Every spring and early summer, Georgia homeowners receive a Notice of Assessment from their county Board of Tax Assessors. This notice sets the assessed value that will determine your property tax bill — and you have exactly 45 days from the date on the notice to decide whether to appeal. Many homeowners glance at the notice, set it aside, and miss their window entirely. Here is a complete guide to reading your Georgia Notice of Assessment and deciding whether to file an appeal.
What Is a Georgia Notice of Assessment?
A Georgia Notice of Assessment is the official communication from your county Board of Tax Assessors informing you of your property's assessed value for the upcoming tax year. Under Georgia law (O.C.G.A. § 48-5-306), your county is required to send this notice annually or whenever your property's assessed value changes. The assessed value on this notice is used to calculate your annual property tax bill — it is not the market value of your home. Georgia law requires assessment at 40% of estimated fair market value.
Key Lines on Your Georgia Notice of Assessment
Georgia Notices of Assessment vary slightly by county, but all contain the same core information. Here is what to look for:
- ✓Notice Date: The date printed here starts your 45-day appeal clock — not the postmark date or the date you received it
- ✓Property ID / Parcel Number: Your unique identifier with the county assessor
- ✓Prior Year Assessment: Your assessed value from the previous year — compare to identify any increase
- ✓Current Year Assessment: Your new assessed value — this is 40% of the assessors' estimated fair market value
- ✓Fair Market Value Estimate: Some notices list this separately — what the assessors believe your home would sell for
- ✓Appeal Deadline: Your specific 45-day deadline — confirm this carefully
How to Calculate What Your Assessment Means for Your Tax Bill
To estimate your annual property tax bill: (1) Take your assessed value from the notice. (2) Subtract any applicable exemptions (homestead exemption is most common). (3) Divide by 1,000 to get your taxable value per mill. (4) Multiply by your county's total millage rate. For example: assessed value $200,000 minus $10,000 homestead exemption = $190,000 taxable. At a combined millage rate of 28 mills: ($190,000 / 1,000) x 28 = $5,320 estimated annual bill.
When Should You Appeal?
You should seriously consider appealing your Georgia property assessment when:
- ✓Your assessed value divided by 40% implies a fair market value significantly higher than what your home would actually sell for today
- ✓Comparable homes in your neighborhood have sold recently for less than the implied market value on your notice
- ✓Your assessment increased significantly from last year without a corresponding increase in actual market value
- ✓Your property record contains errors — wrong square footage, bedroom count, pool status, or lot size
- ✓Your home has condition issues, deferred maintenance, or defects that reduce its value below the assessment
The 45-Day Deadline Is Absolute
Georgia's 45-day property tax appeal window has no grace period and very limited exceptions. The deadline runs from the date printed on your notice — not the date you received it. If you mail your appeal, it must be postmarked before the deadline. TaxAppeal USA files all appeals via USPS Certified Mail with Return Receipt to create documented proof of timely filing. Missing the deadline means waiting a full year.
Frequently Asked Questions
When does my Georgia property tax appeal deadline start? ▾
Your 45-day window starts from the date printed on your Notice of Assessment — not the postmark date or the date you received it. Check the notice date carefully, count 45 calendar days, and that is your deadline.
What if I never received my Georgia Notice of Assessment? ▾
Contact your county Board of Tax Assessors immediately to request a copy. Your appeal deadline still runs from the original mailing date even if you did not receive the notice.
What does the 40% assessment ratio mean? ▾
Georgia law requires county assessors to value property at 40% of its estimated fair market value. If your home is worth $400,000 in the market, your assessed value should be approximately $160,000.
Can I appeal if my assessment stayed the same? ▾
Yes. You can appeal your Georgia assessment every year regardless of whether it increased. If your current assessed value implies a fair market value higher than what your home would actually sell for today, you have grounds to appeal.
What happens after I file a Georgia property tax appeal? ▾
The county Board of Tax Assessors reviews your appeal and evidence. They may offer an informal reduction or schedule a Board of Equalization (BOE) hearing.
