Appeal Faster: Read Your Georgia Property Tax Assessment

Your Georgia Annual Notice of Assessment determines your property taxes, and you have just 45 days to appeal. This guide explains each section, from fair market value to exemptions and millage rates, so you can spot errors and decide whether to file.

Key Takeaways

  • **Your assessment is not your tax bill**: The Annual Notice of Assessment (PT-306) sets the value your tax bill will use, but final tax amounts depend on millage rates set later.
  • **You have 45 days from the notice date to appeal**: The clock starts when the notice is dated, not when you open it; circle that deadline immediately.
  • **Focus on the fair market value line**: Your assessed value is automatically 40% of fair market value, so the FMV is the number to compare against actual recent sales in your neighborhood.
  • **Check for missing exemptions**: If your homestead or senior/disability exemption code does not appear on the notice, contact your county tax office before the deadline passes.
  • **Verify property details for data errors**: Incorrect square footage, phantom bathrooms, or wrong property descriptions can inflate your assessed value and are common grounds for a successful appeal.

# How to Read Your Georgia Property Tax Assessment (Line-by-Line Guide)

When your Georgia property tax assessment shows up in the mail, it can feel like a wall of numbers and jargon — and you only get one short window each year to push back if it’s wrong.

This guide walks you through the Annual Notice of Assessment (PT-306) that Georgia counties send each year, and explains what each major field means so you can quickly spot errors and decide whether to appeal. (See a sample PT-306 notice from the Georgia Department of Revenue: PT-306 Annual Notice of Assessment.)

1. What this notice is — and what it isn’t

Across Georgia, your county’s Board of Assessors mails an Annual Notice of Assessment for every property. It shows their opinion of your property’s value as of January 1 of that tax year and how that value will be used to calculate your bill. (Example county explanation: Gwinnett County — Annual Notices of Assessment.)

On most notices, you’ll see language such as "THIS IS NOT A TAX BILL." That’s important:

If you disagree with the value, you must appeal the assessment, not wait for the tax bill.

2. Top of the notice: header and deadlines

Near the top right or top center, you’ll usually see:

The most important line in this area is your last date to file an appeal. Georgia law generally gives you 45 days from the notice date to file a written appeal with the county Board of Assessors. (Plain-English summary from an official state source: Georgia House — Summary of Appeal Process (O.C.G.A. 48-5-311).)

What to do here

3. Owner and property information

Usually in Box A or the top left, you’ll see details identifying the property:

What to check

If anything here is wrong, it can lead to missed notices or confusion if you appeal.

4. Current and prior year values

Georgia counties appraise property at fair market value as of January 1 (what a willing buyer would pay a willing seller in an arm’s-length sale). (Georgia DOR overview: Real and Personal Property FAQ.)

But property tax is computed on assessed value (40%), which is 40% of fair market value for most real estate classes. (Georgia DOR explanation and example math: Property Tax Millage Rates — How to Figure Tax.)

On your notice (often in Box B), you’ll typically see several value columns, often labeled like this:

Counties also explain this directly. For example, Fulton County states that assessed value is 40% of fair market value. (Fulton County Assessor FAQ.)

What to look for

- Compare previous year and current year fair market values. - Large jumps can happen, but they should be tied to real sales evidence.

- Ask: “Could I realistically sell my home for this amount today?” - If the number is much higher than what similar homes are selling for, you may have grounds to appeal.

- Incorrect square footage, extra bathrooms, finished basements that don’t exist — these can inflate the value.

5. Exemptions: homestead and more

Most Georgia notices have a section or column for exemptions. This is where your homestead exemption and any other special exemptions show up.

You might see:

Counties often emphasize that city, school, and county exemptions can differ. (See: Fulton County — Homestead Exemption Guide (PDF).)

What to check

If an exemption you qualify for doesn’t appear, contact the appropriate office (often the Tax Commissioner for exemption administration, depending on county).

6. Why did my value change?

Many Georgia counties include a field labeled something like “Reason for change in value.” It’s meant to explain whether the change was driven by market updates, new construction, record corrections, or another adjustment. (Example: Gwinnett — How to Read Your Annual Notice (PDF).)

