Georgia's HB 581 created a floating homestead exemption to limit assessed-value growth, but it is not a blanket tax freeze. Coverage depends on your homestead filing status and whether your county, city, or school district opted out of the law.
# Does Georgia's New HB 581 Property Tax Cap Apply to Your Home?
Georgia homeowners keep hearing about a "new property tax cap," but HB 581 is not a one-size-fits-all freeze. It created a statewide floating homestead exemption that can limit how much your taxable assessed value rises, but only if your home qualifies and the specific taxing authority on your bill did not opt out.
HB 581 probably applies to your home if four things are true:
If any one of those breaks, the answer may be only partly yes—or no. HB 581 applies by taxing authority, so one part of your bill can be protected while another part is not.

HB 581 created a statewide floating homestead exemption. The law says the exemption equals the amount by which your current year assessed value exceeds your previous adjusted base-year assessed value. In plain language, it is meant to limit inflation-driven assessment growth on a qualifying homestead. It is not a promise that your entire tax bill will stay flat.
For homeowners who first qualified in tax year 2025, the base year was the home's 2024 assessed value. Starting with the 2026 digest year, the Georgia Department of Revenue began publishing the annual inflation index used in the calculation, and the published index for 2026 is 2.7%.
To receive Georgia homestead benefits for the current tax year, you generally must have owned the home on January 1 and filed with your county tax officials by April 1. Georgia now also allows current-year homestead applications through the end of the 45-day appeal window after your assessment notice.
The law is for a homestead, meaning your primary residence—not a rental, vacation home, or other investment property. And if another base-year value homestead exemption already applies to the same taxing jurisdiction, the county is supposed to use only the more beneficial one rather than stack both.
First, it may not apply to every line on your bill. HB 581 lets a county, municipality, or school district opt out, so your coverage can be mixed depending on where you live and which authorities tax your property.
Second, the protection does not transfer to a new owner. If you bought the home recently, you do not inherit the prior owner's base-year protection. Your own eligibility and base year have to be established under the law.
Third, major additions or improvements can still raise the protected value. The statute specifically adds in the value of "substantial property change," so things like new square footage or major improvements can increase assessed value above the normal inflation adjustment.
Fourth, this is not a cap on everything. The law addresses assessed-value growth on a covered homestead, but millage rate changes can still affect your bill, and the statute excludes taxes levied to pay bonded indebtedness from this exemption framework.
Start with your homestead status. If you never filed homestead on this property, HB 581 is usually not your first issue. You need to confirm whether your county has you coded as a primary-residence homeowner.
Next, break your bill into its parts: county, school district, and city if you live inside city limits. HB 581 can apply differently to each one.
Then look for an opt-out notice. Georgia now requires a homestead property tax bill to identify any taxing authority that opted out of HB 581-related relief and to include a phone number for that authority when no generally applicable base-year exemption is in place.
Finally, compare what changed. If your taxable value rose far more than inflation and you did not buy recently, did not lose homestead, and did not make major improvements, that is a good reason to look more closely at both your exemption status and your assessment.
Assume your covered homestead had an assessed value of $200,000 and there were no major improvements. If the 2026 inflation index is 2.7%, the adjusted base-year value would rise modestly, not jump to match a much larger market increase. So if the county assessed the home at $215,000, part of that increase could be offset by the HB 581 exemption for any taxing authority that did not opt out. That does not guarantee your total bill stays flat, but it can reduce the taxable value used for that part of the bill.
The real question is not just, "Did Georgia pass a new property tax cap?" It is, "Does my primary residence have a valid homestead exemption, and did each taxing authority on my bill keep or opt out of HB 581 relief?" Once you answer those two questions, the picture gets much clearer. If your bill still looks too high after that, the next step is to separate an exemption issue from an assessment issue before deciding what to do next.
