Understanding Limited Company Inheritance Tax and How to Verify Your Position
Picture this: You’re a business owner, maybe running a family firm in Birmingham or a tech startup in London, and you’re wondering what happens to your limited company when you pass away. Inheritance Tax (IHT) can feel like a dark cloud over your legacy, but it doesn’t have to be. In my 15 years advising UK taxpayers, I’ve seen countless business owners navigate this with smart planning, saving thousands in tax. This article dives deep into IHT for limited companies, offering practical steps to verify and calculate your liability, tailored for UK taxpayers and business owners in 2025. Let’s start with the essentials, then build to actionable strategies, including worksheets to make it crystal clear.
What Is Inheritance Tax for Limited Companies?
IHT is a tax on the estate of someone who’s passed away, charged at 40% on assets above the £325,000 nil-rate band (NRB) for the 2025/26 tax year. For limited companies, IHT applies to the value of shares you own in the company when you die. Unlike personal assets, company shares can qualify for Business Relief (BR), which can reduce or eliminate IHT if the company is a trading business and you’ve held the shares for at least two years. According to HMRC’s 2025 guidance, BR can cut IHT by 100% for qualifying trading companies or 50% for certain assets like land used in the business. But, as I’ve seen with clients, it’s not automatic – you need to plan carefully.
The catch? Not all companies qualify. Investment companies, like those holding buy-to-let properties, often don’t get BR, leaving shares fully taxable. And with the Autumn 2024 Budget capping 100% BR at £1 million from April 2026, anything above that gets only 50% relief, meaning a 20% effective IHT rate on excess value. For example, if your company’s shares are worth £1.5 million, £1 million gets full relief, but the remaining £500,000 faces £100,000 in IHT (20% of £500,000). This change, announced by Chancellor Rachel Reeves, has sparked concern among family businesses, and I’ve had clients scrambling to reassess their plans.
2025/26 IHT Thresholds and Rates | Details |
Nil-Rate Band (NRB) | £325,000 per person; transferable to spouse/civil partner, up to £650,000 for couples. |
Residence Nil-Rate Band (RNRB) | £175,000 per person if passing main home to direct descendants; tapers above £2m estate. |
IHT Rate | 40% on taxable estate above NRB/RNRB; 36% if 10%+ of estate goes to charity. |
Business Relief (BR) | 100% on qualifying trading company shares (held 2+ years); 50% on excess above £1m from April 2026. |
Why Does IHT Matter for Your Limited Company?
None of us loves tax surprises, but IHT can hit hard if you don’t plan. In 2023/24, HMRC collected £7.5 billion in IHT, with business owners often caught out by assuming BR covers everything. If your company’s shares are worth £2 million and don’t qualify for BR, your estate could face an £800,000 tax bill (40% of £2m minus £325,000 NRB). Even with BR, the new £1 million cap means planning is critical. I’ve seen clients in London devastated when their property investment company didn’t qualify, leaving heirs with hefty bills. Verifying your company’s status and calculating potential IHT now can save your family from chaos later.
Step-by-Step: Verify Your Company’s IHT Status
Let’s get practical. To check if your limited company shares qualify for BR and estimate your IHT exposure, follow these steps:
Confirm Trading Status: Check if your company is a trading business (e.g., manufacturing, retail) rather than an investment one (e.g., holding rental properties). HMRC defines trading as actively providing goods or services. For example, a client running a catering company qualified for 100% BR, but another with a property portfolio didn’t.
Assess Share Ownership: Have you held the shares for at least two years? If not, BR won’t apply. Check your company’s incorporation date and share register.
Value the Shares: Get a professional valuation of your company’s shares, considering assets, profits, and market conditions. For instance, a tech startup might be valued at £1.2 million based on revenue multiples.
Check for Exclusions: Shares in companies listed on main stock exchanges (not AIM) don’t qualify for BR. Also, ensure shareholder agreements don’t restrict BR eligibility, as I’ve seen with poorly drafted contracts.
