Employee Share Scheme Guide for UK Employers (2025 Edition)
Written for founders, HR leads and finance teams navigating the post-2024 rules.
1 Why offer a share scheme at all?
Equity turns staff into co-owners. UK research shows companies with broad-based ownership post 6–8 % higher productivity and 30 % lower staff churn than comparators. More practically, share awards can offset cash-tight salary budgets and are usually deductible for corporation tax.gov.uk
2 Which schemes are on the table?
| Scheme | Typical user | 2025 limits & tax break (headline) |
|---|---|---|
| EMI (Enterprise Management Incentive) | Tech/SaaS scale-ups < £30 m gross assets & < 250 FTE | Grant up to £250k options per employee; no Income Tax/NIC if option price ≥ market value; notification now by 6 July after year-end for options granted ≥ 6 Apr 2024.gov.ukosborneclarke.com |
| CSOP (Company Share Option Plan) | Later-stage or larger private/public companies | Grant value doubled to £60k from 6 Apr 2023 and ‘worth-having’ share-class rule scrapped. No tax on grant/exercise if price ≥ market value.vestd.com |
| SAYE (“Sharesave”) | All-employee retail & PLC schemes | Staff save up to £500 / month; 3- or 5-year options at up to 20 % discount. Latest Bank-rate-linked bonus from 21 Feb 2025: 0.8 (3 yr) / 2.3 (5 yr). Interest & discount tax-free.gov.uk |
| SIP (Share Incentive Plan) | Broad workforces where equal allocation matters | Free shares up to £3,600/yr, partnership shares up to £1,800/yr (or 10 % salary) plus up to 2 matching shares per partnership share. Tax-free after 5 yrs.gov.ukglobalshares.com |
| Growth shares(unapproved) | Mature PE-backed or IPO-track firms | Employees buy a new share class with a “hurdle value” so only future growth is taxed—capital gains on sale; no statutory limits.bdo.co.uk |
| Phantom/virtual shares | Companies wary of diluting cap table | Cash bonus mirrors share price at exit; fully flexible but taxed as cash bonus when paid.sprintlaw.co.uk |
3 Regulatory & tax updates you must know (2023 – 2025)

-
CSOP expansion – £60k limit and relaxed share-class rules now live.gov.uk
-
Dividend & CGT squeeze – annual dividend allowance cut to £500 and CGT annual exempt amount to £3,000from April 2024, making tax-advantaged plans even more valuable.kpmg.com

4 Choosing the right scheme
Ask four quick questions:
| Decision-point | Steer |
|---|---|
| Company size & assets | EMI tops the tax table but shuts out groups > £30 m gross assets. Otherwise look at CSOP. |
| All-staff vs select group? | SIP & SAYE must invite all qualifying employees on similar terms; EMI/CSOP can be selective. |
| Cashflow impact | SAYE brings cash in via staff savings; EMI/CSOP/Growth shares are cash-neutral until exercise/sale; Phantom shares create a future cash outflow. |
| Exit horizon | If an IPO/PE exit is within 3–5 years, options (EMI/CSOP) usually beat SIP due to faster vest; phantom works where buy-back is likely. |
5 Implementation roadmap (90 days)
| Day | Action |
|---|---|
| 0 – 15 | Scope & model: confirm scheme purpose, eligible group, shares available and valuation approach. |
| 16 – 30 | Adviser engagement: instruct tax counsel and independent valuer; draft plan rules & option agreements. |
| 31 – 60 | Board & shareholder approvals; file any advance HMRC valuation (optional for EMI/CSOP). |
| 61 – 75 | System prep: register scheme on HMRC ERS portal, set up cap-table software (e.g., Ledgy, Carta). |
| 76 – 90 | Launch & educate: issue first grants, run staff webinars on tax & liquidity, calendar 6 July filing reminders. |
6 Common pain-points (and fixes)
| Pitfall | How to avoid |
|---|---|
| Granting EMI to contractors | EMI requires employees working ≥ 25 hrs/week or 75 % of time. Use growth shares or unapproved options instead.pinsentmasons.com |
| Missing HMRC deadlines | Automate reminders: EMI/CSOP/SIP/SAYE returns are all due 6 July; late filing wipes tax relief.pinsentmasons.com |
| Using out-of-date share valuations | HMRC accepts valuations for 90 days (EMI) or 30 days (CSOP) – refresh if grants slip. |
| Forgetting leavers | Build “good/bad leaver” rules into option deeds and trust deeds up-front to avoid disputes. |
7 Best-practice tips for 2025
-
Model secondary liquidity early – staff ask “when can I sell?”; partner with seed investors or EOT to buy back options.
-
Layer schemes – combine EMI for key talent with SAYE or SIP for wider staff to maximise engagement.
-
Track environmental, social & governance (ESG) KPIs – bonus share “multipliers” tied to ESG goals are HMRC-friendly if fixed objectively at grant.
-
Communicate in plain English – short FAQ videos beat 40-page scheme booklets and reduce support tickets.
8 Take-away
A well-chosen employee share scheme is now mission-critical: rising income-tax pressure and tighter dividend/CGT bands mean equity is the most efficient reward tool left in a UK employer’s kit. Pick the structure that fits your size, cashflow and exit timeline, meet the 6 July compliance drum-beat, and you’ll convert colleagues into long-term value-creators rather than short-term salary-seekers.
