Deeploy vs Pure Tax Investigations (HMRC Defence)

AI Discovery and Onboarding

Gain complete visibility into your AI landscape from day one. Deeploy helps you discover, catalog, and onboard every AI system across your organization into one central registry. You can connect to any existing machine learning or generative AI platform without disruptive migrations, eliminating blind spots. This creates a single source of truth for what AI is running, where, and who owns it, providing the foundational inventory needed for any governance program.

Control Frameworks

Navigate complex AI regulations with ease using Deeploy's guided control frameworks. The platform comes with pre-built templates for major standards like ISO 42001 and the NIST AI RMF, or you can build a custom framework tailored to your internal policies. These frameworks help you classify the risk level of each AI system in minutes and establish clear accountability with structured approval processes, making compliance straightforward and manageable.

Control Implementation

Turn high-level governance policies into enforceable, engineer-friendly actions. Deeploy automatically translates your chosen control framework into clear, actionable requirements for each AI system. It accelerates compliance by up to 90% using smart templates and auto-collecting evidence from your AI pipelines. This feature takes the repetitive, manual work out of governance, ensuring that rules are actually followed by the teams building and deploying the AI.

Real-Time Monitoring

Proactively prevent AI incidents before they impact your users or business. Deeploy monitors AI performance and behavior in real-time, sending instant alerts for issues like model drift, performance drops, or anomalies. For LLMs, you can add tracing and guardrails to protect outputs. This continuous oversight allows you to identify and fix problems early, ensuring your AI systems remain reliable, fair, and effective in production.

Specialist Ex-HMRC Leadership

Our team is led by Amit Puri, a former senior HMRC Tax Inspector. This insider perspective is invaluable. We understand HMRC's tactics, operational approaches, and thought processes, which allows us to anticipate challenges, communicate effectively with investigators, and build the strongest possible defence strategy for your specific situation.

Comprehensive Investigation Defence

We manage the full spectrum of HMRC engagements. This includes defending clients during serious civil investigations like Code of Practice 9 (COP9) for suspected fraud and Code of Practice 8 (COP8) for complex avoidance, as well as handling routine business compliance checks and comprehensive, cross-tax enquiries into large corporate entities.

Proactive Tax Disclosure Management

We don't just defend; we also help you regularise your affairs proactively. Our specialists expertly guide clients through voluntary disclosure facilities like the Worldwide Disclosure Facility (WDF) for offshore matters and the Let Property Campaign (LPC) for undisclosed rental income, aiming to minimise penalties and secure a finalised position with HMRC.

Bespoke, Client-Centric Service

Every client receives a tailored service. We listen first, then evaluate your unique circumstances. Our approach is pragmatic and commercial, designed to address your immediate concerns, realise your long-term aspirations, and preserve your wealth. You get direct access to experienced, qualified advisers dedicated to your case.

Achieving EU AI Act Compliance

For organizations operating in or selling to the European market, Deeploy provides a structured path to compliance with the EU AI Act. It helps you inventory all AI systems, classify them by risk level (prohibited, high-risk, limited risk, minimal risk), implement the required controls for high-risk AI, and automatically generate the necessary documentation and audit trails. This turns a complex regulatory challenge into a manageable, ongoing process.

Centralizing Oversight for Fragmented AI

Many companies find their AI systems scattered across different teams, vendors, and cloud platforms with no unified oversight. Deeploy acts as a central governance layer, bringing everything into one dashboard. This gives CIOs, risk officers, and AI leaders a holistic view, enabling them to manage risk, allocate resources effectively, and ensure consistent standards are applied to every AI application, no matter where it lives.

Enabling Safe AI in Sensitive Industries

In regulated sectors like healthcare, finance, or mental health services, AI must be exceptionally reliable and transparent. Deeploy's real-time monitoring and built-in explainability features allow these organizations to deploy AI with confidence. Clinicians or compliance officers can review the "why" behind an AI's decision, and human feedback loops can be integrated to continuously improve system safety and trustworthiness.

Accelerating MLOps with Governance-by-Design

For AI engineering and MLOps teams, governance is often seen as a bottleneck. Deeploy integrates governance directly into the deployment workflow. By providing clear requirements and automating evidence collection, it allows data scientists to iterate and deploy models faster—sometimes reducing the process from weeks to hours—while automatically building the compliance documentation needed for approval and audit.

