Salary Sacrifice on novated lease
	
	
		Question you need to ask yourself does she actually need a brand new car, if she don't then novated lease ain't worth doing and your better off financially putting the cost of the novated lease into additional salary sacrifice superannuation contributions especially given changes to tax laws on superannuation.
 
If she does need a car and a new one then there are several options you need to consider, such as at end of lease period are you keeping car or getting another one under a new novate lease. Another option is taking out insurance to cover payments on lease if she loses or leaves work as well as covering balloon payment at end of 3 year lease period which depending on car lease arrangements could be 50% of new value, so in 3 years you need to find another $25,000 for example on $50,000 car. SOme companies have guaranteed buyback prices to pay for end of lease arrangements but of course they are building cost into slightly higher monthly payments.
 
All you are really doing is averaging your salary between FBT tax rate and PAYE tax rate and if on higher PAYE rates you make saving as FBT rate lower. How much you save depends on your salary and FBT rules on things like car business private use and km travelled per year etc.
 
You can go to ATO tax site and get information to do some quick calculations for yourself, also definitely talk to accountant and in particualr pay attention to lease costs and balloon payments as well as the monthly charges. 
 
Shop around for deals too on salary packaging there a few companies competing to provide the service to employees, depending on what your wife employer is doing in relation to managing the salary packaging options internal or outsourcing them to financial service companies.
 
As i said if she don't need a new car don't do it, super it instead
