Our Specialities
Tax problems that require exceptional expertise
We are a tax-exclusive firm. Every matter we handle is a high-stakes tax issue. Not average, not above average – exceptional.

SARS Tax Dispute Resolution
Dispute tried, failed, and getting nowhere? Just facing one now? We are one of South Africa’s foremost tax dispute expert firms. Our impeccable success rate is built on strategic, tactical case-building that gives clients the best possible outcome against SARS.

Voluntary Disclosure Programme
Post the Purveyors judgment, VDP applications are complex. SARS seems to look for reasons to reject VDP applications. We specialise in VDP applications with an excellent track record in securing full relief for qualifying taxpayers. We are known for preparing and submitting some of the best VDP applications.
