HMRC does not always open an enquiry because fraud is suspected
When You Need a Tax Investigation Specialist
HMRC Enquiry Letters
If HMRC has opened an enquiry or compliance check, early specialist advice helps control the response and avoid unnecessary mistakes.
Code of Practice 8
COP8 cases can involve serious technical disputes and complex tax questions that need careful handling from the outset.
Code of Practice 9
COP9 matters are highly sensitive and should never be approached casually, especially where disclosure decisions must be made.
VAT Investigations
VAT checks often focus on records, treatment, claims and historical reporting, and can expand quickly if issues are found.
PAYE & Employer Checks
Employer PAYE compliance reviews can involve payroll, benefits in kind, expenses and historical treatment of staff or directors.
Tax Errors or Disclosures
If returns are wrong or income has not been reported, the right disclosure strategy can make a significant difference to outcome.
Tax investigations are rarely about one letter alone
What Our Tax Investigation Service Covers
A tax investigation service should do more than forward HMRC letters. Good representation means reviewing the underlying position, controlling the information flow, preparing accurate responses, protecting your rights and working toward the best achievable outcome.
HMRC Correspondence
We handle written responses, deadlines and information requests so communication with HMRC is controlled and consistent.
Record Review and Risk Analysis
We assess returns, supporting records and weak points before responses are sent, helping avoid accidental admissions or poor positioning.
Enquiry Representation
We deal directly with HMRC on your behalf and guide you through meetings, questions and requests for information. Penalty Mitigatio
Penalty Mitigation
Where tax is due, we focus on reducing unnecessary penalties by improving the quality and timing of responses.
Disclosure Support
We advise on voluntary disclosures, offshore matters and historic corrections where the position needs careful review.
Settlement and Time to Pay
Where liabilities arise, we can help negotiate practical next steps, including payment arrangements where appropriate.
Different HMRC interventions create different levels of risk
Which HMRC Tax Investigation Are You Facing?
Not all HMRC investigations are the same. A random aspect enquiry, a VAT dispute, an employer compliance visit and a COP9 case all need different handling. The right strategy depends on what HMRC is asking, how serious the issue is and whether wider corrections may be needed.
01
Aspect and Full Enquiries
Some enquiries focus on one point in a return, while others widen into a much broader review of your affairs.
02
Schedule 36 Notice
Some enquiries focus on one point in a return, while others widen into a much broader review of your affairs.
03
VAT and Employer Disputes
Some enquiries focus on one point in a return, while others widen into a much broader review of your affairs.
04
COP8 and COP9 Cases
Some enquiries focus on one point in a return, while others widen into a much broader review of your affairs.
The biggest risks often come from how a case is handled early
Why Tax Investigation Advice Matters
The quality of the early response can shape the direction of the entire enquiry. Poorly handled communication, missing records, unnecessary explanations or the wrong disclosure strategy can increase cost, widen the scope of the investigation and make penalty outcomes worse.
Control the Response
A specialist helps decide what should be said, what should be reviewed first and how to respond properly to HMRC.
Protect the Position
Good advice helps reduce avoidable mistakes, challenge assumptions and make sure the case is handled on the right basis.
Reduce Stress & Disruption
Tax enquiries are intrusive. Professional representation helps clients keep the issue contained and continue with normal life or business.

Clients come to us when they need calm, structured support in stressful circumstances. They value clear advice, careful handling and the confidence that HMRC matters are being dealt with properly.
When HMRC opened a review into our VAT and payroll records, I needed specialist advice quickly.

Their support was thorough, professional and exactly what I needed.

I contacted Tax Accountant after receiving HMRC letter about historic tax issues linked to a property transaction. They reviewed the position carefully, guided me through the risks and managed the response. I felt reassured and would highly recommend them for tax investigation support.

