Does HECS affect your borrowing capacity? Yes, through serviceability

A HELP debt shrinks the income lenders count, not your credit score. How serviceability works, what the 2025 regulatory changes did, and what paying the debt off does and doesn't change.

The mechanism: it's an income haircut

When a lender assesses a home loan, the core question is how much income remains after your commitments. Compulsory HELP repayments come straight out of that income: at $100,000 of repayment income in 2026-27, that's $4,571 a year (see the full thresholds table). To a serviceability model, that's equivalent to losing the same amount of salary, which at typical assessment settings can translate to tens of thousands of dollars of borrowing capacity.

Note what a HELP debt is not: it isn't on your credit report, it has no missed-payment risk in the conventional sense, and repayments stop automatically if your income falls below the threshold. It's the repayment flow, not the balance, that lenders price in.

The repayment the lender sees, by income (2026-27)

Lenders work in monthly figures. This is the compulsory HELP repayment at four repayment incomes, converted to the monthly amount a lender counts against you, with and without the APRA 12-month exclusion:

Repayment incomeGross per monthAnnual HELP repaymentMonthly HELP the lender countsShare of gross incomeIf the debt clears within ~12 months
$70,000$5,833$71$60.1%Lender may count $0
$90,000$7,500$3,071$2563.4%Lender may count $0
$120,000$10,000$7,571$6316.3%Lender may count $0
$150,000$12,500$12,476$1,0408.3%Lender may count $0

Monthly HELP is the ATO 2026-27 compulsory repayment divided by 12. How a given lender turns that into a borrowing limit (buffers, living expenses, tax) is its own policy and isn't modelled here. Without HELP, the "monthly HELP" column is $0 at every income.

The pattern: at $90,000 a lender deducts about $256 a month; at $150,000 it is $1,040, or 8.3% of gross income, because more of the income sits above the threshold and the rate rises from 15c to 17c per dollar above $129,717. Just over the $69,528 threshold the deduction is negligible. The balance doesn't appear anywhere in the calculation except in the last column: a small balance is what unlocks the 12-month exclusion.

What changed in 2025

In 2025 the government directed the regulators to stop HELP debts being treated like ordinary loans, and APRA's updated guidance took effect from 30 September 2025. Two changes matter for borrowers:

What clearing the debt changes

Paying out a HELP debt restores the repayment amount to your assessable income and stops the payslip deductions, which lifts both borrowing capacity and take-home pay. Whether that beats keeping the cash as a deposit is a genuine trade-off: deposit size drives your loan-to-value ratio, and lenders' treatment varies. Before deciding anything, know your own numbers: your payoff date under compulsory repayments alone (our HECS repayment calculator projects it), and the timing rules in our voluntary repayments guide if you do pay early. What's right for your loan is a question for your lender or broker: general information here, not financial or credit advice.
