Let’s break down the key components of your Gwinnett County notice, section by section:

1. 🧍 Property Owner(s) and Mailing Address

Your Name(s): Lists the legal owner(s) of the property. Double-check for accuracy.
Mailing Address: Confirm this is your correct current mailing address, especially if you’ve moved recently.

2. 🏡 Property Identification

Property Address: The physical location of the property. Ensure it's accurate.
Tax Parcel ID (PIN): A unique ID assigned by Gwinnett County. You’ll need this number to file an appeal or look up details online.
Legal Description: A technical description of the land (e.g., subdivision, lot/block). This is more relevant for legal purposes than everyday use.

3. 📊 Assessment Information

Current Fair Market Value (FMV): The Tax Assessor’s estimate of your property's market value as of January 1 of the current tax year.
Previous Fair Market Value (if shown): A point of comparison to help you identify increases in value.
Assessed Value: In Georgia, this is 40% of the FMV:

Assessed Value = Fair Market Value × 0.40
Previous Assessed Value: This shows the prior year’s assessed value for comparison.

📝 Important: Tax bills are calculated based on the assessed value, not the FMV.

4. 🛡️ Exemptions (If Applicable)

Exemption Type(s): Includes Homestead, Senior, Veteran, or other exemptions.
Exemption Amount(s): How much is deducted from the assessed value due to exemptions.
Net Taxable Value: The assessed value minus exemptions.

Net Taxable Value = Assessed Value − Exemptions

📌 This is the number to which millage rates will be applied to determine your tax bill.

5. 📅 Important Dates & Deadlines

Date of Notice: The official mailing date.
Appeal Deadline: Usually 45 days from the date of notice. This is your only window to challenge the valuation.
Tax Bill Mailing Date: Typically later in the year (often around August or September).
Tax Payment Due Date: Usually in two installments (e.g., October and December), but check each year for exact dates.

⚠️ Missing the appeal deadline forfeits your right to dispute the value until the next year.

6. ⚖️ Appeal Information

This section outlines your appeal rights:

Your Right to Appeal: You can challenge the valuation if you believe it’s inaccurate.
Appeal Options in Gwinnett County:
- Board of Equalization (BOE): A free hearing with a citizen panel.

- Hearing Officer: For non-homestead properties over $500,000.
