and welcome to the site. Thank you question.
JSA is taxable although you receive it gross.
It appears you have already covered your gains allowance tax year.
£15,000 worth of shares at current value would equate to approx 3,409 shares.
The profit on these shares would be (4.40-0.61) £3.79 per share making an overall gain of £12,920.
Let's assume the gain made on shares already sold is also £3.79 per share and that you sold 2,500 shares and tthat overall gain was £9,475.
As your total gain plus your salary and JSA in the tax year are unlikely to exceed the basic rate band, your CGT rate would be 18% .
Taxable gain (12,920+9,475)-11,000 = £11,395
CGT 11,395 x18% = £2,051
I hope this is helpful and answers your question.
