Which tax year does this calculator use?+
It uses the Australian resident individual income tax rates for 2026–27, including the 15% rate from $18,201 to $45,000, plus an estimated LITO and basic Medicare levy.
Is this the amount my employer will withhold?+
Not necessarily. PAYG withholding depends on payroll declarations, pay period, HELP debt and ATO withholding schedules. Use the official ATO calculator for payroll withholding.
