Employee Share Options (EMI Schemes): A 2026 Guide to Tax, Rules & Updates

The Enterprise Management Incentive (EMI) scheme is the UK’s most tax-advantaged employee share option plan. It allows growing companies to attract, retain, and reward key employees by offering them equity with significant tax benefits. Recent legislative changes have expanded the scheme’s scope, making it a more powerful tool than ever for both start-ups and scaling businesses. This guide explains Employee Share Options and much more.

The Unrivalled Tax Advantages of EMI

The core appeal of an EMI scheme is its exceptional tax efficiency for employees. When structured correctly, the tax treatment is favourable at every stage.

• At Grant: There is no Income Tax or National Insurance liability when a qualifying EMI option is granted.
• At Exercise: Provided the option’s exercise price was at least equal to the market value of the shares at the grant date, no Income Tax or National Insurance is due when the employee exercises the option to acquire the shares.
• At Sale: When the employee eventually sells the shares, the gain is subject to Capital Gains Tax (CGT), not Income Tax. Furthermore, gains on shares acquired through an EMI option often qualify for Business Asset Disposal Relief (BADR), provided certain conditions are met, including a minimum holding period. This significantly reduces the tax payable compared to a cash bonus or non-tax-advantaged share award.

For the company, there is often a Corporation Tax deduction available when the EMI options are exercised. This deduction is generally based on the market value of the shares at the time of exercise, less the exercise price paid by the employee.

What Are the Employee Share Options Qualifying for the Scheme: Company and Employee Rules

To grant qualifying EMI options, both the company and the employee must meet specific criteria set out in the Income Tax (Earnings and Pensions) Act 2003 (ITEPA 2003).

Company Requirements

A company must satisfy several conditions to be eligible, including independence, having only qualifying subsidiaries, and conducting a qualifying trade. The trading activities test excludes certain sectors like banking, property development, and legal services.

Employee Requirements

An employee must meet an employment and working time commitment to be eligible for EMI options. They must not have a “material interest” in the company, which is a test relating to their existing shareholding.

Major Expansion: The New Rules from 6 April 2026

The government has significantly expanded the EMI scheme, with new, more generous limits taking effect from 6 April 2026. These changes are designed to allow larger, scaling companies to access the benefits of EMI.

These changes allow growing companies to continue offering EMI options for longer, supporting their ability to attract and retain high-calibre candidates as they scale. The extension of the exercise period to 15 years can also apply retrospectively to existing, unexercised options, offering greater flexibility.

Employee Share Options Administrative Simplifications

Recent changes have also simplified the administrative process for granting EMI options, reducing the burden on companies.

• Notification Deadline Extended: The deadline for a company to notify HMRC of a grant of EMI options has been extended. Instead of the previous 92-day window, notification is now due by 6 July following the end of the tax year in which the grant was made. This reduces the risk of companies inadvertently missing the deadline and disqualifying the options.
• Working Time Declaration Removed: Companies no longer need to have the employee sign a working time declaration, nor must the company declare this on the grant. This removes an administrative step that was a common source of errors.
• Restrictions in Option Agreement: The requirement to set out full details of any restrictions on the shares within the option agreement itself has also been removed.

These measures collectively make the process of granting options simpler and less resource-intensive for the estimated 4,700+ companies that use the scheme.
