What Are SEIS and EIS? Quick Definitions

Before diving into taxes, let’s clarify SEIS and EIS at a glance.

SEIS (Seed Enterprise Investment Scheme)

  • Designed for very early-stage startups.
  • Investors can claim up to 50% income tax relief on investments up to £100,000 per tax year.
  • Offers capital gains tax relief if shares are held at least three years.

EIS (Enterprise Investment Scheme)

  • Targets slightly larger or more established companies.
  • Income tax relief of 30% on investments up to £1 million (or £2 million if certain conditions apply).
  • Defers capital gains on other assets or claims CGT exemption on EIS shares after three years.

Both schemes aim to encourage investment in UK startups by providing generous tax breaks. They’re powerful—but only if you follow HMRC rules precisely.

Tax Implications of SEIS/EIS Crowdfunding

Understanding the way SEIS/EIS crowdfunding interacts with UK tax will save you time and money.

Income Tax Relief

Investors can deduct a percentage of their investment from their income tax bill:
– SEIS: 50% relief on up to £100,000.
– EIS: 30% relief on up to £1 million.
To qualify, the company must meet SEIS/EIS criteria and hold investor funds for a minimum period (usually three years).

Capital Gains Tax (CGT) Exemption

If you sell SEIS shares after three years:
– Profits are exempt from CGT.
– Losses can be offset against income tax (limited to relief on acquisition).

EIS shares also qualify for CGT exemption after qualifying period and conditions.

Loss Relief

Should a company fail, you can offset your loss against your income tax bill (limited by your effective tax rate). This boosts the overall SEIS tax exemption and acts as a safety net.

Inheritance Tax Relief

SEIS and EIS shares held for at least two years are typically exempt from Inheritance Tax, assuming they remain unquoted. This feature makes them an attractive long-term holdings.

Reporting and Compliance: Stay on HMRC’s Good Side

Small mistakes can lead to penalties. Here’s what both startups and investors must do:

For Startups

  • Apply to HMRC for advance assurance before launching.
  • Issue compliance certificates (Form SEIS3/EIS3) to investors.
  • Submit accurate annual returns and company accounts.
  • Keep detailed records of funding rounds and share allocations.

For Investors

  • Receive and keep your SEIS3/EIS3 certificates.
  • Claim income tax relief via your self-assessment tax return.
  • Report share disposals correctly to benefit from CGT relief.
  • Retain proof of holding periods to secure inheritance tax relief.

Proper record-keeping underpins every SEIS tax exemption claim. Use cloud accounting or specialist advisers to avoid slip-ups.

Practical Steps for Startups and Investors

Rolling out a successful, tax-efficient crowdfunding campaign is a team effort. Here’s a straightforward roadmap:

  1. Plan Early
