County Assessment Records
An assessment is a percentage of the appraised value of your property as of a specific date, called the "base year", which for Lehigh County is 2013, the effective date of the last County-wide reassessment. At that time, the County Commissioners selected the assessment percentage, known as the "predetermined ratio" to be 100% of the Fair Market Value. The Assessed Value is used as a basis for Real Estate tax. Throughout the year, the Assessment Office is responsible for maintaining the assessment rolls. This means that new assessments are added through new construction, and some assessments are reduced due to circumstances like razed buildings, fire damage, etc.
Property owners who are dissatisfied with the assessment of their property may file an appeal with the Board of Assessment Appeals. The Board of Assessment Appeals will only accept an "original" signed appeal received on or before August 1st of every year. Postmarks and faxed appeals will not be accepted as evidence of timely filing..
WHAT ARE THE ELIGIBILITY REQUIREMENTS? A property must be ten acres in size, and in Agricultural Use, Agricultural Reserve, or Forest Reserve. Agricultural Use applications may be less than 10 acres in size if the property is capable of generating at least $2,000 annually in farm income. 319 Application
