When we advise a tax filing student with HECS-HELP debt, we look beyond wages to the income measures that determine compulsory repayments. Part-time employment, investment income, salary packaging and an ABN side business can all change the final assessment. For business owners employing students, or families supporting a working university student, the practical issue is the same: payroll withholding may not cover the eventual liability.
We explain the rules below using the 2025-26 income year, which is generally being lodged in 2026. We distinguish that return from income earned after 1 July 2026, which belongs to 2026-27.
HECS-HELP affects the assessment, not just the refund
We separate three amounts when reviewing a student's position: ordinary income tax, any Medicare levy liability and the compulsory HELP repayment. Having a HECS-HELP debt does not create a separate income tax rate or make student workers exempt from normal tax obligations.
The ATO calculates a compulsory repayment when repayment income exceeds the applicable threshold and an eligible loan balance remains. That repayment forms part of the tax assessment. It can reduce an expected refund or contribute to an amount payable.
We also distinguish payroll deductions from actual loan repayments. Additional PAYG withholding collected because an employee has a HELP debt goes to the ATO as withholding credits. It does not ordinarily reduce the loan balance each payday; the compulsory repayment is calculated through the assessment process.
Our broader explanation of Australian tax rules for casual student workers covers employment and residency issues. Here, we focus on the HELP calculations that can change the outcome.
The 2025-26 repayment thresholds and marginal calculation
For a tax filing student preparing a 2025-26 return, we apply the new marginal repayment system rather than the percentage-of-total-income approach used in earlier years. Under the new rules, repayments initially apply only to income above the threshold.
The ATO's study and training loan repayment thresholds set out these bands:
| Repayment income for 2025-26 | Compulsory repayment calculation |
|---|---|
| $67,000 or less | Nil |
| $67,001 to $125,000 | 15 cents for each dollar above $67,000 |
| $125,001 to $179,285 | $8,700 plus 17 cents for each dollar above $125,000 |
| $179,286 and above | 10% of total repayment income |
These calculations are subject to the remaining repayable loan balance and any applicable assessment adjustments.
A worked example
We can illustrate the calculation with a hypothetical worker whose repayment income is $80,000 and whose outstanding debt exceeds the calculated repayment:
($80,000 minus $67,000) × 15% = $1,950.
That $1,950 is the compulsory HELP repayment, not the worker's total tax bill. Ordinary income tax and other applicable amounts are calculated separately, then withholding credits are applied to the assessment.
We do not reuse these thresholds for 2026-27 payroll forecasts. For income earned from 1 July 2026, we check the corresponding ATO thresholds and withholding schedules.
What counts as repayment income for a tax filing student?
We calculate HELP repayment income separately from taxable income. The distinction matters because several amounts excluded from, or deducted in calculating, taxable income are added back for HELP purposes.
The ATO's study and training support loan guidance identifies the relevant components:
| Component | Treatment in the repayment-income calculation |
|---|---|
| Taxable income | Included, after allowable deductions |
| Reportable fringe benefits | Added to taxable income |
| Reportable superannuation contributions | Added to taxable income |
| Total net investment loss | Added back, including relevant rental losses |
| Exempt foreign employment income | Included where applicable |
We therefore avoid estimating repayments from a payslip alone. Investment schedules, superannuation records and reportable benefit amounts can materially change the calculation.
Salary packaging and superannuation
Salary packaging can lower taxable salary without producing an equivalent reduction in HELP repayment income. Reportable fringe benefits, including benefits provided by certain FBT-exempt employers, can still enter the calculation.
Similarly, reportable superannuation contributions can include salary-sacrifice contributions and deductible personal contributions. Ordinary compulsory employer superannuation contributions are generally not reportable contributions merely because the employer pays them.
For a tax filing student considering salary sacrifice, we compare the income tax benefit with the HELP add-back before recommending a cash-flow strategy. In a hypothetical case, $65,000 of taxable income plus $10,000 of reportable superannuation contributions produces repayment income of $75,000, assuming no other adjustments. The 2025-26 compulsory repayment would then be $1,200, subject to the remaining debt balance.
Side businesses and investments
We include the taxable net profit from an ABN side business, not simply the amount transferred from its bank account. Freelance design, tutoring, content creation and consulting income can increase the annual repayment even when wages alone remain below the threshold.
We also review taxable investment income, including dividends, interest and taxable capital gains. Relevant net investment losses are added back, so a rental loss does not necessarily reduce HELP repayment income in the way it reduces taxable income.
For student directors, we distinguish company turnover from personal income. Salary, dividends and other amounts entering an individual's assessment matter; company revenue is not automatically the director's repayment income.
Why PAYG withholding can leave a shortfall
We recommend checking the HELP declaration with every employer. Employees should accurately disclose their study loan position through the relevant TFN declaration or withholding declaration and update it when circumstances change.
