Office Locations

In response to the COVID-19 pandemic, Keystone is following the CDC and Pennsylvania Health Department Guidelines on social distancing to limit the spread and exposure of coronavirus. Most Keystone community offices will therefore be closed to the public during this unprecedented time.

All other avenues of normal taxpayer communication and public information access remain open, including online, via telephone and by mail. If you have questions or need local tax assistance, please contact Keystone via email through the Contact Us page or call the Taxpayer Service team at 724-978-0300. Thank you.
