How to Switch Tax Accountants: A Clean Handover

Learning how to switch tax accountants comes down to one idea: a clean handover.

At All Digital Tax, we see the same pattern each year. Business owners stay with an accountant who misses deadlines or never answers email because switching feels risky.

Below, we walk through when to switch, how to choose a replacement, how to give notice, the documents to gather, and the mistakes that cause the most trouble.

A common mistake is waiting until a deadline is close. Start now, while there is room to move.

What You’ll Need Before You Start

Gather four things before you contact anyone new:

  • A copy of your last filed tax return
  • Your most recent financial statements
  • A list of open items, such as unfiled returns or pending questions
  • Your engagement letter with the current firm

That last item matters more than people expect. The engagement letter spells out the terms you agreed to, including how the relationship ends.

Pro Tip
Check your engagement letter for a notice period before you send anything. Some firms ask for written notice weeks ahead. Knowing the term first keeps you from creating a gap in coverage.

Step 1: Confirm the Right Time to Make the Move

The best time to switch is after your current year’s return is filed and accepted. That timing avoids two preparers touching the same return.

Some situations push the move earlier:

  • Repeated missed deadlines
  • Emails that go unanswered for weeks
  • Surprise balances you were never warned about
  • Advice that never addresses your actual business

If any of those sound familiar, the timing question answers itself.

One note on switching mid-year. It is allowed. You just need a clear handover so nothing gets filed twice or missed.

Step 2: Compare and Vet Replacement Accountants

Vet a replacement the way you would hire anyone who handles your money. Ask direct questions and listen for direct answers.

What to compare:

What to Check Why It Matters Red Flag
Response time Shows how the firm treats clients No reply within a week
Year-round service Proactive planning vs. once-a-year filing Tax-season-only contact
Your industry fit Crypto, consulting, or S Corp experience Vague answers on your niche
Written communication Clear record of every decision Phone-only promises
Handover support They help you get records moved “Just send us everything”

Ask each firm how they handle your specific income streams. A firm that works with service businesses and digital asset investors will ask sharper questions than one that files returns for everyone.

Watch Out
Do not hire on price alone. A low fee often means no planning during the year, and missed planning can cost more than the fee you saved.

How to Tell Your Accountant You Are Leaving

Tell your current accountant in writing, by email, and keep it short and neutral. You do not owe a long explanation.

A simple message works:

Subject: Transition of my account

Hello [Name],

I am writing to let you know I will be moving my account to a new preparer for the coming year. Please send my records and any work in progress to me at [email] by [date].

Thank you for your work on my account.

[Your name]

Three rules for this message:

  • Keep it factual. No complaints, no blame.
  • Ask for your records in the same email.
  • Set a date, but leave reasonable room.

Most preparers respond professionally. They hand over records because professional standards expect it.

Documents to Transfer to a New Tax Accountant

Most guides hand you a vague list. A working inventory is more specific, because the records that cause the most trouble are the ones nobody thinks to ask for. Use the four groups below as a checklist and request everything at once.

Tax filings

  • Filed federal and state returns, last three years
  • Any extensions filed and the date each was accepted
  • Notices received and the responses sent
  • Estimated tax payment records and confirmation numbers
  • State registration numbers and any local filings

Financial records

  • General ledger and trial balance
  • Bank and credit card statements
  • Payroll records, contractor filings, and year-end forms
  • Fixed asset register and depreciation schedules
  • Basis worksheets for any assets sold or acquired
  • Carryforward schedules: net operating losses, capital losses, and credits

Business documents

  • Entity formation papers and any amendments
  • Prior elections and agreements (for example, an S corporation election or an accounting method election)
  • Ownership or shareholder records
  • Loan documents and amortization schedules

Your own files

  • Copies of anything you sent them
  • Notes from past planning conversations
  • A short written summary of open questions
Pro Tip
Ask for the depreciation schedules and carryforward worksheets by name. They are the two items most often left out of a records release, and rebuilding them later takes far longer than requesting them now.

How the Records Actually Move

Two mechanisms do the work. First, a signed authorization (IRS Form 8821 or Form 2848) lets your new preparer pull your IRS transcripts directly, which shows what was filed and paid without waiting on the old firm. Second, a written records request to the outgoing preparer covers the working papers, schedules, and notes that never get filed anywhere.

Send both requests the same week. If you only do one, you will end up waiting on the slower path.

What the Outgoing Preparer Must and Must Not Do

Under the IRS rules that govern tax practitioners (Circular 230), a preparer must promptly return the records you need to meet your federal tax obligations when you ask, even if there is a fee dispute; they may keep copies. What they can generally hold back: their own internal workpapers, and in some cases returns or documents they prepared for you while the fee for that work is unpaid, though they still have to let you review and copy what you need. That is why the engagement letter matters. Read the termination and records clauses before you send notice.

Key Takeaway
You own your records. A preparer holds them for you, not from you. If a request for your own files goes unanswered, send a second written request, keep a copy, and note the date. A short paper trail resolves most delays.

