Tax legislation can be a major challenge, as a single line can be reasoned in countless different ways and the outcomes can be drastically different, with billions of pounds in profit or loss lying in the balance. To the outsider, resolving a tax dispute can be a complicated puzzle filled with pieces such as statues, legal precedents, financial and technical components, all seemingly unbendable and rigid in their structure. To a lawyer like Rebecca Murray, who practices at Devereux Chambers, the situation is controlled, strategic and even more so, crucially ethical.
Putting on a reputation as the defender of tax disputes of utmost prowess, marked by a calm and composed approach, Rebecca has worked on the tax consulting papers, alongside other documents and disputes, as well as cases that have the potential to transform how private and even HMRC clients conduct their businesses. Surrounded by legal experts like herself, Rebecca is the only tax lawyer who is able to transcend the law while remaining on point and ‘bring to the practice ‘life’ – that is, the capacity to put a face to the principles of every matter she tackles.’
Devereux Chambers: A House of Experts
To track Rebecca’s work-related history, you should first know what your ‘professional home’ is. Devereux Chambers is not a conventional law firm. It is a collection of independent lawyers, each practicing a different branch of law, yet joined by a common thread of reputation of excellence.
Devereux is recognized across the revenue, employment, personal injury, commercial, international arbitration, and technology fields as a ‘tax set’ of powers. The members are frequently engaged in some of the most intricate and high-profile legal matters, both within the UK, and abroad.
It is within this environment – interdependent, intellectually demanding, and multidisciplinary – that Rebecca flourishes. ‘I work on every case as part of a new team with a unique set of skills. I engage with tax specialists in every branch of tax and value their input. Many excellent concepts emerge from these technical discussions,’ she states.
The respect one has for other professionals is a hallmark of their practice. In her view, law, at its best, should not be a solitary pursuit but a collaborative endeavor aimed at unearthing the truth and dispensing justice.
Sculpture a Career in Complexity
The depth and width of her practice are both remarkable. There are few practitioners who work so seamlessly between advisory and litigation. She is able to do so between and indirect and direct taxes, and corporate and private clients of all kinds.
“When I get instruction to advise on transactions, it’s usually at the level of advising the company and the shareholders,” she says. “Because I know so many details, I can see solutions to problems which others fail to see. Even today, I participate in the initial stages of discussions with HMRC because I am able to develop arguments which are of value to customers who are at a standstill.”
The ability to work as both as a strategist who tries to stop the litigation from escalating and as a litigator who deals with the litigation is a very rare skill. Most lawyers prefer to do one or the other. Rebecca, however, is able to do both.
Her philosophy about disputes rests on three unwavering principles:
- Preparation – “You cannot be too prepared. Familiarity with evidence and the law is everything.”
- Adaptability – “You must learn to abandon a strategy that is not serving your client. Cases evolve quickly; you need to think on your feet.”
- Composure – “Having a cool head is an obligation for your client and the court. Cheap tactics are distractions – I refuse to use them and refuse to intimidate others myself.”
Case Study: MORAN V HMRC
Rebecca’s court instincts surfaced at Moran V HMRC [2025] UKFTT 540, where she served as sole counsel for HMRC in a case involving seven witnesses and several complex legal issues.
At the center of the dispute was whether the applicant’s deceased ex-husband had established an offshore trust structure for tax prevention purposes. The applicant’s case was strongly based on the testimony of “SD”, a loyal colleague from the 1990s, who had provided a statement stating that no legal advice had been taken at the time.
Rebecca had meticulously prepared an interrogation designed to dismantle this claim. But when she heard SD interact with the judge while being sworn in, her instincts told her that something was wrong.
“I realized that she didn’t even understand what was in her own statement,” Rebecca recalls. “I abandoned my plan at that moment.”
Instead, she turned. She drove SD to a paragraph describing the trust structure and asked if she had heard of “Namib”, a company mentioned in her statement. SD replied, “No”. When did Rebecca press even more – did SD write the statement? – The witness replied outraged, “Yes, why did you ask that?”
Rebecca’s calm answer cut the theater: “Well, you wrote this very accurate paragraph about the trust structure, but I just asked about it and you seem to know nothing about it.”
The facade collapsed. SD admitted that he knew nothing about the structure and could not remember whether advice had been taken. The cornerstone of the applicant’s case collapsed and Rebecca guaranteed a decisive victory.
