HECS-HELP Debt in Australia: Repayment Thresholds, Indexation and Whether to Pay It Off Early (2026)
Around three million Australians carry a HECS-HELP debt. Most know repayments come out of their pay — but few understand exactly how the system works, what indexation really costs them, or how their student debt quietly reduces their borrowing power when they apply for a home loan. This guide breaks down the mechanics of HECS-HELP in 2025–26 with real dollar examples.
This guide is general information only and does not constitute financial advice. Consider your own circumstances and seek professional advice before making financial decisions.
How HECS-HELP Actually Works
HECS-HELP (Higher Education Contribution Scheme — Higher Education Loan Program) is a government loan that covers part or all of your university tuition. The key features that make it different from every other debt:
- No interest charged. HECS-HELP does not accrue interest like a credit card or personal loan.
- Indexed to inflation. On 1 June each year, the ATO applies an indexation rate to your outstanding balance. Since 2023–24, this rate is capped at the lower of CPI or the Wage Price Index (WPI).
- Compulsory repayments tied to income. Once your repayment income exceeds the minimum threshold, your employer withholds a percentage through PAYG — similar to tax.
- No set term. There is no deadline to repay. If your income stays below the threshold, you never have to repay. The debt is cancelled if you die or become permanently incapacitated.
Repayment Thresholds and Rates for 2025–26
Compulsory repayments only kick in when your repayment income (taxable income plus any net investment losses, reportable fringe benefits, and reportable super contributions) exceeds the minimum threshold. For 2025–26:
| Repayment Income | Repayment Rate |
|---|---|
| Below $54,435 | Nil |
| $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 – $89,154 | 4.5% |
| $89,155 – $94,503 | 5.0% |
| $94,504 – $100,174 | 5.5% |
| $100,175 – $106,185 | 6.0% |
| $106,186 – $112,556 | 6.5% |
| $112,557 – $119,309 | 7.0% |
| $119,310 – $126,467 | 7.5% |
| $126,468 – $134,056 | 8.0% |
| $134,057 – $142,100 | 8.5% |
| $142,101 – $150,626 | 9.0% |
| $150,627 – $159,663 | 9.5% |
| $159,664 and above | 10.0% |
The rate applies to your entire repayment income, not just the amount above the threshold. This creates a cliff effect — earning $1 above a threshold can increase your compulsory repayment by hundreds of dollars.
Worked Example: The Threshold Cliff
Sarah earns $54,434 — repayment income just below the first threshold.
Compulsory HECS repayment: $0
Sarah gets a $100 pay rise, pushing her repayment income to $54,535.
New compulsory repayment: $54,535 × 1.0% = $545 per year
The $100 raise costs her $545 in HECS repayments — a net loss of $445. In practice, salary sacrifice into super can keep repayment income below the threshold, though this only makes sense if you were already planning to contribute more to super.
How Indexation Works (and What It Costs You)
Each 1 June, the ATO increases your outstanding HECS-HELP balance by an indexation factor. This isn't "interest" — it's a price adjustment to maintain the real value of the debt. But it has the same practical effect: your balance grows.
Since 2023–24, indexation has been capped at the lower of CPI or the Wage Price Index (WPI). This was introduced after the 2022–23 spike when CPI hit 7.1%, causing widespread outrage as balances jumped overnight. The cap means indexation is now typically 3–4% rather than tracking headline inflation during price spikes.
Worked Example: The Cost of Indexation Over Time
James graduates with a $45,000 HECS-HELP debt. Assume indexation averages 3.5% per year and James makes no voluntary repayments.
| Year | Opening Balance | Indexation (3.5%) | Compulsory Repayment | Closing Balance |
|---|---|---|---|---|
| 1 | $45,000 | $1,575 | $0 (below threshold) | $46,575 |
| 2 | $46,575 | $1,630 | $0 (below threshold) | $48,205 |
| 3 | $48,205 | $1,687 | $680 (income now $68,000) | $49,212 |
| 4 | $49,212 | $1,722 | $2,240 (income now $80,000) | $48,694 |
| 5 | $48,694 | $1,704 | $3,825 (income now $85,000) | $46,573 |
After five years of working, James has paid $6,745 in compulsory repayments — but $8,318 has been added through indexation. His balance is higher than when he graduated despite making repayments. It takes until around year 4 for compulsory repayments to outpace indexation. This is the experience for most graduates in the early years of their career.
