Life Interest Trust Tax Implications


Understanding Life Interest Trusts and Their Tax Basics in the UK

So, what exactly is a life interest trust, and why should you care about its tax implications? A life interest trust, often called an interest in possession (IIP) trust, is a legal arrangement where one person, the life tenant, gets the right to benefit from the trust’s assets—think income from investments or the right to live in a property—for their lifetime. After they pass, the assets go to other beneficiaries, like children or grandchildren. It’s a popular tool for UK taxpayers and business owners who want to protect assets while ensuring someone, often a spouse, has financial support. But here’s the kicker: the tax rules around these trusts can be a minefield. Let’s break it down with the latest info for the 2025/26 tax year, keeping it practical and clear for you.


What Makes Life Interest Trusts Special?

Now, let’s get to the heart of it. A life interest trust is unique because it splits the benefits of assets between the life tenant (who gets the income or use) and the remaindermen (who get the capital later). For example, imagine Doreen, a 70-year-old widow in Bristol, whose late husband set up a trust in his will. She gets the rental income from a flat in the trust, but when she dies, the flat passes to their kids. This setup is common in wills to provide for a surviving spouse while preserving wealth for the next generation. The tax implications depend on who gets what, when, and how the trust is structured. Let’s dive into the three main taxes: income tax, capital gains tax (CGT), and inheritance tax (IHT).


Income Tax: How It Hits the Trust and You

Let’s talk income tax first, because it’s often the most immediate concern. If you’re a trustee or a life tenant, you need to know who pays what. For the 2025/26 tax year, trusts don’t get a personal allowance, unlike individuals who get £12,570 tax-free (www.gov.uk/check-income-tax-current-year). If the trust’s total income—like interest or dividends—is £500 or less, it’s tax-free, a rule introduced in April 2024 to simplify things for low-income trusts. But if the income tops £500, the trustees pay tax on all income at the basic rate: 20% for most income, 8.75% for dividends.


Here’s where it gets interesting. If the life tenant gets the income directly (mandated to them), the trustees don’t pay tax—the life tenant does, at their personal tax rate. So, if Doreen is a basic rate taxpayer, she pays 20% on the rental income. If she’s a higher rate taxpayer (over £50,270 income), she’ll owe extra via self-assessment. Non-taxpayers like Doreen, if she’s below the personal allowance, can reclaim tax paid by the trustees using form R185. But if the settlor (the person who set up the trust) can benefit, the income is taxed on them, not the life tenant, which can complicate things.

Capital Gains Tax: When Assets Change Hands

Now, consider this: what happens when the trust sells an asset, like Doreen’s flat? Trusts get half the individual CGT annual exemption—£1,500 for 2025/26 (down from £3,000 due to recent cuts). After that, CGT applies at 20% for most assets or 24% for residential property (post-30 October 2024). If Doreen lives in the trust’s property, private residence relief might wipe out CGT on its sale. But here’s a neat trick: when the life tenant dies, the trust assets are revalued for CGT purposes, resetting the base cost to the current market value. No gain, no loss, no tax. This uplift is a big win for trusts set up before 22 March 2006.


Inheritance Tax: The Big One

Be careful! IHT is where life interest trusts can get tricky. For trusts created before 22 March 2006, or immediate post-death interest (IPDI) trusts set up in a will, there’s no 10-yearly charge or exit charge as long as the assets stay in the trust for the life tenant. But if the trust was set up after 22 March 2006 (unless it’s for a disabled person), it falls under the discretionary trust regime, facing a 20% entry charge on assets above the nil rate band (£325,000 in 2025/26), plus periodic and exit charges. If Doreen’s trust ends during her lifetime and assets go to her kids, she’s treated as making a potentially exempt transfer (PET). If she dies within seven years, it’s added to her estate for IHT at 40%.


Why This Matters for You

None of us is a tax expert, but understanding these basics helps you plan. If you’re a business owner like Sanjay, who runs a small café in Leeds and wants to set up a trust for his wife, Priya, you’d use a life interest trust to ensure she gets income from your investments while your kids inherit the capital. The tax-free £500 income threshold is a lifesaver for small trusts, but you’ll need to weigh CGT and IHT implications when selling assets or transferring wealth.






