Salary sacrificing is a great way to secure your financial future. By giving up a nominated amount of your regular salary you reduce the amount of tax you pay on your income (by paying a lower rate on the amount sacrificed to your super) as well as build up more wealth in preparation for your retirement. When you should start depends on how much of your regular income you can afford to give up, your current superannuation balance and how close you are to retirement. Your payroll department will be able to assist you with setting up salary sacrificing.
