HECS debt holding you back? What can you still borrow?

A HECS debt reduces what you can borrow by its compulsory repayment, not by the balance.

Read more

Lenders deduct the yearly HELP repayment from your income, which under the ATO’s current rates is nothing below about $69,500 and 15 per cent of income above that threshold, rising at higher incomes. HECS repayments have worked this way since 1 July 2025, when they moved from a share of your whole income to a share of the income above the threshold, which lowered most repayments and lifted borrowing power.

A $30,000 debt and a $60,000 debt on the same income cost the same borrowing power.

Charles Touma from Links Property Finance was a great help with buying my first home. I had plenty of questions and he took the time to explain things clearly without making me feel rushed. He kept me updated throughout and made the process much less stressful. Really appreciated his patience and would happily recommend him to other first home buyers.

The repayment matters, the balance mostly doesn't

  • The repayment, not the balance, is the part that surprises people.Two buyers on the same income, one with a $15,000 HELP debt and one with $60,000, will usually be assessed almost identically. Neither balance is treated as a debt to be cleared. What the lender cares about is the compulsory repayment that comes out of your pay each year, because that is money you cannot put toward a mortgage.
  • Your compulsory repayment is worked out as a percentage of your income once you pass the repayment threshold, and it rises as your income rises.So the person earning more pays more, regardless of what they owe. A large balance means you will be making that repayment for longer.

How much borrowing power does it cost?

  • Roughly speaking, every dollar of annual compulsory repayment reduces your assessed surplus by a dollar, and lenders convert surplus into loan size at their assessment rate rather than the rate you would pay.That assessment rate is typically around three percentage points above the real rate.
  • The practical effect is that a compulsory repayment in the low thousands per year commonly costs somewhere in the tens of thousands of borrowing capacity.It is meaningful, but it is rarely the difference between buying and not buying. Estimate your borrowing power.

Where does lender policy differ?

Lender policy on HECS is the part worth having someone check, because the spread between lenders on the same application can be material.

  • Some lenders will disregard a HELP debt entirely where the remaining balance is small enough that it will clear within a short window, commonly around twelve months. If you are close to the end of your debt, that single policy difference can be worth more than any rate negotiation.
  • Others apply the repayment as a fixed ongoing commitment for the full loan term, which is the most conservative reading and produces the lowest number. Between those two positions sit most lenders, and which one you approach changes your maximum.
  • Policy in this area also shifts as the rules change. It is one of the clearer cases where comparing a panel beats guessing.

Should you pay it off before applying?

Usually not, and the reasoning is worth understanding rather than taking on trust.

  • Paying down the balance does not reduce your compulsory repayment, because that repayment is calculated from your income. Unless the payment clears the debt entirely, or brings it low enough to fall inside a lender's disregard policy, you have spent deposit money without improving your borrowing power at all.
  • And deposit money is doing more work where it is. A dollar of deposit reduces your loan, reduces your loan-to-value ratio, and may reduce or remove lenders mortgage insurance. A dollar off a HELP balance usually does none of those things.
  • The exception is a small remaining balance. Clearing $3,000 to remove a repayment for good can be worth it. Paying $20,000 off a $50,000 debt generally is not.

Things worth knowing before you apply

Getting the numbers right

Repayment thresholds and rates are set by the Australian Government and change most years, and the system was restructured in recent years to use marginal rates rather than a single percentage of total income.

Any figure you find online is only as current as the page it sits on.

Rather than reproduce numbers that date, we check your actual position against the current rules at the time you apply. The authoritative sources are the Australian Taxation Office and Study Assist.

How Links helps

Work out what your compulsory repayment is at your income, and what it costs you in borrowing capacity in real terms rather than as a vague worry.

Then match you to lenders whose HELP policy suits your position. If your balance is close to clearing, that means finding the lenders who will disregard it. If it is substantial, it means avoiding the ones that treat it most harshly.

Common questions about HECS and home loans

Does HECS affect how much I can borrow?

Yes, but through your compulsory repayment rather than your balance. The repayment reduces the income a lender has available to service a mortgage, and because lenders assess at a rate above the actual rate, that reduction is amplified when converted into a loan amount.

Should I pay off my HECS before applying for a home loan?

Usually not. Paying part of the balance does not reduce your compulsory repayment, because that is calculated from your income, so you would spend deposit money without improving your borrowing power.

Does a HECS debt show on my credit file?

No. HELP debts are administered through the tax system, not as consumer credit, so they do not appear on your credit report and do not affect your credit score.

Do all lenders treat HECS the same way?

No, and the difference can be worth a lot. Some lenders will disregard the debt where the remaining balance would clear within roughly a year. Others apply the repayment as an ongoing commitment for the whole loan term. Most sit between the two.

Can I get a first home buyer scheme with a HECS debt?

Yes. Government scheme eligibility does not consider student debt. It turns on things like citizenship or residency, whether you have previously owned property, the price of what you are buying and your intention to live in it.

A HECS debt is only one of the things first home buyers ask about, and our first home buyer FAQ answers plenty of the others.
