What is EIS/SEIS?

Tax-Efficient Investment Innovation

The UK offers two powerful schemes to encourage investment in innovative businesses: the Enterprise Investment Scheme (EIS) and Seed Enterprise Investment Scheme (SEIS). These initiatives provide significant tax benefits while supporting innovation and growth of startups.

Enterprise Investment Scheme (EIS)

EIS targets slightly more established businesses and provides a range of tax incentives to encourage larger-scale investments.

Key Benefits for Investors

30%

Income Tax Relief

Up to £1-2 million annually

CGT Deferral

Defer CGT on reinvestment

Tax-Free Growth

No UK CGT after 3+ years

Loss Relief

Offset against income or CGT

For Businesses:

Companies can raise up to £12 million in total through EIS funding, with a maximum of £5 million per year.

Seed Enterprise Investment Scheme (SEIS)

SEIS is designed to help very early-stage companies raise capital by offering generous tax reliefs to individual investors who purchase new shares in these businesses.

Key Benefits for Investors

50%

Income Tax Relief

Up to £200,000 annual investment

Tax-Free Growth

No CGT after 3+ years

Loss Relief

Offset against income tax or CGT

CGT Reinvestment

50% CGT reduction on reinvestment

IHT Relief

100% after 2 years ownership

For Startups:

Eligible companies can raise up to £250,000 to support business development, including marketing, staffing, and R&D.

International Investors: No UK Capital Gains Tax

One of the most attractive aspects of EIS and SEIS for non-UK investors is the exemption from UK Capital Gains Tax on qualifying shares.

No UK CGT on EIS/SEIS Gains

Regardless of residency, international investors pay no UK Capital Gains Tax on qualifying shares held for at least three years.

No UK Withholding Tax

Upon sale, gains are returned in full, with no withholding or UK tax deducted at source.

Double Taxation Treaties

Many jurisdictions benefit from bilateral tax treaties which can reduce or eliminate taxation on capital gains.

UK Startup Exposure

Gain exposure to the UK's thriving startup scene in technology, life sciences, fintech, and green innovation.

Why Consider EIS and SEIS?

Whether you're a UK taxpayer or an international investor, EIS and SEIS open the door to early-stage, high-growth opportunities with uniquely generous tax benefits. These schemes are designed not only to support innovation but also to mitigate risk and enhance return potential — a win-win for entrepreneurs and investors alike.

Important Considerations

• Shares must be held for at least 3 years to retain tax relief

• Loss relief is calculated on net loss after income tax relief

• Carry-back allows relief to be applied to prior year's tax bill

• Must be a UK taxpayer to benefit from income tax relief
