Key Takeaways
- Your notice sets a value, not a bill: Each year the Fulton County Board of Assessors sends every property a notice with its fair market value (Fulton County Board of Assessors). Georgia taxes 40% of that value.
- SB 33 makes the homestead cap mandatory: Georgia's 2026 law makes the statewide base-year homestead exemption "mandatory for all political subdivisions" (Georgia SB 33). The taxable base of the house you live in can then grow no faster than the prior year's inflation rate, plus improvements.
- The cap limits value, not your bill: Millage rates can still raise the bill, and rentals and second houses get no homestead cap at all.
- You have 45 days to appeal: The window runs from the date of your notice, and the deadline is printed on it.
- DeKalb appeals go to the DeKalb Board of Assessors: Part of Atlanta sits in DeKalb County, which runs its own notices and appeals.
- A reassessment is information: It can prompt an appeal, a homestead application, or a fresh look at what your house could sell for. None of those choices has to be made in a hurry.
A Fulton County property tax reassessment arrives as your Annual Notice of Assessment, and the number on it can look alarming. This guide explains what that notice means and how Georgia's SB 33 homestead cap now limits the taxable value of the house you live in. It also shows how to use your 45-day appeal window. It also covers DeKalb County, the 2026 tax bills, and how to weigh keeping, appealing, or selling.
Every rule here comes from the law or the county office that applies it, with links so you can check each one. Propcash is a direct cash homebuyer, not a tax advisor, so confirm anything about your own bill with the Board of Assessors or a Georgia tax professional.

Let's chatHow a Fulton County Property Tax Reassessment Works
A Fulton County property tax reassessment is the yearly notice that sets your property's fair market value for tax purposes. The county says "Each year the Fulton County Board of Assessors issues notices of assessment to every property in Fulton County, pursuant to state law." It adds that "The notice includes an assessment of each property's fair market value" (Fulton County Board of Assessors).
Georgia then taxes a share of that value. The county's homestead guide says the assessed value "in Georgia is, by statute, 40% of the fair market value." That assessed value "is the value used by the Tax Commissioner's Office to calculate tax bills" (Fulton County 2025 Homestead Exemption Guide). Exemptions come off the assessed value, and each taxing body's millage rate applies to what is left.
From the number on your notice to a taxable value
The example below is illustrative only. It uses a made-up $300,000 fair market value and the Fulton County basic homestead exemption amounts from the county's guide. It stops before millage, because rates differ by city and school district and are set each year.
| Step | Illustrative Figure | Where the Rule Comes From |
|---|---|---|
| Fair market value on the notice | $300,000 (example) | Fulton County Board of Assessors notice |
| Assessed value (40%) | $120,000 | Georgia statute, per the Fulton County 2025 guide |
| Less basic homestead exemption, county levy | $120,000 minus $30,000 = $90,000 | Fulton County 2025 Homestead Exemption Guide |
| Less basic homestead exemption, school levy | $120,000 minus $2,000 = $118,000 | Fulton County 2025 Homestead Exemption Guide |
| Rental or second house (no homestead) | $120,000 for every levy | Homestead exemptions apply only to the owner's residence |
Floating exemptions, covered next, can lower the taxable figure further for a homestead. That is why two identical houses on the same street can carry very different bills.
How SB 33 Limits a Homestead's Taxable Value
SB 33 requires every local government in Georgia to apply the statewide base-year homestead exemption, so Fulton and DeKalb can no longer opt out of it. Its title says the Act works "to make the state-wide base year homestead exemption mandatory for all political subdivisions" (Georgia SB 33). Governor Kemp signed it on May 11, 2026 (Office of the Governor), and Section 6-1 says it "shall become effective upon its approval by the Governor."
What the cap does
The cap works through an "adjusted base year assessed value." Under SB 33, the yearly increase in that value "shall not exceed the total of the previous adjusted base year assessed value of the homestead multiplied by the inflation rate for the prior year." Additions or improvements to the house, which the law calls a "substantial property change," can still raise it. In plain terms, rising sales on your street should not push the taxable base of your homestead up faster than inflation.
SB 33 also amends O.C.G.A. 48-5-44.2 so that an owner who had a homestead exemption in 2024 and stayed eligible "shall be automatically allowed the exemption" without a new application. Section 5-3 adds another protection for a homestead exemption applied by mistake, with no fraud by you. In that case the tax office is "prohibited from retroactively assessing the taxpayer the difference."
