Inheritance Tax Thresholds 2026: What You Need to Know

Inheritance Tax Thresholds 2026: What You Need to Know

Inheritance Tax (IHT) can significantly impact what your loved ones inherit from your estate. Understanding the 2026 thresholds and allowances helps you plan effectively and potentially reduce the tax burden on your family.

Here's everything you need to know about UK inheritance tax rates and thresholds for 2026.

Current Inheritance Tax Rates (2026)

Inheritance tax is charged at 40% on the value of your estate above the tax-free threshold. However, if you leave at least 10% of your estate to charity, the rate reduces to 36% on the taxable portion.

The key question is: what counts as "tax-free"?

The Nil-Rate Band: £325,000

The main inheritance tax threshold is called the "nil-rate band." For 2026, this remains at £325,000. This means:

• The first £325,000 of your estate is tax-free
• Everything above this amount is taxed at 40% (or 36% with charitable giving)

This threshold has been frozen at £325,000 since 2009, despite inflation increasing the value of many people's homes and savings.

Example: Basic IHT Calculation

If your estate is worth £525,000:

• Tax-free: £325,000
• Taxable amount: £200,000
• Tax due: £200,000 × 40% = £80,000

Residence Nil-Rate Band: Additional £175,000

If you're leaving your main home to direct descendants (children, grandchildren, or their spouses), you may qualify for an additional allowance called the "residence nil-rate band."

For 2026, this adds up to £175,000 to your tax-free threshold, but only if:

1. You own your main residence (or owned one and downsized/sold it after July 2015)
2. You're leaving it to direct descendants (not siblings, nephews, nieces, or friends)
3. Your total estate is under £2 million (the allowance reduces above this)

Combined Allowances

If you qualify for both allowances:

• Nil-rate band: £325,000
• Residence nil-rate band: £175,000
• Total tax-free: £500,000

Example: Home to Children

Estate worth £650,000, including £400,000 family home left to children:

• Tax-free: £500,000 (£325,000 + £175,000)
• Taxable amount: £150,000
• Tax due: £150,000 × 40% = £60,000

Married Couples and Civil Partnerships

Spouses and civil partners can combine their allowances, potentially doubling the tax-free amount.

Transfers Between Spouses

• No inheritance tax applies on transfers between spouses/civil partners (if both are UK domiciled)
• This allows the first spouse to die to pass everything to the survivor tax-free

Transferring Unused Allowances

When the first spouse dies, any unused nil-rate band and residence nil-rate band can transfer to the surviving spouse.

This means the surviving spouse could have:

• Own nil-rate band: £325,000
• Transferred nil-rate band: £325,000
• Own residence nil-rate band: £175,000
• Transferred residence nil-rate band: £175,000
• Total potential tax-free: £1,000,000

Example: Married Couple Planning

First spouse dies, leaves everything to surviving spouse:

• No tax due (spouse exemption)
• 100% of both allowances transfer to survivor

Surviving spouse later dies with £900,000 estate:

• Tax-free: £1,000,000 (combined allowances)
• Tax due: £0

The £2 Million Taper

The residence nil-rate band reduces if your estate exceeds £2 million. For every £2 above the £2 million threshold, the residence allowance reduces by £1.

Taper Calculation

Estate value: £2,100,000

• Excess over £2m: £100,000
• Reduction: £100,000 ÷ 2 = £50,000
• Available residence nil-rate band: £175,000 - £50,000 = £125,000

This means very wealthy estates may lose the residence allowance entirely.

What Counts Towards Your Estate?

