Switching accountants is one of those decisions that feels much harder before you do it than during. Business owners delay the change for months, sometimes years, because they assume the process will be disruptive, that they will lose access to historic records, or that the current accountant will refuse to cooperate.
In practice, switching is well-established, professionally regulated, and almost always smoother than expected. The new accountant manages the handover, professional clearance follows a predictable process, and most businesses are fully transitioned within four weeks with no gap in compliance.
This guide walks through the clearest signs it might be time to change accountants, what good looks like in a new accountant, how the switching process actually works for a sole trader or a limited company, and how to avoid the common mistakes that slow it down. It applies whether you handle your own bookkeeping in Xero or whether your existing firm runs it for you, and the goal in either case is the same: a seamless transition that keeps your business compliant from day one.
Why do Irish businesses switch accountants?
Switching accountants is normal, not drama. Many growing Irish businesses change adviser at least once every five years for entirely positive reasons: the business has outgrown the old firm, the founder needs a more digital approach, or a new growth phase needs proactive tax planning the previous accountant could not provide.
The triggers we see most often when a new client comes to us are:
- Poor or slow communication. Emails take a week to get a reply. The same question gets escalated three times before it lands with someone who can answer it
- Missed tax deadlines. VAT, PAYE, the CT1 return, the annual return to the CRO, accounts sign-off. Any pattern of missed filings is a serious red flag
- Hidden costs and unclear pricing. The agreed fee at the start of the year becomes three different invoices for “extra work” by year-end
- Lack of industry expertise. The accountant has never worked with a business like yours and gives generic advice that does not apply
- Inadequate tax planning. You only hear from the firm at year-end, never proactively, and tax bills land as surprises rather than planned outcomes
- Limited capacity to support business growth. The firm cannot handle scaling payroll, multi-entity structures, R&D claims, or international VAT
- Outdated technology. No cloud software, no client portal, paper records returned in a folder once a year
- Loss of trust after an error or audit. A material mistake, a Revenue investigation, or a director’s penalty that should have been avoided
One or two of these can have an innocent explanation. Three or more usually means it is time to switch.
What does “good” look like in a new accountant?
Before you start looking, write down what good looks like for your business. The benchmarks we share with clients thinking about a change:
- Replies to emails within one working day, with named individuals you can speak to directly
- Proactive deadline reminders and a calendar of what is due when
- A transparent fixed monthly fee covering an agreed scope, with no hidden costs
- Quarterly check-ins on the numbers, not just year-end conversations
- Tax planning conversations during the year while there is still time to act
- Modern cloud accounting software (Xero is the most common in Irish small business) with shared access so you and the firm see the same data
- Genuine industry expertise relevant to your sector and size
- The capacity to grow with you, including payroll, management accounts, advisory, and audit if needed
If your current firm does not deliver on this list, it is almost certainly time to make a change.
Is it difficult to switch accountants in Ireland?
No. The switching process is well-defined and your new accountant takes most of the work off your hands. From the client’s perspective, the practical effort is usually one signed engagement letter, one email to the old firm telling them you are moving, and a couple of access permissions on accounting software. The new accountant handles professional clearance, requests the working papers, and notifies Revenue and the CRO where they act as agent for filings.
Most transitions take two to four weeks from the day the engagement letter is signed. The work is faster when your records are organised, fees with the old firm are up to date, and there is no immediate filing deadline.
Can I legally change my accountant, and does the previous accountant have to cooperate?
Yes. You can change your accountancy adviser at any time, subject to any notice period in your existing engagement letter (typically 30 days). The professional bodies (Chartered Accountants Ireland, ACCA, CPA Ireland) all have ethical rules requiring the outgoing accountant to cooperate with a reasonable handover request from a new accountant. Standard exceptions apply: an outgoing firm can withhold records under a valid lien if there are unpaid fees, and there are some legal records the new firm may need to obtain directly from Revenue rather than from the previous accountant.
The professional clearance process is the formal mechanism. Your new accountant writes to the previous one to:
- Notify them of the change and request any professional reasons not to act
- Request a handover of working papers, tax computations, and any draft accounts in progress
- Confirm the position on tax registrations, CRO filings, and any open Revenue queries
The outgoing firm typically responds within 14 days. Keep your own communication factual and calm. A professional outgoing accountant will be helpful even if the relationship has been strained; antagonism on either side only slows the process down.
How do you switch accountants step-by-step?
The cleanest path follows these eight steps in order.
