A Gold Peach Realty luxury home guide · (770) 283-1223
Alpharetta · Milton · Johns Creek · South Forsyth
An Alpharetta, Georgia mailing address can belong to four different governments: the City of Alpharetta, the City of Milton, the City of Johns Creek or unincorporated south Forsyth County. Each sets its own tax rate, and the line also decides the school district. This guide sorts the five luxury areas behind the address, prices the tax by jurisdiction and shows Gold Peach Realty listings.

One address, four jurisdictions
“Alpharetta, GA” is a postal name. Behind it sit the City of Alpharetta, the cities of Milton and Johns Creek, and unincorporated south Forsyth County, each with its own tax rate, zoning code and, across the county line, its own school district. Five luxury areas, one map.
Census ZIP area 30004 overlaps the cities of Milton, Alpharetta and Roswell plus unincorporated land, and spans Fulton, Forsyth and Cherokee counties; by land area it is about 61% Milton and 7% Alpharetta.

Lot 01City of Alpharetta · the walkable core
The historic downtown and City Center on one side of GA 400, Avalon’s shops and residences on the other, and the streets you can walk from.
Trade-off: Smaller lots and closer neighbors, in exchange for walking to dinner and events.
Read the Downtown & Avalon guide
Lot 02City of Alpharetta · lake and club district
Northeast Alpharetta along Windward Parkway: Lake Windward, club golf, office campuses on GA 400, and the county line a few minutes away.
Trade-off: City services and a short GA 400 commute, but the Forsyth line runs close: check every parcel’s county.
Read the Windward guide
Lot 03City of Milton · acreage and horse country
Its own city since 2006, mostly zoned agricultural with one-acre minimum lots: pasture, barns, golf communities and big estates.
Trade-off: Space, privacy and lower city millage, but longer drives and septic systems to inspect.
Read the Milton guide
Lot 04City of Johns Creek · river and club country
Its own city since 2006, east of Alpharetta along the Chattahoochee, with Atlanta Athletic Club and the gated Country Club of the South.
Trade-off: The lowest of the three city levies and the river at hand, but an Alpharetta address that hides the city name.
Read the Johns Creek guide
Lot 05Unincorporated Forsyth County
North of the Fulton line, thousands of Forsyth County addresses still read “Alpharetta”: no city levy, Forsyth taxes and Forsyth County Schools.
Trade-off: The lowest combined millage of the four, but a different county, a different school district and fewer city services.

Johns Creek, on the east side
Club fairways, the Chattahoochee and an Alpharetta mailing address. The tax bill still says Johns Creek.

Each one comes from the statute, the government or the survey that sets it, with the date we checked.

40%
Georgia law

Deadline
In Georgia you may apply for a homestead exemption any time after the home becomes your primary residence, up to April 1 of the first year you want it. Not applying counts as waiving the exemption.

Exemptions by government04
$1 / $1,000
At closing
Georgia's real estate transfer tax is $1 for the first $1,000 of the sale price plus 10 cents for each additional $100 or part of $100, which works out to $1 per $1,000. It must be paid before the deed can be recorded (O.C.G.A. 48-6-1 to 48-6-10).

1 acre
Milton zoning
Milton covers more than 39 square miles. The City says about 85% of it is agriculturally zoned, so residential lots there must be at least 1 acre.

City of Milton: an estimated 3,410 owner-occupied homes (30.9%) were valued at $1,000,000 or more: 2,261 at $1M-$1.49M, 676 at $1.5M-$1.99M and 473 at $2M or more (ACS 2020-2024).

All three citiesTax + closing estimator
Enter a value and pick where the home sits. The estimate uses each government’s adopted tax-year-2025 millage (the latest year final for all four) and the homestead exemptions you can file for, then adds Georgia’s two closing taxes.
Alpharetta’s $45,000 city homestead exemption does not apply to the city bond levy (City of Alpharetta).
Milton’s $15,000 basic exemption applies to city operations (City of Milton).
We apply Johns Creek’s $15,000 basic exemption to the operating levy only, which may slightly overstate the bill.
Forsyth’s $8,000 exemption applies to county operations and fire; schools get $2,000 (Forsyth County Board of Assessors).
| Where the home sits | Yearly tax, no homestead | With homestead exemptions |
|---|---|---|
| City of Alpharetta | $19,121 | $18,595 |
| City of Milton | $18,373 | $18,010 |
| City of Johns Creek | $17,917 | $17,564 |
| South Forsyth | $14,713 | $14,619 |

No. Milton has been its own city since 2006, with its own council, tax rate and zoning. Many Milton homes still have Alpharetta mailing addresses because the ZIP codes cross the city line.

Not necessarily. Fulton County Schools’ address records use “Alpharetta” as the mailing city for ZIPs 30004, 30005, 30009 and 30022, including addresses in Milton, Johns Creek and Roswell. Check the parcel’s tax district.
