What is HECS-HELP debt, and how do you repay it? A beginner's guide

How are HECS-HELP repayments calculated?

HECS-HELP debt is the loan most Australian university students use to pay their student contribution, part of the Higher Education Loan Program (HELP). You do not repay it in fixed instalments. Instead, the Australian Taxation Office (ATO) collects compulsory repayments through the tax system once your income passes a threshold, and only on the income above that threshold.

The quick answer for 2026-27: the ATO's table shows no compulsory repayment on repayment income up to $69,528; 15 cents for each dollar over $69,528 up to $129,717; $9,028 plus 17 cents for each dollar over $129,717 up to $186,050; and 10% of total repayment income from $186,051. For 2025-26 the threshold was $67,000.

Compulsory repayments are now worked out on a marginal basis: only on income above the minimum repayment threshold, not on your whole income. The ATO says thresholds and rates are indexed each year in line with average weekly earnings.

ATO worked example (2025-26): Grace has a repayment income of $80,000. Under the old system her compulsory repayment would have been $2,800, or 3.5% of her income. Now she pays 15% of income above $67,000, which is 15% of $13,000, or $1,950. Paid fortnightly, she gets around $32 extra each pay.

Illustration using the 2026-27 table: on repayment income of $90,000, the amount above $69,528 is $20,472, and 15% of that is $3,070.80 for the year.

More illustrations from the 2026-27 table: at $150,000 of repayment income, the amount over $129,717 is $20,283; 17% of that is $3,448.11, plus the fixed $9,028, giving $12,476.11. At $200,000, which is above $186,051, the repayment is 10% of the whole $200,000, or $20,000. Check the 2025-26 figures the same way: at exactly $125,000, 15% of the $58,000 above $67,000 is $8,700, which is why the next band starts at $8,700.

Because the bands move up each year with average weekly earnings, a pay rise that only keeps pace with wages may not raise your repayment as much as you expect. Always use the table for the income year you are lodging for.

High earners: the ATO says there is no change for people earning $179,286 or more under the 2025-26 table, where repayments remain 10% of total repayment income. In 2026-27 that top rate starts at $186,051.

Readers evaluating HECS-HELP debt should separate marketing claims from the actual rule text that governs their account or product. When two summaries disagree, the governing document or statute wins. If a rule depends on your age, filing status, or income band, re-check it when any of those facts change. Life events quietly move people across thresholds they last reviewed years earlier.

Educational explainers like this one cannot replace personalized advice for complex situations such as divorce orders, inherited accounts, or cross-border tax residency. Escalate those cases to a qualified professional. When in doubt about a number that changes every year, describe your plan qualitatively first, then look up the current official figure for the tax year you care about before you act.

What counts as repayment income?

Repayment income is not just your salary. The ATO adds together taxable income (excluding any assessable First Home Super Saver released amounts), reportable fringe benefits, total net investment loss including net rental losses, reportable super contributions, and exempt foreign employment income.

That means negatively geared property losses and salary sacrifice into super do not reduce your repayment income. See and

The same thresholds apply to other study and training loans, including VET Student Loans, the Student Financial Supplement Scheme, ABSTUDY Student Start-up Loans and Australian Apprenticeship Support Loans.

If you pay tax by instalments rather than PAYG withholding, the ATO says the marginal changes were not applied to instalments until 1 July 2026, with any extra paid for 2025-26 returned in your 2026 assessment if you have no other Commonwealth debts.

A useful habit is to write down your goal, time horizon, and cash buffer before you change any election related to HECS-HELP debt. Decisions made during a stressful week are the ones people reverse later at a cost.

How does indexation work?

HELP debts are indexed, with the rate applied on 1 June each year. Following the May 2024 Budget, the Department of Education says indexation is based on the lower of the Consumer Price Index (CPI) or the Wage Price Index (WPI), backdated to 1 June 2023, so indexation will never be higher than the change in wages.

That cap cut the 1 June 2023 rate from 7.1% to 3.2% and the 1 June 2024 rate from 4.7% to 4%, with credits applied automatically.

The 20% reduction was backdated to 1 June 2025, and the ATO says the 2025 indexation was then adjusted to the lower balance. Where accounts went into credit, refunds were processed if there were no other tax or Commonwealth debts.

Keep digital and paper copies of confirmations after every change. Screenshots of election pages, email receipts, and year-end statements make tax season and job changes far less chaotic. Compare fees the same way you would compare two similar listings before you buy: look at what you pay each year, what you get, and whether a simpler option meets the same need.

How should you manage your HELP debt?

Check your balance: view your loan account in the ATO app or ATO online services through myGov.

Voluntary repayments: the ATO says you can make voluntary repayments at any time to reduce your debt. Whether that beats other uses of your money, such as an emergency fund or a home deposit, depends on your situation.

Plan for big purchases: compulsory repayments reduce take-home pay, which can matter when budgeting for a mortgage; run numbers with our

Keep records: your notice of assessment shows the compulsory repayment raised each year, and your ATO online account shows the balance after indexation and any reductions. Comparing the two each year helps you spot errors early and plan voluntary repayments if you choose to make them.

Update your details, especially bank accounts, so any refunds reach you, and lodge tax returns on time.

If a rule depends on your age, filing status, or income band, re-check it when any of those facts change. Life events quietly move people across thresholds they last reviewed years earlier. Automation helps. Calendar reminders for annual reviews, automatic transfers, and beneficiary checkups reduce the chance that a good plan dies from neglect.
