HECS-HELP Australia — Repayment, Indexation, and How It Works

Updated

HECS-HELP is Australia’s income-contingent student loan system, administered by the ATO. Unlike a bank loan, you pay nothing until your income crosses a minimum repayment threshold — and there is no interest, though the debt is indexed to CPI each year. Once your income reaches the threshold, your employer withholds an additional amount from your wages and the ATO applies it to your HECS balance when you lodge your tax return.

This cluster covers everything you need to know about HECS-HELP: the current repayment thresholds and rates, how indexation works and what it cost borrowers in recent years, voluntary repayments, and what happens to your HECS debt if you move overseas.

How HECS-HELP Works

HECS Indexation

  • HECS Indexation Explained — How CPI indexation is applied on 1 June each year, the recent high-indexation years (7.1% in 2023, 4.7% in 2024), and how to interpret the impact on your balance
  • HECS Debt History and Indexation Rates — A year-by-year look at indexation rates and how Australia’s student debt system has changed since 1989

Voluntary Repayments

  • Making Voluntary HECS Repayments — How to make additional payments via BPAY or the ATO, the timing rules, and whether you get a discount (you don’t — the 5% bonus was abolished in 2017)
  • Should You Pay Off HECS Early? — A comparison of paying down HECS versus investing the same money, taking into account indexation, your tax bracket, and opportunity cost
