SAYE (Save As You Earn), also known as a Sharesave scheme, is a UK government-approved employee share scheme that allows employees to save regularly and use those savings to buy shares in their employer at a discounted option price. Under a SAYE scheme, employees save between £5 and £500 per month over 3 or 5 years. At the start of the scheme, the employer grants an option to buy shares at a fixed price — typically at a discount of up to 20% below the market price at the grant date. At the end of the savings period, employees can choose to exercise the option and buy shares at the original option price (which may now be well below the current market price), effectively banking a profit. Alternatively, if the share price has fallen below the option price, employees can simply take back their savings plus any bonus (the bonus being the equivalent of 3-5 years of tax-free interest). The key tax advantage is that there is no income tax or National Insurance due when the option is exercised — the profit (the difference between option price and market value) is not subject to income tax if the scheme is HMRC-approved. Any subsequent gain on selling the shares is subject to Capital Gains Tax (CGT). The 2024-25 CGT annual exempt amount is £3,000.
Savings at maturity = monthly saving × number of months; Option profit = (market price at exercise - option price) × number of shares; Shares purchasable = savings / option price
- 1At scheme launch, choose a monthly savings amount between £5 and £500 and a savings term of 3 or 5 years
- 2Your employer grants you an option to buy company shares at the option price, fixed at grant date — typically at up to 20% discount to market price
- 3Each month, savings are deducted from net pay and paid into a special bank account linked to the scheme
- 4At the end of the 3 or 5 year term, you receive your savings back plus a tax-free bonus (set at the start of the scheme)
- 5If the current share price is above the option price, exercise your options — buy shares at the lower option price and either hold or sell
- 6No income tax or National Insurance is charged on the profit at exercise (the spread between option and market price)
- 7If you sell the shares immediately, any gain between the market value at exercise and the selling price is subject to Capital Gains Tax
No income tax on the £6,000 profit at exercise. CGT applies only if shares are held and later sold at a further gain.
The employee has turned £7,200 of savings into £13,200 of shares — a £6,000 gain with no income tax or NI. If sold immediately, any difference from the exercise value is subject to CGT.
If share price falls below option price, the employee never exercises — they simply receive their savings back with the bonus.
The downside is fully protected: the savings are guaranteed regardless of share price. The employee only exercises if the share price is above the option price.
£500/month is the maximum contribution allowed. The profit at exercise is exempt from income tax and NI.
A maximum 5-year scheme with a strong share price performance could generate over £30,000 of income-tax-free profit. However, this is concentrated in one company's shares — significant risk if the employer's stock falls.
Cost basis for CGT is the market value at exercise, not the option price.
After exercise, the CGT cost basis is the market value at the time of exercise. Any further gain on holding the shares before selling is subject to CGT in the normal way.

How much can I save in a SAYE scheme?
You can save between £5 and £500 per month. The savings term is either 3 years or 5 years. The total savings at maturity, including any bonus, are used to buy shares at the option price. This is particularly important in the context of uk share save saye calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk share save saye computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Is there income tax when I exercise my SAYE options?
No. For HMRC-approved SAYE schemes, there is no income tax or National Insurance due when you exercise the option at the end of the savings term. The profit (difference between option price and market value) is entirely free of income tax and NI. This is particularly important in the context of uk share save saye calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk share save saye computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What happens if I leave my employer during the scheme?
If you leave due to death, injury, disability, redundancy, retirement, or certain other qualifying reasons, you can usually exercise the option at a reduced number of shares or take back your savings. Leaving voluntarily forfeits the option but you still receive your savings back. This is particularly important in the context of uk share save saye calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk share save saye computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Can I join multiple SAYE schemes?
You can join a new SAYE scheme each time one is offered (typically annually). However, you can only hold SAYE options granted under different schemes simultaneously — the £500/month limit applies per scheme, not in aggregate. This is particularly important in the context of uk share save saye calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk share save saye computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is the bonus paid at the end of the scheme?
The bonus is the equivalent of a tax-free interest payment on savings held over the 3 or 5 year term. The rate is set by HMRC at the start of each scheme and can be 0% when interest rates are low. The savings bank (typically National Savings or a bank partner) pays the bonus.
What is the tax treatment if I transfer shares into an ISA?
You can transfer shares acquired through a SAYE scheme into a Stocks and Shares ISA within 90 days of exercise. You can do this at no cost — the shares do not use your ISA subscription limit. Future growth and income within the ISA is then completely tax-free. This is particularly important in the context of uk share save saye calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk share save saye computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is the difference between SAYE and Share Incentive Plans (SIPs)?
SAYE is a savings-linked option scheme where you pay a fixed option price set at a discount. SIPs allow employees to buy shares from gross pay (saving income tax and NI) and may include free shares from the employer. Both are HMRC-approved but work very differently. This is particularly important in the context of uk share save saye calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk share save saye computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Can I sell my shares immediately after exercising?
Yes. Once you exercise the SAYE option, you own the shares outright and can sell them immediately if you wish. Any gain between the market value at exercise and the sale price is subject to Capital Gains Tax in the normal way. This is particularly important in the context of uk share save saye calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk share save saye computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Pro Tip
Even if you are uncertain about the company's share price prospects, a SAYE scheme is a win-win: if the price rises, you exercise and profit; if it falls, you get your savings back. Always participate at the maximum affordable level, as the downside is simply receiving your savings back.
