I have a new employee who is 15 years old (Australian citizen). On the TFN form, he ticked the option: "I am claiming an exemption because I am under 18 years and do not earn enough to pay tax" , and also he ticked " YES" to claim the tax-free threshold from this payer. I have entered the TFN exemption code 333 333 333. My question is which tax setting code should I select for this situation? Should it be 2-TFT, 4-No TFNr or 8-No Tax and put tax 0% ? Thank you.
