expert team

The Seed Enterprise Investment Scheme (SEIS) is a UK government program designed to promote investment in small and early-stage companies. It offers attractive tax incentives to individual investors who support these startups. SEIS encourages investors to take calculated risks by providing them with substantial tax reliefs.

Key Features of SEIS

SEIS offers the following benefits to investors:

  1. Income Tax Relief: Investors can claim up to 50% of their investment amount as income tax relief, helping reduce the overall tax liability.

  2. Capital Gains Tax Exemption: Any gains made from the sale of SEIS shares are exempt from Capital Gains Tax (CGT) if certain conditions are met.

  3. Loss Relief: In case of business failure, investors can offset their losses against other taxable income, further reducing the risk.

  4. Carry-Back: Investors can carry back the SEIS investment to the previous tax year, maximizing the tax relief.

  5. Investments: These can be made from £1000 to £200,000 within any one tax year.
