Lancaster County mailed out its 2027 Final Property Reassessment Notices (“Notices”) on June 15, 2026. Accordingly, because this is technically an interim assessment, you would have 40-days from the June 15, 2026 mailing date to file an interim assessment appeal, which would be July 25, 2026. See 53 Pa.C.S. § 8848(c)(1). However, since July 25, 2026 falls on a Saturday, you would have until the next business day, which would be July 27, 2026 to timely file an appeal of your new reassessed value.
Lancaster County notes on its Notices that “[R]eassessment Appeals for the 2027 property tax year will have a deadline of August 3, 2026 as the first business day after August 1st.” (emphasis added). I would be very weary of that date, and I would highly recommend filing an appeal on or before July 27, 2026 to be safe.
The new assessed values will be effective January 1, 2027, for county and municipal real estate taxes and July 1, 2027, for school district real estate taxes.
