What Is Accountant Negligence and Can I Sue in the UK?
Accountant negligence occurs when an accountant fails to perform their professional duties to the expected standard, causing you financial harm. In England and Wales, both contractual and common law duty of care protect clients: where your accountant gives wrong advice, misses deadlines, or fails to follow regulations, you may be entitled to sue.
A successful claim requires showing:
- The accountant owed you a duty of care.
- They breached that duty (acted negligently).
- Their action or omission directly caused you quantifiable loss.
Professional indemnity insurance is mandatory for accountancy firms and often covers claims, enabling out-of-court resolutions.
Do not delay—insurers may try to settle swiftly and minimise your recovery. Early legal input can greatly increase your negotiation strength.
Our solicitors review your claim quickly and help you preserve your legal position from day one.
How Do I Know If My Accountant Was Negligent?
You must show your accountant acted below the standard of any reasonably competent accountant in the same circumstances. Key warning signs include:
- Repeated or significant errors in your accounts or tax filings
- Ignoring critical deadlines or overlooking new tax law
- Failing to spot fraud or significant irregularities in records
- Poor communication or unexplained delays that caused you loss
David, a shop owner in Liverpool, discovered his company’s accounts included duplicate expense entries and misapplied VAT. As a result, he faced a £7,500 shortfall and a warning from HMRC. His accountant admitted a junior had prepared the work unsupervised.
If you experience repeated errors or losses linked directly to your accountant’s failings, you may have strong grounds for a claim.
Unsure whether your situation qualifies? Our fixed-fee negligence review provides clarity on your rights and next steps.
What Are Common Mistakes That Lead to Accountant Negligence Claims?
Many negligence claims arise from recurring professional errors, such as:
- Missing tax or Companies House filing deadlines, which trigger penalties and investigations
- Providing inaccurate advice on VAT or tax planning, leading to overpaid or underpaid liabilities
- Failing to spot obvious signs of fraud or mismanagement within your accounts
- Negligently handling the completion or audit of company accounts, resulting in additional HMRC scrutiny or penalties
- Not advising on the proper structures for reliefs or allowances, causing missed savings
- Poor document management, exposing you to compliance breaches
Firms are also responsible for the negligence of their staff or subcontractors if you suffer loss as a result.
You can often claim even if you signed off returns or accounts, provided you reasonably relied on professional advice and your accountant failed to flag or correct key risks.
Identifying the precise link between the negligent act and your specific losses is critical.
What Are My Legal Rights If I’ve Lost Money Due to Bad Accounting?
If your accountant’s mistakes led to financial loss, penalties, or missed opportunities, you have the right to claim for:
- Compensation restoring you to your position before the error
- Reimbursement for penalties, excess tax, additional interest, or corrective costs
- Consequential losses, such as lost business or costs of remedying the mistake, if they were reasonably foreseeable
Sarah’s restaurant faced a £12,000 HMRC penalty plus £3,000 in interest because her accountant failed to file accounts on time. She also paid £1,500 for urgent professional help to correct her filings. These direct and resulting losses were recoverable in her successful negligence claim.
Even if there was no deliberate wrongdoing, carelessness or failure to meet professional standards can give rise to full compensation rights.
To accurately value your potential claim and ensure you recover all losses, consult our professional negligence lawyers for a confidential assessment.
How Much Compensation Can I Claim for Accountant Negligence?
Compensation is designed to put you in the position you would occupy had the accountant done their job correctly. Typical claim items include:
- Repayment of unnecessary tax, HMRC fines, and penalties
- Additional interest and surcharges imposed due to accountant fault
- Lost profits from failed investment or business opportunities
- The cost of instructing fresh accountants to repair errors
- Court-awarded legal costs, where appropriate
You must directly link each element of your loss to the original error.
Keep clear, dated records of all extra costs, time wasted, and professional fees. Documenting the impact improves your negotiating position and the value of your claim.
Our lawyers assist in quantifying and evidencing all financial losses for maximum recovery.
