The 3-Year EIS Holding Period Rule
The short answer? You need to hold your EIS shares for at least 3 years to keep the tax relief.
This 3-year clock starts either from when the shares were issued or when the company started trading (whichever comes later).
Sell before the 3 years are up, and HMRC will want their money back through what they call a “clawback” of the relief you’ve already claimed. Selling before the required period also means you lose disposal relief and CGT disposal relief on your EIS shares, so any gains may become taxable.
There’s no sliding scale or partial relief for holding shares for, say, 2 years and 11 months. The rule is absolute. To claim relief, you must meet the full holding period requirement.
How Income Tax Relief Works with EIS
When you invest in EIS shares, you can claim 30% income tax relief on investments up to £1 million per tax year.
You receive income tax relief by claiming EIS income tax relief through your self-assessment tax return or, if you are paid via PAYE, by adjusting your PAYE tax code using the EIS3 certificate to claim EIS tax relief directly through the PAYE system.
This limit increases to £2 million if you’re investing in knowledge-intensive companies. If you have invested in knowledge intensive companies, your maximum investment eligible for relief increases accordingly.
You can claim this relief in the tax year you invest or carry it back to the previous tax year for added flexibility. You must claim EIS tax relief for the actual amount invested, not the amount of tax relief you wish to receive.
To keep this relief, you must hold those shares for the full 3-year period. There’s no wiggle room here.
If you sell even a portion of your shares early, HMRC will claw back the corresponding percentage of tax relief. The income tax relief claimed will be reduced, and your income tax bill or income tax liability may increase as a result.
Claiming income tax relief is essential to benefit from EIS tax reliefs, and you must keep records of the income tax relief claimed for each investment.
Capital Gains Tax Benefits and Timing
One of the biggest perks of EIS investments is the Capital Gains Tax exemption on any profits when you sell your shares.
This exemption only applies if you’ve held the shares for at least 3 years and claimed the income tax relief.
There’s also CGT deferral relief, which lets you postpone tax on other gains by reinvesting them into EIS shares. This is known as capital gains deferral relief, and you can claim capital gains deferral by completing the capital gains summary pages of your tax return.
The deferred gain becomes taxable when you sell your EIS shares, regardless of how long you’ve held them. Deferred gains are treated as chargeable gains in the tax year of disposal, and you may need to pay capital gains tax or pay CGT at that point.
I once helped a client who’d forgotten this distinction and was surprised when his deferred gain became taxable after an early sale. Timing matters tremendously.
Claiming deferral relief arose from reinvesting a capital gain into EIS qualifying shares, and the process for claiming EIS deferral relief must be completed within the relevant or future tax years.
Deferring gains can help manage your tax liability across future capital gains, but you must follow the correct procedures to claim relief.
