Identical interest savings. Very different tax, flexibility and cost. If there’s any chance you’ll rent the property out one day, this decision matters a lot.
Both save you identical interest — dollar for dollar. Offset keeps your money as “savings” (flexible access, preserves loan balance, best for future investors). Redraw treats it as extra repayments (simpler, usually free, reduces loan balance). If you might ever rent the property, choose offset — it protects your future tax deductibility.
Both features reduce the interest you pay by temporarily lowering the balance that interest is calculated on. If your loan is $500,000 and you have $50,000 sitting in either offset or redraw, the lender charges interest only on $450,000 that month. The saving is identical.
Where they differ is the plumbing — and that plumbing has real tax and flexibility consequences.
| Feature | Offset account | Redraw facility |
|---|---|---|
| What it is | A separate transaction account linked to the loan | A feature on the loan itself that lets you pull extra repayments back out |
| Interest saving | Same as redraw | Same as offset |
| Access | Instant (debit card, online, BPAY) | Varies: online instant at some lenders; form + 1–3 days at others |
| Effect on loan balance | Loan balance stays the same | Loan balance drops (you’ve “repaid” extra) |
| Future tax deductibility (if rented out later) | Full original balance remains deductible | Only remaining (reduced) balance deductible — deductibility leaks away |
| Typical cost | $200–$400/year package fee or $10/month | Usually free |
| ATO treatment of withdrawals | Savings withdrawal — no tax event | New borrowing — re-borrowed amount must be used for a deductible purpose to stay deductible |
| Best for | Future investors, high cash balances, tax-sensitive borrowers | Simple owner-occupiers with smaller balances, fee-sensitive borrowers |
This is the point most people get wrong. Say you buy a $600K home with a $500K loan. Over 5 years you push $200K into your loan via redraw. Then life changes — you move, rent the property out, and buy somewhere new.
On a $200K difference, that’s roughly $12,000/year in deductions at 6% interest — a $4,000–$5,000/year difference in tax paid, for the same amount of money in the same place.
Yes, and many Australians do. A common split:
This is often the best of both worlds — but only works if the loan product offers both, and if the package fee is justified by your offset balance.
Offset is a separate transaction account linked to your loan — funds stay as “savings”. Redraw is a feature on your loan itself — funds are classified as “extra repayments” you can access. Both reduce the interest you pay by the same amount, dollar-for-dollar.
They save the exact same amount. If you have $50,000 offsetting a $500,000 loan at 6%, you save about $3,000/year either way. The difference is flexibility and tax treatment, not interest savings.
Yes — and this is the critical one. If you later convert your home to an investment, interest is only tax-deductible on the actual loan balance. Redraws reduce the balance (bad for future deductibility), while offset keeps the balance intact (good). For any chance of future renting, always use offset.
Usually yes. Offset typically comes as part of a “package” loan with $200–$400 annual package fee, or a $10/month add-on. Redraw is almost always free. On a loan under $200K the package fee may outweigh the interest savings — redraw wins there.
Yes, on most variable-rate loans. You can have extra repayments sitting in redraw AND a separate offset account — many Australians do exactly this for tax flexibility and emergency access respectively.
Yes. Offset is a transaction account — withdrawals are instant, usually via debit card or online transfer. Redraw access varies by lender: some online instantly, some require a form and take 1–3 days.
