Lancaster County, Pennsylvania 2027 Reassessment Notification

Lancaster County, Pennsylvania recently announced it will be conducting a county-wide reassessment for the 2027 tax year. The reassessment will be conducted by Certified Pennsylvania Evaluators (CPE) that the county employs on a full-time basis.

Lancaster County property owners can expect to receive notices in the mail with their new 2027 assessed values in June 2026. Pennsylvania statute requires reassessments to be revenue-neutral on a county level, so the millage rates will decrease in conjunction with the increase in assessed values. By Pennsylvania statute, millage rates must be lowered in a reassessment year.

The taxing jurisdictions (i.e., county, municipality, and school districts) cannot collect more taxes than they did the previous year as a result of the reassessment. A taxing district may then, by a separate vote, choose to adjust its millage rate if it needs to collect additional taxes. The law caps the additional taxes at 10% of the total amount collected in the previous tax year. Despite the reassessment being revenue-neutral on a county-wide basis, some properties will see an increase in real estate taxes because of the reassessment, while others will see their taxes decrease. There will be a 40-day appeal window from the mailing date of the new value notice following the reassessment in addition to the regularly scheduled annual appeal deadline of August 1 for Lancaster County.

The last county-wide reassessment for Lancaster County was effective July 1, 2018. The county adopted a seven-year reassessment schedule in 1997, and the originally planned 2025 reassessment was delayed two years to 2027.
