HECS repayment on $200,000

How $200,000 becomes $20,000.00

Worked in full: $200,000 × 10% = $20,000.00. That is the entire calculation for this band — no threshold subtracted first, no fixed amount added after. Every dollar of $200,000 is taxed at the same 10% rate for this purpose, including the first one.

Under the 2025-26 rules the repayment on $200,000 would have been identical: $20,000.00. The threshold moved between the two years but not by enough to change this particular figure.

Here is what a raise actually looks like on $200,000: the next dollar loses 45c to income tax, 2c to the Medicare levy, and 10c to HECS — 43.0c makes it to your bank account. That is the marginal rate on the next dollar, not the average rate on $200,000 as a whole; every dollar already earned kept more, because the earlier brackets charge less.

A $5,000 raise on $200,000 does not arrive whole. Income tax takes $2,250.00 of it, the Medicare levy $100.00, and HECS $500.00 more — $2,150.00 (43%) actually lands in the bank.

The 10% band at $200,000

The $20,000.00 at $200,000 is not marginal. The top band charges 10% of your whole repayment income, not of the amount above $186,051. That is why a $10,000 raise from $200,000 adds exactly $1,000.00 to the repayment, the full 10% of the extra, with no fixed component to amortise.

If you hold more than one study loan, the $20,000.00 is not split across them evenly. The ATO applies compulsory repayments in a set order, HELP debts (including HECS-HELP, FEE-HELP and VET Student Loans) are cleared before an SFSS debt. One repayment amount is calculated from your $200,000, then allocated down that order.

An employer withholds extra tax against a HELP debt automatically, but someone earning $200,000 as a sole trader has no employer doing that. The $20,000.00 compulsory repayment still applies, worked out the same way, from the same repayment income, but it is paid through PAYG instalments during the year or settled in full when the tax return is lodged, rather than skimmed off a regular pay run.

The $69,528 figure that decides whether $200,000 owes anything at all is not fixed. Repayment thresholds move on 1 July each year, separately from the 1 June balance indexation covered elsewhere on this page, a different mechanism adjusting a different number. A salary that sits just above this year's threshold can sit just under next year's if the threshold rises faster than the income does.

There is no minimum time a HELP debt has to run, and no penalty for clearing it faster than the compulsory schedule set by $20,000.00 a year would. Making the debt disappear only ever happens by paying the balance down to zero, through compulsory repayments, voluntary ones, or both, waiting it out is not an option, since indexation keeps the remaining balance moving each 1 June.

Common questions

Why does the effective rate equal the marginal rate here?

Because the top band has no fixed component and no threshold offset. At $200,000 the 10% applies to every dollar, so the effective rate (10.0%) matches the marginal rate. Below $186,051 the effective rate is always lower because fixed amounts are spread across the whole income.

What if I have more than one study loan?

One repayment of $20,000.00 is calculated from your income, then applied in the ATO's set order, HELP debts before an SFSS debt.

I'm self-employed. How do I actually pay this?

There is no employer withholding to cover it, so the $20,000.00 is paid through PAYG instalments during the year or settled in full when you lodge, the $200,000 figure it is calculated from works the same way either way.

Does the repayment threshold stay the same every year?

No, it moves on 1 July each year, separately from the balance indexation on 1 June. This page shows the $69,528 threshold for the current year; next year's figure will differ.

Can I just wait for this debt to go away?

No. There is no time limit that clears a HELP debt on its own, it only reduces through repayment, compulsory ($20,000.00 a year here) or voluntary, while indexation keeps adjusting whatever balance remains each 1 June.
