After an initial eight-year stint with the firm, Sanyin Geljic re-joined Koustas + Co in 2014 as Taxation Manager.  In July 2018, Sanyin was appointed Principal, in our Taxation division.

He brings broad experience to the firm in areas of compliance accounting, business advisory and tax consulting for the SME (small and medium enterprises) market. He currently focuses on advising clients and assisting them with income tax, capital gains, fringe benefits, business structuring, superannuation and retirement-planning matters.

Before joining Koustas + Co, Sanyin was a sales associate at a large Telco where he was recognised for achieving outstanding sales results. Prior to this, he spent several years studying, having moved to Australia from Bosnia and Herzegovina in December 2000. He undertook English language classes and a Diploma in Business Marketing, which eventually led him to complete an accounting degree.

Sanyin’s commercial acumen and involvement in sales and marketing activities, while employed in Bosnia and Herzegovina, provided him with a solid background in helping companies maximise their business performance. While employed at the local subsidiaries of American and Italian conglomerates, he helped these international companies develop and expand their market share in the region. He also contributed to improving their profitability and customer service. Before departing for Australia, Sanyin also established a family-owned business which gave him an insight into managing small businesses.

Having graduated with a Bachelor of Business degree (with an Accounting major) at Monash University, he later attained his Chartered Accountancy qualification. Sanyin has a Master of Applied Taxation from UNSW which was prompted by his desire to continue to add value to his clients’ businesses, and to assist them in complex tax matters.

Sanyin is also fluent in Bosnian, Croatian and Serbian languages.
