Engagement Scope
Describe precisely which returns, tax years, or advisory services the preparer will deliver, and list excluded services to avoid scope creep.
A clear engagement letter protects both preparer and client by defining scope, fees, timelines, and responsibilities, reduces professional risk, and documents consent for electronic delivery and signature consistent with ESIGN and UETA principles.
Engagement letters are used by individual tax preparers, accounting firms, and clients across personal and business tax matters.
Use a signed engagement letter whenever you accept work, change the scope of services, or obtain authorization to represent a client before tax authorities.
Describe precisely which returns, tax years, or advisory services the preparer will deliver, and list excluded services to avoid scope creep.
Specify deliverables such as prepared returns, e-file transmission, client workpapers, representation at audits, and any consultative reports included.
State fee basis (fixed fee, hourly, contingent), billing schedule, late payment terms, and who pays filing or third-party costs.
List client duties: provide accurate records, timely responses, signer authorization, correct TINs, and full disclosure of relevant transactions.
Explain what copies the preparer retains, client file access, retention period, and how electronic records will be stored and transmitted.
State how to end the engagement, final billing, handling of incomplete work, and whether mediation or arbitration applies.
