How to Pay Your HELP Debt: BPAY, Card, myGov

To pay your HELP debt voluntarily, get your Payment Reference Number (PRN) from ATO online services through myGov or the ATO app, then pay by BPAY using biller code 75556, by card, or by direct credit. To beat 1 June indexation, pay several business days before the end of May.

Knowing how to pay HELP debt is mostly about three details: the right PRN, the right payment channel and the right timing. Compulsory repayments already come out through your tax return and the Australian Taxation Office (ATO) withholding system; this guide covers the voluntary payments you make yourself, whether a lump sum from a tax refund or a regular top-up. It walks through BPAY, card and myGov step by step, then shows the processing times that decide whether your payment beats indexation.

Before you pay: find your HELP debt balance and PRN

Every voluntary payment needs a Payment Reference Number. The PRN tells the ATO which account to credit. Use the wrong one and your money can land against an income tax account instead of your study loan, which then needs a phone call to move.

1. Sign in to myGov and open the linked ATO online services, or open the ATO app.
2. Go to the tax accounts area and select your study and training loan account (it may be labelled HELP or study loans).
3. Check the balance. It already reflects the one-off 20% reduction applied to balances as at 1 June 2025, and the most recent 1 June indexation.
4. Choose the option to make a payment and note the PRN shown for that account. Save it in your banking app so you can reuse it.

Your balance may lag a few weeks behind recent tax lodgments or compulsory repayments. If you are close to paying the debt off completely, wait for the latest assessment to process so you do not overpay. To model the effect of a lump sum before you commit, use our voluntary repayment calculator, which shows how much indexation a payment avoids and how many years it takes off the loan.

How to pay HELP debt: the payment methods compared

The ATO accepts voluntary study loan payments through several channels. They differ mainly in cost and in how quickly the payment is credited. Official details are on the ATO's Pay with BPAY page and its related how-to-pay pages.

Processing times are guides, not guarantees. The ATO credits the payment on the day it receives the funds, not the day you press "pay", so a Friday-night BPAY might not arrive until the following week.

Paying by BPAY step by step

BPAY is the most common way to make a HELP debt voluntary repayment because it is free and you can set it up once and reuse it.

1. Log in to your internet or mobile banking and choose BPAY.
2. Add a new biller with biller code 75556. Your bank should show the biller name as the Australian Taxation Office.
3. Enter your study loan PRN in the reference field exactly as shown, with no spaces.
4. Enter the amount and the payment date. Avoid scheduling for a weekend or public holiday.
5. Save the receipt number. If the payment does not appear on your ATO account within about a week, the receipt is what the ATO will ask for.

Setting up regular payments

Most banks let you make a BPAY payment recurring. A fixed monthly amount is a practical way to chip away at the balance between tax returns, especially if your income is under the $69,528 compulsory threshold for 2026-27 and nothing is being withheld from your pay. Check your account a few days after the first scheduled payment to confirm it is landing on the study loan account.

Paying by card or through myGov

Card payments go through the ATO's third-party card payment service rather than directly to the ATO, which is why a fee applies. Visa, Mastercard and American Express are generally accepted; check the current fee percentage and card list on the ATO's how-to-pay pages before you pay, because providers and fees can change.

• Online: start from ATO online services in myGov, choose to make a payment against the study loan account, and follow the card option.
• By phone: the card payment service also offers phone payment; have your PRN ready.
• Fee maths: on a $5,000 payment, even a small percentage fee costs real money. If indexation for the year is expected to be modest, paying the fee to save a few days may not be worth it. Use BPAY early instead.

Timing your payment before 1 June indexation

Indexation is applied on 1 June to the balance that has been outstanding for more than 11 months. A voluntary payment only reduces that indexed balance if the ATO has received it before 1 June. For the 2027 cycle, work backwards from the calendar:

These are practical buffers, not ATO rules. The ATO usually publishes a reminder each May, and past years have suggested paying by around the last week of May. Check that reminder each year.

How much indexation you actually save

The saving is roughly the amount you pay multiplied by that year's indexation rate. A $5,000 payment made before 1 June when indexation is about 3% avoids around $150 of indexation that year, and slightly more over later years because the indexed amount would itself be indexed again. The saving is real but modest, which is why paying HELP debt early is a personal choice rather than an obvious win.

What happens after you pay

• Balance update: the payment normally shows on your study loan account within a few business days of the ATO receiving it.
• Compulsory repayments continue: a voluntary payment lowers the balance but does not cancel that year's compulsory repayment if your repayment income is above the threshold and a debt still remains.
• Paying it off completely: once the balance is nil, update your details with every employer (answer "no" to the study loan question on a withholding declaration) so they stop withholding for HECS.
• Refunds: voluntary payments are generally not refundable unless you have paid more than you owe. If you overpay, the excess is usually applied to other ATO debts first, then refunded.

Common mistakes when paying HELP debt

• Using an old or wrong PRN. Always copy the PRN from the study loan account screen rather than from an old notice.
• Paying on 31 May. The ATO needs the money by 1 June, not your bank's confirmation.
• Paying off more than the final balance. Wait for your latest compulsory repayment to post if you are close to zero.
• Forgetting the employer update. Withholding continues until you tell your employer the loan is repaid, and you then wait for a refund at tax time.
• Paying HELP ahead of costly debt. Credit card or personal loan interest usually costs far more than indexation. Many people clear those first, then turn to HELP.

Special situations when you pay HECS debt

Living overseas

If you move overseas for 183 days or more in a 12-month period, you must update your contact details with the ATO within 7 days of leaving and lodge an overseas income assessment (or a non-lodgment advice) each year. Any overseas-based repayment raised against your worldwide income can be paid with the same BPAY biller code 75556 from an Australian bank account, or by card from abroad. International transfers work too, but allow extra days and watch for bank fees that shave the amount received.

Paying a lump sum from a tax refund

A tax refund arrives in your bank account, not against your HELP balance. If you want it to reduce the debt, you have to pay it back in as a voluntary repayment using your PRN. Many people do this in July or August, which gives the payment almost a full year to reduce the next 1 June indexation.

Paying on someone else's behalf

Parents or partners can pay a HELP debt for you with BPAY, as long as they use your PRN. The payment counts as yours. Make sure the payer keeps the receipt and that you check your account afterwards, because a mistyped PRN can send the money to a stranger's account and take weeks to trace.

Worked example: a $3,000 payment in May

At an indexation rate of about 3%, the payment saves roughly $90 of indexation in its first year. Dates and rates in this example are illustrative; use the calculator with your real balance and the latest rate before you pay HECS debt voluntarily.
