Buyers rarely ask me about property taxes before they write an offer. They ask about school districts, about lot lines, about whether the pool heater actually works. Property taxes come up later, usually about a year after closing, in the form of a letter from Fulton County that nobody was expecting.
Here is what that letter usually says, and what I wish every buyer knew before it arrived.
Your Purchase Price Becomes Public Record, and the County Notices
Georgia assesses real property at 40 percent of fair market value. When a home sells, that sale price becomes the strongest evidence of fair market value the county has, and Fulton County uses it. If you buy a home in Buckhead or Tuxedo Park for meaningfully more than the previous assessed value, expect your next Annual Notice of Assessment to reflect something close to what you actually paid.
This is not an error. It is not a targeted increase. It is simply how the system works, and at this price point, the gap between the old assessment and your purchase price can be significant.
The 45 Day Window Most Buyers Miss
Once that Notice of Assessment arrives, you have 45 days to appeal it. Miss that window, and you are living with that number for the year, regardless of how it compares to what similar homes nearby are actually assessed at.
An appeal can go through the Board of Equalization, through binding arbitration, or in some cases through a certified appraiser’s opinion of value, generally the more efficient route above a certain price threshold. Each path carries a different timeline and a different burden of proof. I am not an attorney or a tax professional, and I always recommend a qualified property tax attorney or appraiser for the appeal itself. What I can tell you, from watching this play out across enough closings, is that an appeal grounded in genuine comparable sales, not just a general objection to the number, is the one that tends to succeed.
A Successful Appeal Can Protect You for More Than One Year
Georgia law allows a successful appeal to freeze your assessed value for up to three years, which means the work of appealing correctly the first time is worth doing properly. I have seen buyers assume the appeal only affects the current tax bill, then miss the value of pushing for the right number the year it actually mattered most.
What I Tell Buyers Before They Ever Write an Offer
I would rather a buyer budget for this honestly than be surprised by it. If you are purchasing in the seven figure range in Buckhead, Tuxedo Park, or Chastain Park, I build the likely post-sale reassessment into the conversation about total cost of ownership, not just the closing statement. It changes how some buyers think about financing, and it should.
For sellers, the same information cuts the other way. A home with a documented, defensible assessment history is one less question for a buyer’s attorney to raise at the table.
If you are buying or selling in Atlanta’s luxury market and want to understand what a specific property’s tax picture actually looks like, that is a conversation I am glad to have before you are under contract, not after.
