The $45,000 Bracket

This is the biggest marginal rate jump in the Australian tax system — from 16 cents to 30 cents per dollar. However, only income above $45,000 is taxed at 30%. On a $50,000 salary, only $5,000 is taxed at the higher rate, adding $1,500 to your tax bill compared to the 16% rate.

Tax tips at this income level

Salary sacrifice into super to reduce taxable income

Sacrificing salary into super is taxed at 15% inside the fund — a saving of 15 cents per dollar compared to your 30% marginal rate. Even modest contributions make a meaningful difference at this bracket. Use calculator →

Claim all work-related deductions

Every $1 in legitimate work-related deductions (home office, tools, professional development) saves you 30 cents in tax at this bracket — plus reduces your Medicare levy base.

Check your HELP repayment rate

If you have a HELP debt, repayments are compulsory above $67,000 repayment income. Below that threshold, no compulsory repayments apply. Use calculator →

Review private health insurance

The Medicare Levy Surcharge applies to singles earning over $101,000 without private hospital cover. At $45,000 you are well below this threshold, so MLS is not a concern at this income level.

Frequently asked questions

How much more tax do I pay when I cross $45,000?
Each dollar above $45,000 is taxed at 30% instead of 16%, so you pay an extra 14 cents per dollar. On a $50,000 salary, the additional $5,000 above $45,000 costs $1,500 in tax at the higher rate (compared to $800 at the lower rate).
Is the $45,000 threshold different for part-year residents?
The same brackets apply. However, if you were not an Australian resident for the full year, your tax-free threshold may be reduced proportionally. The ATO part-year residency rules apply — consult a tax agent for your specific situation.
How can I reduce my tax if I'm just above $45,000?
Salary sacrificing into super is the most effective strategy. Contributions to super are taxed at 15% instead of 30%, saving 15 cents per dollar. Work-related deductions also reduce your taxable income below $45,000 if they are large enough.
