Medicare levy surcharge at $100,000
A single person on $100,000 pays no surcharge in 2026-27: the threshold is $105,000 of income for MLS purposes ($5,000 away). Above it, the surcharge starts at 1% of your whole income for anyone without appropriate hospital cover. Check your own position with the MLS calculator.
Superannuation on $100,000
Your employer must pay 12% super guarantee on ordinary time earnings: about $12,000 a year on top of your salary. The 2026-27 concessional contributions cap is $32,500, leaving about $20,500 for salary sacrifice or personal deductible contributions.
Example: sacrificing $5,000 a year into super saves about $1,600 in income tax and Medicare levy. The fund pays $750 contributions tax (15%), so about $4,250 lands in your super while your take-home pay falls by about $3,400. Try your own numbers in the salary sacrifice calculator.

$100,000 as an hourly rate
On a 38-hour week, $100,000 is about $50.61 an hour before tax, or $39.21 an hour after tax and Medicare levy. A casual role would need a higher base rate to match, because casual loading replaces paid leave. Contractors should use the contractor tax calculator, since ABN income has to cover your own super and leave.
Things to watch at $100,000
With a study loan, your compulsory HELP repayment at this income (about $4,571) is a large share of your deductions, and every extra dollar loses about 47% combined. Concessional super contributions save 17 cents per dollar in tax, but they do not reduce HELP repayment income.
