£250,000 at 50% relief — but only within three years of the day you started trading. Hassle checks whether you still qualify against your real data, and labels every figure that's only a guess.
Not tax advice. We show what we can verify and flag what we can't.
SEIS runs from the day you started trading, not the day you incorporated. Most founders find out how much of it they've spent when they're already raising.
Both schemes need advance assurance before most angels will commit, and assurance needs a three-year forecast showing why you need the money and how it gets spent. Figures shown are the current HMRC limits; they change, and your circumstances decide which apply.
Every SEIS template on the internet produces a document where your guess and your bank statement look identical. That's the document HMRC reads.
An experienced angel doesn't evaluate an SEIS cheque at face value — they net off the relief and the loss relief first. This is that calculation, so you know what they know before you're in the room.
For a 45% taxpayer who qualifies for full relief, a £10,000 SEIS position carries roughly £2,750 of genuine downside — about 28p in the pound. That is roughly the figure an experienced angel is working from — before SEIS capital-gains reinvestment relief, which can reduce it further. Whether or not it is ever said out loud.
Downside framing beats upside pitching with anyone who has lost money before — which is every angel worth having on your cap table.
Promising relief you can't deliver. If your company fails a gate, they lose the relief and you lose the relationship. That's why the gates come first on this page and not last.
SEIS and EIS relief attaches to newly issued shares. A SAFE isn't shares, and the way most are drafted, the money sits outside the scheme. A UK Advance Subscription Agreement can be structured to keep it.
Hassle presents both instruments in plain English, shows what each does to relief, and defaults UK rounds to an ASA. Your solicitor still drafts and signs off the documents — we don't.
SEIS is not a solo exercise. Your accountant confirms gross assets and your solicitor drafts the ASA. Both can work inside the same room — on scopes you set, that you can revoke.
Gross assets, employee count and qualifying trade are your figures, not ours. Invite your accountant to confirm them against the books — the pack updates and the gate stops saying “your assumption”.
A legal reviewer gets the corporate and legal register only. No technical evidence, no customer data — the scope is enforced, not promised.
Every adviser grant is one you approve, capped to its own scope, and revocable in seconds. It appears in your audit log exactly like an investor request — nobody is added on your behalf.
Every adviser grant is scoped, time-boxed and revocable, and shows up in the same audit trail as an investor request. Founder approval is required for all of them — nobody is added on your behalf.
Everything runs against evidence you've already connected. Nothing is invented to fill a cell.
No point modelling three years of P&L for a company that fails on gross assets. The checks run first.
HMRC needs to see why the raise is necessary and where it goes — so we build to the funding gap, not to a vanity number.
Each figure in the pack says where it came from. See the evidence model
Most SEIS tools stop the day the money lands. That is the day your obligations start. The shares have to be held, the money has to be spent on the qualifying trade, and a disqualifying event in the next three years can claw the relief back — from your investors, not from you.
Hassle keeps watching. The same connected sources that proved your gates keep proving them, and you get told when something moves.
Hassle is not a tax adviser. Compliance tracking surfaces what we can observe from connected evidence; it does not replace your accountant or an HMRC determination.
HMRC wants a three-year forecast with your advance-assurance application. Building it from scratch in a spreadsheet is the part founders stall on — so Hassle populates it from the accounts you already connected, labels every figure as actual or assumption, and hands you the file. Hassle isn’t a law firm and doesn’t file your assurance; you approve exactly what leaves.
Month 1 to month 36 — revenue, cost of sales, gross margin, overheads and EBITDA. Connected months come from your actuals; the rest are your assumptions, marked as assumptions.
The forecast plus the eligibility gates, use of funds and cap table context — every figure stamped verified or assumed, so a reader can see which is which.
Export it and take it to your accountant, your solicitor, or whichever platform is running your round. The pack is written to be read by all three.
Hassle is not a tax adviser, accountant or law firm, and nothing here is advice on your specific circumstances. SEIS and EIS eligibility is determined by HMRC.
Rates and limits shown are as at 29 July 2026, checked against HMRC — apply to use SEIS and HMRC — apply for advance assurance. Thresholds change at fiscal events; if the date above is more than six months old, treat every figure on this page as unverified and check the HMRC guidance directly.
