About Us


Tax Assure was founded in 2015 by Terry Brown and Michael Moon, after recognising a clear need from their legal and consulting clients for expert assistance with outstanding tax debts.

In 2019 they were joined as a fellow director by experienced lawyer and business advisor Olga Koskie, who shared their vision for providing a specialist, expert tax debt service to Australian business owners.

Their combined 75+ years of business, legal, tax and consulting experience comes together to create a true powerhouse; without doubt the country’s most experienced tax debt management and advisory service.
