Lancaster County has officially issued the 2027 Final Property Reassessment Notices as part of its countywide property reassessment, which will take effect for the 2027 tax year. The notices mailed to property owners are dated June 15, 2026, triggering an important and time-sensitive window for review and potential appeal.

The purpose of a reassessment is to equalize all assessed values of properties in Lancaster County to a current fair market value to ensure similar property types are assessed fairly and uniformly.

Appeal Deadline Now Running
Property owners have forty (40) days from the notice date to appeal their new assessed value if they disagree with the new value. Filing an appeal requires submission of an appeal form and a hearing before the Lancaster County Board of Assessment.

Key Considerations Before Appealing
Deciding whether to appeal a reassessment is a fact-specific analysis. Property owners should consider:

• Whether the County’s assigned value reflects current fair market value
• Sales of comparable properties and overall market conditions
• The strength of supporting evidence, including whether a professional appraisal is advisable

At this time, it’s difficult to determine whether the new assessed value will increase property taxes because the millage rates will most likely decrease in 2027 due to Pennsylvania law requiring tax revenue to remain neutral in a reassessment year. In the following years, taxing authorities may not increase taxes by more than 10%. However, those new millage rates will not be determined until December 2026 for county and municipal taxes and June 2027 for school taxes. Importantly, this 10% increase limit applies to the taxing authorities’ overall tax revenue – not to individual property taxes. Thus, property owners will not know the exact tax impact until the millage rates are finalized after the appeal deadline.

Next Steps for Property Owners
If you have received a 2027 Final Property Reassessment Notice, you should promptly review your new assessed value and be mindful of the appeal deadline. Because the window to act is limited, property owners considering an appeal or with questions about the reassessment process should seek guidance early. Failure to act within the deadline will generally result in the new assessment becoming final for 2027.
