Henry County Property Tax Appeal, Georgia

Travis BunnTravis Bunn·Updated July 24, 2026

Henry County, Georgia is a rapidly growing suburban county located just south of Atlanta, with McDonough serving as the county seat. The county includes major population centers like Stockbridge, Hampton, and Locust Grove, and has become a popular residential choice for Atlanta commuters. With a median home value of $321,100 and an effective property tax rate of 1.15%, property owners face higher tax burdens compared to both the national median rate of 1.02% and median annual tax bill of $2,400, making property tax appeals particularly important for homeowners seeking relief. The county's median annual tax bill of $3,597 is $1,197 above the national median, and the effective tax rate places Henry County 6th highest among Georgia's 159 counties.

On the typical Henry County home, valued near $321,100 at the county’s effective tax rate of 1.15%, an over-assessment of even 10% means you are overpaying year after year until you appeal it. Here is how to find out if yours qualifies.

2026 Appeal Deadline: 45 days from the mailing date of the notice of assessment

How Henry County Assesses Property

40%of market value

Assessed by: Henry County Board of Assessors

Assessment cycle: annual

Notices typically mailed: April-May

In Georgia, property is assessed at 40% of fair market value. For example, if your home's market value is $321,100 (Henry County's median), at Georgia's 40% assessment ratio your assessed value would be $128,440, resulting in approximately $3,597 in annual taxes at the county's effective rate of 1.15%. Property taxes are calculated by multiplying the assessed value by the millage rate set by the county, school district, and other taxing authorities.

The Appeal Process

Appeals are heard by the Board of Equalization. The Board of Equalization is a panel of local citizens trained to handle tax disputes. During the hearing, you'll have approximately 15 minutes to present your case, show comparable property sales, discuss property condition issues, and explain why you believe your assessment is incorrect. The Board will review your evidence, may ask questions, and will typically mail their decision within 30 days of the hearing.

1

Step 1: Review your assessment notice when it arrives in mid-April or May and compare your assessed value to similar properties in your area using the county's QPublic portal at https://www.qpublic.net/ga/henry/search.html

2

Step 2: File your appeal within 45 days from the mailing date of your assessment notice by submitting a written letter of disagreement or appeal form to the Board of Assessors, either in person or by mail (no email or fax). Include your Property ID Number, property description, and grounds for appeal (typically 'Value').

3

Step 3: Gather supporting evidence including recent comparable sales of similar properties, photographs showing property condition issues, repair estimates, or appraisal reports that support a lower market value.

4

Step 4: The Board of Assessors will review your appeal and may offer an informal review to discuss your concerns. If no agreement is reached, your appeal will be forwarded to the Board of Equalization for a formal hearing.

5

Step 5: Attend your Board of Equalization hearing where you'll have approximately 15 minutes to present your evidence. The Board will review your case and typically mail their decision within 30 days of the hearing.

6

Step 6: If you disagree with the Board of Equalization's decision, you may appeal to Superior Court within 30 days. Alternatively, Georgia offers arbitration or hearing officer options as alternative appeal paths.

7

Step 7: If your appeal results in a value determination (even if unchanged), Georgia law provides a 3-year value freeze, meaning your assessed value cannot increase for three years unless you make improvements to the property.

What happens at a Board of Equalization hearing in Henry County?
At a Board of Equalization hearing in Henry County, you will appear before a panel of trained local citizens who are charged with hearing property tax appeals. You'll have approximately 15 minutes to present your evidence, which may include recent comparable sales, photographs of property condition issues, repair estimates, or appraisal reports explaining why your assessment is too high. The Board members may ask questions about your property or evidence, and a representative from the Board of Assessors may also present their position.

How much can I save by appealing my property taxes in Henry County?
The savings from a successful property tax appeal in Henry County depends on how much your assessment is reduced. With Henry County's effective tax rate of 1.15%, every $10,000 reduction in your home's assessed market value saves approximately $115 annually in property taxes.

Additionally, even if your appeal doesn't result in a reduction, Georgia law provides a 3-year value freeze, protecting you from assessment increases for three years, which can save hundreds or thousands of dollars in a rising market.
What evidence do I need for a Henry County property tax appeal?
The most effective evidence for a Henry County property tax appeal includes recent comparable sales (sold within the past 12 months) of similar homes in your neighborhood that demonstrate a lower market value than your assessment. You should also gather photographs documenting any property condition issues, defects, or needed repairs, along with contractor estimates or repair quotes showing the cost to fix these problems. Other valuable evidence includes a professional appraisal report, documentation showing errors in your property's characteristics (such as incorrect square footage or lot size), and evidence of assessment uniformity issues if similar properties are assessed at lower values. You can research comparable sales using Henry County's QPublic portal at qpublic.net/ga/henry.
Can I file my Henry County property tax appeal online?
Currently, Henry County does not offer a fully online property tax appeal filing system. All appeals must be submitted either in person at the Henry County Tax Assessor's Office at 140 Henry Parkway in McDonough, or by mail to the same address, and must be postmarked within 45 days of your assessment notice mailing date. Email and fax submissions are not accepted under Georgia law and county policy. However, you can access valuable property information and research comparable sales online through the county's QPublic portal at https://www.qpublic.net/ga/henry/search.html to help prepare your appeal evidence before filing.
Do I still have to pay my property tax bill while my appeal is pending in Henry County?
Yes, you must still pay your property taxes while your appeal is pending in Henry County. If your appeal is not resolved before tax bills are mailed, you will receive a bill for 85% of the disputed amount, which is due by the normal deadline regardless of your pending appeal. Once your appeal is resolved, if the assessment is adjusted, you will receive either an additional tax bill for any balance due or a refund if you overpaid. Failure to pay the 85% bill on time can result in penalties, interest, and potential tax liens, so it's critical to pay even while actively appealing your assessment.
