How Much Can Property Taxes Increase in Georgia? Complete 2026 Guide
Updated July 2026
Quick Answer
Georgia is in the middle of the biggest property tax change in a generation. A floating homestead exemption (HB 581) has capped taxable value growth at the inflation rate since 2025 in participating jurisdictions, and the HOME Act (SB 33), signed May 11, 2026, makes that inflation cap mandatory statewide starting in 2027, with no local opt-outs.
Until then, protection is a patchwork: many metro Atlanta counties and most school districts opted out of HB 581, so a homestead in Fulton or Gwinnett can still see its taxable value rise with the market through 2026. Non-homestead property has no cap at all.
Most homeowners never challenge their assessment, usually because nobody tells them they can or shows them how. That gap is the whole reason AppealDesk exists: see what your county has your home on record at, free, and if the number looks wrong we build the case for $49.
How Much Can Property Taxes Increase Per Year in Georgia?
The honest answer depends on which year, which county, and whether the property is your homestead. Before 2025, Georgia had no statewide limit: assessments tracked the market, and homeowners in fast-appreciating metro Atlanta neighborhoods saw taxable values jump 20% to 40% in a single reassessment. That era produced the voter backlash that created today's reforms.
Since 2025, if your county, city, and school district participate in HB 581's floating homestead exemption, the taxable value of your primary residence can grow no faster than inflation, regardless of what the market does. The catch is the word "participate": local governments were allowed to opt out by early 2025, and roughly two-thirds of school systems and a third of counties did, including most of metro Atlanta's biggest taxing authorities. In an opted-out jurisdiction, nothing caps your assessment through 2026.
That patchwork has an expiration date. The HOME Act (Senate Bill 33), signed by Governor Kemp on May 11, 2026, makes the inflation cap mandatory for every county, city, and school district starting with the 2027 tax year. It also requires voter approval before a local government adopts a budget projected to grow property tax revenue faster than the greater of 3% or inflation, and it lets counties adopt a 1% local homestead-relief sales tax beginning in 2028.
Caps and rate limits only control how fast your bill can grow. Nothing in them checks whether the number underneath is right. Assessors in Georgia set values with mass-appraisal models that price thousands of homes at once, and nobody reviews yours unless you challenge it.

How Georgia Calculates Your Bill
Georgia assesses property at 40% of fair market value, then applies your local millage rate to that assessed value after exemptions. A $400,000 home carries a $160,000 assessed value; at a combined 25 mills, that is $4,000 before exemptions. Counties assess annually with values set as of January 1, and the state Revenue Commissioner reviews each county's digest, which is why Georgia assessments track the market faster than states on multi-year cycles.
The millage side has its own restraint: Georgia's rollback rule requires taxing authorities to advertise a "property tax increase" and hold three public hearings whenever they keep a millage rate that collects more revenue from reassessment growth instead of rolling the rate back. It slows quiet increases; it does not stop them.
What Is Georgia's Average Property Tax Rate in 2026?
Because Georgia taxes 40% of market value, the meaningful number is your effective rate on market value, which for most Georgia homeowners lands around 1% or a little under, varying by county and school district millage. A useful rule of thumb: every 25 mills of combined millage equals about 1% of your home's market value per year. Metro Atlanta school districts push many bills above that; rural counties with lower millage sit below it.
If your bill jumped in 2026, Fulton County is a live example of why the transition period matters: its school district opted out of HB 581, so homestead values there still floated with the market this year. Under the HOME Act, 2026 is the last year that gap exists.
Do Property Taxes Go Up Every Year in Georgia?
Usually, yes, through some combination of reassessment and millage. Annual assessment means your value moves with the market every January 1, and even where HB 581 caps homestead growth at inflation, inflation is not zero. From 2027 the pattern becomes more predictable statewide: homestead taxable values grow at most at the inflation rate, the way Michigan's and Florida's caps already work.
What no cap ever does, in Georgia or anywhere, is check whether your starting value is right. The 2027 cap will freeze in whatever assessment you carry into it, which makes the next two assessment cycles the ones to scrutinize: an inflated 2026 value becomes the base your capped growth compounds from.

Georgia: Inflation cap from 2027. That is a different kind of limit from the bars above, which cap the assessment itself.
The HOME Act makes an inflation-linked homestead cap mandatory statewide from the 2027 tax year.
A cap limits how fast the number grows. It does not check whether the number was right to begin with.
What you can do about it
Appealing Your Georgia Assessment
Every Georgia owner receives an annual assessment notice and has 45 days from the notice date to appeal, first to the county Board of Assessors and then to the Board of Equalization at no filing cost. Comparable sales are the standard evidence, and Georgia adds a quirk worth knowing: a successful appeal generally locks the resulting value for the following two years, and a sale price can cap the next year's value under state law. With the HOME Act about to freeze bases, a 2026 appeal has more long-term leverage than usual.
A real AppealDesk order, Fulton County
In July 2026, a homeowner in Fulton County ran the check. The county had their home on record at $1,154,400, while recorded sales of comparable homes supported about $855,792: an over-assessment of $298,608, worth roughly $7,465 per year if corrected. Their packet laid out the comparable sales, the forms, and the filing steps. Nobody at the county was ever going to run that check for them.
Growth limits only help if the number they grow from is fair. If your assessment jumped after a purchase, new construction, or a revaluation, that new number is the one nobody has reviewed. Checking it is free and takes about a minute.

Frequently Asked Questions
Does Georgia have a property tax cap now or not?
Both, depending on where you stand in the transition. HB 581's inflation cap has protected homesteads since 2025 in jurisdictions that did not opt out. The HOME Act (SB 33, signed May 2026) makes the cap universal for homesteads starting in 2027, ending the opt-outs. Non-homestead property (rentals, commercial, second homes) remains uncapped.
My county opted out of HB 581. What does the HOME Act change for me?
Starting with the 2027 tax year, the opt-out no longer exists: your homestead's taxable value growth is capped at inflation no matter what your county or school district decided in 2025. Your 2026 assessment still floats with the market, which is exactly why it is worth verifying before it becomes your capped base.
Why did my Fulton County taxes increase in 2026?
Most likely reassessment: Fulton's school district opted out of HB 581, so homestead taxable values there still tracked the market in 2025 and 2026. Millage decisions and the loss of any expiring local exemption can add to it. From 2027 the HOME Act caps homestead growth in Fulton like everywhere else.
Does the cap apply to my rental property or second home?
No. Both HB 581 and the HOME Act cover homestead property only, your primary residence with a homestead exemption on file. Investment and commercial property assessments remain uncapped and track the market annually.
How do I know if my assessment is too high?
Compare the fair market value on your assessment notice against what similar homes near you actually sold for around January 1 of the tax year. If recorded sales of comparable homes are consistently below your noticed value, you have the beginnings of an appeal, and 45 days from the notice date to file it.
The Bottom Line
Georgia is moving from one of the least protective states to a capped one: patchwork inflation caps now, universal homestead caps in 2027 under the HOME Act. The transition makes this the moment to make sure the county's number for your home is right, because the cap that starts in 2027 will grow from whatever base you carry into it. Check the number, and challenge it within your 45-day window if the sales around you say it is wrong.
