About Us

Our History

MST Tax merged with Tarrants Accountants & Business Advisors during 2015. Tarrants was a long standing accounting and tax advisory practice within the Illawarra community, being started by Ross Tarrant in 1988 as a sole practitioner at Corrimal and Balgownie. His family members joined him in the business over the years. Together they grew the business providing tax and accounting services to many of the Illawarra’s small businesses and to individuals working in a myriad of industries and occupations. Over the next 30 years, 3 generations of Tarrants worked in the business accumulating over 100 years of service to the business. The business outgrew its Balgownie premises and moved to its current office in the heart of Wollongong’s CBD during 2000 where MST Tax continues to operate from.

MST Tax is pleased to continue to have the involvement of the Tarrant family within its business. Ross Tarrant (Consultant) and Lara Tarrant (Tax and Superannuation advisor) continue to provide services to our clients. Together with our other staff led by Stefanie Seco, their experience and knowledge in a rapidly changing tax and business environment is important. That experience and knowledge allows us to continue to deliver advice and services that are timely, relevant and in accord with the relevant laws.

MST Tax is proud to be an employer of individuals of all ages and providing employment opportunities in the Illawarra for individuals with a diverse range of technical and other skills.

Tarrants, big enough to trust, small enough to care.