Practical Tax Planning Strategies for Life Interest Trusts

Now, let’s get practical. You’ve got the basics of how life interest trusts are taxed, but how do you make them work for you without tripping over HMRC’s rules? Whether you’re a UK taxpayer setting up a trust or a business owner looking to secure your family’s future, there are clever ways to minimise tax liabilities while keeping things above board. This part dives into actionable strategies, recent tax changes for 2025/26, and real-world scenarios to show you how it’s done. Let’s explore how to make your life interest trust as tax-efficient as possible.


Choosing the Right Assets for Your Trust

So, the question is: what should you put into a life interest trust? The assets you choose can make or break your tax strategy. Cash or income-generating investments like bonds are straightforward—Doreen from our earlier example gets steady income, taxed at her personal rate if mandated. But if you’re a business owner like Sanjay, who owns a chain of cafés in Leeds, you might consider placing business assets into the trust. Why? Business property relief (BPR) can slash IHT by 50% or 100% on qualifying assets like your café’s shares or property, provided they’ve been owned for two years (www.gov.uk/business-relief-inheritance-tax).


Here’s a tip: avoid sticking assets likely to rocket in value, like development land, into a trust unless you’re ready for CGT headaches. When the trust sells, the 24% CGT rate on residential property (or 20% for other assets) can sting, especially with only a £1,500 annual exemption. Instead, opt for assets with stable values or those eligible for reliefs, like Doreen’s rental flat, which qualifies for private residence relief if she lives there.

Timing Your Trust Creation

Now, timing is everything. Setting up a life interest trust during your lifetime (a lifetime trust) versus in your will (an IPDI trust) has different tax implications. Lifetime trusts created after 22 March 2006 face an immediate 20% IHT charge on assets above the £325,000 nil rate band, plus 10-yearly charges of up to 6%. But an IPDI trust, like one set up in Sanjay’s will for Priya, avoids these charges during her lifetime. The catch? The trust’s assets count towards Priya’s estate for IHT when she dies, potentially at 40%.


Here’s a savvy move: if you’re married, use both spouses’ nil rate bands (£650,000 combined in 2025/26) by setting up reciprocal trusts in your wills. For example, Sanjay’s will could leave his café shares to a trust for Priya, using his nil rate band, while Priya’s does the same for Sanjay. This doubles the tax-free amount before IHT kicks in. Just watch out for HMRC’s anti-avoidance rules on mutual benefit trusts—consult a tax pro to get this right.

Maximising Income Tax Efficiency

Let’s not forget income tax. If you’re the life tenant, like Priya receiving dividends from Sanjay’s café shares, you want the income mandated to you directly. Why? Trustees pay tax at flat rates (20% or 8.75%), but you might be a non-taxpayer or basic rate taxpayer, saving you money. For instance, if Priya’s total income is below £12,570, she pays no tax and can reclaim any tax paid by the trustees using form R185 (www.gov.uk/government/publications/trust-and-estate-tax-return).


But what if the trust income pushes you into a higher tax bracket? Here’s a workaround: trustees can accumulate income within the trust (if the deed allows) and distribute it strategically when your personal income is lower, like after retirement. This is especially useful for business owners with fluctuating incomes. Just ensure the trust deed gives trustees this flexibility—check with a solicitor when drafting it.

Capital Gains Tax Hacks

Be careful! CGT can sneak up on you. When a life interest trust sells assets, the £1,500 exemption is puny, so plan disposals carefully. For example, if Sanjay’s trust holds shares in his café business, selling them could trigger a 20% CGT bill. But if the shares qualify for Business Asset Disposal Relief, the rate drops to 10% on lifetime gains up to £1 million (www.gov.uk/entrepreneurs-relief). Another trick: time asset sales after the life tenant’s death. The CGT base cost uplift resets the asset’s value, potentially wiping out gains. For instance, if Doreen’s flat was bought for £200,000 and is worth £500,000 when she dies, the trust’s new base cost is £500,000—no CGT on future sales unless it appreciates further.


Real-Life Scenario: The Patel Family Trust

Now, consider this: Sanjay and Priya, both 55, want to protect their £800,000 café business. Sanjay sets up an IPDI trust in his will, leaving his 50% share (£400,000) to Priya as life tenant, with their kids as remaindermen. The trust generates £20,000 annual dividends, mandated to Priya. She pays 8.75% tax as a basic rate taxpayer, saving money compared to the trust’s rate. When Priya dies, the shares pass to the kids with a CGT uplift, avoiding tax on the £200,000 gain since Sanjay’s death. The trust uses Sanjay’s £325,000 nil rate band, reducing IHT on his estate. Priya’s estate, however, will face IHT on her share unless her own nil rate band and residence nil rate band (£175,000 in 2025/26) apply.


