HMRC explains in its "[About compliance checks](https://www.gov.uk/government/publications/general-information-about-compliance-checks-ccfs1a/about-compliance-checks-ccfs1a)" factsheet (CC/FS1a) that checks are part of its routine work to ensure the tax system is operating correctly, and that they can result in you paying more tax, less tax or no change at all. A compliance check can focus on an individual, partnership, company or other business structure and may cover taxes such as income tax, corporation tax, [PAYE](https://taxdisputes.co.uk/2026/03/ultimate-guide-to-avoiding-paye-nic-penalties-in-2026/) and [VAT](https://taxdisputes.co.uk/2026/02/how-to-apply-for-a-hardship-direction-in-vat-cases/). Checks range from straightforward questions about a single item on a return to wider reviews of several years' filings and related records. At the outset, [HMRC](https://taxdisputes.co.uk/hmrc-penalties/) will normally write to you to say it is opening a check, identify the tax and period under review and set out the information it wants. At this early stage, it is often sensible to take specialist advice from experienced[ HMRC ](https://taxdisputes.co.uk/hmrc-penalties/)[tax dispute solicitors](https://lexlaw.co.uk/contact-us/). ## Why HMRC Opens Compliance Checks [HMRC](https://taxdisputes.co.uk/hmrc-penalties/) can open a compliance check for several reasons, including risk‑based selection, random sampling, and information received from third parties. Risk indicators include inconsistencies between different returns, unusual trading patterns, or mismatches between your figures and data from employers, banks or overseas tax authorities. [HMRC’s](https://taxdisputes.co.uk/hmrc-penalties/) systems also use data‑matching and analytics to flag cases where the reported position appears unusual compared with similar taxpayers. In some situations, checks are triggered by specific intelligence suggesting that tax may have been understated or that reliefs may have been claimed incorrectly. A check does not automatically mean you have done anything wrong; [HMRC’s](https://taxdisputes.co.uk/hmrc-tax-appeals-solicitors-london/) own guidance recognises that many checks end with no adjustments or with errors corrected by agreement. However, the way you respond can influence [HMRC’s](https://taxdisputes.co.uk/hmrc-tax-investigations-solicitors-london/) view of your behaviour and any penalties, so careful handling is important. For complex tax disputes, the specialist team at [LEXLAW](https://lexlaw.co.uk/) has extensive experience advising on HMRC matters. ## HMRC’s Legal Powers: Schedule 36 Finance Act 2008 [HMRC’s](https://taxdisputes.co.uk/hmrc-tax-investigations/) main powers to obtain information and inspect records during a compliance check are set out in[ Schedule 36 to the Finance Act 2008](https://www.legislation.gov.uk/ukpga/2008/9/schedule/36). Under [Schedule 36](https://www.legislation.gov.uk/ukpga/2008/9/schedule/36), an HMRC officer may by written notice require a person to provide information or produce documents that are reasonably required to check a tax position or to collect a tax debt. There are different types of “information notice”, including a taxpayer notice (addressed to the person whose tax is being checked) and third‑party notices (addressed to, for example, banks or business counterparties). [HMRC](https://taxdisputes.co.uk/hmrc-penalties/) can also use a “financial institution notice” to obtain specified information directly from financial institutions subject to statutory conditions. ## Taxpayer Rights During a Compliance Check You have the right to be represented, meaning you can appoint a professional adviser or another person to act on your behalf in dealing with [HMRC](https://taxdisputes.co.uk/hmrc-penalties/). You are entitled to understand what [HMRC](https://taxdisputes.co.uk/hmrc-penalties/) is checking, which taxes and periods are under review, and why particular information has been requested. You should receive clear explanations of HMRC’s concerns and, if [HMRC ](https://taxdisputes.co.uk/hmrc-tax-investigations-solicitors-london/)believes something is wrong, an explanation of why it thinks that and what needs to be put right. If [HMRC ](https://taxdisputes.co.uk/hmrc-tax-appeals/)proposes to charge penalties or issue assessments, you generally have the right to ask for an internal review and, if necessary, to appeal to the independent First‑tier Tribunal (Tax Chamber) under the Tribunals, [Courts and Enforcement Act 2007](https://www.legislation.gov.uk/id/ukpga/2007/15) and the relevant tax and penalty provisions. [LEXLAW](https://lexlaw.co.uk/contact-us/) frequently represent clients in [HMRC ](https://taxdisputes.co.uk/hmrc-tax-investigations-solicitors-london/)reviews and tribunal appeals, drawing on experience of HMRC procedures and advocacy before the tax tribunals. ## How Compliance Checks Can Escalate Many compliance