Why HMRC Tax Problems Are Increasing
HMRC is now more aggressive and better equipped than ever. They have:
- Recruited thousands of new compliance officers
- Invested heavily in AI, data analytics, and behavioural tracking tools
- Launched public-reporting campaigns encouraging people to “report tax cheats”
- Improved access to bank, platform, property, and employment data
This means ordinary taxpayers — not just high earners — are now far more likely to be contacted by HMRC.
Common HMRC tax problems now include:
- Compliance check letters
- Undeclared self-employed income
- Rental or online trading not declared
- VAT and PAYE discrepancies
- Large unexplained bank deposits
- Contractor & freelancer enquiries
- COP6 and COP9 investigations
- Estimated tax debts
- Allegations of deliberate behaviour
HMRC’s monitoring systems now cross-reference a huge amount of digital data — far beyond what most people realise.
HMRC’s Use of AI to Track Taxpayers
HMRC’s AI-driven system, known internally as Connect, analyses billions of data points from:
- Banks & building societies
- Credit card providers
- Airbnb, eBay, Etsy, Amazon, Uber, Deliveroo
- Land Registry
- DVLA
- Social media & lifestyle indicators
- Overseas banks via information-sharing agreements
This AI flags even small inconsistencies — such as bank deposits, spending patterns, or online sales — and triggers automatic enquiries. These enquiries often begin with innocent-looking letters, but if handled incorrectly, they can escalate rapidly.
The Public Is Now Encouraged to Report People
HMRC now offers incentives and rewards to members of the public who report:
- Suspected undeclared work
- Cash-in-hand activity
- Benefit discrepancies
- Rental income not declared
- Suspected tax evasion
- This includes anonymous tip lines and online reporting tools.
Many HMRC enquiries now start from neighbour reports, ex-partners, business rivals, or disgruntled employees rather than data alone. Another reason why early, expert defence is essential.