Timing Trick: Voluntary Payments Before 1 June
Indexation is applied to the balance as at 1 June. Any voluntary repayment that reaches the ATO before 1 June reduces the balance that indexation applies to. If you're going to make a voluntary payment anyway, doing it in May rather than July saves you the indexation on that amount.
Example: A $5,000 voluntary payment made on 25 May at 3.5% indexation saves $175 compared to making the same payment on 2 June. Small, but free money if you were planning to pay anyway.
HECS-HELP and Your Home Loan Borrowing Power
This is where HECS-HELP stops feeling like "soft" debt and starts having real consequences. When you apply for a home loan, lenders include your compulsory HECS repayment as a non-discretionary expense — it reduces your borrowing capacity just like a car loan or credit card repayment.
How Banks Calculate the Impact
Banks don't use your current HECS repayment. They calculate your repayment at the assessment rate — your income plus the bank's 3% serviceability buffer. This means the HECS repayment they use is higher than what you currently pay.
| Your Income | HECS Repayment Rate | Annual HECS Repayment | Approx. Reduction in Borrowing Power |
|---|---|---|---|
| $70,000 | 2.5% | $1,750 | ~$21,000 |
| $85,000 | 4.5% | $3,825 | ~$46,000 |
| $100,000 | 5.5% | $5,500 | ~$66,000 |
| $120,000 | 7.0% | $8,400 | ~$101,000 |
| $150,000 | 9.0% | $13,500 | ~$162,000 |
The borrowing power reduction is roughly 12× the annual HECS repayment — because lenders convert your annual commitment to a monthly figure and factor it into their serviceability calculation at the stressed rate.
Key Point
If you earn $100,000 and carry a HECS debt, a bank treats you roughly the same as someone earning $100,000 who has a $460/month car loan but no HECS. The HECS repayment is invisible to you (it comes out with your tax), but the bank sees it as a real expense that reduces your capacity to service a mortgage.
Should You Pay Off HECS-HELP Early?
This is the most common question — and the answer is almost always no, with a few exceptions.
The Case Against Paying Early
- Indexation is not interest. At 3–4%, HECS indexation is your cheapest "debt." A home loan at 6.5% costs almost double. Credit cards at 20%+ cost five times more. Every dollar used to pay HECS early is a dollar not attacking higher-cost debt.
- No penalty for slow repayment. Unlike a mortgage, there's no compounding interest that makes early repayment exponentially more valuable.
- Opportunity cost. $20,000 invested in a diversified ETF portfolio averaging 7–8% returns significantly outperforms "saving" 3.5% in avoided indexation.
- Liquidity matters. Once you pay the ATO, you can't get the money back. An emergency fund or investment portfolio is accessible; a HECS payment is gone forever.
The Case For Paying Early
- You're about to apply for a home loan and you're borderline. If paying off $15,000 in HECS would increase your borrowing power by $30,000–$50,000 and that's the difference between qualifying for the property you want or not — the maths changes. But only if you have the cash without depleting your deposit or emergency fund.
- You have no other higher-priority uses for the money. No high-interest debt, fully funded emergency fund, maxed out super contributions, and a comfortable investment portfolio. In this case, eliminating HECS removes an ongoing drag on your take-home pay.
- Psychological benefit. Some people find carrying any debt stressful. If clearing your HECS lets you sleep better and it won't compromise other financial goals, the emotional benefit has real value.
The Decision Framework
| Priority | Action | Why It Comes Before HECS |
|---|---|---|
| 1 | Pay off credit cards and personal loans | 18–22% interest vs 3–4% indexation — not even close |
| 2 | Build an emergency fund (3–6 months) | Liquidity protects you from going into high-interest debt |
| 3 | Salary sacrifice or contribute to super | Tax savings of 19–32% beat avoiding 3–4% indexation |
| 4 | Save for a home deposit | Building equity in property beats eliminating a low-cost debt |
| 5 | Extra mortgage repayments | Mortgage rate of 6–7% is almost double the indexation rate |
| 6 | Invest in ETFs or shares | Long-term market returns of 7–10% outperform 3–4% indexation |
| 7 | Voluntary HECS repayments | Only after everything above is covered |
HECS-HELP Strategies for Different Situations
Strategy 1: The Early-Career Graduate
Situation: Earning $55,000–$70,000 with a $30,000–$50,000 HECS debt. No other major financial commitments.