Avoiding Common Pitfalls

None of us wants to mess this up. A big mistake is ignoring trust reporting rules. Since April 2024, all UK trusts must register with HMRC’s Trust Registration Service, even if they owe no tax (www.gov.uk/guidance/register-a-trust-as-a-trustee). Missing this can lead to fines. Another trap: not reviewing the trust deed. If it’s too rigid, trustees can’t adapt to tax changes, like the recent CGT exemption cuts. Work with a tax adviser to ensure your trust is future-proofed for 2025 and beyond.






Advanced Tax Strategies and Tools for Life Interest Trusts

Now, let’s take things up a notch. If you’re a UK taxpayer or business owner with a life interest trust, you’re likely looking for ways to squeeze every bit of tax efficiency out of it. This part dives into advanced strategies, tools, and real-world applications to help you navigate complex estates or business assets. We’ll cover how to leverage tax reliefs, use trust flexibility, and avoid HMRC’s traps, all while keeping things practical for 2025/26. Whether you’re planning for a multi-million-pound estate or a modest family trust, these insights will help you stay ahead.


Leveraging Spousal Exemptions and Reliefs

So, here’s a game-changer: if you’re married or in a civil partnership, the spousal exemption for inheritance tax (IHT) can be your best friend. Transfers between spouses are IHT-free, which is a massive win for life interest trusts set up in wills (IPDI trusts). For example, let’s say Aisha, a 60-year-old business owner in Manchester, sets up an IPDI trust in her will for her husband, Tariq. Her £600,000 estate, including a warehouse used for her catering business, goes into the trust tax-free because it’s a spousal transfer. Tariq gets the income (say, £30,000 a year from rent), and when he dies, the assets pass to their kids. The catch? The warehouse counts towards Tariq’s estate for IHT, but Aisha’s £325,000 nil rate band (and potentially her £175,000 residence nil rate band) can still apply if unused (www.gov.uk/inheritance-tax).


Here’s the pro move: if Aisha’s estate qualifies for Business Property Relief (BPR) at 100%, the warehouse could be IHT-free, even when Tariq dies. BPR applies to business assets used for at least two years, like Aisha’s catering warehouse. Check HMRC’s guidance to confirm eligibility (www.gov.uk/business-relief-inheritance-tax), and document the asset’s business use meticulously to avoid disputes.


Using Trust Flexibility to Manage Income

Now, consider this: not all trusts are rigid. If your trust deed allows, trustees can adjust how income is distributed to dodge higher tax brackets. Take Tariq, who’s a higher rate taxpayer (40% on income over £50,270 in 2025/26). If the trust generates £30,000 in rental income, mandating it to him pushes him into the 40% bracket, costing £12,000 in tax. But if the trustees can accumulate income and distribute it in a year when Tariq’s income is lower (say, post-retirement), he might pay only 20% or nothing if below £12,570. This requires a flexible trust deed—something to discuss with a solicitor when setting up the trust.


Another trick: if the trust holds dividend-paying shares, like Aisha’s catering business shares, trustees can time distributions to align with the life tenant’s tax-free dividend allowance (£500 in 2025/26). If Tariq’s other income is low, he could receive dividends tax-free, saving the trust’s 8.75% rate. Just ensure trustees issue form R185 for any tax credits (www.gov.uk/government/publications/trust-and-estate-tax-return).

Mitigating CGT with Strategic Asset Management

Be careful! Capital Gains Tax (CGT) can erode your trust’s value if you’re not strategic. With only a £1,500 annual exemption for trusts in 2025/26, big asset sales can trigger hefty bills—20% for most assets, 24% for residential property. But here’s a clever tactic: spread sales over multiple tax years to use the exemption annually. For instance, if Aisha’s trust holds £200,000 in investment property, selling it in one go could mean a £47,250 CGT bill (assuming a £50,000 gain). Splitting the sale over two years (£100,000 each) uses two £1,500 exemptions, saving £600 in tax.


Another gem: if the life tenant lives in a trust-owned property, private residence relief can eliminate CGT on its sale. For example, if Tariq lives in the trust’s Manchester flat, selling it for a £100,000 gain incurs no CGT. But if the flat’s rented out, the trust faces the 24% rate. Plan asset use carefully when setting up the trust to maximise reliefs.


