PTAA, LLC charges an upfront flat fee as noted in our letter, and no other fees. We guarantee that your assessed value will be reduced for the tax year we work on or we will refund your fee. The amount of your property taxes is based on the assessed value of the property, so the lower your assessed value, the lower your property taxes.
