Frequently asked questions
Still have questions about SEIS/EIS Advance Assurance?
-
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 SEIS/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. -

Our combined expert support and automated workflow help to streamline the process. Our SEIS/EIS experts are with you every step of the way and can guide you through the process from start to finish – unlimited support is included at no extra cost.
At the end of the process once your documents are finalised, we will also submit on your behalf on HMRC’s website. It’s free to sign up and get started. -
How long does Advance Assurance take?
The Advance Assurance process should all be complete within 3 weeks but is often much quicker. It takes roughly 30 minutes to complete the application on our platform, a day or two while we review it before we submit it, and then the rest of the time is with HMRC (they take about 15 days). -
What documents do I need for the application?
As a minimum you'll need to send HMRC your: Business Plan / Pitch Deck, 3 year projected Financials, Share Register and the Application form. 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 / Term Sheet. -
What are the excluded activities?
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.
