Payroll Tax Act 2009

If an employer grants a share or option to an employee and the value of the grant of the share or option is not included in the taxable wages of the employer for the financial year in which the share or option was granted, the employer is taken to have elected to treat the wages constituted by the grant of that share or option as being paid or payable on the vesting date.

If an employer grants a share or option to an employee and the value of the grant of the share or option is nil or, if the employer were to elect to treat the date of grant as the relevant day, the wages constituted by the grant would not be liable to payroll tax, the employer is taken to have elected to treat the wages constituted by the grant of that share or option as being paid or payable on the date on which the share or option was granted.
