Now that tax season is over, which clients should you let go?

Tax season is over! Looking back, you can see the difference between clients who helped your firm run well and clients who made every step harder.

That’s what makes now the right time to review client fit.

Most firms don’t wake up one day and decide to build a client list full of workflow headaches. Those things accumulate over time. 

• A long-time client gets a pass on deadlines. 
• A difficult return keeps getting squeezed in. 
• An old fee no longer matches the work.
• One exception becomes routine.

Before long, the practice is carrying extra weight and tax season makes that weight obvious.

Quick take for tax pros

• Post-season is the best time to evaluate client fit because the facts are still fresh.
• Not every difficult client should be disengaged. Some need firmer boundaries, revised fees or better guidance and processes.
• If a client pressures you to support an unsupported tax position, it becomes a practice protection issue.
• When disengagement is the right answer, handle it professionally with a disengagement letter.

Tax season reveals which clients your firm is carrying

Busy season has a way of exposing what your systems and staff are absorbing. A client who seemed manageable in November may have consumed outsized time in March. Another may have created repeated follow-up work or frustrated staff. A third may have paid too little for a return that required senior-level attention.

That does not automatically mean the client should go. But it does mean the relationship deserves a closer look while the details are still easy to recall.

A useful review asks a few practical questions. 

• Did this client respect deadlines? 
• Did they follow the firm’s process? 
• Did the fee reflect the actual work? 
• Did the engagement create stress disproportionate to its value? 
• Did the client increase compliance risk?

Those are practice-management questions, not emotional reactions. The goal is not to punish difficult people. It is about deciding whether each client still fits the firm you are trying to run.

Four client types that deserve a closer look

The disorganized client. This client sends partial information in waves, turning a standard return into a tracking exercise. Sometimes that can be improved with earlier communication or a rule that incomplete files move to extension. Sometimes it cannot.

The client who takes much longer than expected. Every firm has returns that look routine until they are not. Maybe the client calls repeatedly needing extensive explanation or requires unusual cleanup each year. If the time commitment is consistently high, the issue may be workflow- or pricing-related.

The client you’re undercharging. This is one of the most common post-season discoveries. A fee set years ago may no longer reflect complexity or inflation. Underpriced clients crowd out capacity that could be used more effectively elsewhere.

The client pushing unsupported positions. This client pushes weak deductions or wants you to sign off on positions they cannot support. This is not only frustrating; it serves as an ethical warning sign.

Can this client be reset, or is it time to disengage?

Some client relationships can be improved. A reset may be enough when the core issue is operational rather than ethical.

That reset might include better boundaries around calls and turnaround times. It might mean clearer deadlines for submitting documents. It might require revised fees that reflect the actual scope of work. It might also involve process changes, such as requiring organizers, portal use or completing submissions before work begins.

The key is consistency. If expectations are communicated but repeatedly ignored, the problem is becoming a pattern.

Disengagement becomes more likely when the client mistreats staff or ignores repeated expectations. At that point, keeping the client may cost more than the revenue they generate.

When client behavior becomes a practitioner risk

There is an important line between a demanding client and a risky one.

When a client pressures the preparer to support an unsupported tax position, the decision is no longer about customer service. It is about protecting the practice. Circular 230 and professional standards remind us a practitioner cannot simply accept a position because the client insists.

If the client minimizes the rules or expects you to “make it work,” that should be treated as a practice-protection issue. The reputational and compliance costs far exceed the value of the engagement.

How to part ways professionally

A professional disengagement should be clear and documented. It does not need to be dramatic. It should state that the firm will no longer provide services after a defined point, identify any immediate limits and avoid unnecessary detail or argument.

Documentation matters. Keep notes on the issues that led to the decision, especially if they involved repeated abusive behavior or pressure to take unsupported positions.

A disengagement letter is an important part of the process. It helps confirm the end of the relationship and reduces confusion about future filings and representation.

The importance of client review

Set aside time soon to review your client list with fresh facts. Look at realization, turnaround burden, staff impact and compliance concerns. Identify which clients can be improved through boundaries, deadlines, fees or process changes, and which ones no longer fit the practice.

A healthier firm is not built only by adding clients. Sometimes it is strengthened by deciding which relationships should change and which should end.
