Navigate Early-Stage Investing with a Share Scheme Platform
Early-stage investing can feel like a maze. You’ve got tax incentives, compliance hurdles, and a flood of startup pitches. In the UK, the SEIS and EIS schemes promise tax relief galore. In the US, the Thrift Savings Plan (TSP) sits at the heart of federal pension saving. Two worlds apart. Two different approaches.
Whether you’re a founder, investor or adviser, you need clarity. A friendly share scheme platform can tie it all together. Something commission-free, subscription-based and focused on government-backed incentives.

Understanding SEIS and EIS in the UK
The Seed Enterprise Investment Scheme (SEIS) and Enterprise Investment Scheme (EIS) are two cornerstones of UK startup funding. They’re built to channel private capital into early-stage businesses. Both reward risk-takers with tax relief.
What is SEIS?
SEIS targets the very earliest stage. You can invest up to £100,000 per tax year. In return, you get:
- 50% Income Tax relief on the amount invested.
- No Capital Gains Tax (CGT) on gains from an SEIS share disposal.
- Loss relief if the company underperforms.
It’s ideal for those chasing higher tax incentives in a higher-risk zone.
What is EIS?
EIS picks up where SEIS leaves off. You can invest up to £1 million each year (or £2 million in knowledge-intensive firms). Benefits include:
- 30% Income Tax relief.
- CGT deferral on other chargeable assets.
- No CGT on disposal gains after three years.
- Loss relief to soften the blow if things go south.
It’s a nifty blend of reward versus risk for growth-stage ventures.
Key Tax Reliefs at a Glance
- Up to 50% Income Tax relief (SEIS), 30% (EIS).
- CGT exemptions or deferrals.
- Loss relief cushions the downside.
- Inheritance Tax relief after two years.
SEIS and EIS pair well when you want tiered tax planning. First SEIS, then EIS—stack the shields.
The US Thrift Savings Plan at a Glance
The Thrift Savings Plan is America’s federal retirement savings programme. Think of it as a 401(k) for civil servants, military personnel and certain government employees. It’s run by the Federal Retirement Thrift Investment Board.
Origins and Purpose
Introduced in 1986, the TSP was born to simplify pension saving. It offers low-cost funds, broad diversification and a hands-off approach. Unlike the UK’s SEIS/EIS, it’s not about startups. It’s about retirement security.
Investment Choices
Participants pick from a handful of funds:
- G Fund: Government securities, zero risk.
- F Fund: Fixed income, moderate risk.
- C Fund: Large-cap equities.
- S Fund: Small- to mid-cap equities.
- I Fund: International developed markets.
- Lifecycle funds that auto-reallocate over time.
You can’t back a biotech startup, but you get a ready-made portfolio. Low fees, steady growth, minimal fuss.
Strengths and Limitations
Strengths:
- Ultra-low expense ratios.
- Automatic diversification.
- Hands-off compounding for decades.
Limitations:
- Locked in until retirement age.
- No direct startup equity.
- Strict eligibility (federal workforce only).
Side-by-Side Comparison: SEIS/EIS vs TSP
How do these schemes stack up? Think tax relief versus retirement saving.
-
Objective
• SEIS/EIS: Boost startup growth.
• TSP: Build long-term retirement wealth. -
Tax Incentives
• SEIS/EIS: Upfront relief on investments, CGT benefits, loss relief.
• TSP: Contributions are pre-tax; withdrawals taxed as income in retirement. -
Risk Profile
• SEIS/EIS: High risk, early-stage businesses.
• TSP: Low to moderate risk via diversified funds. -
Accessibility
• SEIS/EIS: Open to UK taxpayers investing in eligible startups.
• TSP: Exclusive to US federal employees. -
Flexibility
• SEIS/EIS: Liquidity depends on company exit, typically 3+ years.
• TSP: Penalties for early withdrawal, but easier to rebalance.
No scheme is universally “better”. It’s about your goals. Looking for hard growth and tax relief? SEIS/EIS wins. Want classic retirement saving? TSP takes centre stage.
