth knowing it exists on the same page as the floating exemption, since both show up on the same city document.
What the Rate Actually Did This Year
None of this is about Canton's millage rate spiking. In fact, the opposite happened. The city advertised a 2026 rate of 6.000 mills back in June, a move that triggered three required public hearings under Georgia law, held July 2, July 16, and August 6. The advertised number was a ceiling, not a decision. City Manager Billy Peppers said as much when the rate was first advertised: "Advertising this rate protects the City's timeline and gives Council the ability to consider all available information before making a final decision."
That's exactly what happened. When Council approved the FY2027 budget in September, it held the city's millage rate at 5.250, the same rate the city had carried all year and, per the city's own materials, the lowest in Canton's history. It did that even though Cherokee County raised its fire district millage from 2.888 to 3.023 mills, adding roughly $728,000 in fire service costs the city absorbs because Canton contracts out its fire protection rather than running its own department, a detail confirmed in the city's FY2027 budget announcement.
The county government, a separate taxing body from the city, adopted its own combined rate of 8.999 mills in early August, covering the county's general fund, fire fund, and parks bond. So the rate landscape for 2026 is genuinely stable on the city side. If your Canton tax bill differs meaningfully from the number on the listing sheet, the rate isn't why. The reset in assessed value is.
Filing Got a Little More Forgiving
Georgia changed the mechanics of this process for the 2026 tax year through Senate Bill 566. Historically, a new owner had to file for their own homestead exemption by April 1 of the year following purchase or wait an entire extra year. Under the new rule, homeowners can now file anytime up through the same 45-day window they'd use to appeal their assessment, which gives buyers who close later in the year, or who simply miss the April 1 date, a second chance without losing a full tax cycle.
Cherokee County's assessment notices start mailing around June 15 each year, and the 45-day clock on both the appeal and this expanded filing window begins on the date printed on the notice, not the day it actually reaches the mailbox. Chief Appraiser Steve Swindell framed the broader intent of the law this way in comments to the Tribune Ledger News: "These changes are intended to help taxpayers better understand their property assessments, exemptions, and overall tax responsibilities." The filing itself is still something a new owner has to initiate. Nobody transfers it for you, and nobody reminds you twice.
What This Means If You're Comparing Canton to Somewhere Else
If you're weighing a resale in downtown Canton against a comparable home in a neighboring suburb, the "current taxes" figure on either listing tells you what the seller pays, not what you will. A seller who has owned and homesteaded a property since 2016 could be sitting on an assessed value that's grown a few percent a year while the surrounding market moved much faster. Buy that house and your first full tax year is calculated fresh, at 40 percent of the fair market value the county assigns after the sale, before any exemption of your own has had a chance to freeze anything.
Two practical implications follow. First, when you're building a monthly payment estimate, run the math off the home's current fair market value and the applicable millage rates rather than the seller's stated tax line. Second, file your own homestead exemption as soon as you're eligible, since it's the one lever that's actually yours to pull, and the 2026 rule change gives you a wider window than buyers had in prior years if you close outside the April 1 deadline.
New construction sidesteps the gap almost entirely, since a newly built home is assessed at current fair market value from its first tax year rather than inheriting someone else's multi-year freeze. That's not a reason to prefer one over the other, just a different starting point worth knowing before you compare two very different "current taxes" lines side by side.
Do I inherit the seller's homestead exemption when I buy a Canton home? No. The exemption and any frozen assessed value belong to the person who filed for them and end at the sale. You have to file your own after closing.
When do I need to file my own exemption? The traditional deadline is April 1 of the year after your purchase. Under the 2026 rule change, you can also file anytime through the 45-day window tied to your own first assessment notice, which typically arrives starting mid-June.
Does the city's decision to hold the millage rate at 5.250 mills affect what I'll owe? Only at the margins. The rate itself stayed flat for FY2027. What actually drives the difference between a seller's bill and yours is the reset in assessed value that happens at every sale, not a change in the rate applied to it.
Property tax mechanics like these rarely show up on a listing sheet, and they're exactly the kind of detail worth walking through before you write an offer, not after your first bill arrives. If you're comparing Canton to another North Atlanta suburb or want a clearer read on what a specific property's tax picture will look like once it's yours, The Trivon Group is a good place to start that conversation.
