HECS repayment on $165,000

How $165,000 becomes $15,026.11

Worked in full: $165,000 is past the second threshold, so the repayment has two parts. The fixed part is $9,028 — what everyone in this band owes before their own income is even considered. The variable part is 17c on the $35,283 above $129,717: $35,283 × 0.17 = $5,998.11. Add the two: $9,028 + $5,998.11 = $15,026.11.

Under the 2025-26 rules — a $67,000 threshold instead of 2026-27's $69,528 — the repayment on $165,000 would have been $15,500.00, $473.89 less than this year's $15,026.11.

Here is what a raise actually looks like on $165,000: the next dollar loses 37c to income tax, 2c to the Medicare levy, and 17c to HECS — 44.0c makes it to your bank account. That is the marginal rate on the next dollar, not the average rate on $165,000 as a whole; every dollar already earned kept more, because the earlier brackets charge less.

A $5,000 raise on $165,000 does not arrive whole. Income tax takes $1,850.00 of it, the Medicare levy $100.00, and HECS $850.00 more — $2,200.00 (44%) actually lands in the bank.

Past the second threshold at $165,000

$165,000 is above $129,717, so the repayment is built in two parts: a fixed $9,028 covering everything up to that point, plus 17 cents on each of the $35,283 above it, $15,026.11 in total, an effective rate of 9.1%. This is the band where the marginal and effective rates pull furthest apart. Above $186,051, still $21,051 away, the schedule stops being marginal altogether.

Two jobs adding up to $165,000 behave differently from one job paying $165,000. Each employer withholds against its own pay scale as though it were your only income, so neither sees the combined figure and both under-withhold. The compulsory repayment is calculated once, on the combined $165,000, and the shortfall shows up as a bill at assessment.

What the $15,026.11 does not depend on is worth stating plainly. It is not means-tested against savings or assets, it is not reduced by dependants, and it does not change if you are paying a mortgage. Hardship relief exists but is a separate deferral application to the ATO, not an adjustment to the $165,000 calculation itself.

Since the November 2024 changes, indexation is the lower of the Consumer Price Index (CPI) or the Wage Price Index (WPI), so a HELP debt can no longer grow faster than wages. The 2.8% figure for 2026 is what that cap produced. The $15,026.11 on this page is unaffected, indexation adjusts the balance, not the compulsory repayment, which is worked out from your income alone.

An employer withholds extra tax against a HELP debt automatically, but someone earning $165,000 as a sole trader has no employer doing that. The $15,026.11 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.

Common questions

How much HECS do I pay on $165,000?

On a repayment income of $165,000 in 2026-27 the compulsory repayment is $15,026.11, $9,028 plus 17 cents for each dollar over $129,717. That is about $1,252.18 a month.

I have two jobs. Is the calculation different?

The calculation uses your combined repayment income, so two jobs totalling $165,000 give the same $15,026.11. Each employer withholds as if it were your only job, so expect a shortfall at assessment rather than a refund.

Is this reduced if I have dependants or a mortgage?

No. The $15,026.11 is calculated from repayment income only, it is not means-tested against assets and is not adjusted for dependants. Deferral on hardship grounds is a separate application to the ATO.

How is the indexation rate worked out now?

Since November 2024 it is the lower of CPI or WPI, so the debt cannot grow faster than wages. The 2.8% for 2026 is what that cap produced. It adjusts the balance, not the compulsory repayment.

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

There is no employer withholding to cover it, so the $15,026.11 is paid through PAYG instalments during the year or settled in full when you lodge, the $165,000 figure it is calculated from works the same way either way.
