EIS and SEIS Advance Assurance enables companies to receive a provisional indication from HMRC whether they may be eligible to apply for tax relief for their investors. Advance Assurance was introduced by HMRC as full SEIS/EIS eligibility can only be granted by them after the investment has been made.

Advance Assurance was introduced to give investors assurance that their investments should be eligible based on the information they’ve been provided.

At Seedrs, we require any company that wants to offer EIS or SEIS tax relief to provide HMRC Advance Assurance before we complete the investment round. This allows us to offer an extra layer of security and confidence for our investors that an investment will be eligible for tax relief.

To find out more, please visit the official HMRC website.


It’s rare that an EIS or SEIS application is rejected due to unforeseen circumstances. If it is, we will notify investors and reserve the right to cancel the investment due to a change of investment terms. All responsibility for EIS or SEIS eligibility lies with the founders raising funds.

UK taxpayers should note that tax treatment depends on the individual circumstances of each client and may be subject to change in future. To learn more about how SEIS or EIS works, please read the online HMRC guidance or contact your professional tax advisor.
