Receiving your Annual Notice of Assessment from DeKalb County might not be the highlight of your mail, but it demands your immediate attention. This document contains vital information about how the county values your property for taxation, and it ignites a critical 45-day countdown – the limited time you have to formally challenge that assessment if you believe it's inaccurate.

Ignoring this deadline can result in being locked into a potentially inflated property tax bill for the entire year. Therefore, understanding the significance of this 45-day window and knowing what steps to take is paramount.
What is the Annual Notice of Assessment?
This notice, typically mailed by the DeKalb County Tax Assessor's Office, provides a detailed breakdown of your property's valuation, including:
- The county's current estimate of your property's Fair Market Value (FMV) as of January 1st of the tax year.
- The assessed value, which is 40% of the FMV for residential properties in Georgia.
- Any homestead or other exemptions you are currently receiving.
- The all-important 45-day deadline for filing an appeal.
Why is the 45-Day Deadline So Critical?
This isn't merely a suggestion; it's a strict legal requirement dictated by Georgia law (Official Code of Georgia Annotated 48-5-311). Once this 45-day period expires, your legal avenue to formally dispute the county's valuation for the current tax year generally closes. You will be obligated to pay property taxes based on the county's assessment, even if you believe it to be excessive, until the next assessment cycle.
What Triggers the 45-Day Countdown?
The clock begins ticking from the "Notice Date" clearly printed on your assessment notice. Be careful not to confuse this with the date you actually receive the notice in your mailbox – the official mailing date is what initiates the countdown.
What Happens If You Miss the Deadline?
Regrettably, missing the 45-day deadline typically means you forfeit your right to appeal the assessed value for the current tax year. You will be responsible for paying property taxes based on the county's valuation, even if you have valid reasons to believe it's too high.
What Should You Do Within the 45-Day Window?
- Open and Review Immediately: Don't let the notice linger. Open it promptly and carefully examine the assessed value and the appeal deadline.
- Conduct Your Own Research: Investigate recent sales of comparable properties in your DeKalb County neighborhood. Does the county's FMV align with your findings? Consider factors such as your property's size, condition, age, and specific features. Online real estate portals and the DeKalb County Tax Assessor's website (https://dekalbtaxassessor.com/) can be valuable resources.
- Identify Potential Errors: Double-check the property details on your notice for any inaccuracies (e.g., incorrect square footage, number of bathrooms, etc.).
- Gather Supporting Evidence: If you believe your property is overvalued or unfairly assessed compared to similar properties, begin compiling evidence to support your claim. This might include:
- Sales data of comparable properties that sold for less.
- Photographs or documentation of property defects or necessary repairs.
- Independent appraisals (if you choose to obtain one).
- File Your Appeal: If you have valid grounds for an appeal, don't procrastinate. You can typically file your appeal online through the DeKalb County Tax Assessor's website (https://dekalbtaxassessor.com/), which is often the most efficient method. You can also mail a completed appeal form (available on the website) to the address provided on the notice. Ensure it is postmarked within the 45-day window.