The case illustrates not only preparation, but the ability to trust instincts, adapt strategy in the middle of a court hearing, and use simplicity as a devastatingly effective tool.
The Power of Written Advocacy
Although the presence of the Rebecca Court is formidable, her written advocacy is equally powerful. It is known for its ability to distill complex statutory dispositions of clear and logical analysis – “as equations,” she says – and writing in short and impact phrases.
“I only cite the principles of the cases in which I trust, not long passages. Judges appreciate clarity.”
In Trachtenburg V HMRC, a case with great consequences of range of the HMRC power to evaluate the charges of the pension plan, Rebecca’s written submissions were so effective that the judges of the Superior Court opened the hearing, “saying,” We say their skeleton argument; We just want to hear from you on any additional points. ”
For Rebecca, this moment was surreal. “There were two explanations: either my skeleton was so clear that I had done the job, or the opposite! I had the cautious view that it was the opposite and decided to cut the points of my opponent as simply possible.”
In Beresford, where the question was whether an office activity with management was an investment or an active business attracting relief from inheritance taxes, Rebecca used a “evidence note” to anchor the judge’s attention to the key facts. Similarly, in Bell and other V HMRC, involving complex assessments of value, her high -level oral submissions were reinforced by detailed written evidence, materially adopted by the judge in her decision.
Her approach shows that law is not about volume, but accuracy – knowledge when brevity takes more weight than elaboration.
Purpose and Innovation in Tax Law
Tax law has a reputation for rigidity, but Rebecca sees differently. “Every customer is in a different situation. I always know that I can make a positive difference to them – this is the goal of my work.”
Her creativity combines a relentless factual analysis with the empathy of understanding customers’ personal bets. “I try to understand first, then to be understood. With this approach, I know I can always make a difference.”
This philosophy resonates deeply with customers who often face not only financial risks but pressures of reputation and emotional.
Growth Through Authenticity
For Rebecca, growth as a lawyer and as a person is inseparable. “Personal growth is what is reflected in the world of your business,” she says. “That’s why I have no scruples in ‘keeping it real’ in my LinkedIn posts. I don’t believe in separating professional life from who you are as a person. They are part of the same whole.”
It is a refreshing perspective in a profession frequently covered in formality. For Rebecca, authenticity is not weakness – it is strength. It allows it to connect with clients, colleagues and even judges at the human level.
Leadership and Inclusion
One of the qualities that differentiates Rebecca is her inclusive approach to leadership. “There are many lawyers who ignore their team, thinking they know better. I think both arrogant and ignorant. I have seen points being missed because people were not heard.”
Your approach is collaborative. She ensures that the voice of all team members is heard, even if the final strategic decision rests on her. This inclusive style not only strengthens legal arguments, but also promotes respect and loyalty among those with whom it works.
When asked what qualities she seeks in team members, her answer is simple and revealing: honesty, integrity, energy, enthusiasm and respect for others. These are non-negotiable, the basis of confidence in a high risk environment.
Life as Tax Barrister
Rebecca’s role is multifaceted. Depending on the case, it may be advising companies, litigating in court or working closely with private clients and HMRC. Each day brings a new team, a new set of challenges and often new areas of the law to master.
The happiest part of your routine? The intellectual exchange. “I like to have technical debates with other experts. It’s amazing how tax lawyers can be moved by the details!” She laughs.
It is in these moments – because of statutes, challenging interpretations, testing arguments – that Rebecca finds joy. For her, the law is not just a profession, but a passion.
Values That Drive
In essence, Rebecca is driven by values that transcend the court: integrity, inclusion and respect. These principles guide all the cases she assumes, all the strategies she creates, and all the decisions she makes.
Her refusal to cut songs, her insistence on listening to all the voices and her dedication to justice make her not only an effective but also reliable lawyer.
The Influence of Rebecca Murray
In the demanding and high pressure world of the tax law, Rebecca Murray stands out not only for her cool brightness, but for her character. She showed that the success of the law is not the highest voice, but about being the clearest, the fairest and the most prepared.
Her influence extends beyond its customers and cases. She represents a model of leadership based on human authenticity, collaboration and understanding – qualities that are often neglected in the profession.
While she continues to shape the future of the Devereux Chamber tax law, Rebecca Murray exemplifies why she belongs among the most influential women in law, 2025.
She is more than a lawyer. She is a defender of the people, a strategist of clarity and leader who proves that integrity and success are not mutually exclusive – they are, in fact, inseparable.
