HECS-HELP is Australia’s income-contingent student loan system, administered by the ATO. Unlike a bank loan, you pay nothing until your income crosses a minimum repayment threshold — and there is no interest, though the debt is indexed to CPI each year. Once your income reaches the threshold, your employer withholds an additional amount from your wages and the ATO applies it to your HECS balance when you lodge your tax return.

This cluster covers everything you need to know about HECS-HELP: the current repayment thresholds and rates, how indexation works and what it cost borrowers in recent years, voluntary repayments, and what happens to your HECS debt if you move overseas.

HECS Repayment Rates — FY2025–26

Once your income exceeds the minimum repayment threshold ($54,435 in FY2025–26), the ATO requires a compulsory repayment as a percentage of your repayment income (roughly your taxable income plus certain reportable fringe benefits and investment losses).

Rates updated for FY2025–26. The ATO reviews thresholds annually in line with average wage growth.

Your employer withholds the estimated HECS repayment from your wages once you notify them via your TFN declaration that you have a HECS debt. Any shortfall or overpayment is reconciled when you lodge your tax return.

How HECS Indexation Works

On 1 June each year, the ATO applies a CPI-based indexation factor to all outstanding HECS-HELP (and other HELP loan) balances. This is not interest — it is an inflation adjustment designed to maintain the real value of the debt.

Recent indexation rates and their effect on a $30,000 balance:

Financial yearCPI indexation rateAdded to $30,000 balance
FY2020–210.6%$180
FY2021–223.9%$1,170
FY2022–237.1%$2,130
FY2023–244.7%$1,410
FY2024–252.7%$810

The 7.1% indexation in FY2022–23 added over $2,000 to a $30,000 balance in a single year — larger than the compulsory repayment for many graduates. This triggered significant public debate and ultimately led to a government policy of capping indexation at the lower of CPI or the Wage Price Index from FY2025–26.

HECS and Your Tax Return

Your HECS repayment does not appear as a separate item on your payslip in most cases — it is rolled into your PAYG withholding. When you lodge your tax return via myTax, the ATO automatically calculates your compulsory repayment based on your repayment income and applies it to your balance. You do not need to calculate this yourself.

You can view your current HECS balance via myGov → ATO online services → Loans → Study and training loan account.

Frequently Asked Questions

Does my HECS debt affect my credit score?

No. HECS-HELP debt does not appear on your credit file with Equifax, Experian, or illion. Lenders cannot see your HECS balance through the credit bureau. However, lenders do consider your HECS repayments as a committed expense when assessing your borrowing capacity — reducing the loan amount you can qualify for.

Can I pause HECS repayments if I am unemployed?

HECS repayments are automatically paused when your income falls below the repayment threshold. If you are unemployed or your income drops, no compulsory repayment applies for that financial year. You can still make voluntary repayments at any time via BPAY.

What happens to HECS debt if I die?

HECS-HELP debt is cancelled upon the borrower’s death. It does not pass to a spouse or estate. The ATO cancels the balance on notification of death and the debt is extinguished — it is not recoverable from the deceased’s estate.

HECS-HELP and Your Home Loan Borrowing Capacity

HECS-HELP debt affects your home loan borrowing capacity even though it doesn’t appear on your credit file. Lenders are required to assess your ability to service a loan considering all committed expenses — and HECS repayments are treated as a committed monthly outgoing.

How lenders calculate the HECS impact:

Lenders use your HECS repayment income to estimate your annual compulsory repayment, then convert it to a monthly reduction in available serviceability income.

HECS balanceGross incomeAnnual compulsory repayment (FY2025)Monthly reduction
$30,000$90,000~$4,500 (5.0%)~$375/month
$50,000$90,000~$4,500 (5.0%)~$375/month
$80,000$110,000~$7,150 (6.5%)~$596/month

The balance of the HECS debt matters less to lenders than the income-based repayment amount. A $30,000 balance and an $80,000 balance on the same income produce the same monthly repayment impact.

At a 6% interest rate, a ~$375/month reduction in serviceability income typically reduces borrowing capacity by approximately $55,000–$65,000.

Can you pay off HECS before applying for a mortgage to increase borrowing capacity?

Yes — if you have sufficient savings. If paying off HECS means you have less deposit (and trigger LMI or cross into a higher LMI tier), the calculation is not straightforward. Paying $40,000 HECS debt to increase borrowing capacity by $60,000 may be worthwhile — or the $40,000 is better used as deposit to avoid LMI. Model the specific numbers with a mortgage broker.

Voluntary HECS Repayments

There is no bonus for making voluntary repayments (the 5% voluntary repayment bonus was abolished in 2017). However, voluntary repayments reduce your outstanding balance permanently, lowering future compulsory repayments and eliminating the debt sooner.

You can make voluntary HPAY repayments at any time via BPAY (BPAY biller code and reference on your ATO online services account). There is no minimum or maximum voluntary repayment amount.

HECS-HELP for Overseas Australians

If you move overseas, your HECS-HELP obligation does not disappear. From 1 January 2016, Australians living and working overseas are required to make compulsory HECS repayments based on their worldwide income (converted to AUD at the ATO’s exchange rate).

You must complete a Worldwide Income Assessment each year you live overseas if your worldwide income exceeds the repayment threshold. Failure to report can result in an estimated assessment (which may exceed your actual liability) and penalties.

Voluntary repayments from overseas are accepted via BPAY or direct bank transfer to the ATO. The ATO monitors outstanding HECS balances and enforces collection on return to Australia if repayments were not made while abroad.
