“When I provide clients with a better result than they had hoped for… That’s when I love my job. 

Jonathon Larosa

Director, Tax Services

Jonathon’s passion for taxation, paired with business knowledge gained through over fourteen years experience working with many different clients, evokes confidence within colleagues and clients alike.

A keen traveller with a love of adventure, Jonathon brings the same enthusiasm he has for life to his work environment. “Working with business clients in their growth phase is truly exciting,” he says. “Understanding a business and solving complex tax issues in both local and international markets is particularly rewarding. You become part of that business and have a vested interest to see it reach its potential and grow beyond it.”

Another area Jonathan is active in is helping startup technology businesses. Ensuring the most effective structures and access to tax concessions which gives them the best financial position to build their business, is both a professional and personal reward.

For a number of years, Jonathon lectured for the Taxation Institute’s Applied Tax (now CTA 2 Advanced) Program. His ongoing commitment to solving technical tax matters makes Jonathon a valuable asset not just to his clients but to the larger William Buck team that look to him for his specialist knowledge.

Whether it be through transaction planning or ordinary taxation compliance, Jonathon’s focus is always on helping his clients achieve their ultimate commercial goals.
