That's because the employer pays the FBT if applicable (ie. they lodge an annual FBT return).It doesn't seem to mention FBT payable and it didn't ask whether the car is for private or business use.
The novated lease agreement is between three parties - you, your employer and the leasing company.
My understanding, as simply put as I can, is that the employer makes the lease payments on behalf of the employee, makes any adjustments for FBT and then deducts, the adjusted repayments from the employee's cash salary. That's why they call it a salary package.
The individual doesn't claim any expenses in their tax return.
