SEIS/EIS Audio Guide for Founders: Current Reading Companion
An introductory SEIS/EIS audio resource with a current written reading guide for eligibility, applications, company forms and investor tax claims.
This earlier audio series introduces questions founders may need to consider before raising investment through SEIS or EIS. It discusses the funding journey, preparing for advance assurance and matters to consider after an assurance letter.
Recording status: the series has not been re-recorded or technically reverified as part of the September 2026 written-content update. Its original recording dates are not established on this page. Treat it as background discussion and check current written guidance before relying on a threshold, form or process.
Listen to the introductory session
The original audio series listing provides access information. Check the available content and terms there. This page does not promise that the recording alone is sufficient for a current application.
Current written guidance
SEIS involves separate checks for the company, the shares and each investor. Advance assurance concerns the disclosed proposal; it does not confirm every investor's entitlement. After issue, the company must complete the compliance process before issuing investor certificates.
Use the written guides below for current thresholds, conditions, forms and worked examples. They also explain the distinction between an investor's tax relief and the company's funding.
- SEIS explained: company and investor eligibility
- Advance assurance: application, documents and HMRC timings
- After investment: SEIS1, SEIS2 and SEIS3 certificates
- Claiming income tax relief and carry-back
- SEIS loss relief with worked examples
- Capital gains: reinvestment relief and disposal exemption
