Direct answer
This tool applies the ATO Schedule 1 coefficients effective 1 July 2026. It first converts the pay to a weekly equivalent, adds 99 cents to whole-dollar weekly earnings, applies the relevant coefficient row and rounds the withholding to the nearest dollar.
Calculate Australian weekly, fortnightly or monthly PAYG withholding from the ATO coefficients effective 1 July 2026, with optional study-loan withholding.

Formula and 2026-27 method
Weekly withholding y = a × (whole weekly earnings + 0.99) - b, rounded to the nearest dollar; fortnightly and monthly results use the ATO period conversion.
The calculation is versioned for the Australian 2026-27 financial year. The result panel keeps the period and source status visible so a value is not detached from the rules that produced it.
To compare this result with another relevant method, open the Australian Wage Calculator. Calculate Australian take-home pay for 2026-27 from annual, monthly, fortnightly, weekly or hourly wages, including salary packages with super, income tax, Medicare levy and HELP.
Worked Australian example
At AUD 538 weekly with the tax-free threshold claimed and no study-loan withholding, the official Scale 2 reference result is AUD 27.
Working precision is retained through the method. Displayed currency is rounded only at the final output unless the ATO payroll schedule itself requires whole-dollar rounding.
How to interpret the result
Main boundary: It does not model every payroll adjustment, including Medicare variation declarations, tax offsets, working-holiday makers or bespoke payroll categories. The 53-week/27-fortnight option uses only the ATO additional-withholding table.
Keep gross pay, tax liability, payroll withholding, Medicare, study-loan repayments, super and employment entitlements separate. They answer different questions even when they appear on the same payslip.
What this CalculatorGeek version makes explicit
- The exact Australian financial year and effective date.
- The difference between annual tax liability and pay-run withholding where relevant.
- Super paid on top versus included in a package where relevant.
- Formula components, rounding, limitations and source links beside the result.
- Distinct next-step calculators instead of duplicate thin pages for weekly, fortnightly and take-home wording.

Frequently asked questions
Is this Australian PAYG Withholding Calculator current?
The method is versioned for 2026-27 and the listed primary sources were checked 2026-10-15. Recheck the page after a law, threshold, award or tax-table update.
Is this the same as my payslip or tax return?
Not automatically. It does not model every payroll adjustment, including Medicare variation declarations, tax offsets, working-holiday makers or bespoke payroll categories. The 53-week/27-fortnight option uses only the ATO additional-withholding table.
Can I change the result to another currency?
No. Statutory Australian inputs and results stay in AUD so exchange-rate conversion cannot be mistaken for an Australian tax calculation.
Can I verify the answer?
Yes. The formula, worked example, calculation bridge, model version and primary sources are visible on the page.
