SEIS and EIS advance assurance is almost always the gate between a UK university spin-out and its first priced round. A minority university shareholder is usually compatible with both schemes, but the control test, the independence test and the rules on university-linked corporate investors each need checking. This page explains how to get through them.
Investors in UK spin-outs almost always require SEIS or EIS tax relief as a condition of investment. SEIS gives individual investors 50% income tax relief on up to £200,000 a year, plus loss relief and CGT disposal relief. EIS gives 30% relief on up to £1m a year (£2m if the balance is in knowledge-intensive companies). Without advance assurance in hand, most angel syndicates and seed funds will not sign.
Advance assurance is HMRC’s non-binding confirmation that the company and the proposed share issue look like they will qualify. It is not statutory, but it is standard practice. HMRC’s current turnaround is typically four to eight weeks.
| SEIS | EIS | |
|---|---|---|
| Investor income tax relief | 50% | 30% |
| Investor annual limit | £200,000 | £1,000,000 (£2m with KIC balance) |
| Company lifetime raise | £250,000 | £24m (£40m for KIC) |
| Company annual raise | n/a | £10m (£20m for KIC) |
| Company age limit (first qualifying investment) | Within 3 years of first commercial sale | Within 7 years (10 for KIC) |
| Gross assets limit | £350,000 (pre-investment) | £15m pre / £16m post |
| Full-time employees | Fewer than 25 | Fewer than 250 (500 for KIC) |

SEIS and EIS require that no single person controls the issuing company. “Control” has its ITA 2007 meaning: more than 50% of share capital, voting rights or profit-sharing rights, or de-facto power to secure that the company’s affairs are conducted according to that person’s wishes.
Current UK norms sit well inside the test:
A university at 10% or 20% is a long way from control. The quiet failure cases are different:
HMRC’s online advance assurance form is short, but what it asks for in the uploads is substantial. For a university spin-out, we usually submit:
HMRC will not give advance assurance on a hypothetical investor list — it wants real names.
Spin-outs frequently raise on an advance subscription agreement (ASA): investors pay cash now, the company issues shares later when a priced round completes or by a long-stop date. ASAs are compatible with SEIS/EIS if structured correctly:
Get the ASA wrong and HMRC can refuse SEIS/EIS on the shares, even if advance assurance was given on the share issue itself.
A spin-out that qualifies as a KIC gets higher EIS limits (£20m annual, £40m lifetime, up to 10 years old at first qualifying investment, up to 500 employees). The two routes to KIC status:
Plus one of two further tests: at least 20% of employees are “skilled employees” (a Master’s or higher doing R&D), or the company is engaged in work expected to lead to the creation of IP.
Most research spin-outs qualify as KICs. Being able to claim KIC status on the application unlocks higher limits and a longer age window, which matters for a later-stage spin-out that took time to incorporate the IP.
Advance assurance decisions have been running at four to eight weeks in 2026. Common delays:
Our general spoke on how long advance assurance takes covers the current turnaround in more detail.
Usually yes. A minority university stake (5–25%) is well inside the control test. The blockers are preference shares, 51%+ parent structures, and corporate investors on the same round that fail independence tests.
If the TTO holds shares in its own name as a corporate entity, yes — and the independence test applies to it. If the university itself holds the shares, the test still applies but universities are usually treated as independent for SEIS/EIS purposes. Check the specific entity on the cap table.
Yes. The common pattern is SEIS up to the £250,000 lifetime limit, then EIS for the balance. SEIS must be used before EIS on the same date (there is a specific order-of-shares rule).
Not legally. But in practice almost every angel and seed investor requires it. Raising without assurance means investors cannot claim relief at self-assessment, which usually kills the round.
Yes, if structured correctly. The ASA must have a long-stop date of six months or less, no interest, no refund rights, and the shares issued on conversion must themselves qualify for SEIS/EIS. Many standard ASAs on the market are not SEIS-compatible — use one that is.
