For most DeKalb residents, the last day to file a property tax appeal is July 18, 2016 – and for most Fulton residents, the last day to file a property tax appeal is July 25, 2016.
Once you miss the deadline – it is over – no excuses are accepted – so go forth – file, file, file while you can. The county cannot raise your assessment because you file an appeal. You have a free shot at trying to get your assessment lower and if you fail, you can still freeze your existing assessment for the year appealed plus two more years. The only exception to filing an appeal is, in my opinion, unless there are extraordinary circumstances, you should not file an appeal during the time your property is under a freeze from a prior appeal.
