How to Fire Your Accountant: Termination Letter and IRS Revocations

To fire your accountant, send a written termination letter by certified mail that sets an end date, requests your records back, and asks for a final invoice; then revoke any IRS authorizations they hold and remove their access to your accounting software and payroll systems the same day. Done in that order, the handoff takes a few weeks and leaves no loose ends. Skip a step and your former accountant can keep viewing your tax account, billing you, or holding files you need for your next return.

Read the Engagement Letter Before You Do Anything

Pull out the agreement you signed when you hired the firm. Most accounting engagements begin with a written letter covering scope, fees, and how either side ends the relationship. Many include a notice period, often 30 days, and some require written notice sent to a specific address or contact. Miss the termination clause and you can end up owing fees for a notice period you didn’t honor, or facing pushback when you ask for your files.

Some firms use “evergreen” engagement letters that renew automatically every year unless one side formally ends them. If yours is one of these, the relationship continues indefinitely until you take action. Look specifically for language on early termination fees, final billing for work in progress, and the firm’s deadline to return your files. Those details set the timeline in your termination letter.

Time the Switch Carefully

The worst moment to fire your accountant is mid-tax-season with a filing deadline a few weeks out. If they’re halfway through your return, finding a replacement who can pick up unfinished work under pressure is difficult and expensive. The smoothest window is right after your annual returns are filed and any extensions are resolved, generally between June and November for most individual and business filers.

If you can’t wait, at least confirm no immediate deadlines are at risk. For 2025 individual returns, the standard filing deadline is April 15, 2026, and filing Form 4868 gives you an automatic six-month extension to October 15.¹ If you make quarterly estimated payments, verify the next one is scheduled or paid before you cut ties. The IRS estimated tax underpayment penalty generally cannot be waived for reasonable cause, so a change of accountants is not an excuse the agency will accept.²

What to Put in the Termination Letter

A workable termination notice covers a short list of essentials:

Your legal name and address, and the accountant’s name, firm, and address, so the notice reaches the right desk.
A specific effective termination date. After that date, the firm has no authority to file returns, make payments, or contact the IRS on your behalf.
An explicit list of records you want back, itemized by document type and year rather than a blanket request for “everything.”
The delivery format you want (electronic or paper) and a deadline for receiving the files.
A request for a final itemized invoice covering any outstanding work, so no surprise charges appear later.
The name and contact information for your replacement accountant, so the firm knows where to direct transition questions.

Which Records You Can Actually Demand

This is where most disputes happen, and the rules are not as simple as “it’s all my stuff.” The AICPA Code of Professional Conduct sorts records into three categories with different ownership rules.

Client-provided records are documents you originally gave the accountant: bank statements, receipts, prior-year returns. The accountant must return these on request and cannot hold them for unpaid fees.³

Member-prepared records are items the accountant created that complete your financial picture, like adjusted trial balances or depreciation schedules. You can request these, but the accountant can withhold them if you owe fees specifically for the work that produced them.³

Working papers cover audit programs, internal analysis notes, and sampling results the accountant created for their own use. These belong to the firm, and under AICPA rules the accountant has no obligation to hand them over.³ State law sometimes overrides this, so your replacement accountant may be able to negotiate access even when the AICPA rules do not require it.

In your letter, ask for everything, listed by specific document type. If the accountant pushes back on certain items, you will at least know which category the dispute falls into and whether they have a legitimate basis to withhold.

How to Send It

Send the letter by certified mail with return receipt requested. The receipt gives you a signed, dated record proving the firm got the notice, which matters if the accountant later claims otherwise or keeps billing past the termination date. Keep the receipt with your records indefinitely.

If the firm uses a secure client portal with digital tracking, uploading the letter there creates a second layer of documentation. Either way, keep a copy of the letter itself. Follow up if you have not received acknowledgment within about a week. The actual transfer of records often takes a few weeks depending on volume, but do not let silence stretch on without a response.

Revoke Any IRS Authorizations

Sending a termination letter to your accountant does not automatically strip their access at the IRS. If your accountant holds a Power of Attorney (Form 2848) or a Tax Information Authorization (Form 8821), they can still view your tax information, and in the case of a POA act on your behalf, until you formally revoke those authorizations.