How to Prove an Accountant Was Negligent and Recover Financial Loss
Succeeding in a negligence claim requires four elements:
- Duty of Care: Your accountant owed you a legal or contractual duty.
- Breach of Duty: Their conduct fell below a reasonable standard.
- Causation: This breach caused your loss directly.
- Loss: The loss is concrete and quantifiable.
Courts refer to professional standards, case law, and regulatory codes when assessing these claims.
Essential Evidence Needed for a Successful Claim
A strong claim is supported by clear, organised evidence:
- Service agreements, engagement letters, or contracts confirming the relationship
- Full records of emails, letters, and meeting notes
- Copies of accounts, tax returns, and supporting financial documents
- Written advice, calculations, or auditor notes showing the error
- Evidence of penalties, demands, missed opportunities, or lost income
- Invoices/receipts for correction or new professional services
- Documentation of when the error was discovered and reported
Emily, a freelance designer, collected a four-year email history in which her accountant wrongly advised her on VAT thresholds. She submitted this, together with HMRC fines totalling £8,800, to support her compensation claim—resulting in full reimbursement plus professional costs.

Step-by-Step Guide: How to Sue an Accountant in the UK
Following the correct stages maximises your chance of recovery:
- Gather all critical documents: contracts, emails, accounts, and evidence of loss.
- Seek an initial solicitor assessment to clarify negligence and likely outcomes.
- Itemise and quantify every element of your financial and reputational loss.
- Send a formal Letter of Claim to the accountant, outlining breaches and loss.
- Wait for their (or insurer’s) reply under the Professional Negligence Pre-Action Protocol—usually up to 3 months.
- Attempt negotiation and early settlement.
- If necessary, commence court proceedings (in the County Court or High Court).
- Prepare for trial, mediation, or settlement negotiations.
Most negligence claims are resolved before trial, especially with detailed evidence and legal expertise.
Should I Complain, Report, or Sue?
Consider these options in sequence:
- Use the accountant’s own complaints procedure for a potential internal resolution.
- Make a regulatory or professional body complaint—especially where you seek disciplinary action.
- Bring a legal compensation claim if your financial loss is substantial or unresolved by other routes.
Your goal—compensation, accountability, or both—will guide your best next steps.
How to Make an Official Complaint Before Taking Legal Action
Most regulators require that you attempt to resolve issues directly with the firm first:
- Submit a clear, written complaint, explaining the facts, loss, and what you need to resolve matters.
- Wait for a written response—usually within 8 weeks.
- If still dissatisfied, escalate to the relevant regulator (such as ICAEW, FRC, FCA).
Presenting evidence of a reasonable, failed complaint improves your legal footing if the claim enters court, showing you tried to avoid litigation.
When complaints and regulatory reports are insufficient for fair compensation, court proceedings remain available.

What Laws and Deadlines Apply to Accountant Negligence Claims?
Key legal principles in England and Wales require claimants to meet strict requirements to secure compensation.
Professional Negligence: Duty, Breach, Causation, Loss
A successful negligence claim must prove:
- The accountant owed you a duty of care (generally by contract).
- They failed to meet an expected professional standard.
- The breach caused you loss directly—no unrelated factors intervened.
- You suffered a genuine, quantifiable financial loss.
Courts apply the reasonable professional test and review compliance with statutory and ethical codes.
Limitation Periods: How Long Do I Have to Make a Claim?
Action must be taken before key deadlines:
- The usual time limit is six years from the date of the negligent act or loss (Limitation Act 1980).
- If the loss was hidden or only later discovered, you have three years from knowledge (subject to a maximum of 15 years from the act, under Section 14A Limitation Act 1980).
Ali, an IT consultant in Birmingham, discovered accountancy errors in 2022 that first occurred in 2016. He had until 2025 at the latest to bring his claim, as the three-year ‘date of knowledge’ rule applied.
Missing these deadlines will usually prevent you from claiming, no matter how strong your case.
