EMI Share Option Schemes Just Got Their Biggest Expansion Ever — Here's What Changed
The Enterprise Management Incentive scheme has long been the gold standard for UK companies wanting to reward key employees with equity in a tax-efficient way. From 6 April 2026, it just became available to a much wider range of businesses, in what's being described as the largest expansion of the EMI regime since it was introduced.
What an EMI Scheme Actually Is
An EMI scheme is a tax-advantaged share option plan available to qualifying UK trading companies. Employees are granted the right to buy shares at a fixed price in the future, and where the scheme is structured correctly, there's typically no income tax or National Insurance due on either the grant or the exercise of the option. Hold the option for at least two years, and option holders can also access Business Asset Disposal Relief when they eventually sell the shares a meaningful tax advantage that makes EMI one of the most attractive equity incentive tools available to UK businesses.
The Three Limits That Just Doubled or Better
Three of EMI's core eligibility limits changed significantly from 6 April 2026. The gross assets limit the threshold above which a company becomes ineligible rose from £30 million to £120 million. The employee headcount limit increased from fewer than 250 to fewer than 500. And the total value of shares a company can have under unexercised EMI options rose from £3 million to £6 million, calculated using the unrestricted market value of the shares at the time each option is granted.
Together, these changes mean many companies that outgrew EMI in recent years and had to fall back on the more complex, less advantageous Company Share Option Plan instead may now qualify to use EMI again. It's a shift that matters well beyond any single company, since equity incentives like this have become a standard part of how the wider UK startup ecosystem competes for talent against better-funded rivals.
Options Can Now Run Longer
Alongside the eligibility changes, the maximum period over which EMI options can be exercised is increasing from 10 years to 15 years, for options granted on or after 6 April 2026 and in many cases, this extension can also apply retrospectively to existing options that haven't yet expired or been exercised. For companies that are taking longer to reach an exit event than they once expected, that extra runway on the option lifespan gives both the company and its employees more flexibility before a decision has to be made.
The Paperwork Is Getting Lighter Too
The government has also confirmed it intends to relax the strict time limits for notifying HMRC of an EMI option grant, through legislation expected in the Finance Act 2027. Missing that notification window has historically been one of the more common and costly ways companies accidentally lose EMI's tax advantages. Companies will still need to register a new scheme, declare that it meets the relevant conditions, and submit annual returns each year by 6 July, but the easing of the strict notification deadline should reduce a source of compliance risk that's tripped up plenty of well-intentioned companies in the past.
A New Exit Route Worth Knowing About
One more detail is worth flagging for founders thinking ahead to liquidity events: EMI and CSOP contracts granted before 6 April 2028 can now be amended to include the sale of shares on the Private Intermittent Securities and Capital Exchange System as a specified exercise event, while still retaining EMI tax treatment. For companies exploring newer, more flexible routes to giving employees liquidity before a full exit, this closes a gap that previously didn't exist.
What This Means for Founders
If a company was previously excluded from EMI because it had grown past the old asset or headcount limits, it's worth reassessing eligibility now rather than assuming the door is still closed. The scheme remains one of the most tax-efficient ways to attract and retain key employees without committing to large cash salaries, and these changes were specifically designed with the needs of modern, high-growth scale-ups in mind companies that were simply too large for the old rules to make sense.
I came across a breakdown of this in Entrepreneur Plus Magazine, which explained how the changes are bringing a number of previously excluded scale-ups back within the scope of one of the UK’s most valuable employee incentive schemes.
