The Enterprise Investment Scheme (EIS) and Seed Enterprise Investment Scheme (SEIS) are central tools for UK tax-efficient investment into early-stage and high-growth companies.

For Professional Services firms, including accountancy practices, law firms, tax advisers, corporate finance boutiques and wealth managers, these schemes represent both a significant advisory opportunity and an area requiring specialist technical expertise. The EIS Association offers a Corporate Membership for Professional Services firms, providing access to technical guidance, policy insight, networking and best-practice resources to support firms advising in this space.

Professional advisers play a crucial role in helping clients understand the opportunities, risks, structuring considerations and compliance requirements associated with these schemes. Both EIS and SEIS offer investors income tax relief, capital gains tax exemptions, and loss relief, making them highly attractive for clients seeking exposure to innovative UK businesses within a tax-efficient framework.

SEIS is designed for very early-stage companies raising their first external capital, with investment limits of up to £200,000 per tax year. EIS targets businesses that are scaling, with annual investment limits of £1 million, or £2 million for companies meeting Knowledge-Intensive (KI) criteria.

Professional Services firms must carefully assess eligibility, including trade activities, company age, employee numbers, independence tests and financial thresholds, to ensure clients benefit from the full range of available tax reliefs while maintaining compliance with HMRC requirements.

Advisers can add significant value by guiding clients through scheme suitability assessments, portfolio diversification, structuring considerations and risk mitigation strategies. By combining technical expertise with practical commercial insight, firms ensure investors make informed decisions while supporting UK businesses in accessing crucial growth capital.

EIS and SEIS investments are long-term and illiquid, with higher-than-average risk. Professional advisers should ensure clients understand these risks, including the potential impact of company failure, the conditions for retaining relief, and the mechanisms for claiming income tax relief, CGT deferral and loss relief.

Ensuring HMRC compliance is essential, including reviewing Advance Assurance status, company documentation, and verifying EIS3 or SEIS3 certificates before clients submit claims.
