Australia taxes individuals in slices. Your taxable income is divided at fixed thresholds and each slice is taxed at that slice’s rate, so the first $18,200 is always free of tax no matter what you earn in total.
This is why a pay rise cannot leave you worse off. Only the income above the next threshold pays the higher rate, and every dollar below it keeps the rate it always had.
Two numbers describe your position and they are easy to confuse. The marginal rate is what the next dollar attracts. The effective rate is the total tax you pay divided by everything you earned.
The gap between them is the whole point of a bracket system. Because the slices below your top slice are taxed lightly, the average is always well under the top rate you can quote.
Residents for tax purposes pay nothing on the first $18,200. Foreign residents get no tax free threshold and pay from the first dollar, though they are not liable for the Medicare levy.
Working holiday makers are taxed on their own schedule regardless of how long they stay. Residency for tax is not the same as your visa status, and the ATO applies its own tests, so check which schedule applies before you assume.
An offset reduces the tax calculated from the brackets. It does not reduce your taxable income, which is why an offset worth $700 is worth $700 to everyone who can use it, rather than being worth more at a higher rate.
The low income tax offset phases out as income rises. That phase out is an invisible extra rate over the range where it applies, and it is the main reason the effective rate climbs faster than the bracket table suggests between $37,500 and $66,000.
A second employer withholds as though that job were your only income, so the tax free threshold can be applied twice during the year. Nothing is wrong with the brackets. The shortfall simply appears at the return.
Not through the income tax brackets. Only the income above a threshold pays the higher rate. Means tested payments and repayment thresholds can move at the same time, so check those separately if you receive them.
About 24 per cent including the Medicare levy for a resident with no offsets or deductions, against a marginal rate of 32 per cent.
No. The levy of 2 per cent is calculated separately on taxable income and then added, which is why the practical marginal rate is 2 points above the bracket rate for most residents.
To income earned from 1 July 2026 to 30 June 2027. Income from earlier years keeps the rates of the year it was earned in.
