If the commission is for a specific single pay period and it's their only source of income, should it not be computed using the standard PAYG withholding tax table? And not the PAYG on Schedule 5? Please refer to the ATO statement below:
If a commission, bonus or similar payment relates to work your employee performed for more than one pay period (or for an undefined period), calculate withholding by applying either Method A or Method B(ii).
Do not use this schedule for payments for a single pay period.
If the commission, bonus or similar payment relates to work your employee performed in a single pay period (for example, a week, a fortnight or a month) the amount is added to all their other earnings for the current period. Withholding is then calculated using the standard PAYG withholding tax tables.
