I am acting for the estate of an individual who held enterprise investment scheme (EIS) and seed enterprise investment scheme (SEIS) shares at the date of his death in May 2023. The individual purchased the shares in January 2021, and claimed income tax relief in full, as well as deferring a gain made from the sale of an investment property into the EIS shares.

The executors of the estate are now looking to dispose of the shares at a gain. What are the tax implications for the deceased and the executors?
