When to Fire Your CPA: 7 Warning Signs

Most business owners keep the same accountant for years out of inertia, not satisfaction. Switching feels disruptive, and it is hard to know what you do not know. But a CPA relationship that only produces an accurate return each spring, without ever proactively reducing what you owe, is costing you money every single year it continues. Here are seven signs it is time for a change.

1. You Only Hear From Them Once a Year

If your only meaningful interaction with your accountant happens during filing season, you have a tax preparer, not a tax strategist. Nearly every valuable planning opportunity, entity elections, retirement plan design, equipment purchase timing, has a deadline that falls well before April. An advisor who only engages at filing time has already missed the window to help you with most of them.

2. They Have Never Discussed Your Entity Structure

If you have operated the same LLC or sole proprietorship for years as your income has grown substantially, and your CPA has never proactively raised whether an S-Corp election or a different structure would save you money, that is a significant gap. See S-Corp vs C-Corp: which saves more in taxes for what this conversation should actually cover.

3. Your Reasonable Compensation Was Never Analyzed

If you are an S-Corp owner and your salary figure was picked once, years ago, without any documented benchmarking or annual review, you are carrying unnecessary audit risk, unnecessary payroll tax, or both. See how much to pay yourself as an S-Corp owner for what a proper analysis looks like.

4. You Have Never Heard of Cost Segregation

If you own commercial real estate or rental property and your accountant has never mentioned a cost segregation study, you are very likely depreciating your building on the slowest possible schedule the law allows, leaving significant deductions unclaimed. This single gap, on its own, is often reason enough to seek a second opinion.

5. Your Retirement Plan Options Stop at a Basic SEP-IRA

A SEP-IRA is a fine starting point, but for owners with strong, consistent profitability, it caps out at a fraction of what a properly designed cash balance plan could allow. If a defined benefit plan has never come up in conversation despite your income clearly supporting one, your advisor is not exploring the full range of options available to you. See tax strategies for business owners making over $1 million for what this can look like at higher income levels.

6. They Cannot Explain Why They Recommend Something

A qualified advisor should be able to explain the specific IRC section, the math behind the projected savings, and the tradeoffs of any strategy they suggest. If every answer is a vague reassurance rather than a clear explanation, you have no way to evaluate whether the advice is actually sound, or whether it is being applied consistently across your full financial picture.

7. You Feel Like You Are Teaching Them About Your Industry

Certain professions carry industry-specific opportunities: the FICA tip credit for restaurants, unique buildout considerations for medical and dental practices, vehicle strategies for contractors. If you find yourself explaining your own industry's tax nuances to your accountant rather than the other way around, it is a sign they may not have the specialized experience your situation calls for. See our guides for restaurant owners and construction company owners as examples of how industry-specific this planning really is.

What a Good Transition Looks Like

Switching advisors does not require amending every prior return, though a review of the last three open tax years is worthwhile to identify any missed opportunities that can still be corrected. A new advisor should be able to request prior returns and financial statements directly, review your entity structure and compensation history, and present a concrete plan, with projected dollar savings, before you commit to anything long-term.

The Cost of Staying Too Long

Every year spent with an advisor who only prepares your return, rather than actively planning around it, is a year of savings permanently lost. Unlike a missed deduction that can sometimes be recovered through an amended return, an entity structure that was never optimized, or a retirement plan contribution window that closed, cannot be recovered after the fact. See why business owners overpay taxes every year for the fuller picture of what proactive planning actually changes.

Trust Your Instincts, But Verify With Numbers

A nagging feeling that you are overpaying is worth investigating, but the decision to switch advisors should ultimately rest on a concrete comparison: what your current advisor has actually implemented for you versus what a second opinion identifies as available and unclaimed. Request a complimentary review from a prospective new advisor before committing to a switch, and evaluate whether the specific, quantified opportunities they identify are credible and well-explained.

Making the Switch Without Disruption

A well-managed transition includes a clean handoff of prior-year records, a review of open tax years for any missed opportunities worth correcting, and a documented plan for the current year before the old relationship formally ends. Most business owners who make this switch describe the biggest surprise as realizing how much more responsive and proactive a specialized advisor relationship can be compared to what they had grown used to.
