HMRC EMI Valuation: UK Founder’s Guide to Getting It Right

Most UK founders discover the cost of a bad EMI valuation only after HMRC rejects it. A failed HMRC EMI valuation does not just delay your scheme launch – it can invalidate option grants already made, trigger tax liabilities for employees, and restart a compliance process that takes weeks. HMRC’s Shares and Assets Valuation team (SAV) receives thousands of submissions annually and has clear, documented expectations. Yet a significant number of first-time submissions from SMEs contain avoidable errors: unsupported discount rates, missing articles of association, or valuations produced by advisers who lack experience with restricted shares. This guide tells you exactly what SAV expects and how to get your valuation agreed first time.

What Is HMRC SAV and Why Does It Matter for EMI

HMRC’s Shares and Assets Valuation (SAV) team is the specialist unit responsible for agreeing the market value of shares in private companies for tax purposes. For Enterprise Management Incentive schemes, SAV handles the pre-grant valuation agreement process under which an employer can submit a proposed share value for HMRC review before issuing options to employees.

The process is voluntary. HMRC does not compel you to seek pre-agreement. But in practice, any founder who skips it is taking a material risk. If HMRC later disagrees with your valuation, employees who exercised options could face retrospective income tax on what HMRC considers an undervalued grant. That is not a theoretical risk – it has happened to SME employees who had no idea their options carried a tax exposure.

SAV operates within HMRC’s Valuation Office function and applies internally consistent standards that draw on established case law, including the seminal Lynall v IRC and IRC v Crossman decisions. Understanding these standards is not optional if you want a first-time agreement.

“The value of shares in a private company is always a matter of judgment, but judgment informed by systematic analysis – not a figure plucked from a spreadsheet.” – ICAEW Tax Faculty, guidance on unlisted securities valuation

Pro tip: Submit your SAV application well before your intended grant date. HMRC SAV currently takes between four and ten weeks to process submissions, and that window can stretch during peak periods. Build this into your EMI launch timeline from day one.

EMI Scheme Eligibility: What Qualifies Before You Value Anything

Before spending time on valuation, confirm your company qualifies for EMI. HMRC sets strict eligibility criteria and a valuation submission made for an ineligible company is wasted time and money.

Company-Level Requirements

Your company must be an independent UK trading company with gross assets not exceeding £30 million at the time of grant. The company must have fewer than 250 full-time equivalent employees. Certain trading activities disqualify a company entirely: property development, financial services, legal and accounting services, farming, and hotel management are excluded trades under Schedule 5 ITEPA 2003.

The company must also not be a subsidiary of, or under the control of, another company. This rules out most portfolio companies held by institutional investors with majority control, which is a common sticking point for founder-led businesses that have taken institutional funding at Series A or beyond.

Employee-Level Requirements

Eligible employees must work at least 25 hours per week for the company, or if less, at least 75% of their working time. Employees who hold more than 30% of the company’s shares (including associate holdings) are excluded. Individual option limits are capped at £250,000 of options outstanding at any one time, measured by AMV at grant. The company-wide limit is £3 million.

Getting eligibility wrong does not just mean a failed valuation – it means the entire scheme fails HMRC’s qualifying conditions, and employees lose all EMI tax advantages. Confirm eligibility with a qualified adviser before instructing any valuation work.

What HMRC SAV Actually Reviews in Your Valuation

When SAV receives your submission, their valuers are not simply checking a number. They are stress-testing the assumptions behind it. Understanding their review process directly shapes how you build your submission.

The Distinction Between AMV and RMV

Actual Market Value (AMV) is the unrestricted open-market value of the share, assuming a willing buyer and seller with full information. Restricted Market Value (RMV) applies where shares are subject to restrictions that a purchaser in the open market would take into account when pricing, such as drag-along obligations, compulsory transfer on leaving employment, or pre-emption rights. RMV is always lower than or equal to AMV.

For EMI purposes, options are typically granted at RMV (the lower figure), which reduces the strike price employees pay. But HMRC requires you to agree both AMV and RMV if you are granting at a discount to AMV. Submitting only one figure when both are relevant is one of the most common reasons SAV requests further information.

Supporting Documentation SAV Expects

SAV routinely asks for the following alongside your valuation report: the company’s latest audited or management accounts, the articles of association, details of any recent third-party transactions in the company’s shares, your cap table, and any shareholder agreements that affect rights or restrictions attaching to shares. Missing any of these delays the process by weeks.

If the company has received external investment in the last 18 to 24 months, SAV will scrutinise the implied valuation from that round carefully. If your proposed EMI valuation sits materially below the implied investment round valuation, you need a credible, documented explanation. A narrative without supporting analysis will not satisfy SAV.

Pro tip: Include a specific section in your valuation report that directly addresses any recent funding rounds and explains, with quantified reasoning, any discount applied relative to the investment round price. SAV valuers appreciate submissions that anticipate their questions.

