What Is HECS-HELP? The Quick Version
HECS-HELP is the Australian Government's income-contingent student loan program. If you studied at an eligible higher education provider — almost every university in Australia — the government lent you the money for your tuition fees. You repay it through the tax system once your income crosses a threshold. No monthly bills, no credit checks, no compound interest.
More than 3 million Australians carry a HECS-HELP debt, with a combined balance now exceeding $78 billion. The average debt for a bachelor's degree graduate sits at approximately $26,000 to $28,000, according to government data and analysis from registered financial professionals.
What makes it different from a personal loan is the repayment mechanic: you only pay when you earn enough, and only on the income above the threshold — not on every dollar you earn. Two reforms in 2025 changed that mechanic fundamentally, and a third indexation event in June 2026 moved the numbers again. If you want to understand what comes out of your pay packet, our Australia salary after-tax calculator shows HECS repayment alongside your full income breakdown.
The Biggest HECS Changes in a Generation
If you haven't checked your HELP debt since early 2025, you're in for a surprise — a largely pleasant one. Between August 2025 and July 2026, three separate changes landed on top of each other: a one-off debt cut, a brand-new way of calculating repayments, and a threshold that keeps rising with indexation. Here's each one, and — more importantly — which numbers actually apply to you right now.
The 20% Debt Cut
The Universities Accord (Cutting Student Debt by 20 Per Cent) Bill 2025 became law on 2 August 2025. The Australian Taxation Office applied a one-off 20% reduction to all eligible HECS-HELP balances as at 1 June 2025 — automatically, before that year's indexation was added.
You didn't need to apply. If you had a $30,000 debt on 1 June 2025, it became $24,000. For the average debtor carrying approximately $27,600, the cut wiped around $5,520 from the balance before a single repayment was required. High-balance graduates — those with medical, dental, or law degrees carrying $80,000 to $104,000 in debt — received the largest dollar reductions. There is no second 20% reduction scheduled; only the annual indexation event continues from here.
The 20% reduction was applied by the ATO and notified via SMS, email, or myGov Inbox. Check your ATO online account via myGov to see your current balance if you haven't already. Source: ATO — Study and training loans: what's new.
The New Marginal Repayment System
From 2025–26, the ATO switched from a flat-rate system — where a single percentage applied to your entire income — to a marginal repayment system, where you only pay on income above the threshold. This replaced 19 flat-rate income tiers with four marginal bands, the same logic as income tax brackets.
Which Numbers Apply to You Right Now: 2025–26 or 2026–27?
Here's where most calculators and explainer pages create confusion: two different sets of thresholds are both technically "current" at the same time, depending on what you're doing with them.
If you're lodging your tax return for the 2025–26 financial year (1 July 2025 to 30 June 2026) — which most people do between July and October 2026 — your compulsory repayment is worked out on the 2025–26 bands below.
But if you're checking what's actually being withheld from your pay right now, you're earning in the 2026–27 financial year, which started 1 July 2026. A new, higher set of thresholds applies instead — the dollar cut-offs moved up with the 2.8% indexation applied on 1 June 2026, but the rates themselves (15%, 17%, 10%) are unchanged.

How to Check Your HECS-HELP Debt Balance
Your payslip does not show your HECS-HELP balance. It only shows what your employer withheld this pay cycle, as an estimate toward your annual repayment. Your employer has no visibility into what you actually owe — it isn't their account to see. That single point of confusion accounts for a large share of the "how do I check my HECS debt" searches people run.
Compulsory repayments withheld from your pay through the year don't reduce your loan account balance until your tax return is assessed — sometimes months after the money left your pay. Don't be alarmed if your myGov balance doesn't move for most of the year; it catches up at tax time, all at once.
HECS Indexation in 2026: The Silent Balance Grower
Indexation is the mechanism that adjusts your HELP debt upward each year to preserve its real value. It applies on 1 June to all debts at least 11 months old — and it applies whether you are earning above the threshold or not. Below-threshold earners still see their balance grow.
Since 1 June 2023, the ATO caps indexation at the lower of the Consumer Price Index (CPI) or the Wage Price Index (WPI). Before this reform, debts grew at raw CPI — which hit 7.1% in June 2023, generating enormous anger and media coverage. The WPI cap brought that down to 3.2% on a backdated basis, and the rate has fallen every year since.
Indexation applies to your balance on 1 June. Any voluntary repayment made before 1 June and actually cleared by the ATO reduces the balance that indexation is calculated on — meaning you save on the inflation-linked growth, not just the debt itself. The next indexation event lands 1 June 2027, based on CPI and WPI data to March 2027; the ATO typically confirms the exact figure in the third week of May.
Should You Make Voluntary Repayments?
Since July 2022, the ATO no longer offers a 5% bonus for voluntary repayments. The incentive that once made paying ahead financially attractive is gone. This doesn't mean voluntary repayments are useless — it means the calculus changed.
The case for voluntary repayments now rests on one question: do you have a better use for the money? HECS-HELP remains one of the cheapest debts most Australians will ever carry. There is no interest — only indexation. Compare that to a mortgage at 6%+, credit card debt at 20%+, or a personal loan. Those should be cleared first.
If you have no high-interest debt, a healthy emergency fund, and are not planning to buy property in the near term — voluntary repayments before 1 June each year reduce both the balance and the amount indexed. For large debts or those approaching retirement with super considerations, a financial adviser can help model the trade-offs. For the full salary picture, our ATO tax calculator shows how repayments interact with your income tax.
The marginal repayment system also eliminates the old "threshold cliff" problem. Previously, crossing a threshold by $1 could trigger a large jump in repayments. Under the new system, there is no cliff — so salary sacrifice to super no longer makes sense purely as a HECS avoidance strategy, though it remains valuable for tax and retirement purposes. See our Australia superannuation calculator to model salary sacrifice and super contributions side by side.
One arrangement worth flagging on its own: salary packaging, common in health, not-for-profit and public-sector roles. Packaging a novated lease, a meal and entertainment card, or similar benefits reduces your income tax — but the packaged value is added back to your repayment income as a reportable fringe benefit. That means salary packaging can quietly increase your compulsory HECS repayment even as it lowers your take-home tax, which is the opposite of what most people assume when they set the arrangement up. If you package benefits and also carry a HECS debt, check the reportable fringe benefit amount on your income statement each year rather than assuming the two are unrelated.
How to Use This HECS-HELP Repayment Calculator
The calculator gives you a full picture in a single view — not just the HECS repayment, but income tax, Medicare levy, take-home pay, and a debt payoff projection based on your current balance and indexation assumption. Here's how to get the most from it:
Your repayment income for ATO purposes may include more than your base salary — it also includes reportable fringe benefits, net rental losses, and reportable employer super contributions (see the FAQ below for how deductions and negative gearing interact with this).
