Sandy Springs Property Tax Appeal: Is Your Assessment Fair?

Sandy Springs is one of the hardest cities in Georgia to mass-appraise. A high-rise condo on Roswell Road, a 1960s ranch in Riverside, a new build off Mount Vernon, a gated estate backing up to the Chattahoochee — the county has to value all of them with the same models, at the same time, every year. Sometimes those models land on your house. Sometimes they miss high, and you quietly overpay until someone checks.

We're a Georgia property-tax appeal service, and we'll be upfront about how we see it: most assessments are roughly fair, some are meaningfully wrong, and the only way to know which one you have is to look at the actual numbers. This page covers what we found when we did that for Sandy Springs, and how the appeal process works if your number is off.

Why Sandy Springs assessments miss

Mass appraisal leans on recent comparable sales. That works reasonably well in a subdivision of similar homes. It works badly at the top of the market, where Sandy Springs has a lot of inventory: custom homes, large riverfront lots, extensive renovations the county can't see, and properties with no true comparables within a mile. The higher and more unusual the home, the more room the model has to be wrong — and when it's wrong high, you pay for it every year.

There's also a quieter failure mode: unevenness. Two similar homes on the same street can carry very different assessments simply because the model treated them differently. Georgia law says that's appealable too — not just "my value is too high," but "my value is out of line with comparable properties." More on that below.

The 2026 deadline: July 31 for most notices

Fulton County mailed 2026 Annual Notices of Assessment in mid-June. From the date printed on your notice, you have 45 days to file an appeal — for most 2026 notices, that works out to July 31, 2026. The date on your own notice is the one that counts, so check it; there is no grace period and no late filing.

The 45-day window is the single most common way Sandy Springs homeowners lose money they could have kept. The notice arrives in June, it isn't a bill, it goes in a drawer — and the right to challenge that year's value quietly expires. We wrote a full breakdown of the timing here: the 45-day Fulton County appeal deadline.

What we found when we checked 1,460 Sandy Springs homes

We ran our valuation model across 1,460 higher-value Sandy Springs homes (median county valuation about $1.4M) and roughly 29% looked over-assessed, with median potential first-year savings around $4,500 for the homes with a real case. Most homes we check do NOT have a case — and we say so.

That 29% is worth sitting with for a second. It means roughly seven in ten of those homes were assessed fairly, or close enough that an appeal isn't worth anyone's time — including ours, since we only get paid when you save money. But it also means that in the higher-value neighborhoods of Sandy Springs, being over-assessed isn't a rare fluke. It's common enough that checking is just basic homeownership hygiene, the same way you'd glance at any other four- or five-figure bill before paying it.

The two grounds that win: Value and Uniformity

Georgia taxes property on 40% of its fair market value — the county sets the FMV, and the assessed value is 40% of that number. An appeal challenges the FMV, and under O.C.G.A. 48-5-311 the two grounds that carry almost every residential case are:

• Value. The county's FMV is simply higher than what your home would actually sell for, based on qualified comparable sales. This is the classic case: your value jumped, and the sales around you don't support the new number.
• Uniformity. Your home is assessed out of line with comparable properties — you're carrying a higher value per square foot than similar homes nearby, regardless of what the "right" market value is. For high-value Sandy Springs homes with few clean sale comps, uniformity is often the stronger ground.

An error in your property record — wrong square footage, a finished basement you don't have — feeds into either ground. Part of what we check is whether the county's record even matches your house.

Three ways to appeal, and which one fits

When you file a Fulton County appeal, you choose a path:

• Board of Equalization (BOE). Free, and the default. A panel of trained citizens hears your evidence and the county's, and sets a value. Right for most homes.
• Hearing Officer. Available for non-homestead property or homes valued over $500,000 — which covers a large share of Sandy Springs. Your case is heard by a certified appraiser rather than a citizen panel, which tends to suit higher-value, evidence-heavy cases.
• Binding arbitration. You submit a certified appraisal and the arbitrator picks between your appraisal and the county's value. Powerful, but you're paying for the appraisal up front.

Picking the wrong path isn't fatal, but picking the right one raises your odds. For what an appeal costs on each route — including the honest answer, which is usually "nothing up front" — see what a Georgia property tax appeal costs.

What a win is worth: three years, not one

A successful appeal doesn't just fix this year's bill. Under Georgia's 299(c) freeze (O.C.G.A. 48-5-299(c)), a value established through the appeal process is generally locked for the appeal year plus the next two — three years during which the county can't simply mark you back up. On a higher-value Sandy Springs home, that turns a one-time correction into a multi-year saving; the ~$4,500 median first-year figure from our data can compound to well into five figures over the freeze window. Full details in the Georgia 3-year tax freeze guide.

The honest Sandy Springs bottom line

Most Sandy Springs assessments are defensible, and if yours is one of them, appealing it wastes your summer. But the data says a meaningful minority of higher-value homes here are carrying values the market and the neighbors' assessments don't support — and the homeowners paying for those errors are usually the ones who never checked. The check is free, takes half a minute, and the deadline for most 2026 notices is July 31. Look at your number before the window closes.