Valuation Methods HMRC Accepts for EMI Share Valuations

HMRC SAV does not prescribe a single valuation method. It expects the method to be appropriate to the company’s stage, sector, and financial profile. In practice, three approaches dominate defensible EMI submissions for UK SMEs.

Discounted Cash Flow (DCF)

DCF is appropriate for companies with a degree of trading history and reasonably foreseeable cash flows. It projects free cash flows over a five to ten year period and discounts them at a risk-adjusted rate to arrive at an enterprise value. The discount rate is critical – SAV will challenge any Weighted Average Cost of Capital (WACC) that is not grounded in comparable public company data and SME-specific risk premia. Using a rate below 15% for an early-stage UK SME without strong justification invites a counter-argument from SAV.

EBITDA Multiples from Comparable Transactions

For profitable SMEs, applying an earnings multiple to maintainable EBITDA is often the most defensible method because it anchors value to observable market data. The multiple must come from genuinely comparable transactions, not from publicly listed companies without a size discount. UK SME transactions typically trade at a meaningful discount to listed multiples, and failing to apply that discount is a common submission error. Databases such as Argus, Refinitiv, or Capital IQ provide the transaction evidence that SAV expects to see referenced.

Net Assets or Asset-Based Valuation

Asset-based approaches are appropriate for asset-heavy businesses or holding companies where the going-concern value approximates net asset value. For most trading SMEs, however, a pure net asset approach understates value. SAV will question whether a trading company’s valuation on a net asset basis adequately reflects its earnings potential and goodwill.

In practice, a well-constructed EMI submission often uses a primary method supported by a cross-check from a secondary method. This dual-method approach gives SAV confidence that the valuer has tested their conclusion against the market, not just produced a single model in isolation.

Comparing Valuation Approaches for EMI Submissions

The choice between methods is not purely technical – it is also strategic. A founder preparing for an EMI scheme wants a valuation that is as low as defensible (to keep employee strike prices attractive) while remaining credible enough that SAV agrees it on first review. These two objectives require a practitioner who understands both the technical standards and the practical dynamics of SAV negotiations.

Common Mistakes That Cause SAV Rejections

After reviewing numerous EMI valuation submissions, the failure patterns are consistent. These are not edge-case errors – they appear repeatedly in submissions prepared without specialist valuation input.

Using an Accountant Without Valuation Expertise

Your company’s existing accountant can prepare statutory accounts, but preparing a defensible share valuation is a different discipline. A common mistake is instructing an accountant who produces a valuation based on book value or a simple P/E ratio without engaging with SAV’s methodological expectations. SAV can and does request revised submissions when the methodology is inadequate, and each revision cycle adds weeks to your timeline.

Ignoring the Impact of a Recent Funding Round

If your company raised equity at a valuation of, say, £5 million six months ago, submitting an EMI valuation of £1.5 million without a rigorous, documented explanation will trigger an immediate SAV query. Founders often underestimate how closely SAV tracks implied valuations from recent transactions. The discount applied must be supported by specific, quantified factors: preference share liquidation preferences, different share class rights, market conditions at the time of the round, or changes in business performance since the raise.

Failing to Identify All Share Restrictions

Every restriction in your articles of association or shareholder agreement that affects the economic value or transferability of shares must be identified and quantified in the RMV calculation. Founders frequently miss the impact of leaver provisions (good leaver versus bad leaver buyback prices), pre-emption rights, or consent requirements for transfer. Each restriction should carry a separately documented discount with a stated rationale.

Submitting Without a Written Valuation Report

Some founders submit the SAV application with a single-page summary or a spreadsheet with no accompanying narrative. SAV requires a proper written valuation report that explains the approach, sources, assumptions, and conclusion. A spreadsheet alone is not a valuation report by any professional standard – not by RICS, not by ICAEW, and not by SAV’s own expectations. A bare submission will be returned with a request for further information before SAV even begins its substantive review.

How to Prepare a Defensible EMI Valuation Submission

A defensible submission is one that HMRC SAV can agree without requesting further information. That is the standard to target. Anything less increases your timeline, your costs, and the risk of a negotiated outcome that does not serve your scheme objectives.

Document Your Assumptions Explicitly

Every assumption in your model – revenue growth rates, margins, discount rate, terminal growth rate, EBITDA multiples – must be stated and sourced. Do not use assumptions without citing the basis. If your discount rate uses a 2% equity risk premium sourced from Damodaran’s country risk premium data, say so. If your revenue growth assumptions are based on signed contracts or a board-approved forecast, reference that explicitly. SAV valuers are trained to identify assumption-driven results that are not grounded in evidence.

Address the AMV and RMV Separately and Completely

Structure your report so that AMV is determined first using your primary methodology, and RMV is then derived by applying documented discounts for each identified restriction. For each restriction, state: (a) what the restriction is, (b) why it would affect a purchaser’s price, and (c) the quantified discount applied. A table format for this section helps SAV reviewers navigate the analysis quickly and reduces the risk of a query based on a missed restriction.