Log into Your Personal Tax Account: Visit www.gov.uk/check-income-tax-current-year to review your tax position, including any lifetime gifts that could affect your NRB.
Case Study: Sarah’s Catering Company
Take Sarah, a Manchester-based caterer I advised in 2024. Her limited company was worth £1.8 million, with shares she’d held for five years. She assumed BR would wipe out IHT, but the new £1 million cap meant £800,000 was taxable at 20% from April 2026, potentially costing £160,000. We restructured her shareholding, gifting some to a discretionary trust, which I’ll cover in Part 2. This slashed her IHT liability while keeping control. Sarah’s story shows why verifying your position early is crucial.
Common Pitfalls to Avoid
Be careful here, because I’ve seen clients trip up when they assume all companies qualify for BR. Investment companies, like those holding shares or properties, often face full IHT. Another trap is selling shares before death – the cash becomes taxable, losing BR. For example, a client sold his trading company for £1.5 million, turning tax-free shares into a taxable lump sum, costing his estate £400,000 in IHT. Always consult a tax adviser before major transactions.

Calculating and Optimising Your Limited Company IHT Liability
So, you’ve got a handle on whether your limited company qualifies for Business Relief (BR) and the basics of Inheritance Tax (IHT). Now, let’s roll up our sleeves and dive into the nitty-gritty of calculating your IHT liability, especially if you’ve got multiple income sources or operate in Scotland or Wales. In my years advising clients across the UK, I’ve seen how easy it is to miscalculate IHT or miss optimisation opportunities. This part gives you practical tools, including a custom calculation template, to verify your liability and spot savings, tailored for business owners and taxpayers in 2025.
How Do You Calculate IHT for Your Company Shares?
None of us loves number-crunching, but calculating IHT is simpler than it sounds. Your limited company’s shares form part of your estate, and their value, minus any BR or allowances, determines your tax bill. Here’s a step-by-step guide to get it right:
Determine Share Value: Get a professional valuation, factoring in company assets, profits, and market conditions. For example, a retail business might be valued at £2 million based on a 5x profit multiple.
Apply Business Relief: If eligible, deduct 100% of the share value up to £1 million (post-April 2026, per HMRC’s 2025 Budget update). For amounts above £1 million, apply 50% relief. So, for £1.5 million in shares, £1 million is tax-free, and £500,000 gets 50% relief, leaving £250,000 taxable.
Subtract Nil-Rate Bands: Deduct your £325,000 NRB (or £650,000 for couples) and, if passing a home to descendants, the £175,000 Residence Nil-Rate Band (RNRB), provided your estate is under £2 million.
Calculate Taxable Amount: Apply the 40% IHT rate (or 20% on BR-reduced portions post-2026) to the remaining value. Log into www.gov.uk/check-income-tax-current-year to check your NRB usage from past gifts.
Factor in Lifetime Gifts: Gifts made within seven years of death (Potentially Exempt Transfers, or PETs) may reduce your NRB. For example, gifting £100,000 six years ago uses £100,000 of your NRB if the gift fails.
Here’s a sample calculation for a £2 million company:
Step | Calculation | Result |
Share Value | £2,000,000 | £2,000,000 |
Business Relief | 100% on £1m, 50% on £1m | £1m tax-free, £500,000 taxable |
Nil-Rate Band | £325,000 (single person) | £500,000 - £325,000 = £175,000 |
IHT (2026 onwards) | 20% of £175,000 | £35,000 |
This assumes no RNRB or prior gifts. If you’re married, transferring the NRB could wipe out the tax entirely.
Handling Multiple Income Sources
Now, let’s think about your situation – if you’re a business owner with a side hustle or dividends, things get trickier. Multiple income sources can inflate your estate, affecting IHT. For example, a client in Leeds ran a tech company (£1.2m shares) but also earned £50,000 annually from freelance coding. His estate included both the shares and savings from his side hustle. Here’s how to verify:
● List All Assets: Include company shares, savings, investments, and property. Don’t forget pensions – some are IHT-free, but others (like unspent defined contribution pots) aren’t, per HMRC’s 2025 rules.
