HECS-HELP Debt and Home Loan Borrowing Capacity in Australia 2026: A Mortgage Broker Guide

For millions of Australians who studied at university or completed vocational training, HECS-HELP debt is a familiar financial reality. What many borrowers do not fully appreciate is how this debt interacts with their ability to obtain a home loan. In 2026, following a series of significant policy changes — including a 20% debt reduction, a new marginal repayment system, and updated APRA guidance — the rules around HECS-HELP and mortgage lending have shifted in ways that can meaningfully affect your borrowing capacity. Understanding these changes, and working with an experienced mortgage broker, can make a real difference to your home ownership journey.

How HECS-HELP Debt Affects Your Home Loan Application

HECS-HELP debt does not appear on your credit report and does not directly affect your credit score. However, it does affect your home loan application in a more indirect but equally important way: through the compulsory repayment obligation that reduces your disposable income.

When a lender assesses your ability to service a mortgage, they calculate your net income after all regular financial commitments. Because HECS-HELP repayments are compulsory once your income exceeds the repayment threshold, lenders treat them as a recurring expense — similar to a car loan or credit card repayment — that reduces the amount you can afford to borrow.

A commonly used rule of thumb among mortgage brokers is that every $1 of annual HECS repayment reduces your borrowing capacity by approximately $10. For a borrower with a $5,000 annual HECS repayment, this could translate to a reduction in borrowing capacity of around $50,000 — a significant amount in the current property market.

Key Policy Changes in 2025 and 2026

Several important changes have reshaped how HECS-HELP debt interacts with home loan applications. Borrowers and their mortgage brokers need to understand each of these changes to accurately assess their position.

The 20% Debt Reduction (June 2025)

In June 2025, the Australian Government applied an automatic 20% reduction to all outstanding HELP balances. This was a one-off measure designed to address the cumulative impact of CPI indexation on student debt. While this reduction lowered the total balance owed, it does not automatically increase borrowing capacity unless the reduced balance is small enough to be cleared within approximately 12 months — which triggers a separate lender concession discussed below.

The New Marginal Repayment System (July 2025)

From 1 July 2025, the government replaced the previous flat-percentage repayment method with a new marginal repayment system. Under the 2026-27 rules, no compulsory repayments are required on income up to $69,528. Above that threshold, repayments are calculated at 15 cents for every dollar earned above the threshold, rather than applying a flat percentage to total income.

This change generally results in lower compulsory repayments for many borrowers, particularly those earning in the lower-to-middle income ranges. Lower repayments mean less of a drag on disposable income, which can modestly improve borrowing capacity.

APRA Guidance on the 12-Month Exclusion Rule

Effective September 2025, APRA provided updated guidance allowing lenders to exclude HECS-HELP repayments from their serviceability assessments if the outstanding debt is expected to be fully repaid within approximately 12 months. This is a significant concession for borrowers with small remaining balances.

If your HECS balance is close to being cleared, making a voluntary lump-sum repayment to bring it within the 12-month window could meaningfully increase your borrowing capacity. A mortgage broker can model this scenario for you and advise whether the trade-off — using savings to pay down HECS versus preserving those funds for a deposit or offset account — makes financial sense in your specific situation.

HECS-HELP Excluded from DTI Reporting

In a further positive development, HECS-HELP debt is now excluded from APRA''s Debt-to-Income (DTI) reporting requirements. This means that even under the DTI cap framework introduced in February 2026 — which limits high-DTI lending to 20% of new mortgage volumes — HECS debt does not count toward the DTI calculation. This is a meaningful distinction for borrowers who might otherwise be close to the DTI threshold.

Strategies to Maximise Your Borrowing Capacity

Understanding the rules is one thing; applying them strategically is another. A skilled mortgage broker can help you implement the following approaches to maximise your borrowing capacity when HECS-HELP debt is a factor.

