The practice is particularly suited to clients whose Australian tax affairs are more complex than standard salary-and-wage tax returns. This includes globally mobile individuals, foreign residents, non-residents, overseas property owners, high-income earners, high-net-worth individuals, family groups, clients with complex investment structures, clients with foreign income, clients with Australian rental properties, clients with CGT events and clients with several years of overdue Australian tax returns.
AIMS Australia Tax Accountants assists individuals and families who live overseas but may continue to have Australian tax obligations. This includes overseas Australians, foreign residents and non-residents who own investment properties in Australia, receive Australian rental income, have sold Australian property, have overdue or unlodged Australian tax returns, or need assistance reviewing their Australian tax residency position.
The firm regularly assists with Australian rental property schedules, rental income reporting, allowable rental property deductions, loan interest, council rates, water rates, strata fees, repairs and maintenance, insurance, depreciation, capital works deductions and property manager annual statements.
AIMS Australia Tax Accountants also assists foreign residents and non-residents with Australian investment property tax returns. This may include non-resident rental property tax returns, Australian rental property tax returns for overseas owners, foreign resident capital gains tax issues, foreign resident capital gains withholding, CGT reporting for Australian property sales and prior-year lodgement catch-up.
Where an Australian property has been sold, the firm can assist with reviewing the relevant CGT reporting requirements, purchase and sale documents, settlement statements, ownership history, cost base information, capital improvements, depreciation and capital works history, main residence considerations where relevant, and whether any foreign resident capital gains withholding needs to be considered in the Australian tax return.
AIMS Australia Tax Accountants also assists clients with multiple overdue Australian tax returns and late tax return lodgement. Many clients seek assistance after several years of overdue tax returns, particularly where they have moved overseas, become non-residents, retained an Australian rental property, received foreign income, sold assets or received ATO notices. The firm assists with reviewing the ATO lodgement position, identifying the relevant tax years, reviewing ATO prefill information, reconciling income, preparing prior-year Australian tax returns and addressing ATO lodgement compliance issues where appropriate.

The firm has a structured approach to Australian tax return preparation and complex tax matters. The process usually begins with preliminary scoping to understand the client’s tax years, residency position, income sources, rental property details, CGT events, ATO notices, overdue lodgements, asset structures and available records. Once the matter has been scoped, the firm confirms the proposed engagement, information requirements, professional fees and next steps before work commences.
AIMS Australia Tax Accountants also assists clients who need professional support with ATO correspondence, ATO tax return amendments, ATO objections, private binding ruling applications and prior-year corrections. This may include reviewing whether a previously lodged Australian tax return should be amended, whether omitted income or incorrect deductions need to be corrected, whether CGT has been reported correctly, or whether a tax residency or foreign income issue requires further review.
The firm also assists clients who are unsure whether they are Australian residents or foreign residents for tax purposes. Australian tax residency can affect the treatment of foreign income, Australian rental income, CGT, foreign assets, overseas employment income, foreign pensions and Australian lodgement obligations. Where a client has moved to Australia, left Australia, lives overseas, or has spent time between countries, AIMS Australia Tax Accountants can assist with reviewing the relevant facts and advising on the next steps.
AIMS Australia Tax Accountants works with clients in Australia-wide and overseas. Appointments should be booked in advance, and prospective clients are encouraged to submit an online enquiry before attending either office. This allows the firm to understand the nature of the matter, review the likely scope and advise on the appropriate next steps.

AIMS Australia Tax Accountants does not guarantee refunds, tax savings, penalty remission, ATO outcomes, amendment outcomes, objection outcomes, CGT outcomes or tax residency conclusions. Formal advice and tax return preparation only commence after scope, onboarding and engagement terms have been confirmed.
