What Are EIS & SEIS?
The Enterprise Investment Scheme (EIS) and Seed Enterprise Investment Scheme (SEIS) are HMRC-approved tax relief schemes that help startups raise funds. Investors receive income tax relief, capital gains exemptions, and loss relief β making your business a more attractive opportunity.
Weβll guide you through the requirements, help you qualify, and manage the entire process from advance assurance to post-investment compliance.
Advance Assurance You Can Rely On
Advance assurance gives investors peace of mind. But the application must be detailed, accurate, and compliant with HMRC criteria. We prepare and submit a full pack β including your business plan, financial forecasts, cap table, and investor details β ensuring your startup is approved efficiently.
