Mitt, thank you for your reply and for additional information.
Basically, any gain arising from sale of shares would be chargeable to capital gains tax. You would claim gains allowance against the gain before CGT is calculated (gains allowance in current tax year is £11,000). CGT rate is 18%, 28% or a combination of both depending on your income including the gain in the year of sale.
Your question is -
If things go to plan then the shares will be worth a lot more in 5 years time. I want to make sure I pay the right tax here in the UK on being given these shares, but at the same time I do not want to overpay. What is the best way for me to deal with this?
Let's consider the scenario post 2018 as any sale prior to that is unlikely to generate a sizeable gain to worry about.
You say you would have to offer then to fellow shareholders before to others. The most tax efficient way to mitigate your CGT would be to sell your shares piecemeal to fellow shareholders each tax year to take advantage of your capital gains allowance spread over tax years.
The worst scenario is CGT at 28%.
I hope this is helpful and answers your question.
