The 3-Year Holding Period and Disposal Events That Withdraw SEIS or EIS Relief

SEIS and EIS investors are buying time as well as shares. The headline relief is granted up front, but it only becomes secure once the investor has held the shares, and the company has continued to qualify, for at least three years. Disposing of the shares early, or doing things that count as a disposal under the rules, can claw back the income tax relief and remove the capital gains tax exemption. This article is part of our SEIS and EIS series and sits beneath the flagship pillar, the complete SEIS and EIS founders guide at /guides/seis-eis-guide-uk-startups/.

It pairs with the other two new spokes in this drop. The first deals with anti-avoidance and how HMRC test for tax motive over trading substance at /blog/seis-eis-anti-avoidance-tax-motive-trading-substance/. The second covers founders holding several roles at once at /blog/seis-eis-founder-multiple-roles-director-employee-investor/. Together they cover the three big risks to relief after the round closes: motive, holding and role.

The three-year holding period runs from the date the shares were issued, not from the date the relief is claimed and not from the date of the SEIS3 or EIS3 certificate. The investor must hold the shares continuously throughout that period, and the company must remain a qualifying company carrying on a qualifying trade for the same three years. Both halves of the requirement matter: the investor cannot dispose of the shares early, and the company cannot stop qualifying.

For most rounds, the practical effect is straightforward: the shares sit on the cap table, the company keeps trading, and the period elapses without incident. Where the period does become a live issue, it is usually because the investor wants liquidity, the company restructures, the company is sold, or the company qualifying status slips. Each of these scenarios has its own rule, and the consequences differ.

If the investor disposes of the SEIS or EIS shares within the three-year window in a transaction that is not at arm length, the full amount of income tax relief claimed on those shares is withdrawn. If the disposal is at arm length, the income tax relief is reduced on a sliding basis tied to the proceeds: in broad terms, the lower the proceeds, the smaller the portion of the original relief that survives. The CGT exemption is also lost on an early disposal, so any gain on the shares becomes chargeable.

The point of the sliding scale is to distinguish between an investor who exits early for less than they put in, where the policy is not to punish them for taking a loss, and an investor who exits early for a full return, where the relief was effectively a subsidy of a short-term gain. The mechanics are detailed and best run through with an accountant before a sale is signed.

Disposal is a wider concept than a straight sale. It includes a transfer to another person, a redemption or buy-back of the shares by the company, a gift other than to a spouse or civil partner, the cancellation of the shares, and certain reorganisations that effectively change what the investor holds. Each of these can trigger the clawback rules if it occurs within the three-year period.

It is also worth noting that not every change in the company capital structure is a disposal. A bonus issue, a sub-division of shares or a straight share-for-share exchange that meets the qualifying conditions may not count. The question of whether a given event is a disposal is technical and frequently turns on detail, so it is one to flag to an accountant whenever the cap table is about to be restructured during the holding period.

The rules contain a small but important set of carve-outs. The most familiar is death: a disposal occasioned by the death of the investor does not trigger clawback. The shares pass with the relief preserved, although the CGT exemption interacts with the rules on inheritance and the base cost of the shares for the personal representatives.

The second important carve-out is a qualifying share-for-share exchange. Where the SEIS or EIS company is taken over by another company in exchange for shares, and the conditions for a qualifying takeover are met, the new shares can be treated as if they were the original SEIS or EIS shares. The holding period continues on the new shares rather than resetting, and the relief is not withdrawn. The qualifying conditions are tightly drawn: in broad terms, the acquiring company must issue ordinary shares, the exchange must be the whole or substantially the whole of the original company shares, and certain ownership tests must be met.

• Death of the investor: relief is preserved on the shares passing to personal representatives.
• Qualifying share-for-share exchange on a takeover: the new shares step into the original holding for the three-year clock.
• Compulsory winding up for genuine commercial reasons can be treated more sympathetically than a chosen exit, but the rules are detailed.

