I've recently started salary sacrificing my super contributions and am aware that this impacts on my HECS/HELP repayments (adjusted taxable income, etc). The ATO website recommends speaking to your employer about taking additional funds from your pay to cover the difference, but when I spoke to my payroll department, they said the can't specifically take funds for HECS/HELP, but they can action an 'additional tax deduction'.
If they take the extra funds as an 'additional tax deduction', am I still at risk of having underpaid my HECS/HELP requirements for the financial year?
Or would this 'additional tax deduction' ultimately be used as part of my compulsory HECS/HELP repayment?
