Why SEIS Matters for Tax-Advantaged Investment
You’ve built a promising prototype. You’ve nailed the pitch. Now you need capital. But early-stage funding feels like climbing Everest in flip-flops. Enter SEIS—the Seed Enterprise Investment Scheme. It’s your ticket to tax-advantaged investment, making risky seed funding less scary for angels and sophisticated investors alike.
SEIS isn’t just another scheme. It’s a lifeline for UK startups. Investors get up to 50% income tax relief on investments up to £200,000. They escape Capital Gains Tax, sink deeper into loss relief, and even dodge Inheritance Tax after two years.
Imagine this: you pitch your startup, and you can show a potential backer that their money won’t just sit under scrutiny—it’ll slash their tax bill. That’s powerful.
What Is SEIS?
At its core, SEIS is a government-backed programme launched in 2012. Its aim? To boost the UK economy by funneling funds into small, seed-stage companies. SEIS has four headline benefits for investors:
- 50% upfront income tax relief on qualifying investments (up to £200k per tax year).
- No Capital Gains Tax (CGT) on gains made from SEIS shares if held for at least three years.
- Loss relief when things flop—investors can offset losses against income tax.
- Inheritance Tax (IHT) relief, provided shares are held for two years or more.
For founders, the upside is clear: you become more attractive to angels and early-stage funds. You tap into a pool of motivated backers who know they’re stepping into a tax-advantaged investment.
Key SEIS Eligibility Criteria
Before you pop the champagne, check you tick the following boxes:
- Your company is UK-registered and trading for less than three years.
- You have no more than 25 full-time employees.
- Gross assets are under £350,000 (new rules from April 2023).
- You haven’t raised more than £250,000 via SEIS to date.
- Your trade is not excluded by HMRC (eg. property development, banking, legal services).
Note: Non-UK businesses can qualify if they have a “permanent establishment” in the UK. Clever, right?

Step-by-Step: Securing SEIS Eligibility
-
Confirm your trading history
– Under three years? Good. Under two? Even better. -
Check your trade isn’t excluded
– Avoid financial services, property, legal/accounting, electricity generation. -
Gather your documents
– Bank statements, articles of association, pitch deck, three-year financial projections. -
Apply for Advance Assurance
– Submit your details to HMRC for a provisional green light (allow 4–8 weeks). -
Issue shares and finalise investment
– Once you have HMRC’s letter, approach investors with confidence. -
Submit your SEIS compliance statement
– Within six months of fundraising, send form SEIS1 to HMRC.
By following these steps, you ensure a smooth journey from application to share issuance—and you can tout that coveted tax-advantaged investment status to your angels.
How Investors Calculate SEIS Tax Relief
Investors often grunt at tax forms. Here’s the quick maths:
- Invest £20,000 → claim £10,000 as income tax relief.
- Hold SEIS shares for 3 years → pay zero CGT on gains.
- If the business fails → offset losses against income tax at their highest rate.
It’s why SEIS is the poster child of tax-advantaged investment.
SEIS vs EIS: Picking the Right Scheme
SEIS and EIS are siblings in the government’s tax-incentive family. They share some rules but differ:
- SEIS is for seed-stage (<3 years, <25 employees, <£350k assets). Investors get 50% income tax relief.
- EIS suits slightly more mature SMEs (<7 years, <250 employees, <£15m assets). Investors get 30% income tax relief and CGT deferral options.
You can even mix SEIS and EIS in a single round—issue SEIS shares first, then EIS. It’s like a tax-relief tag team.
Real-World Tips to Maximise SEIS Impact
- Time your raise: plan around your financial year to optimise when investors claim relief.
- Engage early: secure Advance Assurance before marketing your round.
- Leverage Oriel IPO’s community: pitch at our curated events. Make connections. Get feedback.

Monitoring and Compliance
SEIS isn’t “set and forget.” Post-raise, keep HMRC happy:
- File annual returns.
- Update HMRC on any significant changes (eg. new funding rounds or asset acquisitions).
- Maintain records: share registers, investor details, and spending proofs.
A little diligence now saves a world of pain if HMRC comes knocking.
