SEIS: A Technical Overview for Advisers

This guide to SEIS for advisers is the reference we wish every client conversation could start from: the qualifying conditions on both sides, the procedure from advance assurance to SEIS3, the reliefs and their withdrawal events, and the pitfalls that actually arise in practice. It assumes professional familiarity with the venture capital schemes and keeps the commentary tight.

Figures are the current limits, in force for shares issued on or after 6 April 2023. Primary sources are linked at the end, and the plain-English companion pieces for clients sit across our SEIS Explained section.

SEIS for advisers: the scheme in outline

SEIS provides income tax and capital gains reliefs for individuals subscribing cash for new ordinary shares in small, early-stage qualifying companies. Relief is contingent: the company must satisfy its conditions at issue and for the following three years, the investor must satisfy theirs, and procedure must be followed before any claim exists. The scheme sits alongside EIS and VCT, and where a company uses both schemes, SEIS money must be raised before EIS money on the same or an earlier share issue.

Company conditions

The excluded activities list is the familiar one: dealing in land, commodities or shares; banking, insurance and money-lending; leasing and royalties in most forms; legal and accountancy services; property development; farming and woodlands; hotels and nursing homes; energy generation. Where a client’s trade brushes any of these, treat classification as a substantive question rather than a formality.

Investor conditions

• Subscription in cash for new ordinary shares, fully paid at issue. No preferential rights that de-risk the instrument.
• No connection: broadly, no more than 30% of shares, votes or assets (with associates), and no employment. Directors are not treated as employees for this purpose, so a paid director can qualify, which is a frequent planning point for angels taking board seats.
• Annual limit: £200,000 of SEIS subscriptions per tax year, with carry back of all or part of the amount to the previous year, subject to that year’s limit.
• No linked loans or reciprocal arrangements designed to return value.
• Holding period: three years from issue for the reliefs to become final.

The reliefs, technically

• Income tax relief at 50% of the amount subscribed, capped by the annual limit and by the tax otherwise due. Claim window: up to five years after the 31 January following the tax year of the investment.
• Reinvestment relief: 50% of chargeable gains reinvested into SEIS shares in the same tax year exempt, within the annual limit, claimed with the income tax relief.
• Disposal relief: gains on the SEIS shares exempt after three years where income tax relief was given and not withdrawn.
• Share loss relief: allowable loss (net of relief retained) against income of the year or the prior year, or against gains, under the usual rules.

Procedure: assurance, SEIS1, SEIS2, SEIS3

Advance assurance remains discretionary but market-standard. HMRC will consider draft documents, the proposed issue and the funding plan; assurance letters are statements of view, not clearances, and are sensitive to changes between application and issue. Applications naming likely investors carry more weight than speculative ones.

After the issue, the company may not submit its compliance statement (SEIS1) until it has traded for four months and spent at least 70% of the monies raised. On acceptance HMRC issues the authority (SEIS2) with a unique investment reference, and the company issues SEIS3 certificates to subscribers. Investors claim via Self Assessment, or in-year through PAYE coding where appropriate, quoting the reference. Our founder-facing walkthrough is at advance assurance, and the claim mechanics for clients at claiming SEIS relief.

Withdrawal and clawback events

Relief given can be withdrawn or reduced within the three-year period on the familiar triggers: disposal of the shares (other than to a spouse or on death); the investor becoming connected; receipt of value from the company, including loans, unusual benefits and certain repayments; redemption or repayment of share capital to other shareholders; and the company ceasing to meet its conditions. Value received has a de minimis of insignificance, but the safest advice is structural: no loans, no benefits, nothing that looks like getting the money back.

The pitfalls that actually arise

• Money in before shares out. Subscription funds banked and spent before shares are issued invites argument about when the investment was made. Issue the shares against cleared funds, same day where possible.
• ASAs and convertibles. Advance subscription agreements can work if they are short-dated, non-interest-bearing, non-refundable and convert into a fixed class; anything resembling a loan risks the cash-subscription requirement. Convertible loan notes do not qualify.
• Breaching the £250,000 gross raise across multiple closes, or forgetting that de minimis state aid received earlier counts against it.
• Gross assets creeping past £350,000 where a raise closes in tranches and earlier tranches are banked first.
• The 30% test and associates. Spouses and lineal relatives aggregate. A founder’s parent investing is frequently connected.
• SEIS/EIS ordering: issue the SEIS shares first, dated first, documented first. Same-day mixed issues cause avoidable correspondence.
• Employment drift: an investor who begins doing paid, employee-like work inside three years puts their own relief at risk.

Explaining it to clients

The adviser’s real task is expectation management: the reliefs are valuable, conditional and slow, in that order. Clients hear 50% and stop listening, so the useful framing is the timeline, money now, certificate after HMRC processes the compliance statement, reliefs final after three years, and the golden rule that the investment must stand up without the tax. Our plain-English pieces are written to be sent to clients, starting with what SEIS is and how the reliefs work.

