EMI Share Option Schemes: A Complete Guide for UK Companies

Setting Up an EMI Scheme? Get the Finance Leadership Right From the Outset

The Enterprise Management Incentive (EMI) scheme is the most tax-efficient way for a UK growth company to give employees a meaningful stake in the business. It lets you grant share options to key people — with the full backing of HMRC approval — using a structure that produces significantly better tax outcomes than an unapproved option arrangement or a direct share award.

For the right company, EMI is transformative: it allows a cash-constrained business to attract and retain talent that would otherwise be unaffordable, align the interests of employees with long-term company value, and create a compelling incentive that vests through genuine contribution rather than just tenure.

But EMI is not a set-and-forget exercise. The setup requires an HMRC-approved valuation, a carefully structured option agreement, a notification submitted within a strict 92-day window, and an annual Employment-Related Securities (ERS) return filed with HMRC each tax year. Miss a step — or let a disqualifying event go unnoticed during the life of the scheme — and the tax advantages that make EMI worthwhile can be lost entirely.

This guide is written for founders, CEOs and Finance Directors at UK growth companies. It explains what EMI is, how it works, what the eligibility requirements are, and — critically — why the Finance Director or CFO plays a central role in getting the scheme set up correctly and keeping it compliant over time. At the end, you will find information about how FD Capital places Finance Directors and CFOs who have direct hands-on experience of EMI scheme setup and management.

What Is an EMI Scheme and Why Do Growth Companies Use It

EMI — Enterprise Management Incentives — is a government-approved share option scheme, created under Schedule 5 of the Income Tax (Earnings and Pensions) Act 2003 and administered by HMRC. It allows qualifying companies to grant options over shares to eligible employees, with the options attracting favourable income tax and capital gains tax treatment on exercise and eventual sale.

The scheme was designed specifically for small and medium-sized growth companies that need to compete for talent against larger employers who can offer higher salaries. By enabling employees to share in the increase in company value — tax-efficiently — it gives growth companies a genuinely competitive tool for attraction and retention.

Why EMI rather than other share schemes

There are several ways to give employees equity in a UK company. EMI is typically the most attractive for growth companies for four reasons:

• No income tax on grant. Employees pay no income tax or National Insurance when options are granted, provided the exercise price is at or above the market value agreed with HMRC at the time of grant.
• Capital gains tax on exit, not income tax. When employees exercise their options and sell the resulting shares, the gain is treated as a capital gain rather than employment income — taxed at 10% (if Business Asset Disposal Relief applies) or 20% at the most, rather than up to 45% income tax plus NIC.
• Corporation tax deduction. The company receives a corporation tax deduction equal to the difference between the market value of the shares at the time of exercise and the exercise price paid by the employee. For a company with rising share values, this can be a significant deduction.
• HMRC-approved — no need for HMRC discretion. Unlike some other schemes, EMI operates on a statutory framework. If the company and the options meet the conditions, the tax treatment follows automatically. There is no need to seek HMRC’s individual approval for each grant (though advance valuation agreement is standard practice).

EMI vs CSOP vs unapproved options vs growth shares

For the typical UK growth company with fewer than 250 employees, EMI is the starting point. The question is whether the company qualifies — and if it does, how to set the scheme up correctly from the outset.

EMI Eligibility — Does Your Company Qualify

EMI has both company-level and employee-level eligibility requirements. Both sets of conditions must be met on the date each option is granted. Failure to meet either set means the option will not qualify as an EMI option, and the tax advantages will not apply.

Company eligibility conditions

• Gross assets: The company must have gross assets of £30 million or less at the time of grant. For a group, this applies to the gross assets of the whole group.
• Employee headcount: The company (or group) must have fewer than 250 full-time equivalent employees at the time of grant.
• Qualifying trade: The company must carry on a qualifying trade — or be preparing to do so. Several trades are excluded, including financial activities, property development, farming, running a hotel or nursing home, and the operation of certain leasing activities. The excluded trades list catches more companies than founders often expect.
• Independent: The company must not be a 51% subsidiary of another company, and must not be under the control of another company. EMI can work through a holding company structure, but the rules require careful analysis — see the section below.
• UK permanent establishment: The company must have a UK permanent establishment. Non-UK companies cannot grant EMI options.

