Inheritance Tax Planning 2025: Latest Allowances and Reliefs

Published on 
22 Aug 2025

Inheritance tax can take a significant portion of your estate if you don’t plan carefully. For 2025, there are key allowances and reliefs that you should know about to reduce the tax your beneficiaries might pay. Understanding these thresholds and reliefs helps you protect more of your assets for the people you care about.

You can take advantage of tax-free gifts, business relief, and other exemptions to lower the amount of inheritance tax owed. These options allow you to pass on more wealth without unnecessary tax charges, especially as property values rise and estates grow larger. Knowing how to use these tools effectively is essential.

Your estate planning will benefit from being structured around the latest rules for 2025. By reassessing your eligibility for reliefs like Business and Agricultural Relief and maximising available allowances, you can create a strategy that reduces the overall tax bill. This guide will explain the most important updates and how they might affect you.

Key Inheritance Tax Allowances for 2025

You need to understand the specific allowances and thresholds to manage your estate efficiently. These allowances determine how much of your estate can pass tax-free, who qualifies for exemptions, and how frozen thresholds might affect your tax bill.

Nil-Rate Band and Thresholds

The nil-rate band (NRB) allows you to pass on up to £325,000 of your estate without paying inheritance tax (IHT). This threshold has been frozen until 5 April 2030, meaning it will not increase with inflation or rising property values.

Any estate value above £325,000 is taxed at 40%. This tax rate applies to the portion of the estate that exceeds the NRB. It’s important to plan to fully use this allowance to reduce your future IHT liability.

You can also transfer any unused portion of your NRB to your spouse or civil partner, effectively doubling the allowance to £650,000 for couples.

Main Residence Nil-Rate Band

In addition to the NRB, the main residence nil-rate band (RNRB) offers an extra allowance when you pass your primary home to direct descendants, such as children or grandchildren.

For 2025, the RNRB is set at £175,000. This allowance is also frozen until April 2030. When combined with the standard NRB, you could pass on up to £500,000 tax-free if your estate includes your main home.

The RNRB tapers away for estates valued above £2 million, so it’s important to check if this reduction applies to your estate.

Spouse and Charity Exemptions

Transfers between spouses or civil partners are exempt from IHT, regardless of the amount. This means you can leave any value to your spouse without triggering a tax bill.

Charitable donations made in your will also qualify for exemptions, reducing your overall estate value subject to IHT. The donation must be at least 10% of the net estate to qualify for a reduced IHT rate of 36%.

Using these exemptions can save significant tax for your beneficiaries and support causes important to you.

Implications of Frozen Allowances

Because the nil-rate band and residence nil-rate band are frozen until 2030, inflation and rising property prices could push more estates over the tax-free thresholds. This may increase your IHT liability, even if your estate value hasn’t changed much in real terms.

You should review your estate plans regularly to ensure they remain tax-efficient under these frozen thresholds. Consider steps like gifts during your lifetime or trusts to reduce the amount potentially subject to IHT.

Working with an HMRC-compliant adviser can help you adapt to these fixed limits and use allowances and reliefs effectively.

Latest Inheritance Tax Reliefs and Exemptions

You have several ways to reduce the amount of inheritance tax (IHT) your estate might owe. These include using specific gifting rules, exemptions based on how long ago you made gifts, reliefs for business and farm assets, and allowances for regular payments from your income.

Gifting Rules and Annual Exemptions

You can give away up to £3,000 each tax year without it being added to the value of your estate for IHT. This is known as the annual exemption. If you didn’t use this allowance last year, you can carry it forward for one year only.

Small gifts of up to £250 per person each tax year are also exempt, but this doesn’t apply if you use another exemption for the same recipient. Gifts made for weddings or civil partnerships have fixed limits depending on your relation to the recipient.

Be aware that large gifts could trigger capital gains tax (CGT) if the asset has increased in value. Always consider both IHT and CGT when planning gifts.