The holding clock is not just about the investor. The company must continue to qualify for the same three years, and a number of company-side events can withdraw relief even though the investor has not sold a single share. The most important are the company ceasing to carry on the qualifying trade, the company beginning a substantial non-qualifying activity, the company becoming controlled by another company that fails the conditions, and certain "value received" payments to investors during the period.

Value-received rules deserve a separate paragraph. Payments to an SEIS or EIS investor by the company during the qualifying period, including loans, share repurchases of other shares held by them, and certain disposals at undervalue, can withdraw relief whether or not the original shares are sold. The rules are designed to stop the investor effectively recovering their money through the back door while keeping the relief.

A point that sometimes catches founders out: the three-year clock for SEIS and EIS relief runs from the date the shares are issued, not from the date the company started trading, and not from the date of the compliance certificate. For investors who subscribe across several tranches in a single round, each tranche has its own clock from its own issue date. This is one reason that the issuing schedule and the share register need to be kept accurate: an inaccurate issue date can produce a clock that does not match the relief.

Tranches issued on different dates

Where a single investor subscribes for shares across two or three issue dates in the same round, the holding period for each tranche runs from its own date. An investor who later wants to sell part of their holding may find that the earliest tranche has cleared the three years while the latest still sits inside the window. Mapping tranches to dates at the time of issue, rather than reconstructing them later, makes the position straightforward when the question comes up.

The minimum holding period and the disposal-event consequences are essentially the same under SEIS and EIS: three years from issue, sliding-scale clawback on arm length disposals, full withdrawal on non-arm length disposals, and the death and share-for-share carve-outs. The scheme differences set out in the companion article at /blog/seis-vs-eis-key-differences-founders-must-know/ are about company size, age and limits; the holding rules sit on top of both schemes in the same shape. That is helpful for founders running blended rounds, because the same diligence covers both share classes.

The holding period sits between investor and company, but it shapes the company own behaviour too. The bullet points below capture the most common actions that put relief at risk and the actions that do not.

• High risk: buying back SEIS or EIS shares early, repaying value through loans or service contracts, varying share rights to add preferences.
• High risk: a substantial change of trade, a switch into excluded activities, or a takeover that does not meet the qualifying share-for-share conditions.
• Lower risk: business as usual trading, hiring, customer acquisition and ordinary growth funding from non-relief sources.
• Neutral with conditions: bonus issues, share splits and qualifying reorganisations, provided they meet the detailed rules.

The holding rules are also a backstop for the anti-avoidance rules covered in the companion article at /blog/seis-eis-anti-avoidance-tax-motive-trading-substance/. A pre-arranged early exit, or a payment that effectively returns money to the investor inside the three-year window, will fail both the holding tests and the motive tests. The two sets of rules reinforce each other: anti-avoidance catches arrangements engineered up front, while the holding rules catch arrangements that unwind the investment during the period it was meant to support.

Provided the shares are held for the full three years and the conditions continue to be met, a disposal after the period is normally exempt from CGT for both SEIS and EIS. The gain can be free of tax, which is a major part of the appeal for investors who back several companies expecting outsized returns from a few. The exemption only applies to the SEIS or EIS shares themselves and only where income tax relief was given and not withdrawn, so an investor whose income tax relief was clawed back also loses the CGT exemption.

A clean exit therefore depends not just on letting the three years pass, but on the company continuing to qualify, the investor not receiving disqualifying value, and the disposal itself being on arm length terms. The reward for waiting is significant, but it is contingent.

The three-year holding period is the most predictable rule in the schemes, but it interacts with disposal events, value-received rules, takeovers and the company own qualifying status in ways that are easy to overlook. A relief claim that was rock solid on day one can still be lost two years later through a poorly thought-through share buy-back or an opportunistic takeover. The flagship pillar at /guides/seis-eis-guide-uk-startups/ sets out the wider framework; the related spokes at /blog/seis-eis-anti-avoidance-tax-motive-trading-substance/ and /blog/seis-eis-founder-multiple-roles-director-employee-investor/ deal with the motive and role tests that sit alongside the holding rules. Because the consequences of getting any of this wrong are severe, take professional advice before any disposal, restructure or takeover during the holding period.
