Advance assurance is written confirmation from HMRC that your company is likely to qualify for SEIS or EIS tax reliefs. It gives investors confidence that their investment will be eligible for these benefits.
A Founder’s Guide: Advance Assurance Under the Venture Capital Scheme
It’s not a legal requirement, but most investors won’t commit without it. Advance assurance reassures them that your business meets HMRC’s criteria and increases your chances of raising funds.
HMRC typically takes six to eight weeks to process an EIS advance assurance application. Timelines vary depending on the completeness of your documents and HMRC’s workload.
There’s no strict expiry date. Your assurance stays valid as long as your company details remain consistent with the application. If circumstances change, you should seek updated advice.
You’ll need to submit an application to HMRC with your business plan, financial forecasts, use of funds, and supporting documents. You can apply directly or work with Sleek, who will prepare and manage the submission for you.
Typically you’ll need a business plan, financial projections, company structure, shareholder details and a cover letter explaining the raise. HMRC may also request Articles of Association and proof of trading activity.
Yes. Sleek’s SEIS and EIS experts manage the full process from preparing documents to liaising with HMRC, ensuring your application meets the requirements and has the best chance of approval.