- Decide what you need. Document the services you require, the cadence you want, and what good looks like for you. Use the list above as a starting point
- Shortlist three potential firms. Use referrals from other business owners, the professional body directories, and the Xero or QuickBooks partner pages for firms with software expertise
- Have a discovery call with each. Ask about the team, the fee structure, the software, the industries they specialise in, and how they handle tax planning during the year
- Choose the new accountant and sign the engagement letter. Make sure the letter clearly lists what is included and what is not. Set a start date that avoids landing in the middle of a tax deadline
- Notify the previous accountant. A short, polite email is enough. Mention the date the new firm is taking over and confirm any outstanding fees
- Let the new accountant handle professional clearance. They will write to the old firm requesting clearance and the handover of working papers
- Settle any outstanding fees with the previous accountant. Unresolved fees are the single most common reason for a delayed handover
- Update Revenue and the CRO. The new accountant will be appointed as agent on ROS and Companies Office filings. You may need to authorise the new agent through your ROS digital certificate
That is the entire process. Most business owners report later that the change was significantly easier than they imagined.
When is the right time to switch?
Timing matters less than people think. The right time is usually “now”, with two practical caveats: avoid switching in the two weeks before a major filing deadline, and avoid switching in the middle of a Revenue audit unless the relationship is actively damaging your case.
The most popular switching points in the Irish accountancy calendar are:
- Just after a year-end has been signed off and filed, so the new accountant takes over a clean slate
- At the start of the new tax year (1 January) for sole traders
- Three months before the company year-end, giving the new firm time to prepare for the year-end work
- Immediately after a poor experience that genuinely matters: a missed filing, a Revenue penalty, a bad audit, or a serious communication breakdown
If your current accountant is causing real risk (missed deadlines, untreated tax issues, no proactive advice during scaling), do not wait for a calendar milestone. The cost of one more bad month is usually higher than the cost of changing now.
What can go wrong, and how to avoid it?
The vast majority of accountant switches go smoothly. The handful that do not usually share the same root causes:
| Common problem | How to avoid it |
| Outstanding fees with the old accountant | Settle all outstanding invoices before the handover starts. Unresolved fees can hold up the working papers |
| Lost access to historic records | Download backups of Xero, QuickBooks, or any cloud-hosted records before formally ending the engagement |
| Filing deadline missed in the gap | Agree the start date with the new firm and make sure the old firm finishes any work due within the next month |
| Confusion about who is the active Revenue agent | Confirm the agent change on ROS as soon as the new engagement starts, so Revenue correspondence flows to the right place |
| Scope ambiguity in the new engagement | Read the new engagement letter carefully. Make sure it lists exactly what is and is not included in the monthly fee |
None of these are common, and each is easy to prevent with a little planning.
The cost of not switching
Most business owners we meet who eventually switch to a digital, proactive firm have been paying twice for accountancy for years without realising it. They pay the old firm their fee, and they pay again in time wasted chasing, in missed reliefs, in late-filing penalties, in compounding stress, and in business decisions made without proper financial information. The total cost of an underperforming accountant relationship for a growing SME can easily run to €10,000 to €30,000 a year in invisible value loss, on top of the fees actually paid.
Switching takes a few hours of attention and a couple of weeks of elapsed time. It is one of the highest-leverage things a business owner can do if the current relationship is not working.

Frequently asked questions about switching accountants in Ireland
How long does it take to switch accountants?
Most transitions complete within two to four weeks of signing the engagement letter with the new firm. Professional clearance typically takes 7 to 14 days, and the handover of working papers another week. Software migrations (for example moving from Sage Desktop to Xero) can extend this slightly, but in most cases the new firm has full control within a calendar month.
Will my old accountant find out before I tell them?
No. The professional clearance process only starts after you have signed an engagement letter with the new firm. There is no early notification to the outgoing accountant. Most business owners prefer to send a brief courtesy email themselves once the new engagement is signed, but this is your decision.
Do I have to pay the old accountant before switching?
You should settle any outstanding fees. The outgoing accountant has a right of lien over working papers in some circumstances, which can hold up the handover if fees are unpaid. Paying outstanding invoices in good faith almost always smooths the transition, even if you feel the work delivered did not justify them. Disputed fees can be addressed separately afterward through the professional body’s complaints procedure if necessary.
What happens to my filings during the switch?
Nothing should fall between the cracks if the handover is planned. The new accountant takes over the open work, files any returns due, and notifies Revenue of the change of agent. Avoid switching in the two weeks immediately before a filing deadline; outside of that, the transition has no impact on compliance.
Can I switch accountants if I’m in the middle of a Revenue audit?
Yes, although it adds complexity. The new firm will need full briefing on the audit position before they can take over. If the current relationship is contributing to a poor audit outcome, switching can be the right call; if the audit is purely procedural, it is usually easier to wait until it concludes. Speak to both firms before deciding.
