New personal income tax rates come into effect from 1 July 2018. The top threshold of the 32.5% personal income tax bracket will increase from $87,000 to $90,000. Dovetailing into the tax bracket change is the introduction of the Low and Middle Income Tax Offset for those with taxable incomes up to $125,333. The offset is a non-refundable tax offset that you receive when you lodge your income tax return.
If your annual taxable income is $80,000 in 2018-19, then the personal income tax changes provide an annual tax reduction of $530 per year. If your annual taxable income is $120,000, then the changes give you an annual reduction of $215.
