Receiving an HMRC compliance check can understandably make business owners concerned, particularly if they have never experienced one before. However, an HMRC compliance check does not automatically mean that a business has done something wrong. HM Revenue & Customs carries out compliance checks to establish whether tax has been paid correctly, the appropriate allowances and reliefs have been claimed, and tax records are accurate.
For UK businesses, being organised and responding properly can make the process much easier. Preparing financial records, understanding what HMRC is asking for and getting professional support where appropriate can help businesses manage a compliance check efficiently.
What Is an HMRC Compliance Check?
An HMRC compliance check is an examination of a taxpayer's tax position. HMRC may check areas such as tax returns, accounts and tax calculations, Company Tax Returns, VAT-related matters or PAYE records where a business employs people.
HMRC may contact a business by letter or telephone to explain what it wants to check and why. During the process, HMRC may request information or documents, discuss the business's tax affairs or, in some circumstances, arrange a visit to inspect premises, assets and records.
The scope of the check will depend on the circumstances of the business and the issues HMRC needs to establish.
Why Might HMRC Start a Compliance Check?
HMRC has the ability to check whether tax returns are accurate and complete. Certain circumstances may prompt a compliance check.
For example, HMRC may have questions about figures included on a tax return, a VAT repayment claim or the relationship between declared turnover and tax information.
A compliance check should therefore be treated as a request to establish the correct tax position rather than automatically assuming that a penalty or additional tax will result.
Step 1: Read the HMRC Letter Carefully
The first step is to carefully read the communication from HMRC.
The letter should explain what HMRC wants to check and may identify the tax period, tax type or records involved.
Do not ignore the letter or delay unnecessarily. Make a note of:
- The HMRC reference number
- The name and contact details of the officer
- The tax or taxes being reviewed
- The accounting or tax periods involved
- Information and documents requested
- Any response deadline
Understanding the scope of the check will help you organise the relevant information instead of sending large amounts of unrelated documentation.
Step 2: Gather Your Financial Records
One of the most important preparation steps is collecting the financial records relevant to the check.
Depending on the nature of the enquiry, HMRC may request information such as:
- Accounts
- Tax returns
- Invoices
- Receipts
- Bank statements
- Payroll records
- VAT records
- Expense information
- Business transaction records
- Supporting documentation for tax claims
HMRC may ask for specific information or documents during the compliance check. If you are unsure whether a document is relevant, it is sensible to discuss the request with your accountant or professional adviser.
Step 3: Check Your Records Before Responding
Before providing information to HMRC, review the relevant records carefully.
Look for inconsistencies between your accounting records, tax returns and supporting documents. For example, check whether income recorded in your accounting system agrees with the figures reported on relevant tax returns.
You should not alter records simply because HMRC is checking them. Instead, identify genuine errors or missing information and discuss them appropriately.
If you discover that something may be incorrect, getting professional advice can help you understand the appropriate way to respond.
Step 4: Organise Documents Clearly
Sending information in an organised format can make communication with HMRC easier.
Create folders for the relevant tax years or accounting periods and separate documents by category.
For example, you could organise records into:
- Sales and income
- Purchases and expenses
- Bank records
- Payroll
- VAT
- Tax returns
- Assets
- Correspondence
A clear document structure can make it easier to locate information when HMRC asks follow-up questions.
HMRC states that helping with a compliance check can help it complete the check more quickly and may affect the level of any penalty where one is applicable.
Step 5: Respond to HMRC Within the Required Time
Pay close attention to deadlines.
If HMRC requests information and you need more time to provide it, communicate with the officer dealing with the check. HMRC guidance recognises that there can be legitimate reasons why someone needs additional time, and businesses should raise difficulties rather than simply failing to respond.
Where a formal information notice has been issued, the notice will specify a period for providing the requested information. Failing to comply with certain notices can result in penalties.
Step 6: Consider Professional Support
An HMRC compliance check can involve technical tax and accounting matters.
Businesses may therefore choose to involve an accountant or tax adviser, particularly where the check is extensive or concerns potentially complicated issues.
HMRC confirms that taxpayers can have an adviser involved in the process. If you already have an authorised tax agent, HMRC may communicate with that agent about the check.
Professional support can help you understand HMRC's questions, organise documentation and communicate information accurately.
Step 7: Be Clear and Accurate
When communicating with HMRC, provide information that is accurate and relevant to the questions being asked.
If you do not understand a question, ask for clarification rather than making assumptions.
It is also important not to provide explanations that are inaccurate simply because you believe they will make the situation easier.
If an error has occurred, discuss it honestly with your adviser and the HMRC officer dealing with the case.
HMRC explains that cooperation and the quality of information provided can be considered when determining applicable penalties.
Step 8: Keep Copies of Everything
Businesses should keep copies of information supplied to HMRC during the compliance check.
Maintain a record of:
- Documents submitted
- Dates information was sent
- Emails and letters
- Notes of conversations
- Questions asked by HMRC
- Responses provided
- Any decisions or notices received
Keeping a complete record can make it easier to follow the progress of the compliance check and respond to later questions.
What Happens After an HMRC Compliance Check?
Once HMRC has completed its review, it will communicate the outcome.
If HMRC finds that everything is correct, the check can be closed. If HMRC identifies an underpayment or overpayment, the business may be required to make an adjustment. Depending on the circumstances, interest or penalties may also apply.
The outcome will depend on what HMRC finds during the check.
Businesses should carefully review any final decision and seek professional advice if they do not understand it.
What If You Disagree With HMRC?
A business does not necessarily have to accept every HMRC decision.
If HMRC makes a decision that carries a right of appeal, the relevant correspondence will explain the available options.
HMRC states that, generally, a taxpayer may provide new information, request a review by a different HMRC officer or appeal to an independent tribunal. The usual period for these options is 30 days from the relevant decision letter, although specific circumstances can affect the procedure.
Alternative Dispute Resolution may also be available in appropriate cases.
How to Reduce Future HMRC Compliance Risks
Businesses can take practical steps to maintain better tax and accounting processes throughout the year.
These can include:
- Keeping accurate financial records
- Reconciling business bank accounts regularly
- Retaining supporting documents
- Reviewing tax returns before submission
- Recording business expenses correctly
- Keeping payroll information organised
- Monitoring VAT records where applicable
- Meeting relevant filing and payment deadlines
- Reviewing unusual transactions
- Taking professional advice when uncertain
Good record keeping is not only useful during an HMRC compliance check. It can also support better financial management and business decision-making.
