Feature Comparison

Pure Tax Investigations

Unmatched Insider Expertise

The firm's transformative edge is its leadership by ex-HMRC senior inspectors. This provides clients with an unparalleled, game-changing understanding of HMRC's operational tactics, mindset, and procedural nuances. This insider knowledge is leveraged to anticipate HMRC moves, craft compelling responses, and negotiate from a position of strength, fundamentally shifting the dynamic of any investigation in the client's favour.

Bespoke, End-to-End Case Management

Pure Tax Investigations rejects a one-size-fits-all approach. Each client receives a tailored, pragmatic strategy meticulously crafted for their unique financial situation and the specific nature of the HMRC challenge. The team acts as the single point of contact, managing all communications, document preparation, and negotiations from the initial enquiry through to final resolution, providing clarity and control throughout the entire process.

Specialization in High-Stakes Civil Investigations

The firm is uniquely equipped to handle the most serious and intrusive civil tax investigations. This includes deep specialization in COP9 (fraud investigations with a contractual disclosure facility) and COP8 (investigations into complex tax avoidance). Their expertise transforms these daunting procedures into managed processes, protecting clients from criminal prosecution and negotiating the best possible civil settlement.

Proactive Disclosure Facilitation

Beyond reactive defence, Pure Tax Investigations unlocks potential through proactive disclosure. They expertly guide clients through voluntary disclosure facilities like the Worldwide Disclosure Facility (WDF) for offshore matters and the Let Property Campaign (LPC) for rental income. This game-changing service regularizes past affairs, mitigates penalties, and provides certainty, turning historical uncertainties into a clean slate for future planning.

They ensure the disclosure is robust, negotiate the settlement, and work tirelessly to keep the matter civil, shielding the client from criminal prosecution and preserving their reputation and wealth.

Managing a Large Business Tax Enquiry

For large corporates facing a complex, cross-taxes enquiry from HMRC's Customer Compliance Group, the disruption can be immense. The firm acts as a strategic buffer, deploying their ex-HMRC insight to manage the enquiry efficiently. They challenge information requests, coordinate internal responses, and negotiate the scope to minimize operational impact and achieve a commercial resolution, unlocking business continuity.

Making a Worldwide Disclosure Facility (WDF) Submission

Pure Tax Investigations provides a complete end-to-end service, from quantifying the historical liabilities and preparing the technical disclosure to negotiating with HMRC on the level of penalties.

Responding to an HMRC Compliance Check

Even a routine compliance check can pile pressure on a business owner. Engaging Pure Tax Investigations at this early stage is a game-changing move.