Relevant Statutes and Professional Rules
Your case may involve:
- Limitation Act 1980 (deadlines for action)
- Civil Procedure Rules (claims process/protocol)
- Pre-Action Protocol for Professional Negligence
- Professional codes: ICAEW, ACCA, FRC
- Key judgments including Caparo Industries plc v Dickman [1990] 2 AC 605, which created the modern test for a duty of care in negligence claims
Early action is crucial—gather evidence and consult a specialist solicitor as soon as you suspect a professional mistake. Delay is the most common cause of missed claims.
Our team can review your case against all relevant deadlines and maximise your chance of a successful outcome.
What Do the Courts Say About Suing Accountants for Negligence?
Leading cases in England and Wales have established the legal framework for accountant liability:
| Case | Facts | Outcome | Why It Matters |
|---|---|---|---|
| Caparo Industries plc v Dickman [1990] 2 AC 605 | Negligent audit; investors relied on published accounts, suffered loss | No duty to shareholders; clear duty to instructing client | Sets out duty of care and foreseeability test |
| Armitage v EY [2020] EWHC 2964 (Comm) | Incorrect tax advice led to major financial loss | Accountant liable for complex tax errors | Demonstrates liability for failing to advise adequately on specialist issues |
| Berg v Sadler & Co [2013] EWCA Civ 1587 | Accountant failed to challenge overcharged tax | Client’s losses recoverable | Clarifies duty to spot and challenge clear errors |
These cases confirm that accountants must meet strict professional standards, and courts enforce remedies for breaches that cause loss.

How to Report a Bad Accountant: ICAEW, FRC, FCA and Complaint Procedures
You can pursue redress along regulatory, as well as legal, avenues:
- ICAEW (Institute of Chartered Accountants in England and Wales): handles investigations and discipline for members and firms.
- FRC (Financial Reporting Council): investigates serious audit and ethics breaches.
- FCA (Financial Conduct Authority): deals with accountants also authorised for financial services.
Procedural steps:
- Write first to the accountancy firm, keeping detailed records.
- Escalate unresolved complaints to the relevant regulatory body, including all evidence.
- In certain cases, use the Financial Ombudsman Service or industry-specific schemes.
Reporting to a regulator may result in sanctions for the accountant, but compensation for your loss usually requires a separate court claim.
For step-by-step advice, our team can guide you through both reporting misconduct and making a structured legal claim.

Frequently Asked Questions
Can I sue my accountant if they missed a tax deadline?
Yes. If an accountant’s failure to meet a deadline led to HMRC penalties or loss, you can claim for those losses, provided you reasonably relied on their expertise and instructions.
What if my accountant’s mistake caused an HMRC fine?
You can claim both the fine and additional related losses, including interest and correction costs, if they stem directly from the accountant’s negligent actions.
Will I need to go to court to claim against my accountant?
Many claims are resolved before any court hearing. With strong evidence, experienced solicitors often negotiate settlements with insurers at the pre-action stage.
How do I calculate the losses caused by accountant negligence?
List every direct and consequential loss: penalties, overpaid/underpaid tax, lost profits, extra professional fees, and business disruption. Keep receipts and financial records for each item.
Can I claim if I relied on bad advice but haven’t lost money yet?
Normally, actual and demonstrable loss is required for a claim. If you have not yet suffered a loss, reporting may still lead to regulatory action.
Who regulates accountants in England and Wales?
The main accountancy regulators are ICAEW, ACCA, FRC, and the FCA (for financial services work). Check your accountant’s registration and membership status.
What costs are involved in suing an accountant for negligence?
Costs vary depending on claim value and the need for expert evidence, but many claims are handled on a fixed-fee or no-win, no-fee basis. Court-awarded costs or insurance may offset the risk of losing.
What if my accountant is no longer trading?
Claims can usually proceed against their professional indemnity insurer, provided they held valid cover when the negligence occurred.
Can I complain and sue at the same time?
Yes. Regulatory complaints and civil claims are separate routes and can proceed in parallel, provided you follow rules and meet deadlines for both.
Will suing my accountant damage my business’s reputation?
Most negligence claims are confidential, especially when settled out of court and handled by lawyers using insurer protocols.