Receipt of value: the list worth memorising

Most clawback correspondence starts with value received, because the category is wider than clients assume. Within the period, treat as dangerous: repayment or redemption of any share capital; loans from the company to the investor or their associates, including directors’ loans that drift; provision of assets or services below market value; payment of non-commercial remuneration; and settlement of an investor’s personal liabilities. Insignificant amounts are tolerated; patterns are not. The clean advice is behavioural: for three years, nothing flows from company to investor except properly declared dividends and arm’s-length pay for real work.

Share rights in practice

The shares must be ordinary, fully paid in cash, and free of preferential rights that de-risk the holding: no preferential rights to assets on a winding up, no cumulative or fixed preferential dividends, no redemption rights. Growth-share and multi-class structures need review against these tests before assurance rather than after; a seemingly cosmetic class right can disqualify an issue. Where a cap table already carries preference from a prior non-scheme round, the SEIS class must be genuinely ordinary notwithstanding what sits beside it.

Timing interactions advisers get asked about

• SEIS then EIS in one raise: issue SEIS shares first, on an earlier date, with board minutes and the register unambiguous. Same-day issues invite enquiry.
• Reinvestment relief windows: the gain and the SEIS subscription must fall in the same tax year for the 50% exemption, with the usual matching rules; carry back of the income tax relief does not move the reinvestment year.
• Negligible value and loss claims: available once value is negligible in fact, without waiting for dissolution; coordinate the income-or-gains set-off with the client’s marginal position across the two open years.
• Death within the period: no clawback of income tax relief on death, and disposals to a spouse are not chargeable events; the spouse steps into the shoes for the remaining conditions.

The compliance file a company should keep

When relief is challenged years later, the file wins or loses it. Advise companies to hold: the advance assurance application and letter; board minutes authorising the issue; bank evidence of cleared subscription funds preceding issue; the share register and certificates with dates; the SEIS1 as filed and the SEIS2 authority; a spend analysis evidencing the 70% condition and use of funds; and copies of every SEIS3 issued. Investors should mirror the file for their own holdings, as we tell them plainly in the claiming guide.

Three client scenarios, compressed

Working with HMRC

The Venture Capital Reliefs team corresponds in writing and responds best to applications that read like they were prepared by someone who has read the manual: consistent numbers, the trade described as it will actually operate, funding round mechanics spelled out. Where a case is genuinely marginal, a well-framed assurance application asking the specific question beats a hopeful general one, and a refusal with reasons is more useful to the client than an ambiguous yes obtained by vagueness.

Drafting the assurance application: notes from practice

Applications succeed on coherence. Describe the trade as it will operate commercially, not as the pitch deck romanticises it. Reconcile every number: the raise amount in the covering letter, the business plan, and the cap table must agree. State the use of funds against the qualifying activity in plain lines, salaries, product, marketing, and avoid categories that read as excluded activity, most commonly anything that smells of property or lending. Where a fact is awkward, address it in the application rather than hoping HMRC will not notice; the team reads these documents for a living.

The pre-issue checklist

Ten minutes before completion prevents most correspondence. Confirm: cleared subscription funds received; board minutes and resolutions dated before or at issue; share class rights checked against the ordinary-share tests; register and certificates prepared with the issue date; gross assets test passed immediately before this issue, on this tranche’s numbers; employee count under 25 FTE today; the SEIS capacity arithmetic including state aid; and, where EIS follows, the SEIS issue unambiguously first. File the evidence as you go; the compliance file assembles itself if the round is run properly.

Funds, nominees and platforms

Where clients invest through SEIS funds or platforms, the shares are commonly held by a nominee with the client as beneficial owner. Relief follows beneficial ownership, so the structure works, but expect certificates to arrive piecemeal as the manager deploys, sometimes across two tax years, which complicates carry-back planning. Advise clients to diarise deployment updates and to reconcile SEIS3s against subscriptions before each filing deadline rather than after.

When something has already gone wrong

Discovering a defect after the money has moved is not always fatal. Triage in this order: first, establish whether the defect sits with the company conditions, the investor conditions, or procedure, because the remedies differ. Procedural slips, a compliance statement filed early, a certificate issued with wrong details, are usually correctable by correspondence. Investor-side defects, connection or value received, can sometimes be contained to the affected investor. Company-side defects at issue are the serious category and need advice before anyone communicates with investors, because the duty now runs in both directions. What rarely helps is silence; HMRC treats candour better than discovery.

Quick reference: the numbers

Questions advisers ask

Can a paid director claim SEIS relief?

Yes, in defined circumstances. Directors are not employees for the connection test, so a director receiving reasonable remuneration can subscribe and claim, subject to the 30% test and the other conditions.

How long does advance assurance take?

Typically several weeks, varying with HMRC workload and the quality of the application. It is an opinion in advance, not a statutory clearance.

What is the claim time limit?

Five years from the 31 January following the tax year in which the investment was made.

Do SEIS and EIS interact on the same raise?

Yes. SEIS must come first. Issue and date SEIS shares before any EIS shares, and keep the paper trail unambiguous.

Does an ASA qualify?

It can, where it is genuinely an advance subscription rather than debt: short longstop, no interest, no refund, conversion certain. Convertible loan notes do not qualify.
