Seed Enterprise Investment Scheme (SEIS)

“A UK scheme giving individual investors income tax relief and other tax breaks for buying new shares in very young companies that meet HMRC's rules. The Seed Enterprise Investment Scheme (SEIS) covers smaller, earlier rounds than the Enterprise Investment Scheme (EIS).”

Why Seed Enterprise Investment Scheme (SEIS) matters to a first-time founder

For many UK angels, the tax relief is a big part of why they invest at the earliest stage. If your company or the share issue does not qualify, some investors will walk away or cut their cheque, and mistakes discovered after the money is spent cannot always be fixed. Knowing the rules early shapes how you structure the round, which agreement you use and how you spend the money.

Examples of Seed Enterprise Investment Scheme (SEIS)

An angel is willing to invest £20,000 if the shares can sit inside SEIS. You apply for advance assurance, use an agreement that fits the scheme, and spend the money on the growth of the company rather than on buying out an old shareholder. If the rules are missed, the investor’s reason for the cheque can disappear after the money is spent.

Common misunderstanding

People think any small UK company, and any early instrument, qualifies. Selling existing shares, using the wrong agreement, or being too far along can all sit outside the scheme. EIS is a related scheme with different company, investment, and share-issue rules. A company may use EIS after SEIS, but one does not automatically lead to the other. This page is not tax advice.

When to use it

Look at it before the first UK angel round, not after you have already issued the shares in a shape that cannot qualify. Check the applicable scheme before shares are issued, and get that answer before you promise the relief.
