Hello, I'm new to UK Business Forums and looking for some advice please, if anyone can help. I'm looking to buy 50% of the shares in an existing Limited company from the current owner, who is the sole Director. He has 50 x ordinary shares and I am wanting to buy 25 x from him. My understanding is that it's a straightforward process, whereby we fill out SH04 'Notice of Sale of Shares' for Companies House, I pay the current owner the sum we have agreed and he (as the transferee) pays the 0.5% Stamp Duty to HMRC. Then we both sign a Shareholders Agreement. Have I missed anything please? Do we also need to complete a PSC01 'Person of Significant Control' for Companies House? I expect it's up to him to declare the sum I paid him to HMRC, apply for Entrepreneur's relief, etc. as part of his personal tax return...?