The Seven-Year Rule: Potentially Exempt Transfers

When you make gifts over the annual exemption limit, they become potentially exempt transfers (PETs). If you live for seven years after making the gift, the gift is exempt from IHT.

If you pass away within seven years, the gift’s value is added to your estate. The tax rate may reduce gradually, depending on how long after the gift you die. This is known as taper relief.

Keep in mind that HMRC monitors these transfers closely, so accurate records of dates and values are essential. This rule lets you reduce your estate’s taxable value but requires careful timing.

Reliefs for Agricultural and Business Property

Certain business and agricultural assets get IHT relief to encourage investment and continuity. Business Property Relief (BPR) can reduce IHT by 50% or 100% on qualifying assets like unquoted shares or active businesses you have owned for at least two years.

Agricultural Property Relief (APR) applies to farmland you or a tenant have worked for a set period before death. Relief rates are either 50% or 100%, depending on circumstances.

From April 2026, the total relief you can claim on BPR and APR assets will be capped at £1 million at 100%, with any excess receiving only 50%. Also, BPR on AIM-listed shares will drop to 50%.

These reliefs can save you significant tax but need careful planning, especially with upcoming changes.

Normal Expenditure from Income

You can make regular payments out of your income to someone without those payments being added to your estate for IHT, provided they do not affect your standard of living.

This typically applies to regular gifts such as maintenance payments for family members or donations to charities.

It is important that you have enough income left after these payments and that the payments are habitual and consistent.

This relief offers a tax benefit by allowing you to reduce your estate’s value without using your lifetime gift allowances. You must keep clear records and evidence of your income and payments.

Inheritance Tax Planning Strategies for 2025

Effective planning can help you reduce your inheritance tax (IHT) burden in 2025. You need to consider how lifetime gifts, trusts, and residency status affect your estate. Using these tools wisely can optimise your estate’s value and protect your wealth for future generations.

Lifetime Gifts Versus Bequests

Making gifts during your lifetime is one of the most effective ways to reduce your estate’s IHT liability. Gifts you give more than seven years before your death are usually exempt from IHT. This is known as the seven-year rule.

You can also make use of annual gift allowances, such as the £3,000 annual exemption and small gift exemptions of up to £250 per person. These let you give money or assets each year without decreasing your nil-rate band.

Bequests through your will, however, are subject to IHT immediately upon death, unless they qualify for exemptions or reliefs. Planning any lifetime gifts carefully ensures you don’t lose access to essential assets while also lowering potential IHT.

Trusts and Wealth Protection

Trusts are valuable tools to protect your assets and reduce inheritance tax exposure. Placing assets in a trust removes them from your estate, which may lower your IHT liability at death.

Common types of trusts include bare trusts, interest in possession trusts, and discretionary trusts. Each offers different levels of control and tax advantages. For example, discretionary trusts give trustees flexibility to distribute assets but can carry a ten-year IHT charge.

You should work closely with a tax advisor or estate planning professional to decide the right trust type. Properly set up trusts can pass wealth safely while potentially avoiding or reducing estate taxes.

Estate Planning for Non-Domiciled Individuals

Non-domiciled residents face more complex IHT rules in 2025. If you are non-domiciled but deemed UK resident for IHT, your worldwide assets could be liable for inheritance tax.

However, certain election options let you limit IHT to only UK assets by paying an annual charge. Careful estate planning can help you weigh this option against full exposure.

You should review your residence and domicile status regularly, especially if you have moving plans. A specialist tax advisor can guide you on exemptions, reliefs, and the best course to protect your estate under the 2025 rules.

Integration with Broader Tax Changes

Inheritance tax reforms in 2025 come alongside other important tax changes that affect how you manage your wealth. These include adjustments to capital gains tax, ongoing developments from tax authorities like HMRC and the IRS, and the need to align inheritance tax planning with your broader personal and business tax strategy.

