HECS-HELP Repayment Guide 2025-26 — New System Explained

What Is HECS-HELP?

HECS-HELP is the Australian Government's income-contingent loan scheme that covers tuition fees for eligible Commonwealth-supported university students. The acronym stands for Higher Education Contribution Scheme – Higher Education Loan Program.

Approximately 3 million Australians hold an active HECS-HELP debt as of FY2025-26, with the average outstanding balance sitting at roughly $26,500. The loan carries no commercial interest rate. Instead, the balance is indexed annually to maintain its real value against inflation, using the lower of the Consumer Price Index (CPI) or the Wage Price Index (WPI).

Repayments are compulsory once your “Repayment Income” (RI) exceeds $67,000 in FY2025-26. Repayment Income includes your taxable income, total net investment losses, reportable fringe benefits, and reportable superannuation contributions. This broader definition prevents high earners from sheltering income through salary sacrifice or negative gearing to avoid HECS obligations.

The scheme operates through the Australian tax system. Your employer withholds HECS repayments from each pay cycle via PAYG withholding, and the ATO reconciles the total when you lodge your annual tax return. Use our Income Tax Calculator to see how HECS fits alongside your income tax brackets and Medicare levy.

How Do HECS Repayments Work?

HECS repayments are deducted automatically from your salary through the PAYG withholding system, calculated as a percentage of income above the $67,000 minimum threshold.

The repayment process follows 5 steps:

1. Notify your employer — Tick the “HELP/SSL/TSL debt” box on your Tax File Number (TFN) declaration when starting a new job. Your employer then applies additional withholding each pay cycle to cover compulsory repayments.
2. Employer withholds HECS — Your employer deducts HECS repayment amounts from your gross pay alongside PAYG tax. The exact weekly or fortnightly amount depends on your salary level and the ATO's PAYG withholding schedules.
3. Lodge your tax return — When you lodge your return after 30 June, the ATO calculates your actual Repayment Income for the financial year. This determines your true compulsory repayment obligation.
4. ATO reconciles — The ATO compares what your employer withheld against what you actually owe. Any shortfall is added to your tax bill. Any excess is refunded as part of your tax return.
5. Balance reduces — Confirmed repayments are applied to your HECS-HELP balance. You can track your remaining debt through your myGov account linked to the ATO.

The PAYG withholding tables your employer uses are updated each financial year. See our PAYG Withholding Tables guide for the complete FY2025-26 schedule. If you earn income from multiple employers, each withholds independently, so you may end up under- or over-paying during the year.

What Are the HECS-HELP Repayment Thresholds for FY2025-26?

The minimum repayment threshold for FY2025-26 is $67,000, a significant increase from the previous threshold of $54,435 under the old flat-rate system.

Under the new marginal system introduced from 1 July 2025, repayment rates apply only to income within each band — not to your entire salary. This structure mirrors how Australian income tax brackets work, eliminating the harsh “cliff” effects of the old system.

The $67,000 threshold represents approximately 75% of average graduate earnings, ensuring that lower-income graduates retain more take-home pay during the early years of their careers. Graduates earning below this threshold — including many teachers, nurses, and social workers in their first few years — make zero compulsory HECS repayments.

How Does the Marginal System Differ from the Old Flat-Rate System?

The old system applied a single percentage to your entire repayment income once you crossed a threshold. Earning $1 over the boundary triggered a repayment on your full salary, creating punishing cliff edges where a small pay rise resulted in a net pay decrease.

How Are HECS Repayments Calculated?

HECS repayments are calculated by applying the marginal rate to each dollar of repayment income above the $67,000 threshold, following the same band-based logic as Australian income tax.

How Does HECS Affect Take-Home Pay?

HECS repayments reduce your after-tax income by $37.50 per week at an $80,000 salary, scaling progressively as income rises under the new marginal system.

The table below shows the full impact across 8 common salary levels, including the annual HECS obligation, weekly deduction, and resulting net take-home pay after income tax, Medicare levy, and HECS are all removed.

Notice how there's no sudden jump in repayments under the new marginal system. Moving from $67,000 to $70,000 only triggers $450 in annual HECS — just $8.65 per week. Under the old flat-rate system, that same earner would have faced a much larger cliff. Use our HECS-HELP Calculator to model your exact scenario.

How Is HECS Debt Indexed?

HECS debt is indexed on 1 June each year at the lower of the Consumer Price Index (CPI) or the Wage Price Index (WPI), capping annual growth to prevent inflation spikes from ballooning student loan balances.

