The short answer: Property taxes in Woodstock, Canton, and Acworth are based on 40% of your home’s assessed value, multiplied by the combined millage rates of your county, school district, and city. Woodstock’s median effective rate is about 0.95%, which is slightly below the Georgia median of 1.00%, but higher home values mean the typical bill is still about $3,500 a year. Filing a homestead exemption by April 1 lowers your taxable value on your primary residence, and a new state law (the HOME Act, SB 33) will cap how fast your homestead assessment can rise beginning in 2027.
I’m David Karp, Broker/Owner of Peachtree Realty Group, LLC. In 43 years and more than 500 transactions in real estate, property taxes are one of the most common “I wish I’d known sooner” topics I hear from buyers and sellers. Here is how the system works in plain English.
How are property taxes calculated in Cherokee County, GA?
Georgia taxes property in three steps:
Fair market value. The county tax assessor estimates what your home would sell for as of January 1.
Assessed value. Georgia assesses residential property at 40% of fair market value.
Millage rate. Each taxing authority (county, school district, and city, if you are inside city limits) sets a millage rate. One mill equals $1 of tax per $1,000 of assessed value.
For example, a home with a $450,000 fair market value has an assessed value of $180,000. Before exemptions, you multiply that $180,000 by your total millage rate, divided by 1,000. Because your school, county, and city rates all stack together, two homes with identical values can have different bills depending on whether they sit inside city limits or in unincorporated Cherokee County.
According to Ownwell’s local data, Woodstock’s median effective tax rate is about 0.95%, compared with 0.97% for Cherokee County, 1.00% for Georgia, and 1.02% nationally. The median Woodstock tax bill is about $3,521, because local home values are well above the national median. Source: Ownwell
What are the current tax rates in Woodstock?
Woodstock has been trending in the right direction for homeowners. The city’s maintenance and operations (M&O) rate for 2026 is 5.13 mills, plus 0.52 mills for the parks bond voters approved in November 2023. Source: City of Woodstock In 2025 the city council approved what its mayor described as the lowest Woodstock tax rate in at least 30 years. Source: Cherokee County Chamber of Commerce
Keep in mind that the city portion is only one slice. The largest share of most bills in this area goes to the school district, and Canton and Acworth (which sits in Cobb County) have their own rates. If you are comparing homes in different towns, ask for the actual tax bill, not just the listing’s estimate.
What is the homestead exemption, and how much does it save?
A homestead exemption reduces the assessed value of your primary residence before the millage rate is applied. Cherokee County’s standard exemption reduces assessed value by $5,000 for county maintenance and operations taxes and $2,000 for school taxes. Source: Cherokee Tribune Ledger Additional exemptions, including senior and other special exemptions, may be available depending on age, income, and local rules, so it is worth asking the tax assessor’s office what applies to you.
Some quick facts that matter:
Primary residence only. Rentals, second homes, and investment properties do not qualify.
You generally file once. Unless ownership changes or you make a significant improvement, you do not need to reapply every year.
The deadline is April 1. To receive the exemption for the current tax year, apply by April 1. Many exemption details change, so confirm the current figures with the assessor.
List everyone on the deed. Include all owners on the application so there are no eligibility problems later.
File with the county, not the city. Even for Woodstock addresses, exemptions are filed with the Cherokee County Tax Assessors office.
What is changing with Georgia’s new property tax cap?
This is the part most homeowners have not caught up with yet. In 2024, Georgia passed HB 581, which created a “floating homestead exemption” that limits how fast your taxable value can grow, tied to inflation. Local governments could opt out, and many did. About 68% of school districts and 30% of counties opted out statewide. Source: Tax Foundation The Cherokee County Board of Education was among those that opted out, saying the cap would reduce school tax revenue. Source: WSB-TV
In 2026, the legislature passed SB 33, the HOME Act, and Governor Kemp signed it on May 11, 2026. Starting in 2027, the inflation cap on homestead assessments applies to all counties, cities, and school districts, with no opt-out. The law also lets counties ask voters for a 1% local sales tax beginning in 2028 to fund additional homestead exemptions. The protections apply only to owner-occupied primary residences.

What does that mean in practice? Your taxable value will rise more slowly than your market value if the market is climbing. It is not a freeze, and it does not cap the millage rate, so your bill can still change if rates change. And it only helps if you hold a homestead exemption, which is one more reason to file on time.
What happens to property taxes when you buy or sell a home?
Taxes affect both sides of a transaction.
If you are buying: Do not assume the seller’s current tax bill is your future bill. A sale resets what the assessor sees as market value, and the seller may have had exemptions that do not transfer. Ask your agent to estimate taxes using the purchase price and your likely exemptions. Lenders also collect taxes into escrow, so the number affects your monthly payment.
If you are selling: Property taxes are prorated at closing, so you pay for the time you owned the home that year and the buyer pays the rest. Bills in Woodstock go out in the fall, typically mid-to-late October, and are due within 60 days. Source: City of Woodstock
If you are moving up or downsizing: Compare the tax bill, not just the price. Moving from an older home to a newer one at a higher value can raise your taxes more than you expect, while a smaller home in a lower-rate area may reduce them.
For context on the local market, Redfin reported a Woodstock median sale price of about $482,800 in the three months ending August 2026, down 3.4% from a year earlier, with homes spending about 48 days on the market.

Step-by-step: how to lower your Georgia property tax bill
Confirm you have a homestead exemption. Check your bill or the Cherokee County Tax Assessors’ records. If you bought in the last year, file before April 1.
Gather your documents. Typically a driver’s license, your deed or closing documents, and vehicle registration showing the property address.
File with the Cherokee County Tax Assessors office online or in person, and list every owner on the deed.
Ask about additional exemptions. Seniors and others may qualify for more. Ask what applies to your age and situation.
Review your assessment notice when it arrives. Notices typically go out in the spring and include an appeal window, so do not set it aside.
Compare your value to recent nearby sales. If your assessed value is higher than what similar homes sold for, you may have grounds to appeal.
File an appeal on time if needed. Deadlines are short, and missing them means waiting another year.
Re-check each year. Under the HOME Act, your homestead assessment growth will be capped starting in 2027, so make sure your exemption is on file.
