- Accepts your award or agreement multiplier.
- Shows final annual tax impact, not a payroll withholding quote.
Frequently asked questions
Is overtime taxed at a higher rate?
Overtime is added to annual taxable income and taxed under the same progressive rates. Withholding on a particular payslip can look higher than the final annual outcome.
What overtime multiplier should I use?
Use the multiplier in your modern award, enterprise agreement or employment contract. There is no single multiplier for every worker.
Does the estimate include HELP?
Yes, if selected. It also includes resident income tax, LITO and Medicare levy.
