Introduction: Why Startup Tax Losses Matter
Investing in early-stage businesses is exciting. The upside can be huge. But there’s a catch: risk. If things go sideways, you might face startup tax losses. That’s where SEIS and EIS loss relief steps in. It’s like a safety harness for investors who back young ventures.
In this guide, we’ll unpack how both SEIS and EIS schemes cushion you against losses. You’ll see clear examples, step-by-step how to claim relief, and even a comparison of platforms so you can dodge common pitfalls.

What Is Loss Relief?
At its core, loss relief lets you reduce the impact of a failed investment. Imagine you sink £20,000 into a promising startup. If it goes under or you sell at a discount, loss relief offsets that drop against your tax bill.
Here’s the big benefit:
- It applies to SEIS (Seed Enterprise Investment Scheme) and EIS (Enterprise Investment Scheme).
- You can claim back against income tax or capital gains tax (CGT).
- It turns what looks like a hefty startup tax losses hit into a much smaller net outlay.
Put simply, it’s the safety net that makes backing young companies more palatable.
SEIS Loss Relief Explained
The SEIS scheme offers a 50% income tax relief on your initial investment. But if things go wrong, you’re not left high and dry.
How SEIS Loss Relief Works
-
Acquisition at a Loss
If your SEIS-backed company is sold below your purchase price after holding shares for at least three years, you can claim relief on the loss. -
Voluntary Liquidation
A genuine wind-down lets you file a ‘deemed disposal.’ If your shares end up worthless, HMRC treats it as a disposal, unlocking loss relief. -
Zombie Company Scenario
No profit. No growth. Yet still trading. Your shares might be deemed of negligible value. A simple claim puts you back in line for relief.
Calculating the Loss
You invest £10,000 under SEIS. You get £5,000 back from the 50% income tax relief. If your shares become worthless, the effective loss is:
- £10,000 initial investment
- Minus £5,000 income tax relief
- Net at-risk = £5,000
That £5,000 can then be offset against your:
- Income tax at your marginal rate
- Or CGT bill
EIS Loss Relief: A Similar Safety Net
EIS is aimed at slightly more mature startups. Instead of 50%, you enjoy 30% income tax relief upfront. But loss relief kicks in on the remaining 70%.
Trigger Events
Like SEIS, EIS loss relief applies when:
- Shares are sold at a loss after three years.
- The company liquidates genuinely.
- Your shares become negligible.
The difference? You calculate relief on 70% of your original stake after the 30% upfront relief.
Comparing SEIS vs EIS Loss Relief
It’s easy to mix these up. Here’s a quick snapshot:
- SEIS
- 50% upfront income tax relief
- Loss relief on remaining 50%
-
Ideal for seed-stage risk
-
EIS
- 30% upfront income tax relief
- Loss relief on remaining 70%
- Suited to growth-stage scale ups
Both schemes help offset startup tax losses, but your strategy will hinge on the stage of the business.
How to Claim SEIS & EIS Loss Relief
Filing your claim only takes a few steps. And yes, you can use both income tax and CGT relief in different ways.
-
Against Income Tax
– Adjust your PAYE code for this tax year
– Or include form SA108 in your self-assessment for a previous year
– Deadline: 12 months from 31 January following the tax year of loss -
Against Capital Gains Tax (CGT)
– Treat the loss as a capital loss
– Deduct it from gains in the current year
– Any excess loss carries forward indefinitely
– Deadline: Four years from the end of the relevant tax year
Clear forms. Simple deadlines. And you’re off the hook for much of your startup tax losses.
In the thick of organising paperwork? Consider how a specialist platform like Oriel IPO can streamline your investment journey, from vetting to filing, making sure you don’t miss a deadline.
Worked Examples
Concrete numbers always help. Let’s break down two scenarios.
SEIS Example
- Investment: £50,000
- Upfront relief (50%): £25,000
- Company fails → shares worthless
- Effective loss: £50,000 – £25,000 = £25,000
- Higher-rate taxpayer (40%):
- Income tax relief on £25,000 = £10,000
- Total relief: £25,000 + £10,000 = £35,000
- Net cost: £50,000 – £35,000 = £15,000
EIS Example
- Investment: £80,000
- Upfront relief (30%): £24,000
- Stake sold at £40,000
- Effective loss: £80,000 – £24,000 – £40,000 = £16,000
- Higher-rate taxpayer (40%):
- Income tax relief on £16,000 = £6,400
- Total relief: £24,000 + £6,400 = £30,400
- Net cost: £80,000 – £30,400 – £40,000 = £9,600
These calculations show how you can turn potential startup tax losses into manageable sums.
