Clarity over Complexity
Your entrusted business advisor

About ACTA
ACTA is the abbreviation of AC Tax Advisory. It was founded by our Managing Director, Agnes Cheung, a seasoned tax professional with extensive experience advising multinational groups, investment funds, family offices, and high‑net‑worth individuals on complex tax and regulatory matters.
​
Before establishing the firm, Agnes held senior roles in leading professional services firms, where she worked closely with business owners, investors, and global finance teams on structuring, cross‑border tax planning, and regulatory compliance. This experience provided first‑hand insight into the challenges clients face when navigating evolving tax rules, commercial pressures, and regulatory expectations.
​
The firm was established with a clear purpose: to provide practical, commercially‑minded tax advice that goes beyond technical compliance. We believe effective tax advisory should support business growth, protect long‑term value, and stand up to regulatory scrutiny — without unnecessary complexity.
​
As an independent boutique, we offer senior‑level attention, flexibility, and solutions tailored to each client’s specific commercial context. Just as our logo depicts a dove flying freely in a clear blue sky, our approach to tax advisory is centred on:
-
Trust and integrity
-
Clarity over complexity
-
Fresh, thoughtful perspectives
-
Helping clients move forward with confidence and peace of mind
​
We believe sound tax advice should not feel overwhelming. Instead, it should enable better decisions, protect value, and allow clients to focus on what matters most—their business and long‑term goals.