● Check Income Tax First: Overpaying income tax can reduce savings, shrinking your estate. Use www.gov.uk/check-income-tax-current-year to verify your tax code and ensure you’re not overtaxed on dividends or side income.
● Watch for Double Taxation: Dividends from your company are taxed as income, and the shares are taxed for IHT. A client once missed claiming dividend tax credits, inflating his taxable estate unnecessarily.
Use this Multi-Source IHT Checklist:
● Company shares value: £________
● Other income sources (e.g., freelance, rentals): £________
● Savings/investments: £________
● Property value: £________
● Pension (IHT-exempt?): Y/N
● Total estate: £________
● Estimated NRB/RNRB available: £________
● Potential IHT liability: £________
Scottish and Welsh Variations
Be careful here, because I’ve seen clients trip up when they assume UK-wide IHT rules. Scotland and Wales follow the same IHT rates and thresholds as England (40%, £325,000 NRB), but income tax variations can affect your estate’s size. In Scotland, 2025/26 income tax bands are tighter for higher earners (e.g., 42% intermediate rate from £26,562), meaning less disposable income to save or invest, potentially lowering your estate. Welsh rates mirror England’s, but devolved powers could change this post-2025. Always check your income tax at www.gov.uk/check-income-tax-current-year to see how regional bands impact your savings.
Case Study: Raj’s Tech Firm and Side Hustle
Take Raj, a client in Cardiff with a tech company worth £1.4 million and a side gig earning £30,000 yearly. In 2024, he overpaid income tax due to an incorrect tax code (1257L instead of 1100L, missing his dividends). By correcting this via HMRC’s personal tax account, he reclaimed £2,500, boosting his savings. For IHT, his shares qualified for BR, but post-2026, £400,000 faced 20% IHT (£80,000). We set up a trust for £200,000 of shares, reducing his taxable estate. This saved £40,000 in IHT, showing how verifying income tax and IHT together pays off.
Rare Scenarios: Emergency Tax and High-Income Charges
The big question on your mind might be: what about unusual tax situations? Emergency tax codes (e.g., W1/M1) can overtax new income sources, like a side hustle, reducing your estate’s growth. A client in 2023 was hit with emergency tax on a new contract, losing £3,000 until corrected. Similarly, if you earn over £50,000 and claim Child Benefit, the High-Income Child Benefit Charge claws back benefits, indirectly affecting savings. Check your tax code and Child Benefit status at www.gov.uk/check-income-tax-current-year to avoid these traps.

Advanced IHT Strategies and Tools for Business Owners
So, you’re now clued up on calculating your Inheritance Tax (IHT) liability for your limited company and handling quirks like multiple income sources. Let’s take it up a notch with advanced strategies to minimise IHT, tailored for UK business owners in 2025. In my 15 years advising clients, from Bristol startups to Yorkshire family firms, I’ve seen smart planning slash IHT bills by hundreds of thousands. This part dives into trusts, gifting, and practical tools like a custom planning worksheet, wrapping up with a concise summary of key takeaways to keep you on track.
Can Trusts Save You IHT?
Picture this: You’re staring at a £2 million company valuation, and even with Business Relief (BR), the new £1 million cap from April 2026 means extra tax. Trusts can be a game-changer. A discretionary trust, for instance, lets you gift company shares during your lifetime, potentially removing them from your estate after seven years (a Potentially Exempt Transfer, or PET). I’ve had clients in London use trusts to pass shares to their kids, saving up to 40% IHT. But it’s a bit of a minefield – trusts have their own tax rules, like a 6% charge on assets above £325,000 every 10 years.
Here’s how to set one up:
Choose the Right Trust: Discretionary trusts offer flexibility, letting trustees decide how to distribute assets. Bare trusts fix beneficiaries, ideal for grandchildren.
Gift Shares: Transfer shares to the trust, ensuring they qualify for BR to avoid immediate IHT. Get a valuation first, as HMRC scrutinises this.
