The end of financial year (EOFY) is when a year of debt recycling becomes a tax return. A short checklist before and after 30 June keeps the deduction clean and the paperwork simple.
Most EOFY work for debt recycling happens after 30 June, when statements arrive. A few decisions have to be made before then, so start in early June.
Before 30 June
The deduction rests on what each borrowed dollar was used for, the principle behind how debt recycling works. Each item below helps prove that use.
Check that each investment split was used only to invest this year
List any new splits, redraws and purchases, with dates and amounts
Decide with your accountant whether to prepay interest
Confirm investment income was paid onto the home split or its offset
Note any fixed rate or interest-only period ending in the next 12 months
Prepaying Interest
The Australian Taxation Office (ATO) lets individuals claim prepaid investment interest in the year it is paid if two conditions are met. The period covered must be 12 months or less, and it must end by the last day of the next income year.
If either condition is not met, the deduction is spread over the period the payment covers. Not every lender or loan type allows interest to be prepaid, so check before you plan around it.
Prepaying moves a deduction forward. It also takes cash out of your offset or buffer, so it is a timing decision for your accountant, not a default step.
Statements for Each Split
After 30 June, get an interest statement for every split. Each one should show its own account number, balance and interest charged for the year.
Record
Why It Matters
Investment split interest statements
Show the interest you may be able to claim
Home split statement
Shows the home debt is separate, and that income and refunds were paid onto it
Redraw and transfer records
Link each drawdown to the investment it bought
Prepaid interest receipt
Supports the timing of that deduction
Separate account numbers for each purpose make this step quick. They are a core part of how we structure the loan.
Interest Apportionment
If any part of an investment split was used for something private, the ATO requires the interest to be apportioned between the investment and private portions. Repayments must also be apportioned across both portions, so you cannot choose to repay only the private part.
One private redraw can therefore affect every later year of that split. Our guide to the redraw contamination trap explains how it happens and how to avoid it.
If you find a private redraw, tell your accountant rather than leaving it out. They work out the deductible share.
Investment Income Records
Your accountant also needs the income your investments produced and any purchases or sales.
Dividend and distribution statements for shares, exchange traded funds (ETFs) and managed funds
Rental statements and expense records for any investment property
Contract notes or settlement statements for anything bought or sold
The ATO generally requires investment records to be kept for five years after your return is processed. Records of what you paid for an asset are kept until five years after you sell it.
What to Send Your Accountant
One tidy bundle saves time and reduces the chance of an error. Send:
The interest statement for every split, home split included
A note of each new split or redraw: date, amount and what it bought
Income statements and contract notes from the year
Any prepaid interest receipt
Earlier apportionment workings, if a split was ever used privately
If you lodge your own return, it is due by 31 October. A registered tax agent can generally lodge later, provided you engage them before 31 October.
Using the Refund
The refund is part of what keeps debt recycling moving. Paid onto your home loan, it reduces the debt you cannot claim.
If you plan to recycle it, pay it onto the split set up for that purpose and redraw it from there to invest, so the trail stays clean. Your financial adviser guides the investment decision, and Kingfisher arranges the lending without giving tax advice.
Plan the Year Ahead
If this year showed your lender cannot keep splits separate or pay redraws to an investment account, refinancing for debt recycling may be worth reviewing before the next cycle.
The year ending 30 June 2027 is also the last before new capital gains tax (CGT) rules start. From 1 July 2027, the 50% CGT discount for individuals, trusts and partnerships is replaced with inflation indexation and a 30% minimum tax. Gains that accrued before that date keep the 50% discount.
The Budget explainer says an asset's value at 1 July 2027 can be set by a valuation or an ATO formula. Ask your accountant whether you need a record of your investments' values at that date.
The Bottom Line
A debt recycling EOFY routine is mostly about proof. Settle any prepaid interest question before 30 June, collect a statement for every split, flag any private use, and give your accountant one tidy bundle. Then put the refund back to work on the home loan.

Frequently Asked Questions (FAQs)
In early June. Decisions such as prepaying interest need to be made before 30 June, and the statements and income records follow after the year ends.
Possibly. The ATO allows a deduction in the year paid for prepaid interest covering 12 months or less that ends by the end of the next income year, but not every lender or loan allows it.
Tell your accountant. The ATO requires the interest to be apportioned between the investment and private portions of the loan.
It makes the job much simpler. A statement per split shows the interest on each purpose and makes the deductible amount clear.
The ATO generally requires five years after your return is processed. Keep purchase records until five years after you sell the investment.
By 31 October if you lodge it yourself. If you use a registered tax agent, engage them before 31 October and they can generally lodge later.
Paying it onto your home loan reduces non-deductible debt. If investing it is part of your plan, it can then be redrawn through the split set up for that purpose.
