Ziliant Tax has achieved B Corp certification. Not as a marketing exercise—but as a line in the sand.
In an industry often associated with complexity, opacity, and short-term thinking, Ziliant Tax is choosing a different path: one built on transparency, accountability, and real-world impact.
B Corp certification recognises businesses that meet the highest standards of social and environmental performance. It’s rigorous. It’s uncompromising. And it reflects exactly how Ziliant Tax believes tax advisory should operate.
“Too often, tax is treated as a technical exercise detached from its consequences,” said Terry Cheesman, CEO at Ziliant Tax. “We disagree. Tax shapes economies, communities, and trust. Becoming a B Corp is our commitment to doing this work responsibly—and visibly.”
Ziliant Tax was assessed across governance, people, clients, community, and environmental impact—embedding these principles into how the firm advises, hires, and grows.
This certification signals a clear stance: clients shouldn’t have to choose between sharp thinking and strong values.
“We’re here to prove you can deliver exceptional tax advice without cutting ethical corners,” added Terry. “In fact, we think that’s the only way to do it properly.”
As part of the global B Corp community, Ziliant Tax joins a movement redefining what good business looks like—and raising expectations of the tax profession in the process.
