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.

What's included in our SEIS/EIS service

FounderCatalyst combines automation with expert support to make securing SEIS/EIS simple and fast.

Templates to get you started

Access a professionally designed pitch deck template and financial forecast model to help you prepare materials investors and HMRC expect to see.

Eligibility analysis

We assess your company against HMRC's SEIS/EIS requirements and review your pitch deck, financial model and supporting materials to ensure they include everything HMRC expects.

Advance assurance submission build

We build your SEIS/EIS advance assurance application in the HMRC portal, preparing all the required information and documentation so you can submit with confidence. We also support complex builds including EIS Condition A, B and C, as well as EIS Knowledge Intensive Company (KIC) applications.

HMRC query guidance & responses

While we aim to minimise queries through thorough preparation, HMRC sometimes raise additional questions. When they do, we handle the responses on your behalf - so you don't have to navigate HMRC correspondence yourself.

Post-raise compliance and certificates

After your funding round closes, we support you with SEIS/EIS compliance statements and investor certificates, enabling your investors to claim their tax relief.
