The short answer: Georgia property tax is calculated by taking 40% of a home’s fair market value (the “assessed value”), subtracting any exemptions such as the homestead exemption, and multiplying the result by the millage rate, where one mill equals $1 of tax per $1,000 of taxable value. For a Cherokee County home valued around $525,000, Cherokee County’s own 2026 presentation shows the county general fund portion alone at roughly $625 and the fire fund portion at roughly $553 for a homestead owner, before school, city, and other levies are added. Your actual total depends on your county or city, school district, exemptions, and the price you pay, so estimate the bill from the purchase price, not the seller’s current bill.
I’m David Karp, Broker/Owner of Peachtree Realty Group, LLC. In 43 years and more than 500 transactions, many in Woodstock, Canton, and Acworth, the property tax surprise is one I’ve seen catch otherwise well-prepared buyers, so here is how I walk clients through it.
How are property taxes calculated in Georgia?
Georgia uses a three-step formula, and it helps to see each step separately.
Fair market value. The county tax assessor estimates what your home would sell for.
Assessed value. Georgia taxes 40% of that value. A $525,000 home has an assessed value of $210,000.
Taxable value and millage. Exemptions are subtracted from the assessed value, and the remainder is multiplied by each taxing authority’s millage rate.
Cherokee County’s FY2026 millage presentation uses exactly this example. At a $525,000 median value, the 40% assessed figure is $210,000. The county’s homestead exemption of $88,659 for the general fund leaves a levy base of $121,341, which at the current general fund rate of 5.153 mills produces about $625. The fire fund, after a $18,528 exemption, applies to $191,472 and comes to about $553 at the current 2.888 mills. The parks bond debt service rate of 0.260 mills adds about $55 on this example (Cherokee County FY2026 Millage Rate Presentation).
Those three county lines are not your whole bill. School district taxes are typically the largest piece, and if you live inside a city limit, a city levy may apply too. That is why a property listing’s “tax” figure should always be treated as a starting point.
Did Cherokee County raise its millage rate for 2026?
The county’s presentation laid out several options for the general fund, ranging from the current 5.153 mills up to an advertised 6.348, with the fire fund options running from the 2.888 current rate to about 3.13. It notes that after exemption increases, the 2026 digest experienced a reassessment loss, which pushed the rollback rate above the prior year’s rate. At the median home example, the general fund options added anywhere from about $71 to about $145 a year compared with the current rate.
The presentation lists options and does not state a final adopted rate, and the final hearing and adoption were scheduled for August 4, 2026. Before you rely on any number, confirm the adopted rates with the Cherokee County Tax Commissioner or Board of Assessors. I would rather tell you that plainly than guess.
Why does your bill change when you buy a home?
This is the part buyers most often miss. The seller’s tax bill reflects the seller’s assessed value and the seller’s exemptions. When you buy:
Your assessment can reset toward the purchase price. If the seller has owned for years, the current assessment may be well below what you are paying.
The seller’s homestead exemption does not transfer. You have to file your own, and the application deadline in Cherokee County has been April 1 for the tax year. A homestead exemption generally only needs to be filed once unless ownership changes or major improvements are made, and every owner on the deed should be on the application (Cherokee Tribune).
Floating exemptions help after the first year. Cherokee County already has a floating exemption on county maintenance and operations that limits taxable value increases, and Woodstock, Holly Springs, and Mountain Park have floating exemptions as well. The state’s HB 581 added a statewide floating exemption that applies to fire district millage and to cities without their own exemption. School taxes are not covered by the county floating exemption.
How do you estimate property taxes on a home you want to buy?
Here is the process I use with buyers, in order.
Start with your likely purchase price, not the current assessed value.
Multiply by 0.40 to find the assessed value.
Subtract the exemptions you expect to qualify for, starting with the standard homestead exemption.
Look up the millage rates for the specific property: county, fire district, school, and city if applicable. The same street address can fall in a different combination than the home one road over.
Multiply taxable value by each rate and divide by 1,000, then add the lines together.
Add a cushion and divide by 12 to see the monthly escrow your lender will likely collect.
Ask your agent or lender to confirm against the county’s current digest before you finalize your budget.
How do property taxes compare across Woodstock, Canton, and Acworth?
Woodstock and Canton sit in Cherokee County; most of Acworth is in Cobb County, with a portion in Cherokee. That means two different county governments, school systems, and millage structures. Woodstock also has a city levy and a city floating exemption, while Canton has its own city taxes. Rather than quote a rate that may have changed, I tell clients to compare the full bill for the specific address, because two homes at the same price can have meaningfully different totals.
For context on the market itself, one local data source reported a Woodstock median sale price of about $457,500 and a median of 31 days on market as of late October 2026, with roughly four months of supply, a balanced market (Momentum Realty). That page had some internal inconsistencies, so treat it as directional rather than exact.
Can you lower your property tax bill?
Often, yes, in a few ways:
File your homestead exemption by the April 1 deadline.
Check for additional exemptions for seniors, disabled persons, and veterans.
Review your assessment notice when it arrives and appeal within the window printed on it if the value looks too high. Comparable sales are the strongest evidence.
Make sure every owner is on the exemption.
I’m not a tax attorney or CPA, so for specific tax advice, check with a qualified professional or the county.
What property tax mistakes do buyers and sellers make most often?
After four decades of closings, a few patterns repeat. Buyers anchor on the seller’s current tax bill, which may be years out of date and may include an exemption they will not inherit. They forget that escrow is collected at closing and then monthly, so a higher-than-expected bill changes both cash to close and the monthly payment. They compare two homes by list price alone and overlook that a different school or city levy can shift the annual bill by hundreds of dollars.
Sellers have their own blind spot. Property taxes are prorated between buyer and seller at closing, and in Georgia the bill is typically issued in the fall for the current year, so the timing of your closing affects who owes what. Your closing attorney will calculate the proration, but it helps to know it is coming. If you are selling to move up or downsize, run the numbers on the next home’s taxes before you commit, because a lower-priced home in a different jurisdiction can sometimes carry a similar or even larger bill than the one you are leaving.
My advice is calm and simple: get the address-specific numbers early, build a small cushion into your budget, and file your homestead exemption the first year you own. Those three steps prevent nearly every property tax surprise I have seen.
