EIS and SEIS can make qualifying equity investment more attractive because eligible investors may claim tax relief. The company still raises ordinary share capital under corporate law, and the tax scheme does not turn investor money into grant income or remove the need for valid allotment, bank reconciliation and ongoing compliance.
EIS and SEIS are tax-advantaged equity schemes
HMRC's venture-capital-scheme guidance explains that qualifying companies can raise money by issuing eligible shares while investors may claim tax relief if the statutory conditions are met.
SEIS is aimed at younger, smaller companies, while EIS supports a broader qualifying growth stage. The company should confirm which scheme fits before promising investor tax treatment.
Advance assurance can help investors assess likely eligibility
Companies can apply to HMRC for advance assurance on a proposed investment. The process can give potential investors comfort that HMRC has considered the company's intended structure based on the information provided.
Advance assurance is not a guarantee that every later share issue or investor qualifies. The company still needs to complete the transaction as described and meet ongoing rules.
Investor subscriptions still arrive as equity financing
When EIS or SEIS investors transfer money, finance should reconcile each receipt to the subscription agreement and shares allotted. The bank receipt is not sales revenue.
Use the same share-capital and share-premium accounting principles as any other equity round. Tax relief belongs to the investor; the company receives equity capital.
Use the current 2026 funding and age limits
HMRC updated venture-capital-scheme limits on 6 April 2026. Businesses should use the live official guidance when planning a round because company lifetime limits, annual limits and age conditions can change.
Do not copy limits from an old pitch deck. If the company exceeds a scheme condition, investors can lose expected relief and the fundraising relationship can become contentious.
Investors need the company process completed before relief certificates are issued
After the company has met the relevant conditions and HMRC authorises the process, investors receive the appropriate EIS or SEIS compliance certificates used to claim relief.
Keep investor identity, share issue, bank receipt and compliance submissions connected. A cap table error can become a tax-relief problem as well as a corporate record problem.
Post-investment changes can affect relief
The company must continue to observe scheme requirements after the round. Certain changes to trade, ownership, share rights or use of money can affect relief during the relevant period.
Flag EIS and SEIS status in board and legal processes so later transactions are reviewed before completion. Fundraising tax relief should not be treated as finished administration once cash arrives.
Worked example: a qualifying startup closes a £1 million SEIS or EIS-style equity round with several investors. The company should still reconcile every subscription, allot shares, file SH01 and update the register exactly as it would for any other investment. Scheme compliance is an additional layer, not a replacement for company law.
Investors can care intensely about the tax relief, so the company should avoid giving informal guarantees that HMRC will approve a claim. Advance assurance and later compliance statements are evidence within the process, but investor-specific eligibility also matters. Marketing material should be carefully worded and legally reviewed.
Flag restricted activities and future corporate actions in the board calendar. A later share reorganisation, acquisition, change of trade or return of value can have scheme implications. The company should consult current 2026 HMRC guidance before taking steps that might affect investors' relief.
Keep scheme-specific use-of-funds evidence after completion. If HMRC later reviews whether money was raised for qualifying business activity, the company should be able to show how investor capital funded staff, development, commercialisation or other permitted activity.
Plan follow-on rounds carefully. A business can raise under different schemes over time, but sequencing, company age, lifetime limits and prior investments matter. Use current advice before promising that a future round will qualify under the same relief as an earlier one.
Use one compliance calendar for investor certificates, Companies House filings and scheme milestones. Different teams often own company law, tax and banking, yet one mistake can affect all three. A coordinated close process reduces the risk that investors receive shares but later wait months for the paperwork needed to claim relief.
Investor communications should separate tax-relief administration from company performance. The company can help investors with approved compliance certificates and factual scheme information, but it should not become their personal tax adviser. Encourage investors to take their own advice where individual eligibility or relief claims depend on personal circumstances.
Editorial Verdict
EIS and SEIS can make equity more attractive to qualifying investors, but the company still needs a clean ordinary share issue and bank reconciliation.
Use current HMRC guidance, document subscriptions before receipt and protect ongoing scheme eligibility. The tax benefit sits with investors; the company's responsibility is to raise and use the capital in a compliant structure.
