Employee share schemes: how do they work?

Your employer does not have to give you shares, and an option is not a share. If you have been offered one, ask today for the plan rules, the award notice, what you must pay and the date the offer or option expires. A care worker, shop assistant or warehouse picker should not have to guess whether a promised stake is real, affordable or still yours if you leave.

Personal shares or collective ownership?

With direct ownership, you acquire a personal holding. Shares may carry voting rights and dividends, but the share class and company articles decide. An option is a right to buy shares at an agreed price. You do not become a shareholder merely by receiving it. SIP shares are held in a trust for you; SAYE, CSOP and EMI give you options.

With indirect ownership, an Employee Ownership Trust, or EOT, holds a controlling stake for employees as a group. You do not get an individual slice to sell. Employee representation and bonuses depend on how the company and trust are run. Neither a yearly bonus nor a seat on the board follows automatically.

A company can combine an EOT with a personal share plan, if it meets the conditions for both. Check the award documents as well as your employment contract. A promise of equity in a job offer is not enough to tell you what rights you will receive.

The four tax-advantaged schemes

The four tax-advantaged schemes have specific rules under the Income Tax (Earnings and Pensions) Act 2003. Their tax relief depends on meeting those rules. The employer chooses which plan to offer, if any. You cannot insist on EMI simply because its tax treatment would suit you.

SIP: free, bought and matched shares held by a trust

A Share Incentive Plan uses a UK-resident trust to hold shares for you. Your employer can give up to £3,600 of free shares per tax year. You can buy partnership shares from pre-tax salary, up to £1,800 or 10% of your income for the tax year, whichever is lower. The employer can add up to two matching shares for each partnership share. Some plans also reinvest dividends in dividend shares.

Keep free, partnership and matching shares in the plan for five years and you pay no income tax or National Insurance contributions, or NICs, on their value. Dividend shares have a separate three-year income tax rule. Each award has its own clock; joining the plan five years ago does not make last month’s shares tax-free.

Early withdrawal can trigger tax. For free and matching shares, the taxable amount is their market value on leaving the plan before three years, or the lower of award value and exit value between three and five years. For partnership shares, the normal charge before three years is also based on exit value; between three and five years it is the lower of the salary used to buy them and exit value. Special rules apply to certain compulsory sales. NICs may also apply. Statutory exceptions protect certain leavers, including those leaving through redundancy, injury, disability, retirement or death.

You pay no Capital Gains Tax, or CGT, if the shares stay in the SIP until sale. If you take them out and sell later, CGT generally applies to growth after removal. A qualifying ISA transfer within 90 days of removal avoids CGT. Pension transfers have different conditions. A direct transfer when the scheme ends can be exempt; a later transfer within 90 days can still create CGT on intervening growth.

SAYE: save monthly, buy at a fixed price

SAYE, also called Sharesave, links an option to a savings contract. You save up to £500 a month for three or five years. The company fixes the option price at the start. It can be up to 20% below the shares’ market value then, although not every plan offers that discount.

1. Save monthly. Contributions come from take-home pay. Interest and any savings bonus under the qualifying contract are tax-free.
2. Choose at maturity. Use your savings to buy shares at the option price, or take back the cash. You do not have to exercise an option that would cost more than the shares are worth.
3. Check tax before selling. Qualifying exercise carries no income tax or NICs on the discount or growth. A sale can create CGT. A qualifying ISA transfer within 90 days of exercise can avoid it, subject to the ISA subscription limit. Do not assume a pension transfer has the same treatment.

SAYE must be offered to qualifying employees on similar terms. A qualifying service period of up to five years is allowed. Check the savings commitment against your budget, especially if your pay may change.

CSOP: options for selected staff

A Company Share Option Plan lets the employer select participants. It is available more widely than EMI, including to companies outside EMI’s size or trading rules. The exercise price must be at least market value at grant. Since 6 April 2023, the individual limit is £60,000 of shares under unexercised CSOP options, valued at grant. It was previously £30,000.

