What can change your bill?

The ACS effective rate is a ratio of medians, not a statutory rate. Local assessed values, levies, classification, caps and exemptions determine the actual bill.

Exemptions & assessment

Basic state homestead exemption on assessed value; county and municipal exemptions differ.

Payment dates & appeals

State guidance describes December 20 as the normal date in most counties, but county dates can differ. Taxpayers receive 60 days from billing; check the county tax commissioner notice.

File a written assessment appeal with the county Board of Tax Assessors within 45 days of the date the annual assessment notice was mailed. This is separate from paying a tax bill.

Check Georgia’s official property-tax guidance

Official local guidance

The appraisal office explains the 40-percent assessment base. School, county and applicable city millages are separate components of actual taxes.

Read the official guidance

Use an assessed value, exemption, and local millage

This separate scenario needs your assessor’s inputs. An exemption applies only to eligible levies; do not apply it to the county’s historical effective rate.

1 mill = $1 per $1,000 of taxable assessed value.

Good questions. Clear answers.

How much is property tax on a $300,000 home in DeKalb County?

The historical effective-rate estimate is $2,775 per year, or $231 a month. It multiplies $300,000 by 0.93%.

Is the effective rate the rate on my tax bill?

No. It is median real-estate taxes paid divided by median home value in the ACS 2020-2024 survey. Your taxing districts, assessed value, classification and exemptions determine your bill.

Can I subtract a homestead exemption from this estimate?

Use the separate statutory scenario with a qualifying levy. Subtracting an exemption from an ACS effective-rate estimate can double-count relief already reflected in taxes paid.

Does a higher purchase price change my assessment?

Assessment rules and reassessment dates vary by state and locality. Contact the linked official property-tax office before relying on a historical county ratio.

How do I appeal a property-tax assessment?

Read the deadline and procedure on your assessment notice, then use the official state guidance above to locate your assessor or review board. County survey data does not establish your appeal deadline.
