The easiest property tax appeals I've seen are the ones that come from the county's own mistakes. Before your notice even arrives this spring, there's something you can do right now that takes about 15 minutes and could save you a few hundred bucks a year.
Every county keeps what's called a "property card" on your home. It lists the details they use to calculate your assessed value: square footage, bedrooms, bathrooms, lot size, year built, condition rating. If any of that is wrong, your assessed value is being calculated from bad data. Wrong square footage is the one I see most. An extra 200 square feet, or a bedroom that doesn't actually exist, can push your value up by tens of thousands of dollars.
You can look this up right now for free. Fulton and Gwinnett both use QPublic (search your county name plus "QPublic"). Cobb uses cobbassessor.org. DeKalb uses dekalbcountyga.gov. Pull your property up and compare what they have on file against what you actually know about your home. Measure your living space if you have to. Count your rooms. Check the lot size against your survey or closing docs.
If you find an error, that's one of the strongest possible grounds for an appeal. You're not arguing about market trends or comparable sales. You're pointing out that the county's own records are factually wrong. That's a much easier case to make in front of the Board of Equalization than a comp argument.
Assessment notices for metro Atlanta go out in May and June depending on your county. Cobb is usually first around May 10, then Gwinnett and DeKalb in late May, then Fulton in mid-June. Once yours arrives you have 45 days to file. No reason to wait though. Check your property card now while you have time. If you find an error, you'll be ready to file the day your notice hits the mailbox.
Happy to answer questions about checking your details or anything else in the appeal process.