Step-by-Step Guide: Setting Up a Tax-Efficient Life Interest Trust

Now, let’s make this actionable. Here’s a step-by-step guide to setting up a life interest trust that minimises tax:

  1. Define Your Goals: Decide who the life tenant (e.g., spouse) and remaindermen (e.g., kids) are. Clarify if you want income or asset use (like living in a property) for the life tenant.

  2. Choose Assets Wisely: Pick assets eligible for reliefs like BPR or private residence relief. Avoid high-growth assets unless you’re prepared for CGT.

  3. Draft a Flexible Trust Deed: Work with a solicitor to ensure trustees can accumulate or mandate income, adapting to tax changes.

  4. Use Spousal Exemptions: If setting up in a will, leverage the IHT spousal exemption to transfer assets tax-free.

  5. Register with HMRC: Use the Trust Registration Service within 90 days of creation, even if no tax is due (www.gov.uk/guidance/register-a-trust-as-a-trustee).

  6. Plan for CGT Uplift: Time asset sales or trust termination after the life tenant’s death to reset the CGT base cost.

  7. Monitor Tax Changes: Stay updated on HMRC rules, like the £500 trust income exemption or CGT rate hikes, via www.gov.uk.


    This guide ensures your trust is tax-efficient from day one, but always consult a tax adviser for bespoke advice.

Real-Life Scenario: The Khan Family Trust

Here’s a case from 2024: Meera, a 65-year-old retiree in Birmingham, inherited a life interest trust from her mother’s will, holding a £400,000 rental property and £100,000 in bonds. The trust generates £15,000 annual rental income, mandated to Meera. As a basic rate taxpayer, she pays 20% (£3,000) on the income, reclaiming tax via R185 since her total income is below £12,570. When the property is sold in 2025, the trust uses its £1,500 CGT exemption, paying 24% on the £80,000 gain (£18,600 tax). Meera’s trustees plan to sell half the bonds in 2026 to use another exemption, saving £300 in CGT. When Meera dies, the trust’s assets get a CGT uplift, and her kids inherit with no immediate IHT thanks to her unused nil rate band.


Avoiding HMRC Scrutiny

None of us wants a letter from HMRC. A common pitfall is underreporting income or gains. Trustees must file a Trust and Estate Tax Return (SA900) annually if there’s taxable income or gains, even with the £500 income exemption. Another trap: assuming all trusts qualify for spousal exemptions. If Aisha sets up a lifetime trust for Tariq and retains an interest (e.g., can benefit from it), HMRC taxes her as if she still owns the assets. Always clarify the settlor’s role with a tax pro to avoid this.

How a Tax Accountant Can Help with Life Interest Trust Tax Management

Now, let’s talk about getting expert help. Managing a life interest trust’s tax implications can feel like navigating a maze blindfolded, especially if you’re a UK taxpayer or business owner juggling multiple responsibilities. A skilled tax accountant, like those at My Tax Accountant (https://www.mytaxaccountant.co.uk/), can be your guide, ensuring your trust is tax-efficient and compliant with HMRC’s rules for 2025/26. This part dives into how professionals can save you time, money, and stress, with a detailed case study showing their impact in action. Plus, we’ll invite you to reach out to My Tax Accountant’s CEO, Mr. Maz, for a free consultation to tackle your trust’s tax challenges.


Why You Need a Tax Accountant for Your Trust

So, why can’t you just DIY this? Life interest trusts involve complex interplay between income tax, capital gains tax (CGT), and inheritance tax (IHT), with rules that shift—like the recent CGT exemption cut to £1,500 for trusts in 2025/26. A tax accountant doesn’t just crunch numbers; they strategise. They’ll review your trust deed, spot tax-saving opportunities (like Business Property Relief), and ensure you’re not overpaying HMRC. For instance, if you’re a business owner like Sanjay from our earlier examples, an accountant can confirm whether your café’s assets qualify for 100% IHT relief, potentially saving £400,000 on a £1 million estate.


Accountants also handle HMRC compliance, like registering your trust on the Trust Registration Service (www.gov.uk/guidance/register-a-trust-as-a-trustee) or filing the SA900 tax return. Miss these, and you’re looking at fines or audits. Plus, they can liaise with HMRC on your behalf, saving you from those dreaded tax office calls.


