Grandparents caring for grandchildren: Centrelink, super, education funding, and estate planning

Many Australian grandparents play meaningful financial and practical roles in their grandchildren's lives — some as full-time carers, some as regular childminders while parents work, some as the primary funders of private school fees. Each of these roles has specific financial dimensions that affect Centrelink entitlements, superannuation, tax planning, and estate arrangements. Understanding the framework helps grandparents make choices that are both generous and financially sound.

The most intensive form of grandparent care is full custodial or kinship care — where grandchildren live with grandparents, typically due to parental absence, incapacity, or family breakdown. Grandparents in this position are entitled to access the same Centrelink family payment streams as any other primary carer: Family Tax Benefit Part A (for the cost of raising dependent children, income-tested) and Family Tax Benefit Part B (for sole-income or sole-carer households, income-tested on the higher earner). The most valuable practical resource for grandparents in these circumstances is the Grandparent, Foster and Kinship Carer Adviser Service at Services Australia — a free specialist advisory service that provides tailored information about payments, arranges appointments with specialist staff including social workers and Financial Information Service Officers, and makes referrals to community service providers. They can be reached on 1800 245 965 (Services Australia, https://www.servicesaustralia.gov.au/grandparent-foster-and-kinship-carer-advisers). Many grandparents in custodial care are not accessing the full payments they are entitled to simply because they don't know the service exists.

Where grandparents provide regular but non-custodial care — looking after grandchildren during parents' work hours, after school, during school holidays — the financial effect is primarily on the grandparent's own work and superannuation. Reducing or stopping paid work to provide care reduces employer superannuation guarantee contributions and personal income. For grandparents who can keep working even part-time, the impact on super can be mitigated; for those who stop work entirely, catch-up concessional contributions (available where total super balance is under $500,000) provide a mechanism to restore super balances when paid work resumes. Where one partner works and the other provides care, the spouse contribution offset — available for contributions made to a low-income spouse's super, up to $540 offset on $3,000 of contributions — remains available even in this context.

Education funding for grandchildren is a common and generous form of support, and it benefits from being structured properly. The simplest approach is direct cash gifts to parents or grandchildren, but grandparents who receive or expect to receive the Age Pension need to understand the Centrelink deprivation (gifting) rules. The allowable annual limit is $10,000 per year and $30,000 over any rolling five-year period — for the couple combined, not per individual (Services Australia, https://www.servicesaustralia.gov.au/how-much-you-can-gift?context=22526). Amounts above these limits are assessed as deprived assets under the assets test for five years from the date of transfer. For a grandparent couple paying $40,000 per year in private school fees, only $10,000 can pass through the gifting channel without Centrelink consequence — the remaining $30,000 would create a deprivation assessment. Note that the deprivation rules only apply to people who receive or are eligible for means-tested payments; grandparents whose assets and income are well above the pension threshold are unaffected by deprivation rules.

There are structural alternatives for long-term education funding that sidestep the annual gifting constraint. Education investment bonds (sometimes called insurance bonds) accumulate with a specific tax structure: investment earnings are taxed within the bond at up to 30 per cent during the accumulation period, but after ten years, withdrawals are tax-free to the holder. They can be set up in a grandchild's name or with grandparents as the owner, used specifically for education expenses, and not subject to the Centrelink gifting rules in the same way as direct cash transfers (the contribution to the bond is the gift, not the ongoing value). Family trust distributions are a further option where a family trust already exists — distributions to grandchild beneficiaries must be handled with care for the unearned income (Division 6AA) rules that apply to minors, which tax income above a low threshold at 47 per cent where it is not from work or employment. Advice from a tax specialist is needed before relying on this structure.

Estate planning for grandchildren warrants specific attention. A straightforward will leaving assets to adult children (the grandchildren's parents) passes assets through an extra generation and risks those assets being absorbed by the children's financial arrangements, divorces, or creditors. For grandparents who want assets to benefit grandchildren specifically — particularly minor grandchildren — a testamentary trust within the will is the standard tool. A testamentary trust comes into existence on the testator's death and holds the bequest in trust until the grandchild reaches a nominated age (commonly 18 or 25), with the trustee having discretion over distributions in the interim for education, maintenance, and benefit purposes. Testamentary trusts also provide significant tax advantages for income distributed to minor beneficiaries, as income from a testamentary trust is taxed at adult rates rather than the penalty rates that apply to minors' investment income.

Superannuation death benefits can also be directed to grandchildren, but the mechanism is more restricted. Grandchildren are generally not "dependants" for super death benefit purposes unless they are financially dependent on the deceased at the time of death; they do not automatically receive the tax-free treatment that applies to a spouse or minor dependent child. Superannuation death benefit nominations that attempt to direct large balances to adult grandchildren need to be reviewed with advice, as the tax consequences and the legal mechanism both require care.

For grandparents providing substantial financial support to grandchildren, the core planning steps are: understand what Centrelink supports are available and access them (particularly for custodial carers via the Adviser Service); structure education funding through appropriate vehicles to minimise Centrelink gifting exposure and tax; review estate planning to include grandchild-specific provisions; and ensure superannuation nominations reflect actual intentions. Each of these is straightforward with specialist advice and potentially costly to get wrong.
