    Frequently asked questions about SEIS/EIS compliance

    • What are SEIS and EIS?

      The Enterprise Investment Scheme (EIS) and the Seed Enterprise Investment Scheme (SEIS) are UK government initiatives which grant private investors a significant tax break when investing in early-stage, ‘high-risk’ companies.

      Most investors in the UK will only invest in these types of companies if they are SEIS/EIS compliant, so it should be a priority for founders seeking investment.
      You can learn more in our SEIS and EIS essential read for UK startups and Our complete guide to SEIS.
    • What's the difference between SEIS and EIS?

      Both the SEIS and EIS encourage investment in UK businesses. The difference between the schemes is the type of company they cover, and how much tax relief investors get.

      The Seed Enterprise Investment Scheme is for investments in early-stage companies.

      The Enterprise Investment Scheme is for investments in medium-sized startups.

      With both schemes, investors can invest in qualifying companies in return for Income Tax relief. For SEIS, they can invest up to £200,000 per tax year for 50% tax relief. (Before 6 April 2023, this limit was £100,000 per tax year.)
      For EIS, it’s up to £1 million per tax year for 30% tax relief.

      For both SEIS and EIS, investors pay no Capital Gains Tax on any profit they make from selling their shares, as long as they’ve held the shares for at least three years.

      Learn more in our Our complete guide to SEIS.
    • How are SEIS/EIS compliance and advance assurance different?

      SEIS/EIS Advance Assurance is confirmation from HMRC for investors that a company is eligible for SEIS or EIS funding. Before offering SEIS or EIS investment opportunities, companies can apply to HMRC for SEIS/EIS Advance Assurance with SeedLegals.

      SEIS/EIS Compliance is the official certification from HMRC that investments in your company qualify for the scheme (i.e. your company is SEIS/EIS compliant).

      For your company to remain SEIS/EIS compliant, you must stay eligible and follow the scheme rules for at least three years after the investment(s), otherwise, HMRC can withhold or withdraw the tax reliefs from your investors.

      You can read more about how SEIS and EIS work on the HMRC website.
    • Should I ask for Advanced Assurance for companies I invest in?

      Advanced Assurance is not a necessary requirement, however, most investors require the company they are are investing in to have Advance Assurance from HMRC before they invest to ensure they are eligible.
    • Do I need an SEIS/EIS compliance certificate?

      It depends. To get SEIS/EIS tax relief, the investor must meet certain criteria, so with a nominee structure it’s possible not all of your investors will qualify.

      For more about the SEIS/EIS eligibility criteria for investors, read our article: SEIS and EIS rules for startup investors.
    • When can I claim my SEIS/EIS relief?

      Investors can claim their SEIS/EIS tax relief for the tax year their shares were issued. It is best practice for companies to complete their SEIS/EIS compliance promptly - so you can get your certificates to complete your tax returns and get the tax relief.
    • We led a nominee structure for our investment so have multiple investors - do I have to do more than one SEIS/EIS compliance application with SeedLegals?

      No. Whether you have one investor or one thousand investors, our SEIS/EIS compliance service covers as many investors as you need.