• Assess the 12-month payoff window — If your remaining HECS balance is small, calculate whether a voluntary repayment would bring it within the 12-month exclusion threshold. The borrowing capacity gain may significantly outweigh the cost of the repayment.
• Prioritise other debt reduction first — Credit card limits (even with a $0 balance) and personal loans are often treated more harshly by lenders than HECS debt. Reducing credit card limits or closing unused accounts can have a greater positive impact on borrowing capacity than paying down HECS.
• Choose the right lender — Lender policies on HECS treatment vary. Some lenders apply the 12-month exclusion rule more generously than others, and some are more flexible in how they assess HECS repayments for borrowers with variable income. A mortgage broker with access to a broad panel of lenders can identify the most favourable policy for your circumstances.
• Time your application strategically — If you are close to paying off your HECS debt, it may be worth waiting until the balance is cleared before applying for a home loan. The improvement in borrowing capacity could justify a short delay.
• Optimise your income documentation — For borrowers with variable income, bonuses, or multiple income streams, how income is documented and presented to lenders can affect the HECS repayment calculation. A mortgage broker can advise on the most favourable approach.

Common Misconceptions About HECS and Home Loans

Several persistent myths about HECS-HELP debt and home loans can lead borrowers to make suboptimal decisions. It is worth addressing the most common ones directly.

• Myth: HECS debt appears on your credit report — It does not. HECS-HELP is not a commercial debt and is not reported to credit bureaus. It will not affect your credit score.
• Myth: You should always pay off HECS before buying a home — This is not necessarily true. HECS is indexed to CPI rather than bearing a commercial interest rate, making it one of the cheapest forms of debt available. For most borrowers, preserving savings for a deposit or offset account is more financially efficient than paying down HECS — unless the 12-month exclusion rule applies.
• Myth: The 20% debt reduction automatically increased my borrowing capacity — Not necessarily. The reduction only improves borrowing capacity if it brings the balance within the 12-month exclusion window. Otherwise, the compulsory repayment amount — which is what lenders focus on — may not have changed significantly.
• Myth: All lenders treat HECS debt the same way — They do not. Lender policies vary considerably, and working with a mortgage broker who understands these differences can make a material difference to your outcome.

Australian Regulatory Context

Mortgage brokers in Australia are regulated by ASIC under the National Consumer Credit Protection Act 2009 and are subject to a best interests duty when providing credit assistance. This means a broker must act in your best interests, not the lender''s, when recommending a home loan product.

The Australian Financial Complaints Authority (AFCA) provides an external dispute resolution service for consumers who have complaints about mortgage brokers or lenders. If you believe a broker has not acted in your best interests, you can lodge a complaint with AFCA at no cost.

APRA''s macroprudential framework, including the 3 percentage point serviceability buffer and the DTI cap introduced in February 2026, continues to shape the lending environment. While HECS debt is excluded from the DTI calculation, the serviceability buffer still applies to all new lending, meaning lenders must assess whether you can afford repayments at a rate 3 percentage points above the loan''s actual rate.

The Australian Competition and Consumer Commission (ACCC) has also been active in monitoring mortgage market competition, and the Consumer Data Right (CDR) framework is progressively expanding to non-bank lenders, which may open up additional options for borrowers with HECS debt who are seeking more flexible lending policies.

Questions to Ask Your Mortgage Broker

When meeting with a mortgage broker to discuss a home loan application where HECS-HELP debt is a factor, these questions will help you get the most useful advice.

• How does my current HECS balance and annual repayment affect my borrowing capacity with different lenders?
• Would making a voluntary HECS repayment to reach the 12-month exclusion threshold improve my borrowing capacity enough to justify the cost?
• Which lenders on your panel have the most favourable policies for borrowers with HECS debt?
• How does my HECS repayment interact with the APRA serviceability buffer in your assessment?
• Are there other debts or financial commitments I should address before applying to maximise my borrowing capacity?
• How are you remunerated, and does this affect which lenders you recommend?
