Tout savoir sur EIS Tax Relief Calculator
📋Présentation+
Computes EIS reliefs (2025/26): 30% income tax relief on up to £1,000,000 invested per year (£2,000,000 when the excess goes into knowledge-intensive companies), capped at your income tax liability; deferral of capital gains reinvested; and the loss-relief cushion that limits the worst-case downside.
💡 Bonnes pratiques
- Relief cannot exceed your income tax liability for the year (a carry-back to the previous year is possible).
- If the company fails, loss relief on the net investment at your marginal rate cushions the downside — worst case ≈ 38.5% of the investment for a 45% taxpayer.
- Hold at least 3 years or the income tax relief is clawed back.
🔢 Exemple concret
£10,000 EIS investment while deferring a £50,000 gain: £3,000 income tax relief (net cost £7,000), £12,000 of CGT deferred, and a worst-case loss of £3,850 after loss relief at 45%.

- Income tax relief (30%)
- A tax reducer worth 30% of the investment, up to £1m/year (£2m with KIC) — withdrawn if the shares are sold within 3 years.
- CGT deferral
- Gains from any asset reinvested in EIS are deferred — the gain revives when the EIS shares are disposed of. Growth on the EIS shares themselves is CGT-free after 3 years.

FAQ — EIS Tax Relief Calculator
How much EIS income tax relief can I claim?+
30% of the amount invested, on up to £1,000,000 a year — or £2,000,000 when everything above £1m is invested in knowledge-intensive companies. The relief cannot exceed your income tax bill.
How does EIS CGT deferral work?+
A chargeable gain from any asset reinvested in EIS shares is deferred: no CGT now, but the gain revives when you dispose of the EIS shares. The EIS shares' own growth is exempt after 3 years.
What happens if the company fails?+
You can set the loss (net of the 30% relief) against income at your marginal rate — for a 45% taxpayer the total downside on a failed EIS investment is roughly 38.5p per £1 invested.
