The restructured Tayside Buses became employee-owned in 1991, was sold to National Express in 1997 and McGill's Bus Services in 2020, and today trades as Xplore Dundee.

Tayside Contracts services are open to the public and all profits from the company are equally fed back into each of the three councils to bolster revenue to the local authorities to provide cash for services as a boost to central government and council tax income.