Common reasons include:

Use this as a clue for what evidence you’ll need if you appeal.

7. Taxing authorities, millage, and estimated taxes

Most PT-306 notices include a section listing taxing authorities and estimated taxes. You’ll commonly see:

Georgia’s Department of Revenue explains how millage and assessed value combine to create your tax. (Georgia DOR — Property Tax Millage Rates.)

How to sanity-check the numbers

8. Appeal rights section

Somewhere on the front or back of the notice, there will be a section explaining your appeal rights and how to file.

A practical way to understand the basic timeline is this official summary document: Georgia House — Summary of Appeal Process (O.C.G.A. 48-5-311).

If you’re looking for the standard statewide form, Georgia provides a uniform appeal form (PT-311A), and the Department of Revenue specifically instructs homeowners to submit appeals to the county Board of Tax Assessors (not to the state). (Georgia DOR — PT-311A Appeal of Assessment Form.)

9. Other fields you may see

Depending on your county and property type, you might also see:

Counties sometimes publish an insert or explainer that matches the current year’s notice format. (Example: Fulton County — Annual Notice Insert (PDF).)

10. A quick review checklist

When your Georgia assessment arrives, you can walk through it in this order:

- Confirm tax year. - Find and mark your appeal deadline.

- Confirm the property, owner name, and mailing address are correct.

- Compare last year vs. this year’s fair market value. - Ask if it matches what your home could realistically sell for. - Confirm the 40% assessed value is consistent with the 100% value.

- Make sure your homestead and any special exemptions appear. - Verify they’re applied across applicable taxing authorities.

- Review the taxing authority lines, millage rates, taxable amounts, and estimated totals.

- If you disagree, identify the evidence you’ll use (recent comparable sales, condition issues, or county record errors). - File with your county Board of Assessors within the allowed window. (See: Georgia DOR — PT-311A guidance.)

11. Summary: From confusion to clarity

Georgia’s Annual Notice of Assessment looks intimidating, but once you know how to read each field, it becomes a structured story:

If the county’s numbers seem off — or if your exemptions are missing — that’s your cue to dig deeper, compare recent sales, gather documentation, and consider filing an appeal within the deadline.

Frequently Asked Questions

What is the PT-306 Annual Notice of Assessment in Georgia?
The PT-306 is the standardized form Georgia counties use to notify property owners of their assessed property value each year. It shows the county's opinion of your property's fair market value as of January 1, the 40% assessed value used for tax calculations, any exemptions applied, and your deadline to file an appeal. It is not a tax bill.
How long do I have to appeal my Georgia property tax assessment?
Georgia law generally gives you 45 days from the date printed on your Annual Notice of Assessment to file a written appeal with your county Board of Assessors. Missing this deadline typically means you must wait until the following year's notice to challenge your value.
What is the difference between fair market value and assessed value in Georgia?
Fair market value is the price your property would sell for in an arm's-length transaction between a willing buyer and seller. Assessed value is 40% of that fair market value for most residential property in Georgia. Your property tax bill is calculated using the assessed value, not the full fair market value.
How do I know if my Georgia property assessment is too high?
Compare the county's fair market value on your notice to recent sale prices of similar homes in your area. If comparable properties are selling for significantly less, your assessment may be inflated. Also check that the county's records accurately reflect your home's square footage, bedroom and bathroom count, and condition.
What exemptions should appear on my Georgia assessment notice?
If your property is your primary residence and you have applied, you should see a homestead exemption code. Senior citizens, disabled veterans, and other qualifying groups may have additional exemptions. These exemptions can differ across county, school, and city taxing authorities, so verify each line on your notice.
Where do I file a property tax appeal in Georgia?
Appeals must be filed with your county Board of Tax Assessors, not with the state. Georgia provides a standard appeal form called the PT-311A. You can typically file in person, by mail, or through your county's online portal within the 45-day window shown on your assessment notice.
What happens if my assessment notice has incorrect property details?
Errors such as wrong square footage, an extra bathroom, or an incorrectly listed finished basement can inflate your assessed value. Contact your county Board of Assessors to request a correction. If the error affects your fair market value and you are within the appeal window, you can also cite these data errors as grounds for your appeal.
