What Is HELP Debt?
The Higher Education Loan Program (HELP) — commonly still called HECS — is the Australian government's income-contingent student loan scheme. When you study at an eligible institution, you can defer your tuition fees as a HELP debt rather than paying upfront. The debt sits with the ATO and is only repaid once your income reaches a certain threshold.
It sounds straightforward. But for many graduates, the details of how and when repayments are triggered — and how indexation chips away at them — can be a surprise. Try our Study Loan Repayment Calculator → to see how long your debt will take to clear.
How HELP Repayments Are Triggered
HELP repayments are not optional. Once your repayment income exceeds the minimum threshold, the ATO automatically calculates a repayment as part of your annual tax assessment. For 2024–25, the repayment thresholds and rates are:
- Below $54,435: 0% — no repayment required
- $54,435 – $62,850: 1.0%
- $62,851 – $66,620: 2.0%
- $66,621 – $70,618: 2.5%
- $70,619 – $74,855: 3.0%
- $74,856 – $79,346: 3.5%
- $79,347 – $84,107: 4.0%
- $84,108 – $88,756: 4.5%
- $88,757 – $93,996: 5.0%
- $93,997 – $99,996: 5.5%
- $100,000 – $107,896: 6.0%
- Above $141,848: 10.0%
Note: these rates apply to your entire repayment income at that rate — they're not marginal like income tax brackets. So earning $1 more above a threshold triggers the higher rate on your whole income.
What Is "Repayment Income"?
Your HELP repayment income is broader than your taxable income. It includes your taxable income plus any reportable fringe benefits, reportable employer super contributions, and total net investment losses. This can catch some people out — especially those who salary sacrifice into super, as the sacrificed amount may be added back in for HELP repayment purposes.
HELP Repayment Through PAYG vs Tax Return
If you tell your employer you have a HELP debt (via your TFN declaration), they will withhold extra tax each pay cycle to cover your estimated repayment. This avoids a large tax bill at the end of the year.
If you don't notify your employer, no additional withholding occurs, and you'll receive a debt from the ATO when you lodge your tax return. This doesn't incur interest, but it can be an unpleasant surprise. See how HELP withholding affects your take-home pay →
Indexation: The Hidden Growth Factor
HELP debts are indexed annually on 1 June, linked to either the Consumer Price Index (CPI) or the Wage Price Index (WPI) — whichever is lower. For many years indexation was negligible, but in 2023 it hit 7.1%, adding thousands to many graduates' balances overnight and triggering significant public debate.
The government subsequently legislated a cap so that indexation cannot exceed 3% going forward. Still, indexation means carrying a HELP debt longer is more expensive than many people assume.
Should You Pay Your HELP Debt Down Voluntarily?
Voluntary repayments (made directly to the ATO, not through your employer) reduce your HELP balance immediately. There is no bonus discount for early repayment anymore — that scheme was abolished. The main benefit of voluntary repayment is reducing future indexation. Whether it's the best use of your money depends on your other financial commitments and interest rates on any other debt you hold.
Tools to Help You Plan
Keeping track of your HELP balance, annual repayments, and projected payoff date is much easier with the right tools. Our Study Loan Repayment Calculator → lets you enter your current balance and income to project exactly when you'll be debt-free.

Key Takeaways
- HELP repayments are automatic once your income crosses the threshold — you cannot defer them further
- Your repayment rate applies to your total repayment income, not just the amount over the threshold
- Indexation can grow your balance — paying it down faster may make sense if you have spare cash
- Always declare your HELP debt to your employer to avoid a large end-of-year tax bill