Employee eligibility conditions

• Working time: The employee must be committed to working for the company for at least 25 hours per week, or — if less — at least 75% of their working time. This catches consultants, portfolio workers and non-executive directors, who generally cannot hold EMI options.
• Shareholding limit: The employee must not hold more than 30% of the ordinary share capital of the company (including shares held by associates) at the time of grant.
• Employee of the company: The option holder must be an employee — not a self-employed contractor or a director who is not also an employee.

Per-option limits

• The maximum value of unexercised EMI options any single employee can hold at any time is £250,000 (measured at the market value at the time of grant).
• The total unexercised EMI options across all employees in a company cannot exceed £3 million (again by reference to market value at grant).

The HMRC Valuation — What It Is and Why It Matters

One of the most important steps in setting up an EMI scheme is agreeing the market value of the shares with HMRC before any options are granted. This is not a legal requirement — an EMI option can technically be granted without a prior HMRC valuation — but in practice, virtually every properly advised EMI scheme includes one.

The reason is straightforward. The tax treatment of EMI options depends critically on the relationship between the exercise price (what the employee pays for the shares when they exercise) and the market value at the date of grant. If the exercise price equals or exceeds the market value at grant, there is no income tax charge at exercise. If HMRC later disputes the market value at grant and concludes it was higher than the price used, an income tax and NIC charge can arise on the difference — turning a capital gain into an income tax liability.

What the HMRC valuation process involves

HMRC operates a Share Valuation team that provides advance market value confirmation for EMI purposes. The process involves:

• Submitting a valuation request to HMRC’s Share Valuation team, setting out the proposed methodology and the supporting information
• Providing financial information: the most recent statutory accounts, management accounts, financial projections, and a description of the business and its prospects
• Setting out any relevant comparable transactions, investment rounds or other evidence that supports the proposed value
• Agreeing a figure with HMRC — once agreed, this is binding for 90 days, within which the options must be granted

Valuation methodology — what HMRC looks at

For early-stage companies without a market-derived value, HMRC’s Share Valuation team typically considers:

• Net assets: The value of the company’s net assets, adjusted for any intangibles that are not on the balance sheet
• Earnings-based methods: Maintainable earnings or EBITDA, multiplied by a relevant sector multiple
• Discounted cash flow: For companies with longer-term financial projections, a DCF model using an appropriate discount rate
• Recent investment rounds: If the company has recently raised equity at an agreed price, HMRC will typically use that price as the starting point for market value
• Minority discount: Where the option pool represents a small percentage of the company, HMRC may apply a minority discount — often 15–25% — to reflect the lack of control and liquidity attached to a minority interest

An experienced Finance Director will build the valuation submission to HMRC in a way that is both technically robust and commercially realistic — supporting the lowest defensible market value (which maximises the tax efficiency for employees) while providing HMRC with the information it needs to agree the figure promptly.

Setting Up the EMI Scheme — The Process Step by Step

An EMI scheme involves three professional parties working together: solicitors (who draft the option agreements and scheme rules), accountants or tax advisers (who may advise on valuation and tax structuring), and the company’s Finance Director (who owns the internal process, the cap table modelling and the HMRC submission timeline). Here is how the process runs end-to-end.

Step 1 — Confirm company and employee eligibility

Before any external advisers are engaged, the FD or CFO should run a preliminary eligibility check: gross assets against the £30m threshold, headcount against 250, the qualifying trade analysis, and the corporate structure. For each proposed option holder, working time and shareholding limit checks. This initial screen takes hours, not weeks, and avoids the situation where legal and valuation work is done for a scheme that turns out not to qualify.

Step 2 — Design the option pool and vesting terms

Before the legal documents are drafted, the company needs to decide on the option pool — how many shares are available, what percentage of the fully-diluted share capital the pool represents, and how it will be allocated between participants. The Finance Director models this against the existing cap table, including the dilutive impact of the option pool on existing shareholders, and tests the economics of different pool sizes and vesting scenarios. Typical EMI vesting schedules are three to four years with a one-year cliff, but the terms can be customised to reflect performance conditions, role-specific milestones or other commercial requirements.

Step 3 — Instruct solicitors to draft the scheme documents

The solicitors produce the EMI scheme rules — the legal framework governing how options work, what happens on exit, what triggers early exercise, and how leavers are treated — and the individual option agreements for each participant. The Finance Director reviews these documents against the commercial terms agreed in step 2 and ensures they are consistent with the cap table model and the intended economics of the scheme.

