About Us

Tax, Accounting and Super Centre began in Mount Isa as Steve Williams and Co., which then became known as Tax, Accounting and Super Centre. This shortens to TASC, a play on the word "task". We enjoy and respect what we do and keep it fun, friendly and real.

Our success has come from our local knowledge, identifying and understanding individual needs of our clients and providing them with prompt service. We have always worked outside the spectrum of the typical accounting practise by recognising and prioritising our client needs. At TASC we do not see our clients as numbers, we see them as a person with a dream and a vision to be financially secure and at TASC our focus is to help our clients achieve their dreams.

Our Mission

Tax, Accounting and Super Centre's mission is to build a successful company by providing a quality affordable service available to everyday people. We will never compromise our ethics in the pursuit of profit and as such, expect to build a company founded on the best moral conduct for the benefit of not only the clients but also the community in which we operate.

Our Vision
