Hello, I am Keith, one of the experts on Just Answer, and pleased to be able to help you with your question.
If you are going out of this business then Entrepreneurs' Relief (ER) will limit you Capital Gains Tax (CGT) exposure to a 10% flat rate. This used to be a generous concession, but as CGT is now levied at 10% or 20% or a combination of the two rates depending on your income including the gain in the tax year of disposal the savings are less significant. There are some conditions and limitations, hoops you must go through before ER applies. You can find them summarised here:
I do hope that you have found my reply of assistance.
The Gov UK link I gave you makes it clear that you have to be in business for at least a year to be entitled to ER [see Paragraph 1].