Normally, exercise between three and ten years after grant carries no income tax or NICs. Some earlier exercises qualify, including in specified leaver or takeover circumstances. Exercise outside the tax-relieved rules can create income tax and, where applicable, NICs. CGT can apply when you sell.

EMI: options for eligible trading companies

Enterprise Management Incentives let eligible companies offer options to selected employees. For grants from 6 April 2026, the company limits are fewer than 500 full-time-equivalent employees, gross assets no more than £120 million and unexercised EMI options over shares worth no more than £6 million at grant. The company must meet independence and trading conditions. Excluded trades include banking, farming, property development, legal services and shipbuilding. The Northern Ireland exception is explained below.

You must work at least 25 hours a week for the company or group, or at least 75% of your total working time. The individual limit is £250,000, valued at grant, with a further three-year restriction on new qualifying grants once that maximum has been reached. This is not a fresh £250,000 allowance every year.

The maximum tax-qualifying exercise period increased to 15 years from 6 April 2026. Existing options that have not expired or been exercised can also be amended under the statutory rules. Your agreement’s deadline does not automatically become 15 years.

On qualifying exercise, no income tax or NICs is normally due if the exercise price was at least market value at grant. A discount at grant can create an income tax charge, with NICs where applicable. Loss of eligibility can also change the tax result, so the grant price alone does not guarantee relief.

On sale, growth is generally within CGT. EMI shares can qualify for Business Asset Disposal Relief, or BADR, without the usual 5% shareholding test. The option must have been granted at least two years before sale, and the other qualifying conditions still matter. For disposals from 6 April 2026, BADR is 18%, with a £1 million lifetime limit on qualifying gains.

Employee ownership trusts: owning together

An EOT holds a controlling interest for employees as a whole. This means more than 50% of the ordinary share capital and voting power, with the required rights to profits and assets. The trust buys the shares from existing owners. The company may fund that purchase from its profits, including payments over time. You do not personally receive shares just because your employer becomes EOT-owned.

A qualifying EOT-controlled company can pay bonuses of up to £3,600 per employee per tax year free of income tax, but not NICs. This is a tax exemption, not a promise that your employer will pay the maximum. The company and bonus scheme must meet the qualifying conditions.

Qualifying employees must participate on the same terms, but that does not require identical amounts. Permitted factors include pay, service and hours worked. For payments from 30 October 2024, directors can be excluded without breaching the participation requirement.

The sellers’ relief is separate from your bonus exemption. For disposals on or after 26 November 2025, 50% of the sellers’ gain is chargeable and 50% is held over into the trustees’ base cost, if the EOT conditions are met. Before that date, qualifying disposals received full relief. BADR and Investors’ Relief cannot be claimed on the same disposal.

Changes effective from 30 October 2024 require UK-resident trustees, prevent former owners and connected people from retaining control of the trust, tighten safeguards against paying above market value and extend the period in which a disqualifying event can withdraw the sellers’ relief. Trustees must check these conditions before a purchase; a sale to a trust is not automatically an EOT sale.

Unapproved awards: growth shares, free shares and one-off options

Share awards outside the four tax-advantaged schemes are often called “unapproved”. That does not mean unlawful. Ordinary share awards, growth shares, restricted stock units and non-tax-advantaged options can all be used, but their tax treatment differs. Growth shares usually give you a return only above an agreed value threshold. A restricted stock unit is a promise of a future award, not necessarily shares you own today.

You may pay income tax when shares are acquired or an option is exercised. PAYE and employee and employer NICs can apply where shares are readily convertible assets, including where arrangements exist for selling them. Later growth in shares you own can create CGT. A cash-settled phantom award gives you cash linked to share value, not ownership; do not treat it as a share sale with CGT relief.

