SAYE Sharesave and Share Incentive Plans: A Guide for Employees and International Movers

All-employee share schemes offer a tax-efficient route for employees to build equity in the businesses they work for, without the complexity of EMI or CSOP. The two main HMRC-approved all-employee schemes — Save As You Earn (SAYE, commonly called Sharesave) and the Share Incentive Plan (SIP) — are open to all eligible employees on similar terms and carry meaningful tax advantages when operated correctly. For internationally mobile employees, the rules around departure from the UK add a further layer of planning.

Save As You Earn (SAYE / Sharesave)

How SAYE Works

Under a SAYE scheme, the employer grants employees an option to buy company shares at a fixed price, up to a 20% discount to the market value on the grant date. The employee simultaneously enters a certified savings contract — effectively a regular savings arrangement — with a bank or building society approved by HMRC. Contributions are deducted from net pay, after tax and NIC.

Savings contracts run for three or five years. The savings (plus any bonus, which is now rare given low interest rates) are used to exercise the option at the end of the contract period. The employee may also withdraw from the scheme early without penalty, receiving back their contributions, but the option lapses.

Contribution limits: Employees may save between £5 and £500 per month (the upper limit was doubled from £250 to £500 from April 2014).

Tax Treatment

The discount built into the option price (up to 20%) is not subject to income tax or NIC when the option is granted or exercised. This is the key advantage of SAYE: the employee acquires shares at a below-market price without any income tax consequence.

On exercise: No income tax, no NIC. The option is exercised at the contractual price; any discount to market value at that point is tax-free.

On sale: Any subsequent gain (proceeds minus market value at exercise) is a capital gain. There is no BADR entitlement for SAYE shares on the same basis as EMI, but the annual CGT exempt amount applies (£3,000 for individuals as at 2026–27). If the shares are transferred to an ISA within 90 days of exercise, the future growth and income within the ISA is tax-free.

NIC-free payroll deductions: The monthly savings are made from net pay — NIC is not charged on contributions, as they are deductions rather than benefits.

The 20% Discount in Practice

The discount means employees can make a guaranteed profit on exercise, provided the share price at exercise is at or above the price on grant date. If the share price falls below the option price, the employee simply does not exercise and gets their savings returned in full. SAYE is sometimes described as a "no-lose" scheme — though the opportunity cost of locking savings for three to five years is real.

Example: option price £8.00 (20% below £10.00 market price at grant). After three years, if shares trade at £15.00, the employee exercises, acquiring shares worth £15.00 for £8.00. The £7.00 per share spread is entirely free of income tax and NIC.

Share Incentive Plans (SIP)

SIPs operate on a fundamentally different basis from SAYE. Rather than granting options, SIPs involve the employer allocating actual shares into a trust for the employee's benefit. There are four distinct elements, which companies may operate separately or in combination:

Free Shares

Employers may award up to £3,600 of free shares per employee per tax year, based on performance targets or simply as part of the remuneration package. Free shares must be offered to all eligible employees on similar terms (though performance metrics may vary). They are held in the SIP trust for a minimum holding period of between three and five years (employer's choice). If held for five years, no income tax or NIC is payable on the award; gains on sale are subject to CGT. If released earlier, income tax and NIC apply to the market value at release.

Partnership Shares

Employees may buy partnership shares out of pre-tax, pre-NIC pay — up to £1,800 per year (or 10% of salary if lower). Shares are purchased in the market and held in trust. No income tax or NIC on the purchase. If the shares are withdrawn within three years, income tax and NIC apply on their market value at withdrawal; if withdrawn after five years, no income tax or NIC is due. On sale after withdrawal, gains are subject to CGT. This is a form of salary sacrifice applied to share purchases, effectively increasing the tax efficiency of saving.

Matching Shares

Employers may award matching shares — up to two matching shares for every partnership share purchased. Matching shares are subject to the same holding period rules as free shares. A two-to-one match is a powerful incentive: the employee buys one share from pre-tax salary and receives two additional shares at no cost.

