Union County reassessment moves into Mifflinburg district, public meeting set May 14

County assessors are moving into the Mifflinburg Area School District, and Union County homeowners in Mifflinburg, New Berlin, Hartleton and the surrounding townships should expect property data collection to get more visible in their neighborhoods. The county says the reassessment work is now entering another phase in the district, part of a countywide project that covers 17,647 properties.

The county will explain the process at a Re-assessment Public Meeting set for Thursday, May 14, from 6 to 8 p.m. at Mifflinburg High School Auditorium. For homeowners who want the plain answer first, the county’s message is that the reassessment is meant to update property values to current market conditions and distribute the tax burden more fairly, not to raise taxes. Even so, new assessments can shift what individual property owners pay once the numbers are put into use for the 2028 tax year.

This is Union County’s first countywide property reassessment since 2006. The county says the new valuation date will be July 1, 2026, and Tyler Technologies is handling the work. That means county staff or contractors may soon be in the Mifflinburg district inspecting, recording, or otherwise updating property data as the project moves through the area. For residents, the practical step is to be ready for that visit and to use the May 14 meeting to ask how the county is handling their neighborhood.

The reassessment matters because Union County’s tax structure is spread across multiple local governments. The Union County Assessment Office says four school districts and most of the county’s 15 municipalities levy property taxes. In the Mifflinburg Area School District alone, that includes the boroughs of Mifflinburg, New Berlin and Hartleton, along with Buffalo, Hartley, Lewis, Limestone, West Buffalo and Union townships. A change in assessed value for a house on a Mifflinburg street or a farm in Lewis Township can ripple through county, municipal and school tax bills once the 2028 tax year arrives.

County officials tied the reassessment effort to a March cyberattack that destroyed critical data, which helped push the broader modernization effort. For homeowners, the immediate issue is not a future budget line, but a present-day visit from assessors and a public meeting that could shape how fairly Union County distributes property taxes for years to come.