Revoking Form 2848

If you have a copy of the Form 2848 you previously filed, write “REVOKE” across the top of the first page, sign and date it below that annotation, and mail or fax the marked-up form to the IRS using the Where To File chart in the form instructions. If you do not have a copy, send the IRS a written statement that says the authority is revoked, lists the tax matters and years covered, and includes the name and address of the representative. Sign and date the statement. To revoke authority for all years, write “revoke all years/periods” rather than listing them individually.⁴

One shortcut: if your new accountant files a new Form 2848 covering the same tax matters, the IRS will generally revoke the old one automatically when it records the new authorization.⁴ Relying on this alone leaves a gap between when you fire the old accountant and when the new one files their paperwork. Explicitly revoking first is safer.

Revoking Form 8821

The process for Form 8821 mirrors Form 2848. Write “REVOKE” across the top, sign and date below, and submit it to the IRS.⁵ A POA lets someone act on your behalf; a Tax Information Authorization only lets them view your records. Lower level of access, but still not something you want a former accountant to retain.

Third-Party Designee on Your Return

If you checked the “Third Party Designee” box on your most recent Form 1040, that authorization expires automatically one year from the return’s due date.⁶ No separate revocation is required, but note it may still be active for several months after you have ended the relationship.

Cut Off Digital Access the Same Day

IRS forms are not the only access point. If your accountant had login credentials or administrative access to any of the following, revoke them the same day you send the termination letter:

Cloud accounting software. In QuickBooks Online, go to Settings, select Manage Users, find the accountant under the Accountants tab, and delete them. The removal is immediate. Xero, FreshBooks, and similar platforms have comparable steps in user management.⁷
Bank and credit card feeds. If your accountant pulled bank feeds through your accounting software, removing their user access typically disconnects their view. Verify separately with your bank if you gave the accountant direct online banking credentials.
Payroll platforms. If the accountant ran payroll through ADP, Gusto, Paychex, or similar, contact the provider to transfer administrative control before removing the accountant’s access. Removing them first can freeze your payroll runs.
Document storage. Revoke or re-permission any shared drives, Dropbox folders, or Google Drive access.

Digital access does not know about your termination letter. Until you manually cut it, the accountant can still view and sometimes modify your financial data.

Keep Tax Deadlines on Track

The IRS does not care that you are between accountants. Filing deadlines and payment obligations do not pause during a transition, and the consequences land on you.

If a filing deadline is approaching and your new accountant does not yet have the records to prepare a complete return, file for an extension. Form 4868 provides an automatic six-month extension for individual returns.¹ An extension gives you more time to file, not more time to pay. Estimate your liability and pay by the original deadline to avoid interest and penalties.

The IRS is explicit that relying on a tax professional does not qualify as reasonable cause for late filing or payment. But if your former accountant’s refusal to return records leaves you unable to file, the IRS does recognize inability to obtain records as a possible basis for penalty abatement.⁸ Document everything: copies of your records requests, dates sent, delivery confirmations, and any responses. That paper trail is what you would submit to the IRS if you need to request relief.

While you wait, your new accountant can request IRS transcripts covering wage and income data, return information, and account balances for prior years. Transcripts do not replace everything in your files, but they are often enough to keep things moving.

If Your Former Accountant Refuses to Cooperate

Most transitions go smoothly. When one does not, you have options beyond sending increasingly frustrated emails.

File a complaint with your state board of accountancy. Every state has a licensing board that regulates CPAs and can investigate complaints about professional misconduct, including failing to return client records. Filing is typically free, and the board can discipline licensees through sanctions ranging from a letter of concern to suspension or revocation. Often, simply filing the complaint gets the records released, because most accountants take board inquiries seriously.

Report the issue to the IRS if the accountant is a tax return preparer who engaged in misconduct beyond being uncooperative. You can file a complaint through the IRS online complaint process.⁹ This route fits situations involving fraud, unauthorized filings, or misuse of your tax information rather than a simple records dispute.

And give your new accountant written authorization to contact the former firm directly. Include that authorization in your termination letter so the old firm knows to cooperate. If the former accountant limits or refuses communication with your new representative, that is worth noting, and worth flagging to whoever reviews any complaint you later file.