Check the Seven-Year Rule: If you survive seven years post-gift, the shares exit your estate. If not, they’re taxed, using up your £325,000 Nil-Rate Band (NRB).
Consult a Professional: Trust law is complex. A client in 2024 set up a trust without advice, triggering a £50,000 IHT bill due to poor structuring. Use www.gov.uk/check-income-tax-current-year to track gifts against your NRB.
Gifting Strategies for IHT Savings
Gifting isn’t just for trusts. You can give £3,000 annually IHT-free (the annual exemption), or more if it’s from regular income without affecting your lifestyle, per HMRC’s 2025 rules. For example, a client in Leeds gifted £10,000 yearly from company dividends to her children, removing £70,000 from her estate over seven years. Be careful, though – gifts to your company (e.g., injecting cash) can complicate BR eligibility if they’re seen as investments. Always document gifts clearly to avoid HMRC disputes.
Optimising Business Deductions
Business owners, listen up: your company’s structure can cut IHT indirectly by reducing your taxable estate. Claim all allowable expenses – travel, equipment, even home office costs – to lower profits and dividends, shrinking your savings pot. A Manchester client in 2023 missed £5,000 in deductions, inflating her taxable income and estate. Check your expenses via www.gov.uk/check-income-tax-current-year and cross-reference with HMRC’s allowable expense list. Also, consider paying into a pension – contributions up to £60,000 annually (2025/26 annual allowance) are IHT-free and reduce your estate.
IHT Planning Options | Benefits | Risks |
Discretionary Trust | Removes shares from estate after 7 years; retains control. | 6% periodic charge; complex setup. |
Annual Gifting | £3,000 IHT-free per year; no impact on lifestyle. | Must be documented; limited impact for large estates. |
Pension Contributions | IHT-free; reduces estate. | Annual limit (£60,000); access restricted until 55. |
Case Study: Emma’s Family Retail Business
Take Emma, a Bristol retailer whose company was worth £1.8 million in 2024. With the new BR cap, £800,000 of her shares faced 20% IHT (£160,000). She transferred £500,000 of shares into a discretionary trust, keeping control via trustees. If she survives seven years, that’s £200,000 IHT saved (40% of £500,000). She also maximised pension contributions, reducing her estate by £40,000 yearly. Emma’s story shows how combining strategies can protect your legacy.
Rare Scenarios: Gig Economy and IR35
The gig economy and IR35 changes can trip you up. If you’re a freelancer with a limited company, IR35 may deem you an employee, increasing income tax and reducing savings, thus affecting your estate. A client in 2024 faced a £10,000 tax hit from an IR35 review, shrinking her IHT-free savings. Check your IR35 status at www.gov.uk/check-income-tax-current-year. Also, gig economy income (e.g., Uber, Deliveroo) often goes unreported, inflating your estate. Use HMRC’s Self Assessment to declare all income and avoid penalties.
Summary of Key Points
IHT is charged at 40% on estates above £325,000, but Business Relief can reduce or eliminate tax on qualifying company shares.
○ From April 2026, BR is capped at £1 million, with 50% relief on excess, leading to 20% IHT.
Verify your company’s trading status to ensure BR eligibility; investment companies don’t qualify.
Calculate your IHT by valuing shares, applying BR, and deducting NRB (£325,000) and RNRB (£175,000, if applicable).
Multiple income sources, like side hustles, can inflate your estate, so check income tax at www.gov.uk/check-income-tax-current-year.
Scottish income tax bands may reduce savings, indirectly lowering your estate; Welsh rates align with England’s for now.
Trusts can remove shares from your estate after seven years, but require careful setup to avoid tax charges.
Gift £3,000 annually IHT-free or more from surplus income to shrink your estate.
Maximise business deductions and pension contributions to reduce taxable income and estate value.
Watch for IR35 or gig economy income errors, which can increase tax and estate size if unreported.
Use worksheets to track share values, gifts, and deductions for accurate IHT planning.
