Australia's tax landscape faced a substantial shift as data from the Organisation for Economic Cooperation and Development (OECD) revealed a notable spike in the country's average tax rate, positioning it as the top performer in average tax rate increase within the group of developed nations. The surge, marked at 7.6%, was largely attributed to the termination of the Low and Middle Income Tax Offset (LMITO) – colloquially referred to as the Lamington – which had a considerable impact on low- and middle-income individuals, as highlighted by ABC News earlier in the year. This change, coupled with the phenomenon of bracket creep, where inflation-induced pay increases pushed individuals into higher tax brackets, resulted in a substantial increase in tax burdens, especially for those earning two-thirds of the average wage.
The repercussions of these tax policy alterations became evident in data illustrating the altered income tax burdens for Australians earning various proportions of the average income. For instance, individuals earning two-thirds of the average wage witnessed a rise in their tax burden compared to the previous year. Despite a rise in nominal wages, the increase failed to translate into significant financial gains due to inflation's impact on the cost of living, undermining the real purchasing power of individuals. The OECD data further demonstrated that even individuals earning 167% of the average wage experienced an upsurge in their tax burden, albeit being marginally better off financially considering the current economic scenario marked by inflation and rising costs of living.
Moreover, the analysis of Australia's tax system dynamics extended to upcoming changes, such as the Stage 3 tax cuts set to be implemented, designed to offer varying degrees of tax relief to different income groups. While initial tax cut plans favored higher income earners, subsequent adjustments by the government resulted in revised benefits aimed at different income brackets. Additionally, discussions on the country's tax regime delved into international comparisons, with Australia's average income tax rate being scrutinized in relation to other OECD countries, prompting a deeper examination of tax to GDP ratios to provide a more comprehensive understanding of Australia's tax structure and its positioning within the global context.