Your Questions - Our Answers
We are here to help you with any questions you may have
What is a tax investigation service?
A tax investigation service helps individuals and businesses deal with HMRC enquiries, compliance checks, disclosures and formal investigations in a structured way. This usually includes reviewing records, assessing the underlying tax position, handling correspondence with HMRC and helping the client decide the safest next step. Good support is not only about answering questions. It is about protecting your position, reducing avoidable mistakes and making sure the matter is handled properly from the start. HMRC investigations can involve Income Tax, Corporation Tax, VAT or PAYE, and early advice often makes a significant difference.
When do I need a tax investigation accountant?
You may need a tax investigation accountant as soon as HMRC opens an enquiry, asks for documents, raises a compliance check or suggests that earlier returns may be inaccurate. Early advice is especially important where the issue involves VAT, PAYE, rental income, offshore matters, disclosures, or more serious cases such as Code of Practice 8 or Code of Practice 9. Many clients seek help only after they have already replied to HMRC, but that can create unnecessary risk. The earlier the position is reviewed, the easier it is to manage the response and avoid widening the enquiry.
What happens during an HMRC tax investigation?
An HMRC tax investigation usually starts with a letter explaining the return, tax year or issue under review. HMRC may then ask for records, explanations, calculations or meetings, depending on the type of enquiry. Some investigations remain narrow and focus on one point. Others become broader if HMRC believes more than one area may be affected. A key part of tax investigation advice is deciding what the enquiry is really about, what evidence is needed and how responses should be framed so the position is not made worse by rushed or incomplete explanations.
Can a tax investigation specialist help with HMRC enquiries?
Yes. A tax investigation specialist can deal with HMRC on your behalf, review the records, identify technical issues and prepare responses that are accurate and properly structured. This is often valuable where the client is unsure why HMRC is asking questions, where the records are incomplete, or where earlier returns may need correction. On your live page, you already position this as representation through enquiries, compliance checks and formal investigations, and that is exactly the role a specialist should perform.
What triggers a formal HMRC tax investigation?
What is the difference between an aspect enquiry, a full enquiry and a civil investigation?
An aspect enquiry looks at one or more specific issues in a return. A full enquiry reviews the return more broadly and may extend into wider facts and records. A civil investigation usually reflects a more serious level of concern and may arise where HMRC believes there is significant tax at stake or where behaviour is in question. Your current page already distinguishes these types of intervention, and that distinction matters because the response strategy, evidence burden and penalty exposure are not always the same.
What are my obligations once HMRC opens a tax investigation?
Once HMRC opens an enquiry, you generally need to respond on time, provide information that is lawfully requested and avoid making incomplete or misleading statements. That does not mean every request should be answered casually or without review. One of the main reasons to seek tax investigation advice early is to check the scope of HMRC’s request, confirm what records exist, and make sure your response is accurate, proportionate and consistent with the actual position. This is especially important where there may be errors in earlier returns or gaps in the records.
How are penalties determined during a tax investigation?
Penalties are not based only on the extra tax due. HMRC will also consider whether the behaviour was careless, deliberate, or deliberate and concealed, and whether the taxpayer took reasonable care. The quality of cooperation, the timing of disclosure and the accuracy of the explanation can all affect the final penalty position. Your current page already covers these points well. A tax investigation accountant can help review the facts, challenge unfair assumptions and present the case in a way that reduces unnecessary penalty exposure.
Can HMRC extend a tax investigation to earlier years?
Yes. HMRC can look at earlier years if it believes the issue is not limited to the period first reviewed. The time limits depend on the behaviour involved and may be longer where HMRC believes the error was careless or deliberate. This can increase both financial exposure and the volume of records that may need to be reviewed, which is why the legal basis and scope of any extension should be checked carefully before responding.
What documents are usually requested during a tax investigation?
HMRC commonly asks for bank statements, accounting records, invoices, payroll information, dividend records, tax returns and supporting calculations relevant to the years under review. In personal tax cases, this may also include rental schedules, pension records or benefit information. In business cases, it may involve VAT records, payroll data and company accounts. Documentation quality often affects how quickly and effectively an enquiry can be resolved.
Can tax investigation accountants help reduce penalties?
Yes, in many cases. Penalties are influenced by behaviour, timing and cooperation, not just the tax difference itself. Tax investigation accountants can help by reviewing the facts carefully, correcting weak responses, making timely disclosures where appropriate and presenting the position in a way that reduces unnecessary penalty exposure. This is often one of the most important reasons for getting specialist help early, especially where the facts are sensitive or incomplete.
How much does tax investigation advice cost?
The cost depends on the type of enquiry, the number of years involved, the volume of records and the level of HMRC engagement. A focused aspect enquiry will usually cost less than a multi-year disclosure, a VAT investigation, or a COP8 or COP9 case. What matters most is whether the advice helps contain the issue, improve the handling of HMRC communication and reduce the risk of unnecessary tax, penalties or escalation.
Do you handle both personal and business tax investigations?
Yes. Tax investigation support can cover both individuals and businesses. For individuals, this may include Self Assessment enquiries, undeclared income issues and personal tax compliance reviews. For businesses, it can include Corporation Tax, VAT, PAYE and broader employer or company-level checks. The right approach depends on the type of taxpayer involved, the taxes under review and the seriousness of the issues raised by HMRC.
