About Tax Owl Limited

Stephen Diedericks Tax Owl Limited is a Tax Advisory, Trust and Asset Protection Services firm founded by Stephen Diedericks.

Stephen’s journey to accounting starts from his humble roots in Cape Town, South Africa. He obtained a scholarship from a South African company to study accounting. He relocated to Australia to complete his accounting studies (later relocating to New Zealand – yes, he followed a girl, his wife). While studying, he developed a passion for taxation. When Stephen started working full time, he also studied law, which complemented his work in tax. His accounting and law qualifications, as well as his practical experience, have helped him reach such a high level of tax knowledge and understanding.


Ruth Ja Originally from Palmerston North, Ruth moved to Havelock North with her parents in 1980. After finishing High School, she worked for a local Law firm in Hastings, moving on after a couple of years to the Banking and Finance industries.

Moving overseas in 1992, Ruth and her husband spent time working with various not-for-profit organizations and were instrumental in obtaining relief aid for the victims of Hurricane Andrew. Upon returning to New Zealand, Ruth home-schooled their three sons, while assisting her husband with his media business, managing the accounts. During this time, she also began working in a Customer Service roll for a local business, moving onto a Compliance Manager position, encompassing Food and Safety, and Health & Safety. Ruth enjoys taking her dog for walks, theatre, Israeli Folk dancing, and delving into a good book. Her passion for the English language also means assisting others (including small children) to learn to read and teaching English as a second language, helping people gain fluency and understanding.
