About TSC

A firm built to solve problems, not just file returns.

TSC Enterprise is a certified public accounting and management consulting firm licensed in Maryland and the District of Columbia, working with businesses, nonprofits, individuals, and public-sector organizations across the Washington metropolitan area.

Why TSC exists

The firm was founded by Chris and Salome Tinker, both CPAs, who had spent their earlier careers inside large organizations—corporate tax departments, public accounting, standard setting, and financial reporting leadership. They saw the same pattern repeatedly: smaller organizations face the same technical questions as large ones, but rarely have access to anyone who has answered them at scale.

TSC was built to close that gap. Its tagline—We Solve Problems—describes the engagement model more accurately than any service list. Clients come with a situation, not a product code.

A note on the firm’s name: the origin of “TSC” has not been published by the firm. Rather than guess, this page leaves the explanation to be supplied directly by the partners.

Two divisions, one organization

TSC operates a CPA practice serving private-sector clients—businesses, nonprofits, and individuals—and a government-solutions division serving federal, state, and local organizations with financial management, audit readiness, organizational development, technical support, and professional training.

The two share leadership and standards but serve different buyers. This site covers the CPA practice; the government division maintains its own presence.

Philosophy

  • Understand the operation before advising on the tax position.
  • Document decisions so reporting can be defended, not explained away.
  • Answer in plain language, whether the listener is an owner or a controller.
  • Keep the professional responsible for the work available to the client.
  • Watch tax developments continuously rather than at filing season.
