Can I Sue My Accountant for Negligence if They Made Mistakes on My Tax Returns or Accounts?
You can sue your accountant for negligence if their mistakes on your tax returns or accounts have caused you financial loss. Even if the error was unintentional, you have a potential claim if the accountant failed in their professional duty and you suffered penalties, interest, or extra tax as a direct result.
Many individuals and business owners are surprised to learn that, in the eyes of HMRC, they remain liable for penalties or additional tax bills even when their accountant has made a serious mistake. However, where you can prove your accountant breached their duty of care and this led straight to your loss, you may be able to claim compensation.
If you are unsure of your position or want to act before time limits expire, our professional negligence solicitors can assess your case promptly.
Can I Sue My Accountant for Negligence if They Made Mistakes on My Tax Returns or Accounts?
If your accountant has made errors in your tax returns or accounts which resulted in financial loss to you, you may have grounds for a professional negligence claim. To have a viable case, you must prove they did not act as a reasonably competent accountant would, and that their error directly caused your losses. Because legal time limits and the detail of each situation are critical, early guidance from a specialist is important.
If you believe your accountant’s mistake has cost you money, our solicitors can provide a confidential assessment of your potential claim.
What Counts as Accountant Negligence in Tax and Accounts Work?
Accountant negligence arises when the professional falls below accepted industry standards, resulting in loss to their client. Common examples include submitting incorrect tax returns, miscalculating liabilities, missing deadlines for submissions or payments, or failing to apply for tax reliefs you were eligible to claim.
When Is a Mistake by an Accountant Legally Negligent?
A mistake is legally negligent only if it breaches the professional duty of care owed to you as the client. Accountants are required to exercise the skill and care expected from a competent member of their profession. A simple, isolated error might not be enough, but persistent failures or fundamental mistakes that go against accepted norms could amount to negligence.
What Do I Need to Prove in an Accountant Negligence Claim?
To succeed with an accountant negligence claim, you need to establish four elements:
- Duty: The accountant owed you a duty of care, typically set out in your engagement letter or service agreement.
- Breach: They breached that duty by failing to act with reasonable skill and care.
- Causation: Their breach directly caused your financial loss.
- Loss: The loss suffered must be real, measurable, and a direct result of the breach.
Proving every element is essential. Without clear evidence linking the accountant’s mistake to your financial loss, the claim may fail.
Can I Recover HMRC Penalties, Interest or Extra Tax From My Accountant?
If your accountant’s mistake leads HMRC to impose penalties, charge interest or demand additional tax, you may be able to claim for those losses, as long as they would not have arisen without the accountant’s negligence.
You cannot usually recover the tax you were always liable to pay, even if the error delayed its payment. However, penalties or interest charges that result purely from your accountant’s actions may be recoverable if you demonstrate a direct connection.
What Losses Can I Claim if My Accountant Was Negligent?
The losses you can recover from an accountant typically include any financial penalties, additional tax, or interest that result directly from their negligent act or omission. The courts will look closely at whether the accountant’s actions were the real cause of your loss.

What Evidence Is Needed to Prove Accountant Negligence?
To build a strong claim, you need clear evidence of both your engagement with the accountant and the resulting losses. Key documents include:
- The engagement letter or service agreement
- Email correspondence and formal letters
- Tax returns or accounts submitted by the accountant
- Notices from HMRC or penalty letters outlining fines or demands
- Proof of payments and financial records showing loss
- A timeline of relevant events and dates
Step-by-Step: How to Bring a Professional Negligence Claim Against an Accountant
The typical steps in an accountant negligence claim are:
- Collect and review evidence: Organise your documents, correspondence and statements.
- Seek legal advice: Get an expert view from a professional negligence solicitor.
- Initial complaint: Raise the issue with the accountant’s firm if possible. Some issues resolve at this stage.
- Letter of claim: Your solicitor formally sets out your case, including the facts and what you are seeking.
- Notify insurers: The accountant’s professional indemnity insurer will usually be informed at this point.
- Settlement discussions: Many cases resolve without formal court proceedings after negotiations.
- Issue court proceedings: If a settlement is not reached, proceedings can be started in court.

Our expert lawyers can support you at every stage, from preliminary advice to negotiating a settlement or going to court.
What Laws and Deadlines Apply to Suing an Accountant for Negligence?
The Limitation Act 1980 sets out the main time limits for professional negligence claims in England and Wales.
- An action for damages for negligence, other than for certain personal injuries, must be brought within fifteen years from the negligent act or omission.
- A period of three years from the date when the cause of action accrued or from the date of knowledge, if later, may also be relevant depending on the circumstances.
If you do not start your claim within the relevant time limit, it is likely to be time-barred and cannot be pursued. Factors such as when the loss happened and when you discovered the mistake will affect how long you have.
Do I Need to Complain to the Accountant or Regulator Before Suing?
You are not legally required to complain to your accountant’s firm or a regulator before starting legal proceedings, but it is usually wise to try resolving the issue first. Many firms have internal procedures for complaints, and some professional bodies offer mediation.
- Early complaint may result in a swift remedy or compensation, avoiding court.
- Regulator involvement can lead to disciplinary action, but does not guarantee you will recover your losses.
You can discuss with our solicitors whether to make a complaint, refer the issue to a regulator, or begin a legal claim straight away.

Frequently Asked Questions
Can I sue my accountant for giving incorrect tax advice?
Yes, if the advice was so poor that it fell below the standard of a reasonably competent professional and caused you a financial loss.
What if my accountant made a mistake but I did not lose any money?
You will only have a negligence claim if you suffered a loss as a direct result of the mistake. Without financial loss, there is usually no claim.
Is my accountant liable if HMRC investigates me because of their error?
An investigation on its own is not enough for a claim. However, if you incur penalties or interest directly due to the accountant’s negligence, you may be able to recover those amounts.
Do I have to give my accountant a chance to fix the mistake before suing?
While there is no absolute legal rule, it is usually better to raise your concerns with the accountant first and see if the mistake can be rectified.
How do I prove my accountant’s mistake actually caused my loss?
You must provide robust evidence linking the accountant’s error to your financial loss—such as correspondence, returns, penalty notices and accounts records.
Can I recover my legal fees for suing my accountant?
It is sometimes possible for the successful party to recover legal costs from the other side, depending on the outcome and the court’s discretion.
What should I do if the accountant’s insurer denies responsibility?
If negotiations do not succeed, you may need to escalate the matter and start legal proceedings. Immediate professional advice is vital in these cases.
Are there time limits if I only discovered the mistake years later?
The Limitation Act 1980 sets out time limits based on both when the negligent act happened and when you discovered it. If unsure, seek advice as soon as possible.
Will making a complaint to the accountancy regulator affect my claim?
A regulator complaint is a separate process. While it may help your case, you must still prove negligence and loss to recover compensation.
What if my accountant has closed the business or retired?
You may still claim against their professional indemnity insurer or, in some cases, the successor firm. Do not assume you cannot claim simply because the practice closed.
