How to Reduce Inheritance Tax Legally

There is nothing dubious about reducing an inheritance tax bill. Every method in this guide uses allowances and reliefs that Parliament deliberately created, the annual gift exemption, the seven-year rule, charitable relief and the rest. Using them is tax planning, not avoidance or evasion, and it is exactly what the rules envisage.

A single thread runs through all seven tools below: time. Most reward starting early and acting steadily, which is why the best moment to begin is usually well before it feels urgent. This is general information rather than personal advice, and the right mix for you depends on your circumstances.

Why this is entirely legitimate

The families who pass on the most are usually those who take the trouble to understand and use what is available. None of the steps below involves anything artificial or aggressive: they are the everyday building blocks of estate planning, and HM Revenue & Customs expects people to use them. If you would like the full picture of how the tax works before diving into the tools, our complete guide to inheritance tax planning sets out the thresholds and mechanics in detail.

1. Use your allowances in full

Make sure you and your partner are using both nil-rate bands (£325,000 each) and the residence nil-rate band (up to £175,000 each where a main home passes to direct descendants), and that your wills are structured so none is wasted. For a married couple or civil partners, unused allowances transfer to the survivor, so getting the wills and the ownership of assets right can shelter up to £1 million between you. This is the starting point for everyone, and it costs nothing but careful arranging. Our answer on the inheritance tax threshold spells out exactly how the bands stack up.

Two details catch people out. The residence nil-rate band applies only to a main home left to direct descendants, and it tapers away once an estate passes £2 million, so a large estate can lose it altogether unless earlier planning brings the total down. And unmarried couples, however long together, do not inherit each other’s allowances at all. Checking that a will actually captures both bands, rather than assuming it does, is the cheapest worthwhile step in the whole of estate planning.

2. Give away £3,000 a year

The annual gift exemption lets you give away £3,000 each tax year with no IHT implications at all, and if you did not use last year’s, you can carry that single unused year forward, allowing up to £6,000 in one go. Separately, you can make small gifts of up to £250 to any number of different people each year, and give tax-free wedding gifts within set limits. None of these sounds dramatic, but used consistently across a family and over many years, they quietly move a meaningful sum out of your estate.

3. Give regularly out of income

This is one of the most valuable and least-used exemptions. Gifts made from genuine surplus income, not from capital, can be immediately exempt from IHT with no upper limit, provided they are regular in nature and do not reduce your own standard of living. Funding a grandchild’s school fees or topping up a child’s pension from spare pension income can qualify.

The key is evidence. HMRC will look for a pattern of gifts and proof that they came from income you did not need, so keeping a simple record of your income, your outgoings and the gifts you make is essential to claim it. For those with comfortable retirement incomes, this route can be remarkably powerful, and it pairs well with thinking about how you draw that income in the first place, which our guide on drawdown versus annuities covers.

To count, the gifts should be habitual rather than a single large transfer dressed up as regular. Setting up a standing order, say, a monthly contribution to a grandchild’s savings or a child’s pension, both creates the pattern and generates the paper trail. Because there is no seven-year clock and no upper limit, someone with a healthy surplus can move a substantial sum out of their estate over a decade entirely free of IHT, all while continuing to live exactly as they did.

4. Make larger gifts and survive seven years

Larger one-off gifts are “potentially exempt transfers”: they fall out of your estate entirely if you live for seven years afterwards. If you die within that window, the gift is brought back into the calculation, though a tapering reduction lightens the tax on gifts made between three and seven years before death. Planned early, while your health is good, this is one of the most powerful tools available.

5. Consider trusts

Trusts can remove assets from your estate while letting you retain a degree of control over how and when they are used, helpful when beneficiaries are young, vulnerable, or where you want to provide for a spouse while ultimately protecting children from an earlier relationship. They are genuinely useful but genuinely complex: different trusts carry different tax treatment, and some have their own periodic charges. They should always be set up with proper legal and financial advice, but for the right situation they can be very effective.

Be clear about what a trust is for. Its real strength is control and protection, shielding an inheritance from a beneficiary’s divorce or creditors, or providing for a disabled relative without disturbing their benefits, as much as any headline tax saving. Because a trust can carry its own charges, it should be chosen to solve a specific problem rather than adopted as a reflex. Matched to the right situation, though, it does something no gift can: it lets you move value out of your estate while still steering where it ends up.

6. Use your pension wisely

Pensions have traditionally sat outside your estate, so drawing on other savings first and preserving pension wealth to pass on has long been tax-efficient. Be aware, though, that from April 2027 most unused pension funds are due to be brought within the scope of IHT, which changes this calculation. Pensions remain central to sensible planning, but the old assumption that they are automatically IHT-free no longer holds, so keep your strategy current. Getting your pots organised first, as our guide on whether to consolidate your pensions explains, makes the whole picture easier to manage.

7. Give to charity

Gifts to charity are free of IHT, whether made in life or through your will. There is also a valuable incentive to give generously on death: if you leave 10% or more of your net estate to charity, the IHT rate on the rest of the estate falls from 40% to 36%. For the charitably inclined, this can mean more going to good causes while the cost to other beneficiaries is smaller than the headline gift suggests.

The arithmetic surprises people. Because the reduced rate applies to the whole remaining estate, crossing the 10% threshold can mean that giving more to charity costs your other beneficiaries very little, and sometimes leaves them scarcely worse off than if you had given nothing. The exact figures depend on the size of the estate, so this is a classic case where modelling the numbers before you finalise a will pays off. Our complete inheritance tax guide works through a full example that shows the effect in pounds.

The pitfalls to avoid

Putting it together

These seven tools are not alternatives, most estates use several at once, layered sensibly over time. A typical plan might use the allowances as its foundation, run a stream of gifts out of surplus income alongside, make a larger seven-year gift when the time is right, and add a charitable legacy in the will. The art is in the balance: reducing a future bill without giving away so much that your own security or comfort is at risk, and without tying up assets you may yet need. That is a judgement best made with someone who can see your whole picture.

A regulated financial adviser models the numbers and coordinates the strategy, usually alongside a solicitor for the wills and trusts. You can read more across our inheritance tax guides or find vetted specialists through the Devon inheritance tax planning hub. Every adviser we introduce is FCA-regulated and independently vetted, and matching with one through us is free, a straightforward way to turn these general principles into a plan built around your own family.
