First, some background for those who don’t yet know what the SEIS is. The Seed Enterprise Investment Scheme (SEIS) is a government initiative that offers up some of the most attractive tax breaks available in the UK to equity investors. In order to access them, one needs to invest in the shares of a small, unlisted company – “small” in this case meaning 250 employees or less, and with maximum gross assets of £15 million. In some cases it’s even possible to invest with SEIS in listed companies, but only those listed on small exchanges like AIM or ISDX. You can watch a great video on it here.
