Scope of Work
Specify exact services: planning, return preparation, audit representation, and any exclusions or assumptions.
A precise engagement letter reduces scope creep, protects both the taxpayer and the advisor, and documents expectations that affect timing, fees, and legal responsibility. It creates an audit-ready record that can support fee disputes and professional standards reviews.
Common users include tax preparers, CPA firms, enrolled agents, bookkeeping services, and small to mid-sized businesses entering into paid tax advisory or representation agreements.
Tailor the letter to reflect the role (advisor vs subcontractor), business entity type, and any industry-specific obligations before signing.
Specify exact services: planning, return preparation, audit representation, and any exclusions or assumptions.

State start date, key milestones, and deadlines tied to tax filing or client data delivery.
Name authorized signatories, agent authority, and who may provide instructions on behalf of the business.
Define data handling, privacy obligations, and any HIPAA or client-specific protections.
