HMRC has significantly expanded its use of digital technology to help identify potential tax discrepancies and improve compliance across the UK tax system.

Using information received from a wide range of sources, HMRC can compare data against tax returns to identify inconsistencies that may require further review. While many enquiries relate to genuine mistakes or requests for additional information, an HMRC compliance check can still be time-consuming, stressful and costly.

Understanding how HMRC carries out compliance checks—and ensuring you have the right professional support—can help you respond confidently if your business or personal tax affairs are ever reviewed.

 

How Does HMRC Use Data?

HMRC receives information from a variety of sources to help verify the accuracy of tax returns.

These may include:

• Banks and financial institutions (where permitted by law).
• Employers through PAYE reporting.
• Companies House.
• Land Registry and property transaction records.
• Overseas tax authorities through international information-sharing agreements.
• Digital platforms where reporting obligations apply.
• Other government departments.

HMRC combines this information with sophisticated data analytics to identify unusual patterns, discrepancies or missing information that may warrant further investigation.

Can Honest Taxpayers Be Investigated?

Yes.

Receiving an HMRC enquiry does not necessarily mean HMRC suspects fraud or deliberate wrongdoing.

Many compliance checks arise because of:

• Differences between information held by HMRC and submitted tax returns.
• Large or unusual transactions.
• Requests for clarification.
• Routine compliance activity.
• Industry-specific reviews.

Even taxpayers who have taken reasonable care when preparing their tax returns may be asked to provide additional information.

What Happens During an HMRC Compliance Check?

The scope of an HMRC enquiry will depend on the circumstances.

HMRC may request:

• Accounting records.
• Bank statements.
• Invoices and receipts.
• Payroll information.
• VAT records.
• Supporting documentation for tax returns.
• Explanations of particular transactions.

Responding thoroughly and within the required timescales is important to help resolve the enquiry as efficiently as possible.

The Cost of an HMRC Enquiry

Even where no additional tax is ultimately payable, dealing with HMRC can involve significant professional time.

Your accountant may need to:

• Review financial records.
• Prepare technical responses.
• Liaise directly with HMRC.
• Gather supporting evidence.
• Explain complex tax issues.
• Negotiate points raised during the enquiry.

These professional costs can become substantial, particularly if the enquiry continues for several months.

What Is Tax Investigation Fee Protection?

Tax Investigation Fee Protection helps cover the professional fees incurred when your accountant represents you during an HMRC compliance check or tax enquiry.

Subject to the policy’s terms, conditions and limits, cover may include professional representation for a range of HMRC enquiries, allowing you to obtain expert support without worrying about unexpected professional costs.