What the cap does not do
The cap limits value, not your bill. Fulton County's guide says "Your actual tax bill may increase by 3% or more depending on the millage rate set by the various taxing jurisdictions" (Fulton County 2025 Homestead Exemption Guide). The cap also covers only a homestead, so a rental or second house you own gets no protection from it. Ask the Board of Assessors how and when the cap shows on your own notice.
Under SB 33, a new applicant's base year is the assessed value "from the taxable year immediately preceding the taxable year in which the exemption under this Code section is first granted." If you sell and buy elsewhere in Georgia, your next house starts its own base year, so compare the full tax picture before you move.
Homestead Exemptions in Fulton County and Atlanta
Fulton County and the City of Atlanta offer homestead exemptions well above the $2,000 state minimum, and you must apply to receive them. The Georgia Department of Revenue says you qualify if the house "was owned by the homeowner and was their legal residence as of January 1 of the taxable year." It adds that owners "may apply up to the end of their 45-day window to appeal their notice of assessment" (Georgia Department of Revenue).
| Exemption | Who Qualifies | What It Does |
|---|---|---|
| State standard homestead (O.C.G.A. 48-5-44) | Any Georgia owner who occupies the house as a primary residence | $2,000 off the 40% assessed value for county and school taxes (Georgia Department of Revenue) |
| Fulton County and City of Atlanta basic homestead | Owners who occupy the house on January 1; no age or income limit | $30,000 off the county assessed value and $2,000 off school; City of Atlanta residents also get $30,000 off city operations, the city park fund, and city school |
| Fulton County CPI homestead freeze | Owners receiving a Fulton homestead exemption | Limits the yearly rise in the county base value to the lesser of CPI or 3% |
| Fulton County basic senior exemption | Age 65 or older on January 1; no income requirement | $50,000 off, county operations only |
| Statewide base-year exemption (mandatory under SB 33) | Homestead owners statewide | Limits base-year value growth to the prior year's inflation rate; Fulton applies whichever floating exemption helps you more |
Rows two through four come from the Fulton County 2025 Homestead Exemption Guide, which says that when a local and the state floating exemption both apply, "the taxpayer will receive whichever of the two exemptions is more beneficial." The guide lists more exemptions for seniors, disabled veterans, and surviving spouses, and its deadline to apply is April 1. Amounts can change, so confirm them on the Fulton County homestead page.
How Do You Appeal a Fulton County Assessment?
You appeal a Fulton County assessment by filing with the Board of Assessors within 45 days of the date on your notice. The county says owners "have the right to file an appeal within 45 days of the date of the Notice of Assessment." If you miss the date printed on your notice, "your right to file an appeal will be lost" (Fulton County Board of Assessors).
The appeal is about value, not the bill. Fulton says you can appeal only the assessed value, "not your property's estimated tax." You can file online, in person at a Board of Assessors office, or by mail. The 45-day rule is statewide. The Department of Revenue says an owner "may do so within 45 days of the date the Assessment Notice was mailed," and the appeal "is filed with the County Board of Tax Assessors" (Georgia Department of Revenue, Filing a Property Tax Appeal).
The three routes you choose when you file
- Board of Equalization. The Board of Assessors reviews your appeal first and may send an amended notice, which you can appeal "within 30 days." Otherwise the appeal goes to the Board of Equalization for a hearing, and the next step after that is Superior Court (Georgia Department of Revenue).
- Arbitration. A value-only route. You submit a certified appraisal, and the side whose value lands farther from the arbitrator's finding pays the arbitrator's fees and costs (Georgia Department of Revenue).
- Hearing officer. Open only for non-homestead real property valued above $500,000, on value or uniformity (Georgia Department of Revenue).
Fulton says "The appeals process can take several months," and "you may receive a temporary tax bill while your appeal is pending. You must pay that temporary bill or risk receiving additional penalties and fees." An appeal never pauses the due date.
Bring evidence of value: recent sales of similar houses near you, photos of condition problems, and repair estimates. If you have not filed for a homestead exemption yet, the Department of Revenue allows that application up to the end of the same 45-day window.
