What's Your HMRC Investigation Risk?

Five questions, built from the actual triggers HMRC's Connect system uses. Get your risk score instantly. Free 60-minute consultation with our tax investigation team available on request.

Question 1 of 5 20%
In the last 3 years, have you filed any tax return late?
How is the score calculated?

The five questions map directly to the most common HMRC investigation triggers we see in practice: late filings, multiple income streams, cash-based or high-risk sectors, undeclared digital platform income, and unusually high expenses for the sector.

HMRC's Connect system cross-references over 30 data sources including bank interest returns, Land Registry, employer payroll, digital platform reports (eBay/Vinted/Airbnb under DPI rules), and overseas tax authority data (CRS/FATCA). The questions reflect the data points Connect can independently verify against your return.

Maximum score: 12. Bands: 0–3 = low, 4–7 = moderate, 8+ = high. The score is a directional indicator, not a guarantee.
