  • Frequently asked questions

    • Do I need Advance Assurance?

      If you're still looking for investors or are in the early stages then Advance Assurance will help you when you are pitching to potential investors. Most S/EIS investors require the company to have Advance Assurance from HMRC before they invest. If your investors are willing to invest regardless of tax relief, then you don't need to worry about applying for Advance Assurance.

    • How long does Advance Assurance take?

      The Advance Assurance process should all be complete within 3 weeks but is often much quicker. Roughly 30 minutes to complete the application on our platfrom, a day or two while we review it and then the rest of the time is with HMRC (they take about 15 days).

    • What do I need to send to HMRC?

      As a minimum you'll need to send your: Business Plan / Pitch Deck, 3 year projected Financials, Share Register, Application form, Cover letter & Checklist. You should also be prepared to send your: Company accounts/Bank statement, details of previous investment & De minimis aid, letter of engagement from your crowdfunding/investment partner, Articles of Association, and Investment Proposal / Termsheet.

    • What are the exluded activites?

      This is a long list but the most common are: legal services, financial services, leasing / renting, energy, property development and agriculture.

    • We incorporated over 2 years ago, can we qualify?

      Yes! For SEIS you just need to prove that you have not been 'trading' for longer than two years and for EIS you have to be within 7 years of your first commercial sale.
