Tax on a $100,000 Salary in Australia (2025-26)
On a $100,000 salary in 2025-26 you pay $22,788 in tax and Medicare levy and keep $77,212 — the full breakdown, plus what a raise to $110k nets.
On a $100,000 salary in 2025-26 you pay $20,788 in income tax plus $2,000 Medicare levy, leaving take-home pay of $77,212. That's about $6,434 a month, or roughly $2,970 a fortnight.
Here's where every dollar goes, why your real tax rate is lower than the brackets suggest, and what a raise to $110k actually puts in your pocket.
Watching $100,000 climb the staircase
Australia's tax system works like a staircase: your income is sliced into chunks, and each chunk pays only the rate of its step. Nothing gets dragged up to a higher rate because you crossed a line. Here's $100,000, step by step:
- First $18,200 at 0% = $0 (the tax-free threshold everyone gets)
- $18,201 to $45,000 ($26,800) at 16% = $4,288
- $45,001 to $100,000 ($55,000) at 30% = $16,500
- Income tax total = $20,788
- Medicare levy (a flat 2% that helps fund public healthcare) = $2,000
- Total tax $22,788 — take-home pay $77,212
Your real rate isn't 30%
On $100,000, your marginal rate (the tax rate on your last dollar) is 30%, plus the 2% levy. But your effective rate — the average across every dollar — is just 22.8% including Medicare, because the first $18,200 paid nothing and the next $26,800 paid only 16%.
The marginal rate is what matters for decisions. Overtime, a bonus or a side gig is taxed at 32 cents per extra dollar — and every dollar of deductions (work costs the ATO lets you subtract) saves you exactly 32 cents too.
⚡Quick win
At $100k, every $100 of legitimate deductions puts $32 back in your pocket. A $1,000 claim for work-from-home costs, tools or subscriptions is a $320 refund boost.
The $110k question
A raise from $100,000 to $110,000 won't "all get taxed away". On $110,000 you'd pay $23,788 income tax plus $2,200 Medicare levy, for take-home pay of $84,012. Against $77,212, your $10,000 raise nets you $6,800 — you keep 68 cents of every new dollar.
Only the new dollars pay the 30% rate plus levy; everything underneath keeps its old, cheaper rates. A raise in this bracket can never leave you worse off. Take the raise.
The money you forgot you're earning
On top of your $100,000, your employer must pay 12% super guarantee — $12,000 a year into your super fund (your locked-until-retirement investment account). It's paid on top of your salary, so your true package is $112,000.
One more line to watch: a HECS-HELP debt (your uni loan). Repayments kick in once you earn over $54,435, so at $100,000 a compulsory repayment comes out at tax time on top of the figures above. Payroll withholds extra to cover it — but only if you've told them the debt exists.
💡Reality check
Job ads mixing "package" and "salary" can hide a $12,000 difference. A "$100k package" including super is really a $89,286 salary. Always ask which one they mean.

These figures assume a resident with no deductions and no HECS. Deductions shrink the tax, a student loan grows it, and salary sacrificing (paying for extra super straight from pre-tax pay) reshuffles the whole picture.
