EMI Share Options: Qualifying Conditions, the 2026 Limit Increases & HMRC Challenges

Enterprise Management Incentive options are the most tax-efficient way for a growing company to reward key staff with equity, and the 6 April 2026 limit increases make them available to a much larger pool of companies. The relief is also unusually easy to lose after grant, through a missed notification deadline or an overlooked disqualifying event.

What EMI Options Are and Why They Matter

Enterprise Management Incentive options are a form of tax-advantaged employee share option specifically designed for smaller, growing trading companies that need to compete for talent without the cash resources of a larger employer. Where the scheme's conditions are satisfied throughout, no income tax or National Insurance generally arises on the grant or exercise of the option (provided the exercise price is set at or above market value at grant, or, where set lower, subject to income tax on the discount), and the eventual gain on sale of the shares is instead taxed as a capital gain, often at a lower effective rate than the income tax and National Insurance that would otherwise apply to an equivalent cash bonus or unapproved share award.

Company-Level Qualifying Conditions

The company whose shares are the subject of the option must satisfy several conditions. It must carry on a qualifying trade wholly or mainly in the UK on a commercial, profit-making basis, and must not, to a substantial extent, carry on excluded activities, a list that covers areas such as dealing in land, financial activities, and the provision of legal or accountancy services, among others. The company must be independent, meaning it is not a subsidiary of, or controlled by, another company, other than in limited permitted circumstances such as certain holding company structures for a qualifying trading group.

The 6 April 2026 Limit Increases

For options granted on or after 6 April 2026, the company-level thresholds have increased substantially compared with the position for earlier grants.

• Employee count: the company or group must have fewer than 500 full-time equivalent employees at the time the option is granted, increased from the previous limit of 250.
• Gross assets: the company or group must not have gross assets exceeding £120 million, increased from the previous limit of £30 million.
• Total option pool: the total value of shares under unexercised qualifying EMI options across the whole company must not exceed £6 million, increased from the previous limit of £3 million.
• Exercise period: options granted on or after 6 April 2026 have a 15-year exercise window, extended from the previous 10-year period for earlier grants.

Employee and Individual Conditions

Not every employee can be granted EMI options, and there are limits on how much any one employee can hold. The employee must work for the company for at least 25 hours a week or, if less, at least 75% of their total working time, which can be a genuine obstacle for part-time hires, non-executive advisers, or founders with significant outside commitments. The employee must not, together with associates, hold a "material interest" in the company, generally more than 30% of the ordinary share capital, which can be a relevant constraint for early co-founders as much as external hires. Each employee may hold qualifying EMI options over shares with an unrestricted market value of no more than £250,000 at the date of grant, counting any other unexercised qualifying EMI options they already hold; where a grant would take an individual over this limit, only the excess loses qualifying status, rather than the whole option failing.

Notification Requirements

Each grant of EMI options must be formally notified to HMRC through the Employment Related Securities online service by 6 July following the end of the tax year in which the grant was made. This is a hard, absolute deadline with essentially no discretion for HMRC to extend it, and a missed notification is one of the single most common, and most entirely avoidable, reasons an option that otherwise met every substantive condition loses EMI status altogether, with the employee then facing income tax and National Insurance on exercise as if the option had never been tax-advantaged at all. Smaller and first-time issuers are disproportionately represented among companies that miss this deadline, often because the grant itself was handled informally without engaging the annual compliance cycle that larger, more experienced issuers have already built into their processes.

Disqualifying Events

EMI qualification is not a one-off test passed at grant; it must continue to be satisfied throughout the life of the option, and a range of events occurring after grant can trigger a "disqualifying event", after which the option generally has only 90 days to be exercised if the employee wishes to retain the favourable tax treatment that had accrued up to that point. Common disqualifying events include the company ceasing to meet the trading or independence requirements, for example through an acquisition or a change in the nature of the business; the employee ceasing to meet the working time requirement, including through a change of role, a reduction in hours, or a period of extended leave; and certain variations to the terms of the option itself. The 90-day exercise window is unforgiving in practice: employees and companies frequently fail to recognise that a disqualifying event has occurred at all, only discovering the consequence when the option is eventually exercised outside the window and HMRC treats it as unapproved.

How HMRC Challenges EMI Treatment

HMRC's challenges to EMI treatment typically focus on one of a small number of recurring issues: whether the company genuinely met the trading requirement throughout the relevant period, particularly for companies with mixed trading and investment activities; whether the working time condition was genuinely satisfied for a particular employee, especially non-executive or part-time participants; whether a disqualifying event occurred and, if so, whether the 90-day exercise window was correctly observed; and whether the annual notification was made correctly and on time. Because these are largely objective, factual and procedural questions rather than matters of judgment, EMI disputes often turn heavily on contemporaneous documentary evidence, working time records, board minutes describing the nature of the business, and the actual notification history with HMRC, rather than on any broader interpretive argument.

Practical Steps

• Confirm the company genuinely qualifies before granting, using the limits in force at the actual grant date. Do not assume the 2026 increases apply retrospectively to earlier grants.
• Diarise the 6 July notification deadline as an absolute, non-negotiable date for every tax year in which any EMI options are granted, and confirm each grant has actually been submitted, not merely drafted.
• Monitor working time and material interest conditions for each option holder on an ongoing basis, not just at the point of grant, particularly where roles, hours or shareholdings change.
• Build a disqualifying event monitoring process into any corporate transaction, restructuring, or change in an option holder's employment terms, given the unforgiving 90-day exercise window.
• Keep the documentary record, board minutes on trading status, working time records, and the notification submission history, since these are what HMRC actually examines in a challenge.
