DeKalb County Property Tax Appeal Deadlines Explained

Why Appeal Deadlines MatterWhy DeKalb County Property Tax Appeal Deadlines Matter 

Every year, county assessors determine the fair market value of properties for tax purposes. If you believe your property has been overvalued, Georgia law allows you to file an appeal.

However, appeals must be submitted within a strict timeframe.

Failing to file before the deadline generally means:

  • The assessed value will stand for the tax year
  • You may lose the opportunity to seek a reduction
  • Your property taxes could remain higher than necessary

 

When Are DeKalb County Assessment Notices Sent? 

Assessment notices are typically mailed annually by the DeKalb County Board of Tax Assessors.

The notice includes:

  • Your property’s estimated fair market value
  • Assessed value for taxation
  • Prior year values
  • Appeal instructions
  • Filing deadline information

Because mailing dates can vary, homeowners should carefully review notices as soon as they arrive.

How Long Do You Have to File a DeKalb County Property Tax Appeal? 

In Georgia, property owners generally have 45 days from the date on the assessment notice to file an appeal.

This deadline is very important. The countdown usually begins based on the official notice date — not the date the notice is opened or reviewed.

What Happens If You Miss a DeKalb County Property Tax Appeal Deadline? 

If the appeal window closes before you file:

  • The county may reject your appeal
  • Your current assessed value will likely remain in place
  • You may need to wait until the next tax year to challenge the valuation

For this reason, homeowners should avoid delaying the review process.

  • Fair market value is too high
  • Property records contain inaccuracies
  • Unequal assessment compared to similar properties
  • Taxability issues

Many homeowners appeal after noticing that comparable homes in their neighborhood are assessed at lower values.

Strong evidence may include:

  • Comparable nearby sales
  • Independent appraisals
  • Repair estimates
  • Photos of property condition issues
  • Market analysis reports

The more detailed and organized the evidence, the stronger the appeal may be.

What Happens After Filing a DeKalb County Property Tax Appeal? 

After an appeal is submitted, several things may occur:

  • The assessor’s office may review the evidence
  • An adjusted value may be offered
  • Additional information may be requested
  • A hearing may be scheduled

The timeline can vary depending on the volume of appeals and the complexity of the case.