Trust Management Hierarchy - How a Tax Accountant Can Help for Your Trust

Trust Management Hierarchy

Tailoring Your Trust for Maximum Efficiency

Here’s the deal: every trust is unique. A tax accountant customises your strategy based on your goals. Are you, like Doreen, a life tenant relying on trust income? An accountant can ensure income is mandated to you at your personal tax rate, potentially reclaiming tax via form R185 if you’re a non-taxpayer (www.gov.uk/government/publications/trust-and-estate-tax-return). Or, if you’re a trustee managing assets for multiple beneficiaries, they’ll advise on timing distributions to minimise tax, like holding income until a low-tax year. For business owners, they’ll align your trust with reliefs like Business Asset Disposal Relief, cutting CGT to 10% on qualifying sales up to £1 million (www.gov.uk/entrepreneurs-relief).


Case Study: The Choudhury Family Trust

Now, let’s see this in action with a real-world case from 2024, handled by My Tax Accountant. Meet Rina Choudhury, a 62-year-old widow in London, who inherited a life interest trust from her late husband, Arjun, who owned a chain of three convenience stores valued at £1.2 million, plus £200,000 in investment bonds. The trust, set up as an IPDI in Arjun’s will, named Rina as the life tenant, receiving £40,000 annual income from store rents and bond interest, with their two children, Anika and Rohan, as remaindermen. Here’s how My Tax Accountant, led by Mr. Maz, turned this complex trust into a tax-efficient powerhouse:

  1. Income Tax Optimisation: Rina’s personal income was £10,000 from a pension, keeping her below the £12,570 personal allowance for 2024/25. The trust’s £40,000 income (£30,000 rent, £10,000 bond interest) was mandated to her, but trustees had paid 20% tax (£8,000). Mr. Maz filed form R185, reclaiming the full £8,000 since Rina was a non-taxpayer, boosting her net income. He also advised trustees to mandate future income directly, avoiding unnecessary tax.

  2. CGT Planning: In 2024, the trustees wanted to sell one store for £400,000, with a £100,000 gain. The trust’s £1,500 CGT exemption left a £98,500 taxable gain at 20% (£19,700 tax). Mr. Maz suggested splitting the sale across two tax years (2024/25 and 2025/26), using two £1,500 exemptions to save £600. He also confirmed the remaining stores qualified for Business Property Relief, ensuring no IHT on their value.

  3. IHT Strategy: Arjun’s estate used his £325,000 nil rate band, and the spousal exemption covered the rest. When Rina dies, her estate will include the trust’s £1.4 million value, but Mr. Maz identified that her unused £325,000 nil rate band and £175,000 residence nil rate band (transferable from Arjun) could reduce IHT. He also ensured the stores’ BPR eligibility was documented, potentially wiping out IHT on £1.2 million.

  4. Compliance and Reporting: The trust wasn’t registered with HMRC’s Trust Registration Service, risking a £5,000 fine. Mr. Maz completed registration within 90 days and filed the SA900 return, reporting the £40,000 income and £100,000 gain, ensuring full compliance.

  5. Future-Proofing: With CGT rates rising to 24% for property in October 2024, Mr. Maz advised retaining the stores until Rina’s death for a CGT base cost uplift, resetting their value to £1.2 million and avoiding tax on prior gains. He also recommended amending the trust deed to allow income accumulation, giving trustees flexibility if Rina’s tax status changes.

Summary of All the Most Important Points

  • A life interest trust allows a life tenant to benefit from assets (e.g., income or property use) during their lifetime, with assets passing to remaindermen afterward, but tax rules vary based on setup and timing.

  • Trusts pay income tax at 20% for most income and 8.75% for dividends if income exceeds £500, but life tenants pay at their personal rate if income is mandated to them, potentially reclaiming tax via form R185.

  • Trusts receive a £1,500 CGT annual exemption in 2025/26, with gains taxed at 20% (or 24% for residential property), but a CGT base cost uplift at the life tenant’s death can eliminate gains.

  • IPDI trusts set up in wills avoid IHT entry, periodic, and exit charges, but assets count toward the life tenant’s estate for IHT at 40% upon their death.

  • Lifetime trusts post-22 March 2006 face a 20% IHT entry charge on assets above £325,000, plus up to 6% periodic and exit charges, unlike IPDI trusts.

  • Business Property Relief (BPR) can reduce IHT by 50% or 100% on qualifying business assets like shares or property held for two years, ideal for business owners.

  • Spousal exemptions allow IHT-free transfers to a spouse’s life interest trust, and using both spouses’ £325,000 nil rate bands can double tax-free allowances.