Even correctly configured payroll can leave a shortfall. Each employer generally calculates withholding using the wages it pays, without complete visibility over earnings from other employers, investments or a side business.
A worker with two jobs may therefore have combined repayment income above the annual threshold even though each payroll stream appears modest. Conversely, high withholding during a short period of employment can exceed the final annual requirement.
For a tax filing student with variable earnings, we prepare a whole-year estimate rather than treating each payslip as a complete forecast. We compare expected repayment income, ordinary tax and available PAYG credits, then consider additional withholding or a separate cash reserve where appropriate.
Annual assessment and payroll use different information
Bonuses, irregular shifts and reportable benefits can make the payroll estimate differ from the annual assessment. We reconcile final income statements and reportable amounts before relying on the forecast.
We also distinguish a compulsory repayment from voluntary payments. An extra payment directly to the HELP account does not ordinarily replace the compulsory repayment calculated at tax time unless it clears the relevant outstanding balance before that calculation. We check the timing and account position before advising on this strategy.
Employer payroll controls support better financial planning
For business owners, accurate student-worker payroll is a compliance responsibility and a foundation for strategic advisory. We check employee declarations, current withholding settings and reportable benefits before treating payroll costs and employee deductions as reliable management information.
We keep superannuation obligations separate from HELP withholding. Employment status also requires its own assessment: holding an ABN does not, by itself, make a worker an independent contractor. For genuine contractors, income tax and HELP provisions need to be managed outside employee payroll.
Our AI-driven approach supports faster record reconciliation, greater accuracy and more timely financial visibility. We combine automation with professional review rather than assuming that software can resolve incomplete declarations or decide tax treatment independently.
For a growing business, these controls improve cash-flow forecasts and workforce planning. Reliable payroll and bookkeeping give our strategic advisory work a sound base for corporate growth, rather than leaving management decisions dependent on year-end corrections.
Deductions, debt reductions and indexation need separate treatment
We distinguish expenses that reduce taxable income from payments that reduce the loan balance. Compulsory and voluntary HELP repayments are not tax deductions.
Tuition fees financed under HECS-HELP are not deductible. Other self-education expenses may qualify where the required connection to current income-earning activities exists and the relevant rules are satisfied. FEE-HELP has different considerations, so we identify the loan and expense type rather than treating all education debt alike.
Work-related deductions can reduce taxable income when properly substantiated. However, the repayment-income add-backs still need to be applied. We do not assume that every reduction in taxable income delivers an equal reduction in compulsory repayments.
For a tax filing student reviewing an ATO account, we also reconcile the legislated one-off 20% reduction applying to eligible loan balances at 1 June 2025 and any associated indexation adjustments. This is a balance adjustment, not an annual discount or a tax deduction.
Indexation also changes the debt balance rather than the repayment-income threshold. We confirm the current balance before recommending a voluntary repayment, particularly where the debt is close to being cleared.
Turn the repayment estimate into a financial-health plan
We treat HELP as part of after-tax cash-flow planning, not as an isolated lodgement issue. For families, directors and professionals building assets, the useful figure is the amount available after tax, compulsory repayments and essential commitments.
We assess voluntary repayments against emergency reserves, other debts, planned investments and borrowing objectives. Clearing HELP may improve the position assessed by some lenders, but lender policies differ and repayment is not automatically the best use of available cash.
For a tax filing student preparing to buy property, we distinguish loan balance, annual repayment expense and sustainable income. Our guidance on how a tax refund can support an Australian loan application explains why a refund may strengthen cash reserves without becoming recurring income.
We keep property research separate from Australian financing assumptions. Families comparing local properties or overseas options such as manufactured homes in San Antonio still need an affordability assessment relevant to the market where they intend to borrow. For Australian lending, we use verified income, HELP obligations and the lender's current criteria, not advertised overseas financing arrangements.
Frequently asked questions
Does studying prevent a compulsory HECS-HELP repayment? We apply the repayment-income rules regardless of whether the borrower is still studying. Enrolment alone does not exempt income above the applicable threshold.
Can someone below the repayment threshold still need to lodge? Yes. We assess lodgement obligations separately from HELP. Wages, tax withheld, business activities and other circumstances may require a return even when no compulsory repayment arises.
Does payroll withholding reduce the debt immediately? We treat withholding as a credit against the eventual tax assessment. The HELP balance generally changes when the ATO processes the compulsory repayment, not each time wages are paid.
Can a tax filing student claim HECS-HELP repayments as a deduction? No. We distinguish loan repayments from potentially deductible work-related or self-education expenses. Paying down the debt does not itself create a deduction.
What happens when a borrower moves overseas? We check the ATO's overseas notification and income-reporting requirements. Moving overseas does not automatically remove Australian study loan obligations, and the relevant worldwide-income rules need separate consideration.
