The Georgia property tax cap limits how much your home’s assessed value can climb each year to the prior year’s inflation rate, keeping a hot real estate market from driving your tax bill up faster than the cost of living. The cap took effect on January 1, 2025 under O.C.G.A. § 48-5-44.2 and applies automatically to any qualifying homestead, unless your county, city, or school district opted out during a one-time window that closed in early 2025.1Justia. Georgia Code 48-5-44.2 – Base Year Homestead Exemption
How the Cap Limits Your Assessed Value
The cap does not freeze your home’s value. It caps the annual increase in your assessed value at the prior year’s inflation rate, as determined by the Georgia Revenue Commissioner using the Consumer Price Index or a similar federal measure.1Justia. Georgia Code 48-5-44.2 – Base Year Homestead Exemption If inflation ran 2.8 percent last year, your assessed value can rise by no more than 2.8 percent this year, even if comparable homes down the street sold for 15 percent more.
The math runs off an “adjusted base year” value. For homeowners who first received the exemption in tax year 2025, the base year is your final 2024 assessed value. If you apply later, your base year is the assessed value from the year immediately before you first receive the exemption. Each year after that, the adjusted base grows by no more than the inflation rate applied to the previous year’s adjusted base.
Because the 2025 adjusted base equals the 2024 base, homeowners already on the rolls in 2024 effectively saw no taxable-value increase from 2024 to 2025. That built-in first-year freeze delivered an immediate benefit.
One thing the cap does not hide: physical additions. Value added by major renovations or new construction gets tacked on separately, so a new addition still shows up on the tax rolls.
Who Qualifies
The cap rides on the homestead exemption, so only homestead property qualifies. Under O.C.G.A. § 48-5-40, a homestead is real property you own and occupy as your legal residence on January 1 of the tax year.2Justia. Georgia Code 48-5-40 – Definitions You have to actually live there. Second homes, vacation properties, rental units, and commercial or industrial properties are out.
Only one homestead exemption is allowed per immediate family group.2Justia. Georgia Code 48-5-40 – Definitions If you own two houses, you pick one. And this is a continuing obligation. Move out, rent the place, and you lose the exemption; the cap resets when you or a new owner claims it again.
Property held in a trust can still qualify, as long as a natural person actually lives in the home as their primary residence. You will likely need to provide the trust document along with an affidavit when you apply.3Georgia.gov. Apply for a Homestead Exemption Trust paperwork requirements vary by county, so ask your local tax office what they need.
How to Claim the Cap
You do not apply for the cap directly. You apply for the homestead exemption, and the cap comes with it. Filing is done with your county tax commissioner’s office, though in some counties the tax assessor handles it instead.4Georgia Department of Revenue. Property Tax Homestead Exemptions
The right form is the LGS-Homestead (Application for Homestead Exemption), available from the Georgia Department of Revenue or your county tax office.5Georgia Department of Revenue. Real and Personal Property Forms and Applications Do not confuse it with Form PT-50R, which is for returning real property and improvements, not for claiming the exemption.
The traditional filing deadline is April 1. Georgia now allows applications after that date, up through the end of your 45-day window to appeal the annual notice of assessment, but filing by April 1 is still the safest route because it locks in the exemption for the current tax year without complications.4Georgia Department of Revenue. Property Tax Homestead Exemptions You must have owned the property on January 1 to qualify for that year.
Bring your parcel identification number, a copy of your recorded deed, and a Georgia driver’s license or state ID showing the property address. Your county may ask for more. Once approved, most homeowners do not need to reapply each year as long as they keep living in the home, though some counties require periodic re-verification.
Where the Cap May Not Apply
The statewide cap applies by default, but every county, municipality, consolidated government, and school district got a one-time chance to opt out. To do so, the governing authority had to adopt a resolution by March 1, 2025 after holding at least three advertised public hearings.1Justia. Georgia Code 48-5-44.2 – Base Year Homestead Exemption
Where a taxing authority opted out, your assessed value for that authority’s portion of your bill is not capped. You could be capped for county taxes but uncapped for school taxes, or the other way around, depending on which entities in your area went through the opt-out. Your county tax commissioner can tell you exactly which taxing authorities in your area participate.
Local Floating Exemptions Still Count
Long before House Bill 581, many Georgia counties and cities offered their own floating homestead exemptions through local legislation. Those work on a similar principle, freezing or limiting taxable value to a base year. The statewide cap does not replace them. If your county or city had a local floating exemption before 2025, it stays in place, and you benefit from whichever arrangement produces the lower taxable value. Local versions vary in how they set the base year and which portions of the bill they cover; § 48-5-44.2 sets a uniform floor tied to inflation for jurisdictions that never had one.
Fixing an Inflated Base Year Through Appeal
The cap protects you from runaway increases, but it does not stop your county from overvaluing your home in the first place. Getting the base year right matters more now than it used to, because that value anchors every future year’s cap calculation. An inflated base compounds forward.
Under O.C.G.A. § 48-5-311, you must file an appeal within 45 days of the date your assessment notice was mailed. A written objection identifying your property and its parcel number counts as a valid appeal. The county board of tax assessors reviews first; if they disagree, the case goes to the county board of equalization for a hearing where you can present evidence such as recent comparable sales, an independent appraisal, or documentation of property defects.6FindLaw.

What Happens When You Sell
Assessment caps come with a side effect that catches sellers off guard. The longer you stay, the wider the gap between your capped taxable value and the home’s current market value. That gap is a tax benefit you lose the moment you sell. Buy a new home, apply for a fresh homestead exemption, and your base year resets to the current assessed value.1Justia. Georgia Code 48-5-44.2 – Base Year Homestead Exemption
For someone who has been capped for a decade in a rapidly appreciating neighborhood, selling can mean a steep jump in property taxes at the new address. Empty nesters trading down to a smaller house may find that the move raises their tax bill instead of lowering it. Factor the potential increase into your moving budget before you list.
