Family & retirement planning
If your adult child is buying a first home, you may be asked to help. Here is what a gift, a loan or a guarantee can mean for your own retirement plan, and who to involve before any money moves.
Your adult child is trying to buy a first home, the deposit is the hard part, and you would like to help. They may have asked, or you may have offered first.
Conversations like this usually start with an amount, but the form the help takes can matter as much. A gift, a written loan and a guarantee can involve similar sums and reach very different parts of your plan: your retirement income, your own borrowing and your home.
Both rates and prices have moved this year. As at 30 October 2026, the Reserve Bank had most recently raised the cash rate target by 25 basis points to 4.60% on 29 September 2026, and Cotality’s national Home Value Index fell 1.1% in September, a sixth straight monthly fall, leaving values 5.2% below their March 2026 peak.
Since 1 October 2025 the 5% Deposit Scheme has had no income caps, no waitlist and no lenders mortgage insurance, and places are unlimited. The minimum deposit is 5%, or 2% for single parents and legal guardians. The Government guarantee is to the lender, so your child stays responsible for repayments and must still meet the lender’s credit policy. Price caps depend on location: in capital cities and listed regional centres they are $1.5 million in New South Wales, $950,000 in Victoria and $1 million in Queensland.
Help to Buy works differently: the Government contributes up to 30% of the price of an existing home or 40% of a new one, with a 2% minimum deposit and 10,000 places a year. It has its own price caps. Taxable income caps from 1 July 2026 are $103,000 for a single applicant and $165,000 for joint applicants or a single parent. This is shared equity: the Government holds an equity share, so your child should understand the ongoing conditions and how that share can be bought back.
Banks generally assess repayments using an interest rate at least 3 percentage points above the loan rate. A smaller deposit leaves less cushion if values keep falling. Your child’s broker can explore whether either scheme fits, and what each option costs.
Services Australia’s Age Pension gifting free areas are $10,000 in one financial year and $30,000 over five financial years. These limits apply to a couple combined, rather than separately to each partner. The excess is counted in the assets test and deemed (treated as earning a set rate) in the income test for five years from the gift, so timing matters if you could claim the pension, or already receive it, within that window.
Money you lend counts in both tests, and forgiving the loan later may be treated as a gift. Tax on any interest you charge is a question for your accountant.
A guarantee involves no payment up front, but Moneysmart says a guarantor may have to repay the whole loan plus interest, the lender may sell a home used as security, and a default may be recorded on the guarantor’s credit report. A partial guarantee may limit what you owe, but the security is still at risk. Moneysmart suggests independent legal or financial advice before signing, and a solicitor can take you through the guarantee itself.

The Code also requires a notice that you can refuse to sign and can limit your liability. Unless you or your lawyer confirm you’ve had independent legal advice, the bank takes reasonable steps to meet you without the borrower present. Use those days for that advice, and ask the lender exactly how much you’d be guaranteeing and when it ends.
None of this needs settling in one sitting.

Helen and Mark are fictional, and this example is for illustration only. They are 58 and 57, own their home outright, have super and some shares, and don’t expect to claim the Age Pension within five years. Their daughter Claire, 29, and her partner Arun want to buy in Sydney. They also have a son, Josh.
Their first instinct: a $60,000 gift plus a guarantee over part of Claire’s loan, secured on their home.
Their Ryker financial adviser started with Helen and Mark’s plan, not Claire’s purchase. They want to stop full-time work at 63, and in the adviser’s projections a $35,000 gift left that date in place. A $60,000 gift pushed it later.
A written loan would keep a claim on the money but count as their asset for the Age Pension, and lending another $25,000 only worked if it came back on a written schedule. The guarantee would put the home they plan to retire in behind a loan they couldn’t control.
Questions for their accountant: tax on any interest from the loan, and on selling shares to fund the gift. For Claire’s broker: the lending options open to her and Arun and their costs, and whether either scheme reduces the help needed. For a solicitor: the loan agreement.
They agreed on a $35,000 gift, subject to confirming the tax implications of selling shares, and no guarantee for now. The proposed $25,000 loan remained conditional on testing delayed or missed repayments against their retirement plan and having a solicitor prepare the agreement. They also agreed to discuss how support for Claire would be reflected in their plans for Josh.
How much could we give without moving our retirement date or running down our cash reserve?
What is the most we could owe as guarantors, and could we pay it without selling our home?
If we lend the money, how should the loan be treated in our wills?