Step 4 — Submit the HMRC valuation request

The FD prepares and submits the valuation pack to HMRC’s Share Valuation team: accounts, management information, financial projections, a description of the business and its prospects, and the proposed valuation methodology with supporting evidence. HMRC’s published turnaround is around two months, though complex cases or those with missing information take longer. The FD manages the submission, responds to HMRC’s queries and agrees the final value.

Step 5 — Grant the options within 90 days

Once HMRC confirms the market value, the option agreements are signed and the options are granted. The FD ensures this happens within the 90-day window and that the grant documentation is correctly executed and filed in the company’s statutory records.

Step 6 — Notify HMRC within 92 days of grant

This is the step most commonly missed by first-time EMI schemes. Within 92 days of the date on which the first EMI option is granted, the company must register the scheme with HMRC and submit the option grant notification through HMRC’s Employment Related Securities (ERS) online service. Miss this deadline and the options do not qualify as EMI options — the tax advantages are lost, and the only remedy is to regrant, which requires a new valuation and restarts the clock.

The Finance Director’s Role — Beyond Setup

The most common misconception about EMI is that the Finance Director’s involvement ends once the scheme is set up and the 92-day notification is filed. In practice, EMI requires active ongoing management — and the consequences of getting it wrong are borne by the employees who lose their tax reliefs, not just the company.

The annual ERS return

Every company with an active EMI scheme must file an Employment Related Securities (ERS) annual return with HMRC by 6 July each year, covering all option grants, exercises, lapses and other events that occurred in the previous tax year (ending 5 April). The return must be filed even if nothing happened during the year — a nil return is required to keep the scheme registered.

The ERS return is filed through HMRC’s online ERS service and must report each option holder, the terms of their options, any grants made during the year, and any exercises or lapses. Miss the filing deadline and HMRC will issue an automatic penalty — currently £100 for late filing, rising for extended delays. The Finance Director owns this deadline and the filing process.

Monitoring for disqualifying events

A disqualifying event is anything that causes an EMI option to lose its qualifying status. Once a disqualifying event occurs, the affected options must be exercised within 90 days to retain the favourable tax treatment — after which they become unapproved options and the full income tax and NIC charge applies on exercise.

The most common disqualifying events are:

• The company ceasing to qualify: Breaching the gross assets limit (£30m), exceeding 250 employees, or ceasing to carry on a qualifying trade — for example, by acquiring a subsidiary that carries on an excluded trade.
• The employee ceasing to meet the working time requirement: An employee dropping below 25 hours per week — for example, moving to part-time, taking extended leave, or taking on multiple other commitments — triggers a disqualifying event for their options.
• A change of control: If the company is acquired, the options may be affected depending on the terms of the acquisition. A qualifying exchange of shares — where EMI options are rolled over into options over acquiror shares — preserves the tax treatment, but only if the correct steps are followed.
• Variation of option terms: Changing the terms of the option agreement — extending the exercise period, changing the exercise price, or altering the vesting conditions — without following the correct procedure can constitute a disqualifying event.

An experienced Finance Director will flag any proposed corporate action, employment change or financial event against the EMI disqualifying events list before it is implemented — not after. This monitoring is a year-round responsibility, not an annual one.

Managing option exercises

When an employee exercises their EMI options — typically on an exit event or at the end of their vesting period — the Finance Director manages the accounting and reporting around the exercise. This includes:

• Calculating the corporation tax deduction the company can claim (the difference between market value at exercise and the exercise price)
• Ensuring the exercise is correctly reported in the ERS annual return
• Providing employees with the information they need to claim Business Asset Disposal Relief on their eventual share sale, including confirmation of the date of grant and the agreed market value at grant
• Managing any PAYE implications where an option does not qualify as EMI at exercise (for example, because of a disqualifying event that was not caught in time)

New grants to employees joining after setup

EMI schemes are not static. As companies grow and hire, new options will be granted to new participants. Each new grant requires the same eligibility checks, uses the current agreed market value (or a fresh valuation if the 90-day window has expired), and must be notified to HMRC within 92 days. The Finance Director manages the pipeline of new grants alongside the annual ERS return cycle.

Common EMI Pitfalls — and How an Experienced FD Prevents Them

Most EMI problems are avoidable. These are the situations FD Capital’s network has encountered most frequently — and what proper finance leadership does to prevent them.

1. Missing the 92-day notification deadline

Options granted without a timely HMRC notification are not EMI options. The fix — regranting — requires a new valuation (likely at a higher value than the original) and resets the clock. In a fast-moving company where share values are rising, the delay can be expensive. An FD with EMI experience treats the 92-day window as a non-negotiable compliance milestone with a target submission date four weeks before the deadline.

