Learn moreA comparatively elevated combined 1.70% local Earned Income Tax
Chambersburg Area School District residents pay a real, current combined 1.70% local EIT (1.20% to the school district, 0.50% to the borough), collected by the Franklin County Area Tax Bureau -- a real, comparatively elevated combined local rate relative to several other Pennsylvania Tier B markets built in this same pass.
A real, disclosed source anomaly in Franklin County's effective property tax rate
One Ownwell citation reported an implausible 16.33% median effective property tax rate -- almost certainly a data-scraping or unit error, since the same source's own $3,087 median annual bill is mathematically consistent with a rate near 2%, not 16%. This record uses PropertyTaxPeek's far more plausible 1.99% figure as its primary, canonical number, and discloses the conflicting Ownwell citation explicitly rather than silently omitting or blindly repeating it.
Franklin County's distinctive 1961-vintage assessment lag
Franklin County's last full countywide reassessment took effect in 1961; the county's 2025-2026 common level ratio (CLR) ran 13.89, meaning current assessments average only about 7% of true current market value. Nominal millage -- Franklin County's own 2026 rate ran 29.1 mills plus a 1.3-mill library levy; Chambersburg Borough levies 35.5 mills; county school districts range roughly 114-136 mills -- is applied against these decades-lagged assessed values.
Pennsylvania's flat 3.07% state income tax and statewide insurance profile apply
Layered on the combined 1.70% local EIT, Pennsylvania's flat 3.07% state income tax produces a real combined approximate marginal rate of 4.77%. Chambersburg shares Pennsylvania's statewide homeowners-insurance profile (no documented crisis, premiums running $851-$1,893/year depending on source).
