HECS Debt: Should You Pay It Off Early or Let It Ride?

HECS debt is one of those financial annoyances that is easy to ignore until you start earning more, see the balance creep up on 1 June, or try to buy a home and discover the lender definitely has an opinion about it.

The short answer is this: most people do not need to rush to pay off HECS early. But there are a few situations where smashing it makes sense, especially if you are close to buying property or the money would otherwise just sit around doing bugger all.

How HECS works in 2026

HECS-HELP is not like a normal loan. There is no monthly bill, no minimum direct debit, and no banker calling you at dinner. Repayments are income-contingent, which is a fancy way of saying you only start making compulsory repayments once your repayment income gets high enough.

The big change is that the rules are now more forgiving than the old system. The ATO says that from the 2025-26 income year, compulsory repayments moved to a marginal repayment system. For the current 2026-27 year:

• no compulsory repayment applies up to $69,528
• from $69,529 to $129,717, you pay 15 cents for each $1 above $69,528
• from $129,718 to $186,050, you pay $9,028 plus 17 cents for each $1 above $129,717
• from $186,051 and over, you pay 10% of total repayment income

That is meaningfully better than the old all-or-nothing percentage system. The first year of the new rules was 2025-26, and the ATO's own example shows someone on $80,000 paid $1,950 for that year, instead of $2,800 under the previous rules. That is not pocket change. That is a few utility bills and at least one emotionally unnecessary Bunnings trip.

Why old HECS advice is stale now

A lot of the internet is still giving HECS advice as if it is 2023. That is a problem because the rules changed.

Two changes matter most:

1. Compulsory repayments are now marginal, which reduces the annual hit for many people.
2. Indexation is based on the lower of CPI or WPI, not just CPI. StudyAssist says the 1 June indexation rate was 4.0% in 2024, 3.2% in 2025, and 2.8% in 2026.

The ATO also says it processed the one-off 20% debt reduction for eligible study and training support debts that existed on 1 June 2025. So if your brain is still stuck on the huge 2023 indexation shock, fair enough, but the current settings are not quite the same beast.

The case for paying it off early

1. You are buying a home soon

This is the big one. Lenders usually treat your compulsory HELP repayment as an ongoing commitment when they assess serviceability. That means HECS can reduce your borrowing capacity, even if it does not feel like a normal debt to you.

If paying off your remaining balance gets you over the line for the place you actually want, or helps keep your budget more comfortable, that can be a very rational use of cash. Not glamorous, but rational. SmartKoala likes rational.

2. Your balance is small and annoying

If you have, say, $3,000 to $8,000 left and decent savings, clearing it can simplify life. You stop thinking about annual indexation, stop seeing it on the ATO portal, and stop carrying it into home loan applications.

3. The alternative is just idle cash

If the money is otherwise going to sit in a low-interest account earning less than current HELP indexation, a voluntary repayment can be the cleaner move. At the current 2.8% rate, paying down $10,000 of HELP saves roughly $280 of next year's indexation if that debt would still be outstanding on the next 1 June.

That is not life-changing. But it is a guaranteed outcome, and sometimes guaranteed beats theoretical.

The case for letting it ride

1. It is still one of the gentler debts you can have

HECS is income-contingent. If your income drops below the threshold, compulsory repayments stop. A mortgage does not care. A credit card definitely does not care. That flexibility has real value.

2. Your cash may have a better job to do

Emergency funds, high-interest debt, deposit savings, and concessional super contributions can all beat early HELP repayment depending on your goals. If you have no safety buffer, paying off HECS early can be a weirdly confident move right before life decides to get expensive.

3. Long-term investing can still win mathematically

Let us say you have $10,000 spare.

• If you put it toward HELP and the current indexation rate stayed at 2.8%, the immediate one-year saving is roughly $280.
• If you invested the same $10,000 and earned an average 6% a year for 10 years, it could grow to about $17,900 before tax and fees.

That does not mean investing always wins. Returns are not guaranteed, and markets can be rude for years at a time. But it does show why plenty of people choose to let HELP repay itself through the tax system while they build wealth elsewhere.

So, when does paying HECS early actually make sense?

For most Australians, it is usually one of these three situations:

• you are about to apply for a mortgage and every bit of serviceability matters
• you have a small remaining balance and want to clean it up
• your cash has no better use than avoiding indexation

If none of those apply, letting it ride is often perfectly reasonable.

A simple decision framework

If you are stuck, use this extremely unsexy but useful order:

1. Build an emergency fund first.
2. Pay off any ugly high-interest debt first.
3. If you are buying soon, test how much HECS is hurting your borrowing capacity.
4. If you are not buying soon, compare HELP indexation with the likely return on your next best option.
5. If the numbers are close, choose the option that helps you sleep better.

Personal finance is math, but it is also behaviour. The best move on paper is useless if you will not stick to it.

The home buyer exception is real

This bit deserves its own section because it catches people out. A lot of good general HECS advice says not to rush voluntary repayments. That is often true. But when you are trying to buy property, the game changes.

If clearing HELP means:

• you qualify for the loan size you need
• you avoid a tighter monthly budget than you want
• you can buy sooner rather than waiting another year

...then the "never pay HECS early" crowd can politely take a seat.

This is especially worth checking if you are already comparing deposit size, repayments and lender policy. Run the numbers with your Borrowing Capacity Calculator, then sanity-check the repayment impact with the HECS Repayment Calculator.

The bottom line

In 2026, HECS is still not the financial fire you need to sprint at with a bucket. The newer repayment rules are kinder, indexation is no longer CPI-only, and for many people the smarter move is to keep cash flexible or invest for the long term.

But if you are close to buying property, carrying only a small remaining balance, or leaving cash parked uselessly, paying HECS early can absolutely be the right call.

Just do not rely on old Reddit lore or one mate who says HELP is always "good debt". Sometimes it is. Sometimes it is just a mildly annoying line item blocking your mortgage application.
