We are required by law to maintain your records for a certain period of time. Please inform us if you would like us to transfer these records to another firm, and we will make those arrangements. 

We kindly request that you respond to this letter to confirm you have received and read it thoroughly. You can reach us at [phone number] or email us at [email address] if you have any further questions. We appreciate your understanding and are committed to making this transition period as smooth as possible.

Accountant and CPA Client Termination Letter Example

When a CPA or accountant ends a client relationship, the letter should be short, professional, and specific about dates. Here is a sample you can adapt:

Dear [Client name],

This letter confirms that [Firm name] will no longer provide accounting and bookkeeping services to [Client business] effective [date]. We will complete [list any work in progress] by that date and will not begin new work after it.

Your records, including [list documents], will be returned or made available for download by [date]. Please let us know where to send them and confirm any outstanding invoices, which are due by [date].

When an Accountant Should Consider Firing a Client

• Repeated late or missing records that make deadlines impossible to meet.
• Unpaid invoices after reasonable reminders.
• Requests to do anything that conflicts with professional or ethical standards.
• Scope that has grown far beyond the agreement without a fee adjustment.
• Disrespectful treatment of your team.

Check your engagement letter for the notice period before you send the termination letter, and time it so the client is not left mid-filing.

4 Key Elements to Ensure Your Termination Letter Is Received Well by the Client

No matter your reasons for doing so, informing clients you will no longer work together is never easy for either party. 

Therefore, how you write the termination letter can largely determine how your client responds to this transition. To effectively handle this communication, incorporate the following elements into your termination letter. 

Give Ample Notice

Provide your clients with enough notice before terminating the business arrangement. You’ll need to give them enough time to find another provider. Sending the termination letter out last minute not only comes off as inconsiderate to the client but can also make you look unprofessional.  

Once you’ve made the decision to no longer work with a client, you should inform them as soon as possible. 

If you give your client a few months’ notice that you will be terminating the contract, they should have plenty of time to make different arrangements for their accounting services. 

Be Professional and Respectful

Maintain a professional and respectful tone throughout your termination letter, even if there was a negative reason for ending the relationship. 

You will help maintain your firm’s professional reputation despite dealing with something complicated and challenging. If appropriate, you can even thank the client for all the time they’ve worked with you and share how much you have appreciated their loyalty. 

Understand the client may have frustrations about their contract ending, so be sure to reflect this sentiment in your termination letter without focusing too much on the negative.  

“We understand that this period of transition may be difficult for everyone. We’ve appreciated your loyalty to our firm for the past 8 years, and we don’t make this decision lightly.”

Provide a Reason Why

You should also include your reasoning for canceling the business contract or engagement with the client. If possible, avoid being harsh with the client, even if they’re the bad actor. 

Don’t make your clients guess why you’ve ended their contract. Whatever the cause, be direct with your message. Being too vague may only confuse the client or lead them to use their imagination to figure out the reason. 

“We will no longer be able to provide you with our monthly bookkeeping services effective [date]. We are pivoting the direction of our firm and discontinuing this service for all existing clients.”

Summarize the Next Steps

To finish your letter, detail any of your firm’s outstanding obligations or payments that need to be fulfilled by the client before ending the relationship. Make these details extremely clear so there is no confusion across the board.

Be sure to inform them how long you will retain their documents and information for recordkeeping purposes and how they can transfer those records to a new firm when necessary. 

Lastly, request confirmation from the client that they’ve received the letter and understand its contents. Include your contact information should they have further questions about the letter and the next steps.  

“Your final invoice will be due 15 days following the termination date of service, [date]. If you have any additional questions about the contents of this letter, you can reach us at [phone number] or email us at [email address].”

Frequently Asked Questions

How much notice should an accountant give when terminating a client?

Follow the notice period in your engagement letter. Thirty days is common, and longer is courteous when a filing deadline is close.

What records must be returned to a terminated client?

The client's own documents and any deliverables they have paid for. Your working papers generally remain yours, but check your professional body's rules.

Should the termination letter give a reason?

It does not have to. A short, neutral statement with clear dates is usually best.

What is a disengagement letter?

A disengagement letter is the letter an accountant or CPA sends to end a client relationship in writing. It states the end date, the work completed, the deadlines the client now owns and how records are returned.

Can an accountant drop a client in the middle of tax season?

Yes, but give as much notice as you can and list every deadline the client must now meet. Check your engagement letter and your professional body’s rules first.

How do I send a client termination letter?

Send it by email and by a mail service with proof of delivery, ask the client to confirm receipt, and keep a copy in the client file.
