Enterprise Management Incentive (EMI) share option schemes have long been one of the UK’s most attractive tools for rewarding and retaining key employees. Designed with high-growth companies in mind, EMI offers a tax-efficient way to give employees a stake in the future success of the business.
Significant reforms are on the horizon. Following the Autumn Budget 2025, the UK government is introducing the most substantial expansion of EMI in over two decades, with changes taking effect from April 2026 and beyond.
This article explores how EMI schemes work, why they matter, and what the upcoming changes mean for businesses and employees.
What is an EMI share option scheme?
An EMI scheme allows qualifying companies to grant selected employees the option to acquire shares at a fixed price in the future. These options are typically exercised on an exit event (such as a sale) or after a vesting period.
The key advantage lies in the tax treatment. When structured correctly:
- no income tax or National Insurance is typically payable on exercise
- gains are usually subject to Capital Gains Tax instead of payroll taxes
- business Asset Disposal Relief may reduce the effective tax rate further
As a result, EMI schemes are widely used by SMEs to align employee incentives with long-term growth.
Why EMI matters
EMI schemes have become a cornerstone of UK SME reward strategies. They help businesses:
- attract high-quality talent without relying solely on cash salaries
- retain key employees through long-term incentives
- align employee and shareholder interests
- compete globally for skilled workers
Before the changes in April 2026, EMI schemes were restricted to companies with:
• maximum 250 employees
• gross assets capped at £30 million
• total option grant value limited to £3 million
While suitable for many SMEs, these thresholds often excluded companies just as they began to scale. Many businesses “grew out” of EMI and had to switch to less tax-efficient alternatives.
The 2026 reforms: a major expansion
From 6 April 2026, the government is significantly expanding access to EMI schemes.
Key changes
1. Increased company size limits
FTE employee limit doubles from 250 to 500
Gross asset threshold rises from £30 million to £120 million
2. Larger option pools
Company-wide option grant value limit increases from £3 million to £6 million
3. Longer exercise window
Maximum exercise period extended from 10 to 15 years (this change can be applied retrospectively to existing options)
These changes will allow many SMEs to qualify for EMI for the first time or bring high growth companies back within the limits.
What do these changes mean for businesses?
The reforms represent a shift in how EMI is positioned within the UK tax landscape.
1. More companies will qualify
Businesses that previously exceeded the limits may now be eligible again.
2. Greater flexibility in structuring incentives
Larger option pools and longer exercise periods enable more sophisticated reward strategies.
3. Better alignment with growth timelines
A 15-year exercise window reflects the longer journey to exit many modern companies experience.
4. Strategic planning opportunities
Companies should consider whether to:
- introduce EMI for the first time
- replace existing non-tax-advantaged schemes
- amend current EMI options to extend their lifespan
What should you do now?
If you are thinking about putting in place a share option scheme or have one in place already, we suggest you:
- review eligibility under the new thresholds
- assess existing share plans and whether EMI could replace them
- plan new grants to take advantage of the expanded limits
- consider amending existing options to benefit from the extended exercise period
Final thoughts
The upcoming EMI reforms mark a significant evolution of the UK’s flagship employee share scheme. By widening access and increasing flexibility, the government is clearly aiming to support scaling businesses and strengthen the UK’s entrepreneurial ecosystem.
For many companies, EMI will no longer be something they outgrow—it will become a long-term incentive tool that evolves alongside them.
