What Is an HMRC Enquiry?
HMRC can open an enquiry into your tax affairs for a number of reasons – sometimes at random, sometimes due to inconsistencies or red flags. These investigations usually fall into three categories:
- Limited Scope HMRC Enquiries
This is the most common type of HMRC check. They’ll ask you to provide evidence for one or two specific figures on your tax return – often income, expenses or dividends. If you’re able to respond quickly and accurately, the enquiry is usually closed without further issue.
Already a Carbon client?
We don’t charge existing clients for limited scope HMRC enquiries – it’s all part of the service.
- Full Scope HMRC Enquiries
A full scope enquiry is more in-depth. HMRC will ask for detailed documentation to support your accounts and tax returns, such as:
- Sales and purchase invoices
- Expense receipts
- Business bank and credit card statements
- Cheque books and paying-in books
This can cover one or more accounting years. If discrepancies are found, HMRC can impose significant penalties – up to 100% of the tax due – plus interest.
Whether the enquiry is random or triggered by specific information, it’s vital to have an expert on your side to protect your position and guide you through what can be a time-consuming and stressful process.
- COP9 Investigations (Code of Practice 9)
HMRC uses COP9 when it suspects serious tax fraud – usually involving over £100,000. These are the most serious form of investigation short of criminal proceedings and can last months, even years.
If you’ve received a COP9 letter, you must respond carefully and quickly. We can help you:
- Understand your rights and obligations
- Prepare a voluntary disclosure (if applicable)
- Negotiate with HMRC on your behalf
- Settle tax, penalties and interest efficiently
