Facing an HMRC Tax Investigation? We Can Help.
If you’ve received an HMRC letter or are worried about undeclared income, you’re not alone.
HM Revenue & Customs (HMRC) is running several focused campaigns to identify taxpayers with unpaid or underreported tax. Whether it’s rental income, online sales, or other sources, we provide expert help to guide you through investigations and voluntary disclosures — protecting you from penalties and legal risks.
What Are HMRC’s Current Tax Investigation Campaigns?
HMRC is actively targeting specific areas where undeclared income is common. Here’s what you need to know:
1. Let Property Campaign (LPC)
HMRC’s Let Property Campaign targets landlords who have not declared rental income from residential properties. This includes:
- Single or multiple rental properties
- Rooms rented above the Rent a Room Scheme threshold
- Holiday lets and Airbnb rentals
- Landlords living abroad who rent UK properties
HMRC now receives data from online platforms like Airbnb, Booking.com, and Vrbo, making it harder to hide rental income. If you haven’t declared all your rental earnings, voluntary disclosure under this campaign can reduce penalties and avoid criminal action.
2. Online Sales and Side-Hustles Campaign
HMRC is cracking down on undeclared income from online marketplaces such as eBay, Etsy, Vinted, and Airbnb. From January 2024, digital platforms must report sellers’ income to HMRC, and many taxpayers have received “One to Many” letters prompting them to disclose income within 30 days.
If you sell goods or services online and haven’t declared your earnings, it’s important to act quickly to avoid interest and penalties.
3. One to Many (OTM) Campaigns
These campaigns send “nudge” letters to groups such as charities, partnerships, and individuals suspected of underreporting tax. While not formal investigations, they encourage you to review your tax affairs and voluntarily disclose any unpaid tax before HMRC takes further action.
4. Serious Investigations: COP8 & COP9
For complex or suspected fraudulent tax cases, HMRC uses COP8 and COP9 investigations. These are serious enquiries that can lead to penalties or criminal prosecution. Early expert advice is critical if you receive such an investigation notice.
