HMRC Business Valuations Explained: Shares, Options and Tax Events
By Bill Anderson, FCCA, Chief Executive Officer, Assetica — 2026-05-08
When HMRC requires a business or share valuation, how the rules work for EMI, gifts, probate and reorganisations, and why independence matters.
When HMRC Needs a Valuation
The most common triggers are EMI and other share option grants, gifts and transfers of shares, probate and inheritance tax, company reorganisations and demergers, and employment-related securities. Each requires a fair market value on a specific date, prepared on the correct basis.
Minority Discounts and Fair Value
HMRC valuations turn on the precise shareholding and rights attached. A minority stake is usually worth less per share than a controlling one, and discounts for lack of control and marketability apply. Applying these correctly is central to a defensible figure.
Why an Independent Report Protects You
An independent valuation prepared to recognised standards, and agreed with HMRC where the process allows, removes uncertainty. It supports the tax treatment you have claimed and protects you from later challenge, additional tax and penalties.
Frequently Asked Questions
When does HMRC require a business valuation?
For EMI and share option grants, share gifts and transfers, probate and inheritance tax, reorganisations, and employment-related securities. Each needs a fair market value on the relevant date.
What is a minority discount?
A reduction applied because a minority shareholding lacks control and is harder to sell. The size depends on the stake, the rights attached, and the company. Applying it correctly is essential for an HMRC-defensible valuation.
Can a valuation be agreed with HMRC in advance?
For some events, such as EMI grants, a valuation can be submitted to HMRC for agreement before the transaction, giving certainty. An independent valuer prepares and supports this submission.
