About Mastin Harris Accountants

Practical accountants who look beyond the numbers to deliver clarity, control and progress.

Mastin Harris Accountants is a Victorian accounting firm focused on helping small business owners, property investors, SMSF trustees and families make better decisions. We look at the full picture – structure, tax, cashflow and risk – so your accounting work actually supports your long-term goals instead of being just an annual compliance exercise.

Our role is to give you clarity around your position, help you stay in control of your obligations and support real progress over time. That might mean reducing avoidable tax, tidying up structures, planning for a future sale or simply giving you a clearer understanding of “what’s going on” so you can move forward with more confidence.

Our philosophy

  • Clear, straightforward advice in plain English
  • No last-minute surprises at tax time wherever we can avoid them
  • Focus on long-term wealth, protection and retirement, not just this year’s refund
  • We work with your other advisers – lawyers, mortgage brokers and financial advisers – not in a silo
  • Practical recommendations that you can actually implement, at your own pace

The people behind the numbers

Clients work with real people who know their situation, not a different face every year. We value long-term relationships, continuity and steady, calm guidance when things get busy or uncertain. You will deal with someone who understands your history, your structures and your goals – not just this year’s form.

Over time, that familiarity lets us spot patterns, highlight risks earlier and suggest opportunities that a once-off tax return service is likely to miss.
