How to Use a Salary Tax Calculator Australia to Find Your Take-Home Pay

How Your Fortnightly Pay Changes: Tax Brackets, Medicare Levy, and Super

When you look at your payslip, the number that lands in your bank account is your take-home pay. It is your gross salary minus income tax, the Medicare levy, and any other deductions. To get a clear picture, you can use a salary tax calculator Australia – the Australian Taxation Office provides a free tool that works out the exact amount your employer should withhold.

The 2026–27 Tax Brackets for Australian Residents

The ATO publishes the resident tax rates each year. For 2026–27, the rates are:

• $0 – $18,200: Nil tax
• $18,201 – $45,000: 15c for each dollar over $18,200
• $45,001 – $135,000: $4,020 plus 30c for each dollar over $45,000
• $135,001 – $190,000: $31,020 plus 37c for each dollar over $135,000
• $190,001 and over: $51,370 plus 45c for each dollar over $190,000

These rates do not include the Medicare levy (2%) or the Medicare levy surcharge. The tax-free threshold of $18,200 means your first $18,200 of income is tax-free. If you earn $52,255 (the national minimum wage annualised), your tax is calculated as: $4,020 + 30% of ($52,255 – $45,000) = $4,020 + $2,176.50 = $6,196.50. Then add the Medicare levy of 2% of $52,255 = $1,045.10. Your total tax and levy is $7,241.60, leaving a take-home of about $45,013.40 per year, or roughly $1,731 per fortnight.

The Medicare Levy: What You Pay

The Medicare levy is a flat 2% of your taxable income for most full-time workers. However, low-income earners may be exempt or pay a reduced rate. The latest ATO single-person thresholds are $28,011 and $35,013. If your taxable income is below $28,011, you pay no Medicare levy. If it is between $28,011 and $35,013, the levy is phased in at 10c per dollar over $28,011. Above $35,013, you pay the full 2%. For a full-time worker on the minimum wage ($52,255), you are well above the upper threshold, so you pay the full 2%.

Super Guarantee and Take-Home Pay

From 1 July 2026, the super guarantee rate is 12% of your ordinary time earnings, up to a maximum contribution base of $270,830. Super is paid by your employer on top of your salary – it is not deducted from your take-home pay unless your contract is structured as a total remuneration package. When you see a job ad that says "$80,000 plus super", the $80,000 is your gross salary, and super is extra. Your take-home is calculated from that $80,000. If the ad says "$80,000 including super", then your gross salary is lower (about $71,429) and super is deducted from that amount.

Using the ATO's Salary Tax Calculator Australia

The ATO's Tax withheld calculator is designed for employers but you can use it to estimate your own withholding. Enter your gross pay per period (weekly, fortnightly, or monthly), your residency status, and whether you claim the tax-free threshold. The calculator will show the amount to withhold, your net pay, and any additional withholding for study and training loans. It applies the 2026–27 rates and includes the Medicare levy. For a simpler version, the Moneysmart Income tax calculator gives you your tax, Medicare levy, and take-home pay based on your annual taxable income.

What Changes Your Fortnightly Take-Home

Your fortnightly pay changes when you move into a higher tax bracket. For example, if you earn $80,000 a year, your tax bracket is $45,001–$135,000, so you pay 30c for each dollar over $45,000 plus the base $4,020. If you get a raise to $100,000, you stay in the same bracket but pay more tax at 30c per dollar. If you cross $135,000, you move to the 37% bracket. The Medicare levy stays at 2% unless your income drops below the thresholds. Super does not affect your take-home unless you salary sacrifice into super, which reduces your taxable income and therefore your tax.

Benchmarks to Compare Your Pay

Fair Work sets the national minimum wage at $26.44 per hour and $1,004.90 per week (from 1 July 2026). The ABS reports average weekly total earnings for all employees at $1,579.20 (May 2026, seasonally adjusted), and for full-time adult ordinary time earnings at $2,083.70 per week. These benchmarks help you see where your salary sits. Use our Take-home pay guide to see how these figures translate into after-tax amounts.

Final Thoughts

A salary tax calculator Australia is the best way to get a reliable estimate of your after-tax income. Remember that the ATO's calculator and the Moneysmart calculator are estimates only – they do not account for HELP/HECS repayments, the Medicare levy surcharge, salary sacrifice, or payroll tax-table rounding. For a precise figure, check your payslip or ask your payroll officer. For more details on tax and Medicare, see our Tax and Medicare page.