FAQS
Q1: Can someone avoid IHT on their limited company by transferring shares to a spouse before death?
A1: Well, it’s a common question, and the answer’s a bit of a relief. Transferring shares to a spouse or civil partner during your lifetime or on death is usually IHT-free due to the spousal exemption, which covers unlimited transfers between UK-domiciled spouses. For example, a client in Birmingham transferred £1 million in shares to his wife, wiping out any IHT worry for those assets. But here’s the catch: if the spouse later passes away, the shares enter their estate, potentially facing IHT unless Business Relief (BR) applies. Always check BR eligibility first.
Q2: What happens if a limited company holds both trading and investment assets for IHT purposes?
A2: It’s a bit of a grey area, but here’s the deal. HMRC looks at the company’s overall purpose. If it’s mainly trading (e.g., selling goods) but holds some investments (like a rental property), it might still qualify for BR, but only on the trading portion. A client’s retail company in Leeds had a £200,000 investment property; only the trading assets (£1 million) got 100% BR, while the property’s value faced IHT. You’ll need a valuation to split assets clearly and avoid HMRC disputes.
Q3: How does someone know if their limited company shares qualify for Business Relief?
A3: In my experience with clients, the key is checking if your company is a trading business, not an investment one. Trading means actively providing goods or services, like a bakery or tech firm. Investment companies, like those holding stocks or rentals, don’t qualify. A Southampton client’s consultancy got 100% BR, but his property portfolio didn’t. Confirm your company’s activities match HMRC’s trading criteria, and ensure you’ve held shares for two years.
Q4: Can someone reduce IHT by paying themselves a lower salary from their limited company?
A4: It’s a clever thought, but it’s not quite that simple. Lowering your salary reduces income tax, potentially leaving more in the company, but it doesn’t directly cut IHT. The company’s share value, which drives IHT, is based on assets and profits, not your salary. A client in Manchester tried this, only to find her shares’ value rose due to retained profits. Instead, consider pension contributions or gifting surplus income to shrink your estate.
Q5: What if a limited company is sold before death – does IHT still apply?
A5: Here’s where it gets interesting. Selling your company converts shares into cash, which becomes part of your taxable estate, losing BR eligibility. A client sold his £1.5 million business, banking £1.2 million after tax. That cash faced 40% IHT, costing £380,000 on his death. Had he kept the shares, BR could’ve saved it all. Think twice before selling, and plan gifts or trusts to manage IHT.
Q6: How does IHT work for a limited company if the owner lives in Scotland?
A7: Scottish residents face the same IHT rules as England – 40% above £325,000 – but income tax differences matter. Scotland’s tighter 2025/26 bands (e.g., 42% from £26,562) mean higher earners save less, potentially shrinking estates and IHT. A Glasgow client’s high taxes left less cash, lowering her estate’s IHT exposure. Check your income tax to see how it affects your estate’s size.
Q7: Can someone use their pension to reduce IHT on their limited company?
A7: Absolutely, and it’s a strategy I’ve seen work wonders. Pension contributions up to £60,000 annually (2025/26) are IHT-free, as most pensions fall outside your estate. A Bristol business owner paid £40,000 yearly into her pension, cutting her estate by £280,000 over seven years, saving £112,000 in IHT. Just ensure contributions don’t exceed your annual allowance to avoid tax penalties.
Q8: What if a limited company’s shares are held in a trust – are they still IHT-free?
A8: It’s a smart move, but there’s nuance. Shares in a discretionary trust escape your estate after seven years, assuming you survive. However, trusts face their own taxes, like a 6% charge on assets above £325,000 every decade. A client in Cardiff put £500,000 of shares in a trust, saving £200,000 IHT, but faced a £10,000 periodic charge. Weigh trust costs against IHT savings carefully.
Q9: How does someone value their limited company shares for IHT purposes?
A9: Valuing shares is crucial, and I’ve seen clients get this wrong. For unlisted companies, hire a professional valuer to assess assets, profits, and market conditions. A tech startup in London was valued at £1.2 million based on a 4x revenue multiple. HMRC often challenges valuations, so document everything – balance sheets, forecasts, even contracts – to defend your figure.