The Australian Government does not charge commercial interest on study and training loans. Instead, debts are adjusted annually to maintain their real purchasing-power value. The indexation rate for the 12 months to March of the relevant year is applied to your outstanding balance on 1 June.

In 2023, high inflation caused a historic indexation spike of 7.1%, adding thousands of dollars to loan balances across the country. A graduate with a $30,000 debt saw it jump by $2,130 overnight. To protect graduates from this happening again, the government legislated a new capped formula:

Indexation = the lower of CPI or WPI. This was backdated to 1 June 2023.

Historical Indexation Rates

The backdated correction for 2023 wiped out the 7.1% spike and retroactively applied the lower 3.2% WPI rate. Graduates who overpaid as a result of the inflated 2023 indexation received credits to their HECS balance. This change benefited approximately 3 million borrowers and reduced total outstanding HELP debt by roughly $3 billion.

Is It Worth Paying Off HECS Early?

Voluntary HECS repayment is financially advantageous only when indexation exceeds the after-tax return you could earn by investing that money elsewhere — for most graduates in FY2025-26, this means early repayment is not the optimal strategy.

HECS carries no commercial interest. The debt grows only by the indexation rate, which is capped at the lower of CPI or WPI — currently around 2.4%. A standard high-interest savings account offers 4.5–5.0% returns before tax. Even after the 16–39% marginal tax on interest income, the net return exceeds HECS indexation in most scenarios.

When Voluntary Repayment Makes Sense

• Your balance is small — If you owe less than $5,000, clearing it removes the administrative burden and frees up cash flow permanently.
• You are about to go overseas — HECS obligations still apply to Australian residents earning abroad. Clearing the debt before departure eliminates the need to lodge Australian returns for HECS purposes.
• Indexation is high — In years where CPI exceeds 4–5%, early repayment provides a guaranteed “return” equal to the avoided indexation rate.
• You have surplus cash with no higher-return use — If the money would otherwise sit in a 0% transaction account, paying down HECS avoids the guaranteed indexation cost.

If you do make a voluntary repayment, lodge it via BPAY to the ATO before 1 June to reduce your balance before indexation is applied. There are currently no government bonuses or percentage discounts for voluntary payments — the sole benefit is principal reduction.

Consider whether salary sacrifice into superannuation provides a better long-term outcome. Read our Salary Sacrifice Guide for a comparison of pre-tax strategies.

What Types of Australian Study Loans Exist?

Australia operates 4 distinct government study loan schemes: HECS-HELP, FEE-HELP, VET Student Loans, and SA-HELP, each covering different study types and fee structures.

All 4 loan types share the same repayment thresholds, marginal rates, and indexation rules. The ATO combines your HECS-HELP, FEE-HELP, VET Student Loan, and SA-HELP debts into a single “HELP balance” for repayment purposes. A graduate with a $20,000 HECS-HELP debt and a $5,000 SA-HELP debt makes repayments against the combined $25,000 total.

FEE-HELP carries a 20% loan fee on undergraduate courses, meaning a $10,000 tuition charge results in a $12,000 debt. This fee does not apply to postgraduate courses, HECS-HELP, or SA-HELP. VET Student Loans also attract the 20% fee, capping the effective debt at $6,000 – $18,000 depending on the course band.

What Changed in FY2025-26?

FY2025-26 introduced 3 structural reforms to Australian study loans: the marginal repayment system, a raised minimum threshold, and permanently capped indexation.

These changes stem from the Universities Accord (Student Support and Other Measures) Bill 2024, which passed Parliament following the Australian Universities Accord Final Report. The reforms represent the most significant overhaul of the student loan system since HECS was introduced in 1989.

The combined effect of these changes is that a graduate earning $80,000 saves approximately $1,650 per year in compulsory repayments compared to the old system. Graduates earning below $67,000 — previously subject to repayments under the lower threshold — now pay nothing.

These reforms also affect how HECS interacts with other elements of your pay. The reduced HECS withholding increases your net pay, which in turn changes your effective marginal tax rate calculations. Use our Income Tax Calculator alongside the HECS-HELP Calculator for a combined view.

What Are the Key HECS-HELP Dates and Deadlines?

The most critical HECS date is 1 June, when annual indexation is applied to all outstanding balances. Missing this date with a voluntary payment means your entire balance is indexed before any reduction.

Census dates for university enrolment vary by institution and teaching period. Students who withdraw before the census date incur no HECS liability. Withdrawing after the census date means the full subject fee is added to your HELP balance. Check your university's academic calendar for specific census dates each semester.