Best move: Ignore the HECS debt entirely. Focus on building an emergency fund and starting regular ETF investments (even $100/month makes a difference over a decade). Your compulsory repayments are small at this income level and indexation is a minor cost compared to the benefit of building wealth early through compound returns.
Strategy 2: The Pre-Home-Buyer
Situation: Earning $90,000–$120,000 with $25,000 remaining HECS debt. Planning to buy in the next 12–18 months.
Best move: Run the numbers with a mortgage broker. Ask them to calculate your borrowing power with and without the HECS debt. If the difference means you qualify for the property you want, consider paying down some or all of the debt — but only from savings above your deposit and emergency fund. If you qualify comfortably either way, keep the HECS and preserve your cash for stamp duty, moving costs, and the first months of homeownership.
Strategy 3: The High Earner
Situation: Earning $150,000+ with a $20,000 HECS debt. Compulsory repayments are $13,500+/year — the debt will be cleared in under two years anyway.
Best move: Let compulsory repayments do the work. At this income, the debt will be paid off quickly through PAYG withholding. A $20,000 voluntary payment just to save $700 in indexation isn't worth the loss of liquidity. The one exception: making a payment in late May to reduce the June indexation hit if the debt would otherwise carry over another year.
Common HECS-HELP Mistakes
1. Not Claiming the HECS Withholding on Your Tax Return
Your employer withholds HECS repayments throughout the year based on your pay cycle. When you lodge your tax return, the ATO calculates your actual repayment based on your total repayment income. If you've been over-withheld (because your employer calculated each pay as if you earned that rate all year, when you started mid-year), you'll get the excess back as a tax refund. Always check your income statement against the ATO's assessment.
2. Forgetting HECS When Doing a Side Hustle
If you have a second job, freelance income, or investment income, this all counts towards your repayment income. Many people get an unexpected HECS bill at tax time because their combined income pushed them into a higher repayment band. If you earn income outside your main PAYG job, budget for the additional HECS repayment.
3. Salary Sacrificing Without Considering HECS
Salary sacrificing into super reduces your taxable income but does not reduce your HECS repayment income. Reportable super contributions are added back when calculating repayment income. This catches people who salary sacrifice to lower their tax, only to find their HECS repayment is the same or higher than expected.
4. Treating HECS Like Urgent Debt
Parents and well-meaning relatives often push graduates to "pay off your HECS as soon as possible." This advice made more sense before 2005, when voluntary repayments received a bonus discount (10% or 15%). Those bonuses no longer exist. Today, a voluntary HECS payment returns exactly 3–4% (the avoided indexation) — making it one of the lowest-return uses of your cash.
HECS-HELP and Going Overseas
If you move overseas and your worldwide income exceeds the repayment threshold, you are still required to make HECS repayments. Since 2017, Australian residents working overseas must lodge an overseas HELP repayment return and make compulsory repayments based on their worldwide income.
The thresholds and rates are the same as for domestic earners. Failure to lodge attracts penalties. The ATO can also recover debts from your Australian assets or tax refunds.
Quick Reference: HECS-HELP in 2025–26
| Item | Detail |
|---|---|
| First repayment threshold | $54,435 |
| Maximum repayment rate | 10% of repayment income |
| Indexation cap | Lower of CPI or WPI |
| Indexation date | 1 June each year |
| Voluntary repayment bonus | None (abolished 2017) |
| Overseas repayment obligation | Yes — worldwide income assessed |
| Debt discharged on death | Yes |
| Tax deductible? | No |
The Bottom Line
HECS-HELP is the cheapest debt most Australians will ever carry. The indexed growth rate of 3–4% is less than half a typical mortgage rate and a fraction of credit card interest. Unless you're on the borderline of qualifying for a home loan, voluntary repayments almost never make financial sense.
The best strategy for most people: let compulsory repayments do their job, focus your cash on higher-priority goals (emergency fund, super, investing, home deposit), and if you do make a voluntary payment, time it for late May to minimise the 1 June indexation hit.
Your HECS debt is not holding you back nearly as much as you think. The real cost is the borrowing power reduction — and even that can be managed with the right strategy and a good mortgage broker.
