PAYG Withholding vs Income Tax
Why payroll withholding and final income tax are related but not always identical.
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.
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.
