While intricate tax schemes like SEIS are not boosting investment, the Growth Accelerator may do the trickWhen the Seed Enterprise Investment Scheme (SEIS) was first introduced, the Chancellor announced an exemption from capital gains tax on gains realised in 2012/13 and reinvested in qualifying SEIS companies in 2012/13 or, given the correct circumstances, 2013/14. This relief has now been extended to apply to gains arising in 2013/14 that are reinvested during 2013/14 or 2014/15. While the extension is to be welcomed, it is much less generous than the relief applying to gains arising in 2012/13 as only half of the gains reinvested will be exempt.
