Can I claim EIS tax relief on my Self Assessment tax return?
Yes. You claim EIS income tax relief through your Self Assessment return using the EIS3 certificate provided by the company, reducing your tax bill by 30% of the amount invested.
Full answer
Claiming EIS Relief on Self Assessment The Enterprise Investment Scheme (EIS) allows eligible investors to claim 30% income tax relief on investments up to GBP 1,000,000 per tax year (or GBP 2,000,000 if at least GBP 1,000,000 is invested in Knowledge Intensive Companies). To claim, you need the EIS3 compliance certificate from the investee company, which HMRC issues after approving the company's EIS status. How to Claim On your Self Assessment return, navigate to the 'Investments' section and enter the details from your EIS3 certificate. The relief reduces your income tax liability directly -- it is not a deduction from income. For example, a GBP 10,000 EIS investment generates GBP 3,000 of tax relief, reducing your tax bill pound for pound. You can carry back relief to the previous tax year if you choose, subject to the annual limits in that earlier year. Key Conditions To qualify, you must: - Not be connected to the company (broadly, holding less than 30% of shares or not being an employee, though paid directors may qualify in some cases) - Hold the shares for at least three years or relief is clawed back - Invest in newly issued shares in a qualifying trading company - Be a UK taxpayer with sufficient income tax liability to absorb the relief CGT Benefits Alongside income tax relief, EIS shares held for three or more years are exempt from Capital Gains Tax on disposal. You can also defer an existing capital gain by reinvesting the proceeds into EIS shares -- the deferred gain crystallises when the EIS shares are sold or another trigger event occurs. Loss Relief If an EIS investment fails, you can claim loss relief. The loss is calculated after deducting the 30% income tax relief already received. A higher-rate taxpayer who claimed 30% relief on a total loss effectively risks only around 38.5p per GBP 1 invested after combining income tax and loss relief. Deadlines You can claim EIS relief in the tax year the shares are issued or carry it back to the prior year. Self Assessment returns must be submitted by 31 January following the end of the tax year. Keep your EIS3 certificates as HMRC may request them during compliance checks.
