EIS, SEIS and VCT Tax Relief: Complete Guide 2026/27 -- 50% SEIS, 30% EIS, CGT Deferral and Loss Relief

How EIS Works -- 30% Relief, CGT Exemption and CGT Deferral

The Enterprise Investment Scheme allows UK income taxpayers to invest in newly issued ordinary shares in qualifying unquoted companies and receive a 30% reduction in their income tax bill. This is a direct tax credit -- it reduces the amount of tax you owe, not simply your taxable income. If you invest GBP 50,000 into an EIS company, you immediately save GBP 15,000 in income tax, as long as you have at least that much income tax to offset.

The annual investment limit is GBP 1,000,000 per investor per tax year. Unused relief cannot be carried forward, but the subscription can be carried back to the previous tax year. For knowledge-intensive companies the limit doubles to GBP 2,000,000.

Three tax reliefs are available under EIS -- an investor can use all three simultaneously:

• Income tax relief: 30% of the amount subscribed, clawed back if shares sold within 3 years.
• CGT exemption: gains on EIS shares held for at least 3 years are fully exempt from CGT -- even if the gain is GBP 1,000,000 or more.
• CGT deferral: any capital gain from a separate disposal can be deferred by reinvesting into EIS shares. There is no cap on the amount deferred. The gain re-crystallises when the EIS shares are sold.

How SEIS Works -- 50% Relief and CGT Reinvestment

The Seed Enterprise Investment Scheme targets the very earliest stage of a company's life -- the first GBP 250,000 of investment, in companies with fewer than 25 employees and gross assets below GBP 350,000 that have been trading for fewer than 3 years. Because the risk is highest at this stage, the relief is more generous: 50% income tax relief rather than 30%.

An investor can put up to GBP 200,000 into SEIS-qualifying companies in a tax year and claim GBP 100,000 of income tax relief. Like EIS, the relief is a direct credit against your tax bill and requires that you owe at least that much income tax. The shares must be held for at least 3 years.

SEIS has a unique CGT feature not available under EIS: SEIS reinvestment relief. If you have realised a capital gain in the same tax year as your SEIS investment (or carry back to the prior year), you can exempt 50% of that gain from CGT by reinvesting an equivalent or greater amount into SEIS shares. This is a permanent exemption, not a deferral.

How VCTs Work -- 30% Relief, Tax-Free Dividends and CGT Exemption

A Venture Capital Trust is a UK-listed investment company that pools investor capital and deploys it into a portfolio of qualifying unquoted small businesses. Unlike EIS and SEIS -- where you invest directly into individual companies -- with a VCT you buy shares in the listed trust itself. The trust manager selects and manages the underlying portfolio.

Investors subscribing for new VCT shares receive 30% income tax relief on up to GBP 200,000 per tax year -- a maximum saving of GBP 60,000. The shares must be held for 5 years (not 3). In addition:

• Dividends from VCT shares are completely tax-free -- they are not subject to the GBP 500 dividend allowance and do not count as income for personal allowance taper purposes.
• Capital gains on disposal of VCT shares are CGT-exempt regardless of holding period (as long as the income tax relief was not claimed within the 5-year window -- if you sell within 5 years the income relief is clawed back).
• VCTs do not offer CGT deferral relief or income loss relief -- these are EIS-only features.

VCTs charge ongoing management fees (typically 1.5--2% per year), which reduce net returns. VCT shares often trade at a discount to net asset value on the secondary market, so investors should not assume they can exit at par after 5 years.

EIS, SEIS and VCT -- Side-by-Side Comparison

CGT Deferral via EIS -- Deferring Property and Share Gains

One of EIS's most powerful and underused features is CGT deferral. If you have realised a capital gain from any source -- selling a rental property, a business, listed shares, or other assets -- you can defer paying CGT on all or part of that gain by investing the equivalent amount into qualifying EIS shares. The investment must be made between one year before and three years after the disposal.

There is no cap on the gain that can be deferred via EIS (unlike the GBP 1,000,000 income tax relief cap). A GBP 500,000 property gain can in principle be entirely deferred by investing GBP 500,000 into EIS shares -- even if you have already used your annual EIS income tax relief allowance. The deferred gain re-crystallises and becomes chargeable when the EIS shares are disposed of -- at the CGT rates prevailing at that time, not at the time of the original disposal.

If the EIS shares qualify for CGT exemption (held 3 years and income relief was claimed), the gain on the EIS shares themselves is tax-free -- but the original deferred gain still becomes payable on disposal. The result is an effective deferral of the original CGT until the EIS exit, potentially for many years.

Practical use case: landlord sells a buy-to-let in 2026/27 realising a GBP 150,000 gain. CGT at 24% = GBP 35,280 (after GBP 3,000 AEA). Invests GBP 150,000 into EIS. CGT deferred entirely. Also claims 30% income tax relief = GBP 45,000 (subject to income tax liability). The investor has used GBP 150,000 of their GBP 1,000,000 annual EIS limit and deferred GBP 35,280 in CGT.

Loss Relief -- Protecting Against Failure

Start-up investing carries substantial risk. EIS and SEIS loss relief is specifically designed to reduce the downside by allowing the net loss (after stripping out the income tax relief already received) to be offset against income or capital gains.

