Tax benefits of EIS: case studies

Case study: tax treatment of profits with EIS - increasing net gains and deferring Capital Gains Tax (CGT)

This example shows how a profitable EIS investment can help investors to defer tax and increase after-tax gains.

Key tax benefits from a profitable EIS investment exit:

  • £50,000 investment
  • £21,000 net cost untill disposal of EIS
  • £14,000 of CGT deferred for five years
  • Zero CGT due on gains realised from the investment

Here’s how this investment example works:

  1. Investor made taxable gains of over £50,000 in 2018.
  2. £50,000 EIS investment 1 October 2019 treated as being made in 2018/19 tax year.
  3. Carry back relief yields a £15,000 income tax repayment.
  4. Capital Gains TaxCGT deferral yields a £14,000 CGT repayment.
  5. Net cost of the investment is £21,000 (i.e. £50,000 minus the CGT and income tax repayments).
  6. In May 2025, investment is sold for £250,000.

    No tax is due on the realized gain because the investment stays within the EIS qualifying conditions.
  7. The deferred CGT (£14,000) becomes due.
  8. For a net cost of £35,000, the investor has realised £250,000, plus the benefit of deferring CGT of £14,000 for approximately five years.

Case study: tax treatment of losses with EIS – minimising net loss

  1. Manager completes £50,000 investment on behalf of investor on 1 October 2019 into an EIS qualifying company.
  2. The investor had realised a taxable gain of over £50,000 in 2016, on which he had paid CGT at a rate of 20%.
  3. The investor opts to treat his investment as having been made in the 2018/19 tax year and receives an Income Tax repayment through Carry back relief of £15,000 (£50,000 @ 30%).
  4. He also claims CGT deferral and receives a CGT repayment of £10,000 (£50,000 @ 20%).
  5. The net cost of investment is therefore £25,000.
  6. In December 2020 the investment completely fails and there is no shareholder return.
  7. The deferred gain of £50,000 comes back into the charge to tax and a £10,000 CGT liability will arise.
  8. However, the loss net of Income Tax (£35,000) can be offset against the Investor's marginal tax rate of 45%, meaning that the net loss is reduced to £19,250 (38.5% of the original investment).
