HMRC Enquiry Investigation Support

Updated November 2025

If you've received an HMRC enquiry or investigation, you're not alone—thousands of businesses and individuals face HMRC enquiries each year, and having the right support makes all the difference. HMRC enquiries are compliance checks where HMRC reviews your tax returns, records, and accounts to ensure you're paying the right amount of tax and complying with tax law. HMRC investigations are more formal and detailed reviews, typically triggered by concerns about tax compliance, errors, or suspected tax evasion, and can result in additional tax, penalties, and interest. HMRC enquiry and investigation support helps businesses and individuals respond to HMRC enquiries, provide required information, understand their rights, and minimise additional tax, penalties, and interest (gov.uk Tax Compliance Checks).

Here's what you need to know:

  • HMRC enquiries review your tax affairs — HMRC checks tax returns, records, and accounts to ensure correct tax is paid
  • Investigations are more serious — Formal, detailed reviews that can result in additional tax, penalties, and interest
  • Professional support helps minimise impact — Understanding your rights, responding appropriately, and negotiating settlements can reduce additional tax and penalties
  • Early action is important — Responding promptly and professionally helps resolve enquiries more quickly and favourably

The problem is most people don't know how to handle HMRC enquiries or investigations effectively. They don't understand their rights, struggle to respond appropriately, don't know what information to provide, or find the process stressful and overwhelming. That causes problems—paying more tax than necessary, higher penalties, longer investigations, stress and worry, and potential damage to business reputation.

FAQs

HMRC Enquiry Investigation Support - Frequently Asked Questions

Common questions about HMRC enquiries, investigations, and tax compliance checks

An HMRC enquiry is a compliance check where HMRC reviews your tax returns, records, and accounts to ensure you're paying the right amount of tax and complying with tax law. HMRC enquiries can be: aspect enquiries (checking specific aspects of your tax return or accounts), full enquiries (comprehensive review of your tax affairs), compliance checks (routine checks to ensure compliance), random checks (random selection for compliance checks), or targeted enquiries (enquiries targeting specific issues or areas). HMRC has the right to check your tax affairs, and enquiries can result in additional tax, penalties, and interest if issues are found. It's worth getting professional help to respond to HMRC enquiries effectively and minimise impact.
In an HMRC investigation, HMRC conducts a detailed review of your tax affairs, typically triggered by concerns about tax compliance, errors, or suspected tax evasion. HMRC investigations involve: detailed review of tax returns, records, and accounts, requests for information and documents, meetings or interviews with HMRC, analysis of your financial affairs, identification of any issues or discrepancies, calculation of additional tax, penalties, and interest if issues are found, and negotiation or appeal if you disagree with findings. HMRC investigations are more serious than routine enquiries and can result in significant additional tax, penalties, and interest. It's worth getting professional help to handle HMRC investigations effectively and minimise impact.
To handle an HMRC enquiry, you should: review HMRC correspondence carefully (understanding what HMRC is checking and what information they're requesting), understand your rights and obligations (knowing what you must do and what your rights are), gather required records (collecting all requested records, documents, and information), prepare professional responses (drafting clear, complete, and accurate responses to HMRC), respond promptly (responding to HMRC requests within deadlines), communicate professionally (maintaining professional communication with HMRC throughout), seek professional help (getting professional support to ensure appropriate handling), and negotiate where appropriate (negotiating settlements to minimise additional tax and penalties). Professional help can ensure HMRC enquiries are handled effectively and minimise impact. It's worth getting professional help if you receive an HMRC enquiry.
You may need help with HMRC investigation if you: have received HMRC correspondence (enquiry letters, investigation notices, requests for information), don't understand what HMRC is checking (uncertainty about what's being investigated and why), are concerned about potential issues (worried about additional tax, penalties, or consequences), don't know how to respond (uncertainty about how to respond appropriately), want to minimise impact (wanting to minimise additional tax, penalties, and interest), need representation (wanting professional representation during meetings or interviews), or want peace of mind (wanting support and advice during what can be a stressful time). Most people benefit from professional help when facing HMRC investigations. It's worth getting professional help to handle investigations effectively.
Your rights during HMRC enquiries include: right to representation (you have the right to be represented by a professional advisor), right to fair treatment (HMRC must treat you fairly and reasonably), right to appeal (you can appeal HMRC decisions if you disagree), right to confidentiality (your information should be kept confidential), right to reasonable time (you should be given reasonable time to respond to requests), and right to explanation (you have the right to understand what HMRC is checking and why). Understanding your rights helps ensure fair treatment during HMRC enquiries. It's worth getting professional advice on your rights and how to protect them.
HMRC investigations vary significantly in duration: simple compliance checks may be resolved in weeks (typically 4–12 weeks), aspect enquiries may take months (typically 3–6 months), full enquiries or investigations can take much longer (typically 6 months to 2+ years depending on complexity), and investigations can be extended if complex issues are found or appeals are made. Investigation duration depends on: type of enquiry (compliance check vs. full investigation), complexity (simple issues vs. complex tax matters), cooperation (how quickly information is provided), and whether settlement or appeal is needed. It's worth getting professional help to resolve investigations as efficiently as possible while ensuring thoroughness.
If HMRC investigate you, you should: stay calm (enquiries are routine and don't necessarily mean you've done anything wrong), review correspondence carefully (understanding what HMRC is checking), understand your rights (knowing your rights and obligations), gather required records (collecting all requested information), respond professionally (preparing clear, complete, and accurate responses), respond promptly (meeting HMRC deadlines), seek professional help (getting professional support to ensure appropriate handling), cooperate with HMRC (providing requested information and cooperating with the enquiry), and negotiate where appropriate (working with HMRC to reach fair settlements). Professional help can ensure investigations are handled effectively and minimise impact. It's worth getting professional help if you're being investigated by HMRC.
Yes, you can appeal HMRC investigation results if you disagree with HMRC's findings. Appeals involve: reviewing HMRC's decision (understanding what HMRC has decided and why), assessing appeal grounds (determining whether you have valid grounds for appeal), preparing appeal (gathering evidence, preparing appeal arguments, submitting appeal), appeal process (going through appeal process, which may involve review, tribunal, or court), and appeal resolution (resolving appeal, which may result in HMRC decision being changed, upheld, or modified). Appeals can be complex and time-consuming, so it's worth getting professional help to assess whether appeal is appropriate and to prepare and represent appeals effectively. Professional help can improve appeal chances of success.
