What HECS-HELP is
HECS-HELP is the Australian government's income-contingent loan scheme for eligible higher education students. Rather than paying tuition fees upfront, eligible students can defer the cost and repay it later through the tax system once their income reaches a certain threshold.
The scheme was originally called HECS (Higher Education Contribution Scheme), introduced in 1989. It has since been expanded and renamed. Today, HECS-HELP refers to loans for Commonwealth-supported students at universities and other providers. A separate loan product, FEE-HELP, covers full-fee-paying students and some other courses.
Unlike most loans, HECS-HELP does not charge interest. Instead, the debt is indexed to the Consumer Price Index (CPI) each year, which adjusts the balance to maintain its real value. In most years, this indexation is modest. In high-inflation years, it can be significant.
How repayments work
Repayments are not a fixed monthly amount. They are calculated as a percentage of your income and collected through the tax system, either via PAYG withholding throughout the year or as an assessment when you lodge your tax return.
The repayment rate applies to your Repayment Income — broadly your taxable income plus reportable fringe benefits and certain other amounts. Once income exceeds the minimum threshold, you repay a percentage of your total income, not just the portion above the threshold.
The minimum repayment threshold changes each year — check ato.gov.au for the current figure. At the minimum threshold, the repayment rate is 1% of total income. The rate rises progressively with income, reaching 10% for the highest income band.
Indexation
On 1 June each year, the ATO applies CPI indexation to outstanding HECS-HELP balances. The indexation rate equals the percentage change in the Consumer Price Index over the 12 months to March of that year.
For most of the 2010s, indexation was between 1% and 3%. The 2023 indexation rate was 7.1%, reflecting higher inflation in 2022-23. A $50,000 debt indexed at 7.1% would increase by $3,550 in one year. This made early repayment discussions more common than they had been in previous low-inflation years.
Indexation is applied to the balance before any compulsory repayments made during the financial year. Voluntary repayments reduce the balance the indexation is calculated on if made before 1 June.
Should you pay it off early?
This is one of the most debated personal finance questions for Australians with HECS debt. The core comparison is: does paying off HECS give a better financial return than using that money for something else?
If the indexation rate is lower than the return you could earn by investing instead, keeping the HECS debt and investing the surplus is mathematically preferable. In a low-inflation environment (2% indexation vs 7% investment return), this argument is straightforward.
When indexation spikes — as in 2023 — the calculation shifts. A 7% indexation rate is close to or higher than safe investment return assumptions. The certainty of eliminating the debt also has value that pure return comparisons do not capture.
There is no single right answer. It depends on indexation forecasts, your investment returns, your cash position, and personal preference for carrying debt.
Voluntary repayments
You can make voluntary repayments to the ATO at any time through MyGov or by direct payment. Unlike the compulsory repayments, these do not affect your take-home pay throughout the year — they reduce your outstanding balance directly.
Note that voluntary repayment bonuses (which used to offer a 5% or 10% discount) were removed in 2017. There is no longer a financial incentive from the government for early voluntary repayment beyond the interest-rate comparison above.
Common misconceptions
"HECS is interest-free so I should ignore it"
Ignoring indexation as a cost is a mistake. CPI indexation increases the real value of the debt each year. In low-inflation years the cost is minor, but the debt is not static.
"I should always pay it off as fast as possible"
This depends on the math in any given year. In low-inflation years, investing produces better expected returns than paying off HECS. Blanket urgency about repayment is not always justified.
"My debt will be forgiven if I don't pay it off"
HECS-HELP debt is only cancelled upon death or permanent incapacity. There is no statute of limitations or forgiveness after a certain number of years. The debt stays until it is repaid.
Frequently asked questions
Does HECS debt affect my ability to borrow for a home?
Yes, indirectly. Lenders assess your repayment commitments as part of borrowing capacity calculations. Compulsory HECS repayments reduce your disposable income and therefore the loan amount a lender may approve. Paying down HECS before applying for a mortgage can increase borrowing capacity in some cases.
What happens to HECS debt if I move overseas?
Since 2017, Australians living overseas with HECS-HELP debt must make repayments if their worldwide income exceeds the repayment threshold. You report income through the ATO each year and repayments are assessed. The debt does not pause simply because you are not living in Australia.
Does HECS debt show on my credit file?
No. HECS-HELP debt is not a credit liability and does not appear on credit reports. However, it is visible to the ATO and will appear on lenders' income assessments if you provide recent tax returns or ATO notices.
When is the indexation applied each year?
Indexation is applied on 1 June each year to balances outstanding at that date. Voluntary repayments made before 1 June reduce the balance that indexation is calculated on. Timing a voluntary repayment before that date can reduce the indexation cost for that year.
