The City of Newcastle requires businesses selling to or serving Newcastle residents to maintain a City Business License (this applies to businesses both with and without a physical address in Newcastle). Tax exempt 501(c)(3) nonprofit organizations are not required to obtain a license, but must file an application for informational purposes.
