The individual/entity involvement requires a time commitment to establish
their selected state income tax capability. This is accomplished through
training from UDS; this training may be an initial presentation and continue

NOTE: UDS does not use any proprietary non-UDS software except for the
use of a browser and OS that comes with a computer. And so, all software
is proprietary UDS software; thus there are no software purchase requirements.