Your estate for inheritance tax purposes includes:

Included Assets

• Property — Your home and any other properties
• Savings and investments — Bank accounts, ISAs, shares, bonds
• Personal possessions — Cars, jewellery, art, collectibles
• Business assets — Shares in companies you own
• Life insurance — If paid to your estate (not directly to beneficiaries)
• Gifts made in the 7 years before death — May be added back

Excluded Items

• Spouse/civil partner inheritance — If they're UK domiciled
• Charitable donations — Gifts to registered charities
• Political donations — Gifts to qualifying political parties
• Some business property — May qualify for business property relief
• Agricultural land — May qualify for agricultural property relief

Debt and Funeral Costs

You can deduct certain costs from your estate:

• Outstanding mortgages and loans
• Credit card and personal debt
• Reasonable funeral costs (typically £5,000-£10,000)
• Professional fees for administering the estate

Example: Estate with Debts

Total assets: £600,000 Outstanding mortgage: £150,000 Funeral costs: £8,000 Net estate: £600,000 - £150,000 - £8,000 = £442,000

Tax calculation on £442,000 (not the gross £600,000).

Gifts and the 7-Year Rule

Gifts made during your lifetime can affect inheritance tax:

Annual Exemptions

Each year you can give away:

• £3,000 annual exemption (can carry forward unused amount for one year)
• £250 to any number of different people
• Wedding gifts: £5,000 to children, £2,500 to grandchildren, £1,000 to others
• Regular gifts from income — if they don't affect your standard of living

Potentially Exempt Transfers (PETs)

Larger gifts become "potentially exempt transfers":

• Tax-free if you survive 7 years after making the gift
• May be taxed if you die within 7 years, but with taper relief

Taper Relief on Gifts

If you die 3-7 years after making a gift:

• Years 0-3: 40% tax
• Years 3-4: 32% tax
• Years 4-5: 24% tax
• Years 5-6: 16% tax
• Years 6-7: 8% tax
• Years 7+: 0% tax

Planning Strategies to Reduce IHT

1. Use Annual Exemptions

Make regular use of the £3,000 annual exemption and other small gift allowances. Over time, this can remove significant value from your estate.

2. Consider Lifetime Giving

If you can afford it, make larger gifts and hope to survive the 7-year period. Even if you don't, taper relief may reduce the tax.

3. Charity Giving

Leaving 10% or more to charity reduces the inheritance tax rate from 40% to 36% on the taxable portion.

4. Trust Planning

Certain trust structures can help manage inheritance tax, but these are complex and require professional advice.

5. Life Insurance

Life insurance written in trust can provide funds to pay inheritance tax without increasing your estate value.

6. Pension Planning

Pensions often sit outside your estate for inheritance tax purposes, making them tax-efficient wealth transfer vehicles.

When Is IHT Due?

Inheritance tax must usually be paid within 6 months of death. Some assets (like property) can have tax paid in instalments over 10 years, but interest applies.

Executors are personally liable for ensuring IHT is paid, making professional advice important for larger estates.

Business and Agricultural Relief

Some business assets and agricultural land qualify for significant inheritance tax reliefs:

Business Property Relief (BPR)

• 100% relief on unquoted trading company shares
• 50% relief on some other business assets
• The business must be trading (not just investment holding)

Agricultural Property Relief (APR)

• 100% relief on agricultural land and buildings
• Must be used for agricultural purposes
• Various ownership and occupancy requirements apply

Record Keeping

Keep detailed records of:

• Annual gifts and who received them
• Asset valuations and supporting evidence
• Purchase receipts for valuable items
• Professional valuations for property and businesses

Good records make estate administration much smoother for your executors.

Getting Professional Help

Consider professional advice if:

• Your estate may exceed £325,000 (or £1m for married couples)
• You own business assets or agricultural land
• You want to make significant lifetime gifts
• You're considering trust arrangements
• Your affairs are complex (multiple properties, overseas assets, etc.)

Key Changes to Watch

Inheritance tax rules can change with new governments. Recent discussions have included:

• Reducing the nil-rate band
• Changing spouse/civil partner exemptions
• Modifying business and agricultural reliefs
• Altering the residence nil-rate band

Stay informed about potential changes, especially if you're actively planning your estate.
