I am a Chartered Tax Adviser (CTA), Member of the Association of Taxation Technicians (ATT), and an Independent Certified Practising Accountant (ICPA).
We have since incorporated as T4 Tax Limited in 2004.
I qualified as a member of the Association of Taxation Technicians in 1989 and then also in what is now known at the “Chartered Institute of Taxation” in 1990.
Over the last 30 years I have dealt with a very wide range of tax and accounting issues for both small businesses and medium size businesses.
I have a wide range of experience in dealing with people from all walks of life from the rich & famous to the rest of us mere morals.
My goal is to treat everyone equally and give practical, efficient & effective advice to all my clients.
