SAYE & SIP: The UK Employer's Complete Guide
This guide is built for UK employers weighing up SAYE, SIP, or both: it covers the tax mechanics, the HMRC self-certification requirements, the setup steps companies most often get wrong, and a decision framework for choosing the right scheme for your workforce and listing status.
LTIP Guide: RSUs, Stock Options & Performance Shares
HMRC statistics, tax benefit tables, setup checklists, and a decision framework – everything you need to evaluate and run the UK’s two most powerful all-employee share schemes.
The UK government offers four tax-advantaged employee share schemes. Two of them – SAYE and SIP – are designed for every eligible employee, not just senior leaders.
That’s what makes them different. And that’s what makes them powerful.
SAYE (Save As You Earn), also known as Sharesave, lets employees save a fixed amount each month directly from their pay over three or five years. At the end of the savings period, they can use those savings to buy company shares at a price locked in at the start — often at up to a 20% discount. If not, they simply take their savings back in full. There is no downside for the employee.
SIP (Share Incentive Plan) puts shares directly into employees’ hands through up to four mechanisms: free shares gifted by the employer, shares purchased from pre-tax salary, employer-matched shares, and dividend shares reinvested back into the plan. Shares held for five years are completely free of Income Tax and National Insurance.
Sneak Peak of what's inside the guide
- The tax benefit most employers miss: basic-rate taxpayers save 32% on every pound invested before the share price moves.
- The numbers behind the business case – 81% of companies running SAYE or SIP told HMRC it improved their business outcomes. These are government figures, not vendor claims.
- The setup steps most companies get wrong – self-certification doesn’t mean low-stakes. The guide covers exactly where companies fall short on HMRC registration and annual returns.
- SAYE or SIP – which is right for you? – the answer depends on your listing status, workforce, and objectives. The guide includes a decision framework to make it clear.

Frequently asked questions about equity plan administration
What is equity plan administration?
Equity plan administration is the end-to-end process of managing employee share-plans – covering award issuance, vesting tracking, settlement processing, regulatory compliance, and participant communication. Effective administration ensures share plans operate accurately, on time and in accordance with accounting standard such as IFRS 2 (Share-based Payment) and ASC 718, while providing a transparent experience for participants.
What does ShareForce include beyond the software platform?
Every ShareForce client receives a dedicated implementation manager who leads onboarding and then becomes their long-term client manager. Depending on your needs, the engagement includes scheduled check-ins, quarterly reviews, proactive vesting support, and direct access to in-house compliance expertise across IFRS 2, ASC 718, and local jurisdiction tax requirements. Participants have access to a dedicated helpdesk for queries about holdings, vesting dates, and settlements.
How long does ShareForce implementation take?
A typical ShareForce implementation takes six to eight weeks. The process covers data migration, platform configuration to your plan structures and vesting schedules, and hands-on training for Finance and HR administrators. Data migration is handled entirely by the ShareForce team, eliminating the manual effort and risk of a self-serve setup.
What compliance frameworks does ShareForce support?
ShareForce supports equity plan administration under IFRS 2 (Share-based Payment), ASC 718 (Compensation — Stock Compensation), and local jurisdiction tax requirements across multiple countries. The platform is used by companies with single-country plans through to complex multi-jurisdiction programmes spanning different regulatory regimes.
What are the key challenges in equity plan administration?
The most common challenges in equity plan administration include missed vesting deadlines, settlement calculation errors, difficulty evidencing compliance for audit, and the administrative burden of managing participant data across jurisdictions. Manual spreadsheet-based approaches increase error risk and make audit preparation time-consuming. Purpose-built equity plan administration software addresses these challenges by centralising the full award lifecycle in a single, auditable system.
