What is SEIS Income Tax Relief and How Does It Work?
SEIS (Seed Enterprise Investment Scheme) income tax relief allows you to claim back 50% of your investment in qualifying early-stage companies against your income tax bill.
For example, if you invest £10,000 in an SEIS-eligible company, you could reduce your income tax bill by £5,000.
The scheme was introduced in 2012 to help small, early-stage companies raise funds by offering tax reliefs to individual investors who purchase new shares.
You can invest up to £100,000 in a single tax year and claim the 50% tax relief. That means a maximum tax reduction of £50,000 per year.
The relief is available for the tax year in which you make the investment. Alternatively, you can "carry back" all or part of your investment to the previous tax year.
Who Can Claim SEIS Tax Relief?
To claim SEIS tax relief, you need to be a UK taxpayer with enough income tax liability to offset against the relief you're claiming.
You can't be an employee of the company during the period beginning with incorporation and ending three years after your investment. Directors can sometimes qualify, however.
You mustn't hold more than 30% of the shares, voting rights, or assets of the company or any subsidiary.
The investment must be in newly issued shares paid for in cash, and you must hold these shares for at least three years.
You also can't be "connected" to the company through business partnerships or close relatives who are connected to the company.
Company Eligibility: Not All Startups Qualify
For a company to be eligible for SEIS investment, it must be UK-based with a permanent establishment in the UK.
It must be carrying out a new qualifying trade. Certain activities like property development, financial services, and farming are excluded.
The company's gross assets mustn't exceed £200,000 before investment. It must have fewer than 25 full-time employees at the time of investment.
There's a maximum SEIS fundraising limit of £150,000 in total for the company. The money raised must be used for qualifying business activities within three years.
The company must not be listed on a recognised stock exchange. It must not have arrangements to become listed at the time of investment.
How to Claim Your SEIS Relief
After making your investment, the company will apply to HMRC for SEIS approval. Once granted, they'll issue you an SEIS3 certificate.
With this certificate, you can claim your tax relief through your self-assessment tax return. The relief is claimed in the "Additional information" pages.
If you want to carry back the relief to the previous tax year, you'll need to specify this on your tax return.
I once helped a client who nearly missed out on £20,000 of relief because they'd misplaced their SEIS3 certificate. We contacted the company just in time to get a replacement before the filing deadline.
Remember, you must hold the shares for at least three years. If you sell them before then, HMRC will claw back the relief you've claimed.
If you're using an accountant, make sure to give them your SEIS3 certificate when preparing your tax return.
Watch Out for These Common Pitfalls
The relief will be withdrawn if you sell your shares within three years of the investment date.
You'll also lose the relief if you receive "value" from the company within this three-year period. This includes loans or assets provided at less than market value.
The relief is limited to the amount of income tax you actually owe in the relevant tax year. You can't claim a refund for more than you've paid.
You can't use both SEIS and EIS (Enterprise Investment Scheme) relief for the same shares.
The company must remain qualifying throughout the three-year period after your investment. If not, your relief could be at risk.
Additional Tax Benefits Beyond Income Tax Relief
Beyond the 50% income tax relief, SEIS offers other tax advantages, including 50% Capital Gains Tax (CGT) reinvestment relief on gains invested in SEIS shares.
When you eventually sell your SEIS shares, any profit is free from CGT if you've held the shares for at least three years.
If your SEIS shares are sold at a loss, you can claim loss relief against income tax rather than capital gains tax. This potentially saves you more money.
SEIS shares also qualify for Inheritance Tax exemption after being held for two years.
You can even make SEIS investments jointly with your spouse. This allows both of you to claim the tax reliefs without needing to transfer the shares.
Final Thoughts
SEIS income tax relief is one of the most generous tax incentives available to UK investors.
When used properly, it significantly reduces your tax bill while supporting innovative early-stage businesses that might otherwise struggle to find funding.
Always consult with a tax professional before making SEIS investments. This ensures you meet all eligibility requirements and understand the risks involved.
Remember that both timing and compliance with HMRC guidelines are crucial for successfully claiming your relief.
