THIS IS UNICUS
We like difficult problems.
We ask questions, interrogate the facts and think before we act. Then we bring technical depth, strategic judgement and persistence to finding the right way forward — with direct access to the people actually doing the work.
Who we are
Built around one idea: solve the real tax problem.
Tax problems may begin with an error, an omission, cash-flow pressure, poor advice or an unreasonable/incorrect SARS position. Our focus is what happens next — and how to resolve it properly.
Practical, not merely theoretical
We combine deep tax-law expertise with a commercial understanding of how tax decisions affect businesses, directors, families and professional advisers.
Client-centered by design
No two tax matters are identical. We develop a tailored strategy around the facts, the legal position, the procedural stage and the outcome the client needs.
Always current
Our team stays close to developments in tax legislation, SARS practice, court decisions and dispute procedure so that advice remains accurate, timely and defensible. You can see our tax update sessions on the Unicus Tax YouTube Channel and here.
What makes us different
Easy access. Technical strength. Practical solutions. No nonsense.
Our value lies not only in knowing tax law exceptionally well, but in knowing how to use that knowledge in a practical, constructive way to build, position and execute a case against SARS and how to control a Voluntary Disclosure
Easy access
You get direct and fast access to top quality tax specialists without endless red tape and without your matter and communications getting lost in layers of corporate bureaucracy.
Technical Strength
When it comes to technical strength, our experts are amongst the top technical minds in the country with exceptional depth of knowledge and experience. Our team includes tax lawyers, chartered accountants, former SARS audit experience and tax specialists.
Clear accountability
Clients receive honest advice, clear scope and transparent fees — without surprise invoices or vague processes.
Practical solutions
While we can be just as tax technical as the rest, our aim is for that technical strength to lead to practical and constrictive solutions that sound in law. We are also very mindful of the cost vs benefit principle and consider whether the likely outcome justifies the costs involved.
No nonsense
Our work is not limited to following standard SARS procedures. We know what the technical legal leverages against SARS are and how to use it. At the same time, we also know where a taxpayer’s position is too weak and we will not hesitate to tell you when pursuing a position is pointless or whether VDP is approriate.
