Why Jermyn & Co?
What is a Tax Investigation?
A tax investigation is an enquiry conducted by HMRC to ensure that your tax affairs are accurate and compliant. These investigations may arise randomly, as HMRC has the authority to check any taxpayer’s records without specific cause.
Recent statistics show a sharp increase in HMRC’s efforts:
- 416,000 tax enquiries were conducted in the 2023-2024 financial year, up from 327,000 the previous year.
- With the UK government addressing a “£22bn black hole” in national finances, HMRC is expected to escalate its efforts further, particularly targeting areas of underreported income.
Investigations may range from routine checks, such as VAT or PAYE reviews, to more in-depth examinations of business or personal transactions.

Why Do Taxpayers Get Investigated?
Tax investigations can be triggered for several reasons, including:
-
Random Selection
Many investigations are initiated randomly, regardless of whether you’ve made any mistakes in your tax filings. -
Specific Industry Focus
Certain industries are under greater scrutiny, including:- Sectors with complex VAT or PAYE systems.
- Businesses affected by IR35 regulations or employment status disputes.
-
Unusual Patterns or Data Discrepancies
HMRC’s Connect database gathers data from multiple sources, including:- Banks, land transactions, and council tax records.
- Digital marketplaces (e.g., eBay, Airbnb, Vinted).
- Social media profiles.
- Any discrepancies or unusual activity could raise red flags.
-
Side Hustles and Extra Income
HMRC is increasingly focused on individuals earning through side businesses, such as pet breeding, property rentals, or selling on digital platforms.

The Consequences of a Tax Investigation
Tax investigations can be a significant burden, with consequences such as:
Time and Stress
Responding to HMRC’s requests and compiling documentation is time-consuming and stressful, potentially disrupting your business or personal life.
Expensive Professional Fees
Expert representation during a tax enquiry can incur substantial costs beyond your regular accounting fees.
Potential Penalties and Fines
If HMRC identifies errors, you could face penalties, interest on unpaid taxes, or legal action.
