EIS clawback — when 30% relief gets withdrawn

The Enterprise Investment Scheme offers UK investors 30% income tax relief on shares in qualifying startup companies. £100,000 invested gets £30,000 of tax relief back. The downside no one warns you about: HMRC can claw the relief back if you breach a long list of conditions, and the rules are unforgiving. Most EIS clawback cases happen when investors don't realise they've breached a condition.

7-minute read

EIS 30% income tax relief is clawed back if you breach the holding rules. The main triggers: (1) selling the shares within 3 years of issue, (2) the company losing its qualifying status, (3) receiving value from the company beyond normal arms-length transactions, (4) becoming connected with the company after investing. Clawback recovers the full 30% relief plus potential interest. Loss relief and CGT deferral remain, but the headline IT relief is gone.

The basics — what EIS relief actually is

EIS gives UK income taxpayers three layers of relief on qualifying investments:

  1. 30% income tax relief on the investment, up to £1m per tax year (£2m for knowledge-intensive companies)
  2. CGT deferral — any capital gain from elsewhere can be deferred by reinvesting in EIS
  3. Loss relief — if the company fails, you can claim income tax loss relief on the net loss (after the 30% relief)
  4. IHT business relief after 2 years of holding (so the shares are outside your estate)
  5. CGT-free growth after 3 years of holding

The 30% relief is the headline. To keep it, you must hold the shares for at least 3 years from the date they were issued (not the date you applied or paid). Sell before 3 years and 30% relief is partly or fully clawed back.

The five clawback triggers

  1. Disposing of the shares within 3 years — selling, gifting (other than to spouse), or otherwise transferring. Spouse transfers are tolerated.
  2. Company loses qualifying status — e.g. it grows too large (£15m gross assets cap on a qualifying company), takes on excluded activities (banking, property development, legal services), or no longer meets the trading-not-investment test.
  3. You become "connected" with the company. Holding more than 30% of the share capital, or having a paid director role beyond the permitted "business angel" exception, triggers connection. Disconnection is hard.
  4. Receipt of value from the company. Includes loans, payments in excess of arm’s-length terms, repayment of share capital, etc. The "de minimis" threshold is £1,000 per year — receipts above this trigger pro-rata clawback.
  5. Replacement assets are sold — if you used EIS to defer a CGT gain, selling the replacement EIS shares within 3 years also crystallises the deferred gain.

Worked clawback example — early sale at 2 years

Scenario: £50,000 EIS investment, sold for £80,000 after 2 years

At investment (Year 0):

Cash invested£50,000
30% income tax relief claimed£15,000
Net cost of investment£35,000

At sale (Year 2):

Sale proceeds£80,000
Cash gain£30,000
Income tax relief clawed back (sold before 3 years)−£15,000
CGT on £30,000 gain (24% higher rate, AEA £3,000 used elsewhere)−£7,200
Net cash from £50k invested over 2 years£57,800

Despite a 60% raw return on the investment, the early sale destroys the 30% IT relief. Net cash result: £57,800 from £50k invested = 7.8% per annum after tax. Significantly worse than if held for 3 years.

If the same sale happened at Year 3 + 1 day:

Sale proceeds£80,000
IT relief retained£15,000
CGT on gain (EIS shares held 3 years = CGT-free)£0
Net cash including original IT relief£95,000

Holding one extra day adds £37,200 of post-tax value. EIS rewards patience brutally.

The receipt-of-value trap — the silent clawback

This is the EIS rule that catches careful investors out. "Receipt of value" from the company within the 3-year clawback window triggers proportional relief recovery.

Common examples:

The £1,000 de minimisHMRC allows receipts up to £1,000 per tax year as "insignificant" with no clawback. Above £1,000, the entire receipt counts and clawback applies pro-rata to the relief claimed.

Scenario: £50k EIS investment, £2,000 director’s fee received Year 2

£2,000 is above the £1,000 de minimis. The proportional clawback formula: (£2,000 / £50,000) × £15,000 relief = £600 clawback. You repay £600 of the relief via Self Assessment for the year you received the fee.

Worse — if HMRC determines the £2,000 wasn’t arm’s-length for genuine services, they can argue the full clawback amount is higher or that the entire relief should be lost.

The defensive playbook

Strategy 1: Hold for 3 years minimum, ideally 4+3 years is the income-tax-relief clawback threshold. 3 years is also the CGT-free threshold. Holding 4+ years gives a small safety buffer in case the issue-date calculation is disputed.
Strategy 2: Never accept payments or value transfers from the company in the clawback periodIf you’re a director, ensure your salary is at clear arm’s-length. Avoid receiving loans, share buybacks, or unusual benefits. Documented arm’s-length compensation is fine; informal payments are dangerous.
Strategy 3: Track the company’s qualifying statusThe company can lose status mid-investment if it: exceeds £15m gross assets, takes on excluded activities, raises too much capital, or fails the trading test. Ask the company for annual confirmation that it still qualifies. Many EIS-issuing companies have advisors who confirm status to investors.
Strategy 4: Don't take a director role in an EIS company without checking the rulesBecoming a "connected person" through directorship is the most common clawback trigger for active investors. The "business angel" exception allows a paid director role only if you weren't connected before investing and meet specific conditions.
Strategy 5: Keep the EIS3 / EIS5 certificate foreverThe EIS3 certificate issued by the company is the only proof of your relief claim. Lose it, and you can’t evidence the original investment. HMRC can ask for it 6+ years after the investment.

When clawback isn't a disaster

Even when clawback triggers, you may still keep:

The full 30% loss is the worst case. Many real clawbacks are partial — e.g. selling at year 2.5 results in only the relief proportional to the missing time being clawed back.

Self Assessment timingEIS clawback is settled via Self Assessment for the year the clawback event occurred. HMRC adjusts the original relief claim plus charges interest on the clawed-back amount from the date relief was first claimed. Late detection (e.g. HMRC investigation 3 years later) can mean significant interest charges.
