How to create a tax return letter for clients - banner

As the sun rises on another hectic tax season for accountants, many wish they had a magic wand to do some of the busy work. One such task is creating and sending tax return letters to clients.

Sending out a tax return letter to your clients before tax season establishes clear and formal communication, ensuring that everyone understands and is aligned on expectations, deadlines and the requirements to move forward. It’s also a friendly reminder to clients that you’re actively working for them.

In this article, we will provide you with the necessary information to create an engaging and comprehensive letter — and even provide you with examples and a template to use in your upcoming busy tax season

What is a tax return letter?

A tax return letter is an engagement letter you send to clients to initiate the process of preparing their returns. It serves as a reminder to clients of what to expect and details the steps and requirements for a successful filing.

It can also serve as a form of marketing, reminding clients of your services and fees — and that you’re ready to help. Of course, in the digital age, you can also email a tax return letter.

Key components of a tax return letter

While each firm’s letter may vary slightly, there are several key components you’ll want to include.

  1. A professional header and greeting: include your firm’s branded header and open your letter with a kind and formal salutation that sets a professional tone. 
  2. An introduction of your purpose: the opening paragraph(s) should clearly state the letter’s purpose. It introduces the upcoming tax season and your firm’s role.
  3. An outline of services: detail the specific services you provide. This could range from basic tax return preparation to more comprehensive services like tax planning and consulting for the future. 
  4. Your fee structure: provide a summary of how you bill for your services. Include any additional fees, required deposits and payment terms. Providing as much transparency as possible helps keep clients happy and returning. 
  5. Terms and conditions: these include the formal terms of the engagement, outlining the responsibilities and expectations of both your firm and the client, and any legal considerations relevant to the services you provide.
  6. A document checklist: offer clients a comprehensive checklist of what they need to get started. This makes the process easier for you and the client, preventing endless back-and-forth communication and missing documents. 
  7. Key deadlines and time frames: remind clients of the deadline for when their taxes must be filed and inform them of when you’ll need to receive their documents in order to file on time. Also, offer them approximate time frames for how long you will take to prepare their taxes once you receive all the necessary documents. Inform them that if they cannot provide the documents by the deadline, you’ll have to file for an extension, adjusting the time frame for when their taxes will be complete and possibly incurring additional fees.
  8. An accuracy declaration: ultimately, a client is responsible for the accuracy of their tax return, so remind them they’ll need to review it before signing.
  9. Closing remarks and contact information: conclude your letter with a polite closing and contact details, encouraging them to contact your firm if they have any questions. 
  10. A signature field: provide a field for your clients to formally accept the terms of your service by signing and dating at the end.
