Valuing a private company isn’t straightforward. Unlike listed companies, where a share price is publicly available at any moment, private company valuations rely on financial analysis, comparable transactions, and methodology that HMRC will actually accept. This guide sets out how it works, what’s required for different situations, and what can go wrong if it’s done poorly.
What Is a Company Valuation?
A company valuation is the process of determining the economic value of a business as a whole. It’s commonly required for:
- Share issues and transfers
- Employee ownership schemes
- Business sales or acquisitions
- Tax and HMRC reporting purposes
Because private companies have no public market price, the valuation has to be built up from accepted financial methodologies rather than simply read off an exchange.
Share Valuation vs Company Valuation
The two terms get used interchangeably, but they answer different questions:
- Company valuation determines the value of the whole business
- Share valuation determines the value of individual shares within that business
Both matter in employee ownership and tax planning structures, and the relationship between them isn’t always a simple division. A minority shareholding, for instance, is rarely worth a straight proportional slice of the whole company’s value; discounts for lack of control or lack of marketability often apply, which is one of the more common places a valuation gets challenged.
When You Need a Share Valuation
Share valuations are essential for:
- Employee share schemes
- Share option pricing under EMI and CSOP
- Transfers between shareholders
- Trust-based share arrangements, including EOTs
- Exit planning and succession
The Four Main Valuation Methods
The methodology chosen, and the inputs fed into it, have a direct impact on the outcome and on how HMRC views the submission. The main approaches used in UK share scheme and company valuations are:
- Earnings-based valuation (P/E multiple). Applies a sector-appropriate multiple to maintainable earnings. This is the most common method for trading companies, since it reflects what the business actually generates rather than what it owns.
- Net asset valuation. Used for asset-rich or investment holding companies, where the value sits in the balance sheet rather than in trading profit.
- Discounted cash flow (DCF). Applied where future cash flows can be reliably projected. More common for businesses with predictable, contracted revenue than for early-stage or volatile companies.
- Comparable transaction analysis. Uses recent deals in the same sector to benchmark value, useful as a sense check against whichever primary method is used, and often requested by HMRC as supporting evidence.

What’s Required for Different Share Schemes
- EMI valuations are submitted to HMRC for agreement before options are granted. Get this wrong and the options can lose their tax-advantaged status entirely.
- CSOP valuations must reflect market value at the date of grant. HMRC doesn’t pre-approve these, but will scrutinise them on enquiry.
- EOT valuations must represent genuine market value for the trust purchase to qualify for Capital Gains Tax relief.
- Growth share valuations require specialist analysis of the company’s capital structure and waterfall, to determine the hurdle rate and current value of the growth shares.
Why Accurate Valuations Matter
HMRC applies strict scrutiny to valuation submissions, and with routine valuation checks no longer offered, an independent expert valuation matters more than it used to. An incorrect valuation can lead to:
- Unexpected tax liabilities
- Penalties or adjustments
- Rejection of share schemes
- Disputes during transactions
A properly prepared valuation, using a defensible methodology and clear documentation, is what stands between a routine HMRC enquiry and a costly one.
Frequently Asked Questions
What’s the difference between a company valuation and a share valuation?
A company valuation determines the value of the whole business. A share valuation determines the value of individual shares within it, which isn’t always a simple proportional slice, particularly for minority holdings.
Why does HMRC care about share valuations?
Accurate valuations are what HMRC relies on to check correct tax treatment on employee share schemes and related transactions. An unsupported or aggressive valuation is one of the more common triggers for an HMRC enquiry.
How long does a company valuation take?
Typically a few days for the analysis itself, extending to several weeks where formal HMRC agreement is required, as with EMI.
Which valuation method will apply to my business?
It depends on the type of company. Trading companies with maintainable earnings usually suit an earnings-based approach; asset-rich or holding companies usually suit net asset valuation; businesses with strong, predictable future cash flow may suit DCF. Often more than one method is used together, with comparable transactions as a check.