checks are resolved by agreement with minor adjustments or no change, especially where the taxpayer has taken reasonable care and co‑operates. However, some enquiries expand significantly if[ HMRC](https://taxdisputes.co.uk/hmrc-tax-investigations-solicitors-london/) finds evidence of serious inaccuracies, concealment or suspected evasion. Escalation of an [H](https://taxdisputes.co.uk/hmrc-tax-investigations-solicitors-london/)[M](https://taxdisputes.co.uk/hmrc-tax-investigations-solicitors-london/)[RC](https://taxdisputes.co.uk/hmrc-tax-investigations-solicitors-london/) compliance check can involve extending the review to earlier tax years, issuing additional or broader [Schedule 36](https://www.legislation.gov.uk/ukpga/2008/9/schedule/36) notices, and conducting more detailed scrutiny of bank accounts, ledgers, and financial transactions. Such measures increase the scope and intensity of the investigation, requiring careful management and professional advice. In more serious cases,[ HMRC](https://taxdisputes.co.uk/hmrc-tax-investigations-solicitors-london/) may move into civil fraud procedures, such as a Contractual Disclosure Facility process under its Code of Practice for suspected fraud, or consider a criminal investigation where it suspects deliberate tax evasion. Where escalation is likely, early s[pecialist advice](https://lexlaw.co.uk/contact-us/) can be crucial in managing risk, controlling disclosure and protecting against unintended admissions. ## Managing Risk During a Compliance Check Managing a compliance check effectively requires both technical tax knowledge and a strategic approach to [HMRC’s](https://taxdisputes.co.uk/hmrc-tax-appeals-solicitors-london/) information requests. Good record‑keeping and clear explanations often help resolve matters more quickly and reduce the risk of penalties. Where requests seem excessive or unclear, [professional advisers](https://lexlaw.co.uk/contact-us/) can help you discuss them with HMRC and, where appropriate, negotiate adjustments to the scope or timing. The Tax Team at [LEXLAW](https://lexlaw.co.uk/contact-us/) are used to liaising with[ HMRC](https://taxdisputes.co.uk/hmrc-tax-appeals-solicitors-london/) officers, narrowing information requests and helping clients strike the right balance between co‑operation and protection of their legal position. ## Key Takeaways on HMRC Compliance Checks [HMRC ](https://taxdisputes.co.uk/hmrc-tax-appeals/)compliance checks are a routine but significant part of the UK tax system, used to confirm that taxpayers have paid the right amount of tax and complied with their obligations. Under [Schedule 36 to the Finance Act 2008](https://www.legislation.gov.uk/ukpga/2008/9/schedule/36), [HMRC](https://taxdisputes.co.uk/hmrc-tax-appeals/) can require information, documents and, in some cases, access to business premises, but only where this is reasonably required and subject to legal safeguards and protections such as legal professional privilege. Understanding both [HMRC’s](https://taxdisputes.co.uk/hmrc-tax-appeals/) powers and your rights helps you respond proportionately and reduces the risk of unnecessary escalation or penalties. Where the issues are complex, the amounts at stake are significant, or there is concern about potential fraud allegations, obtaining early advice from [specialist HMRC tax disputes lawyers](https://lexlaw.co.uk/contact-us/) is often the most effective way to protect your position and work towards a fair, efficient resolution. ### Frequently Asked Questions (FAQ's) What is an HMRC compliance check? An HMRC compliance check is an enquiry conducted by HMRC to verify that a taxpayer’s declared tax position is accurate. It may involve reviewing tax returns, accounting records, bank transactions, and supporting documents. What rights do I have during an HMRC compliance check? Taxpayers have the right to understand the scope of the enquiry, know which tax years are under review, receive clear explanations of requested information, and seek professional representation to protect their legal position. What is a Schedule 36 notice? A Schedule 36 notice is a formal HMRC request for documents or information that is reasonably required to check a taxpayer’s position. Failure to comply can result in penalties, but the notice must comply with statutory requirements. When should I seek specialist advice? You should consider professional advice if HMRC is examining multi-year positions, large or cross-border transactions, if the notice seems broad or intrusive, if significant penalties are possible, or if civil fraud or criminal investigation is suggested. Can HMRC extend a compliance check to earlier tax years? Yes, HMRC can escalate a compliance check to include earlier tax years, issue wider Schedule 36 notices, and conduct detailed analysis of bank accounts, ledgers, and transactions if they identify issues requiring further investigation.
