Clayton Utz is pleased to announce the appointment of tax litigator and adviser Rimma Miller as a partner in our Sydney office, further strengthening the firm’s national tax practice.

Rimma joins Clayton Utz from MinterEllison, where she was a partner in the firm’s tax controversy practice.

With more than 25 years’ experience, Rimma has built a practice spanning complex tax disputes, tax advisory and strategic risk management, including advising and representing large corporates across diverse industries, including resources, energy, technology, natural sciences and financial services.

Rimma spent more than a decade earlier in her career as a senior litigator with the Australian Taxation Office, giving her deep insight into regulatory strategy, technical interpretation and dispute management.

Clayton Utz Chief Executive Partner Emma Covacevich said Rimma’s appointment represents a strategic investment in the firm’s disputes and tax capabilities at a time of increasing scrutiny and complexity in the tax landscape.

“Rimma is one of Australia’s leading tax litigators, with an exceptional track record in complex, high-value disputes," Ms Covacevich said. "Her move to Clayton Utz is a significant milestone in the continued growth of our tax practice.”

“Clients are facing unprecedented levels of regulatory focus and increasingly sophisticated revenue authority activity. Rimma’s depth of experience – particularly her rare combination of ATO and private practice expertise – will be invaluable to our clients navigating this environment.”

Ms Covacevich added: “We are committed to building a pre-eminent tax disputes capability nationally. Rimma’s appointment complements the outstanding work of our broader disputes team, and positions us strongly for continued growth.”
