The Firm will not prepare or file tax returns under this engagement unless expressly agreed in writing.

Client Responsibilities

The client agrees to provide complete and accurate information necessary for the Firm to perform the engagement. The client is responsible for the accuracy and completeness of all data and for maintaining adequate documentation to support tax positions.

Limitations, Conflicts and Termination

The Firm will not render opinions beyond the scope of the engagement.

What the Tax Advisory Group Engagement Letter Is

The Tax Advisory Group Engagement Letter is a written agreement that sets out the scope, responsibilities, timing, fees, and deliverables for tax advisory services provided by a firm or group to a client. It defines engagement parameters such as authorized contacts, document access, confidentiality expectations, and dispute resolution, and it clarifies whether the advisor will prepare filings, provide tax planning, or represent the client before tax authorities. The letter creates a record for both parties to manage expectations, limit scope creep, and support professional standards and billing.

Why a Clear Engagement Letter Matters

A written engagement letter reduces misunderstandings, documents consent to services, and supports fee transparency while helping satisfy professional and regulatory standards such as IRS guidance and professional conduct rules.

Why a Clear Engagement Letter Matters

Who Typically Uses This Engagement Letter

Typical users include tax firms, in-house finance teams, CPAs, and clients hiring outside tax advisors for planning or representation.

  • Tax advisory firms and CPAs engaged to prepare returns or provide representation
  • Corporate finance or tax departments retaining external specialists for complex matters
  • Individuals or small business owners contracting one-time or ongoing tax planning services

Use the letter anytime services are agreed in writing to document scope, billing, limitations, and signature authority.

  • Omitting fee terms, payment schedule, or early-termination consequences, which can create collection issues and unclear client expectations.
