Which assumption could change the answer most.
When to stop using a rough estimate and ask payroll, the ATO or a qualified adviser.
Withholding is an estimate
Payroll withholds based on declarations, pay frequency and tables. It is designed to approximate annual tax.
Tax return reconciles the year
Other income, deductions, offsets and repayment income can change the final result.
Payslip differences are normal
A calculator can estimate take-home pay, but it cannot know every tax-return item.

Check the financial year.
Confirm whether super is included or added on top.
Check HELP debt and tax residency settings.
Compare weekly, fortnightly and monthly cashflow.
Common questions
Is PAYG withholding the same as my final tax?
Not always. It is reconciled through the tax return.
Can withholding be too high?
Yes. Over-withholding may lead to a refund, while under-withholding may lead to tax payable.
