Property Tax Grievance Guidelines vary widely by State and sometimes even by municipalities within a state.    A successful real estate tax appeal in most areas of the country is based upon first establishing the market value of your property. In order to reduce your property taxes you must prove that the value of your property is less than the valuation assigned by your assessing district (according to state law in most states, the assessment is deemed to be correct, and the burdon of proof, falls on the petitioner-homeowner to prove otherwise). A recent bonafide arms length sale of the subject property is the best evidence. If the property was not recently purchased, or the purchase was not at arms length (as in an inter-family sale, foreclosure or other sale made under conditions of distress), an appraisal by a state certified appraiser is the next best type of evidence, which is typically used to prove value of your home throughout the process.
