Are Limited Companies Subject to Inheritance Tax? The Complete Guide
Business owners often ask are limited companies subject to inheritance tax. The company itself does not pay Inheritance Tax. The tax falls on the shareholder’s estate, and whether relief applies depends mainly on business property relief and whether the business is genuinely trading.
If you are also looking to get the broader picture of what directors are responsible for across tax, payroll, record keeping, and compliance, our guide to running a limited company is a useful starting point. This guide gives a brief overview for company owners: business property relief and excepted assets such as surplus cash, how shares are valued and minority discounts applied, lifetime gifts and CGT hold-over, cross-option arrangements for succession, and a simple decision flow with a real client case study.
Are Limited Companies Subject to Inheritance Tax: who actually pays?
Inheritance Tax is assessed on the value of the shares a person owns when they die, not on the company. Executors calculate the estate, claim reliefs, and pay any tax that is due.
HMRC’s Shares and Assets Valuation guidance explains how unquoted shares are valued, including how minority holdings may attract discounts to reflect reduced control.
Business Property Relief basics for company owners
business property relief, often called Business Relief, can reduce the Inheritance Tax value of qualifying business assets. Shares in an unlisted trading company commonly attract 100% relief if the conditions are met.
Some interests in businesses and assets used by a company you control attract 50% relief. See the statutory framework in the Inheritance Tax Act 1984 section 105 and HMRC’s overview of Business Relief.
The trading test in practice
HMRC looks at whether the company is wholly or mainly trading rather than investing. Significant investment activity, property letting, or large portfolios can point away from trading. HMRC’s Inheritance Tax Manual explains how mixed activity companies and groups are assessed, and how excepted assets can restrict relief.
Ownership periods and replacements
Usually you must have owned the asset for at least two years before death to claim relief. Replacement property rules may allow relief where business assets are swapped during that period if conditions are met.
Excepted assets and surplus cash
Even if the company is trading, business property relief can be restricted if there are excepted assets. These are assets not used wholly or mainly for the business, such as surplus cash or investments that are not required for working capital.
HMRC’s guidance sets out indicators and case examples of cash balances that are more than the reasonable needs of the trade. HMRC’s Shares and Assets Valuation notes also discuss how surplus funds and non‑business assets are reflected in valuations.
Control, valuation and minority discounts
For owners asking are limited companies subject to inheritance tax, the value for Inheritance Tax is what a willing buyer would pay for the holding at the date of death. A majority holding that confers control is usually worth more than the same number of shares split between several owners.
A small stake can be discounted for lack of control and marketability. HMRC’s guidance for valuers sets out accepted approaches to minority discounts in private companies.
Lifetime planning with shares: PETs, CLTs and CGT hold‑over
Gifts to individuals
A gift of shares to an individual is usually a Potentially Exempt Transfer. If the donor survives seven years the gift becomes exempt for Inheritance Tax.
Gifts into most trusts are Chargeable Lifetime Transfers, which may create a lifetime charge. GOV.UK summarises the seven year rules and exemptions for gifts.
Capital Gains Tax on gifts
Capital Gains Tax can arise on a lifetime gift. If the shares qualify as business assets, hold‑over relief may defer the gain so no immediate CGT is payable. The recipient takes the asset at a reduced base cost (GOV.UK Gift Hold‑Over Relief and HMRC CG manual CG66880+).
Directors’ loan accounts and cash on the balance sheet
A director’s loan account can affect both the estate and business property relief analysis. A loan owed by the company to the shareholder is an asset of the estate at face value. A loan owed by the shareholder to the company increases the estate indirectly because the shares may be worth more once the loan is cleared. Large cash balances can invite an excepted assets review that reduces Business Property Relief.
Cross‑option and buy sell arrangements
The type of agreement in place for succession can affect relief. A binding buy and sell agreement can prevent business property relief because it fixes a contract to sell the shares, whereas a cross‑option usually preserves relief if structured correctly.