For restricted shares, you and the employer can make a section 431 election within 14 days of acquisition. A full election taxes the acquisition using unrestricted market value and removes later restricted-securities charges under that part of the legislation. It can increase your upfront tax bill. It does not turn every future payment into a capital gain. Get the valuation and election advice before accepting the shares, not after the deadline.

The employer must also check its annual ERS reporting obligations, with returns due by 6 July after the tax year. Ask whether the award agreement makes you bear employer NICs as well as your own tax. For payroll treatment, see tax on employee benefits and employer National Insurance.

Leaving, selling and getting bought out: what happens to your shares

Ask for the plan rules and your award notice before you resign or accept a buyback. Read the plan rules, option agreement and company articles together; a “good leaver” label is not a universal legal definition. Find out what the plan lets you keep and whether the tax relief survives.

1. Find the leaving clause. Ask whether resignation, redundancy, ill health, retirement or dismissal changes your entitlement. Some plans let certain leavers retain awards; others require a sale or cancel options.
2. Get the exact deadline in writing. Vesting means meeting the conditions to earn an award or exercise it. Unvested options may lapse when you leave. There is no single exercise deadline for all schemes. Ask the administrator for your last exercise date today, and do not assume the 15-year EMI maximum changes your agreement.
3. Read the sale restrictions. Pre-emption provisions may require you to offer shares to existing holders first. A drag-along clause can require a minority holder to join a sale. Check who sets the price and whether a leaver must sell at market value, cost or another amount.

SIP has statutory early-withdrawal exemptions for qualifying leavers, as explained above. With SAYE, you may be able to recover your savings or exercise early, depending on why and when you leave. For EMI and CSOP, permission to keep an option is not itself confirmation that exercise will still be tax-relieved. Ask the administrator for both the contractual deadline and the tax position. If you are in a union, contact your rep before agreeing to surrender or transfer shares; Unite, USDAW and UNISON represent workers across hospitality, retail and care. Acas early conciliation, Citizens Advice and a law centre can help with a related employment dispute. Ask Acas promptly about any claim deadline.

Owning shares does not remove your ordinary employment rights. The separate employee shareholder status discussed below is an exception. If your dismissal or redundancy is disputed, check unfair dismissal eligibility and redundancy pay as well as the award documents.

Do you have to join? Can the terms change?

You do not have to buy shares or accept an option. SIP and SAYE participation is voluntary; selective awards are offers too. Once you accept, the award documents govern contributions, vesting and forfeiture. An employer’s discretion to change a plan is not the same as an unlimited right to disregard an existing award.

Your employer needs your agreement to deduct salary for partnership shares. Before joining, ask which share class you will receive, whether you can sell and how new share issues could dilute your percentage holding. For differences between staff, see whether different benefits are lawful. For representation, see how employees can be heard.

Employee shareholder status: the “shares for rights” deal

Ordinary share participation does not require you to surrender employment rights. A different arrangement, introduced on 1 September 2013 under section 205A of the Employment Rights Act 1996, does. An employee shareholder receives at least £2,000 of fully paid shares in exchange for giving up certain rights, including ordinary unfair dismissal protection and statutory redundancy pay. The arrangement also restricts flexible-working and training requests and changes notice for early return from maternity or adoption leave to 16 weeks.

The safeguards matter. You must receive a written statement of the status and share rights, then independent advice on the agreement’s effect. Seven days must pass after the day you receive that advice before the agreement can take effect. The company must meet reasonable advice costs even if you decline. Discrimination and automatically unfair dismissal protections are not all signed away.

Tax reliefs were withdrawn for shares issued on or after 1 December 2016. The status remains on the statute book in England, Wales and Scotland; it never applied in Northern Ireland. A new agreement does not restore those tax breaks. If you signed one, get advice on its validity and the rights you still have. A shorter unfair dismissal qualifying period would make ordinary protection available sooner, not make surrendering it less costly.

What to check before you accept

A tax advantage does not make employer shares a safe substitute for cash pay. Your job and investment depend on the same business. Shares can fall in value, and an option can expire without being worth exercising. In a private company, you may have no buyer even when an award has a substantial paper value. Shares are not wages. If your employer withholds pay or makes an unlawful deduction, that is wage theft, not a substitute benefit.