Dividend Shares

Dividends paid on SIP shares may, at the employer's election, be reinvested within the plan in dividend shares. No income tax is payable on dividends reinvested as dividend shares; the shares grow the holding on a tax-deferred basis. This is particularly valuable in high-dividend-yield companies.

SIP and ISAs

Shares held in a SIP that have been held for the minimum holding period can be transferred to a Stocks and Shares ISA within 90 days of removal from the plan. This shelters future gains and income from CGT and income tax. The transfer does not count towards the employee's annual ISA subscription limit.

Internationally Mobile Employees: Key Considerations

Leaving the UK — SAYE

If an employee leaves UK tax residence before the end of the SAYE savings contract, HMRC's position is that the options do not automatically lapse. However:

• If the employee exercises the option after leaving UK residence, HMRC will seek to tax the spread (market value minus exercise price) as UK-source employment income — potentially subject to UK income tax on the proportion attributable to UK working days during the option period.
• Many SAYE scheme rules permit "good leaver" early exercise — exercise is permitted within six months of leaving the employer (for reasons such as redundancy, retirement, serious illness, or TUPE transfer). Exercise within this window while still UK resident preserves the income tax-free treatment.

For employees who know they are relocating, the six-month early exercise window is critical. Financial planning should account for the need to fund the exercise price from the accumulated savings contract (which may also need to be closed early) and the investment decision regarding what to do with shares acquired at a discount.

Leaving the UK — SIP

SIP shares held in the trust when an employee ceases UK residence:

• Free and matching shares released within three years (or, under some schemes, five years) of award will trigger income tax on the market value at release if removed from the plan. The charge applies to UK-source employment income.
• Partnership shares have effectively already been purchased with pre-tax income. On sale after leaving the UK, CGT applies only on UK-situs assets — ordinary UK-listed shares are UK-situs assets and gains may be taxed in the UK for non-residents where the property is UK-situated. However, for employees leaving to treaty countries, double tax treaty relief will generally apply to exempt from UK CGT.

Arriving in the UK

Employees arriving in the UK who hold existing SAYE or SIP-equivalent schemes from a prior employer in another jurisdiction should take advice before taking up UK residence. The UK does not provide a "clean break" for pre-arrival equity grants — UK tax will apply on the UK-source proportion of any gains realised post-arrival. The new Foreign Income and Gains (FIG) exemption (for first four years of UK residence from April 2025) does not exempt share scheme income attributable to UK working days.

Source Rules for Mobile Employees

For employees who worked partly in the UK and partly overseas during the option period, HMRC applies sourcing rules to determine the UK-taxable proportion. The standard approach is a time-apportionment: the number of working days in the UK during the option period divided by total working days. This can produce complex results for executives who move frequently.

Employer Considerations

For employers designing all-employee schemes, SAYE and SIP are complementary rather than competing. SAYE is better suited to companies where share price appreciation is expected — the option structure amplifies the upside while protecting savings. SIP is better suited to current-income delivery and companies wanting to create immediate share ownership without the option complexity.

Both schemes require HMRC registration. SIPs require an approved plan trust and a qualifying SAYE savings carrier for SAYE. Scheme rules must be drafted to comply with ITEPA 2003 Schedule 2 (SIP) and Schedule 3 (SAYE). HMRC must be notified of any scheme amendments.

Compliance Caveat

Tax rules for employee share schemes change regularly. SAYE savings contract bonus rates, ISA subscription limits, CGT rates, and sourcing rules for mobile employees are all subject to amendment in Finance Acts. This guide reflects the position as at June 2026. Internationally mobile employees in particular should take specialist advice before exercising options or moving shares between plans across jurisdictions. The interaction of UK tax with US tax (for US citizens) or the tax law of other home countries can create double taxation risks that require early planning.
