Switching accountants feels harder than it is. Business owners stay with underperforming CPA firms for years because the transition seems disruptive, the timing never feels right, and the prospect of recreating institutional knowledge feels daunting.
In practice, a well-managed transition takes two to four weeks and creates no gaps in compliance, reporting, or financial visibility. The key is knowing what to collect, when to time the move, and what your new firm needs to hit the ground running.
Signs It Is Time to Make a Change
Certain patterns indicate that the relationship has run its course. Your CPA is reactive, not proactive. They file returns accurately but never suggest ways to reduce your tax liability. Communication is slow, unpredictable, or one-directional. You feel like one of hundreds of clients rather than a priority. The firm does not offer services you have grown into needing, such as fractional CFO support, payroll, or multi-state compliance. Your financial statements arrive late, and you cannot get clear answers about your numbers when you need them. Fees increase without corresponding improvements in service or scope.
None of these issues alone may be decisive. But if three or more describe your experience, the cost of staying likely exceeds the cost of switching.
The Transition Checklist
Documents to Request from Your Current Firm
Before formally ending the engagement, request copies of at least three years of filed federal and state tax returns (personal and business), financial statements (income statement, balance sheet, cash flow), fixed asset and depreciation schedules, payroll records and filings (941s, W-2s, state filings), sales tax returns, any unfiled or in-progress returns, and the engagement letter and any outstanding invoices.
These records belong to you. Your current firm is obligated to provide them regardless of the reason for the transition.
Access and Platform Handoff
If your books are maintained in a cloud platform (QuickBooks Online, Xero, FreshBooks), ensure that you have administrator access and can invite your new firm. If your current firm holds admin access and you do not, request that they transfer ownership before the relationship ends.
For payroll systems, ensure your new firm can access historical payroll data and that no interruption occurs in deposit scheduling.
IRS and State Authorization
Your new CPA will file Form 2848 (Power of Attorney) or Form 8821 (Tax Information Authorization) to access your IRS account and obtain transcripts. This allows them to review prior-year filings, verify payments, and identify any outstanding IRS notices.
Similar authorizations are filed with state tax agencies as applicable.

Best Timing for the Switch
The ideal transition window is between May and September. By May, prior-year returns are typically filed (or extended). September gives enough runway for the new firm to take over year-end planning and prepare for the following tax season.
Switching during tax season (January through April) is possible but introduces time pressure. If you are dissatisfied during tax season, consider filing an extension with your current firm and then transitioning during the summer.
What Your New CPA Needs on Day One
The onboarding process is smoother when the new firm receives access to your cloud accounting platform, copies of all prior-year returns and financial statements, a summary of your entity structure (entities, ownership, EINs), current payroll setup and employee/contractor details, any open IRS or state notices, and your business goals and pain points that prompted the switch.
The last item matters more than most clients realize. A good CPA firm will structure their service around what was missing before, not just replicate the prior firm's approach.
How to Handle the Conversation with Your Current Firm
Keep it professional and brief. You are not obligated to explain your reasons in detail. A simple statement that you have decided to move your accounting to another firm and a request for the documents listed above is sufficient. Most firms process transitions regularly and will cooperate without difficulty.
If outstanding fees are owed, resolve them before requesting records. While firms cannot legally withhold your tax returns over unpaid fees in most states, unresolved billing disputes can slow the process.
What a Good Onboarding Process Looks Like
A well-structured onboarding by your new CPA firm includes an initial meeting to understand your business, goals, and what was missing from the prior relationship. A review of prior-year returns for accuracy and missed opportunities. Assessment of current books for cleanliness and completeness. Setup of IRS and state power of attorney. A clear engagement letter with defined scope, pricing, and communication expectations.
TYM Consulting follows a structured onboarding process for every new client, including a prior-year return review that frequently identifies missed deductions, structural improvements, and compliance items that were overlooked.