2. Granting options to non-qualifying employees

Consultants, contractors, part-time workers below the 25-hour threshold, and employees who already hold more than 30% of the shares cannot hold EMI options. Granting options to someone who does not qualify means those options are not EMI options — with the same outcome as a missed notification. The eligibility check must be done at grant, not assumed from job title.

3. Exceeding the £250,000 per-employee limit

This happens most often in companies with rising valuations where early option grants were small but subsequent grants to the same employee push the total above the limit. The Finance Director tracks the cumulative market value of each employee’s outstanding options — at grant date values — and alerts management before any new grant would take an individual over the limit.

4. Disqualifying events that go unnoticed

The most common scenario is an employee reducing their hours — going part-time, taking a period of extended leave, or taking on substantial external commitments — without the HR or finance function flagging the EMI implications. A company undergoing rapid growth is also at risk of breaching the 250-employee headcount limit without realising the impact on existing option holders. The Finance Director monitors both.

5. Not coordinating EMI with a fundraising round

A new investment round at a significantly higher valuation resets the market value of shares, which affects any EMI grants made after that round. Companies that raise investment and then try to grant EMI options face a higher exercise price — reducing the economic value of the options to employees. Timing grants to occur before a round, or structuring the round in a way that minimises the valuation impact on the EMI pool, is something an experienced FD plans proactively rather than reacts to after the fact. This connects directly to EIS and SEIS fundraising planning — see our guide to EIS and SEIS fundraising for the context on how equity rounds interact with employee incentive schemes.

EMI and Business Asset Disposal Relief — The Tax Outcome at Exit

The tax outcome at exit is the point at which the value of getting EMI right — or the cost of getting it wrong — becomes fully visible. When an employee exercises qualifying EMI options and sells the resulting shares, the gain is subject to capital gains tax rather than income tax, and if the conditions for Business Asset Disposal Relief (BADR) are met, that CGT rate is 10% (rising to 14% from 6 April 2025 and 18% from 6 April 2026 under the October 2024 Budget changes).

For an employee with £500,000 of gain, the difference between paying 10% CGT (£50,000 tax) and 45% income tax plus NIC (up to £225,000 tax) is the entire proposition of EMI. That difference is only available if the options were properly set up and maintained as qualifying EMI options throughout their life.

BADR conditions for EMI option holders

Post-exercise, the shares must be held for at least 24 months to qualify for BADR (the shares holding period, not the option holding period). For exit scenarios where shares are sold immediately on exercise — which is typical in a trade sale — HMRC has a special rule that allows the option holding period to count towards the 24 months, provided the options were granted at least 24 months before the sale. This is another reason why timing of the initial EMI grant matters: companies that grant options shortly before a sale may find that employees miss the BADR qualification period.

How FD Capital Places EMI-Experienced Finance Directors and CFOs

Designing and running an EMI scheme is a specific finance skill set. It sits at the intersection of tax, legal structuring, cap table management, HMRC relationship management and HR. Not every Finance Director or CFO has done it — but for a growth company putting equity incentives in place for the first time, the difference between someone who has and someone who has not is significant.

FD Capital has placed Finance Directors and CFOs with UK growth companies across technology, SaaS, fintech, life sciences and professional services — many of whom have set up and managed EMI schemes from scratch, navigated HMRC valuation negotiations, managed disqualifying event risks and run the annual ERS return cycle year after year. We know what the role requires and we match companies with candidates who have done it before.

We place across all engagement models. A Fractional Finance Director for a company that needs the EMI scheme set up properly but does not yet have the volume to justify a full-time FD. An Interim CFO for a business approaching an exit where the EMI compliance history needs to be reviewed and any gaps resolved before a buyer’s due diligence team looks at it. A Permanent Finance Director for a company scaling rapidly where the option pool is being actively used and the annual compliance cycle is a substantive internal task.

Our related pages on Finance Directors for Startups, SaaS CFO Recruitment, and Technology Finance Directors cover the sectors where EMI is most actively used.

EMI Scheme Support: From Initial Setup to Annual Compliance and Exit

Whether you are setting up an EMI scheme for the first time, reviewing an existing scheme ahead of a funding round or exit, or resolving a compliance issue before it affects your employees’ tax treatment, FD Capital can place a Finance Director or CFO with the specific experience your situation requires. We will work with you to understand the scope of what is needed and introduce candidates who have done this — in your sector, at your stage — before.
