Methodology

How Payko calculates your pay

Follow the income, tax and super assumptions behind your estimate, then inspect the calculation checks.

Annual take-home pay

For a full-year Australian resident, the annual model applies the progressive income tax brackets to taxable income, subtracts the low income tax offset where eligible, then calculates Medicare levy, any modelled Medicare levy surcharge and study loan repayment. The selected calculator shows which inputs are included.

Income tax for 2026–27 is nil to $18,200, then 15% to $45,000, 30% to $135,000, 37% to $190,000 and 45% above. Each rate applies only to income within that bracket. Read the legislated brackets.

Annual estimates and payslip withholding

Annual tax liability and employer PAYG withholding are different calculations. Dividing an annual estimate into weeks or fortnights gives a budgeting average. A payslip estimate uses the applicable withholding schedule, pay frequency, tax-free threshold declaration and study loan settings. Bonuses, irregular hours, multiple jobs and part-year work can change the difference.

The main pay calculator offers pay-period comparisons. The annual checks below do not certify every withholding scale or payroll scenario.

Published calculation checks

27 of 27 focused checks passed on 14 September 2026. These run against the annual calculation module used by the site. They cover resident bracket boundaries, the ordinary single Medicare threshold, the lower HELP threshold and a salary package including super. See every input, expected value and actual result.

This is a dated, scoped test run. It is not an independent professional audit or a claim that every possible result has been tested.

Rates and assumptions

Read the rate register and its verification scope.

Limitations that affect your result

Family Medicare reductions need household circumstances and cannot be confirmed from your salary alone. Private hospital cover must qualify for surcharge purposes; extras-only cover does not qualify. Partial-year residency, special working holiday maker treaty treatment, complex benefits, deductions and high-income contribution adjustments can require a separate assessment.

Figures expressed per week or fortnight from annual results assume steady income. Rounding can create small differences. Super is separate from cash take-home pay. Other calculators, including mortgages and stamp duty, have their own assumptions and are outside this annual pay verification.

Using your estimate

Payko provides general numerical estimates. It does not assess your personal financial needs and is not a registered tax agent, accountant or financial adviser. Check significant decisions against the relevant official guidance or a qualified professional.

How the standard deduction is modelled

For 2026–27 resident employment income, Payko starts with the lesser of $1,000 and assessable labour income. Specified work-related deductions reduce that remaining standard amount, not below zero. Other eligible deductions entered separately reduce taxable income in addition. Salary sacrifice reduces assessable cash income and remains part of HELP repayment income where required.

Regular payslip mode does not subtract the annual standard deduction from each pay. It applies the separate PAYG withholding schedules.
