If you’re a property owner in Australia, the term mill levy might sound like something out of a tax accountant’s handbook. But as councils and state governments look for ways to fund local services in 2025, understanding how mill levies work—and how they affect your rates—could help you budget smarter and even challenge unexpected increases.
