About us

The plain-English guide to SEIS.

SEIS Investments is an independent, education-first publication about the Seed Enterprise Investment Scheme. We are here to make one of the UK’s most useful, and most misunderstood, tax schemes make sense.

Founders and advisers working through SEIS documents

We sit in the middle: independent, clear, and on the reader’s side.

SEIS can change how a company gets started and how an investor backs one, but the information about it is scattered.

The official guidance is accurate and dry, and much of the rest of the web is trying to sell you something. Our job is the readable middle: rigorous on the facts, plain in the telling, and selling nothing.

How we work

What we do

Explain

Plain-English guides for founders, investors and advisers, from first definitions to the fine print.

Analyse

Our own read on the rules, worked examples, and the numbers behind the scheme, refreshed as they change.

Equip

Practical tools, including the SEIS Compass, that turn understanding into a plan you can act on.

How we work

Four standards we hold to on every piece.

Education firstWe explain the scheme. We never give advice or promote an investment.

Plain EnglishJargon is explained on first use, or not used at all.

Primary sourcesEvery figure is checked against gov.uk and HMRC.

Honest about riskWe say plainly that SEIS is high-risk, every time.

The detail is in our Editorial Policy, and the boundary is in our Disclaimer.