A Document-Transfer Inventory You Can Reuse

Keep this list in a single document and check items off as they arrive. Mark each item with the date requested and the date received. When the new preparer confirms the handover, you have a complete record of what moved and when, which is exactly what you want if a question comes up months later.

Switching Tax Accountants During Tax Season

Switching during tax season is possible, but it needs a tighter plan. The risk is not the switch itself. The risk is two preparers working the same return, or a deadline passing while responsibility is unclear.

Decide Who Owns the Filing Before Anything Else

Pick one preparer to own the current year’s return and put it in writing. The cleanest rule: whoever has already started the return finishes it. Move everything else, next year’s engagement, bookkeeping, planning, to the new preparer after the return is filed and accepted.

If the current return has not been started, the new preparer can take it, but only after the authorization is in place so they can pull prior filings and confirm what has already been submitted.

Work Through This Sequence

  1. Confirm in writing whether the current return is started, filed, or extended.
  2. Have the new preparer submit the authorization so they can access prior filings.
  3. Get a written status note from the old firm: what is done, what is open, what is waiting on you.
  4. Name one owner for the filing in a short email to both preparers.
  5. Confirm the deadline and, if needed, who files the extension.

When a Deadline Is Close

If the filing deadline is near and the return is not close to done, an extension is often the calmer path. The extension moves the filing date, not the payment date, any tax owed is still due by the original deadline, so estimate and pay what you can to avoid interest and penalties. The IRS makes the same point: an extension to file is not an extension to pay. Decide who files the extension before you switch, and get that decision in writing.

If a Return Is Already in Progress

Let the current preparer finish it. Moving a half-finished return to a new preparer usually costs more time than it saves, because the new preparer has to reconstruct what was already done. Finish, file, then move.

If a Notice or Examination Is Open

An open notice or examination changes the math. The preparer who handled the year in question usually has the records and the context, so keeping them on that matter until it closes is often the lower-risk choice. You can still move your ongoing bookkeeping and next year’s filing to the new preparer in parallel. Get the responsibility split in writing so nothing falls between the two.

Never let both firms file. One return, one owner. Two filings on the same year create amended returns, duplicate submissions, and a paper trail that takes months to unwind.

What to Put in the Handover Email

Keep it short and factual. State the year in question, who owns the filing, the deadline, and what you need from each side. No complaints, no blame. A written record protects everyone and makes the handover faster.

How Long Does It Take to Change Accountants?

Changing accountants usually takes two to four weeks from first contact to full handover. The records transfer is the slow part, not the hiring.

A realistic timeline:

  • Week 1: Vet and choose the new preparer
  • Week 1-2: Send written notice to the old firm
  • Week 2-3: Records arrive and get organized
  • Week 3-4: New preparer reviews and confirms the handover

Delays come from three places: a slow records release, missing documents, and unclear ownership of work in progress. Settle all three up front and the timeline holds.

Common Mistakes to Avoid When You Switch Tax Accountants

Most problems in a switch come from moving too fast or too quietly. Avoid these:

  • Leaving before the new preparer is confirmed. You can end up with no one covering a deadline.
  • Skipping the written notice. A verbal goodbye leaves no record.
  • Forgetting work in progress. Ask who owns unfinished work and who bills for it.
  • Not checking the engagement letter. Notice periods and file terms live there.
  • Assuming records transfer themselves. You have to ask, in writing.
  • Letting two firms file. One return, one owner.

Get these right and the switch stays boring. Boring is the goal.


A switch goes wrong when the handover is rushed, not when the decision is made. All Digital Tax handles this transition with a written process from day one, so nothing gets lost between preparers. Our year-round tax strategy and bookkeeping keep your books and filings aligned all year, and our crypto and digital asset reporting covers the income streams most firms skip.

Frequently Asked Questions

How do you tell your accountant you are leaving?

Send a short, professional message by email or through their client portal. Thank them for their work, state that you are moving on, and ask them to transfer your records to your new tax accountant. Put the request in writing so there is a clear record of the date. You do not owe a long explanation, and you can keep it to a few sentences.

When is the best time to switch tax accountants?

The calmest window is after your return is filed and before the next filing season begins. That gives the new accountant time to review your records and plan before deadlines arrive. If you need to move during filing season, do it early and confirm in writing who is responsible for the open return so nothing falls through.

Can I switch tax accountants during tax season?

Yes, though timing matters. If your return is not yet filed, agree in writing on who will file it and make sure the new accountant has the records needed to meet the deadline. If your return is already filed, the handover is simpler. If a filing is already late, address that first. Switching tax accountants during tax season works best when one side clearly owns each open item.

What should I look for in a new tax accountant?

Look for someone who works with your income types, whether that is business income, crypto activity, or multiple streams. Ask how they handle year-round questions, how they communicate, and what records they need from you. Request a written engagement letter that spells out the scope of work. A short review of your prior return can show whether they catch details your last provider missed.
