The Enterprise Investment Scheme (EIS) and Seed Enterprise Investment Scheme (SEIS) are UK government tax reliefs designed to encourage individuals to invest in early-stage, unquoted companies by offering significant income tax and capital gains tax reductions.
For agency founders, EIS and SEIS are powerful tools for raising external investment while offering investors a highly tax-efficient proposition. Under SEIS, which targets very early-stage startups, an investor can receive 50% income tax relief on investments of up to £100,000 per tax year (2025/26). For example, if an investor puts £20,000 into your SEIS-eligible agency, they reduce their income tax bill by £10,000. Additionally, any gain on the sale of SEIS shares after three years is exempt from capital gains tax, and investors can defer other capital gains by reinvesting them into SEIS shares.
EIS applies to slightly more established companies and offers 30% income tax relief on investments of up to £1,000,000 per tax year (or £2,000,000 for knowledge-intensive companies). Like SEIS, EIS shares held for at least three years are free from capital gains tax on disposal. Both schemes also provide loss relief: if the company fails, investors can claim relief against income or capital gains at their marginal rate, reducing their effective risk.
To qualify, your agency must meet several conditions. It must be a UK-based, unquoted trading company (not, for example, a property or financial services business). It cannot have more than £15 million in gross assets for EIS or £200,000 for SEIS. The shares must be newly issued, not listed on a recognised stock exchange, and the company must use the funds for a qualifying trade within two years. Importantly, you cannot be a "connected person" (e.g., a director or employee) to claim the income tax relief, though you can invest as a non-connected individual.
For agency founders, the key advantage is that EIS and SEIS make your agency far more attractive to angel investors and venture capital trusts. They effectively reduce the investor's risk while giving you access to growth capital without immediate dilution of control, as the reliefs are tied to the investor, not the company.
When this matters for agency founders: EIS and SEIS matter most when you are raising external equity funding for the first time, typically in the seed or early growth stage. They are essential if you want to attract sophisticated investors who demand tax-efficient structures, and they can significantly lower the cost of capital for your agency's expansion.
