Share Incentive Plan Overview
What is a Share Incentive Plan?
A Share Incentive Plan (SIP) is a government-approved employee share scheme that allows workers to buy shares in their employer’s company with significant tax advantages. Employees can contribute up to £1,800 per year from their gross salary before tax and National Insurance deductions.
Types of SIP Shares
- Partnership Shares: Shares you buy with deductions from your gross salary
- Free Shares: Shares given to you by your employer (up to £3,600 per year)
- Matching Shares: Additional shares given by your employer when you buy partnership shares
- Dividend Shares: Shares purchased with dividends from other SIP shares
Tax Benefits
- No Income Tax on partnership shares when purchased
- No National Insurance contributions on partnership shares
- No Capital Gains Tax if held for 5+ years
- Dividend reinvestment without immediate tax liability
Holding Period Requirements
To maximize tax benefits, shares must be held in the SIP for specific periods:
- Less than 3 years: Income tax and NI charged on withdrawal
- 3-5 years: No income tax or NI, but may face Capital Gains Tax
- 5+ years: No tax charges on withdrawal
Annual Limits 2024-2025
- Partnership shares: £1,800 per year
- Free shares: £3,600 per year
- Matching shares: No specific limit (usually 2:1 ratio)
- Dividend shares: £1,500 per year
Key Considerations
- Share prices can go down as well as up
- Your investment and employer are linked
