SEIS is a government-approved investment scheme that encourages funding in early-stage companies. The scheme is designed to support start-ups during their crucial stage when looking for investment by reducing their investors’ capital risk in the form of generous tax relief.
However, before your investors commit, most of them will want to know if your business is eligible for SEIS. To provide them with the security they need, you can apply for SEIS Advance Assurance clearance which will prove your eligibility and increase your chances to secure investment.
The SEIS scheme is proven to be very popular: your investors will have the potential investment risk reduced, your company will enhance opportunities to receive funding and the UK economy will see an increase of investment in its most innovative businesses.
What are the benefits of SEIS
If your business is eligible for the SEIS scheme, you and your investors will benefit in several ways.
Your company will be able to raise up to £250,000 (for shares issued on or after 6 April 2023) under the SEIS scheme within the first 3 years of trading.
Your investor(s) will receive income tax relief of up to 50% of the value of the money invested which means 50% of the risk of the investment. An individual investor can invest as much as £200,000 in any tax year to be eligible for this tax relief.
If your company succeeds and the investors make a gain on the sale of their shares, the gain is exempt from Capital Gains Tax (CGT). In case your company fails, your investors can offset the loss on the shares against their income tax bill.
Relief can be carried back to the previous year to reduce that year’s tax liability depending on the annual limit for the previous year.
Who is eligible for SEIS
In order to receive SEIS Advance Assurance clearance, your company will need to meet several requirements, including:
- To have a permanent establishment in the UK;
- To have less than £350k of gross assets before any shares are issued;
- To have less than 25 full-time equivalent employees at the time the shares are issued.
If you have previously received investment through the EIS or from a Venture Capital Trust, then your business is not eligible for this scheme.
