Switching accountants means ending your current accounting relationship, moving your financial records to a new provider, and updating access to your books, software, and tax filings.
Most of the process is simple. The part people often forget isn’t the paperwork with the old accountant. It’s what happens with the IRS afterward.
Have you been delaying a switch because you think it will be a huge disruption? The process usually takes a few weeks, not months. Good timing, complete records, and a smooth accounting data migration process can make the switch much easier.
What switching accountants actually involves
Switching accountants usually depends on the three steps.
First, your current accountant hands over the records. Then your new accountant reviews everything and takes over from there. Finally, you update any tax authorizations connected to your old accountant so they no longer have access or authority to act as your representative.
Most people worry about the first step. They’re afraid records will get lost or that the transfer will take forever.
In reality, your financial history already exists in your bank statements, accounting software, and filed tax returns. Hiring someone new doesn’t make that information disappear.
In our experience handling these transitions, delays usually happen on one side, not both, often because one firm doesn’t have a clear process for transferring the records.
Signs it’s actually time to switch accountants
Not every problem means you need a new accountant. These are the issues we hear most often when business owners are changing accountants:
You’re not getting straight answers: You ask a question and get a delay or silence instead of a clear explanation.
Your books are always late: If you’re seeing last month’s numbers in the middle of this month, you can’t use them to make timely decisions.
Everything is reactive, never proactive: Your accountant files what’s required but doesn’t point out risks or opportunities before deadlines arrive.
You don’t trust the numbers: If you’re constantly checking their work yourself, the relationship isn’t doing what it should.
Your business has grown beyond their setup: This doesn’t always mean the accountant is doing a bad job. Someone who was a great fit when you had $300K in revenue and one bank account may not have the right setup for a $3M business with payroll, multiple entities, or financing needs, the kind of extra work that shows up fast in accounting for tech startups after the first funding round.
If two or three of these are familiar, it may be time to start looking at other options rather than waiting for things to get worse.
When it’s not actually time to switch
Not every issue is a reason to switch accountants. If the issue was a one-time mistake your accountant owned and fixed, a difficult period during a genuinely busy season or a fee increase that still shows the value you’re getting, switching may cause more problems than it solves.
Look for a pattern, not one bad experience. A direct conversation about expectations can sometimes fix a problem much faster than a full transition.
How to change accountants, step by step
The process is simple when you handle each step in the right order.
| Step | What to do | Why it matters |
|---|---|---|
| 1. Line up your new accountant | Confirm they’ve accepted the engagement before giving notice to your old one | Avoids a gap where nobody is responsible for an upcoming deadline |
| 2. Notify your current accountant | A short and professional email with a clear end date | You don’t owe a detailed explanation, just clarity |
| 3. Request your records | Prior returns, financial statements, payroll records, software access | You’re entitled to your own data |
| 4. Transfer software and account access | Export or share your accounting file and update the logins | Prevents duplicate work and access disputes later |
| 5. Sign an engagement letter | Review scope, fees, and responsibilities with your new accountant | Protects both sides and sets expectations |
| 6. Update IRS authorizations | Review Form 2848, Form 8821, and responsible-party status | The step people often miss |
Once these steps are done, your new accountant can take over without unnecessary delays or confusion.

How long does switching accountants take?
For most small businesses, a switch takes about two to four weeks from the first conversation with the new accountant to a complete handoff.
If your books are already up to date and you respond quickly when documents are requested, it can happen faster, which is one of the main benefits of virtual bookkeeping, since everything is stored online instead of in paper files.
Some firms can send a proposal within a day or two and start onboarding within a week. The timeline gets longer when your books need cleanup. If your accounts haven’t been reconciled for several months or there’s a backlog of transactions, the cleanup may happen at the same time as the switch.
In other words, the transition itself usually isn’t the slow part. The condition of the books you’re handing over is.
Timing also matters. The easiest time to switch is usually after a quarter-end or year-end close rather than right in the middle of a tax deadline.
But don’t wait for the “perfect” time if your current accountant isn’t responding or your books are being neglected. A good new accountant can take over mid-cycle and work through anything that’s missing.
What records you’re actually entitled to
This is one of the biggest worries people have when switching accountants, but it’s usually less complicated than it seems.
Not everything in your old accountant’s files belongs to you in the same way.
Bank statements, invoices, receipts, and other documents you gave your accountant are your records. Keep copies of them.
Filed tax returns and financial statements that were prepared and delivered to you should also be part of your records.
Internal notes, drafts, and calculations your accountant created while preparing your returns may remain their property unless your agreement says something different.
The AICPA’s professional standards generally expect accountants to release records that clients are entitled to receive quickly, generally within 45 days after a request, depending on the circumstances and applicable requirements.
That’s useful to know if an old accountant is taking too long to respond. You’re not simply asking for a favor, you’re asking for something with a defined timeline behind it.