  • Trustees can accumulate income (if the trust deed allows) to distribute in low-tax years, minimising income tax for life tenants in higher tax brackets.

  • Splitting asset sales over multiple tax years maximises use of the £1,500 CGT exemption, while private residence relief can eliminate CGT on a trust-owned home used by the life tenant.

  • All UK trusts must register with HMRC’s Trust Registration Service, even if no tax is due, to avoid fines, and trustees must file SA900 returns for taxable income or gains.




A Very Comprehensive Guide for Life Interest Trust Tax Implications





FAQs

1. Q: Can you set up a life interest trust for someone other than a spouse or civil partner?

A: Yes, you can set up a life interest trust for anyone, such as a child or sibling, but spousal exemptions for inheritance tax won’t apply, potentially increasing tax liabilities.


2. Q: How does a life interest trust affect your eligibility for means-tested benefits?

A: The income from a life interest trust is counted as your income for means-tested benefits like Universal Credit, potentially reducing or eliminating your eligibility.


3. Q: Can you terminate a life interest trust early?

A: Yes, with agreement from all beneficiaries and trustees, or if the trust deed allows, but early termination may trigger inheritance tax or capital gains tax events.


4. Q: What happens to a life interest trust if the life tenant remarries?

A: Remarriage doesn’t automatically affect the trust, but if the trust’s assets are included in the life tenant’s estate, it could impact inheritance tax planning for the new spouse.


5. Q: Can a life interest trust hold foreign assets?

A: Yes, but foreign assets may face additional tax obligations in the UK and abroad, requiring careful reporting to HMRC to avoid double taxation.


6. Q: How does a life interest trust affect your pension planning?

A: Trust income counts toward your taxable income, which could push you into a higher tax bracket, affecting pension contribution limits or tax relief eligibility.


7. Q: Can you add assets to an existing life interest trust?

A: Yes, if the trust deed permits, but adding assets may trigger an immediate 20% inheritance tax charge if the value exceeds the £325,000 nil rate band in 2025/26.


8. Q: Are life interest trusts protected from creditors?

A: Generally, trust assets are protected from the life tenant’s creditors, but if you’re the settlor and retain benefits, creditors may pursue the assets.


9. Q: Can a life interest trust be used to protect assets from care home fees?

A: Setting up a trust to avoid care home fees can be challenged by local authorities if deemed deliberate deprivation of assets, so consult a legal expert first.


10. Q: What records must trustees keep for a life interest trust?

A: Trustees must maintain records of all income, gains, distributions, and expenses for at least six years to comply with HMRC audits and reporting requirements.


11. Q: Can you change the life tenant of a life interest trust?

A: No, the life tenant is typically fixed in the trust deed, but with legal advice, the trust could be terminated or varied, potentially triggering tax consequences.


12. Q: How does a life interest trust impact your tax return obligations?

A: If you’re a life tenant receiving mandated income, you must report it on your self-assessment tax return, while trustees file a separate SA900 trust return.


13. Q: Can a life interest trust own a business outright?

A: Yes, a trust can own a business, but managing it requires active trustee involvement, and business assets may qualify for Business Property Relief to reduce IHT.


14. Q: What happens if a life interest trust becomes insolvent?

A: If trust expenses exceed income or assets, trustees may need to sell assets, but beneficiaries aren’t personally liable unless they’ve received overpayments.


15. Q: Can you use a life interest trust to gift assets to charity?

A: Yes, a trust can designate a charity as a remainderman, potentially qualifying for IHT charitable exemptions if structured correctly.


16. Q: How does a life interest trust affect your residence nil rate band?

A: If the trust includes your home and passes to direct descendants, the £175,000 residence nil rate band may still apply, but only if the trust ends on your death.


17. Q: Can a life interest trust be challenged in court?

A: Yes, beneficiaries or creditors can challenge a trust for reasons like fraud or undue influence, but courts rarely overturn validly created trusts without strong evidence.


18. Q: What are the costs of setting up a life interest trust?

A: Costs vary, typically £1,000–£5,000 for legal and tax advice, plus ongoing trustee fees, depending on the trust’s complexity and asset value.


19. Q: Can you use a life interest trust to manage assets for a minor?

A: Yes, but the minor can’t be the life tenant; instead, the trust can hold assets until they reach adulthood, with income managed by trustees.


20. Q: How does a life interest trust affect your eligibility for tax credits?