If Your Atlanta House Is in DeKalb County
If your Atlanta house sits in DeKalb County, the DeKalb Board of Assessors, not the Tax Commissioner, handles your notice and your appeal. The DeKalb County Property Appraisal Department lists "Appeals Processing" among its jobs and offers an online appeal and a printable form. It says "All real estate appraised at 100% fair market value, assessed at 40%."
DeKalb mailed its 2025 assessment notices on June 3, 2025, according to the same page. It also says that under O.C.G.A. 48-5-311(e)(3)(B), "the DeKalb Board of Assessors is granted an additional 180 days to review and respond to 2025 appeals," because appeals passed 3% of all parcels. The statewide 45-day window and the same three appeal routes apply in DeKalb. DeKalb is also on the Department of Revenue's list of counties with a base-year valuation freeze.
The 2026 Fulton County Tax Bills
Fulton County's 2026 tax bills went out on August 15, 2026 as temporary bills. The county said they were "based on valuations in the preliminary 2026 Tax Digest and each taxing jurisdiction's 2025 millage rate," as authorized by the Superior Court of Fulton County (Fulton County, August 14, 2026). Once millage rates are set, "A refund or revised tax bill will be issued only as needed."
The same release set the due dates: "City of Atlanta property taxes are due by September 30, 2026. Fulton County taxes, and those from all other jurisdictions, are due by October 15, 2026." Interest starts the day after the due date. A 5% penalty is added on the 120th day and again every 120 days, "up to a maximum of 20%." The Tax Commissioner accepts partial payments.
If a bill is already past due, the clock that matters is the county tax sale, not the assessment. Our guide to Georgia property tax sales covers how that process works and the options before a sale date.
What the Atlanta Market Says About Your Value
Atlanta's recent sales data is the best check on whether the value on your notice is fair. Redfin reports a median sale price of about $424,898 in the three months ending September 2026, up 10.8% from about $383,500 a year earlier (Redfin, September 2026). Zillow's typical value index for the city reads about $380,331, down about 1.9% year over year (Zillow ZHVI, September 2026).
| Metric | Value | Source |
|---|---|---|
| Median sale price | About $424,898, up 10.8% year over year | Redfin, September 2026 |
| Median days on market | About 63 days, down from 69 a year earlier | Redfin, September 2026 |
| Houses sold | 1,490 in the three months ending September 2026, down from 1,747 | Redfin, September 2026 |
| Average sale-to-list ratio | 97.4% | Redfin, September 2026 |
| Typical house value (ZHVI) | About $380,331, down about 1.9% year over year | Zillow ZHVI, September 2026 |
Redfin and Zillow measure different things, so their figures are reported separately and never blended. Redfin tracks the middle of actual sales in the period, while Zillow's index estimates the typical value of all houses in the city. Neither one is your house. For an appeal, the sales that count are recent sales of houses like yours, close to yours.
Keep, Appeal, or Sell After a Reassessment
Most owners who get a higher reassessment should first make sure every exemption is in place and appeal any value that looks wrong. Selling only makes sense when your numbers and your plans point that way. Here is how the common situations sort out:
- You live in the house and the value looks too high. Confirm your homestead exemption, then appeal within 45 days with comparable sales.
- You live in the house and the value looks right. The SB 33 cap and Fulton's floating exemptions limit how fast your taxable base grows, so the higher number may cost less than it looks. Check your bill against last year's.
- The house is a rental or a second house. No homestead cap applies, so its taxes can track the sales around it. Our guide for tired landlords selling an Atlanta rental covers that case.
- The bill is not the real problem. If the house needs repairs you would rather not fund, or your life is moving elsewhere, the reassessment is a good moment to learn what the house could sell for.
The equity side of a higher value
A higher fair market value is also a sign of equity. Here is an illustrative example, not an offer or an appraisal. Suppose you bought an Atlanta house in 2012 for $150,000, and recent sales on your street suggest it could sell near $360,000. That is a gain of about $210,000 over your purchase price, before closing costs.
Federal law can shelter much of that. The tax code says "Gross income shall not include gain from the sale or exchange of property" in certain cases. You must have owned and used the house as your principal residence "for periods aggregating 2 years or more" in the 5 years before the sale (26 U.S.C. 121). The excluded gain "shall not exceed $250,000," or $500,000 for a married couple filing jointly who meet the rules. Propcash is not a tax advisor, so confirm your own numbers with a tax professional.