When requesting records, be specific about what you need instead of just asking for “everything.” Also keep copies of documents you already have. We’ve seen businesses switch accountants and only then realize they don’t have their own copy of last year’s return.
Transferring your accounting software and access
If your old accountant had access to QuickBooks, payroll systems, bank feeds, or other financial accounts, handle the transfer carefully. This matters even more if you’re switching to a professional virtual accountant who handles everything online.
- Export or share your accounting file instead of relying on your old accountant’s login staying active.
- Give your new accountant their own login rather than sharing old credentials. This is better for security and gives you a cleaner record of who accessed your books.
- Remove the old accountant’s access once the transfer is complete, including bank feeds and payroll systems.
- Check your chart of accounts and transaction history to make sure everything transferred properly. This is often where a new accountant finds cleanup work.
If you’re using QuickBooks, changing the primary accountant user is a built-in feature, so you usually don’t need IT support for it.
How to verify a new accountant’s credentials
Before you sign anything, confirm who you’re actually hiring. The word accountant by itself doesn’t tell you much about someone’s licensing or qualifications. CPA and Enrolled Agent (EA) are specific credentials with professional requirements behind them.
A few things to check:
- Ask if they’re a CPA, EA, or working under one. A firm can have bookkeepers and accountants who aren’t CPAs, but you should know who will handle each part of your work.
- Check CPA licensing where applicable. CPA licenses can be verified through your state’s board of accountancy.
- Ask about industry experience. A generalist accountant and one who works regularly with your industry will spot different issues in your books.
- Ask what they need before giving you a price. A good accountant will usually want to review your previous tax returns and financial statements before giving you a firm quote, because how much a bookkeeper costs per month usually depends on how much work you need.
This matters because you’re trusting someone with important financial information, often without being able to check every transaction yourself.
The changing accountants letter
If you’ve searched for a “changing accountants letter,” you’re looking for a short and professional notice telling your current accountant that you’re moving on.
A simple version can look like this:
This letter is to inform you that, effective [date], we will be moving our accounting services to a new provider. We’d appreciate your help transferring our financial records, including [specific documents], to our new accountant by [date]. Thank you for your work over the past [time period].
The IRS step you shouldn’t forget
Ending your relationship with your old accountant doesn’t automatically update who the IRS has on file as your authorized representative. This separates a clean switch from a messy one later.
There are two things you should check:
- Responsible party changes: If your accountant’s information was ever listed as your business’s responsible party with the IRS, Form 8822-B is used to update that information.
- Existing authorizations: A Power of Attorney (Form 2848) and tax information authorization (Form 8821) don’t automatically end when you stop working with an accountant. If your old accountant still has one on file, they may still be able to receive your tax information or act for you until the authorization is formally revoked or replaced.
Filing a new Form 2848 generally revokes an earlier one for the same matter, but Form 8821 follows a broader rule. It can revoke all prior authorizations on file unless you specifically check the box to retain an earlier one. This step isn’t difficult to fix. Your new accountant can usually handle the forms during onboarding. But if nobody checks it, you could discover months later that your old accountant still has access or authorization that should have been removed.
Common mistakes when changing accountants
These mistakes are easy to avoid if you plan the switch before ending the old accountant relationship.
- Waiting until books are “perfect” to switch: Most accountants are used to working with books that need some cleanup. Waiting only delays getting the help you need.
- Not backing up your own records before losing system access: Download the records you need before access to your old systems is removed.
- Missing compliance deadlines while changing accountants: Payroll and sales tax deadlines don’t stop just because you’re changing accountants.
- Assuming the switch itself increases audit risk: It doesn’t. The IRS doesn’t flag a return because you have a new preparer. The real risk comes from inconsistent reporting or missing information when the switch isn’t handled properly.
- Sharing login credentials instead of giving separate access: This creates a security problem and makes it harder to track who accessed your financial systems.
A smooth switch depends on keeping your records, deadlines, and account access organized from the start.
Where this leaves you
Switching accountants is usually less disruptive than people expect. The real problem isn’t the switch itself. It’s the details that get missed, especially the IRS authorization step and making sure you have copies of your financial records.

FAQs
Is it hard to change accountants?
Not usually. The basic steps, including transferring records, signing a new engagement letter, and updating access, are simple. Choosing the right new accountant takes longer than the switch itself.
Can I switch tax preparers if I'm mid-filing?
Yes, although it's cleaner to switch before your next return is prepared rather than in the middle of one. If your current preparer has already done most of the work, it may be simpler to let them finish that return and switch for the next one.
How do I change accountants without losing my financial history?
Ask for copies of your previous tax returns, financial statements, and supporting schedules before you lose access to your old accountant's systems. As the client, you're generally entitled to important records related to your work.
Do I need to tell the IRS I've changed accountants?
Sometimes. If your old accountant had a Power of Attorney or tax information authorization on file, or was listed as your responsible party, those records may need to be updated separately. They don't change automatically just because you stop working together.
