HECS-HELP Debt in 2026: The 20% Cut, New Marginal Repayment System, and What It Means for Your Finances

If you have a HECS-HELP debt in Australia, 2026 has brought two of the most significant changes to student loan repayments in the scheme’s 37-year history. The government has wiped 20% off every outstanding HELP balance, and the way compulsory repayments are calculated has been completely overhauled.

These changes affect approximately 3 million Australians who carry HELP debt. Whether you are a recent graduate, a mid-career professional still chipping away at your balance, or a parent helping your children understand the system, this guide explains exactly what has changed, how it affects your finances, and what you should do about it.

The 20% Debt Reduction: What Actually Happened

In early 2026, the Australian Government applied a flat 20% reduction to every outstanding HELP debt in the country. This was one of the key recommendations from the Australian Universities Accord review, led by Professor Mary O’Kane, which found that student debt had become an unreasonable burden, particularly for lower-income graduates and those in public service roles.

How the Reduction Was Calculated

The 20% cut was applied to your HELP balance as at 1 June 2025, before the annual indexation adjustment. The ATO processed it automatically. You did not need to apply, fill in forms, or contact anyone.

Here is what it looked like in practice:

For context, the average HELP debt for a bachelor’s degree graduate in Australia is approximately $26,000. A 20% reduction on that is $5,200 wiped from the balance, a meaningful difference that could reduce repayment timelines by one to three years depending on income.

Who Benefited Most

The reduction applied equally to all debtors as a percentage, but the practical impact varies:

• Lower-income earners benefit most in relative terms because the reduced balance means they cross the repayment threshold later and for shorter periods, meaning lower lifetime repayments.
• High-balance debtors (those with postgraduate degrees, particularly medicine, dentistry, and law graduates who can carry $80,000 to $104,000 in debt) received the largest dollar reductions.
• People close to paying off their debt may have had their balance eliminated entirely or reduced to a level that will be cleared within one to two tax years.

The Cost to Government

The 20% reduction cost the federal budget approximately $16 billion in foregone revenue. The government funded it partly through the Division 296 superannuation tax on balances above $3 million (which passed into law on 10 March 2026) and partly through general revenue.

The New Marginal Repayment System

The second major change is how compulsory repayments are calculated. From 1 July 2025 (affecting 2025-26 tax returns lodged from July 2026 onwards), HELP repayments use a marginal system rather than a percentage of total income.

How the Old System Worked

Under the previous system, once your repayment income exceeded the minimum threshold ($54,435 in 2024-25), you paid a percentage of your entire repayment income, not just the amount above the threshold.

This created a harsh cliff effect. If you earned $54,434, you paid nothing. If you earned $54,436, you suddenly owed 1% of your entire income ($544). The rates scaled up to 10% of total income for high earners.

This system was widely criticised for being punitive, particularly for people hovering around the threshold who could face effective marginal tax rates above 50% when HELP repayments were combined with income tax and the Medicare levy.

How the New Marginal System Works

The new system works like income tax brackets. You only pay on income above the threshold, not on your entire income. Here are the 2025-26 rates:

Practical Examples

Let’s compare the old and new systems for common income levels:

Example 1: Emma earns $75,000

• Old system: 2% of $75,000 = $1,500
• New system: ($75,000 - $67,000) x 15% = $1,200
• Saving: $300 per year

Example 2: James earns $90,000

• Old system: 3.5% of $90,000 = $3,150
• New system: ($90,000 - $67,000) x 15% = $3,450
• James actually pays slightly more under the new system at this income level

Example 3: Sarah earns $110,000

• Old system: 5% of $110,000 = $5,500
• New system: ($110,000 - $67,000) x 15% = $6,450
• Sarah pays more under the new system

Example 4: David earns $68,000

• Old system: 1% of $68,000 = $680
• New system: ($68,000 - $67,000) x 15% = $150
• Saving: $530 per year

The key takeaway: the new marginal system benefits lower-income earners significantly (particularly those just above the threshold) but can result in slightly higher repayments for middle-income earners between approximately $85,000 and $150,000. Higher earners above $179,286 still pay the same 10% of total income as before.

The Cliff Effect Is Gone

The most important improvement is the elimination of the cliff effect. Under the old system, someone earning $54,435 paid nothing, while someone earning $54,436 suddenly owed $544. Under the new system, someone earning $67,001 pays just 15 cents.

This is a genuine improvement to fairness. It means people are no longer penalised for small income increases, and there is no incentive to artificially keep income below the threshold through salary sacrifice or other arrangements.

Indexation: How Your Debt Grows Each Year

HELP debt does not accrue interest like a bank loan, but it is indexed each year on 1 June to account for inflation. This is the mechanism that caused outrage in 2023 when debts were indexed by 7.1%, the highest rate in the scheme’s history, wiping out years of repayments for some borrowers.

