Our tax disputes and investigations team advises on tax and financial crime. We are best known for our approach to matters that require some element of crisis management due to the complexity or sensitivity of the problem. We advise on some of the most significant and high-profile tax and financial crime issues. We do not want to end up in litigation but, if dispute resolution fails, we fight for the right outcome for you in the Tribunal or Courts having assembled the right team to run the case in the right way. We are experts in advising on technically complex tax risks, managing crisis related events, conducting investigations and disclosure, managing discovery and liability risks in transactions, and creating robust compliance programs for businesses.
With deep industry knowledge and a thorough understanding of how tax and regulatory/enforcement authorities operate around the world, we guide you through every stage of the process - helping you to proactively manage risks, navigate audits, and resolve disputes efficiently. From early-stage risk management and pre-emptive counsel, to handling information requests during audits and investigations, we are committed to protecting your interests.
We also act for clients at all stages of a criminal investigation and prosecution relating to the most serious of financial crime-related offences, including dawn raids, arrest responses and criminal investigations, and the freezing or seizure of assets and goods. We assemble and manage multi-disciplinary project teams (drawing in IT specialists, forensic accountants, and clients’ personnel) to undertake forensic internal investigations on our clients’ behalf.
We are problem solvers; we unlock thorny problems to help clients achieve their aims; for example, by using insurance, litigation funding and other tools to manage and mitigate risks, or to allow an otherwise at-risk transaction to proceed. We also work with clients to design, implement, and review compliance programs to help them meet their tax, anti-money laundering, and other regulatory obligations.
With a proven track record of successfully resolving disputes through settlement negotiations and strategic litigation, we are focused on securing the best possible results for you.

Tax disputes
Tax disputes require an expert team. The subject matter is complex, appeals are heard before specialist tribunals and there are unique challenges to resolving disputes with HMRC.
The Kennedys team has extensive dispute resolution experience across all areas of direct and indirect tax, including in relation to customs and excise duties, and dealing with challenges involving cross-border, intra-group transactions, such as transfer pricing.
We have a strong record of resolving disputes with HMRC during enquiries and investigation and also through mediation. For those matters that cannot be resolved without litigation, our team of expert litigators are experienced in all forms of tax litigation, including through the tax tribunals system, higher courts on appeal and the judicial review of tax decisions.

Investigations and disclosures
Our team regularly assists clients in performing internal investigations and preparing disclosures to various regulatory bodies. We understand that identifying and dealing with a tax, fraud or other type of error or wrongdoing can be stressful and our team are on hand to manage the entire process on behalf of our clients, ensuring minimal disruption to our clients’ businesses and livelihoods.
We are used to acting quickly where our clients have identified an issue and launching full scale investigations within a short timeframe. We are well known for our crisis-management offering and that includes being able to provide our clients with immediate support and assistance in their time of need.
In order to fully understand the nature of an issue, it is often necessary to undertake forensic internal investigations under legal professional privilege. We work with third parties as necessary including digital forensic experts and forensic accountants to conduct detailed investigations.
Where it is deemed appropriate to make a voluntary disclosure to a regulatory authority, we will fully manage that process, including preparing detailed reports and conducting negotiations with the authorities in order to fully resolve all issues. We are increasingly finding that regulatory authorities expect a greater level of enquiry to be undertaken by taxpayers before they will accept the technical analysis advanced in a disclosure. The investigation stage is therefore of key importance and needs to be conducted fully and diligently.
We have significant experience in the following tax, bribery and corruption investigation work:
- Code of Practice 8 and Code of Practice 9 enquiries

Financial crime
We have extensive experience of advising clients on all of the main financial crime areas such as tax, money laundering, bribery and corruption. We are experts in crisis management and have a strong reputation for providing our clients with robust defence strategies to counter allegations made by domestic and foreign law enforcement authorities of financial crime related wrong-doing.
We regularly act for corporates and individuals that are subject to investigation and prosecution by agencies including the Serious Fraud Office, Crown Prosecution Service, Financial Conduct Authority and HM Revenue and Customs. Some of our lawyers have worked for these organisations in the past and can provide a valuable insight into their inner workings. We also have experience of representing clients in multi-jurisdictional investigations conducted by overseas agencies such as the IRS, US Department of Justice and INTERPOL.
In addition to advising clients on responding to investigations initiated by law enforcement agencies, the team also regularly advises clients that discover financial crime within their organisation (e.g. via a whistleblower or a notification by a third party) on how to respond, investigate and, where necessary, self-report to the relevant authorities in a managed way with a view to avoiding criminal prosecution.
The team is often praised for how closely we work with our clients that are facing allegations of financial crime. We like to spend time on site and meet face to face with our clients wherever possible to gather information directly and obtain an in-depth understanding of the issues that they are facing. We are sympathetic to the toll that dealing with a financial crime related issue can have on corporates and individuals alike. Therefore, we know how important it is to be supported and listened to, and to receive the right advice at the right time.
In addition to dealing with financial crime related issues on a reactive basis, we work in parallel with our clients to improve their financial crime related compliance programmes (e.g., anti-bribery and corruption, Criminal Finances Act, AML/CFT procedures) to reduce the risk of similar issues arising in the future.
We also specialise in tax-specific financial crime litigation and investigations including in respect of anti-money laundering penalties and applications for freezing orders, detention of cash and forfeiture under the Proceeds of Crime Act.

Tax insurance
We facilitate tax insurance solutions for our clients to help them reduce or eliminate the exposure of tax risks from challenge by a tax authority. Tax insurance is a fast-growing market with more insurers now offering this type of policy which is of great benefit to our clients as it means lower premiums and a wider range of taxes/jurisdictions able to be covered.
The goal of tax insurance is to mitigate financial risk and increase certainty by transferring a risk from the business to an insurer. Our team is experienced in designing insurance solutions that achieve this result for clients. This allows them to successfully manage the risks that they face and to provide peace of mind that they are covered in the event of scrutiny from the tax authorities.
Tax insurance can be utilised in a wide range of scenarios such as during group restructuring, during or after an M&A transaction and associated due diligence, or simply as a risk management tool during a company’s ongoing operations.
We take a holistic approach to tax insurance, advising our clients as to whether insurance may be a useful tool, consulting with brokers and underwriters on their behalf, and providing tax technical analysis to support an insurance submission. The team has established relationships with brokers and underwriters across multiple jurisdictions and so are able to fully manage the process on our client’s behalf.

Compliance
Our team is well placed to assist clients in the compliance and risk mitigation space. We regularly provide advice and guidance as well as design and implement bespoke policies and controls. The team offers extensive know-how in the management of local and global compliance obligations, working with clients as their businesses evolve and grow and ensuring ongoing compliance with the various regulatory requirements they face.
Businesses face a wide range of tax, bribery, anti-corruption and other compliance obligations, as well as further specific obligations imposed by regulatory bodies on certain businesses. Not only are businesses required to ensure certain policies and controls are in place, but it is also necessary to regularly review policies to ensure that they are updated and being implanted. We typically work with our clients on an ongoing basis to manage the evolving nature of their business and the regulatory landscape.
Examples include:
