HECS vs Home Deposit — Where Should Your Money Go First?

By , Melbourne Read: 3 min Checked against: ATO, Study Assist

Australian graduates face this question constantly, and lender serviceability rules make the answer counter-intuitive. Here's the current framework for 2026.

The short answer

Save for the home deposit first — unless your HECS balance is small enough ($5,000 or less) that clearing it entirely would unlock meaningful borrowing power. For any HECS balance above that, the deposit has higher leverage.

Why the deposit wins in most cases

Home lenders care about two things: your deposit size (loan-to-value ratio) and your serviceability (ability to repay the loan). Reducing HECS only helps serviceability — and only if the balance is clearable.

  • Partial HECS payments do not change your compulsory repayment rate (it's income-based, not balance-based), so they don't improve serviceability unless they clear the balance.
  • Every extra dollar of deposit directly reduces your LVR, reduces your LMI premium if you're below 20%, and can qualify you for better loan products.
  • The First Home Super Saver Scheme (FHSS) lets you put voluntary super contributions toward a deposit and withdraw them at concessional tax rates — effectively a 15–30% tax benefit depending on your bracket.

When to pay HECS first

  1. HECS balance under $5,000. Clearing it entirely removes the HECS line from lender serviceability and typically unlocks $50,000+ of borrowing power — more than the cash cost of the repayment.
  2. You're already at your target deposit. If you've got 20%+ saved and lender serviceability is the binding constraint, aggressive HECS repayment is the next lever.
  3. You've maxed the FHSS cap. The FHSS cap is $15,000 per year and $50,000 total. Beyond that, HECS repayment may beat taxable investment on an after-tax basis.

Worked example — $45,000 savings, $25,000 HECS, $85,000 income

Option A: Pay $25,000 HECS in full. Deposit reduces to $20,000. HECS serviceability impact removed ($4,500/year less fixed expense) — unlocks roughly $45,000 – $67,500 of borrowing power. Net effect on maximum purchase price: +$45,000 – $67,500 borrowing, –$25,000 deposit = +$20,000 to +$42,500 purchase price.

Option B: Keep $45,000 deposit. HECS stays. Same borrowing power as before, same serviceability drag. No change.

Option C: Use FHSS for additional deposit boost. Keep HECS. Save another $30,000 into FHSS over 2 years, boosting deposit to $75,000 with concessional tax treatment.

Option A typically wins if borrowing capacity (not deposit size) is your binding constraint. Option C wins if your LVR is the constraint.

Tips & Tricks

Pay off HECS faster — actionable tactics

Hand-picked strategies Australian graduates actually use. Each one can be implemented this financial year — no gimmicks, no affiliate links.

  1. 01

    Chuck a voluntary payment in before 1 June

    This one's the big one. Indexation hits on 1 June, and it only applies to whatever is sitting on your balance that day. If you transfer, say, $5,000 in the last week of May, indexation at 3.4% never touches that $5k — so you save around $170 in one go. I did this three years running and it's the single easiest win.

    Do this: Grab your PRN from myGov → ATO → Loan Accounts, then BPAY it. Do it 5 business days before 1 June — banks can be slow.

  2. 02

    Tick the HECS box on your TFN declaration

    Your employer only withholds extra tax for HECS if you tell them you have a debt. I've met grads who got smacked with a $9,000 bill at tax time because they never ticked the box — their payroll had no idea. Getting it withheld from each pay is way less painful than one brutal June invoice.

    Do this: Email payroll and say: "Please update my TFN declaration to indicate I have a HELP debt." Sorted next pay cycle.

  3. 03

    Add your fringe benefits and super to your income estimate

    The ATO uses "repayment income" — not just your salary. It adds back reportable fringe benefits (novated lease is the big one), reportable employer super, net investment losses, and exempt foreign income. A mate of mine on a $95k salary with a $12k novated lease tipped into the 15% bracket and was furious when the letter arrived.

    Do this: Check your last payment summary, grab the RFBA number, and add it to your gross before using the calculator.

  4. 04

    Don't part-pay your HECS before applying for a home loan

    This catches loads of people out. Banks only drop HECS from their serviceability calc when your balance is exactly zero. If you have $25k and pay $20k of it, the bank still assumes the full monthly commitment. Total waste unless you're clearing it completely — and if your balance is under $7–8k you might as well, since clearing it unlocks roughly $160 of borrowing capacity for every $1 of monthly HECS you remove.

    Do this: Balance under $8k and you're six months from a home loan? Clear it. Over $15k? Don't touch it — keep the cash for your deposit.

  5. 05

    If your investments beat indexation after tax, invest instead

    Indexation is capped at the lower of CPI or WPI — roughly 2.5–3.4% heading into 2026. A basic ASX/global ETF returning 7% pre-tax works out at about 4.8% after tax in the 32.5% bracket. Over 10 years, investing $20,000 instead of repaying it early can leave you $4,000–$7,000 ahead. HECS has no interest, just indexation — it's one of the cheapest "debts" you'll ever have.

    Do this: Run the numbers yourself in the Voluntary vs Invest calculator using your actual marginal tax rate before you decide.

  6. 06

    Don't expect salary sacrifice to shrink your HECS bill

    This is the most common bit of dodgy advice I hear. Yes, salary sacrificed super lowers your taxable income — but the ATO adds it back as "reportable super" when working out HECS. Novated leases reduce taxable income too, but they also create a Reportable Fringe Benefit (RFBA) that adds back in. Net effect: salary sacrifice is basically HECS-neutral. Use it for its super-tax benefits, not to dodge HECS.

    Do this: If someone tells you salary sacrifice will drop your HECS, ask them to show you the ATO page on repayment income. It won't.

  7. 07

    Moving overseas? Tell the ATO within 7 days

    Your HECS debt doesn't stay in Australia when you do. If you leave and earn above the AUD threshold ($67,000 for FY2025-26) you're still liable — and you have to lodge a worldwide income declaration each year. Skip it and you cop penalties plus interest. I've seen Aussies come back from London with five years of missed declarations and a $12k penalty bill on top.

    Do this: Before you fly, log into myGov → ATO → Update contact details → tell them you're moving. Lodge worldwide income by 31 October each year.

  8. 08

    Redirect your tax refund or bonus to HECS in May

    Lump-sum cash — your July tax refund, an annual bonus, EOFY commission — is the stuff that vanishes on random takeaway and holidays. If you route half of any big deposit straight to HECS in April or May, you wipe out a year of indexation on that chunk and you never miss the money because it was never in your everyday account.

    Do this: Set a rule with yourself: any single deposit over $2,000 in April or May gets split 50/50 — half to HECS via BPAY, half to your offset. Automate it if you can.

Frequently Asked Questions

Should I pay off HECS before saving for a house deposit?
Usually no. Partial HECS repayments don't change your compulsory repayment rate (which depends on income, not balance), so they don't improve lender serviceability unless they clear the debt entirely. Only pay off HECS first if your balance is under $5,000 (clearable in full) or your deposit is already at target.
Does a home lender care about my HECS balance?
Lenders care primarily about your compulsory repayment (an income-based percentage), not the balance itself. A $5,000 HECS balance on $80k income has the same repayment as a $50,000 balance on $80k income — so both reduce borrowing power equally. Clearing the smaller balance removes the deduction entirely; the larger one doesn't.
What is the First Home Super Saver Scheme?
FHSS lets first-home buyers make voluntary super contributions and later withdraw up to $50,000 of those contributions (plus deemed earnings) at concessional tax rates to fund a home deposit. It typically delivers a 15–30% effective tax benefit depending on your marginal rate.
