EMI exists because early-stage companies cannot pay what good people are worth, and it is the most generous share scheme in the UK tax system by some distance. Done properly, an employee pays no income tax on the grant, nothing on exercise if the price was set at market value, and capital gains tax when they eventually sell.
Done carelessly, the same options become unapproved: income tax on exercise, possibly National Insurance too, on a gain the employee cannot yet turn into cash. The difference between those two outcomes is rarely anything to do with the commercial deal. It is a valuation that was not agreed, or a notification that went in late.
And the scheme got considerably more useful this year. On 6 April 2026 the gross assets limit went from £30 million to £120 million, the employee cap from 250 to 500, and the exercise window from 10 years to 15 (HMRC EMI guidance). Companies that had grown out of EMI, or were about to, should look again.