The New Indexation Cap

In response to the 2023 backlash, the government changed the indexation formula. From 2023 onwards, HELP debt is indexed at the lower of CPI or the Wage Price Index (WPI). This means your debt will never grow faster than wages, ensuring that repayments always make meaningful progress against the balance.

For 2026:

• CPI (forecast): approximately 3.5% to 4.0%
• WPI (forecast): approximately 3.2% to 3.6%
• Expected indexation rate: 3.2% to 3.6% (the lower WPI figure)

On a $30,000 debt, 3.4% indexation adds $1,020 to your balance. Under the old CPI-only system, the same debt might have been indexed at 3.8% ($1,140), so the cap saves approximately $120 per year in this example.

Historical Indexation Rates

The cap has made a meaningful difference. Without it, the 2024 indexation would have been 5.8% (CPI) rather than 4.7% (WPI), adding an extra $330 to a $30,000 debt.

Strategic Considerations for 2026

Should You Make Voluntary Repayments?

The short answer for most people: probably not. Here is why.

HELP debt is indexed at approximately 3.2% to 3.6% in 2026. Meanwhile:

• High-interest savings accounts are offering 4.5% to 5.5%
• Term deposits are offering 4.5% to 5.25%
• The RBA cash rate is 4.10%

If you put $10,000 into a high-interest savings account at 5.0%, you earn $500 in a year. If you use that same $10,000 to pay down HELP debt, you save approximately $340 in avoided indexation. You are $160 better off keeping the cash in savings.

The voluntary repayment discount (which used to offer a 5% bonus on voluntary payments above $500) was abolished in 2017. Without that incentive, there is very little financial reason to prioritise HELP debt over other uses of your money.

Exceptions where voluntary repayment might make sense:

• You are about to apply for a mortgage and want to maximise borrowing capacity
• You are close to paying off the debt entirely (under $5,000 remaining)
• You are moving overseas and want to simplify your tax obligations
• You have a strong psychological preference for being debt-free

Impact on Mortgage Borrowing

HELP debt does not appear on your credit report, but lenders absolutely factor it into serviceability assessments. Your compulsory repayment is treated as a fixed expense, reducing how much you can borrow.

Under the new marginal system, repayments are lower for many income levels, which slightly improves borrowing capacity:

For first home buyers earning around the threshold ($67,000 to $80,000), the new system provides a small but welcome boost to borrowing capacity at a time when every dollar counts.

Salary Sacrifice and HELP Debt

Under the old system, some people used salary sacrifice to keep their repayment income below the threshold and avoid compulsory repayments. With the new marginal system and higher threshold ($67,000 vs $54,435), this strategy is less necessary.

However, salary sacrificing into superannuation still reduces your repayment income because reportable super contributions above the employer’s compulsory SG amount are added back in a different way. Talk to an accountant if you are considering this strategy, the interaction between salary sacrifice, HELP repayments, and the new Division 296 super tax (for high-balance members) adds complexity.

HELP Debt and the Cost of Education in 2026

The 20% reduction addresses the symptom (high balances) but not the underlying cause (rising course costs). Commonwealth Supported Place fees have increased significantly over the past five years, particularly for humanities and social science degrees, which were reclassified as “national priority” courses with varying fee levels under the Job-ready Graduates program.

Current HELP Fee Bands (2026)

A four-year law degree at Band 3 rates costs approximately $47,200 in student contributions. After the 20% reduction, a graduate who had accumulated this amount would see their balance drop to $37,760, saving over $9,400.

A three-year humanities degree at Band 4 costs approximately $48,138, actually more than law due to the Job-ready Graduates fee restructure. This pricing has been criticised for discouraging students from pursuing humanities degrees, though the government has signalled a review may be forthcoming.

What to Do Now

Check Your Balance

Log in to myGov and access the ATO online services portal to see your current HELP balance. The 20% reduction should already be reflected. If it is not, contact the ATO as the reduction should have been applied automatically.

Review Your Withholding

If you work as an employee, check that your employer is withholding the correct amount for HELP repayments under the new marginal system. Updated PAYG withholding tables reflecting the new rates should have been implemented from 1 July 2025. If your payslip still shows the old withholding amounts, raise it with your payroll department.

Plan Around the June Indexation Date

HELP debt is indexed on 1 June each year. If you are considering a voluntary repayment to reduce indexation, it must be received and processed by the ATO before 1 June to have an effect. Given the 3.4% indexation rate, a $50,000 debt would have $1,700 added on 1 June. Paying down $10,000 before that date would save $340 in indexation.

Talk to an Accountant

If you have a large HELP balance, complex income arrangements (multiple income sources, investment income, salary sacrifice), or are planning a major financial decision like buying a home, getting tailored advice from a tax professional is worthwhile.