Facing a COP9 "Tax Fraud" Investigation

If you have received a COP9 letter, HMRC suspects serious fraud. This is a critical time. We step in immediately to manage the Contractual Disclosure Facility (CDF) process, providing the strategic advice and robust representation needed to navigate this high-stakes civil investigation and work towards a financial settlement, avoiding criminal prosecution.

Managing a Complex COP8 Enquiry

Code of Practice 8 investigations target complex tax avoidance or sophisticated technical issues. Our specialists analyse the intricate details of your arrangements, prepare detailed technical arguments, and liaise with HMRC's specialist units to defend your position and resolve the enquiry with clarity and certainty.

Making a Voluntary Disclosure

If you have undisclosed income, gains from offshore assets, crypto, or rental profits, we can help you come forward voluntarily. We manage the entire disclosure process under the correct facility (like WDF or LPC), ensuring it is complete, accurate, and presented in a way that mitigates penalties and brings finality.

Responding to an HMRC Compliance Check

Even a routine business enquiry can be stressful and time-consuming. We act on your behalf, handling all communication with HMRC, gathering the required information, and ensuring the check is concluded as smoothly and swiftly as possible, preventing it from escalating into a more serious investigation.

Deeploy is your all-in-one AI governance platform, designed to bring order and trust to the complex world of artificial intelligence. Think of it as the central command center for every AI system in your organization.

Deeploy solves this by providing a unified layer of oversight, compliance, and monitoring. It's built for organizations of all sizes that are scaling their AI initiatives and need to manage risk, meet regulations like the EU AI Act, and maintain transparency. With flexible onboarding that connects to any MLOps or GenAI platform, real-time explainability, and automated audit trails, Deeploy transforms AI from a scattered collection of models into a well-governed, trustworthy asset. It empowers both technical teams and business leaders to scale AI faster, with confidence and complete control.

What types of AI systems can Deeploy manage?

Deeploy is designed to be platform-agnostic. It can govern a wide variety of AI systems, including traditional machine learning models (built on platforms like MLflow, Sagemaker, or Azure ML), third-party vendor AI solutions, and generative AI applications and Large Language Models (LLMs). Its flexible onboarding connects to your existing stack without forcing a migration.

How does Deeploy help with real-time explainability?

Deeploy provides built-in tools that help you understand how your AI models make decisions. For ML models, it can generate feature importance charts and local explanations for individual predictions. For LLMs, it offers tracing to see how an output was constructed. This transparency is crucial for debugging, building trust with end-users, and meeting regulatory requirements for high-risk AI.

Can we customize Deeploy for our internal policies?

Absolutely. While Deeploy offers ready-to-use frameworks for major international standards, its flexibility is a key strength. You can fully customize control frameworks to match your organization's unique internal policies, risk appetite, and industry-specific regulations. You can define your own controls, risk classifications, and approval workflows.

Is Deeploy suitable for a company just starting with AI?

Yes, Deeploy is valuable at any stage of your AI journey. For beginners, it helps establish good governance practices from the start, preventing future technical debt and compliance headaches. It provides the structure to scale AI responsibly. Starting with governance in place is much easier than trying to retrofit it onto dozens of unmanaged AI systems later on.

Is a COP9 tax fraud investigation serious?

Yes, a Code of Practice 9 (COP9) investigation is very serious. It is undertaken by HMRC's Fraud Investigation Service when they have a suspicion of serious tax fraud. The process is designed to secure a financial recovery (tax, interest, and penalties) on a civil basis. However, it operates under the shadow of potential criminal prosecution if the terms of the contractual disclosure are not followed correctly, which is why expert guidance is essential from the very start.

What is the difference between a tax investigation and a compliance check?

A compliance check is a routine review by HMRC to confirm your tax return is accurate and you are paying the right amount of tax. An investigation is more serious and invasive, often triggered by suspicions of significant errors, avoidance, or fraud. Investigations like COP8 or COP9 are far more in-depth, intrusive, and carry greater risks of substantial penalties.

Why should I use a specialist instead of my regular accountant?

While your accountant is vital for day-to-day affairs, tax investigations require specific expertise. Specialists like us have deep, current knowledge of HMRC's investigation tactics and procedures. We provide dedicated, robust defence strategies and act as an independent buffer, which can relieve immense pressure and often leads to a better, more commercial outcome.

What are the benefits of making a voluntary disclosure?

Making a voluntary disclosure to HMRC before they come to you has significant benefits. It demonstrates co-operation, which HMRC looks upon favourably. This typically results in substantially lower penalties compared to if HMRC discovers the undeclared tax themselves. It also allows you to regularise your affairs, gain peace of mind, and avoid the stress of a full investigation.
