How to Reduce Inheritance Tax: 10 Legal Ways to Cut Your IHT Bill

Inheritance tax is often called a "voluntary tax" because with proper planning, many people can legally reduce or eliminate it. The key is understanding the rules and acting early enough for strategies to work.

Here are 10 legitimate ways to reduce the inheritance tax your estate will pay – from simple steps anyone can take to more sophisticated planning for larger estates.

Understanding IHT First

Before reducing IHT, understand when it applies:

• IHT is charged at 40% on estates above £325,000 (the nil-rate band)
• An extra £175,000 is available when leaving your home to direct descendants
• Unused allowances can transfer between spouses
• Maximum combined allowance for a married couple: £1 million

If your estate is under these thresholds, you may not need to worry about IHT at all. But with property values rising, more estates are being caught.

1. Use Your Annual Exemptions

How it works: You can give away £3,000 per year completely free of IHT. Plus, you can give £250 to any number of other people.

The strategy: Use your £3,000 allowance every year. If you didn't use last year's, you can carry it forward once, making £6,000 in one year. Over time, this adds up significantly.

Example: A couple using both their allowances gives away £6,000 per year. Over 10 years, that's £60,000 removed from their estate, saving £24,000 in IHT at 40%.

Key point: You must actually give the money away. You can't give £3,000 to your child who then pays for your shopping.

2. Make Regular Gifts from Income

How it works: Gifts made from your income (not capital) are immediately exempt if they're regular, don't affect your standard of living, and form part of normal expenditure.

The strategy: If your pension or investment income exceeds your expenses, regularly gift the surplus to family. This could be paying grandchildren's school fees, covering a child's mortgage, or regular payments into a savings account for them.

Example: Your pension is £40,000/year but you only spend £30,000. You regularly give £10,000/year to your children. That's £10,000/year leaving your estate immediately tax-free – no 7-year wait.

Key point: Keep records. You need to show it's regular, from income, and doesn't affect your living standards. HMRC can ask for evidence.

3. Make Larger Gifts (7-Year Rule)

How it works: Gifts beyond annual exemptions become fully exempt if you survive 7 years. If you die within 7 years, the gift uses up your nil-rate band or is taxed on a sliding scale.

The strategy: If you're in good health and have assets you don't need, consider making significant gifts to the next generation now rather than at death.

The taper:

• 0-3 years: 40% tax
• 3-4 years: 32% tax
• 4-5 years: 24% tax
• 5-6 years: 16% tax
• 6-7 years: 8% tax
• 7+ years: 0% (fully exempt)

Key point: You must genuinely give the asset away. If you give your house to your children but continue living in it rent-free, it's a "gift with reservation" and stays in your estate.

4. Plan for Both Deaths (Not Just First)

How it works: Everything passing to a spouse is tax-free, and unused nil-rate band transfers to the survivor. But the real IHT bill comes when the second spouse dies.

The strategy: Don't just rely on the spouse exemption – plan for what happens at the second death. Consider:

• Making gifts from the first spouse's estate to use their nil-rate band
• Life interest trusts that use the first spouse's allowance while providing for the survivor
• Insurance to cover the eventual IHT bill

Example: Rather than leaving everything to your spouse (who then has a £2 million estate and a £1 million IHT bill), consider trusts or gifts that use allowances at the first death.

5. Leave Money to Charity

How it works: Gifts to charity are completely exempt from IHT. Even better, if you leave at least 10% of your net estate to charity, the IHT rate on the rest drops from 40% to 36%.

The strategy: If you were planning to leave something to charity anyway, leaving at least 10% can actually increase what your family receives by reducing the tax rate.

Example: Net estate £1 million. No charity gift: 40% on £675,000 = £270,000 tax, family gets £730,000. With 10% charity (£100,000): 36% on £575,000 = £207,000 tax, family gets £693,000, charity gets £100,000. Total distributed £793,000 vs £730,000.

6. Business Property Relief

How it works: Qualifying business assets can attract 50% or 100% relief from IHT. This includes unquoted trading company shares, partnership interests, and some AIM shares.

The strategy: If you have cash that would otherwise be in your estate, investing in qualifying businesses (held for at least 2 years) can effectively remove it from IHT.

Warning: This involves investment risk. Don't invest in unsuitable assets just for tax relief. Get professional advice.

7. Write Life Insurance in Trust

How it works: If life insurance is paid to your estate, it increases the IHT bill. If it's written in trust, the payout goes directly to beneficiaries outside your estate.

The strategy: Put any life insurance policies in trust. Most insurers offer trust forms free of charge. It costs nothing and could save thousands in IHT.

Also consider: A "whole of life" policy to cover the expected IHT bill. The payout (in trust) provides cash to pay the tax, meaning assets don't need to be sold.

8. Use Your Pension Effectively

How it works: Most pensions pass outside your estate and are free of IHT. If you die before 75, they're usually income-tax-free to beneficiaries too.

The strategy: If you have other assets, spend those first and preserve your pension as long as possible. Leave your pension to family, and they get it IHT-free.

Check nominations: Make sure your pension death benefits are nominated to the right people. Review after major life changes.

9. Maximise the Residence Nil-Rate Band

How it works: An extra £175,000 allowance applies when you leave your home to direct descendants (children, grandchildren, stepchildren).

The strategy: Make sure your will is set up to benefit from this. Leaving your home to a spouse doesn't qualify (though they get the spouse exemption). Leaving to children does qualify.

Watch for: The allowance reduces if your estate exceeds £2 million. If you're close to this threshold, consider lifetime gifts to get below it.

10. Consider Trusts

How it works: Trusts can remove assets from your estate while you retain some control or provide for different people at different times.

Common IHT trusts:

• Discretionary trusts for grandchildren's education
• Life insurance trusts
• Discounted gift trusts (give assets away while keeping income)
• Loan trusts

Warning: Trust taxation is complex. Putting assets in trust can trigger immediate IHT charges, and trusts have their own ongoing tax rules. Always get professional advice before setting up a trust for IHT purposes.

What Doesn't Work

Gift with reservation: Giving away your house but continuing to live in it rent-free doesn't work. The house remains in your estate.

Deathbed gifts: Gifts made within 7 years of death are still counted. Last-minute planning is of limited value.

Moving abroad: IHT applies to UK domiciled individuals regardless of residence. Changing domicile is complex and usually takes years.

Fake debts: Creating artificial debts to reduce your estate is fraud. Don't do it.

IHT planning works best when started early and done properly. For significant estates, professional advice is essential – the cost of getting it wrong far exceeds the fee for getting it right.
