Calculation Methodology & Sources

What the calculator estimates

Income tax	Estimated from the selected financial year and residency setting using Australian individual income-tax rates and thresholds.
Medicare levy	Estimated for applicable scenarios. Actual liability can differ because levy reductions, exemptions, family thresholds and the Medicare levy surcharge depend on personal circumstances not fully captured by a simple salary calculator.
Superannuation	Super is editable. FY2026–27 uses 12% as the standard employer super guarantee reference rate unless you enter a different contribution rate or package structure.
HELP / HECS	An optional estimate of compulsory study-loan repayments is included when selected. Actual compulsory repayments use repayment income and can differ from taxable income.
Pay frequencies	Annual estimated results are converted into monthly, fortnightly, weekly or hourly views for comparison and planning.

Current and future financial years

FY2026–27: the resident tax-rate setting reflects the legislated reduction of the first marginal rate above the tax-free threshold to 15% from 1 July 2026.

FY2027–28: this future-year option reflects the legislated reduction of that first marginal rate to 14% from 1 July 2027. Future estimates should be treated as planning figures because other thresholds, offsets or policy settings can change.

Official sources

We review official Australian Government and Australian Taxation Office material when maintaining the calculator. Key references include:

• ATO — personal income tax: new tax cuts for every Australian taxpayer
• ATO — 2026 PAYG withholding tax tables
• ATO — Payday Super and 12% super guarantee information
• ATO — study and training loan compulsory repayment information

Assumptions & limitations

• Results are estimates for general information and salary planning, not financial or taxation advice.
• The calculator does not model every deduction, tax offset, family circumstance, private-health setting, fringe benefit, investment loss or payroll arrangement.
• Medicare and HELP/HECS outcomes can depend on income definitions and circumstances beyond the salary figure entered.
• Employer payroll withholding and your final tax-return liability may differ from these estimates.
• Future financial-year settings reflect legislation available at the review date and may require updates if rules change.