• Ask for the exercise cost, any likely tax and whether you must fund both before you can sell.
• Check whether the valuation is for your share class. Investor shares may have different rights to sale proceeds.
• Find out whether a sale, takeover or new investment changes vesting, exercise deadlines or your percentage holding.
• Keep the grant notice, valuation, plan rules and tax elections. Do not rely on a recruitment slide showing an estimated future payout.

Today, save the offer email and plan documents, then write down the next deadline. If something looks wrong, contact your union, Citizens Advice or a law centre. Use Acas early conciliation for an employment dispute that may go to tribunal. Report a separate minimum-wage underpayment to HMRC; exploitation in a GLAA-regulated sector to the GLAA; a workplace safety risk to HSE; and discrimination to the EHRC. A share-plan disagreement alone is not a minimum-wage or safety complaint.

Scotland and Northern Ireland

The share-scheme tax framework and EOT reliefs apply across the UK, with the EMI exception below. Scottish taxpayers pay Scottish income tax rates on taxable employment income from awards; CGT rates are UK-wide. Employment law is devolved in Northern Ireland, so do not apply Great Britain’s dismissal rules there.

A specified Northern Ireland company registered there and trading in goods or electricity retains the earlier EMI limits under the subsidy-control exception. These are £3 million of company options, £30 million gross assets, fewer than 250 full-time-equivalent employees and a ten-year exercise period. This is not an exclusion of every employer with staff in Northern Ireland. See employment law in Northern Ireland.

Changes in force and the next scheduled reform

1. 6 Apr 2024EMI notification deadline changes

   For grants from this date, notification is due by 6 July after the tax year ends, rather than within 92 days.

2. 30 Oct 2024EOT conditions tighten

   Changes include UK trustee residence, restrictions on former-owner control and safeguards on purchase price. Bonus schemes can exclude directors.

3. 26 Nov 2025EOT sellers’ relief reduces

   For qualifying disposals from this date, half the gain is chargeable and half held over.

4. 6 Apr 2026EMI expands and BADR rises to 18%

   The expanded EMI company limits apply to eligible new grants. The maximum exercise period rises to 15 years, with provision to amend eligible existing options. Specified Northern Ireland companies retain the old limits.

Questions people ask

How much tax do you pay at grant, exercise and sale?

An option grant usually carries no immediate tax. At acquisition or exercise, the award’s scheme and conditions determine income tax and NIC relief. At sale, the main CGT rates for 2026-27 are 18% and 24%. The £3,000 annual exempt amount covers your gains across investments, not each scheme separately. SIP sales within the plan and qualifying SIP or SAYE ISA transfers have specific exemptions.

Can your employer take the shares back?

An enforceable forfeiture or compulsory-transfer clause may allow it. Get the clause and valuation method before resigning or accepting a buyback. Cancelling unvested options is different from requiring you to transfer shares you already own.

What happens to SAYE if the share price falls?

At maturity, you can take your savings and any qualifying interest or bonus instead of buying shares. If you exercise and keep the shares, their value can fall afterwards. The cash-or-shares choice does not protect shares once you own them.

Can part-time staff receive EMI options?

Yes, if the working-time test is met. You need at least 25 hours a week for the company or group, or at least 75% of your total working time. Part-time status alone does not disqualify you.

Do you own shares because your employer has an EOT?

No personal holding arises merely from being a beneficiary. Trustees hold the controlling interest for employees collectively. You may receive a qualifying bonus, but £3,600 is the annual income tax exemption limit, not a guaranteed payment.

Can self-employed contractors join an employee scheme?

Providing services as a self-employed contractor does not meet these schemes’ employment conditions. You can be offered shares or options outside them. Ask about the award’s tax treatment rather than assuming every eventual receipt is a capital gain.
