Addy v Commissioner of Taxation

In the case of Addy v Commissioner of Taxation, the applicant, a citizen of the United Kingdom, challenged the decision of the respondent regarding her income tax assessment for the 2017 financial year. The applicant had arrived in Australia on a working holiday visa and had lived in Australia for nearly two years, raising questions about her residency status and the application of Australian tax laws. The court was tasked with determining whether the applicant was a resident of Australia under section 6 of the Income Tax Assessment Act 1936 (Cth), and whether the tax rates applied to working holiday makers, as outlined in Part III of Schedule 7 to the Income Tax Rates Act 1986 (Cth), were more burdensome than those applicable to Australian nationals in similar circumstances.

The court examined the interpretation of the term "resident" under the Income Tax Assessment Act 1936 (Cth), focusing on the "usual place of abode" exception for individuals present in Australia for more than half a year. The court also addressed the application of the Australia-UK Double Taxation Agreement, specifically Article 25, which stipulates that nationals of the contracting states should not be taxed more burdensomely than their own nationals in the same circumstances. The court had to interpret this provision in light of the International Tax Agreements Act 1953 (Cth) and the Vienna Convention on the Law of Treaties. Additionally, the court considered whether the taxation of the applicant as a working holiday maker constituted discrimination based on nationality, as prohibited by Article 25.

The court found that the Double Taxation Agreement, given domestic effect by the International Tax Agreements Act 1953 (Cth), took precedence over the Australian tax laws to the extent of any inconsistency. The court applied settled principles of treaty interpretation, emphasizing the importance of the text, context, object, and purpose of the treaty provisions. The court held that the term "national" under Article 3(1)(l) of the Double Taxation Agreement meant different things in relation to the UK and Australia, and that the applicant was subject to UK law rather than Australian law for taxation purposes. The court determined that the tax rates applied to working holiday makers did not amount to a more burdensome taxation than that applied to Australian nationals in similar circumstances, thus no discrimination based on nationality had occurred.

The court allowed the appeal, set aside the respondent's objection decision, and ordered the respondent to make an amended assessment. The applicant's objection was allowed, and the matter was remitted to the respondent for the appropriate tax assessment, considering the applicant's residency status and the applicable tax rates. The court granted leave to apply for further directions regarding the basis of the amended assessment and made no order as to costs.
