Instant AI Document Analysis
Dokta's core functionality is its powerful AI and OCR engine that processes any uploaded document—be it a photo, scan, or PDF—in less than 60 seconds. It automatically identifies the document type (invoice, quote, contract) and extracts critical data such as amounts, due dates, client or supplier information, and tax details. This eliminates all manual data entry, ensuring accuracy and saving significant time while populating your business database automatically.

Anomaly Detection & Client Management
Beyond organization, Dokta proactively protects your business. Its AI scans for document anomalies like changed IBAN details, duplicates, inconsistent VAT numbers, or missing invoice numbering. Simultaneously, it automatically enriches contact details using SIRET numbers and assigns a payment behavior score to each client or supplier, building a complete, intelligent history for every business relationship you manage.

Pure Tax Investigations
Facing a Serious HMRC Fraud Investigation (COP9)
When an individual or business receives a Code of Practice 9 (COP9) letter from HMRC's Fraud Investigation Service, it indicates a suspected serious tax fraud. Pure Tax Investigations provides critical expert guidance through this daunting process, managing the contractual disclosure facility (CDF) process, preparing a robust disclosure report, and negotiating to secure the best possible civil settlement and avoid criminal prosecution.
Managing a Complex HMRC Enquiry into a Large Business
Large corporates undergoing intensive, cross-tax enquiries benefit from the firm's structured approach. Pure Tax Investigations acts as a strategic buffer, analysing HMRC's information requests, coordinating with the client's accountants, and deploying technical expertise to challenge HMRC's positions and achieve a commercial resolution that minimises disruption and financial impact.
Making a Voluntary Tax Disclosure
For clients with undisclosed tax liabilities related to offshore assets, rental property income, or crypto gains, the firm facilitates voluntary disclosures through HMRC's campaigns like the Worldwide Disclosure Facility (WDF) or Let Property Campaign (LPC). They ensure the disclosure is complete, accurate, and presented optimally to mitigate penalties and interest.
Responding to an HMRC Compliance Check or Information Notice
Even routine HMRC compliance checks can be burdensome. Pure Tax Investigations steps in to handle all communications, ensuring client responses to information notices (Schedule 36) are legally compliant and strategically sound, preventing a simple check from escalating into a wider, more invasive investigation.

Pure Tax Investigations FAQ
What makes Pure Tax Investigations different from my accountant?
While accountants handle compliance and routine tax filings, Pure Tax Investigations specialises exclusively in contentious tax matters and HMRC investigations. Their team includes ex-HMRC inspectors with direct experience conducting enquiries, giving them unique tactical and procedural insight to defend clients aggressively, which most general practice firms cannot offer.
What should I do if I receive a Code of Practice 9 (COP9) letter from HMRC?
A COP9 letter is extremely serious and requires immediate, expert attention. You should contact a specialist firm like Pure Tax Investigations immediately and before responding to HMRC. They will advise you on your options, typically involving entering the Contractual Disclosure Facility (CDF) to make a full disclosure and seek a civil settlement, which they will manage on your behalf.
Can you help with disclosures for offshore income or gains?
Yes, Pure Tax Investigations has extensive experience managing disclosures through HMRC's Worldwide Disclosure Facility (WDF) and other offshore campaigns. They ensure all historical income, gains, and related tax liabilities are correctly calculated and disclosed in a manner designed to secure the lowest possible penalties under the relevant legislation.
How do you charge for your tax investigation services?
Given the unique nature of each investigation, Pure Tax Investigations typically operates on a fixed-fee or agreed project-fee basis, tailored to the specific scope and complexity of the case. This provides clients with cost certainty from the outset. An initial consultation is offered to discuss the case details and provide a clear fee proposal.
