Family Loan to Invest: 2026 Rules You Must Know

By The Chipkie Team, Personal Finance Editorial Team  ·  Last updated 11 October 2026

Money inside families is doing a lot of heavy lifting right now. With property prices stretched and sharemarket investing easier than ever through apps, it has become common for parents to hand an adult child capital to get started. But a family loan to invest is a very different animal from a gift, and the difference decides who pays tax, who claims the interest, and — when markets turn — who wears the loss.

Australia has no gift tax and no inheritance tax, so the question is almost never “will the ATO tax the transfer?” It is “can anyone prove what this money actually was?” That is where families come unstuck.

Key Takeaways

• Australia has no gift tax and no inheritance tax, so transferring money to family is not a taxable event in itself — but the loan-versus-gift distinction drives tax, Centrelink and legal outcomes.
• A borrower can generally only claim an interest deduction where they actually pay interest on borrowed funds used to produce assessable income; the lender must declare that interest as income.
• Under a genuine loan, the borrower bears the investment loss and still owes the full principal — the debt does not shrink because the shares did.
• If the money is used for a property deposit, lenders treat a repayable family loan as a liability, and signing a gift letter or statutory declaration that falsely calls it a gift is fraud.
• Division 7A only applies where a private company lends to a shareholder or associate — not to ordinary loans between family members as individuals.

What exactly is a family loan to invest, and how is it different from a gift?

A family loan to invest is money advanced by a relative on terms requiring repayment, which the borrower then uses to buy income-producing or growth assets. A gift is unconditional and never comes back. The label matters because it determines repayment obligations, deductibility, estate outcomes and how Centrelink assesses the lender’s assets.

The three structures families actually use look similar on a bank statement but behave very differently:

One important clarification: ordinary lending between individuals is not regulated consumer credit. The National Consumer Credit Protection Act regime applies to those providing credit in the course of a business. Your father is not required to hold a credit licence. That is freedom, not protection — there is no responsible lending safety net, no hardship framework and no AFCA complaint pathway if things sour.

How does the ATO treat interest when family members lend money for shares?

The ATO’s position follows the use of the funds. Where a borrower genuinely pays interest on money borrowed to acquire income-producing assets, that interest is generally deductible. The family lender must declare interest received as assessable income in their own tax return. An interest-free loan produces no deduction and no income.

Practical consequences most families miss:

• Lending money for shares does not transfer the tax. Dividends, franking credits and capital gains attach to the registered holder of the shares, not to whoever supplied the cash.
• Interest-free is not always generous. If the borrower is on a high marginal rate and would otherwise deduct the interest, a commercial-rate loan can leave the family better off overall. Our experience across agreements users create shows this is the single most common missed optimisation.
• Capital gains are the borrower’s. According to the Australian Taxation Office, individuals who hold an asset for more than 12 months generally access the 50% CGT discount — a reason not to force a repayment schedule that pushes a sale inside twelve months.
• Division 7A is a company issue only. If the lender is a private company rather than Mum and Dad personally, Division 7A loan agreement requirements apply and an unpaid advance can be treated as a deemed dividend.

Document the purpose of the funds in writing on day one. Reconstructing an interest deduction three years later from a bare bank transfer is how disputes with the ATO start.

Who bears the loss if the family loan investment goes backwards?

Under a genuine loan, the borrower bears the loss entirely. If a parent lends $80,000 for a share portfolio that falls to $50,000, the borrower still owes $80,000 plus any agreed interest. The debt is fixed; the asset is not. Families who do not want that outcome need a joint investment, not a loan.

This is the “who bears the loss” question that destroys relationships, and it should be answered explicitly in the document before a cent moves. Your realistic options:

1. Pure loan. Borrower carries all downside and keeps all upside above the interest cost.
2. Joint investment with a co-ownership agreement. Gains and losses split by agreed percentage. No debt, but you need an exit mechanism and a valuation method.
3. Loan with a documented hardship clause. Still a loan, but with a defined right to pause repayments or extend the term in agreed circumstances.
4. Secured loan. The lender takes security over the asset, improving recovery but adding registration obligations.

