Scope of Services
Describe specific tax services (returns, representation, planning), including jurisdictions and tax years covered, and state excluded tasks to avoid ambiguity.
A formal engagement letter clarifies duties, sets fee terms, documents client obligations, and creates evidence of consent and scope. It limits exposure to disputes, supports professional standards, and provides a written basis for fees and deadlines.
Engagement letters are used across practice sizes from solo preparers to large firms; they apply whenever a tax practitioner provides services to a payor or client.
Use a written letter before substantive work begins and retain an executed copy for the client file to support compliance and recordkeeping.
