When working with a client related to a tax debt issue that has been contacted by the IRS and an immediate response is needed, I am able to bring in one of my partners from the American Society of Tax Problem Solvers.  This ensures that client issues are being addressed while I focus on other cases.  This partnership helps maintain client confidence that their issues are being addressed by a competent individual as well as me being kept in the loop.  I would first reach out to the client to explain to them that this person is a member of my team and has all of the qualifications needed to address their issues.  This prevents the client from thinking that they are working with a completely different company or being outsourced.