Interplay with Capital Gains Tax

Capital Gains Tax (CGT) often intersects with inheritance tax (IHT) planning, especially when you transfer assets like property or shares. For example, when you pass assets on death, CGT is usually not charged because of the "base cost uplift," which resets the value for gains calculation. However, if you gift assets during your lifetime, CGT may apply immediately on any gains made since acquisition.

You should be aware that changes to IHT, such as new relief limits, may affect decisions about whether to hold or sell assets. Coordinating CGT and IHT planning can help reduce your overall tax burden, especially when considering lifetime gifts versus transfers on death. Consulting tax rules on reliefs for business and agricultural property is also key, as they impact both CGT and IHT outcomes.

Impact of IRS and HMRC Developments

Recent updates from tax authorities like HMRC in the UK and the IRS in the US affect how you plan your estate, especially if you have cross-border assets or interests. The UK’s shift from domicile-based to residence-based IHT means long-term UK residents could now face IHT on worldwide assets, increasing complexity.

HMRC’s new rules on unused pension funds from 2027 bring pensions into play for IHT, changing your planning options. Meanwhile, the IRS continues to update reporting requirements and tax treaty provisions that could affect your US-linked assets and trusts. Staying informed about these changes will help you avoid surprises and ensure compliance with both UK and US tax obligations.

Coordinating With Personal and Business Tax Planning

Your inheritance tax planning must fit with your wider tax strategy, both personally and for any business interests. For businesses, the £1 million combined cap on Agricultural Property Relief (APR) and Business Property Relief (BPR) from 2026 alters how much relief you can claim on business assets. This limits relief scope and means you need to reconsider succession plans carefully.

On a personal level, aligning your IHT planning with PAYE codes, pension contributions, and gifting strategies can maximise tax efficiency. Regular reviews of your tax code, allowances, and reliefs ensure you don’t miss opportunities. Using trusts, charitable giving, and other tax planning tools in concert with these business and personal tax factors is essential to protect your estate and reduce liabilities.

Professional Guidance and Compliance Considerations

Managing inheritance tax correctly requires careful attention to legal rules and deadlines. Knowing how to work with experts and keep accurate records can help you avoid costly errors and ensure compliance with HMRC regulations.

Choosing a Qualified Tax Advisor

You should select a tax advisor who specialises in inheritance tax and understands the latest 2025 changes. Look for professionals with recognised qualifications, such as Chartered Tax Adviser (CTA) status or membership in reputable bodies like the Chartered Institute of Taxation.

A good advisor will explain complex rules clearly, help you identify available reliefs, and design a tax plan that suits your situation. They can also represent you in dealing with HMRC, making the process smoother and reducing the risk of mistakes.

Avoid advisors who promise unrealistic tax savings or fail to provide transparent fees. Always check references or reviews to ensure their advice is reliable and compliance-focused.

Importance of Record Keeping

Keeping detailed records is essential when managing inheritance tax. You need clear documentation of all asset values, gifts, trusts, and relevant transactions over your lifetime to support any claims for relief or exemptions.

Organise paperwork such as wills, property deeds, and financial statements promptly. Accurate records help you meet HMRC’s reporting requirements and make it easier for your personal representatives to complete tax returns after your death.

Without proper records, you risk delays, penalties, or missing out on tax reliefs you are entitled to. Use spreadsheets or digital tools to track important dates and asset values each year.

Common Mistakes to Avoid

Failing to update your tax plan after legislative changes is a common error. The 2025 reforms mean some reliefs and allowances, such as Agricultural and Business Property Relief, now have limits you must factor in.

Do not assume all gifts are automatically exempt. Certain lifetime transfers may trigger immediate or future inheritance tax charges if not handled correctly.

Another frequent mistake is underestimating the impact of unused pension funds now included in estates from 2027. Ignoring these can lead to unexpected tax bills.

Always submit timely and accurate returns to HMRC. Missing deadlines or providing incomplete information can result in interest charges or fines, complicating your estate planning efforts.
