HECS, or HECS-HELP, is a type of study and training support loan offered by the Australian government. You may be eligible for a HECS-HELP loan if you attend an approved higher education provider – that is, a provider eligible to offer Commonwealth Supported Places (CSPs) and HELP loans… like most Universities. The government then pays part of your fees in a CSP, and the remaining amount not covered by the subsidy, called the student contribution amount, is paid by the government through a HECS-HELP loan. You then owe this amount back to the government.
The bad news? With most loans, we end up paying back more than what we originally received.
That also applies to HECS-HELP. While it does not incur interest, the amount increases through indexation. Indexation is an adjustment applied to your debt on 1 June every year. This ensures that the amount you borrowed today is worth the same in the future – accounting for the rising cost of providing education over time.
The good news? We actually have four points:

The great thing about HECS-HELP is that you don’t have to start paying it back straight away, and not out of your money physically in the bank. It all gets sorted out as part of your tax return.
Repayments are income-based, which means compulsory repayment is required only when your income reaches a certain amount. In the 2025–26 income year, the threshold is $67,000. You can check thresholds here.
Income includes:
Each year, the ATO checks your income when you lodge your tax return and calculates how much you need to repay. If your income is below the threshold, you won’t have to make any compulsory repayments.
If you are an employee, you need to notify your employer about your HECS loan (tick the box on the tax declaration form) and authorize them to withhold amounts (PAYG deduction) from your regular pay to cover your compulsory repayment. Once you reach the income threshold, your employer automatically adjusts your PAYG withholding to include your compulsory HECS repayment. This means it’s included in the amount your employer withholds from your gross pay. You get sent a little less to work with every week, but the ATO collects the HECS bit directly from your employer.
Even if your income hasn’t reached the repayment threshold yet, you can choose to make voluntary repayments on your HECS-HELP loan at any time. Doing this before 1 June can reduce the balance used for the next indexation period. Voluntary payments are applied in addition to your compulsory repayments – they are separate payment transactions, but both reduce your HECS balance.
You can make voluntary repayments online through the ATO, or by setting up a regular payment if you prefer to spread it out. Even a small voluntary repayment each month can help reduce your HECS balance. Think of it as a way to get ahead on your loan while keeping your repayments manageable.
Tip: Think of PAYG withholding as a way to automatically save for your HECS repayment throughout the year. If you have multiple jobs or your income isn’t fully taxed through PAYG, you might still need to set aside extra money for your repayments. Think of it as part of your overall tax and budget planning – it keeps things stress-free when tax time rolls around.
If you move overseas or live outside Australia, here’s what you need to know:
Tip: Keep your contact details and overseas address updated with the ATO. This helps avoid missed notices or repayment calculations while you’re abroad. It’s also a good idea to plan ahead for currency conversions so your repayment is correct when it reaches the ATO.
While compulsory repayments are required, there are ways to give yourself a break if you’re going through challenging times – think of it as a temporary safety net. The ATO allows you to defer or amend loan repayments in certain circumstances.
You can defer your loan repayments for the following reasons:
To support your claim to defer your loan repayment, you need to submit a detailed statement of your household cash flow to the ATO. The ATO may also require you to provide further evidence to support your income and expenses, such as a copy of your recent payslip.

Even though HECS-HELP repayments are income-based, they affect your tax planning – especially if you have multiple income streams, are a sole trader, or don’t have enough tax withheld through PAYG. But don’t worry – avoiding surprises at tax time is easy with these four steps:
Example:
HECS-HELP might seem a little overwhelming at first, but once you understand how repayments work, how PAYG withholding helps, and how voluntary payments can give you a head start, it’s really just part of your overall tax and budgeting plan.
By keeping track of your income, expenses, and repayments – and staying aware of thresholds and options like deferrals – you can manage your loan with confidence and avoid last-minute surprises. Think of it as a mini tax plan: being informed, organized, and proactive will make HECS repayments feel a lot less stressful and help you keep your finances on track. Plus, with a few smart moves like voluntary payments, you can say goodbye to HECS loans faster and enjoy that extra peace of mind knowing you’re ahead of the game.
