What a property tax appeal is

A property tax appeal is a formal, time-limited request to correct an assessed value using documented evidence. It is not a complaint letter.

Before your next conversation

  • Is your assessed value above recent comparable sales?
  • Do you know the appeal deadline for your county?
  • Do you have clean evidence to support a lower value?
  • Is the potential savings worth the time or fee?
  • Can you explain the case in one page?
Questions to bring to your professional
  • What is the appeal window and evidence standard for my county?
  • Would a professional appeal rep be worth the fee here?
  • Does a successful appeal carry forward to next year?
