Can my company lose SEIS/EIS status after the investment?
By SuLe · Updated 8 July 2026
Yes. SEIS and EIS status is conditional for three years from the share issue: if the company ceases the qualifying trade, excluded activities become substantial, the company is acquired, share capital is repaid or an investor receives value, HMRC can withdraw investors' relief. Most of the accidents are self-inflicted — buybacks, early exits and drifting business models, not HMRC surprises.
Key facts
- The danger zone runs for 3 years from the share issue; investors must also hold their shares for 3 years or income tax relief is withdrawn.
- Status-loss triggers: ceasing the qualifying trade, excluded activities becoming substantial, being acquired, repaying share capital, an investor receiving value.
- HMRC treats excluded activities as "substantial" at around 20% of the trade.
- SEIS money must be spent on the qualifying trade within 3 years; EIS money must be employed within 2 years.
- The CGT exemption on exit needs shares held 3 years and income tax relief given and not withdrawn.
How long do we have to keep the conditions?
Three years from the share issue. Relief is claimed early but earned over time: the company must keep meeting the scheme conditions, and each investor must keep holding their shares, for the full period.
Both sides can break it. An investor who sells at month 20 loses their own relief; a company that trips a trigger at month 20 can take every investor's relief down at once.
There are spending clocks inside the window too — SEIS money must be spent on the qualifying trade within 3 years of the issue, and EIS money must be employed within 2 years.
Which events withdraw SEIS or EIS relief?
HMRC's guidance lists the classic triggers within the three-year period: the company ceasing the qualifying trade, excluded activities becoming a substantial part of the business, the company being acquired, share capital being repaid, and investors receiving value from the company.
| Trigger (within 3 years of issue) | What it looks like in a startup |
|---|---|
| Ceasing the qualifying trade | Shutting the product down, going dormant, or a hard pivot out of trading |
| Excluded activities becoming substantial | A lending or property sideline growing past roughly 20% of the trade |
| The company being acquired | Selling the company at month 30 instead of month 37 |
| Repaying share capital | Buying back a departing co-founder's shares |
| An investor receiving value | Money or benefits flowing back — for example, repaying a loan from an investor |
None of these requires bad faith — they are ordinary corporate events that happen to be toxic inside the window. Check every significant decision against the list first.
Why are buybacks and payments to investors so dangerous?
Because they reverse the bargain the relief was given for: money meant to be at risk in the company quietly comes back out. Repaying share capital — a buyback being the obvious example — is a listed trigger.
"Receiving value" is broader and easier to trip: it catches value flowing from the company to an investor, and its edges are wide. Before any money or benefit moves to an investor inside the window, get the transaction checked.
The classic startup collision is a departing co-founder: the instinct is a company buyback, and inside three years that instinct is expensive. A transfer of shares between individuals avoids the company repaying capital, but structure it with advice.
What if we are acquired within three years?
An acquisition inside the window is a listed trigger — the company being taken over can withdraw the relief investors claimed, and the CGT exemption depends on that relief not having been withdrawn.
This does not mean you can never sell. It means the three-year clock becomes a commercial factor: SEIS/EIS-heavy cap tables often prefer exits timed past the deadline, and investors will expect the conversation.
Some reorganisations and share-for-share structures may be capable of being handled without triggering withdrawal, but this is specialist territory — model it with advisers before signing anything.
Can a pivot cost us our status?
Yes, in two ways. A pivot hard enough to amount to ceasing the qualifying trade is itself a trigger — dormancy and abandoned products are the risk zone, not routine product iteration.
Subtler is the drift trigger: excluded activities becoming substantial. A qualifying software company that starts lending to customers, developing property or living off licensed-in royalties can cross the roughly-20% substantiality line without ever making a formal decision.
Review the trade honestly at each board meeting during the window. The question is not "did we mean to change?" but "what does the company actually do for its money now?"
Worked example
Sofia and Ben's HR-tech company, Loopwork Ltd, raised £180,000 under SEIS fourteen months ago — worth £90,000 of income tax relief across its angels at 50%. Now their third co-founder is leaving, and the plan is for the company to buy back her 12% stake for £30,000.
Their solicitor stops it: a buyback is a repayment of share capital inside the three-year window — a listed trigger that could see HMRC withdraw the angels' relief.
Instead, Sofia personally buys the departing founder's shares for £30,000: a transfer between shareholders, with no money leaving the company. The angels' relief is undisturbed, and the buyback idea is shelved until the SEIS clock has run.

Related questions
Does relief survive if the company simply fails?
Genuine commercial failure is treated differently from voluntary triggers: investors normally keep their income tax relief and can claim loss relief on the remainder, net of relief, against income tax or CGT. A deliberate early wind-up is riskier — take advice first. [More: What happens to SEIS relief if my startup fails?]
Which trades count as excluded activities?
The list includes dealing in land or shares, banking and moneylending, legal and accountancy services, property development, farming, hotels, nursing homes, coal and steel, shipbuilding, energy generation and receiving royalties or licence fees unless from self-created IP. Substantial means around 20% of the trade. [More: Which trades are excluded from SEIS and EIS?]
What happens to SEIS/EIS investors if we exit early?
The company being acquired within three years of the share issue is a status-loss trigger, so an early sale can withdraw the income tax relief your investors claimed — and with it the CGT exemption. Many SEIS/EIS-backed boards time exits with the three-year clock in view. [More: What happens to SEIS/EIS investors in an exit?]
Can we buy back a co-founder's shares without losing SEIS status?
A company buyback inside the three-year window is dangerous: repaying share capital is a listed trigger, and it can pull your investors' relief down with it. Transfers between individuals do not involve the company repaying capital — but structure any departure with advice. [More: Can we buy back shares from a co-founder who has left?]
For three years after the round, ordinary decisions — a buyback, a bridge repayment, an early offer — carry a hidden SEIS/EIS price tag, and it lands on your investors.
