Introduction
You’ve poured your heart, sweat and equity into your startup. Under the Seed Enterprise Investment Scheme (SEIS) and Enterprise Investment Scheme (EIS), you’ve unlocked vital tax breaks. But have you thought about SEIS equity protection when you’re not around? Estate planning for founders isn’t just about drafting a will. It’s about ensuring your shares—and your legacy—stay intact. Let’s explore how you can bunker down your SEIS/EIS equity stakes, dodge inheritance tax surprises and sleep easier at night.
What Are SEIS and EIS—and Why Estate Planning Matters
SEIS and EIS are government-backed schemes to fuel UK innovation. They reward investors (and founders!) with:
- Income tax relief (up to 50% under SEIS, 30% under EIS)
- Capital Gains Tax deferral
- Loss relief if things go south
But here’s the catch: your SEIS/EIS shares still sit inside your personal estate. On death, these shares could face up to 40% Inheritance Tax. That’s where SEIS equity protection comes in.
Think of your shares like prized records. If you don’t lock them in a fire-proof safe, they could burn—or be grabbed by the taxman.
Key Risks to SEIS Equity Protection
Ownership Gaps
• No will = no guidance on who inherits your SEIS/EIS shares.
• Joint accounts can muddy the waters.Disputed Shares
• Family feuds over value.
• Beneficiaries unaware of the tax benefits.Inheritance Tax (IHT) Hit
• Up to 40% IHT if Business Property Relief (BPR) isn’t applied.
• Timing matters—shares need minimum two-year holding.Lack of Liquidity
• Estate can’t sell shares quickly.
• Forced discount sales at rock-bottom prices.
Each of these can gut SEIS equity protection without the right planning.
Estate Planning Tools to Safeguard SEIS Equity Protection
Wills and Trusts
- Simple Will: Specifies who gets what.
- Discretionary Trust: Keeps shares out of your estate for IHT, offering full SEIS equity protection.
- Life Interest Trust: Beneficiaries enjoy dividends while assets remain outside the estate.
Shareholder Agreements
- Include buy-sell clauses triggered on death.
- Define valuation methods to avoid squabbles.
Business Property Relief (BPR)
- Qualifying shares get 100% relief from IHT after two years.
- Constantly review eligibility (no more than 50% of trading activities).
