ABOUT THE FIRM

About AIMS Australia Tax Accountants

Established in Melbourne in 2012, AIMS Australia Tax Accountants was founded with a clear purpose: to provide careful, technically focused Australian tax support for clients whose circumstances extend beyond a standard tax return.

Established in Melbourne in 2012, AIMS Australia Tax Accountants was founded to provide careful, technically focused Australian tax support for clients whose circumstances extend beyond a standard tax return.

The firm began as a CPA public practice and has evolved into a specialist Australian tax practice known for work with expatriates, foreign residents, non-residents, Australian property investors and clients with cross-border Australian tax obligations.

Led by Nika Widanage, FCPA and Registered Tax Agent, AIMS Australia Tax Accountants assists clients whose tax affairs require detailed analysis, supporting evidence and careful interpretation of Australian tax law.

The firm’s approach is structured and evidence-based. Before adopting a tax position, AIMS Australia Tax Accountants reviews the client’s residency history, income sources, asset ownership, supporting records, prior lodgements and relevant ATO correspondence.

AIMS Australia Tax Accountants is not a generalist accounting firm. Its focus is specialist Australian tax work for clients in Australia and overseas whose personal tax affairs involve cross-border complexity, Australian property, residency changes, high-value assets or prior-year compliance issues.
