In recent years, HMRC’s tax investigations have intensified, aiming to identify errors or under-reported income in tax returns. Compliance efforts brought in a record £41.8 billion during 2023-24. While it’s unclear how much of this total came from specific tax enquiries, HMRC’s focus on compliance is steadily increasing. Here’s what you need to know to stay prepared and handle documentation effectively.
Receiving a Tax Enquiry Letter
The first indication of a tax enquiry is usually an official notification letter from HMRC. This letter arrives in an A4 envelope and includes information on the enquiry process, your rights, and what is required from you. HMRC may not always provide a reason for the enquiry, but a polite phone call could sometimes yield more details.
Tax enquiries can be costly for both taxpayers and HMRC. Common triggers include inconsistencies between your tax returns and third-party data, several years of losses, unexplained income fluctuations, or figures that differ from industry norms.
What Documents Might Be Requested?
HMRC will outline the specific records they need in their enquiry letter. While you’re only legally required to keep certain records, they may request additional documents. For the self-employed and those with capital gains, records must be retained for at least five years from the 31 January filing deadline. Keeping these records for an extra year may offer extra security. In some cases of suspected dishonesty, HMRC can review records dating back 20 years.
For businesses, essential documents include:
- Receipts and invoices for expenses
- Employment contracts to validate payroll records
- Property documents (e.g., rental agreements, mortgage statements) for income and capital gains records
Under the Making Tax Digital (MTD) initiative, HMRC accepts digital records. These must be complete, legible, and connected to your quarterly submissions. Using digital tools that automatically upload records to cloud storage can help you stay compliant and organised.
The Importance of Bank Statements
Bank statements are critical records. Many banks only make statements available online for a limited period, so downloading and storing them securely is wise. Having accessible bank statements can simplify the enquiry process.
VAT Records and Small Purchases
If your business is VAT-registered, retaining VAT invoices is essential, though there are exceptions for smaller purchases:
- Receipts for car parking under £25 (including VAT) aren’t required.
- For supplies under £250, less detailed invoices can be accepted.
Cash Payments
For cash transactions, HMRC requires careful documentation. Claims for cash expenses may be disallowed if invoices or receipts are missing. If a document is lost, you may need to request a duplicate invoice or a letter from the supplier detailing the transaction. HMRC might ask for the supplier’s details, such as their address or National Insurance number, to validate the expense.
Third-Party Information
HMRC can request data from third parties, including suppliers, banks, or even customers, to verify your records. This could involve reviewing bank statements, receipts, or other relevant documentation.
Practical Advice: Keeping Your Records in Order
Keeping all deductible expenses well-documented can prevent future issues. HMRC has disallowed deductions when evidence is insufficient. Ensure your records are detailed and accessible to avoid complications during a tax enquiry.
Practical Example
Imagine a business owner pays a builder £5,000 in cash for renovation work. Without an invoice or receipt, HMRC may deny the deduction, even if the transaction is recorded in the business’s accounts. To prevent this, the owner could request a duplicate invoice from the builder, providing proof of the expense.
