Our team provides expert, robust defence for clients facing serious HMRC investigations under Code of Practice 9 (for suspected tax fraud) and Code of Practice 8 (for complex tax avoidance).

From the initial information notice to the final settlement, we manage the entire lifecycle of an HMRC compliance check or enquiry. Our approach is methodical and adaptive, ensuring all communications and document submissions are strategically handled to reduce client stress and limit the scope of HMRC's enquiries effectively.

Clients benefit directly from the unparalleled insight of Amit Puri, our director and ex-HMRC senior Tax Inspector.

Frequently Asked Questions
Dokta FAQ
How does Dokta's AI analysis work?
You simply drag and drop any document—a photo of a receipt, a scanned contract, or a PDF invoice—into Dokta. Within 60 seconds, our system combines Optical Character Recognition (OCR) with advanced Claude AI from Anthropic to read the text, classify the document type (e.g., invoice vs. quote), and extract key data like amounts, dates, and client details. This data is then presented for your validation, and the system learns continuously to improve accuracy.
Is my data secure and compliant with European regulations?
Absolutely. Data security and privacy are foundational to Dokta. All data is 100% encrypted using AES-256 standards and is hosted exclusively on Amazon Web Services (AWS) servers located in Paris, France. We are fully compliant with the EU's General Data Protection Regulation (GDPR), ensuring your business and client information is protected according to the strictest European laws.
What happens if I exceed my monthly document limit?
Dokta offers a transparent Free Discovery tier with 15 documents per month. If you exceed your plan's limit, you will be notified and can upgrade to a higher plan (Starter, Freelance, or Pro) that offers a larger monthly document allowance. This ensures you only pay for the capacity you need as your business grows and your document volume increases iteratively.
Can I connect Dokta to my accounting software?
Currently, Dokta focuses on providing a flawless, self-contained management experience and robust export functionality. You can export all your financial data—invoices, client lists, transactions—to a universal CSV file at any time. This file is formatted for easy import into any major accounting software or for sending directly to your accountant, ensuring a smooth handoff without manual data entry.
Pure Tax Investigations FAQ
What should I do if I receive a Code of Practice 9 (COP9) letter from HMRC?
Do not ignore it or respond directly without specialist advice. A COP9 letter indicates HMRC suspects you of tax fraud. Contact us immediately. We will help you understand your options, typically advising to enter the Contractual Disclosure Facility (CDF) to make a full disclosure and gain protection from criminal prosecution, guiding you through every iterative step of this critical process.
How long does a typical tax investigation take?
The duration varies significantly based on complexity, ranging from several months for a straightforward compliance check to multiple years for a serious COP9 investigation or large corporate enquiry. Our role is to manage the process efficiently, responding promptly to HMRC to prevent unnecessary delays, while continuously refining our strategy to work towards a timely resolution.
What is the difference between a compliance check and a tax investigation?
A compliance check is a routine review by HMRC to check the accuracy of a tax return or claim. A tax investigation is more serious and invasive, often triggered by suspicion of significant error, avoidance, or fraud (like COP8 or COP9). We handle both, applying a scalable and adaptive approach, with investigations requiring a more robust, defensive strategy.
Can you help if I have already started dealing with HMRC myself?
Yes, we can step in at any stage. Engaging us early is always preferable, but we can often rectify situations where dialogue has become problematic. We will review all previous correspondence, take over communication with HMRC, and implement a fresh, strategic approach to steer the case towards a better outcome, learning and adapting from the initial interactions.