Long-time owners in changing intown neighborhoods face this choice often. Our guide to selling a house in a gentrifying Atlanta neighborhood covers the stay-or-sell decision in more depth.
How a Direct Cash Offer Works
A direct cash offer means one buyer, one written number, and a closing date you choose. Propcash is a direct cash homebuyer. Tell us about your house, and we'll make you a cash offer based on local market data and show you how we got to our number. There are no fees, no commissions, and no obligation to accept.
You do not need to wait for an appeal to finish before you sell, and our offers do not expire, so you can decide on your own schedule. You can sell as-is, with no repairs, no cleanout, and no showings. Closing can happen in as few as 7 days after the contract is signed, or on a later date that fits your plans. If listing with an agent would clearly serve you better, we'll tell you and point you to a local agent who fits. We may receive compensation from agents we refer. See how it works on our Atlanta sell house fast page, or get a cash offer when you are ready.
The Bottom Line
A Fulton County reassessment sets the value your taxes start from, and for a homestead, SB 33 now limits how fast that taxable base can grow. Check your exemptions, appeal within 45 days if the value looks wrong, and pay any temporary bill on time. If the house no longer fits your plans, the reassessment is a reasonable moment to see what it could sell for, with no deadline on the decision.

Let's chatFrequently Asked Questions
How much can my Fulton County property tax assessment increase in one year?
The fair market value on your notice has no fixed yearly limit, because it follows sales of similar houses. For a homestead, SB 33 (2026) makes the statewide base-year exemption mandatory (Georgia SB 33). The taxable base can then rise by no more than the prior year's inflation rate, plus improvements. Fulton's own CPI freeze limits county base value growth to the lesser of CPI or 3%, and you receive whichever floating exemption helps you more. A rental or second house gets no homestead cap, so its taxable value can rise with the market.
How long do I have to appeal my Fulton County property tax assessment?
You have 45 days from the date of your Notice of Assessment to file an appeal with the Fulton County Board of Assessors, and the deadline is printed on the notice. You can file online, in person, or by mail, and you choose the Board of Equalization, arbitration, or, for qualifying non-homestead property, a hearing officer. The appeal covers the value on the notice, not the estimated tax.
Does the Georgia homestead exemption protect me from a reassessment increase?
Partly, and more than the $2,000 state minimum suggests. Fulton County's basic homestead exemption takes $30,000 off the county assessed value and $2,000 off school. City of Atlanta residents get another $30,000 off city operations, the city park fund, and city school (Fulton County 2025 Homestead Exemption Guide). SB 33 also limits how fast a homestead's taxable base can grow. Your bill can still rise if millage rates go up, and you must apply to receive these exemptions.
What happens if I miss the 45-day appeal window in Fulton County?
Fulton County says that if you do not file by the deadline printed on your notice, your right to file an appeal will be lost. The value on that notice then stands for that tax year. The Board of Assessors sends a new notice each year, so you can review and appeal the next one. If you have not yet applied for a homestead exemption, do that by the county's deadline so next year's value carries it.
Is DeKalb County's reassessment process the same as Fulton's?
The rules are the same statewide, but DeKalb runs its own process. Notices and appeals in DeKalb go to the DeKalb Board of Assessors through the Property Appraisal Department, not the Tax Commissioner. DeKalb appraises at 100% of fair market value and assesses at 40%, and the 45-day window and the three appeal routes apply there too. SB 33's mandatory base-year homestead exemption covers DeKalb homesteads as well.
Can I sell my Fulton County house before my property tax appeal is resolved?
Yes. Nothing requires you to wait for an appeal to finish before you sell. Fulton says appeals can take several months and that you must pay any temporary bill issued while the appeal is pending. How the year's taxes are divided between you and the buyer is set in the purchase contract, so ask your closing attorney how a pending appeal will be handled.
Will my Fulton County property taxes keep going up every year?
Not necessarily, and it depends on whether the house is your homestead. For a homestead, SB 33 and Fulton's floating exemptions limit how fast the taxable base grows, but Fulton County notes the bill may still rise 3% or more depending on millage rates. For a rental or second house, the taxable value can follow the market each year. The 2026 Fulton bills were temporary bills using 2025 millage rates, so a refund or revised bill may follow.