Also consider the clock. Limitation periods in each state and territory cap how long a lender has to sue on an unpaid debt, and an undocumented advance can quietly become unenforceable. The trap is explained further in our guide to the statute of limitations on family loan agreements.

What happens if the borrowed money goes toward a property deposit?

It changes everything. Australian lenders assess the source of deposit funds, not just the amount. A repayable family loan must be disclosed as a liability, reduces assessable borrowing capacity, and many lenders will decline the application outright or require the family debt to be formally subordinated or repaid first.

Lenders typically require a gift letter or statutory declaration confirming that family funds are non-repayable, and most want to see the deposit “genuinely saved” or seasoned in the account for a period. Here is the line you cannot cross:

• A gift letter is false if there is any side arrangement requiring repayment, any expectation of repayment, or any written loan agreement sitting in a drawer.
• Signing a false declaration to obtain credit is fraud. It exposes you to criminal charges, immediate loan default, and the lender’s right to call in the entire facility.
• If the money is genuinely a loan, say so. Disclose it, accept the reduced borrowing capacity, and structure around it.

One more trap for parents on a means-tested payment: if you are receiving the Age Pension and you forgive the loan or simply gift the money instead, Centrelink gifting rules bite. As set out by ASIC’s MoneySmart and Services Australia, you can gift $10,000 per financial year, capped at $30,000 over five financial years. Anything above that is counted as a deprived asset for five years. This is a social security rule — not a tax limit.

What should an investment loan agreement between family members contain?

A workable family investment loan agreement needs the commercial terms a bank would insist on, plus the relationship terms a bank never thinks about. Written, signed and dated before funds transfer. Verbal arrangements are provable in court but expensive and ugly to litigate, and they routinely fail on the detail.

• Principal, transfer date, and the specific permitted purpose of the funds
• Interest rate, or an express statement that the loan is interest-free (see our guidance on setting a fair interest rate on a family loan)
• Repayment schedule, or a clear trigger such as sale of the asset
• Who bears investment losses, stated in plain words
• Whether repayment accelerates if the asset is sold early
• Security, if any, and how it is registered
• What happens on the lender’s death — forgiven, or repayable to the estate?
• What happens on the borrower’s relationship breakdown, so the debt is recognised in a property settlement
• Hardship and default process, including notice periods

What else do families most often ask about lending to invest?

The questions below come up repeatedly, and each one turns on the same underlying issue: whether the arrangement is documented well enough to prove what the parties actually intended.

Does the ATO need to be told about a family loan to invest?

There is no notification form — Australia has no gift tax and no equivalent of a US gift tax return. However, interest paid must be declared as income by the lender, and any interest deduction claimed by the borrower must be substantiated. Keep the agreement, bank records and evidence of how the funds were used.

Can my parents charge me interest on money lent for shares?

Yes. Private individuals may agree any lawful rate. A commercial rate can be tax-efficient, because the borrower may deduct interest on funds used to produce assessable income while the lender declares it. Record the rate in writing and keep evidence that payments were actually made, not merely accrued on paper.

If the investment loses money, can the loan simply be cancelled?

The lender can forgive the debt, but it is a decision, not an automatic consequence. Forgiveness may affect the lender’s estate planning, and for a lender receiving a means-tested payment it can be assessed under Centrelink gifting rules. Build any loss-sharing intention into the agreement upfront instead.

Does a family loan affect my future borrowing capacity?

Yes. Any repayable debt is assessed as a liability when you apply for a mortgage or other credit, reducing your serviceability even if repayments are informal or paused. Lenders stress-test against the full outstanding balance. Disclose it honestly — concealment discovered during verification generally ends the application.

Where to from here?

Lending within a family to build wealth is a legitimate, powerful strategy. It fails for one reason almost every time: nobody wrote down what the money was. Decide whether it is a loan, a gift or a joint investment, name who carries the downside, and get it signed before the funds move.

If you are ready to put it on paper, you can create a clear, legally sound family investment loan agreement in minutes — with repayment terms, interest and loss-sharing spelled out, so the relationship survives whatever the market does next.
