Should You Pay Off Your HECS-HELP Debt Early?

Short answer

Whether paying off your HECS/HELP debt early is worthwhile depends on what your cash needs to do next. An early repayment can make sense when you have a solid emergency buffer, no more expensive debt, and have compared the alternatives. Otherwise, protecting your cash is usually the safer move. To reduce the next annual indexation, a payment must also be received and processed before 1 June.

Key facts

The table below covers the FY2026–27 HELP repayment thresholds and indexation rules (1 July 2026 to 30 June 2027).

Is your HELP repayment income the same as your salary?

Many people assume HELP repayments are simply a percentage of their annual salary. The ATO actually uses repayment income, which is not the same as the gross salary on your payslip.

Repayment income includes taxable income excluding assessable FHSS released amounts, plus reportable fringe benefits, total net investment losses including net rental losses, reportable super contributions, and exempt foreign employment income. That means salary-sacrificed super and investment losses can be added back, so they do not necessarily reduce your HELP repayment income.

This is why some people with a modest salary still end up with a HELP shortfall at tax time. If you are still getting your head around how Australian income tax and HELP interact, it is worth reading our guide to how Australian tax brackets work and, if you salary sacrifice, what salary sacrifice actually means.

How are FY2026–27 compulsory repayments calculated?

The ATO has published updated thresholds for FY2026–27. Do not reuse last financial year's numbers.

Assume your FY2026–27 repayment income is $80,000, your HELP balance is ample, and no exemption applies:

• The amount over $69,528 is $80,000 − $69,528 = $10,472
• At 15%, the compulsory repayment is $10,472 × 15% = $1,570.80

The common mistake is multiplying $80,000 by 15%, which would give $12,000. That is wrong. HELP repayments use a tiered marginal calculation. Only the top tier, from $186,051, is calculated as 10% of total repayment income.

Also note that $1,570.80 is only the HELP compulsory repayment. It does not include your income tax or Medicare levy. At tax time those are calculated separately.

Does a $5,000 voluntary repayment replace compulsory repayments?

This is easily misunderstood. The ATO's voluntary repayment guidance explains that partial voluntary repayments do not directly replace or offset compulsory repayments. If debt remains and your repayment income exceeds the threshold, a compulsory repayment may still be due. The actual amount also depends on the remaining debt and any applicable exemption.

Using the earlier example, suppose you voluntarily pay $5,000 in April 2027, still owe more than $1,570.80 afterwards, and have no exemption. The income-based compulsory repayment remains $1,570.80; the $5,000 separately reduces your debt. If the remaining debt is smaller than the income-based calculation, do not assume this example's full amount would still be payable.

Full payoff is different. The ATO recommends having a total payoff credited before lodging your return or worldwide income. With no outstanding loan at assessment, there is no new compulsory repayment against that cleared debt. Lodge before the payment is credited and a compulsory repayment may first appear on your notice of assessment. Check any already-assessed amounts separately rather than relying only on a bank transfer receipt.

Why can an interest-free HELP balance still grow?

HECS/HELP does not charge interest, but every 1 June the loan balance is indexed. The adjustment uses the lower of CPI or WPI, and only applies to loan amounts more than 11 months old. The next indexation is 1 June 2027.

What matters is whether the payment has been received and processed before indexation, and which remaining loan amounts qualify for indexation. A timely voluntary repayment can reduce the indexed amount. A payment credited after 1 June cannot reverse that year's indexation, though it reduces the outstanding balance going forward.

The ATO notes electronic and Australia Post payments can take up to 4 business days to appear in your account. If you want to reduce the balance before indexation, do not transfer on the last day. Processing time depends on the payment method, and the ATO does not guarantee same-day credit.

Should you repay HELP or keep cash in your mortgage offset?

This is the real dilemma for many Australian households: you have $5,000 or $10,000 spare. Should it go to HELP, or stay in the mortgage offset account?

Here is a teaching example to illustrate the logic, but it is not a forecast.

Assume the 1 June 2027 indexation rate is 3% (purely hypothetical, not an ATO figure or prediction). If you repay $5,000 before indexation, that $5,000 is not indexed, so you avoid $5,000 × 3% = $150 of balance growth. That is a one-off effect on the indexation date.

