HMRC has invested significantly in data matching across property-related records. Information from letting agents, Land Registry records, tenancy deposit schemes, bank data, and international reporting agreements is cross-referenced against self-assessment returns to identify discrepancies. This is not a short-term campaign — it is a permanent shift in how HMRC monitors property income and transactions. Landlords, property investors, and anyone involved in property transactions should expect a higher level of scrutiny than in previous years.
The most common triggers for property-related investigations include rental income declared on your self-assessment that does not match income reported by your letting agent to HMRC, property sales recorded at Land Registry that were not followed by a 60-day CGT return, discrepancies between mortgage interest claimed as an expense and loan records held by lenders, undeclared rental income from properties identified through Land Registry ownership data, and foreign property income not declared under the Common Reporting Standard. Each of these involves data that HMRC holds independently — the investigation starts because HMRC’s data does not match yours.
Property investigations often involve multiple tax heads simultaneously. A single HMRC enquiry into a landlord can cover income tax on rental profits, Capital Gains Tax on disposals, SDLT on acquisitions, and sometimes VAT. The interaction between these taxes means that a correction in one area can have knock-on effects in another. A general tax investigation specialist who does not understand property tax may not identify all the issues. A property accountant who does not understand HMRC enquiry procedure may not handle the response correctly. This is where our dual expertise is most relevant.
Before opening a formal investigation, HMRC often sends what are known as nudge letters. These letters encourage you to review your tax affairs and make corrections voluntarily. A nudge letter is not a formal investigation, but it is not optional correspondence either. Ignoring it escalates the position in HMRC’s risk assessment from potentially careless to potentially deliberate, which significantly increases penalty exposure if HMRC subsequently opens a formal investigation. We advise on the correct response to nudge letters and, where corrections are needed, make them through the appropriate disclosure route.
We review the HMRC correspondence and assess which data source triggered the investigation. We reconstruct the correct income and gains position from the available records. We prepare a comprehensive response addressing all of HMRC’s queries. Where the investigation reveals errors across multiple taxes, we deal with the entire position together rather than piecemeal. We manage the investigation through to resolution, negotiate on penalties, and ensure the outcome reflects the best position the facts support.