Income loss relief is almost always preferable to CGT loss relief because it saves tax at marginal income tax rates (up to 45%) rather than CGT rates (18--24%). The claim can be made in the tax year the loss arises or the immediately preceding year, giving flexibility.

For a 45% additional-rate taxpayer investing GBP 100,000 in EIS:

• Income tax relief received: GBP 30,000 (30%).
• Net cost: GBP 70,000.
• If the company fails and shares are worthless: net loss for relief = GBP 70,000.
• Income loss relief at 45%: GBP 70,000 x 45% = GBP 31,500.
• Total from government: GBP 30,000 + GBP 31,500 = GBP 61,500.
• Real loss from GBP 100,000 failed investment: GBP 38,500 (38.5p per pound).

The equivalent for a SEIS investor (50% relief upfront) results in an even smaller net loss -- approximately 27.5p per pound for a 45%-rate taxpayer. This downside protection is a key reason why experienced angel investors combine EIS/SEIS with their broader risk-return analysis.

Knowledge-Intensive Companies -- Doubled EIS Limits

Knowledge-intensive companies (KICs) receive higher EIS limits because they represent the highest-innovation tier of qualifying businesses. To qualify, the company must meet at least one of two R&D expenditure tests at the time of investment:

• 15% test: at least 15% of operating costs were R&D or innovation costs in at least one of the three preceding years.
• 10% test: at least 10% of operating costs were R&D or innovation costs in each of the three preceding years.

The company must also have fewer than 500 full-time employees. KIC status unlocks: investor annual limit of GBP 2,000,000 (vs GBP 1,000,000), company annual fundraising limit of GBP 10,000,000 (vs GBP 5,000,000), and lifetime company limit of GBP 20,000,000 (vs GBP 12,000,000). The company's gross assets before investment can be up to GBP 16,000,000 (the standard EIS limit is GBP 15,000,000 before and GBP 16,000,000 after -- KICs use the GBP 16,000,000 pre-investment threshold).

For an investor with high taxable income, KIC status can deliver up to GBP 600,000 in income tax relief per year (GBP 2,000,000 x 30%). At the 45% additional rate, this effectively means sheltering GBP 1,333,333 of income from tax through EIS investment in a single year -- a significant planning tool for company founders, senior executives and high earners with liquidity events.

HMRC Advance Assurance -- How to Obtain It and Why It Matters

Advance assurance (AA) is a pre-investment check from HMRC that the proposed fundraising is likely to qualify for EIS or SEIS. It is sought by the company (not the investor), typically before shares are issued. Investors, angel networks, and EIS funds commonly require AA before committing capital.

The AA application is submitted to HMRC's SEIS/EIS team and should include: details of the company's trade; its corporate structure; use of proceeds; terms of the share issue; information about existing investors; and confirmation of employee numbers and gross assets. HMRC aims to respond within 4--6 weeks but complex cases can take longer.

Key limitations of AA: it is non-binding. If the company's facts change materially after AA is granted -- for example it changes its trade, acquires a subsidiary, or issues shares on different terms -- HMRC may deny the compliance certificate even though AA was granted. The certificate itself (SEIS3 or EIS3) is issued after the shares are subscribed and the company has satisfied the ongoing trading requirements. Investors cannot claim relief without the certificate.

Investors should also check independently whether the company has received any de minimis state aid, has any connection to them personally (connected-party rules prevent relief if the investor controls the company or is a paid director within certain limits), and whether the company has already used its maximum SEIS or EIS lifetime fundraising capacity.

Excluded Activities -- What Disqualifies a Company

Not every small unquoted company qualifies for EIS or SEIS. HMRC publishes a list of excluded activities. If the company carries on any excluded activity as a substantial part of its trade (broadly more than 20%), it will not qualify. The main excluded activities include financial services (banking, insurance, money-lending), property development, leasing, legal and accountancy services, farming, certain energy generation, hotels, care homes, and hospitality.

Borderline cases arise frequently in sectors like proptech (property software vs property development), fintech (software tools vs financial services), and agri-tech (R&D vs farming). HMRC will assess the dominant commercial activity, not just the stated intent. Always obtain advance assurance and independent legal advice where there is doubt.

Companies that receive the EIS compliance certificate and then subsequently begin an excluded activity during the 3-year qualifying period will trigger a claw-back of relief from their investors. This is a material risk in early-stage businesses that pivot -- investors should track any significant change in the company's business model during the hold period.

Practical Checklist Before Investing

Before committing capital to an EIS or SEIS investment, work through this checklist:

• Advance assurance: has the company applied for and received AA from HMRC? If not, why not?
• Connected party check: do you or any close family members control the company or hold a material interest? If so, relief may not be available.
• Previous fundraising: has the company already raised SEIS to its GBP 250,000 lifetime limit, or EIS approaching its annual or lifetime limits?
• Employee count and gross assets: does the company meet the size criteria for the scheme being used?
• Excluded activities: does any part of the trade touch a potentially excluded sector?
• Use of funds: HMRC requires that at least 80% of the money raised is used for a qualifying business activity within 2 years of investment. Ask how the company plans to deploy capital.
• Your own tax position: do you have enough income tax liability to absorb the relief claimed? Relief cannot create a refund beyond your actual liability.
• Hold period planning: can you genuinely afford to lock up the capital for at least 3 years (5 for VCT)?
