EIS and SEIS Tax Relief Rules for 2026/27

The Enterprise Investment Scheme (EIS) and Seed Enterprise Investment Scheme (SEIS) provide qualifying investors with upfront income tax reductions of 30% and 50% respectively. These tax incentives directly reduce your annual income tax liability based on the amount you invest in eligible UK businesses. In the 2026/27 tax year, you can offset these reliefs against your self-assessment liabilities, provided you meet HMRC holding requirements.

Key takeaways

For a quick reference of the core tax incentives, the main parameters of EIS and SEIS for the 2026/27 tax year include:

• EIS Tax Relief Rate: 30% of your investment amount applied as a direct reduction to your UK income tax liability.
• EIS Annual Investment Limit: Up to £1 million in standard qualifying companies, rising to £2 million if the excess is invested in knowledge-intensive companies.
• SEIS Tax Relief Rate: 50% of your investment, reflecting the higher risks of seed-stage businesses.
• SEIS Annual Investment Limit: Up to £200,000 for the tax year.
• Minimum Holding Period: A 3-year minimum holding period applies to both schemes to retain the tax relief.
• Carry-Back Election: Both schemes allow you to carry back relief to the preceding tax year.

How do EIS and SEIS tax relief rates compare in 2026/27?

Comparing these schemes side-by-side helps clarify their specific rules, caps, and rates. The table below outlines the core attributes of both programmes under the latest regulations, confirming that the EIS income tax relief rate remains at 30%.

What is the Seed Enterprise Investment Scheme (SEIS) relief?

The Seed Enterprise Investment Scheme (SEIS) is an HMRC-backed tax incentive that encourages investment in early-stage start-up companies by offering individuals up to 50% income tax relief on investments up to £200,000 per year. According to the Seed Enterprise Investment Scheme Income Tax and Capital Gains Tax Reliefs Helpsheet HS393, the scheme targets very young businesses.

To claim SEIS tax relief, you and the issuing company must satisfy several statutory eligibility rule criteria:

• The investment must be in new, fully paid-up ordinary shares.
• The issuing business must have been trading for less than three years.
• The company must have gross assets of £350,000 or less before the share issue.
• The business must have fewer than 25 full-time equivalent employees at the time of issue.

As a practical example, if you invest £20,000 into a qualifying SEIS business, you receive a direct tax reduction of £10,000. This deduction is subtracted directly from your total UK self-assessment liability.

What is the Enterprise Investment Scheme (EIS) relief?

The Enterprise Investment Scheme (EIS) is a government programme designed to help mid-sized start-up companies raise finance by offering a 30% income tax reduction to individuals who purchase new shares. Under standard regulations, you can invest up to £1 million in most qualifying scale-up businesses.

If you invest in knowledge-intensive companies (KICs), this annual limit extends to £2 million, provided that any amount over £1 million is specifically committed to KICs. Knowledge-intensive companies are specialised businesses involved in heavy research and development or original intellectual property creation.

For instance, if you invest £100,000 in a standard qualifying EIS firm, your income tax liability reduces by £30,000. This write-off reduces the net cash risk of your early-stage venture investment.

How does the three-year holding period work?

The minimum holding period for both EIS and SEIS shares is three years from the date of the share issue to retain your tax relief. Selling or disposing of the shares before this three-year period ends initiates an HMRC clawback of the original income tax discount. If you sell early, you must notify HMRC within 60 days to repay the claimed relief.

If the company experiences an early exit or insolvency, specific disposal rules apply. Income tax relief clawbacks do not apply if a company fails and winds up, allowing investors to claim loss relief on the remaining net capital at risk.

Can I carry back EIS and SEIS relief to a prior tax year?

You can elect to carry back your qualifying EIS or SEIS investments to the tax year immediately preceding the current one. This structured tax planning mechanism allows you to treat some or all of an investment made in 2026/27 as if it occurred in 2025/26.

This carry-back option is vital if your income tax bill for the current year is lower than the available relief. By applying the relief to the prior year, you can claim a refund from HMRC for tax you already paid.

What are the rules and restrictions for claiming?

Claiming tax relief requires adhering to several eligibility criteria and administrative procedures set by HMRC to prevent artificial tax avoidance schemes:

1. Connected Persons: You must not be 'connected' to the issuing business, which means you cannot hold more than a 30% stake in the shares or voting rights.
2. Employment Restrictions: You and your close associates cannot be employees or partners of the company, though certain business angel directors can claim under specific rules.
3. Compliance Certificates: You must obtain an official EIS3 or SEIS3 compliance certificate from the issuing company before claiming tax relief.
4. Tax Reducer Cap: Your total annual relief cannot reduce your actual tax liability to less than zero.

Has VCT tax relief changed for 2026/27?

There are key differences in tax relief rates between Venture Capital Trusts (VCTs) and the EIS for the 2026/27 tax year. While the Enterprise Investment Scheme (EIS) tax relief rate remains at 30%, VCT tax relief dropped to 20% on 6 April 2026.

Some publications incorrectly stated that EIS tax relief would decrease. Prominent tax professionals confirm that only the VCT incentive decreased, while the core EIS rate remains at 30%.
