How HELP repayments work

HELP repayments are compulsory once your repayment income exceeds the threshold. Your employer withholds repayments from your pay through the PAYG system if they know about your HELP debt. Repayment income includes:

Taxable income
Reportable fringe benefits
Reportable employer super contributions
Net investment losses (added back)

This is usually higher than your taxable income if you salary sacrifice or receive fringe benefits.

20% debt reduction & CPI indexation
20% reduction (1 June 2025): Applies to all outstanding HELP, HECS-HELP, FEE-HELP, VET Student Loans, and other eligible study debts. Automatic — no application needed. ATO will notify you via myGov.
CPI indexation (1 June annually): Your HELP debt is adjusted each 1 June by the Consumer Price Index. Recent rates: 7.1% (2023), 4.7% (2024), 3.2% (2025). In high-inflation years your balance can grow faster than repayments.
Voluntary repayments: No direct discount applies since 2017. However, paying before 1 June reduces the balance before CPI is applied — saving you more over the life of the loan. The calculator models this impact.
FAQ
What changed for HELP repayments in 2025-26?
From 2025-26, HELP repayments switched from a flat rate on total income to a marginal rate system. You now only pay on income above $67,000 (up from $54,435). This means lower repayments for most borrowers, especially those earning under $180,000.
What is repayment income for HELP?
Repayment income includes your taxable income plus reportable fringe benefits, reportable employer super contributions, and any net investment losses (added back). It's usually higher than your taxable income if you salary sacrifice or have fringe benefits.
Do I have to make HELP repayments?
HELP repayments are compulsory once your repayment income exceeds the threshold ($67,000 for 2025-26). They're automatically withheld from your pay if your employer knows about your HELP debt. You can also make voluntary repayments at any time.
Will my HELP debt get a 20% reduction?
Yes, from 1 June 2025, all outstanding HELP, HECS, VET Student Loans, and other eligible study debts receive a 20% reduction. This is automatic - you don't need to apply. The ATO will notify you via myGov.
Should I make voluntary repayments?
HELP debt is interest-free (it only increases with CPI indexation, which was capped at the lower of CPI or WPI from 2023). In most cases, it's better to invest extra money elsewhere rather than make voluntary repayments, unless you want to reduce your debt before applying for a home loan.
How does CPI indexation affect my HELP debt?
Your HELP debt is indexed on 1 June each year based on the Consumer Price Index (CPI). Recent indexation rates were: 7.1% (2023), 4.7% (2024), 3.2% (2025). High indexation can cause your debt to grow faster than your repayments, especially at lower incomes. Use the calculator to see how indexation affects your payoff timeline.
Should I make voluntary HELP repayments?
Since the voluntary repayment bonus was removed in 2017, there is no direct discount for paying extra. However, voluntary payments reduce the balance that gets indexed each June, saving you money over time. Use the calculator's voluntary repayment feature to see exactly how much indexation you would save and how many years earlier you could pay off your debt.
