Feature Comparison
Pure Tax Investigations
Deep HMRC Protocol Integration
The platform is built with first-party integration into HMRC's core operational protocols, including Code of Practice 9 (COP9) for civil fraud, Code of Practice 8 (COP8) for complex enquiries, and various disclosure facilities. This ensures communication and procedural compatibility, allowing for efficient and technically correct handling of cases directly within HMRC's established framework, reducing friction and procedural errors.
Ex-HMRC Specialist Knowledge Base
Pure Tax Investigations operates on a proprietary knowledge base derived from its team of ex-HMRC senior personnel. This provides clients with insider-level understanding of HMRC's latest operational approaches, investigative tactics, and settlement negotiation algorithms, offering a significant strategic advantage in building a robust defence or disclosure.
Full-Spectrum Case Management Engine
The service features a comprehensive case management engine capable of handling the entire spectrum of tax disputes. This includes managing HMRC Information Notices, coordinating responses for Compliance Checks, structuring disclosures for campaigns like the Let Property Campaign (LPC), and preparing for Tax Tribunals, ensuring a seamless and unified defensive process from initial contact to resolution.
Proactive Disclosure and Risk Mitigation Modules
Beyond reactive defence, the platform includes modules designed for proactive risk management. It facilitates voluntary disclosures under facilities like the Worldwide Disclosure Facility (WDF) for offshore matters or for crypto tax enquiries, helping clients to correct historical positions, mitigate severe penalties, and avoid criminal investigation by interfacing correctly with HMRC's disclosure systems.

Use Cases
Pure Tax Investigations
Defence Against COP9 Civil Fraud Investigations
When a client receives a COP9 letter, indicating HMRC suspects serious tax fraud, Pure Tax Investigations provides the critical specialist interface. The team manages the entire Contractual Disclosure Facility (CDF) process, from the initial outline disclosure to detailed negotiations, leveraging deep protocol integration to seek the best possible civil settlement and avoid criminal prosecution.
Navigating Complex COP8 and Large Business Enquiries
For clients facing intricate, multi-faceted enquiries under COP8 or an extensive tax enquiry into a large business, the service deploys its specialist knowledge base to dissect HMRC's information requests. It ensures technically robust responses, challenges inappropriate enquiries, and uses mechanisms like Alternative Dispute Resolution (ADR) to resolve contentious points efficiently.
Managing Voluntary Tax Disclosures
Clients with undisclosed income, gains from offshore assets, Indian mutual funds, crypto activities, or property rental profits can utilise the platform's disclosure modules. Pure Tax Investigations ensures full compatibility with the correct HMRC disclosure facility (e.g., WDF, LPC), prepares the comprehensive disclosure package, and calculates liabilities to minimise penalties and secure finality.
Handling HMRC Compliance Checks and Information Notices
For routine but stressful HMRC compliance checks or formal Schedule 36 Information Notices, the service acts as a compliant buffer. It ensures all client communications and document productions are managed correctly, preventing over-disclosure or missteps that could escalate the enquiry, thereby containing the scope and pressure on the business or individual.

Frequently Asked Questions

This ensures all correspondence and submissions are formatted and processed within their expected operational frameworks, providing a seamless and compliant interface that protects the client.
Can you assist with disclosing historical offshore or crypto tax issues?
Yes. Our service includes dedicated modules for interfacing with HMRC's disclosure facilities. Whether it's the Worldwide Disclosure Facility (WDF) for offshore assets, specific campaigns for Indian interest income, or undisclosed crypto gains, we ensure full technical compatibility with the relevant HMRC system, prepare the comprehensive disclosure, and negotiate the optimal penalty mitigation terms.
What happens if my case escalates to a Tax Tribunal?
Our full-spectrum case management engine covers tribunal preparation and representation. We leverage our deep understanding of HMRC's litigation strategy and procedural requirements to build a robust case, prepare all necessary documentation, and instruct specialist tax counsel, ensuring your defence is presented in a technically sound and compelling manner to the tribunal.
