To check your employees Tax Fille Number
Go to Employee Details, select the employee.
The Tax File Number is in Payments, Tax.
The TFN is usually entered without spaces. For STP to work, all employees must have a valid TFN or ABN. If an employee does not have a TFN, in the Employee Details, Payments, Tax, enter 111111111 as the TFN. The ATO allows 28 days before the employee has to give a valid TFN. After the 28 Days, if the employee still does not supply a TFN then change the TFN to 000000000 and change the employee's tax scale to 04. If your employee is under 18 and work less than 30 hours a week, use 333333333. If your employee is an Australian Government Pensioner, use 444444444.
