Inheritance Tax Rules 2025: Essential Insights for UK Property Owners and Expats

The UK’s Inheritance Tax (IHT) rules are evolving in 2025, bringing significant implications for property owners, expats, and high-net-worth individuals. In a recent London Property Podcast episode, Matt Bird, Partner at Sayers Butterworth, unpacked the latest IHT changes, covering thresholds, tax rates, gifts, trusts, and updates for non-UK residents. With a 40% tax rate and new complexities, effective planning is crucial to minimize tax liabilities. Whether you’re managing a London property portfolio, planning your estate, or advising clients, this guide outlines the key IHT rules, common pitfalls, and practical strategies to reduce your tax bill in 2025.

1. IHT Thresholds and the 40% Tax Rate

Understanding IHT thresholds and rates is fundamental for effective estate planning in 2025.

Nil-Rate Band: Each individual has a £325,000 tax-free allowance, with an additional £175,000 residence nil-rate band for homes passed to direct descendants, totaling £500,000 (or £1M for couples combining allowances).

40% Rate: Assets exceeding these thresholds are taxed at 40%. For a £2M London property, this could mean £600,000 in IHT without strategic planning.

Static Thresholds: The 2025 reforms maintain current thresholds, but the inclusion of global assets for long-term residents increases tax exposure for high-net-worth individuals.

Planning Tip: Maximize your nil-rate bands by transferring assets to spouses or civil partners, who inherit tax-free, to reduce the taxable estate.

2. How Gifts and Trusts Are Taxed

The taxation of gifts and trusts under IHT is a critical area, with new rules affecting planning strategies.

Gifts: Gifts made within seven years of death may incur IHT, with tapering relief reducing the tax rate for gifts given 3–7 years prior. Annual exemptions (£3,000 per person) and small gifts (£250 per recipient) remain tax-free.

Trusts: Pre-April 2025 trusts holding non-UK assets for non-domiciled (non-dom) individuals retain IHT exemptions, but new trusts are taxable under the residence-based regime introduced with the non-dom abolition.

Opportunities and Risks: Trusts can protect assets if established early, but improper setup can lead to unexpected tax liabilities, especially for global assets.

Action Step: Leverage annual gifting exemptions and set up trusts before April 2025 to shield non-UK assets, consulting a tax specialist to ensure compliance.

3. Key Updates for Non-UK Residents and Expats

The 2025 IHT reforms significantly impact non-UK residents and expats, particularly following the non-dom status abolition.

Residency-Based IHT: Individuals resident in the UK for 10 out of the last 20 tax years are liable for IHT on worldwide assets at 40%, with liability persisting 3–10 years after leaving the UK, depending on residency duration.

Non-UK Residents: Those owning UK property, such as a London pied-à-terre, are subject to IHT on those assets, with increased scrutiny on global wealth for long-term residents.

Relocation Trends: The reforms are prompting expats to move to tax-friendly jurisdictions like Dubai or Singapore, where IHT is minimal or nonexistent, to avoid the 40% rate.

Expat Strategy: Restructure UK property ownership (e.g., via trusts) or relocate before the 10-year residency threshold to minimize IHT exposure.

4. Common Pitfalls to Avoid

Matt Bird highlights several IHT pitfalls that property owners and investors must steer clear of in 2025:

Delayed Planning: Waiting until after April 2025 risks missing pre-reform trust exemptions and gifting opportunities, increasing tax liabilities.

Outdated Strategies: Pre-2025 plans, such as non-dom trusts, may no longer be effective under the residence-based regime, leading to unexpected taxes.

Ignoring Global Assets: Failing to account for worldwide assets can result in significant IHT bills, especially for expats with international portfolios.

Poor Trust Setup: Incorrectly structured trusts can trigger immediate tax charges or fail to protect assets from IHT.

Investor Insight: Regularly review your estate plan with a tax advisor to align with the latest IHT rules and avoid costly mistakes.

5. Practical Planning Tips to Reduce Your IHT Bill

Proactive IHT planning is essential to minimize tax burdens and secure your legacy. Matt Bird offers these practical tips:

Act Early: Gift assets or establish trusts before April 2025 to leverage exemptions, particularly for non-UK assets held by non-doms.

Use Allowances: Maximize annual gifting exemptions and nil-rate bands to reduce your taxable estate over time.

Diversify Investments: Consider tax-efficient vehicles like Reserved Investor Funds (RIFs), launching March 2025, to balance property investments with lower-tax assets.

Seek Expert Advice: Work with a tax specialist to navigate complex rules, integrate IHT planning with income and capital gains tax strategies, and tailor solutions for London property portfolios.

Expert Advice: Partner with a professional, like Matt Bird, to craft a robust IHT plan that protects your wealth and aligns with your investment goals.