Now assume a 6% home loan rate, also hypothetical and not a market quote. Keeping $5,000 in an eligible full offset for a full year would save roughly $5,000 × 6% = $300 in gross loan interest. This assumes sufficient loan debt, unchanged balances and rate, and the cash staying there all year. It is before incremental fees or rate differences, not a net saving promise. Our offset account guide explains the account mechanics.

These figures are not a personal forecast: one measures a single indexation event, the other a full year of mortgage interest. A shorter time in the offset means less interest saved. The $150 only follows if the assumed 3% applies, that loan portion would otherwise be indexed, and payment is processed in time. Compare the same time horizon using the published indexation rate and your actual loan terms.

So my advice is not to decide based on which number looks bigger. Ask yourself three questions first:

1. Do you have enough emergency cash? If you repay this money and then need to fix the car, pay a childcare deposit, or cover an income gap, will you be stretched?
2. Do you have more expensive debt? Check the actual interest and fees on credit cards, personal loans, or other balances. Higher-cost debt usually deserves attention first; do not judge cost by the product name alone.
3. Will you need this money within the next 12 months? Voluntary repayments are not a savings account you can withdraw from if you change your mind. That is different from any separate statutory account credit or refund.

Why has your HELP balance not fallen despite payroll deductions?

Many people assume the extra HELP withholding their employer takes from each pay is already reducing their loan. It is not.

The ATO explains the compulsory repayment and withholding process: tell each employer about your study loan. Extra PAYG withholding goes to the ATO, but is not applied against HELP after each pay cycle. It is applied after you lodge your return and the ATO calculates the compulsory repayment.

So if you log into myGov and your loan balance has not moved, that is normal.

PAYG withholding is also only an estimate. If you have other income such as rent, investment income, or freelance work, your final compulsory repayment may be higher than what was withheld, creating a shortfall at tax time. This is why many people receive a bill after lodging.

If you have fully paid off the loan, submit an updated Withholding declaration to your employer so the HELP withholding can stop, and confirm in myGov that the loan account balance is zero.

When does an early repayment actually make sense?

Here is a simple checklist:

• ✅ You have checked your actual loan balance in myGov and know what remains
• ✅ You have a solid emergency buffer, and repaying will not strain day-to-day spending
• ✅ You have no credit card, personal loan, or other high-interest debt
• ✅ You know roughly what this year's compulsory repayment will be and have set aside cash for any tax shortfall
• ✅ You have compared the opportunity cost of keeping the money in an offset account
• ✅ You have confirmed the payment reference and processing time, and can get the funds credited before indexation

If all of the above are true, an early repayment is a reasonable choice. If any one of them is not, especially the emergency cash test, I would hold off.

How does full payoff differ from a partial repayment?

It is worth separating these two situations.

Partial repayment reduces the debt and potentially future indexation. It does not directly offset an income-based compulsory repayment; the final assessment still depends on the remaining debt and your applicable rules.

Full payoff clears the remaining debt. Confirm the ATO has credited it before lodging, check any already-assessed amounts, then update your employer's withholding declaration after discharge. Draining your emergency buffer to clear HELP and then borrowing expensive money for a car repair or income gap can be a poor trade.

Some people ask whether clearing HELP will help them borrow more for a home loan. The answer varies by lender. Different lenders assess HELP debt differently: some include it in total liabilities, others focus more on cashflow. If you are buying soon, ask your own lender or broker before making a final payoff. Do not assume clearing HELP automatically increases your borrowing capacity by a specific amount.

What can you do this week?

As a CPA, and as someone who puts household financial safety first, my order of priority is always:

1. Emergency cash
2. Expensive debt
3. Optional repayments and other longer-term plans

Do not confuse interest-free with an unchanged balance, or treat the next indexation rate as already known. Start by opening myGov, then ATO online services: Tax → Accounts → Loan accounts. Check the balance, transactions and payment reference, then estimate your FY2026–27 repayment income before moving money.

Extra voluntary repayments are a choice; compulsory repayments must still be dealt with when due. What matters is understanding what you give up by paying early and which household needs keeping the cash would protect.