HMRC’s Inheritance Tax Manual explains the difference between a binding contract for sale and an option arrangement. Life insurance written in trust is often used to provide liquidity for a cross‑option on death.
Group structures, investment companies and AIM shares
Trading activity across the group
Groups and mixed activity businesses need to show the overall activity is trading and that assets are used for the trade. Each subsidiary’s contribution is reviewed to ensure the group is mainly trading rather than investing.
Investment companies and passive subsidiaries
Passive or investment companies generally do not qualify for relief. If a holding or property subsidiary dominates the balance sheet, relief can be restricted.
AIM-listed shares
Shares quoted on AIM can qualify for 100% relief if the underlying company is trading and other conditions are met. HMRC’s manuals discuss group issues, excepted assets in groups, and the treatment of trading shares quoted on junior markets.

Trust planning with company shares at a glance
Trusts can be used to pass shares while managing control and succession. For owners wondering are limited companies subject to inheritance tax, trusts are one way to plan succession without transferring control immediately.
Gifts of shares to most trusts are chargeable lifetime transfers, and periodic and exit charges may arise. In some cases CGT hold‑over under section 260 or section 165 may be available. GOV.UK explains how Inheritance Tax applies to trusts and the main thresholds and charges.
Decision flow: does my shareholding qualify for Business Property Relief?
Step 1: Identify the company type
Is it wholly or mainly a trading company rather than an investment company? Check activities, revenue mix and assets.
Step 2: Check the ownership period
Have the shares been held for at least two years, or do the replacement property rules apply?
Step 3: Review excepted assets
Is there surplus cash or other assets not required for the trade that could restrict relief?
Step 4: Examine agreements
Is there a binding buy and sell agreement that could block relief, or a cross‑option that usually preserves it?
Step 5: Consider valuation and control
Is the holding a minority or majority interest, and how might that affect value and the overall tax position?
Client case study: £2 million trading company, two shareholders
Background
Using this case study as an example, an anonymised client, “D Ltd”, an unquoted trading company was valued at about £2,000,000. Shareholder A held 70% and Shareholder B held 30%. The company carried £150,000 of cash above normal working capital and had no investment portfolio. A cross option agreement was in place funded by life insurance held in trust.
What we did
We reviewed trading versus investment activity and confirmed the trading test. We separated cash balances into working capital and surplus to assess any excepted asset restriction.
We obtained an indicative valuation that reflected control for A’s 70% holding and a minority discount for B’s 30% holding. We also checked that the cross option, rather than a binding buy and sell agreement, preserved potential relief.
Result
With records in good order, A’s estate was able to claim near full business property relief on the trading element, with a proportionate restriction for surplus cash. B’s position reflected a minority discount and the same surplus cash adjustment.
The policy in trust provided liquidity to exercise the option so shares transferred smoothly without a forced sale.

Wrapping Up
For owner‑managers and family businesses the key question is not simply are limited companies subject to inheritance tax, but whether your shares qualify for business property relief and whether any excepted assets or agreements limit that relief. With the right structure, ownership period and documentation, many trading company shares can qualify for substantial relief.
FAQs
Do limited companies themselves pay Inheritance Tax?
No. Inheritance Tax is charged on the shareholder’s estate, not on the company. The company continues to be subject to Corporation Tax on its profits.
Does surplus cash stop Business Property Relief?
It can reduce relief. Cash and other assets that are not required for the trade can be treated as excepted assets, which restrict the relief claim.
Can I give shares to family to reduce Inheritance Tax?
A gift to an individual is usually a Potentially Exempt Transfer. Survive seven years and it becomes exempt. Gifts to most trusts are Chargeable Lifetime Transfers. Capital Gains Tax can arise, although hold‑over relief may defer the gain for qualifying business assets.
Do AIM shares qualify for Business Property Relief?
They can. Shares quoted on AIM may qualify for 100% relief if the underlying company is trading and the ownership period and other conditions are met.
Will a shareholder agreement affect relief?
A binding buy and sell agreement can block business property relief because it creates a contract to sell. A cross‑option is usually compatible with relief if structured correctly.
