SEIS and EIS Advance Assurance is a provisional confirmation from HMRC that the investment made into the company will be eligible for tax relief. There is no mandatory obligation from the company to apply to advance assurance, however it is a very useful tool as it gives preliminary assurance to the investors that they will receive relief by investing into the company. Advance Assurance applies to both SEIS and EIS.

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.

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.