Q10: Can a limited company owner gift shares to charity to reduce IHT?
A10: Yes, and it’s a win-win. Gifts to UK charities are IHT-free, and if you donate 10% or more of your estate, the IHT rate drops from 40% to 36%. A client gifted £100,000 in shares to a charity, cutting her estate’s tax bill by £16,000 on top of the donation’s relief. Just ensure the charity is HMRC-registered to qualify.
Q11: What happens if a limited company owner dies without a will?
A11: It’s a mess I’ve seen too often. Without a will, intestacy rules distribute your estate, including company shares, to spouse or kids, but IHT still applies. A client in Leeds died intestate, and his £1 million shares faced £270,000 IHT after the NRB, delaying his business’s transfer. Write a will to control share distribution and maximise reliefs like BR.
Q12: Can someone claim BR if their limited company is on the AIM market?
A12: Good news here. Shares in AIM-listed companies often qualify for 100% BR if held for two years, unlike main stock exchange shares. A client’s AIM-listed tech firm got full BR, saving £400,000 in IHT. Confirm your company’s AIM status and holding period to ensure eligibility.
Q13: How does IHT apply if a limited company owner has multiple businesses?
A13: Each company’s shares are valued separately for IHT, with BR applied per company if they’re trading. A client owned a shop (£800,000, BR-eligible) and a property firm (£600,000, not eligible). Only the shop’s shares got relief, leaving £110,000 IHT on the rest after NRB. List all businesses and check their trading status individually.
Q14: What if a limited company owner is non-UK domiciled?
A14: Non-UK domiciled owners face IHT only on UK-situated assets, like company shares if the business operates here. A Dubai-based client with a UK company paid IHT on £1 million in shares but not on overseas assets. If you’ve been UK-resident for 15 of 20 years, you’re deemed domiciled, so plan early to avoid surprises.
Q15: Can someone reduce IHT by reinvesting company profits into growth?
A15: It’s a savvy idea, but it’s indirect. Reinvesting profits boosts share value, which BR can cover if trading. A client reinvested £200,000 into her bakery, raising its value to £1.5 million, all BR-exempt. But if profits become personal savings, they’re taxable. Keep funds in the company to maximise BR.
Q16: How does IHT work if a limited company is in debt?
A16: Debts reduce your company’s share value for IHT. If your company owes £500,000, a £1.5 million valuation drops to £1 million, potentially all BR-exempt. A client’s debt-heavy startup avoided IHT entirely due to low net value. Ensure debts are HMRC-approved to count.
Q17: Can someone use life insurance to cover IHT on their limited company?
A17: Yes, and it’s a strategy I’ve recommended often. A whole-of-life policy in trust pays out IHT-free to cover your tax bill. A client insured £200,000 for her £1 million company, ensuring her heirs weren’t burdened. Policies must be trust-held to avoid adding to your estate.
Q18: What if a limited company owner gifts shares but retains control?
A18: It’s a common mix-up, but retaining control (e.g., as director) doesn’t block IHT relief if gifted to a trust. A client gifted £600,000 in shares to a trust, stayed as CEO, and removed them from her estate after seven years. Just ensure the gift is genuine, not a “gift with reservation” per HMRC rules.
Q19: How does IHT apply to limited company shares held by over-65s?
A19: Age doesn’t change IHT rules, but over-65s often have larger estates from savings or pensions. A client’s £1.2 million shares qualified for BR, but her £300,000 savings added £110,000 IHT after NRB. Use pension contributions or gifting to shrink taxable assets, regardless of age.
Q20: Can someone appeal an HMRC decision on BR eligibility for their company?
A20: Absolutely, and I’ve helped clients do it. If HMRC denies BR, appeal with evidence like financials proving trading status. A Sheffield client overturned a denial for her consultancy, saving £300,000, by showing active contracts. File appeals within 30 days, and consider professional help for complex cases.
