Inheritance Tax on Limited Company Shares: Business Relief After April 2026

Short answer

Shares in your limited company are part of your estate for Inheritance Tax. Shares in an unlisted trading company usually qualify for Business Relief if you have owned them for at least two years. For deaths on or after 6 April 2026, 100% relief applies to the first £2.5 million of combined business and agricultural property, with 50% relief above that. Unused allowance can pass to a spouse or civil partner. Companies that mainly hold investments or let property do not qualify.

Do your limited company shares count for inheritance tax? How Business Relief works from 6 April 2026, the £2.5m 100% allowance, the investment-company trap and what directors should check.

Last updated 10 November 2026. Official references are listed below.

Are company shares subject to inheritance tax?

Yes. Your shares are valued at market value and added to the rest of your estate. Business Relief then reduces that value, before the nil-rate band of £325,000 and any residence nil-rate band are applied. Executors claim the relief on form IHT400 with schedule IHT413.

Which shares qualify for Business Relief

  • Unlisted trading companies, including most owner-managed limited companies.
  • You must normally have owned the shares for at least two years.
  • Not companies that mainly deal in securities, land or buildings, or make or hold investments. Most buy-to-let and property-holding companies fail this test.
  • Not companies being sold under a binding contract or being wound up, with limited exceptions.

Assets not needed for the business, including surplus cash, can be excluded from relief.

The £2.5 million allowance from 6 April 2026

SituationRelief
First £2.5 million of qualifying business and agricultural property100%
Qualifying property above £2.5 million50% (an effective 20% Inheritance Tax rate)
Shares on markets HMRC does not treat as listed, such as AIM50%, and they do not use the allowance
Unused allowance of a late spouse or civil partnerCan be transferred, giving up to £5 million

Executors must claim the transferred allowance by the later of 4 years after the death or 6 months after they start acting.

Qualifying gifts made on or after 30 October 2024 use the allowance first if you die within seven years. If the first spouse died before 6 April 2026, the full £2.5 million is treated as available to transfer. Tax on qualifying business property can be paid in 10 equal annual instalments, interest-free.

Can you gift shares in a limited company?

Yes. A gift to an individual is usually a potentially exempt transfer, so it falls outside your estate if you survive seven years. For Capital Gains Tax, a gift counts as a disposal at market value, but gift holdover relief can often defer the gain on shares in an unlisted trading company. The transfer is recorded on a stock transfer form and in the company's register of members.

If you die within seven years of the gift, Business Relief only applies if the recipient still owns the shares and they still qualify, for example the company is still trading and unlisted.

What directors should check now

  1. Is the company clearly trading, or has investment or property activity crept in?
  2. Roughly what are your shares worth, and is your combined business property near £2.5 million?
  3. Is cash building up that the business does not need?
  4. Do your will, articles and shareholders' agreement say what happens to your shares?
  5. Would gifts during your lifetime, or holdings with a spouse, use the allowances better?

Frequently asked

Frequently asked questions

Will my family pay inheritance tax on my shares?

Often not, if the shares qualify for 100% Business Relief and fall within the £2.5 million allowance.

Does a property company qualify?

Usually not. A company that mainly lets property is treated as an investment business.

What if I've owned the shares for under two years?

Business Relief generally won't apply, although replacement-property rules can help, for example after incorporating a sole trade.

Are AIM shares treated the same way?

No. From 6 April 2026 they get 50% relief and do not use the £2.5 million allowance.