Include Comparable Transaction Evidence

Even if your primary method is DCF, include a comparable transactions section as a cross-check. Pull transaction data from a recognised database, filter for sector, deal size, and geography, and document the implied multiples. Then show how your conclusion compares to that data. If your value sits below the median transaction multiple, explain why (growth profile, profitability, customer concentration, IP ownership). If it sits above, you need an even stronger justification.

Pro tip: If your company has had any arm’s length transactions in its own shares – a secondary sale, a buy-back, or an ESOP transaction – include that data. SAV gives significant weight to actual transactions in the same class of shares, even at small volumes, as direct market evidence.

Working With a Valuation Specialist: What Good Looks Like

Not all advisers offering EMI valuation services apply the same standards. The difference between a submission that SAV agrees first time and one that goes back and forth for three months often comes down to the quality and credentials of the adviser preparing it.

What Credentials to Look For

Look for advisers with direct experience in HMRC SAV submissions, not just general corporate finance work. Relevant credentials include ICAEW membership, ACA qualification, and experience specifically with EMI schemes and SAV negotiations. Big Four and investment banking backgrounds matter because they indicate familiarity with the methodological rigour SAV expects. An adviser who has personally handled SAV queries and negotiations will structure submissions differently from one who has only prepared valuations for internal use.

Fixed Fees vs Hourly Billing

Hourly billing creates misaligned incentives when it comes to SAV submissions. If your adviser charges by the hour, a back-and-forth with SAV generates more revenue for them. A fixed-fee model aligns the adviser’s interest with yours: getting agreement first time. When evaluating valuation providers, ask directly whether the fee covers a single submission and one round of SAV queries, or whether additional rounds attract additional charges. This question alone will tell you a great deal about how the adviser approaches the work.

Independence Matters for Credibility

An independent valuation – one produced by a firm that has no financial stake in the outcome of the scheme – carries more weight with SAV than an internally produced figure or one prepared by a party connected to the transaction. This is the same standard applied in litigation support valuations and fairness opinions. If your valuation is ever challenged by HMRC in an enquiry, independence is one of the first things the inspector will examine.

At Consult EFC, we apply ICAEW-grade methodology to every EMI share valuation submission, combining DCF modelling with comparable transaction research drawn from professional databases. Our partner-led service means the person who signs the report is the person who built it and understands every assumption in it – not a junior analyst. That distinction matters when SAV comes back with questions.

Frequently Asked Questions

Do I have to get HMRC to agree my EMI valuation before granting options?

No, pre-agreement with HMRC SAV is not legally required. However, without an agreed valuation, employees who exercise their options cannot be certain they will not face an income tax charge on the difference between the option price and what HMRC later determines the shares were worth at grant. In practice, skipping pre-agreement is a risk that most well-advised founders choose not to take.

How long does HMRC SAV take to agree an EMI valuation?

HMRC SAV’s current processing times range from four to ten weeks for straightforward submissions. Complex submissions, those involving recent funding rounds, preference share structures, or businesses with multi-jurisdictional operations, can take longer. If SAV requests further information, each additional exchange adds two to four weeks. A well-prepared first submission is the most effective way to control timeline.

What is the difference between AMV and RMV for EMI purposes?

Actual Market Value (AMV) is the unrestricted market value of the share. Restricted Market Value (RMV) is a lower figure that reflects the restrictions attaching to the specific shares being optioned, such as leaver provisions, drag-along rights, or pre-emption rights. Options are usually granted at or above RMV. Both values must be agreed with SAV if you are granting at a price below AMV, because the tax treatment on exercise differs depending on the relationship between the exercise price and both AMV and RMV.

Can I use the same EMI valuation for multiple grant dates?

No. An agreed SAV valuation is valid for a specific date and a 90-day window from that date within which options must be granted. If you intend to make further grants after that window, or if material changes have occurred in the business, you need a new SAV application. Many companies with rolling EMI schemes arrange for a new valuation each financial year or each time a significant new hire joins the scheme.

What happens if HMRC disagrees with my EMI valuation after options have been exercised?

If HMRC opens an enquiry and successfully argues that the original valuation was too low, the difference between the agreed value and HMRC’s higher figure is treated as employment income for the employee in the year of exercise. This creates an income tax and potentially a National Insurance liability. The employer may also face secondary NIC exposure. This is exactly the scenario that a pre-agreed SAV valuation is designed to prevent, which is why defensible documentation – even years after the event – matters.

How much does an independent EMI share valuation cost?

Costs vary significantly depending on the complexity of the business and the depth of analysis required. Simple, profitable SMEs with clean share structures and two years of accounts may cost between £1,500 and £3,000 for a professionally prepared submission. More complex businesses, particularly those with recent funding rounds, convertible instruments, or complex articles, will attract higher fees. Comparing providers on price alone is a false economy – a rejected or queried submission costs more in adviser time and delay than the original saving on fees.

If you have recently been through an EMI valuation process or are preparing to launch a scheme, share what you found most challenging – your experience could be useful to other founders navigating the same process.
