In an era of rising education costs, uncertain housing markets, and increasing life expectancy, many parents and grandparents are looking for ways to financially support younger generations. But doing so wisely means not just saving — it means saving tax-efficiently. Whether your goal is to help with university fees, a first home, or long-term financial security, there are several tools available to help you.

Junior ISAs: Simple, Tax-Free Growth

The Junior ISA (JISA) is one of the most straightforward and tax-efficient vehicles for saving for children. Available to children under 18, JISAs allow for contributions up to £9,000 per year with all growth and income completely tax-free.

Only a parent or guardian can open the account, but anyone can contribute, making it ideal for grandparents. At 18, the child gains full control, but prior to that, no-one can access the money. This makes JISAs particularly suitable for long-term goals like university or a first home.

JISAs are particularly useful for higher-earning parents – if a child earns more than £100 (outside of a JISA) in interest from money gifted by a parent, the parent may be liable for tax This rule doesn’t apply to grandparents, making JISAs especially attractive for intergenerational gifting.

Junior SIPPs: Investing in Their Retirement

For those thinking decades ahead, how about a pension (e.g. Self-Invested Personal Pension [SIPP] for a child? They offer unmatched long-term tax advantages. You can contribute up to £2,880 annually, and HMRC adds 20% tax relief, bringing the total to £3,600.

Funds are locked until the child reaches age 57+, making this a gift for their future retirement. While it’s not suitable for short-term goals, the long investment horizon allows for compound growth and tax-free returns on both income and capital gains.

A contribution to a SIPP might be particularly attractive for grandparents who want to reduce inheritance tax by gifting during their lifetime, while ensuring the funds are used responsibly.

Premium Bonds: Sentimental and Safe

While not technically an investment, Premium Bonds remain a popular choice for grandparents. Backed by NS&I, they offer tax-free prizes instead of interest. Capital is protected, but returns are random — many bonds earn nothing.

They’re best suited for gifts where security is paramount and growth is secondary. Over time, inflation may erode the real value, so they’re not ideal for long-term wealth building.

Trust-Based Life Policies and Estate Planning

For those with significant assets, trust-based life policies and discounted gift trusts (DGTs) can be powerful tools to reduce inheritance tax.

These strategies are complex and require advice, but they could be particularly useful for high-net-worth individuals looking to future-proof their estate and ensure wealth is passed down efficiently.

Gifting and Inheritance Tax Exemptions

UK tax rules allow individuals to gift up to £3,000 per year without it counting towards the value of their estate for inheritance tax purposes [2]. You can also make small gifts of up to £250 to any number of people, and regular gifts from income may be exempt if they don’t affect your standard of living.

These exemptions can be used alongside savings accounts, ISAs, or trusts to build a tax-efficient strategy that supports your loved ones while reducing your estate’s tax liability.

Teaching Financial Responsibility

Beyond financial mechanics, it’s vital to educate children about money. Engage them in discussions about saving, investing, and long-term goals. This not only prepares them to manage their inheritance but also instils values that last a lifetime.

Final Thoughts

Saving for children and grandchildren is more than a financial gesture — it’s a legacy. By using tax-efficient tools like Junior ISAs, SIPPs, trusts, and strategic gifting, you can maximise the impact of your contributions while minimising tax liabilities.

Start early, stay consistent, and seek advice where needed. Whether it’s £25 a month or a larger lump sum, the key is to begin — because time, more than anything, is your greatest ally.
