Understanding SEIS and EIS: The Foundations for Tax-efficient Startups
Before diving into tactics, let’s cover the basics. SEIS (Seed Enterprise Investment Scheme) and EIS (Enterprise Investment Scheme) let investors claim back a slice of their tax bill when they back your startup. That means your pitch becomes instantly more attractive.
- SEIS offers 50% income tax relief on investments up to £100,000 per tax year.
- EIS grants 30% relief on investments up to £1 million (or £2 million in knowledge-intensive companies).
Both schemes include Capital Gains Tax (CGT) exemptions, loss relief, and carry-back options.
By positioning your business for SEIS/EIS, you’re not just structuring smartly—you’re joining a club of tax-efficient startups that investors actively seek.
Why SEIS/EIS Matter for London Startups
- London’s ecosystem is booming. Competition for angel cash is intense.
- SEIS/EIS acts like a “tax magnet.” It pulls sophisticated investors toward your offer.
- You reduce dilution risks by making equity more appealing, not cheaper.
Tax-efficient startups enjoy longer runways. More runway means more time to refine your product, build customer love, and hit milestones.
1. Choose the Right Business Structure from Day One
Your legal structure shapes every tax decision. In the UK, the most common options are:
- Sole trader
- Partnership or LLP
- Limited company
For SEIS/EIS, a limited company is almost always the best choice. Why? Corporation tax on profits is lower than personal income tax. Plus, limited liability protects your personal assets if things go awry.
Pro tip: confirm with an accountant that your articles of association and share classes align with SEIS/EIS rules. One tiny clause out of place, and you lose all reliefs.
2. Secure Advanced Assurance Early
Imagine this: you pitch to an investor, they love it, they commit… then HMRC flags an ineligibility. Nightmare.
Advanced assurance is your safety net. It’s a letter from HMRC saying your company should qualify for SEIS or EIS. It’s not 100% binding, but it reassures investors.
How to get it:
- Prepare a clear business plan.
- Detail your anticipated R&D or innovative product.
- Submit the form online, attaching your plan and articles.
With advanced assurance, you turn uncertainty into confidence. That’s exactly what high-net-worth investors look for.
3. Blend SEIS/EIS with R&D Tax Credits
If you’re building software, hardware, biotech or any “innovative” product, you might qualify for R&D tax credits. It’s often an extra £10k–£50k back from HMRC per year.
- SEIS/EIS relief shrinks your investors’ income tax.
- R&D credits reduce your corporation tax.
Double-win. And both schemes run in parallel. Just track your R&D spend—salaries, prototypes, software licences—and claim every quarter.
4. Calibrate Salary vs Dividends for Maximum Efficiency
Paying yourself is an art. Too much salary and you trigger higher National Insurance. Too many dividends and you risk cashflow gaps.
A balanced approach:
- A modest salary up to the National Insurance primary threshold.
- Dividends for the rest, taxed at a lower rate.
This hack is standard among tax-efficient startups. It frees up cash for ops while keeping you comfortable. Chat with your accountant to fine-tune the split.
5. Leverage SEIS for Your First Round, EIS for Later Stages
One common trap: using EIS too early. You lose the bigger reliefs SEIS offers. Instead:
- Round 1: SEIS, up to £150,000.
- Round 2 and beyond: EIS, up to £5 million annually.
Different investors love different schemes. Some angels prefer the 50% SEIS relief. Others want the deeper pockets EIS offers. Offering both in sequence helps you land good backers at each stage.
6. Harvest Loss Relief When Things Don’t Go as Planned
Tax-efficient startups aren’t always profitable in year one. When you do hit losses, don’t let them vanish in limbo. Claim loss relief under SEIS/EIS.
How it works:
- You offset your losses against your other taxable income.
- You lower your personal tax bill—sometimes by thousands.
It’s an often-overlooked gem. Oriel IPO’s educational hub walks you through the exact HMRC forms and calculations.
7. Reward Your Team with EMI Share Options
Hiring in London is pricey. You need brilliant people, not just cash. Enter EMI (Enterprise Management Incentives).
EMI options let you grant tax-efficient share rights to employees:
- No upfront tax on grant.
- CGT on eventual sale at 10%.
- Exit-ready talent, aligned incentives.
Combine EMIs with SEIS/EIS. Your entire team becomes invested—in every sense of the word.
8. Keep an Eye on VAT Thresholds and Schemes
VAT can be a headache, but also a mini cashflow driver. If your turnover nears £90,000 (2025 threshold), consider:
- Flat Rate Scheme: simple bookkeeping, potential tailwind on costs.
- Cash Accounting: delay payments to HMRC until your clients pay you.
Even if you’re below the threshold, voluntary registration can let you reclaim VAT on big purchases—think equipment, software, marketing spend.
9. Stay Ahead of Legislative Changes
UK tax law shifts more often than the London weather. A tweak here, a new relief there.
- Subscribe to HMRC newsletters.
- Bookmark reliable blogs (yes, ours included).
- Schedule quarterly calls with your tax advisor.
Tax-efficient startups survive on foresight. A single regulatory update can open or close doors to millions in funding.
