How HELP and HECS repayments come out of your pay

HECS, HELP and the other study loans are one repayment system

HECS is the historical name. The Higher Education Contribution Scheme became the Higher Education Loan Program in 2005, and what most people still call a HECS debt is now a HECS-HELP debt. Around it sit FEE-HELP, OS-HELP, SA-HELP, VET Student Loans, Australian Apprenticeship Support Loans and a few others.

For repayment purposes the distinction barely matters. The ATO treats study and training support loans as one accumulated balance with one set of thresholds. If you hold two kinds of loan you do not get two thresholds, and repayments are applied across the balance rather than to a particular loan you choose.

The repayment is income-contingent. It is not a fixed monthly instalment and there is no schedule, no minimum payment and no default. What you repay in a year is determined entirely by what you earned in that year, and if you earn little enough you repay nothing at all.

The 2026–27 repayment thresholds

There are four bands. The first three behave the way income tax brackets do — a rate on the income above a threshold — and the fourth does something different, which the next section deals with properly.

Because the first band is marginal, there is no cliff at the bottom. Repayment income of $69,528 produces nothing; one dollar more produces fifteen cents. That is a deliberate design choice, and it is the opposite of how the Medicare levy surcharge behaves — see the Medicare levy guide for the contrast.

The top band applies to everything — and still does not create a jump

This is the part of the schedule that confuses people, and it is worth spending a paragraph on because the structure genuinely is inconsistent. The first two bands charge a rate on the excess over a threshold. The top band charges 10% of total repayment income, with no threshold subtracted.

First band:   15% × (income − $69,528)
Second band:  $9,028.35 + 17% × (income − $129,717)
Top band:     10% × income          ← the whole lot, not the excess

Read literally, that looks like it should produce an enormous cliff. It does not, because the numbers are constructed to meet. Two arithmetic checks show why.

1. The second band’s base of $9,028.00 is not a round figure someone picked. It is exactly 15% of the $60,189 between $69,528 and $129,717, which is what the first band would have accumulated by the time you reach the top of it. The first two bands are therefore continuous: the second one picks up precisely where the first one stopped.
2. At $186,050, the second band gives $9,028.00 + 17% × $56,333 = $18,604.96. Ten per cent of the same total income is $18,605.00. The two formulas differ by four cents. The changeover is smooth.

So the top band is not a penalty and it is not a trap. What it does change is the marginal rate: below $186,051 each extra dollar of repayment income adds 17c to your repayment, and above it each extra dollar adds only 10c. The schedule flattens out at exactly 10% of income and stays there no matter how much you earn.

Repayment income is not the same as your salary

Every threshold above is tested against repayment income, which the ATO builds from taxable income and then adds several things back to. For most salaried people with no other arrangements, repayment income and taxable income are close enough that salary is a reasonable estimate. For everyone else the difference matters.

• Reportable fringe benefits, such as a novated lease on a car provided through work.
• Reportable employer superannuation contributions, which is the salary sacrifice you arranged above the compulsory rate.
• Total net investment losses, including the loss on a negatively geared property.
• Exempt foreign employment income.

The practical consequence catches people out regularly: salary sacrificing into super lowers your taxable income and your income tax, but it is added straight back for study loan purposes. So it does not reduce your compulsory repayment. The same is true of negative gearing.

Why your employer’s withholding is only an estimate

When you tick the study loan box on your tax file number declaration, your employer starts withholding an additional amount from each pay under the ATO’s Schedule 8 withholding tables. That extra money is not sent to your loan. It goes to the ATO as ordinary PAYG withholding and sits in the same pool as the rest of your tax.

The actual compulsory repayment is calculated once, when your return is assessed, from your repayment income for the whole year. Only then is it applied to your loan balance. Your total withholding for the year is compared against your total tax plus that repayment, and the difference is your refund or your bill.

Why the two figures diverge

• Withholding annualises each pay in isolation. A large bonus fortnight is withheld as though every fortnight looked like that, so too much comes out.
• A second job, bank interest, dividends or a capital gain add to repayment income but were never seen by the employer doing the withholding.
• Salary sacrifice and reportable fringe benefits are added back into repayment income after the fact, raising the assessed repayment above what was withheld.
• Starting or finishing work partway through the year leaves the withholding calibrated for an annual income you never actually earned.

Indexation, voluntary repayments and what kind of debt this is

A HELP debt is not a commercial loan and comparing it to one leads people astray in both directions. There is no interest rate, no fixed term, no minimum monthly payment, no lender who can call it in, and it does not appear as a liability the way a personal loan does. Nothing happens if your income falls and your repayments stop.

What does happen is indexation. Once a year the outstanding balance is adjusted so that it keeps pace with movements in prices. The indexation figure is set annually and published by the ATO, so check the current rate there rather than assuming last year’s. Because indexation applies to the balance and the year’s compulsory repayment is only credited when your return is assessed, a balance can look as though it barely moved despite thousands of dollars being repaid.

Voluntary repayments can be made at any time and in any amount, on top of whatever compulsory repayment is assessed. They reduce the balance immediately, which reduces what gets indexed next time. Whether that is a good use of the money is a real question rather than a rhetorical one: the debt has no interest, no repayment pressure and no effect on your credit file, so the case for clearing it early is weaker than for almost any other debt you might hold. It does, however, reduce your take-home pay for as long as it lasts, which is the cost people actually feel.

For where that reduction sits relative to income tax and the Medicare levy in a single pay cycle, work through how Australian take-home pay is actually calculated. For the income tax rates the repayment sits alongside, see the income tax brackets guide.

What the OzCalc HELP calculator does and does not model

The HELP and HECS repayment calculator takes a repayment income and an income year and applies the four bands above, returning the compulsory repayment and its effective rate. It is the year-end assessment figure — the number the ATO would raise on your return — not the extra amount your employer withholds each pay.

It does not know your loan balance, and it assumes the balance is at least as large as the compulsory amount. In your final year of repayment the assessed amount is limited to what you still owe, so the calculator will overstate it. It does not calculate repayment income for you: if you have reportable fringe benefits, salary sacrifice or an investment loss, you need to add those back yourself before entering a figure. It does not apply indexation, model voluntary repayments, or track a balance over time.

If you want the payslip view instead — how much extra comes out each fortnight while the loan lasts — the salary calculator and the PAYG estimator work in withholding terms, and the income tax calculator can add the repayment to a full year-end estimate.
