Why Do I Need a Valuation to Set Up a Share Scheme?

Setting Up a Share Scheme: Why Valuation Comes First

Employee share schemes are one of the most powerful tools available to UK SMEs for attracting, retaining, and motivating talent. Whether you are considering an Enterprise Management Incentive (EMI), a Company Share Option Plan (CSOP), a growth share scheme, or unapproved options, one step is non-negotiable: obtaining an independent share valuation before options are granted.

Many founders ask the same question: *"Why do I actually need a valuation? Can't I just pick a number?"* The short answer is no - and the consequences of skipping or mishandling this step can be significant.

The Core Reason: HMRC Compliance

Most UK share schemes derive their tax advantages from compliance with HMRC rules. At the heart of those rules is the requirement that options are granted at a defensible market value at the date of grant.

EMI Schemes

For EMI options, HMRC offers an Advance Assurance process: you submit a valuation report (the VAL231 form alongside a supporting valuation) and HMRC agrees the unrestricted market value (UMV) and actual market value (AMV) of the shares. Once agreed, that valuation is valid for 120 days, giving you a window to grant options with certainty over the tax treatment.

Without an agreed valuation:

• Employees may be exposed to income tax and National Insurance on the gain at exercise
• The company may lose its Corporation Tax deduction
• The scheme may fall outside the EMI regime entirely

CSOP and Unapproved Schemes

CSOPs also rely on the market value at grant to determine whether options qualify for tax-advantaged treatment. Unapproved schemes do not require HMRC agreement, but a robust valuation is still essential to:

• Set a fair exercise price
• Evidence the position in the event of an HMRC enquiry
• Avoid disputes with employees later on

Protecting Employees from Unexpected Tax Bills

A share scheme is meant to reward your team - not to hand them a surprise tax liability. If options are granted at an exercise price below market value (and the scheme is not structured to accommodate that), the discount can be treated as employment income, taxable through PAYE.

A proper valuation ensures:

• The exercise price is set at a defensible level
• Employees understand the tax position from day one
• The scheme delivers the incentive value it was designed for

Supporting the Commercial Logic of the Scheme

Beyond compliance, valuation underpins the commercial design of your share scheme. Key questions a valuation helps answer include:

• How many shares should we allocate to the option pool?
• What percentage of equity will employees hold on exercise?
• What is the realistic upside for participants in different exit scenarios?
• Should we use ordinary shares, growth shares, or a hurdle structure?

Without a clear view of value, these decisions are made in the dark - often leading to over- or under-allocation of equity.

Reducing the Risk of HMRC Challenge

HMRC can review share scheme arrangements years after grant, particularly during due diligence on a sale or fundraise. If the valuation underpinning the scheme is weak, undocumented, or inconsistent with later events, the consequences can include:

• Reassessment of tax due
• Interest and penalties
• Disruption to a transaction or exit

A professionally prepared valuation report - supported by recognised methodologies and clear assumptions - provides a contemporaneous record that can be relied upon if questions arise later.

What a Good Share Scheme Valuation Looks Like

A high-quality valuation for share scheme purposes typically includes:

• Company overview and commercial context - sector, business model, stage of development
• Financial analysis - historical performance and forward projections
• Methodology selection - usually a combination of market multiples, DCF, and asset-based approaches
• Discounts for lack of marketability and minority interest, where appropriate
• Treatment of share rights - preference shares, growth shares, hurdles
• Conclusion of UMV and AMV for HMRC purposes

The report should be clear enough for HMRC, your accountants, and your board to understand and rely upon.

Common Mistakes to Avoid

We regularly see UK SMEs run into avoidable issues, including:

1. Using the last funding round price without adjustment for share class differences
2. Applying generic discounts without justification
3. Granting options before HMRC valuation is agreed, then discovering the price needs to change
4. Ignoring restrictions on shares, which can materially affect AMV
5. Failing to refresh the valuation when granting new options outside the 120-day window

Each of these can undermine the tax efficiency - and credibility - of the scheme.

When Should You Get the Valuation?

The valuation should be one of the first steps in setting up a share scheme, not an afterthought. A typical sequence looks like:

1. Decide on scheme type (EMI, CSOP, growth shares, unapproved)
2. Engage an independent valuer
3. Obtain HMRC Advance Assurance (for EMI)
4. Finalise scheme rules and option agreements
5. Grant options within the validity window
6. File required notifications with HMRC

Trying to retro-fit a valuation after options have been granted is rarely a good outcome.
