The start of a new year is when many business owners realize something isn’t working with their current accounting relationship. Maybe tax season felt reactive instead of planned. Maybe communication was slow, questions went unanswered, or the final tax bill was higher than expected. January and early February are also the best time to make a change, but switching tax advisors is not something you want to do blindly. Knowing what to expect and how to transition correctly can prevent delays, duplicate work, and unnecessary stress.

A well-timed switch can actually improve tax preparation, bookkeeping clarity, and long-term tax planning if it’s handled thoughtfully.

Why the Beginning of the Year Is the Best Time to Switch

Changing tax advisors mid-year is possible, but the start of the year offers a natural reset. Most of the prior year’s activity is complete, and planning for the new year has not yet been finalized. This gives your new tax advisor the opportunity to review what happened last year and influence decisions going forward.

Early-year transitions allow time to:

• Review the prior year’s tax return and filings
  
• Identify missed deductions or planning opportunities
  
• Clean up bookkeeping before tax preparation begins
  
• Set expectations for communication, timelines, and strategy
  
• Implement year-round tax planning instead of last-minute filing
  

Waiting until March or April often limits what can realistically be improved for the current filing season.

What to Gather Before You Make the Move

Switching tax advisors goes more smoothly when you come prepared. While your new advisor can help retrieve information, having key documents ready speeds up onboarding and reduces back-and-forth.

At a minimum, you should expect to provide:

• Prior-year individual and business tax returns
  
• Current-year bookkeeping files or access to accounting software
  
• Payroll reports and prior-year W-2 and 1099 filings
  
• Entity formation documents and ownership details
  
• Any IRS notices or correspondence received
  

Having this information upfront allows your new tax advisor to assess risk areas, filing requirements, and planning opportunities early in the process.

What Happens to Your Old Records and Files

One common concern is whether you “lose” anything by switching. In most cases, you do not. Tax returns belong to you, and bookkeeping data typically resides in your accounting software, not with the prior firm.

However, there may be limitations:

• Some firms do not release internal workpapers
  
• Engagement letters may restrict access to proprietary schedules
  
• Prior advisors are not obligated to provide planning memos or internal notes
  

This is normal and usually not a problem. A competent tax advisor can reconstruct what is needed from returns, financial statements, and source documents.

Understanding Timing and Filing Responsibility

Switching tax advisors does not automatically shift responsibility for deadlines. If the prior firm has already started work, it is important to clearly establish who is responsible for filing the return and communicating with the IRS.

Key questions to clarify include:

• Has the prior advisor already prepared or filed anything?
  
• Are extensions expected or already filed?
  
• Who will respond to IRS notices during the transition?
  
• What work is included versus billed separately?
  

Clear communication on these points prevents duplicate filings or missed deadlines.

Signs You’re Making the Switch for the Right Reasons

Not every frustration warrants a change, but some issues are strong indicators that a different approach may serve you better.

Common reasons business owners switch include:

• No proactive tax planning throughout the year
  
• Surprise tax bills with little explanation
  
• Difficulty getting timely answers to questions
  
• Lack of clarity around bookkeeping and reporting
  
• Feeling like a transaction rather than a client
  

A good tax advisor relationship should feel collaborative and forward-looking, not purely transactional.

What a Good Transition Should Feel Like

A well-handled transition is structured, calm, and organized. You should gain clarity, not confusion.

A strong onboarding process typically includes:

• A review of prior-year returns and current-year activity
  
• A discussion of business goals and growth plans
  
• Identification of immediate risks or opportunities
  
• Clear next steps for tax preparation and planning
  
• Defined communication expectations
  

If the transition feels rushed or disorganized, that is often a sign to slow down and ask more questions.

The Bigger Opportunity in Switching

Switching tax advisors is not just about fixing last year’s return. It is an opportunity to reset how taxes, bookkeeping, and planning support your business decisions. When done at the right time and for the right reasons, the change can lead to better cash flow planning, fewer surprises, and more confidence throughout the year.

The beginning of the year is the cleanest moment to make that move. With the right preparation and expectations, switching tax advisors can be a strategic step forward rather than a disruptive one.
