If you leave a company before the tax year end and sell the shares, receiving the income before the tax year ends and pay basic rate of tax, but the company subsequently puts that through on your wage slip as in the new tax year, when you are now a higher rate tax payer at a new company, do you have to pay higher rate on those funds? Additionally, although the trustee managing the scheme has said all of the funds were sold in the prior tax year, the company you worked for then pays a small portion it underpaid you in the new tax year, do you have to pay tax on the full sale of the shares?
