Passing wealth to your children is one of the most meaningful financial decisions you'll make — but without some planning, a significant portion can be lost to tax. The good news is that the UK tax system offers several legitimate ways to reduce what HMRC takes. The right approach depends heavily on your circumstances, but understanding the landscape puts you in a much stronger position to plan well.
When you leave money or assets to your children, three main taxes can come into play: Inheritance Tax (IHT), Capital Gains Tax (CGT), and in some cases Income Tax. Each works differently, and the strategies that help with one don't always help with another. Effective planning means understanding which taxes apply to your situation and using the available reliefs and exemptions before they're needed — not after.
Inheritance Tax is typically the biggest concern for families looking to pass on wealth. It applies to the value of your estate above a certain threshold when you die, charged at a standard rate on the excess. Your estate includes everything you own: property, savings, investments, and certain gifts made in the years before your death.
Several factors affect how much IHT an estate faces:
The interaction between these allowances means some estates pay no IHT at all, while others face a substantial bill. Estate size, family structure, and asset type all shape the outcome.
One of the most straightforward ways to reduce an IHT bill is to give money away while you're alive. The key principle: most gifts become exempt from IHT if you survive for seven years after making them. This is known as a potentially exempt transfer (PET).
There are also annual exemptions that allow you to give away certain amounts each tax year immediately free of IHT, without needing to survive seven years. Smaller regular gifts, wedding or civil partnership gifts, and gifts from surplus income (not capital) each have their own rules and limits.
What matters here: the size of the gift, your relationship to the recipient, and whether the gift is genuinely out of your regular income or drawn from capital.
Trusts are legal arrangements where assets are held by trustees for the benefit of your children (or other beneficiaries). They're not just for the very wealthy — they're used for a wide range of estates as a way to control how and when money is passed on, while potentially reducing tax exposure.
Different types of trusts have different tax treatments:
| Trust Type | Broad Use Case | Key Tax Consideration |
|---|---|---|
| Bare trust | Simple, direct transfer to a child | Beneficiary taxed as owner |
| Discretionary trust | Flexibility over who benefits and when | Subject to IHT periodic charges |
| Interest in possession trust | Beneficiary receives income | Complex IHT treatment |
| Loan trust | Lending rather than gifting assets | Limits IHT growth on the lent sum |
Trusts involve legal and administrative complexity and ongoing costs. Whether one is appropriate depends on the size of your estate, your intentions, and your family's circumstances.
Many people don't realise that defined contribution pension funds can be a powerful way to pass money to the next generation. In many cases, money held inside a pension sits outside your estate for IHT purposes, meaning it can be passed on more efficiently than assets held elsewhere.
The rules around this are changing — the government has announced reforms to how pensions interact with IHT — so this is an area where current professional advice is especially important. The general principle of keeping pension pots separate from estate planning still holds, but the specifics are evolving.
Life insurance can be used to cover an expected IHT bill, so that your children receive the full value of the estate rather than having to sell assets to pay the tax. The critical detail: the policy must be written in trust, so the payout doesn't form part of your estate itself and increase the IHT liability.
This doesn't reduce your IHT bill — it funds it. Whether this makes sense depends on your health, the size of the expected liability, and the cost of premiums over time.
If you own a qualifying business or agricultural land, Business Property Relief (BPR) or Agricultural Property Relief (APR) may significantly reduce the IHT on those assets, sometimes to zero. These reliefs are subject to conditions around how long you've held the assets and how they're used. Not all business or agricultural assets automatically qualify.
When you give assets (rather than cash) to your children, you may trigger a Capital Gains Tax liability — even though no money changes hands. HMRC treats the gift as if you sold the asset at its current market value.
This applies to things like shares, investment property, and other assets that have grown in value. Each person has an annual CGT allowance, but above that threshold, gains are taxed at rates that vary depending on the asset type and your income level.
The interaction between CGT and IHT planning is genuinely complex. What saves IHT can sometimes create a CGT event, and vice versa. This is one reason why strategy needs to be considered as a whole, not as separate decisions.
No single strategy works for everyone. The variables that determine what makes sense include:
Tax efficiency is rarely the only objective. Many families balance it against maintaining financial security, treating children equitably, and keeping things simple enough to actually manage.
Estate planning sits at the intersection of tax law, trust law, and family financial planning. The rules change — sometimes significantly — and the wrong move can create unintended tax bills or legal complications. A qualified financial planner, in conjunction with a solicitor experienced in estate planning, can assess your specific situation and recommend a strategy that accounts for all the moving parts.
Understanding the landscape — which this article covers — is a genuinely useful starting point. But applying it to your own estate requires someone who can see your full picture.
