If you are comparing Fulton, Cobb, and Gwinnett counties before buying, the Georgia homestead exemption should factor heavily into your decision. Property tax bills can vary by thousands of dollars a year depending on which county you choose, and the exemptions available to you can cut that bill significantly. This guide breaks down how each county taxes homeowners and how to claim every exemption you qualify for.

Fulton, Cobb, and Gwinnett each set their own millage rates and offer different homestead and senior exemption programs. Filing for the Georgia homestead exemption by the April 1 deadline is the single biggest step most homeowners skip, and it can lower your taxable value by thousands of dollars every year you own the home.
How Property Taxes Compare Across the Three Counties
Each county calculates property taxes using its own millage rate, applied to your home’s assessed value. Fulton County tends to carry higher overall rates in its urban core, while Cobb and Gwinnett often land lower, though city-level add-ons inside each county change the math.
Fulton County
Rates in Fulton County vary widely by city. Homes inside Atlanta city limits pay both county and municipal millage. Homes in unincorporated Fulton or smaller cities like Alpharetta and Sandy Springs pay a different blend. Fulton also caps annual assessment increases for homestead properties, and that cap helps long-term owners avoid sudden spikes.
Cobb County
Cobb County generally offers some of the more competitive rates in the metro area. As a result, many buyers moving from Fulton find their tax bill drops, even on a similarly priced home. On top of the state-level program, Cobb also offers its own homestead exemption, and that stacks additional savings for owner-occupants.
Gwinnett County
Gwinnett’s rates sit in a similar range to Cobb’s. The county has also invested heavily in its own local exemption programs for seniors and disabled homeowners. Additionally, Gwinnett freezes assessed value for qualifying seniors, and that can matter a great deal over a long hold period.
What the Georgia Homestead Exemption Actually Does
This exemption reduces the taxable value of your primary residence before the county calculates your bill. To qualify, you must own and occupy the home as your primary residence as of January 1. You must also file your application with the county tax assessor by April 1. Consequently, missing that deadline means waiting a full year to claim the savings.
| County | Standard Homestead Exemption | Filing Deadline |
|---|---|---|
| Fulton | State + county assessment cap for homestead owners | April 1 |
| Cobb | State + additional county-level homestead exemption | April 1 |
| Gwinnett | State + local exemptions plus senior value freeze | April 1 |
Senior Exemptions: What Homeowners 62 and Older Should Know
Homeowners aged 62 and older often qualify for additional relief on top of the standard exemption. Fulton, Cobb, and Gwinnett each offer senior-specific programs that can exempt a larger portion of assessed value, and some tie eligibility to household income. For example, a senior household under a set income threshold may see school-tax portions of their bill reduced or eliminated entirely. Specifically, Gwinnett’s senior value freeze locks in your assessed value so future increases do not raise your bill, even as neighborhood values climb.

Is It Worth Comparing Counties Before You Buy?
Comparing county tax structures before you buy can save you real money over time, especially if you plan to use the Georgia homestead exemption and stay for years. However, taxes are only one factor. You should weigh them alongside commute, schools, and lifestyle fit. If you are still deciding where to land, our relocation checklist and Cobb County buyer guide both cover how location affects your total cost of ownership. For the most current millage rates and exemption forms, the Georgia Department of Revenue publishes official guidance for every county.
Frequently Asked Questions
Do I need to reapply for the homestead exemption every year?
No. Once approved, most Georgia counties automatically renew your homestead exemption each year as long as you continue to own and occupy the home as your primary residence.
Can I claim a homestead exemption in more than one county?
No. You may only claim a homestead exemption on one property, and it must be your legal primary residence as of January 1 of that tax year.
