SEIS / EIS advance assurance and compliance & certificates

FounderCatalyst simplifies the process of obtaining SEIS/EIS advance assurance, compliance and certificates - ensuring your investors benefit from tax relief while you stay focused on growing your business.

Why SEIS/EIS matters

SEIS/EIS tax relief is one of the strongest incentives for early-stage investors. Securing these benefits can significantly increase investor confidence and help you close your round faster.

FounderCatalyst ensures the process is handled quickly, accurately and without unnecessary complexity.

SEIS + EIS

Inheritance Tax (IHT) relief

Shares in SEIS/EIS-qualifying companies are typically exempt from IHT via Business Property Relief once held for at least two years. With IHT at 40%, this can meaningfully reduce estate tax exposure on death.

SEIS only

CGT reinvestment relief

SEIS lets investors exempt 50% of a capital gain from CGT when that gain is reinvested into qualifying SEIS shares - a powerful way to recycle gains from other assets.

EIS only

CGT deferral relief

EIS allows investors to defer CGT on gains from other assets when those gains are reinvested into EIS shares - pushing the tax bill down the road.

Real results from real founders

Don't just take our word for it - here's what founders have achieved with FounderCatalyst.

“Phenomenal! Sam and his team at FounderCatalyst helped demystify our route ahead and provided invaluable insight and support in obtaining our SEIS Advanced Assurance. I don't believe we would have done it without him. What's more, the approval only took 5.5 business hours from submission. Far faster than HMRC was advising themselves. I firmly believe this was down to the solid preparation and support provided by FounderCatalyst.”

“We were referred to FounderCatalyst and told that they were good, but our advance assurance submission received a positive response from HMRC in 25 hours – that is better than good!”

“Sam and team provide a faultless service. I've been incredibly impressed with the rapid response time of any questions I send, and the level of detail and reassurance provided to make sure we fully understand the process. We flew through the HMRC (S)EIS Advance Assurance process: submitting it just before 5pm on a Monday, and having received confirmation of it by 1:30pm the next day! Can't get much better than that. Really very happy to have chosen FounderCatalyst.”

“We were unsure how to approach SEIS/EIS advance assurance, but FounderCatalyst made the process a breeze. Even better, we had a positive advance assurance confirmed by HMRC in less than five and a half hours! Crazy good. Sam and his team are incredibly knowledgable, clear, helpful and thorough. We could not recommend them more!”

“I’d heard that FounderCatalyst’s SEIS advance assurance was lightning quick from another founder, but they’ve excelled themselves with Archive This Ltd. Full advance assurance received from HMRC in less than 3 working hours.”

“We started our new company under our old company. Rookie mistake. This meant we fell outside of the timeline for EIS by more than a few years. FounderCatalyst worked with us on an appeal. Our new company was different to our old one. We had invested into it's development and were turning revenue. We got the thumbs up from HMRC. Was a happy day.”
