HECS-HELP Explained: A Plain-English Guide
HECS-HELP is the loan name most Australians know — and most do not understand in detail. This guide walks through what HECS-HELP is, what it is not, who can access it, how the debt grows during your degree, and the income point at which the Australian Taxation Office begins withholding repayments through the tax system.
What HECS-HELP actually is
HECS-HELP is one of seven loan schemes in the Australian Government's Higher Education Loan Program (HELP). It specifically covers the student contribution amount for a Commonwealth Supported Place (CSP) — a domestic-undergraduate (and some postgraduate) study place at an approved provider where the Commonwealth subsidises the bulk of the tuition. You only see your student contribution; the Government pays the rest directly to your university.
When you defer this contribution rather than paying it up front, you take out a HECS-HELP loan. The loan is recorded against your tax file number (TFN), accumulates interest-free while you study (it is indexed annually — see below), and is repaid automatically through the tax system once your income crosses a published threshold.
Who is eligible
To access HECS-HELP you must be either:
- An Australian citizen, or
- A New Zealand Special Category Visa (SCV) holder who meets long-term-residence rules, or
- A permanent humanitarian visa holder.
Permanent residents and international students cannot use HECS-HELP for their CSP contribution. Permanent residents in some courses can use FEE-HELP for full-fee places (see our FEE-HELP vs HECS-HELP guide), and international students typically pay tuition up front.
How much you borrow per year
Your annual student contribution amount depends on the cluster the Commonwealth places each unit into under the 2021 Job-ready Graduates reform. For 2026 the indicative annual bands are:
- Cluster 1 ($4,627): teaching, nursing, English, agriculture, science, maths, and some clinical psychology and statistics.
- Cluster 2 ($8,948): allied health, architecture, the built environment, and veterinary science.
- Cluster 3 ($12,720): engineering, science (most), IT and computing, surveying, and environmental studies.
- Cluster 4 ($16,992): humanities, business, law, communications and the social sciences.
The cluster applies to the unit, not the degree as a whole. A combined Bachelor of Engineering / Bachelor of Arts therefore accumulates a mix of cluster 3 and cluster 4 contributions. Your unit guide tells you which cluster each unit sits in, and your university's HECS statement of account at the end of each term shows the contribution added to your loan.
Annual indexation, not interest
HECS-HELP does not charge interest. Instead, the outstanding balance is indexed once a year on 1 June. From 1 June 2024 onwards, under the Higher Education Support Amendment Act 2024, indexation is calculated as the lower of:
- The Consumer Price Index growth over the year to 31 March, or
- The Wage Price Index growth over the year to 31 March.
The dual-cap rule replaced the CPI-only rule retroactively, with the ATO issuing credit adjustments for affected borrowers during 2024 and 2025. The practical effect is to cap the indexation rate during high-inflation years where wages have not kept pace — a structural change for borrowers carrying balances through the 2022–2024 CPI spike. For more on the mechanics see our indexation explainer.
When you start repaying
Compulsory repayment begins automatically through the tax system once your repayment income exceeds the lowest threshold published by the Australian Taxation Office. For the 2026-27 financial year the minimum threshold sits at $54,435 with a 1% repayment rate, scaling up across nineteen bands to a top rate of 10% on income above $159,663.
Critically, repayment income is not your taxable income. It is taxable income plus any reportable fringe benefits, total net investment loss, reportable employer superannuation contributions, and exempt foreign employment income. The full 19-band schedule is available on our thresholds page, and the HECS-HELP calculator applies it to any income figure you supply.
A common misconception: the threshold rate is not marginal
What happens during a low-income year
Below the minimum threshold no compulsory repayment is owed, but the balance is still indexed each 1 June. A graduate in a low-income year can therefore see their balance grow slightly even with no repayment activity. Voluntary repayments remain available at any time and are credited the same day they are paid — see our voluntary repayments guide for whether they are worth making.
What happens when you move overseas
Australian citizens with a HECS-HELP debt who become non-residents for tax purposes must still report their worldwide income to the ATO each year and may owe foreign-sourced repayment at the published rates if their worldwide income exceeds the minimum threshold. Failing to lodge a non-resident return is the most common compliance pitfall for HELP debtors abroad.
When the balance is forgiven
HECS-HELP debt is treated differently from other types of debt: it does not transfer to your estate on death, and it is not enforceable through standard debt-collection processes. An outstanding balance is written off on the borrower's death, which is one reason the Government models HELP cohorts using a "doubtful debt" allowance rather than booking every balance as a recoverable asset.
